TY - JOUR T1 - Instrument response and self-noise analysis of dataloggers at the Idaho National Laboratory AN - 1855315993; 2017-001304 AB - This article describes the performance tests of three different digitizers that are currently in use by the Idaho National Laboratory seismic network and other seismic networks worldwide. The three digitizers are the PAR4CH from Symmetric Research, and the DAQ24USB-5V and DAQ24USB-XR from DAQSystems Inc. The theoretical response of each digitizer is discussed, followed by a description of how the filter coefficients were calculated. The empirically determined sensitivities are compared with the sensitivities reported by the manufacturers. Noise measurements were conducted to better understand the limitations of these digitizers. The digital filters used by all three digitizers are a combination of various sinc N filters; therefore, the filter coefficients were calculated by the convolution of N unit rectangle functions. The sensitivity as a function of the gain was measured and compared with the reported manufacturer's sensitivities. The DAQ24USB-5V and DAQ24USB-XR boards are highly accurate (1%) for the higher gain settings of 32 and 64. The PAR4CH board is the least accurate ( approximately 5%) of the three boards in this study. Noise measurements indicate that at lower sampling rates, 100 samples per second, the DAQ24USB-5V shows the lowest self-noise and is flat from 1 to 20 Hz, whereas the DAQ24USB-XR has higher self-noise at lower frequencies but is flat after 10 Hz. The PAR4CH has the flattest noise model, but the self-noise is about 30 dB greater than that of the DAQ24USB-5V. At higher sample rates, around 500 samples per second, the DAQ24USB is very flat up to about 200 Hz, after which it begins to drop, whereas the DAQ24USB-XR is relatively flat from 10 Hz till Nyquist, thus indicating that the DAQ24USB-XR is more suitable for applications that require higher sampling rates.

The model clearly predicts that a quasi-hierarchical array of subparallel cracks, oriented along the direction of the temperature gradient, is formed under small to moderately large thermally generated strain load conditions. The simulation results also demonstrate that, after an initial transient, thermal cracks propagate in a stable fashion with a velocity that scales with ~ t super(-1/2). However, under large thermal strain loads, a more complicated geometry composed of cracks that curve and coalesce develops during the later stages of crack growth.

N1 - Last updated - 2016-07-19 ER - TY - JOUR T1 - Wellbore and groundwater temperature distribution eastern Snake River plain, Idaho; implications for groundwater flow and geothermal potential AN - 1824216041; 2016-085176 AB - A map of groundwater temperatures from the Eastern Snake River Plain (ESRP) regional aquifer can be used to identify and interpret important features of the aquifer, including aquifer flow direction, aquifer thickness, and potential geothermal anomalies. The ESRP is an area of high heat flow, yet most of this thermal energy fails to reach the surface, due to the heat being swept downgradient by the aquifer to the major spring complexes near Thousand Springs, ID, a distance of 300 km. Nine deep boreholes that fully penetrate the regional aquifer display three common features: (1) high thermal gradients beneath the aquifer, corresponding to high conductive heat flow in low-permeability hydrothermally-altered rocks; (2) isothermal temperature profiles within the aquifer, characteristic of an actively flowing groundwater; and (3) moderate thermal gradients in the vadose zone with values that indicate that over half of the geothermal heat flow is removed by advective transport in the regional aquifer system. This study utilized temperature data from 250 ESRP aquifer wells to evaluate regional aquifer flow direction, aquifer thickness, and potential geothermal anomalies. Because the thermal gradients are typically low in the aquifer, any measurement of groundwater temperature is a reasonable estimate of temperature throughout the aquifer thickness, allowing the construction of a regional aquifer temperature map for the ESRP. Mapped temperatures are used to identify cold thermal plumes associated with recharge from tributary valleys and adjacent uplands, and warm zones associated with geothermal input to the aquifer. Warm zones in the aquifer can have various causes, including local circulation of groundwater through the deep conductively dominated region, slow groundwater movement in low-permeability regions, or localized heat flow from deeper thermal features.

N1 - Last updated - 2016-05-17 ER - TY - JOUR T1 - Selective Extraction of Heavy and Light Lanthanides from Aqueous Solution by Advanced Magnetic Nanosorbents. AN - 1781153606; 27018913 AB - Rare earth elements (REEs) make unique and vital contributions to our current world of technology. Separating and recycling REEs is of great importance to diversify the sources of REEs and advance the efficient use of REE resources when the supply is limited. In light of separation nanotechnology, diethylenetriamine-pentaacetic acid (DTPA) functionalized magnetic nanosorbents have been synthesized and investigated for the highly selective extraction of heavy (Sm-Ho) and light (La-Nd) lanthanides (Ln) from aqueous solutions. The results demonstrated that the separation factor (SF) between heavy-Ln and light-Ln groups reached the maximal value of 11.5 at low pH value of 2.0 in 30 min. For example, the SFs of Gd/La and Dy/La pairs were up to 10 times higher than that reported by other studies. Besides the excellent selectivity, our double-coated magnetic nanoparticles coupled with diethylenetriaminepentaacetic acid (dMNP-DTPA) nanosorbents are more advantageous in that the Ln(III) sorption was effectively and quickly (in 30 min) achieved in acid solutions with pH values as low as 2.0. Such attributes ensure a stronger adaptability to the harsh environments of REE recycling processes. Displacement phenomena were subsequently observed between the heavy-Ln and light-Ln ions that were coexisting in solution and competing for the same sorption sites, causing the increase in sorption capacity of heavy Ln on the surface of nanosorbents with time. The order of affinity of Ln(III) to DTPA-functionalized magnetic nanosorbents perfectly followed the corresponding stability constants between Ln(III) and nonimmobilized DTPA. Displacement phenomena and lanthanide contraction, as well as the surface nanostructures of DTPA-functionalized nanosorbents, significantly improved the separation factors of heavy-Ln/light-Ln pairs. The Ln(III) interaction with DTPA-functionalized magnetic nanosorbents followed the pseudo-second-order kinetics with a correlation coefficient extremely high and close to unity.

However, the innate variability of biomass resources, such as herbaceous and woody materials, and the inconsistency within a single resource due to disparate growth and harvesting conditions, presents challenges for downstream processes which often require materials that are physically and chemically consistent. Intrinsic biomass characteristics, including moisture content, carbohydrate and ash compositions, bulk density, and particle size/shape distributions are highly variable and can impact the economics of transforming biomass into value-added products. For instance, ash content increases by an order of magnitude between woody and herbaceous feedstocks (from 0.5 to 5 %, respectively) while lignin content drops by a factor of two (from 30 to 15 %, respectively). This increase in ash and reduction in lignin leads to biofuel conversion consequences, such as reduced pyrolysis oil yields for herbaceous products as compared to woody material. In this review, the sources of variability for key biomass characteristics are presented for multiple types of biomass. Additionally, this review investigates the major impacts of the variability in biomass composition on four conversion processes: fermentation, hydrothermal liquefaction, pyrolysis, and direct combustion. Finally, future research processes aimed at reducing the detrimental impacts of biomass variability on conversion to fuels and chemicals are proposed.

The spatial and temporal distribution of mixing-dependent precipitation of barium sulfate in porous media was investigated with side-by-side injection of barium chloride and sodium sulfate solutions in thin rectangular flow cells packed with quartz sand. The results for homogeneous sand beds were compared to beds with higher or lower permeability inclusions positioned in the path of the mixing zone. In the homogeneous and high permeability inclusion experiments, BaSO (sub 4) precipitate (barite) formed in a narrow deposit along the length and in the center of the solution-solution mixing zone even though dispersion was enhanced within, and downstream of, the high permeability inclusion. In the low permeability inclusion experiment, the deflected BaSO (sub 4) precipitation zone broadened around one side and downstream of the inclusion and was observed to migrate laterally toward the sulfate solution. A continuum-scale fully coupled reactive transport model that simultaneously solves the nonlinear governing equations for fluid flow, transport of reactants and geochemical reactions was used to simulate the experiments and provide insight into mechanisms underlying the experimental observations. Migration of the precipitation zone in the low permeability inclusion experiment could be explained by the coupling effects among fluid flow, reactant transport and localized mineral precipitation reaction.

Measurement of REEs at the ppt level in oily brines was possible thanks to the methods developed by INL co-authors. Isotope, geochemical, and trace analyses were performed at UW and by commercial laboratories. Basin samples contain elevated Eu and industrial sites contain elevated HREEs (Tb-Lu). In the sampled oil and gas co-produced waters Eu averages 18 ppt and can exceed 70 ppt. Respectively, these concentrations are 80 and 300 times greater than found in ocean waters (North Pacific Deep Water). In industrial power station ponds, total HREEs average 58 ppt and can exceed 190 ppt. The HREE enrichment at station ponds is also evident from their YbNASC:LaNASC ratio, which averages 16:1 for the sampled station ponds. In contrast, the ocean's YbNASC:LaNASC ratio is 1:2. Isotopic ratios range from -16.8 to 9.8 ppm for delta (super 13) C, -119 to -33 ppm for delta D, and -14 to +2 ppm for delta (super 18) O. To a first order approximation, aqueous REEs combine signatures for the geologic basin they sample, and also the field, but show little variation between formations within the same field. The basin signature for the Powder River Basin (PRB) is a Gd anomaly nearly as large as Eu after normalization, which distinguishes them from the Wind River Basin (WRB) where a similar Gd anomaly is absent. Fields also have a signature: In the PRB, field H has slight HREE enrichment over NPDW, but field P has HREE contents far greater than the NPDW. In the WRB, field M has slight HREE depletion, but field L has HREE enrichment. Although the PRB samples include common formations between fields H and P there is no detectable formation signature in the REEs independent of field signature. A formation signature is available in isotope and trace geochemistry. delta (super 13) C isotopes in some formations show evidence of biogenic natural gas, and industrial site isotopes conform to the superficial water delta (super 13) C range. All water samples are displaced to the right of the delta D-delta (super 18) O GMWL. Although all waters were sodium-chloride to sodium-sulfate type, trace geochemistry also includes information on source formation. REEs, isotopes, and trace elements offer enough information to identify the basin, field, and formation a water came from.

The project is located at the Sanford Underground Research Facility (SURF) in the former Homestake gold mine in Lead, SD. The kISMET site consists of five closely spaced near-vertical boreholes on the 4850 level that are designed for a series of hydraulic fracturing stress measurements and induced-fracture stimulation experiments. Four of the boreholes are HQ-sized holes that are 50 m in depth and will host monitoring sensors; in conjunction with a central NQ borehole they form a five-spot pattern at depth. The monitoring boreholes are located nearly equal 3 m away from the central borehole, allowing for very precise monitoring of fracture initiation and growth. The host rock is the Poorman Formation, a highly foliated phyllite that is steeply dipping at the kISMET site. Initial characterization of the site is being conducted using core samples, televiewer logs, and extensive preexisting geologic data. A straddle packer assembly will be installed at several depths in the central borehole to conduct stress measurements, and later to perform a series of hydrofracture stimulations. Preliminary analytical and numerical fracture initiation and growth model simulations conducted using existing geomechanical data for the Poorman phyllite suggest rock breakdown pressures in the range of 35-50 MPa. Two primary methods will be employed to monitor the experiments: continuous active-source seismic monitoring (CASSM) and electrical resistivity tomography (ERT); these will be complemented by passive microseismic (MEQ), pore pressure and injection rate monitoring. These experiments are aimed at understanding the effects of stress state, rock fabric, existing fractures, and stimulation approach on the character of the fracture(s) created (e.g., permeability enhancement, size, orientation, aperture), the fracturing process, and the associated induced microseismicity. Results of this research will be directly applicable to fracture stimulation and reservoir creation in Enhanced Geothermal Systems (EGS).

Some regions may have adequate thermal resources but lack the necessary permeability or deep circulating water. Exploitation of such areas for geothermal energy could occur if permeability can be enhanced enough to provide the necessary heat exchange. These improvements to the geothermal reservoir would produce what is termed an "enhanced geothermal system" (EGS). The Snake River Plain (SRP) in southern Idaho is a geological region with high heat flux ( approximately 110 mW/m (super 2) ) that has been recommended as an EGS target. In this study, we consider how the geologic and thermal history of the SRP might influence its EGS potential. We describe the fracture distribution (mean = 28.63 fractures/10 m) in a welded tuff core recovered from one of the few deep boreholes located on the SRP and provide a preliminary discussion of the likely geomechanical behavior under in situ stress. Spatial autocorrelation of fracture features is defined with geostatistical techniques and used in a stochastic simulation of possible structures in other welded tuff reservoirs. Autocorrelation scales for the continuous date are on the order of 70 meters with high subsample scale variability (56 m). Results should aid in designing criteria for a hydraulic fracturing plan that would augment the permeability and connectivity of an SRP reservoir's preexisting fracture network.

The Snake River Geothermal Consortium (SRGC) and its partners, including the University of Idaho, have won a Phase I grant under the competition, proposing to host FORGE at the Idaho National Laboratory (INL). INL has established a Geothermal Resource Research Area (GRRA) for that purpose that is an approximately 100-km2 area along the northern margin of the eastern Snake River Plain (SRP). The initial phase of the FORGE initiative called for the development of a conceptual geologic model that demonstrates the suitability of the site for EGS development. The key features of a suitable EGS site are 1) temperatures of 175 -225 degrees C within 1.5 to 4 km of the surface and 2) low permeability ( approximately 1e-16 m (super 2) ). A 3-dimensional conceptual model is presented that integrates all of the available geologic, hydrogeologic, geophysical, and temperature data for this area. The conceptual model shows a system of four nested calderas within the Picabo volcanic field filled with thick, dense flows of rhyolite tuff. Temperature estimates are based on observations from nearby deep boreholes, which suggest that the 175 degrees C isotherm may be encountered between 2.4 and 3.8 km below the land surface. The variability of heat fluxes across the plain, wide distribution of recent volcanic activity, and areas of apparent low seismic activity in the shallow crust suggest a relatively shallow, magmatic heat source that persists, distinct from the time-progressive caldera eruptions associated with development of the plain.

The western United States exhibits an excellent record of glaciation, but ongoing work across the region shows complex and yet-unexplained variation in timing of deglaciation at the end of the Last Glacial Maximum (LGM). The Trinity Alps of the southern Klamath Mountains in Northern California contain an excellent record of Pleistocene glaciation which can be used to fill a significant spatial gap in published glacial chronologies. Glacial deposits in the Trinity Alps were located using Google Earth and previously published maps, and were confirmed in the field. This study focuses on the Long Gulch and Trail Gulch Valleys at the northern margin of the Trinity Alps Wilderness Area. 24 samples from 5 moraines were taken for (super 10) Be dating, as well as 3 samples from striated bedrock. Of the 24, 10 samples were selected for exposure age analysis: 3 from bedrock, 5 from an LGM moraine and 2 from an older moraine. These ages should provide at least 2 ages of glacial abandonment within the valleys. Our new ages will be combined with 26 (super 10) Be ages collected between 2004-2012 to provide a detailed chronology of late Pleistocene glacial advances and retreat in the Klamath Mts. Our new ages will be combined with numerical modelling of glacial extent in Trail Gulch and Long Gulch using a coupled ice-flow model and mass and energy balance model. This will allow us to interpret the specific climate conditions for each glacial the two valleys. Initial dating results suggest that at least 2 pulses occurred during the LGM at approximately 15 and 19 ka. When paired with the final chronology, results from the paleoclimate modelling should provide new insights into the latitudinal variation in timing and character of paleoclimate change in the western US.

In the 1970s and 80s, geophysical and hydrological studies were undertaken, motivated by the presence of thermal wells and springs in the area. Geothermal exploration in this era culminated with the drilling of geothermal exploration wells by Sunedco Energy Development in 1979 and 1980. The test borehole temperatures were deemed too low (< 120 degrees C) for power production using technology available at the time. In January of 2014, a water well drilled to 79 meters, encountered Na-Cl-HCO (sub 3) water with a measured bottom hole temperature of 104 degrees C. Traditional magnesium corrected Na-K-Ca geothermometry of water from that well estimated the temperature of the thermal reservoir to be 204 degrees C. Due to this revived interest, new studies utilizing updated geochemical and geophysical techniques were undertaken. Present understanding of the NCV geothermal system suggests that fluid flow is associated with a fault(s) adjacent to Clifton Hill (aka Little Mountain) - a secondary horst complex rising from the floor of the Cache Valley graben. The existing data from the area is relatively sparse and is not suitable for pinpointing the location of faults thought to be acting as conduits for thermal water to travel from depth to the shallow subsurface. To investigate the locations of these faults and accurately characterize the plumbing of the geothermal system, high resolution potential field (gravity and magnetic) data was collected along lines made across the suspected location of the Clifton Hill bounding faults. Geophysical models of the subsurface using these data in conjunction with existing hydrogeological and geochemical data have aided in better determining fault locations. Groundwater level and aquifer temperature mapping in the area adjacent to the fault system has also been undertaken to explore the behavior of the shallow ground water aquifer in response to the discharge of thermal water through the system's faults.

Surface soil and vegetation samples from western Russia, Ukraine, Austria, and Hungary show consistent aged thermal fission product (super 135) Cs/ (super 137) Cs isotope ratios of 0.58 + or - 0.01 (age corrected to 1/1/15), with the exception of one sample of soil-moss from Hungary which shows an elevated (super 135) Cs/ (super 137) Cs ratio of 1.78 + or - 0.12. With the exception of the outlier sample from Hungary, surface soil/vegetation data are in quantitative agreement with values previously reported for soils within the Chernobyl exclusion zone, suggesting that radiocesium at these locations is primarily composed of homogenous airborne deposition from Chernobyl. Seawater samples taken from the Irish Sea show (super 135) Cs/ (super 137) Cs isotope ratios of 1.22 + or - 0.11 (age corrected to 1/1/15), suggesting aged thermal fission product Cs discharged from Sellafield. The differences in (super 135) Cs/ (super 137) Cs isotope ratios between Sellafield, Chernobyl, and global nuclear weapons testing fallout indicate that (super 135) Cs/ (super 137) Cs isotope ratios can be utilized to discriminate between and track radiocesium transport from different nuclear production source terms, including major emission sources in Europe.

It is composed of several modules: a nodal and semi-structured transport core solver (INSTANT), a depletion module (MRTAU), a time-dependent solver (Time Inte-grator), a cross-section interpolation and manipulation framework (MIXER), a criticality search module (CRITICALITY), and a fuel management and shuffling component (SHUFFLE). The PHISICS code has been coupled to the RELAP5-3D thermal-hydraulics code. Flexibility in the coupling among the different modules and with RELAP5-3D allows for several new integrated computational schemes and improvements with respect to current available options using NESTLE/RELAP5-3D. These schemes will be described in this paper. Moreover, the whole PHISICS package is fully parallelized, using the Message Passing Interface protocol. This allows for reduced computational times, while providing the capability to solve very detailed problems.

It can also model thermal-hydraulic systems in other inertial and accelerating frames of reference. By changing the magnitude of the gravitational vector through user input, RELAP5-3D can model thermal-hydraulic systems on planets, moons, and space stations. Additionally, the field equations were modified to model thermal-hydraulic systems in a noninertial frame, such as occur onboard moving craft or during earthquakes for land-based systems. Transient body forces affect fluid flow in thermal-fluid machinery aboard accelerating crafts during rotational and translational accelerations. It is useful to express the equations of fluid motion in the accelerating frame of reference attached to the moving craft. However, careful treatment of the rotational and translational kinematics is required to accurately capture the physics of fluid motion. Correlations for flow at angles between horizontal and vertical are generated via interpolation because limited experimental data exist. Equations for three-dimensional fluid motion in a noninertial frame of reference are developed. Two different systems for describing rotational motion are presented, user input is discussed, and examples of a modeled simple thermal-hydraulic system undergoing both rotational and translational motion are provided.

Reactor transients that result in significant two-phase flow conditions and phase change, such as reflood scenarios, loss-of-coolant accidents, and others, can tax the current capabilities of the code to model the flow fields. Current codes, such as RELAP5-3D, RELAP-7, and TRACE, have mass, momentum, and energy governing equations for only two fields (liquid and vapor). The representation of two-phase flow phenomena is improved by increasing the number of fields. Therefore, governing equations based on six fields (liquid, vapor, small bubble, large bubble, small droplet, and large droplet) are derived in this paper for implementation in RELAP5-3D.

Further, these programs incorporate other mechanisms for selecting optional code physics, input, output, data management, user interaction, and post-processing. Before being released to users, software quality assurance requires verification and validation. RELAP5-3D verification and validation are focused toward nuclear power plant applications. Verification ensures that the program is built right by checking that it meets its design specifications, comparing coding algorithms to equations, comparing calculations against analytical solutions, and the method of manufactured solutions. Sequential verification performs these comparisons initially, but thereafter only compares code calculations between consecutive code versions to demonstrate that no unintended changes have been introduced. An automated, highly accurate sequential verification method, based on previous work by Aumiller, has been developed for RELAP5-3D. It provides the ability to test that no unintended consequences result from code development. Moreover, it provides the means to test the following code capabilities: repeated time-step advancement, runs continued from a restart file, and performance of coupled analyses using the R5EXEC executive program. Analyses of the adequacy of the checks used in these comparisons are provided.

One type of nuclear power plant under study is the hybrid energy system, which uses nuclear power to generate both electricity and heat for facilities. Obviously, the second steam cycle in the nuclear power plant requires several design updates and experiments. Unfortunately, the current versions of the Reactor Excursion and Leak Analysis Program (RELAP) do not allow online data streams from experimental facilities to the computational model of the secondary steam loop. Therefore, this study develops a coupling between RELAP5 and Laboratory Virtual Instrument Engineering Workbench (LabVIEW) to model primary and secondary coolant loops. In this way, the LabVIEW model can easily be connected to an experimental apparatus to provide an online data stream and the online transient behavior of an entire nuclear power plant system. This study shows two different coupling approaches and makes qualitative and quantitative comparisons between these approaches. This paper demonstrates the results of different couplings between the primary and secondary systems of a typical pressurized water reactor (PWR). The primary loop model is a four-loop PWR. The model has been executed with steady state and transients (in this case, a loss-of-coolant accident). The results of both coupling methods have been compared with the typical RELAP5 results.

Conversion and upgrades of RELAP5-3D to FORTRAN 95 required the upgrades of these utility programs as well. Pygmalion (Pygi) and the RELAP5-3D Graphical User Interface (RGUI) are two of the utility programs that were upgraded and enhanced. Pygi creates a copy of a RELAP5-3D input file with updated initial condition information. From the restart/plot file of the RELAP5-3D run of an input deck, Pygi obtains the final conditions for each component. It creates a new input file that replaces the original input file values with updated conditions. This provides an accurate and efficient means of creating new input decks with steady-state input conditions. RGUI is an alternative to the command line interface for performing RELAP5-3D-related work. RGUI provides single-interface access to other RELAP5-3D tools such as Pygi. It is highly configurable, allowing the user to customize the environment. The interface runs on both Linux and Windows. This suite of utility programs is continually being enhanced to provide better support for RELAP5-3D users. This technical note provides details of Pygi and RGUI functionality. Future plans for enhancements are also included.

In order to evaluate the impact of these factors on the safety of the plant, the Risk-Informed Safety Margin Characterization (RISMC) pathway aims to provide insights to decision makers through a series of simulations of the plant dynamics for different initial conditions and accident scenarios. This paper presents a case study in order to show the capabilities of the RISMC methodology to assess the impact of power uprate of a boiling water reactor system during a station blackout accident scenario. We employ a system simulator code, RELAP5-3D, coupled with RA VEN, which performs the stochastic analysis. Our analysis is performed by (a) sampling values from a set of parameters from the uncertainty space of interest, (b) simulating the system behavior for that specific set of parameter values, and (c) analyzing the outcomes from the set of simulation runs.

It consists of several modules providing improved coupled core simulation capability: INSTANT (Intelligent Nodal and Semi-structured Treatment for Advanced Neutron Transport) (three-dimensional nodal transport core calculations); MRTAU (Multi-Reactor Transmutation Analysis Utility) (depletion and decay heat generation); and modules performing criticality searches, fuel shuffling, and generalized perturbation. Coupling of the PHISICS code suite to the thermal-hydraulic system code RELAP5-3D was finalized in 2013, and as part of the verification and validation effort, the first phase of the Organisation for Economic Co-operation and Development/Nuclear Energy Agency (OECD/NEA) MHTGR-350 benchmark has now been completed. The theoretical basis and latest development status of the coupled PHISICS/RELAP5-3D tool are described in more detail in a concurrent paper. This paper provides an overview of the OECD/NEA MHTGR-350 benchmark and presents the results of exercises 2 and 3 defined for phase I. Exercise 2 required the modeling of a stand-alone thermal fluids solution at the end of equilibrium cycle for the Modular High Temperature Gas-Cooled Reactor (MHTGR). The RELAP5-3D results of four subcases are discussed, consisting of various combinations of coolant bypass flows and material thermophysical properties. Exercise 3 required a coupled neutronics and thermal fluids solution, and the PHISICS/RELAP5-3D code suite was used to calculate the results of two subcases. The main focus of this paper is a comparison of results obtained with the traditional RELAP5-3D "ring" model approach against a much more detailed model that includes kinetics feedback on individual "block" level and thermal feedbacks on a triangular submesh. The higher fidelity that can be obtained by this block model is illustrated with comparison results on the temperature, power density, and flux distributions. It is shown that the ring model leads to significantly lower fuel temperatures (up to 10%) when compared with the higher-fidelity block model and that the additional model development and run-time efforts are worth the gains obtained in the improved spatial temperature and flux distributions.

The work presented here describes the ability of A. acidocaldarius to reduce the concentration of the phenolic compounds: phenol, ferulic acid, Ie-coumaric acid and sinapinic acid during growth conditions. The extent and rate of the removal of these compounds were significantly increased by the presence of micro-molar copper concentrations, suggesting activity by copper oxidases that have been identified in the genome of A. acidocaldarius. Substrate removal kinetics was first order for phenol, ferulic acid, Ie-coumaric acid and sinapinic acid in the presence of 50 mu M copper sulfate. In addition, laccase enzyme assays of cellular protein fractions suggested significant activity on a lignin analog between the temperatures of 45 and 90 degree C. This work shows the potential for A. acidocaldarius to degrade phenolic compounds, demonstrating potential relevance to biofuel production and other industrial processes.

Responsible and efficient use of the subsurface poses many challenges, many of which require the capability to monitor and manipulate sub-surface stress, fractures, and fluid flow at all scales. Adaptive control of subsurface fractures and flow is a multi-disciplinary challenge that, if achieved, has the potential to transform all subsurface energy strategies. As part of the U.S. Department of Energy's SubTER (Subsurface Technology and Engineering Research development and demonstration) initiative, a multi-National Laboratory team is developing next-generation approaches that will allow for adaptive control of subsurface fractures and flow. SubTER has identified an initial suite of technical thrust areas to focus work, and has initiated a number of small projects. This presentation will describe early progress associated with the SubTER technical topic areas of wellbore integrity, subsurface stress and induced seismicity, permeability manipulation and new subsurface signals. It will also describe SubTER plans, and provide a venue to solicit suggestions and discuss potential partnerships associated with future research directions.

The glacial chronology of Big Cottonwood Canyon, Wasatch Range, Utah is poorly understood, and has not been assessed since the early 1900's. We used a variety of modern techniques to establish new understanding of Late Pleistocene glaciation in Big Cottonwood and other Wasatch Range canyons. An absolute chronology was established through the use of cosmogenic nuclide (beryllium-10) exposure age dating; we processed seventeen samples from moraine boulders, erratics, and striated bedrock throughout Big Cottonwood Canyon. Remote mapping of glacial landforms was completed using 2-meter LiDAR digital elevation models, and all identified landforms later verified and mapped in the field. We then used a coupled energy-mass-balance and ice-flow model to 1. infer ice extents in Big Cottonwood Canyon, incorporating neighboring canyons with well constrained maxima; and 2. explore paleoclimate conditions during the Late Pleistocene necessary to reproduce these ice extents. Results reveal new information regarding the influence of Pleistocene Lake Bonneville on climate and landscape evolution in the Wasatch Range during and following the Last Glacial Maximum.

AN - 1815670715; 2016-075506 AB - To measure time-dependent deformation at the Raft River geothermal field in Cassia County in Southwestern Idaho, we analyze interferometric synthetic aperture radar (InSAR) data acquired between 2006 and 2015 by several satellite missions, including: Envisat, ALOS, TerraSAR-X, and TanDEM-X. The resulting time-series analysis indicates that the deformation began in late 2007, shortly after a 13-megawatt geothermal power plant began commercial production. The rate of deformation appears to be decreasing over time since 2008. The resulting maps of deformation show primarily uplift with some subsidence. The uplift signal is located in an approximately 8-km-by-5-km area centered near three injection wells that recycle produced brine into the Salt Lake formation, which consists of Miocene-Pliocene lacustrine deposits, volcanic tuffs, and lava flows. Subsidence occurs in an adjacent approximately 4-km-by-4-km area to the northwest. These two signatures remain in the same location in all of the well-correlated interferometric pairs since 2008. Although all production wells are also located inside the area experiencing uplift, most of them are close to the boundary that separates the two areas, and likely associated with the steeply dipping Bridge Fault zone. We explore the relative roles of thermal (T), and hydrological (H) processes on mechanical deformation (M).

The most common ash-analysis methods, such as inductively coupled plasma-optical emission spectrometry/mass spectrometry (ICP-OES/MS), require considerable time and expensive reagents. Laser-induced breakdown spectroscopy (LIBS) is emerging as a technique for rapid analysis of the inorganic constituents in a wide range of biomass materials. This study compares analytical results using LIBS data to results obtained from three separate ICP-OES/MS methods for 12 samples, including six standard reference materials. Analyzed elements include aluminum, calcium, iron, magnesium, manganese, phosphorus, potassium, sodium, and silicon, and results show that concentrations can be measured with an uncertainty of approximately 100 parts per million using univariate calibration models and relatively few calibration samples. These results indicate that the accuracy of LIBS is comparable to that of ICP-OES methods and indicate that some acid-digestion methods for ICP-OES may not be reliable for Na and Al. These results also demonstrate that germanium can be used as an internal standard to improve the reliability and accuracy of measuring many elements of interest, and that LIBS can be used for rapid determination of total ash in biomass samples. Key benefits of LIBS include little sample preparation, no reagent consumption, and the generation of meaningful analytical data instantaneously.

Application of the wave gradients in wave gradiometry additionally requires an accurate estimate of the wave field at the test location that is, in turn, subject to the same sources of noise, compounding inaccuracy in estimates of wave apparent velocity, amplitude changes, and direction. The spatial distribution of array elements can be controlled for a particular array design to yield potentially accurate spatial gradients. However, dense, large N arrays naturally alleviate problems with site statics, instrument calibration, and incoherent noise when the inverse problem is posed such that wave gradients and the wave field at the test location become the unknowns; both the wave gradients and test wave field become averages of the data over the array, reducing the effect of noise. A Taylor's series expansion of the wave field around any test point within the array becomes possible, even at those places that do not contain an array element. The resulting wave gradiometry parameters improve proportional to the number of array elements used. This method is used to examine the wave field using data from a 180 m x 300 m dense array associated with a 3D controlled source seismic experiment in southeastern Ohio demonstrating the complexity of the wavefield due to scattering in near-surface structure. The method is also used to analyze teleseismic P waves from the Long Beach, California, NodalSeismic array.

Modeling site effects is a fundamental step in the development of a site-specific seismic hazard curve and soil surface spectra in the seismic design of nuclear facilities. Five accelerometers have been installed near facilities at Idaho National Laboratory (INL) since 2013. A large number of ground motions from regional earthquakes (magnitudes 3.0 to 5.0) have been recorded, including the January 3, 2015, M5.0 Challis, ID, earthquake, providing a valuable dataset for studying site response at INL, especially wave propagation in a unique profile consisting of basalt that is fractured and interbedded with unconsolidated sediments. Previous site-response analyses conducted at INL have been based on one-dimensional (1D) equivalent-linear analysis using statistically generated soil profiles with shallow depths (up to 65 ft) (e.g., Payne and Costantino, 2003). While these analyses followed appropriate codes and standards for developing soil design spectra, they did not consider 1) representativeness of statistically generated soil velocity profiles, 2) the influence of strong velocity reversal below the elastic half-space boundary, and 3) two-dimensional (2D) or three-dimensional (3D) scattering effects due to sedimentary interbeds. The objective of this study is to investigate the significance of these issues using recent ground motion observations, with the ultimate goal of informing future site response and seismic hazard analyses. In this study, we first evaluate the effectiveness of the soil amplification function currently employed in seismic hazard analysis at INL by comparing it to the amplification observed from recorded ground motions. We then predict site response from alternative 1D models using measured shear wave velocity profiles with and without consideration of basalt-sediment sequence. Finally, we investigate scattering effects by using a numerical model which incorporates 3D heterogeneity of basalt and sedimentary interbeds. We observe that sedimentary interbeds can significantly reduce the amplification between 5 and 20 Hz, and the amplification function currently employed results in great conservatism.

While the conventional system is designed for high biomass yield areas, pilot scale operations have experienced feedstock supply shortages and price volatilities due to reduced harvests and competition from other industries. Regional supply dependency and the inability to actively manage feedstock stability and quality, provide operational risks to the biorefinery, which translate into higher investment risk. The advanced feedstock supply system based on a network of depots can mitigate many of these risks and enable wider supply system benefits. This paper compares the two concepts from a system-level perspective beyond mere logistic costs. It shows that while processing operations at the depot increase feedstock supply costs initially, they enable wider system benefits including supply risk reduction (leading to lower interest rates on loans), industry scale-up, conversion yield improvements, and reduced handling equipment and storage costs at the biorefinery. When translating these benefits into cost reductions per liter of gasoline equivalent (LGE), we find that total cost reductions between -$0.46 to -$0.21 per LGE for biochemical and -$0.32 to -$0.12 per LGE for thermochemical conversion pathways are possible. Naturally, these system level benefits will differ between individual actors along the feedstock supply chain. Further research is required with respect to depot sizing, location, and ownership structures. Published 2015. This article is a U.S. Government work and is in the public domain in the USA.

At each time step, a lower-upper symmetric Gauss-Seidel preconditioned generalized minimal residual solver is used to solve the systems of linear equations arising from an explicit first stage, single diagonal coefficient, diagonally implicit Runge-Kutta time integration scheme. The performance of the developed method is assessed through a variety of unsteady flow problems. Numerical results indicate that this method is able to deliver the designed third-order accuracy of convergence in both space and time, while requiring remarkably less storage than the standard third-order discontinous Galerkin methods, and less computing time than the lower-order discontinous Galerkin methods to achieve the same level of temporal accuracy for computing unsteady flow problems.

The existing methods are complicated and expensive, or have a low probability of success. Herein, we report a modified methodology for preparation of TEM samples from powders, which is efficient, cost-effective, and easy to perform. This method involves mixing powders with an epoxy on a piece of weighing paper, curing the powder-epoxy mixture to form a bulk material, grinding the bulk to obtain a thin foil, punching TEM discs from the foil, dimpling the discs, and ion milling the dimpled discs to electron transparency. Compared with the well established and robust grinding-dimpling-ion-milling method for TEM sample preparation for bulk materials, our modified approach for preparing TEM samples from powders only requires two additional simple steps. In this article, step-by-step procedures for our methodology are described in detail, and important strategies to ensure success are elucidated. Our methodology has been applied successfully for preparing TEM samples with large thin areas and high quality for many different mechanically milled metallic powders.

The release of this energy during a fault condition could produce arcs that can damage the magnets of these systems. The public safety consequences of such events must be explored for a DEMO reactor because the magnets are located near the DEMO primary radioactive confinement barrier, the reactor's vacuum vessel (VV). Great care will be taken in the design of DEMO's magnet systems to detect and provide a rapid field energy dump to avoid any accidents conditions. During an event when a fault condition proceeds undetected, the potential of producing melting of the magnet exists. If molten material from the magnet impinges on the walls of the VV, these walls could fail, resulting in a pathway for release of radioactive material from the VV. A model is under development at Idaho National Laboratory (INL) called MAGARC to investigate the consequences of this accident in a large toroidal field (TF) coil. Recent improvements to this model are described in this paper, along with predictions for a DEMO relevant event in a toroidal field magnet.

Soil samples taken in the early 1970's near a Department of Energy radioactive waste disposal site (the Subsurface Disposal Area, SDA, located in southeastern Idaho) provide a case study for studying the mechanisms and characteristics of environmental actinide and (super 137) Cs transport in an arid environment. Multi-component mixing models suggest actinide contamination within 2.5 km of the SDA can be described by mixing between 2 distinct SDA end members and regional nuclear weapons fallout. The absence of chemical fractionation between (super 241) Am and (super 239+240) Pu with depth for samples beyond the northeastern corner and lack of (super 241) Am in-growth over time (due to (super 241) Pu decay) suggest mechanical transport and mixing of discrete contaminated particles under arid conditions. Occasional samples northeast of the SDA (the direction of the prevailing winds) contain anomalously high concentrations of Pu with (super 240) Pu/ (super 239) Pu isotopic ratios statistically identical to those in the northeastern corner. Taken together, these data suggest flooding resulted in mechanical transport of contaminated particles into the area between the SDA and a flood containment dike in the northeastern corner, following which subsequent contamination spreading in the northeastern direction resulted from wind transport of discrete particles.

Silver behavior was dominated by rapid release of an appreciable fraction of the compact inventory (3-34%) at the beginning of the tests, believed to be from inventory residing in the compact matrix and outer pyrocarbon (OPyC) prior to the safety test. Measurable release of silver from intact particles appears to become apparent only after ~60 h at 1800 [degrees]C. The release rate for europium and strontium was nearly constant for 300 h at 1600 [degrees]C (reaching maximum values of approximately 2 x 10 super(-3) and 8 x 10 super(-4) respectively), and at this temperature the release may be mostly limited to inventory in the compact matrix and OPyC prior to the safety test. The release rate for both elements increased after approximately 120 h at 1800 [degrees]C, possibly indicating additional measurable release through the intact particle coatings. Cesium fractional release from particles with intact coatings was <10 super(-6) after 300 h at 1600 [degrees]C or 100 h at 1800 [degrees]C, but release from the rare particles that experienced SiC failure during the test could be significant. However, Kr release was still very low for 300 h 1600 [degrees]C (<2 x 10 super(-6)). At 1800 [degrees]C, krypton release increased noticeably after SiC failure, reflecting transport through the intact outer pyrocarbon layer. Nonetheless, the krypton and cesium release fractions remained less than approximately 10 super(-3) after 277 h at 1800 [degrees]C.

The result shows a high thermal stability of the fission gas bubble superlattice. The implication of this observation on the fuel microstructural evolution and performance under irradiation is discussed.

Therefore, understanding of fuel-cladding interaction (FCCI) is critical for evaluation of fuel performance in a reactor environment. In this contribution, phases formed between U-22Pu-4Mo and U-25Pu-15Mo (in wt%) fuel alloys and Fe-12Cr cladding were characterized using scanning and transmission electron microscopy (SEM/TEM) techniques. Phases formed within FCCI layers in both alloys were identified by implementing selective area diffraction pattern analysis as Cr sub(0.3)Mo sub(0.7) (Im-3m), Fe sub(2)U (Fd-3m), UCrFe (Fd-3m), and Fe sub(2)Pu (Fd-3m). Phases formed at the end of the FCCI layer in the U-22Pu-4Mo alloy included UCrFe (Fd-3m), Fe sub(2)U (Fd-3m), and Cr sub(2)FeO sub(4) (Fd-3m) while in the U-25Pu-15Mo alloy the phases were consistent with Cr sub(0.49)Fe sub(0.51) (P4 sub(2)/mnm), Cr sub(0.8)Fe sub(0.2) (Im-3m), and UCrFe (Fd-3m).

AN - 1702651389; 25926141 AB - OBJECTIVESSearching for more effective and selective therapies for head and neck cancer, we demonstrated the therapeutic effect of boron neutron capture therapy (BNCT) to treat oral cancer and inhibit long-term tumor development from field-cancerized tissue in the hamster cheek pouch model. However, BNCT-induced mucositis in field-cancerized tissue was dose limiting. In a clinical scenario, oral mucositis affects patients' treatment and quality of life. Our aim was to evaluate different radioprotectors, seeking to reduce the incidence of BNCT-induced severe mucositis in field-cancerized tissue.MATERIALS AND METHODSCancerized pouches treated with BNCT mediated by boronophenylalanine at 5 Gy were treated as follows: control: saline solution; Hishigh : histamine 5 mg kg(-1) ; Hislow : histamine 1 mg kg(-1) ; and JNJ7777120: 10 mg kg(-1).RESULTSHislow reduced the incidence of severe mucositis in field-cancerized tissue to 17% vsCONTROL55%; Hishigh : 67%; JNJ7777120: 57%. Hislow was non-toxic and did not compromise the long-term therapeutic effect of BNCT or alter gross boron concentration.CONCLUSIONHistamine reduces BNCT-induced mucositis in experimental oral precancer without jeopardizing therapeutic efficacy. The fact that both histamine and boronophenylalanine are approved for use in humans bridges the gap between experimental work and potential clinical application to reduce BNCT-induced radiotoxicity in patients with head and neck cancer.

Primary and other loops in multiple coolant loop systems in nuclear power plants can be modeled in nuclear system codes, such as Reactor Excursion and Leak Analysis Program (RELAP5), COBRA-TRAC, TRACE, and ATHLET, for the interaction and feedback effects between the coolant loops. This article proposes a new coupling between a system code and Laboratory Virtual Instrument Engineering Workbench (LARVIEW) in a unique framework (called as Modeling of Coolant Systems with a Unique Framework -MCUF-) that allows integrating an experimental apparatus or a facility to a whole power plant model. The results of the coupling have been compared with the typical RELAP5 results which significantly depend on "hard coded" data for second coolant loop.

The present study includes understanding the effect of feedstock moisture in the range of 28-38% (wet basis [w.b.]) and preheating in the range of 30-110 degree C at two die speeds of 40 and 60 Hz on the physical properties and SEC. A flat die pellet mill fitted with a 6 mm die was used in the present study. The physical properties of pellets such as moisture content, unit, bulk and tapped density, durability, and expansion ratio and SEC of the pelleting process are measured. The results indicate that the pellets produced have durability values in the range of 87-98%, and unit bulk and tapped density in the range of 670-1100, 375-575, and 420-620 kg/m super(3). Increasing the feedstock moisture content from 33% to 38% (w.b) decreased the unit, bulk and tapped density by about 30-40%. Increasing feedstock moisture content increased the expansion ratio and decreased the density values. A higher feedstock moisture content of 38% (w.b.) and higher preheating temperature of 110 degree C resulted in lower density and a higher expansion ratio, which can be attributed to flash off of moisture as the material extrudes out of the die. The SEC was in the range of 75-275 kWh/ton. Higher feedstock moisture content of 38% (w.b.) and a lower die speed of 40 Hz increased the SEC, whereas lower to medium preheating temperature (30-70 degree C), medium feedstock moisture content of 33% (w.b.), and a higher die speed of 60 Hz minimized the SEC to <100 kWh/ton. Corn stover pellets produced in a flat die pellet mill fitted with 6 mm die at feedstock moisture content of 33% (w.b.) and at two different die speeds (40 & 60 Hz) and preheating temperatures (70 & 110 degree C).

PQ0001610971 AB - The objective of this study was to examine the relationship between slip, trip and fall injuries and obesity in a population of workers at the Idaho National Laboratory (INL) in Idaho Falls, Idaho. INL is an applied engineering facility dedicated to supporting the US Department of Energy's mission. An analysis was performed on injuries reported to the INL Medical Clinic to determine whether obesity was related to an increase in slip, trip and fall injuries. Records were analysed that spanned a 6-year period (2005-2010), and included 8581 employees (mean age, 47 plus or minus 11 years and body mass index [BMI], 29 plus or minus 5 kg/m super(2); 34% obesity rate). Of the 189 people who reported slip, trip and fall injuries (mean age, 48 plus or minus 11 years), 51% were obese (P < 0.001 compared with uninjured employees), and their mean BMI was 31 plus or minus 6 kg/m super(2) (P < 0.001). Obesity in this population was associated with a greater rate of slip, trip and fall injuries. Practitioner Summary: Slip, trip and fall injuries are a major contributor of workplace-related injuries and a great financial burden to employers. This study examines the impact of obesity in slip, trip and fall injuries. The investigation found that obesity was associated with a greater rate of slip, trip and fall injuries.

The method treats the solution variables of interest (that can be located at cell centers, cell edges, or cell nodes) implicitly and the rest of the information related to same or other variables are handled explicitly. The method does not require implicit iteration; instead it time advances the solutions in a similar spirit to explicit methods, except it involves a few additional function(s) evaluation steps. Moreover, the method is unconditionally stable, as a fully implicit method would be. This new approach exhibits the simplicity of implementation of explicit methods and the stability of implicit methods. It is specifically designed for slow transient flow problems of long duration wherein one would like to perform time integrations with very large time steps. Because the method can be time inaccurate for fast transient problems, particularly with larger time steps, an appropriate solution strategy for a problem that evolves from a fast to a slow transient would be to integrate the fast transient with an explicit or semi-implicit technique and then switch to this point implicit method as soon as the time variation slows sufficiently. We have solved several test problems that result from scalar or systems of flow equations. Our findings indicate the new method can integrate slow transient problems very efficiently; and its implementation is very robust.

Recently, advanced characterization techniques have been used to examine fuel particles from the Idaho National Laboratory's AGR-1 experiment. Nano-sized Ag and Pd precipitates were previously identified in grain boundaries and triple points in the SiC layer of irradiated TRISO nuclear fuel. Continuation of this initial research is reported in this paper and consists of the characterization of a relatively large number of nano-sized precipitates in three areas of the SiC layer of a single irradiated TRISO nuclear fuel particle using standardless EDS analysis on focused ion beam-prepared transmission electron microscopy samples. Composition and distribution analyses of these precipitates, which were located on grain boundaries, triple junctions and intragranular precipitates, revealed low levels, generally <10 atomic %, of palladium, silver and/or uranium with palladium being the most common element found. Palladium by itself, or associated with either silver or uranium, was found throughout the SiC layer. A small number of precipitates on grain boundaries and triple junctions were found to contain only silver or silver in association with palladium while uranium was always associated with palladium but never found by itself or in association with silver. Intergranular precipitates containing uranium were found to have migrated ~23 mu m along a radial direction through the 35 mu m thick SiC coating during the AGR-1 experiment while silver-containing intergranular precipitates were found at depths up to ~24 mu m in the SiC layer. Also, Pd-rich, nano-precipitates (~10 nm in diameter), without evidence for the presence of either Ag or U, were revealed in intragranular regions throughout the SiC layer. Because not all grain boundaries and triple junctions contained precipitates with fission products and/or uranium, along with the differences in migration behavior between Pd, Ag and U, it was concluded that crystallographic grain boundary and triple junction parameters likely influence migration behavior.

In this fuel design, a thin layer of zirconium is used to eliminate the direct interaction between the U-Mo fuel meat and the aluminum-alloy cladding during irradiation. The co-rolling process used to bond the Zr barrier layer to the U-Mo foil during fabrication alters the microstructure of both the U-10Mo fuel meat and the U-Mo/Zr interface. This work studied the effects of post-rolling annealing treatment on the microstructure of the co-rolled U-Mo fuel meat and the U-Mo/Zr interaction layer. Microscopic characterization shows that the grain size of U-Mo fuel meat increases with the annealing temperature, as expected. The grain sizes were ~9, ~13, and ~20 mu n for annealing temperature of 650, 750, and 850 [degrees]C, respectively. No abnormal grain growth was observed. The U-Mo/Zr interaction-layer thickness increased with the annealing temperature with an Arrhenius constant for growth of 184 kJ/mole, consistent with a previous diffusion-couple study. The interaction layer thickness was 3.2 + or -0.5 mu n, 11.1 + or -2.1 mu n, 27.1 + or -0.9 mu n for annealing temperature of 650, 750, to 850 [degrees]C, respectively. The homogeneity of Mo improves with post rolling annealing temperature and with U-Mo coupon homogenization. The phases in the Zr/U-Mo interaction layer produced by co-rolling, however, differ from those reported in the previous diffusion couple studies.

These codes are able to predict pressure drop, void fraction distributions and temperature distributions for various coolants, heated flow geometries, and heat configurations. They also include models for various two-phase flow regimes, but extreme flow conditions that involve significant phase change can tax the current code capabilities. Current system codes have mass, momentum, and energy conservation equations for two fields (liquid and vapor), resulting in a model with six conservation equations. Recent developments in limited applications of a few of these codes have added a separate droplet field from the continuous liquid. This is part of a trend toward the inclusion of more fields (and requisite conservation equations) in system codes. The representation of two phase flow phenomena is improved by increasing the number of fields.

Oil shale is an organic-rich fine-grained sedimentary rock that contains significant amounts of kerogen from which liquid hydrocarbons can be produced. Water is needed to retort or extract oil shale at an approximate rate of three volumes of water for every volume of oil produced. Concerns have been raised over the demand and availability of water to produce oil shale, particularly in semiarid regions where water consumption must be limited and optimized to meet demands from other sectors. The economic benefit of oil shale development in this region may have tradeoffs within the local and regional environment. Due to these potential environmental impacts of oil shale development, water usage issues need to be further studied. A basin-wide baseline for oil shale and water resource data is the foundation of the study. This paper focuses on the design and construction of a centralized geospatial infrastructure for managing a large amount of oil shale and water resource related baseline data, and for setting up the frameworks for analytical and numerical models including but not limited to three-dimensional (3D) geologic, energy resource development systems, and surface water models. Such a centralized geospatial infrastructure made it possible to directly generate model inputs from the same database and to indirectly couple the different models through inputs/outputs. Thus ensures consistency of analyses conducted by researchers from different institutions, and help decision makers to balance water budget based on the spatial distribution of the oil shale and water resources, and the spatial variations of geologic, topographic, and hydrogeological characterization of the basin. This endeavor encountered many technical challenging and has not been done in the past for any oil shale basin. The database built during this study remains valuable for any other future studies involving oil shale and water resource management in the Piceance Basin. The methodology applied in the development of the GIS based geospatial infrastructure can be readily adapted for other professionals to develop database structure for other similar basins.

Given the known efficiency, the assumption could be made that the air concentrations of radioactivity measured outside the structure would be proportional to the air concentrations measured inside the structure. To investigate this assumption, the inside concentration data was compared with the outside concentration data. The correlation of the data suggested that the inside concentrations were not a good predictor of the outside concentrations. This poor correlation was deemed to be a result of operational unknowns within the structures.

The ZrN serves as a diffusion barrier to eliminate a deleterious reaction that can occur between U-7Mo and Al when a dispersion fuel is irradiated under aggressive reactor conditions. To investigate the final microstructure of a physically-vapor-deposited ZrN coating in a dispersion fuel plate after it was fabricated using a rolling process, characterization samples were taken from a fuel plate that was fabricated at 500[degrees]C using ZrN-coated U-7Mo particles, Al matrix and AA6061 cladding. A relatively high level of oxygen was observed in the ZrN coating, extending from the Al matrix in the ZrN coating in decreasing concentration. The above microstructural characteristics are discussed in terms of what may be most optimal for a diffusion barrier in a dispersion fuel plate application.

The bubble superlattice was seen to form a face centered cubic structure coherent with the host U-7 wt%Mo body-centered cubic structure. At a fission density between 3.0 and 4.5 x 10 super(21) fiss/cm super(3), the superlattice bubbles appear to have reached a saturation size with additional fission gas associated with increasing bumup predominately accumulating along grain boundaries. At a fission density of ~4.5 x 10 super(21) fiss/cm super(3), the U-7 wt%Mo microstructure starts to undergo grain subdivision and can no longer support the ordered bubble superlattice. The sub-divided fuel grains are less than 500 nm in diameter with what appears to be micron-size fission-gas bubbles present on the grain boundaries. Solid fission products typically decorate the inside surface of the micron-sized fission-gas bubbles. Residual superlattice bubbles are seen in areas where fuel grains remain micron sized. Potential mechanisms of the formation and collapse of the bubble superlattice are discussed.

Analysis of variance indicated that briquette moisture content and initial density immediately after compaction and final density after 2 weeks of storage are strong functions of feedstock moisture content and compression pressure, whereas durability rating is influenced by die temperature and feedstock moisture content. Briquettes produced at a low feedstock moisture content of 9 % (w.b.) yielded maximum densities >700 kg/m super(3) for wheat, oat, canola, and barley straws. Lower feedstock moisture content of 110 degree C and compression pressure >10 MPa minimized the briquette moisture content and maximized densities and durability rating based on surface plots observations. Optimal process conditions indicated that a low feedstock moisture content of about 9 % (w.b.), high die temperature of 120-130 degree C, medium-to-large hammer mill screen sizes of about 24 to 31.75 mm, and low to high compression pressures of 7.5 to 12.5 MPa minimized briquette moisture content to 700 kg/m super(3). Durability rating >90 % is achievable at higher die temperatures of >123 degree C, lower to medium feedstock moisture contents of 9 to 12 % (w.b.), low to high compression pressures of 7.5 to 12.5 MPa, and large hammer mill screen size of 31.75 mm, except for canola where a lower compression pressure of 7.5 to 8.5 MPa and a smaller hammer mill screen size of 19 mm for oat maximized the durability rating values.

Field studies have shown that surface and cross-borehole electrical resistivity tomography (ERT) can be a useful tool in imaging and characterizing solute transport in heterogeneous subsurface. In this synthetic study, we have coupled a 3-D multiphase flow model with a parallel 3-D time-lapse ERT inversion code to explore the feasibility of using time-lapse ERT for simultaneously monitoring the migration of CO (sub 2) plume in deep saline formation and potential brine intrusion into shallow fresh water aquifer. Direct comparisons of the inverted CO (sub 2) plumes resulting from ERT with multiphase flow simulation results indicate the ERT could be used to delineate the migration of CO (sub 2) plume. Detailed comparisons on the locations, sizes and shapes of CO (sub 2) plume and intruded brine plumes suggest that ERT inversion tends to underestimate the area review of the CO (sub 2) plume, but overestimate the thickness and total volume of the CO (sub 2) plume. The total volume of intruded brine plumes is overestimated as well. However, all discrepancies remain within reasonable ranges. Our study suggests that time-lapse ERT is a useful monitoring tool in characterizing the movement of injected CO (sub 2) into deep saline aquifer and detecting potential brine intrusion under large-scale field injection conditions.

The method utilizes the solidilication characteristics of the uranium products to determine zirconium levels based on standard cooling curve analyses and established binary phase diagram data. Numerous uranium products have been analyzed for their zirconium content and compared against measured zirconium data. From this data, the following equation was derived for the zirconium content of uranium products: Zr = 0.14M + 131.56 - 12.63(348.65 - 0.16LT) super(1/2) where M is the mass (kg) of the ingot and LT is the liquidus temperature (K) found by cooling curve analyses. Based on this equation, a reasonable fit of calculated to measured zirconium content was established considering the errors in the system.

If deployed, these conceptual systems could lead to more efficient utilization of clean energy generation sources, including renewable and nuclear options, to meet both grid demand and thermal energy needs in the industrial sector. One such concept - referred to as a "hybrid" energy system (HES) - is tighter coupling of nuclear and renewable energy sources in a manner that better optimizes energy use for the combined electricity, industrial manufacturing, and transportation sectors. The integrated energy system would be capable of dynamically apportioning thermal and electrical energy to first meet the grid demand (with appropriate power conversion systems), then utilizing excess thermal and, in some cases, electrical energy to drive a process that results in an additional product.

Several geophysical and hydrological studies of the NCV occurred during the 1970's motivated by the presence of thermal wells and springs in the area, culminating with geothermal exploration wells drilled by Sunedco Energy Development. The test borehole temperatures were deemed too low for power production using technology available at that time (test hole temperatures <120 degrees C). In January of 2014, a water well drilled to 79 meters, encountered Na-Cl-HCO (sub 3) water with a measured bottom hole temperature of 104 degrees C. Traditional magnesium corrected Na-K-Ca geothermometry of water from that well estimated the temperature of the thermal reservoir to be 204 degrees C. Inspired by this revived interest, new studies utilizing updated geochemical and geophysical techniques are currently under way. Present understanding of the NCV geothermal system suggests that fluid flow is associated with a fault(s) adjacent to Little Mountain - a small secondary horst complex within the primary Cache Valley graben. The existing data from the area is relatively sparse and is not suitable for pinpointing the location of faults thought to carry thermal water from depth to the near surface. To accurately characterize the plumbing of the geothermal system, lines of closely spaced potential field (gravity and magnetic) measurements were performed across the suspected location of the Little Mountain bounding faults. Analysis of these data in conjunction with existing hydrogeologic and geochemistry data will aid in determining fault locations carrying thermal fluid to shallow depths. Future work proposed to better characterize the geothermal system includes thermal imaging, utilizing an unmanned aerial vehicle (UAV), to detect elevated ground surface temperatures thought to exist based on preferential snow melt in the area.

Data that could be obtained from a transient testing program would be used to support advanced reactor designs and validate computational predictions of fuel and core behavior. Such validation will be an important factor for U.S. Nuclear Regulatory Commission (NRC) review and approval of next generation power reactor design and safety evaluations [2]. In support of this mission, the Transient Reactor Experiment and Test Facility (TREAT) is being reactivated by DOE-NE, following an extended outage, to support transient fuel performance research and safety testing.

The ATF program supports research into the concept development, fabrication, irradiation performance evaluation and accident environment testing of a number of candidate fuels for the replacement of the existing fuels used in the current light water power reactor (LWR) fleet and future power reactors [1]. The candidate fuel concepts under investigation by the ATF program include several advanced cladding concepts used in conjunction with both traditional ceramic (UO sub(2)) fuel pellets and advanced composite fuel pellets such as UN-U sub(3)Si sub(2). Similarly, some fuel concepts that are under investigation are examining the use of traditional cladding materials such as Zircaloy in conjunction with advanced composite fuel pellet designs that may provide enhanced safety performance under accident conditions such as their exposure to high temperatures and steam such as those experienced under Reactivity Initiated Accidents (RIA) and Loss of Coolant Accidents (LOCA). Overall, these fuel concepts aim to improve their reaction kinetics with steam in order to reduce oxidation of claddings and hydrogen production, minimize Fuel to Cladding Mechanical Interactions (FCMI) and Fuel to Cladding Chemical Interactions (FCCI), and improve fission product retention under these credible accident conditions [2].

Generally, this design is effective in preventing significant release of most fission products. However, irradiation experiments in the U.S. and Europe, over the past 40 years have documented the release of silver in spite of no apparent failure of the SiC layer of TRISO fuel particles [1,2]. A considerable amount of research has attempted to understand the mechanism of fission product migration through intact SiC layers (for reviews, see [3,4]). Although none have been definitively shown to be responsible for fission product migration in TRISO fuel under expected operating conditions, the most viable migration mechanisms rely on migration of fission products along grain boundaries.

Among various sources of GHG, the global electricity supply sector generates the largest share of GHG emissions (37.5% of total CO sub(2) emissions) [2].

The model replicates the geometry of a one-third scale HLW melter used for testing at the VSL. The model provides a platform to incorporate additional physics and study the effects of changing various parameters, such as glass composition, bubbler configuration, etc. Future work includes evaluating data from experiments on bubbling in glasses and other high viscosity liquids and incorporating a rigorous sub-model for bubble behavior. Improvements and additional physics based upon laboratory data are continually being added to the cold cap model [11]. Updates to the cold cap model will be incorporated to the CFD model as they become available. Once all of the pertinent physics has been added to the model, validation of the computational predictions will be performed.

Accurate modeling and simulation of two-phase flow are critical to the safety analyses of nuclear reactors. Several nuclear reactor system analysis codes have been developed to solve the simplified one-dimensional two-phase flow equations to represent the complex reactor systems. These codes, such as RELAP5 [1-2] and TRAC [3], have gained great successes in supporting reactor safety analyses, as well as design and licensing of new reactors.

Strict numerical verification works for a single phase natural circulation loop simulation with the RELAP-7 code have been performed. Second order convergence rates for both time and space are confirmed with selected figure of merits. For a fully implicit code like RELAP-7, although the time step and grid size are not limited by stability requirement, the numerical errors may limit their sizes. Numerical verification can tell users the proper sizes of time step and grid for different types of problems.

A motivation for this need is to support current research and development activities underway that are seeking to create new accident-tolerant nuclear fuels. A second motivation is to support the collection of benchmark and validation data to support the development of new meso-scale simulation codes that are needed to design, understand, and qualify new fuel concepts. The first steps of the hodoscope refurbishment program are limited in scope to reduce risk and ensure the operational capability will be ready for when it is needed. Beyond these near term requirements, there may be opportunists to develop wholly-new methods for monitoring the performance of nuclear fuel during transient conditions.

TREAT is an air-cooled, thermal-spectrum test facility designed to evaluate reactor fuels and structural materials under simulated nuclear excursions and transient power/cooling mismatch situations in a nuclear reactor [1]. Operating from February 1959 until April 1994, the TREAT facility was specifically built to conduct transient reactor tests where the test material is subjected to neutron pulses that can simulate conditions ranging from mild upsets to severe reactor accidents. The reactor was constructed to test fast reactor fuels, but has also been used for light water reactor fuel testing as well as other exotic special purpose fuels. [2, 3] TREAT has not operated since 1994 but has been maintained in a standby mode.

In this study we present the geochemical and isotopic results of reservoir fluids and dissolved gases from the Mississippian Madison Limestone and Pennsylvanian Weber Sandstone from a potential CCUS target on the Rock Springs Uplift in southwestern Wyoming. Results are used to evaluate brine evolution, predict geochemical fluid reactions in response to CO (sub 2) injection and well completion practices, and investigate stacked reservoir confinement. The brines are Na-Cl type with total dissolved solid concentrations in excess of 85,000 mg/L. Conservative analyses indicate that the evolution of the brines in both formations have been heavily influenced by evaporite dissolution, increasing the molar ratio of Br-Na-Cl. Dolomitization at depth in each reservoir results in magnesium depletion. Comparative analysis suggests that dissolution of evaporite and other minerals has had a large influence on the evolution of the formation fluids. This has resulted in increased TDS post-burial, resulting in some of the most saline formation fluids collected in Wyoming. Simulations of CO (sub 2) injection into the formation brines suggest a decrease in pH, resulting in CaCO (sub 3) dissolution and CaSO (sub 4) precipitation. These reactions could cause an increase in porosity of 1% to 3%, and increase the viability of storage. We also note significant changes to molar ratios of Br-Na-Cl, and the concentrations of HCO (sub 3) , SO4 and volatile organic compounds before and after work over in the well-bore. The differences of solute concentrations between samples sets could be attributable to different collection methods, but are more likely recording changes to the formation fluid from work-over practices in the well-bore. The isotopic compositions of fluids and dissolved gases were found to be unique to each formation. Rare earth element concentrations further establish distinctive fluid concentrations. Though these fluids share a similar evolution, we suggest that dissimilarities in the isotopic compositions of the brines, dissolved gases and rare earth element concentrations indicate that the target formation fluids are isolated from each other.

Tungsten samples were exposed to neutrons in the High Flux Isotope Reactor (HF1R) at Oak Ridge National Laboratory and damaged to 0.025 and 0.3 dpa. Subsequently, they were exposed to deuterium plasmas in the Tritium Plasma Experiment (TPE) at Idaho National Laboratory. The implanted deuterium was desorbed through sample heating to 900 [degrees]C, and Doppler broadening (DB)-PAS was performed both before and after heating. Results show that deuterium impregnated tungsten is identified as having a smaller S-parameter. The S-parameter increases after deuterium desorption. Microstructural changes also occur during sample heating. These effects can be isolated from deuterium desorption by comparing the S-parameters from the deuterium-free back face with the deuterium-implanted front face. The application of using DB-PAS to examine deuterium retention in tungsten is examined.

Subsequently, thermal desorption spectroscopy was performed with a ramp rate of 10 [degrees]C min super(-1) up to 900 [degrees]C, and the samples were annealed at 900 [degrees]C for 0.5 h. These procedures were repeated three times to uncover defect-annealing effects on deuterium retention. The results show that deuterium retention decreases approximately 70% for at 500 [degrees]C after each annealing, and radiation damages were not annealed out completely even after the 3rd annealing. TMAP modeling revealed the trap concentration decreases approximately 80% after each annealing at 900 [degrees]C for 0.5 h.

Through the integration of BISON with the DAKOTA software, a sensitivity analysis of the results to selected model parameters is carried out based on UO sub(2) single-pellet simulations covering different power regimes. The parameters are varied within ranges representative of the relative uncertainties and consistent with the information in the open literature. The study leads to an initial quantitative assessment of the uncertainty in fission gas behavior predictions with the parameter characterization presently available. Also, the relative importance of the single parameters is evaluated. Moreover, a sensitivity analysis is carried out based on simulations of a fuel rod irradiation experiment, pointing out a significant impact of the considered uncertainties on the calculated fission gas release and cladding diametral strain. The results of the study indicate that the commonly accepted deviation between calculated and measured fission gas release by a factor of 2 approximately corresponds to the inherent modeling uncertainty at high fission gas release. Nevertheless, significantly higher deviations may be expected for values around 10% and lower. Implications are discussed in terms of directions of research for the improved modeling of fission gas behavior for engineering purposes.

T. Mihalczo (team leader), J. J. Lynn, and J. R. Taylor performed experiments at the Oak Ridge Critical Experiments Facility with highly enriched uranium (HEU) metal (called Oak Ridge Alloy or ORALLOY) in an effort to recreate GODIVA I results with greater accuracy than those performed at Los Alamos National Laboratory in the 1950s. The purpose of the Oak Ridge ORALLOY Sphere experiments was to estimate the unreflected and unmoderated critical mass of an idealized sphere of uranium metal corrected to a density, purity, and enrichment such that it could be compared with the GODIVA I experiments. Additionally, various material reactivity worths, the surface material worth coefficient, the delayed neutron fraction, the prompt neutron decay constant, relative fission density, and relative neutron importance were all measured. The critical assembly, material reactivity worths, the surface material worth coefficient, and the delayed neutron fraction were all evaluated as benchmark experiment measurements. The reactor physics measurements are the focus of this paper; although for clarity the critical assembly benchmark specifications are briefly discussed.

Initial experiments, performed in November and December 1962, consisted of a core of unmoderated stainless steel tubes surrounded by a graphite reflector. Later experiments included beryllium-reflected assemblies with the fuel in a 1.506-cm triangular lattice and in seven-tube clusters. Once the critical configurations had been achieved, various measurements of reactivity, relative axial and radial activation rates of super(2)35 super(,) and cadmium ratios were performed. The critical configurations, the cadmium ratio, and activation rate measurements for the beryllium-reflected 1,506-cm-array critical configuration have been evaluated and are described in this paper.

Experiments include criticality, control rod worth measurements, shutdown margin, and excess reactivity for four core loadings with 56, 60, 62, and 64 fuel elements. The worths of four graphite reflector block assemblies and an empty dry tube used for experiment irradiations were also measured and evaluated for the 60-fuel-element core configuration. Dominant uncertainties in the experimental k sub(e)ffcome from uncertainties in the manganese content and impurities in the stainless steel fuel cladding as well as the super(236)U and erbium poison content in the fuel matrix. Calculations with MCNP5 (Monte Carlo N-Particle version 5-1.60) and ENDF/B-VII.0 neutron nuclear data are ~1.4% (9[sigma]) greater than the benchmark model eigenvalues, which is commonly seen in Monte Carlo simulations of other TRIGA (Training, Research, Isotopes, General Atomics) reactors. Simulations of the worth measurements are within the 2[sigma] uncertainty for most of the benchmark experiment worth values.

The hydrological inputs to groundwater models can be numerous and can vary in both time and space. Difficulties associated with model construction are often related to extensive datasets and cumbersome data processing tasks. To mitigate these difficulties, a graphical user interface (GUI) is often employed to aid the input of data for creating models. Unfortunately, GUI software presents an obstacle to reproducibility, a cornerstone of research. The considerable effort required to document processing steps in a GUI program, and the rapid obsoleteness of these steps with subsequent versions of the software, has prompted modelers to explicitly write down processing steps as source code to make them 'easily' reproducible. This research describes the R package wrv, a collection of datasets and functions for pre- and post-processing the numerical groundwater flow model of the Wood River Valley aquifer system, south-central Idaho. R largely facilitates reproducible modeling with the package vignette; a document that is a combination of content and source code. The code is run when the vignette is built, and all data analysis output (such as figures and tables) is created on the fly and inserted into the final document. The wrv package includes two vignettes that explain and run steps that (1) create package datasets from raw data files located on a publicly accessible repository, and (2) create and run the groundwater flow model. MODFLOW-USG, the numerical groundwater model used in this study, is executed from the vignette, and model output is returned for exploratory analyses. The ability of R to perform all processing steps in a single workflow is attributed to its comprehensive list of features; that include geographic information system and time series functionality.

In this study we apply a coupled 2-d mass/energy balance and flow model (Plummer and Phillips, 2003) to reconstruct local last glacial maximum (LLGM) glaciers and paleoclimate in ten study areas along the crest of the U.S. Rocky Mountains between 33 degrees N and 49 degrees N. In some of the areas, where timing of post-LLGM ice recession is constrained by surface exposure ages on either polished bedrock upvalley from the LLGM moraines or post-LLGM recessional moraines, we use the model to assess magnitudes and rates of climate change during deglaciation. The modeling reveals a complex pattern of LLGM climate. The magnitude of LLGM-to-modern climate change (temperature and/or precipitation change) was greater in both the northern (Montana) Rocky Mountains and southern (New Mexico) Rocky Mountains than in the middle (Wyoming and Colorado) Rocky Mountains. We use temperature depression estimates from global and regional climate models to infer LLGM precipitation from our glacier model results. Our results suggest a reduction of precipitation coupled with strongly depressed temperatures in the north, contrasted with strongly enhanced precipitation and much more modest temperature depression in the south. The middle Rocky Mountains of Colorado and Wyoming appear to have experienced a reduction in precipitation at the LLGM without the strong temperature depression of the northern Rocky Mountains. Preliminary work on modeling of deglaciation in the Sangre de Cristo Range in southern Colorado suggests that approximately half of the LLGM-to-modern climate change took place during the initial approximately 2400 years of deglaciation. If increasing temperature and changing solar insolation were the sole drivers of this initial deglaciation, then temperature would need to have risen by slightly more than 1 degrees C/ky through this interval to account for the observed rate of ice recession.

The molten salt systems discussed herein use alloys, such as Hastelloy N and 242, that show good corrosion resistance in molten salt at nominal operating temperatures up to 700 [degrees]C. These alloys were diffusion welded, and the corresponding information is presented. Test specimens were prepared for exposing diffusion welds to molten salt environments. Hastelloy N and 242 were found to be weldable by diffusion welding, with ultimate tensile strengths about 90% of base metal values. Both diffusion welds and sheet material in Hastelloy N were corrosion tested in 58 mol% KF and 42 mol% ZrF sub(4) at 650, 700, and 850 [degrees]C for 200, 500, and 1000 h. Corrosion rates were similar between welded and non welded materials, typically <100 mu m per year after 1000 h of corrosion tests. No catastrophic corrosion was observed in the diffusion welded regions. For materials of construction, nickel-based alloys and alloys with dense nickel coatings are effectively inert to corrosion in fluorides, but not so in chlorides. Hence, additional testing of selected alloys for resistance to intergranular corrosion is needed, as is a determination of corrosion rate as a function of the type of salt impurity and alloy composition, with respect to chromium and carbon, to better define the best conditions for corrosion resistance. Also presented is the division of the nuclear reactor and high-temperature components per American Society of Mechanical Engineers (ASME) standards, along with design requirements for a subcritical Rankine power cycle heat exchanger that has to overcome pressure difference of about 17 MPa.

Therefore, spectral induced polarization (SIP) measurements can be used to monitor changes in bacterial biomass and growth stage. Our goal was to gain a better understanding of the SIP response of bacteria present in a porous material. Bacterial cell surfaces possess an electric double layer and therefore become polarized in an electric field. We performed SIP measurements over the frequency range of 0.1-1 kHz on cell suspensions alone and cell suspensions mixed with sand at four pore water conductivities. We used Zymomonas mobilis at four different cell densities (including the background). The quadrature conductivity spectra exhibited two peaks, one around 0.05-0.10 Hz and the other around 1-10 Hz. Because SIP measurements on bacterial suspensions are typically made at frequencies greater than 1 Hz, these peaks have not been previously reported. In the bacterial suspensions in growth medium, the quadrature conductivity at peak I was linearly proportional to the density of the bacteria. For the case of the suspensions mixed with sands, we observed that peak II presented a smaller increase in the quadrature conductivity with the cell density. A comparison of the experiments with and without sand grains illustrated the effect of the porous medium on the overall quadrature conductivity response (decrease in the amplitude and shift of the peaks to the lower frequencies). Our results indicate that for a given porous medium, time-lapse SIP has potential for monitoring changes in bacterial abundance within porous media.

To understand the influence of oxygen presence on high moisture biomass (50 %, wet basis), three airflow rates were tested on corn stover stored in laboratory reactors. Temperature, carbon dioxide production, dry matter loss, chemical composition, fungal abundance, pH, and organic acids were used to monitor the effects of airflow on storage conditions. The results of this work indicate that oxygen availability impacts both the duration of self-heating and the severity of dry matter loss. High airflow systems experienced the greatest initial rates of loss but a shortened microbially active period that limited total dry matter loss (19 %). Intermediate airflow had improved preservation in short-term storage compared to high airflow systems but accumulated the greatest dry matter loss over time (up to 27 %) as a result of an extended microbially active period. Low airflow systems displayed the best performance with the lowest rates of loss and total loss (10 %) in storage at 50 days. Total structural sugar levels of the stored material were preserved, although glucan enrichment and xylan loss were documented in the high and intermediate flow conditions. By understanding the role of oxygen availability on biomass storage performance, the requirements for high moisture storage solutions may begin to be experimentally defined.

PQ0002252094 AB - Benchmark models were developed to evaluate 11 critical core configurations of the HTRPROTEUS pebble bed experimental program. Various additional reactor physics measurements were carried out as part of this program; currently, only a total of 37 absorber rod worth measurements have been evaluated as acceptable benchmark experiments for cores 4, 9, and 10. Dominant uncertainties in the experimental k sub(e)fffor all core configurations come from uncertainties in the super(235)U enrichment of the fuel, impurities in the moderator pebbles, and the density and impurity content of the radial reflector. Calculations of k sub(eff) with MCNP5 and ENDF/B-VII.0 neutron nuclear data are greater than the benchmark values but are within 1% and also within the 3[sigma] uncertainty, except for core 4, which is the only randomly packed pebble configuration. Repeated calculations of k sub(eff) with MCNP6.1 and ENDF/B-VII.1 are lower than the benchmark values but are within 1% (~3[sigma]), except for cores 5 and 9, which calculate lower than the benchmark eigenvalues by <4[sigma]. The primary difference between the two nuclear data libraries is the adjustment of the absorption cross section of graphite. Simulations of the absorber rod worth measurements are within 3[sigma] of the benchmark experiment values. The complete benchmark evaluation details are available in the 2014 edition of the International Handbook of Evaluated Reactor Physics Benchmark Experiments JF - Nuclear Science and Engineering AU - Bess, John D AU - Montierth, Leland M AU - Koberl, Oliver AU - Snoj, Luka AD - Idaho National Laboratory, P.O.

Two Organisation for Economic Cooperation and Development (OECD)/Nuclear Energy Agency (NEA) activities, the International Criticality Safety Benchmark Evaluation Project (ICSBEP), initiated in 1992, and the International Reactor Physics Experiment Evaluation Project (IRPhEP), initiated in 2003, have been identifying existing integral experiment data, evaluating those data, and providing integral benchmark specifications for methods and data validation for nearly two decades. Data provided by those two projects will be of use to the international reactor physics, criticality safety, and nuclear data communities for future decades. An overview of the IRPhEP and a brief update of the ICSBEP are provided in this paper.

Additional measurements of the subcritical configuration of the fully loaded core, core excess reactivity, shutdown margins, six isothermal temperature coefficients, and axial reaction-rate distributions were also evaluated as acceptable benchmark experiments. Insufficient information is publicly available to develop finely detailed models of the HTTR as much of the design information is still proprietary. The uncertainties in the benchmark models are judged to be of sufficient magnitude to encompass any biases and bias uncertainties incurred through the simplification process used to develop the benchmark models. However, use of the benchmark critical configurations of the HTTR for nuclear data adjustment is not recommended as the impact of these biases has not been addressed with rigorous detail. The impact of any simplification biases, if any, is not expected to significantly impact evaluation of the other reactor physics measurement calculations. Dominant uncertainties in the experimental k sub(e)fffor all core configurations come from uncertainties in the impurity content of the various graphite blocks that compose the HTTR. Monte Carlo calculations of k sub(eff) between ~0.9% and ~2.7% greater than the benchmark values. Reevaluation of the HTTR models as additional information becomes available could improve the quality of this benchmark and possibly reduce the computational biases. High-quality characterization of graphite impurities would significantly improve the quality of the HTTR benchmark assessment. Simulations of the other reactor physics measurements are in good agreement with the benchmark experiment values.

Where found, they provide insight into how the coupling of the ocean-atmosphere system is manifested in biotic and environmental records and how the biosphere responds to climate change. In 2010-2011, construction at Ziegler Reservoir near Snowmass Village, Colorado (USA) revealed a nearly continuous, lacustrine/wetland sedimentary sequence that preserved evidence of past plant communities between approximately 140 and 55 ka, including all of MIS 5. At an elevation of 2705 m, the Ziegler Reservoir fossil site also contained thousands of well-preserved bones of late Pleistocene megafauna, including mastodons, mammoths, ground sloths, horses, camels, deer, bison, black bear, coyotes, and bighorn sheep. In addition, the site contained more than 26,000 bones from at least 30 species of small animals including salamanders, otters, muskrats, minks, rabbits, beavers, frogs, lizards, snakes, fish, and birds. The combination of macro- and micro-vertebrates, invertebrates, terrestrial and aquatic plant macrofossils, a detailed pollen record, and a robust, directly dated stratigraphic framework shows that high-elevation ecosystems in the Rocky Mountains of Colorado are climatically sensitive and varied dramatically throughout MIS 5.

This study employs a 2-D coupled mass/energy balance and flow model to assess the magnitudes of temperature and precipitation change that could have sustained the glacier in mass-balance equilibrium at its maximum extent during the Bull Lake glaciation. Variable substrate effects on glacier flow and ice thickness make the modeling somewhat more complex than in geologically simpler settings. Model results indicate that a temperature depression of about 6.7 degrees C compared with the present (1971-2000 AD) would have been necessary to sustain the Snowmass Creek glacier in mass-balance equilibrium during the Bull Lake glaciation, assuming no change in precipitation amount or seasonality. A 50% increase or decrease from modern precipitation would have been coupled with 5.2 degrees C and 9.1 degrees C Bull Lake temperature depressions respectively. Uncertainty in these modeled temperature depressions is about 1 degrees C. Abstract Copyright (2014) Elsevier, B.V.

This paper summarizes the recent TEM microstructural characterization of an irradiated U-7Mo/Al-5Si dispersion fuel plate (R3R050) in the Advanced Test Reactor (ATR) at Idaho National Laboratory (INL) to 5.2 x 10 super(21) fissions/cm super(3). While a large fraction of the fuel grains is decorated with large bubbles, there is no evidence showing interlinking of these bubbles at the specified fission density. The attachment of solid fission product precipitates to the bubbles is likely the result of fission product diffusion into these bubbles. The process of fission gas bubble superlattice collapse appears through bubble coalescence. The results are compared with the previous TEM work on the dispersion fuels irradiated to lower fission density from the same fuel plate.

The DEM model clearly predicts realistic early-life crack patterns including both radial and circumferential cracks. Simulation results clearly demonstrate the formation of radial cracks during the initial power rise and formation of circumferential cracks as the power is ramped down. In these simulations, additional early-life power cycles do not lead to the formation of new thermal cracks. They do, however clearly indicate changes in the apertures of thermal cracks during later power cycles due to thermal expansion and shrinkage. The number of radial cracks increases with increasing power, which is consistent with the experimental observations.

This experiment was irradiated in the Advanced Test Reactor (ATR) at Idaho National Laboratory (INL) and is currently undergoing post-irradiation examination (PIE) at INL and Oak Ridge National Laboratory. Gamma spectrometry was used to non-destructively evaluate the burnup of all 72 of the TRISO fuel compacts that comprised the AGR-1 experiment. Two methods for evaluating burnup by gamma spectrometry were developed, one based on the Cs-137 activity and the other based on the ratio of Cs-134 and Cs-137 activities. Burnup values determined from both methods compared well with the values predicted from simulations. The results confirm the accuracy of the nondestructive burnup evaluation from gamma spectrometry for TRISO fuel compacts across a burnup range of approximately 10-20% FIMA and also validate the approach used in the physics simulation of the AGR-1 experiment.

The ash content of biomass is one such specification, influencing pretreatment and disposal costs for the conversion facility and the overall value of a delivered lot of biomass. The biomass harvest process represents a primary pathway for accumulation of soil-derived ash within baled material. In this work, the influence of five collection techniques on the total ash content and variability of ash content within baled corn stover in southwest Kansas is discussed. The equipment tested included a mower for cutting the corn stover stubble, a basket rake, wheel rake, or shred flail to gather the stover, and a mixed or uniform in-feed baler for final collection. The results showed mean ash content to range from 11.5 to 28.2 % depending on operational choice. Resulting impacts on feedstock costs for a biochemical conversion process range from $5.38 to $22.30 Mg super(-1) based on the loss of convertible dry matter and ash disposal costs. Collection techniques that minimized soil contact (shred flail or nonmowed stubble) were shown to prevent excessive ash contamination, whereas more aggressive techniques (mowing and use of a wheel rake) caused greater soil disturbance and entrainment within the final baled material. Material sampling and testing were shown to become more difficult as within-bale ash variability increased, creating uncertainty around feedstock quality and the associated costs of ash mitigation.

Diffusion coefficients of UCl sub(4) and UCl sub(3) were calculated to be (6.72 + or - 0.360) x 10 super(-6) cm super(2)/s and (1.04 + or - 0.17) x 10 super(-5) cm super(2)/s, respectively. Apparent standard reduction potentials were determined to be (-0.381 + or - 0.013) V and (-1.502 + or - 0.076) V vs. 5 mol% Ag/AgCl or (-1.448 + or - 0.013) V and (-2.568 + or - 0.076) V vs. Cl sub(2)/Cl super(-) for the U(IV)/U(III) and U(III)/U redox couples, respectively. In comparing this data with supercooled thermodynamic data to determine activity coefficients, the thermodynamic database used was important with resulting activity coefficients ranging from 2.34 x 10 super(-3) to 1.08 x 10 super(-2) for UCl sub(4) and 4.94 x 10 super(-5) to 4.50 x 10 super(-4) for UCl sub(3). Of anodic stripping voltammetry and cyclic voltammetry anodic or cathodic peaks, the CV cathodic peak height divided by square root of scan rate was shown to be the most reliable method of determining UCl sub(3) concentration in the molten salt.

The anisotropic fracture behavior due to the different grain boundary characters was investigated with the [left angle bracket]100[right angle bracket] symmetrical tilt [Sigma]5 and the [left angle bracket]110[right angle bracket] symmetrical tilt [Sigma]3 ({111} twin) grain boundaries. Nine interatomic potentials, seven rigid-ion plus two core-shell ones, were utilized to elucidate possible potential dependence. Initiating from a notch, crack propagation along grain boundaries was observed for most potentials. The [Sigma]3 boundary was found to be more prone to fracture than the [Sigma]5 one, indicated by a lower energy release rate associated with the former. However, some potential dependence was identified on the existence of transient plastic deformation at crack tips, and the results were discussed regarding the relevant material properties including the excess energies of metastable phases and the critical energy release rate for intergranular fracture. In general, local plasticity at crack tips was observed in fracture simulations with potentials that predict low excess energies for metastable phases and high critical energy release rates for intergranular fracture.

However there has been limited effort to develop physics-based models incorporating this mechanism for the analysis of FGR. In this work, a computational study is carried out to investigate GB separation in UO sub(2) fuel under the effect of gas bubble pressure and hydrostatic stress. A non-dimensional stress intensity factor formula is obtained through 2D axisymmetric analyses considering lenticular bubbles and Mode-I crack growth. The obtained functional form can be used in higher length-scale models to estimate the contribution of GB separation to FGR.

In this comparison, the governing equations for mass, momentum and energy conservation are evaluated. It will be shown that the governing equations do not vary substantially between the codes considered. Most of them utilize a lumped approach with only two fields to represent two phase flow. In the second part of this article, the closure relations, experimental verification and validation are discussed.

In this second part of the article series, the system code closure relationships (used to model thermal and mechanical non-equilibrium and the coupling of the phases) for the governing equations are discussed and evaluated. These include several thermal and hydraulic models, such as heat transfer coefficients for various flow regimes, two phase pressure correlations, two phase friction correlations, drag coefficients and interfacial models between the fields. These models are often developed from experimental data. The experiment conditions should be understood to evaluate the efficacy of the closure models. This second part completes the series on the comparison and evaluation of the selected reactor system codes by discussing the closure relations, validation and limitations.

The dimensional changes of the fuel particle layers and kernel were calculated, including the formation of an internal gap. The survivability of the UN TRISO particle was estimated depending on the strain behavior of the constituent materials at high fast fluence and burn-up. For nominal cases, internal gas pressure and representative thermal profiles across the kernel and layers were determined along with stress levels in the inner and outer pyrolytic carbon (IPyC/OPyC) and silicon carbide (SiC) layers. These parameters were then used to evaluate fuel particle failure probabilities. Results of the study show that the survivability of UN TRISO fuel under LWR irradiation conditions might only be guaranteed if the kernel and PyC swelling rates are limited at high fast fluence and burn-up. These material properties have large uncertainties at the irradiation levels expected to be reached by UN TRISO fuel in LWRs. Therefore, a large experimental effort would be needed to establish material properties, including kernel and PyC swelling rates, under these conditions before definitive conclusions can be drawn on the behavior of UN TRISO fuel in LWRs.

A nuclear reactor intended for use in space must remain subcriticai before and during launch, and must remain subcriticai in launch abort scenarios where the reactor falls back to Earth and becomes submerged in terrestrial materials (including seawater, wet sand, or dry sand). Submersion increases reflection of neutrons and also thermalizes the neutron spectrum, which typically increases the reactivity of the core. This effect is typically very significant for compact, fast-spectrum reactors. This paper provides a submersion criticality safety analysis for a representative tungsten/uranium oxide fueled reactor with a range of fuel compositions. Each submersion case considers both the rhenium content in the matrix alloy and the uranium oxide volume fraction in the cermet. The inclusion of rhenium significantly improves the submersion criticality safety of the reactor. While increased uranium oxide content increases the reactivity of the core, it does not significantly affect the submersion behavior of the reactor. There is no significant difference in submersion behavior between reactors with rhenium distributed within the cermet matrix and reactors with a rhenium clad in the coolant channels. The combination of the flooding of the coolant channels in submersion scenarios and the presence of a significant amount of spectral shift absorbers (i.e. high rhenium concentration) further decreases reactivity for short reactor cores compared to longer cores.

The process heat industry/facilities will be located outside the nuclear island due to safety measures. This thermal energy from the reactor must be transported a fair distance. In this study, the analytical analysis was conducted to identify the maximum distance that thermal energy could be transported using various coolants such as molten-salts, helium, and water by varying the pipe diameter and mass flow rate. The cost required to transport each coolant was also analyzed. The coolants analyzed are molten salts (such as: KClMgCl sub(2), LiF-NaF-KF (FLiNaK) and KF-ZrF sub(4)), helium, and water. Fluoride salts are superior because of better heat transport characteristics, but chloride salts are most economical for higher temperature transportation purposes. For lower temperature, the water is a possible alternative when compared with helium because low-pressure helium requires extremely high pumping power, which makes the process very inefficient and economically not viable for both low and high-temperature application.

Our objective was to demonstrate a landscape planning process that can ensure adequate supplies of corn (Zea mays L.) stover feedstock while protecting and improving soil quality. The Landscape Environmental Assessment Framework (LEAF) was used to develop land use strategies that were then scaled up for five U.S. Corn Belt states (Nebraska, Iowa, Illinois, Indiana, and Minnesota) to illustrate the impact that could be achieved. Our results show an annual sustainable stover supply of 194 million Mg without exceeding soil erosion T values or depleting soil organic carbon [i.e., soil conditioning index (SCI)>0] when no-till, winter cover crop, and vegetative barriers were incorporated into the landscape. A second, more rigorous conservation target was set to enhance soil quality while sustainably harvesting stover. By requiring erosion to be 0, the annual sustainable quantity of harvestable stover dropped to148 million Mg. Examining removal rates by state and soil resource showed that soil capability class and slope generally determined the effectiveness of the three conservation practices and the resulting sustainable harvest rate. This emphasizes that sustainable biomass harvest must be based on subfield management decisions to ensure soil resources are conserved or enhanced, while providing sufficient biomass feedstock to support the economic growth of bioenergy enterprises.

However, the accuracy of paleoclimate reconstructions from glacial geology is limited by the challenge of representing mountain meteorology in numerical models. Precipitation is usually treated in a simple manner and yet represents difficult-to-characterize variables such as amount, distribution, and phase. Furthermore, precipitation distributions during a glacial probably differed from present-day interglacial patterns. We applied two models to investigate glacier sensitivity to temperature and precipitation in the eastern Southern Alps of New Zealand. A 2-D model was used to quantify variations in the length of the reconstructed glaciers resulting from plausible precipitation distributions compared to variations in length resulting from change in mean annual air temperature and precipitation amount. A 1-D model was used to quantify variations in length resulting from interannual climate variability. Assuming that present-day interglacial values represent precipitation distributions during the last glacial, a range of plausible present-day precipitation distributions resulted in uncertainty in the Last Glacial Maximum length of the Pukaki Glacier of 17.1 km (24%) and the Rakaia Glacier of 9.3 km (25%), corresponding to a 0.5 degrees C difference in temperature. Smaller changes in glacier length resulted from a 50% decrease in precipitation amount from present-day values (-14% and -18%) and from a 50% increase in precipitation amount (5% and 9%). Our results demonstrate that precipitation distribution can produce considerable variation in simulated glacier extents and that reconstructions of paleoglaciers should include this uncertainty.

Irradiated AGR-1 fuel compacts have been cross-sectioned and analyzed with optical microscopy to characterize kernel, buffer, and coating behavior. Six compacts have been examined, spanning a range of irradiation conditions (burnup, fast fluence, and irradiation temperature) and including all fourTRlSO coating variations irradiated in the AGR-1 experiment. The cylindrical specimens were sectioned both transversely and longitudinally, then polished to expose from 36 to 79 individual particles near midplane on each mount. The analysis focused primarily on kernel swelling and porosity, buffer densification and fracturing, buffer-IPyC debonding, and fractures in the IPyC and SiC layers. Characteristic morphologies have been identified, 981 particles have been classified, and spatial distributions of particle types have been mapped. No significant spatial patterns were discovered in these cross sections. However, some trends were found between morphological types and certain behavioral aspects. Buffer fractures were found in 23% of the particles, and these fractures often resulted in unconstrained kernel protrusion into the open cavities. Fractured buffers and buffers that stayed bonded to IPyC layers appear related to larger pore size in kernels. Buffer-IPyC interface integrity evidently factored into initiation of rare IPyC fractures. Fractures through part of the SiC layer were found in only four classified particles, all in conjunction with IPyC-SiC debonding. Compiled results suggest that the deliberate coating fabrication variations influenced the frequencies of IPyC fractures and IPyC-SiC debonds.

These irradiations and fuel development are being accomplished to support development of the next generation reactors in the United States, and will be irradiated over the next several years to demonstrate and qualify new TRISO coated particle fuel for use in high temperature gas reactors. The goals of the irradiation experiments are to provide irradiation performance data to support fuel process development, to qualify fuel for normal operating conditions, to support development and validation of fuel performance and fission product transport models and codes, and to provide irradiated fuel and materials for post irradiation examination (PIE) and safety testing.

The graphite experiments will be irradiated over the next six to eight years to support development of a graphite irradiation performance data base on the new nuclear grade graphites now available for use in high temperature gas reactors. The goals of the irradiation experiments are to obtain irradiation performance data, including irradiation creep, at different temperatures and loading conditions to support design of the next generation nuclear plant (NGNP) very high temperature gas reactor, as well as other future gas reactors. The experiments will each consist of a single capsule that will contain six peripheral stacks of graphite specimens, with half of the graphite specimens in each stack under a compressive load, while the other half of the specimens will not be subjected to a compressive load during irradiation. The six peripheral stacks will have three different compressive loads applied to the top half of three diametrically opposite pairs of specimen stacks, while a seventh stack will not have a compressive load. The specimens will be irradiated in an inert sweep gas atmosphere with on-line temperature and compressive load monitoring and control. There will also be sampling the sweep gas effluent to determine if any oxidation or off-gassing of the specimens occurs during irradiation of the experiment.

During this multi-year experiment, release-to-birth rate ratios were computed at the end of each operating interval to provide information about fuel performance. Fission products released during irradiation were tracked daily by the Fission Product Monitoring System using 8-h measurements. Birth rate calculated by MCNP with ORIGEN for as-run conditions were computed at the end of each irradiation interval. Each time step in MCNP provided neutron flux, reaction rates and AGR-1 compact composition, which were used to determine birth rate using ORIGEN. The initial birth-rate data, consisting of four values for each irradiation interval at the beginning, end, and two intermediate times, were interpolated to obtain values for each 8-h activity. The problem with this method is that any daily changes in heat rates or perturbations, such as shim control movement or core/lobe power fluctuations, would not be reflected in the interpolated data and a true picture of the system would not be presented. At the conclusion of the AGR-1 experiment, great efforts were put forth to compute daily birthrates, which were reprocessed with the 8-h release activity. The results of this study are presented in this paper.

The AGR tests employ fuel compacts placed in a graphite cylinder shrouded by a steel capsule and instrumented with thermocouples (TC) embedded in graphite blocks enabling temperature control. While not possible to obtain by direct measurements in the tests, crucial fuel conditions are calculated using core physics and thermal modeling codes. This paper is focused on AGR test fuel temperature predicted by the ABAQUS code's finite element-based thermal models. This suggests a more physics-based modification of the thermal model that leads to a better fit with experimental data, thus reducing model uncertainty and increasing confidence in the calculated fuel temperatures of the AGR-1 test.

In this paper the possible mechanisms postulated in previous experimental studies, both in-reactor and out-of reactor research environment studies are critically reviewed and of particular interest are relevance to very high temperature gas reactor operating and accident conditions. Among the factors thought to influence Ag transport are grain boundary stoichiometry. SIC grain size and shape, the presence of free silicon, nano-cracks, thermal decomposition, palladium attack, transmutation products, layer thinning and coated particle shape. Additionally new insight to nature and location of fission products has been gained via recent post irradiation electron microscopy examination of TRISO coated particles from the DOE's fuel development program. The combined effect of critical review and new analyses indicates a direction for investigating possible the Ag transport mechanism including the confidence level with which these mechanisms may be experimentally verified.

In this paper a brief summary of results from characterization of microstructures in the coating layers of selected irradiated fuel particles with burnup of 11.3% and 19.3% FIMA will be given. The main objectives of the characterization were to study irradiation effects, fuel kernel porosity, layer debonding, layer degradation or corrosion, fission-product precipitation, grain sizes, and transport of fission products from the kernels across the TRISO layers. Characterization techniques such as scanning electron microscopy, transmission electron microscopy, energy dispersive spectroscopy, and wavelength dispersive spectroscopy were used. A new approach to microscopic quantification of fission-product precipitates is also briefly demonstrated. Microstructural characterization focused on fission-product precipitates in the SiC-IPyC interface, the SIC layer and the fuel-buffer interlayer. The results provide significant new insights into mechanisms of fission-product transport. Although Pd-rich precipitates were identified at the SiC-IPyC interlayer. no significant SiC-layer thinning was observed for the particles investigated. Characterization of these precipitates highlighted the difficulty of measuring low concentrations of Ag in precipitates with significantly higher concentrations of Pd and U. Different approaches to resolving this problem are discussed. An initial hypothesis is provided to explain fission-product precipitate compositions and locations. No SiC phase transformations were observed and no debonding of the SiC-IPyC interlayer as a result of irradiation was observed for the samples investigated. Lessons learned from the post-irradiation examination are described and future actions are recommended.

Historically characterization was limited by instrumentation available. Great strides have been made in new characterization techniques, yet there application to irradiated fuels has been delayed due to the difficulty of working with the samples. This paper outlines the first results from the application of a dual-column focused ion beam along with energy dispersive spectroscopy and electron backscatter diffraction detectors to analyze the 3D structure of high burn-up MOX fuel. The applicability and advantages of the advanced techniques to irradiated fuel are also discussed.

Although these results are encouraging, there exists much uncertainty surrounding the influence of fracture-controlled reservoir heterogeneity on commercial-scale CO (sub 2) injections in basalt formations. This work investigates the physical response of a low-volume basalt reservoir to commercial-scale CO (sub 2) injections using a Monte Carlo numerical modeling experiment such that model variability is solely a function of spatially distributed reservoir heterogeneity. Fifty equally probable reservoirs are simulated using properties inferred from the deep eastern Snake River Plain aquifer in southeast Idaho, and CO (sub 2) injections are modeled within each reservoir for 20 yr at a constant mass rate of 21.6 kg s (super -1) . Results from this work suggest that (1) formation injectivity is generally favorable, although injection pressures in excess of the fracture gradient were observed in 4% of the simulations; (2) for an extensional stress regime (as exists within the eastern Snake River Plain), shear failure is theoretically possible for optimally oriented fractures if S (sub h) < or = 0.70S (sub V) ; and (3) low-volume basalt reservoirs exhibit sufficient CO (sub 2) confinement potential over a 20 yr injection program to accommodate mineral trapping rates suggested in the literature.

Samples were collected under open borehole conditions and after installing a multilevel groundwater monitoring system completed with 11 discrete monitoring zones within dense and fractured basalt and sediment layers in the eastern Snake River aquifer. The study was done in cooperation with the U.S. Department of Energy to test whether ambient fracture flow conditions were sufficient to remove the effects of injected drill water prior to sample collection. Results from thief samples indicated that the tracer was present in minor concentrations 28 days after coring, but was not present 6 months after coring or 7 days after reaming the borehole. Results from sampling the multilevel monitoring system indicated that small concentrations of the tracer remained in 5 of 10 zones during some period after installation. All concentrations were several orders of magnitude lower than the initial concentrations in the drill water. The ports that had remnant concentrations of the tracer were either located near sediment layers or were located in dense basalt, which suggests limited groundwater flow near these ports. The ports completed in well-fractured and vesicular basalt had no detectable concentrations. Abstract Copyright Published 2013.

During a refueling outage, the Outage Control Center (OCC) is the temporary command center for outage managers and provides several critical functions for successful execution of the outage schedule. Essentially, the OCC functions to facilitate information inflow, assist outage management with processing information, and facilitate the dissemination of information to stakeholders. Currently, outage management activities primarily rely on telephone communications, face-to-face reports, and periodic briefings in the OCC. It is a difficult task to maintain current information related to outage progress and any discovered conditions.

Plant designs often include an intermediate heat transfer loop (IHTL) with heat exchangers at either end to deliver thermal energy to the application while providing isolation of the primary reactor coolant system. In order to address technical feasibility concerns and challenges associated with the IHTL, a new high-temperature multi-fluid, multi-loop test facility called the Advanced Reactor Technology Integral System Test (ARTIST) facility is under development at the Idaho National Laboratory (INL). The facility will include three flow loops: high-temperature helium, molten salt, and steam/water. The three loops will be thermally coupled through an intermediate heat exchanger (IHX) and a secondary heat exchanger (SHX).

To reduce the potential long-term hazard of radioactive wastes, transmutation of MAs is considered to be an important option for the future nuclear fuel cycle. Mixed oxide containing, MAs (MA-MOX) are a promising candidates fuel for the transmutation in fast reactor.[11, 2] The local and electronic stmctures around the Am atom in oxide fuels would yield an immense amount of information because the valence state of Am strongly affects the oxygen potentials and thermal properties of MA-MOX fuels.

This ability is in particular relevant in the nuclear industry where accidents may have major impacts from an economic, health and societal point of view. As an example, the Fukushima Dai-ichi nuclear power plant accident highlighted the importance of the ability of plant operators and plant staff to react quickly and effectively in accident conditions. This particular event showed the importance of being able to: [bullet] Determine/estimate the actual status of the plant (i.e., diagnosis) when the monitoring system is corrupted or partially unavailable, and, [bullet] Forecast its future evolution (i.e., prognosis).

Mihalczo (team leader), J. J. Lynn, and J. R. Taylor performed experiments at the Oak Ridge Critical Experiments Facility (ORCEF) with highly enriched uranium (HEU) metal (called Oak Ridge Alloy or ORALLOY) to recreate GODIVA I results with greater accuracy than those performed at Los Alamos National Laboratory in the 1950s. The purpose of the Oak Ridge ORALLOY Sphere (ORSphere) experiments was to estimate the unreflected and unmoderated critical mass of an idealized sphere of uranium metal corrected to a density, purity, and enrichment such that it could be compared with the GODIVA I experiments [1]. Part of the experimental series was the measurement of various kinetic parameters including the prompt neutron decay constant, alpha , and the delayed neutron fraction, beta sub(eff). Although not presented by the experimenter the mean neutron generation time, [Lambda], can also be derived using the benchmark alpha and beta sub(eff) values. All three of these kinetic parameters measurements have been evaluated and found to be acceptable and are discussed in full detail in the International Handbook of Evaluated Reactor Physics Benchmark Experiments [2].

Four different waste glass formulations were evaluated - two HLW compositions and two LAW compositions with different thermophysical properties. The thermal properties and heat generation rate used in the analysis are conservative and were chosen to match those used in the HVAC design by the WTP contractor. The two HLW formulations exhibit similar temperature distributions within the glass after 40 hrs. of cooling, as do the two LAW formulations. At initial times after pouring, thermal radiation is the dominant mode of heat transfer. At longer times, the contribution from thermal radiation to heat loss from the container/canister becomes nearly comparable to that from free convection. Thermal gradients within the glass canister are less than several degrees. Future work includes simulating the heat transfer to the surroundings resulting from discrete pours of molten glass into the containers/canisters. This will provide a more realistic estimate of the heat rejected from the containers/canisters as a function of time during cooling.

It is well known that the ICE method introduces first-order time integration errors. Mousseau gave excellent analyses on the operator-splitting time integration errors in several of his works [3, 4, 5]. For spatial discretization, first-order staggered grid upwind method was generally used in the existing codes, which is robust and 'regulates' the ill-posedness of the commonly used two fluid six equations two-phase flow model. However, it introduces numerical diffusion, which is not desirable for certain scenarios such as long lasting transients.

Computational fluid dynamics (CFD) codes solve only a piece of the core. There is a need for a whole core dynamics system code with local resolution to investigate and understand flow behavior with all the relevant physics and thermomechanics. The matched index of refraction (MIR) flow facility at Idaho National Laboratory (INL) has a unique capability to contribute to the development of validated CFD codes through the use of state-of-the-art optical measurement techniques, such as Laser Doppler Velocimetry (LDV) and Particle Image Velocimetry (PIV). PIV is a non-intrusive velocity measurement technique that tracks flow by imaging the movement of small tracer particles within a fluid.

The primary short-comings of lithium-ion batteries are the flammability of the liquid electrolyte and sensitivity to high voltage and elevated temperatures. We have synthesized a series of non-flammable fluorinated phosphazene liquids and blended them with conventional carbonate solvents. While the use of these phosphazenes as standalone electrolytes is highly desirable, they simply do not satisfy all of the many requirements that must be met such as high LiPF sub(6) solubility and low viscosity, thus we have used them as additives and co-solvents in blends with typical carbonates. The physical and electro-chemical properties of the electrolyte blends were characterized, and then the blends were used to build 2032-type coin cells. We have evaluated the performance of the electrolytes by determining the physical properties, thermal stability, electrochemical window, cell cycling data, and the ability to form solid electrolyte interphase (SEI) films. This paper presents our most recent results on a new series of fluorinated cyclic phosphazene trimers, the FM series, which has exhibited numerous beneficial effects on battery performance, lifetimes, and safety aspects.

The detailed surface mass balance scheme also allows us to determine the likely locations of initial glacier growth and subsequent coalescence (e.g. the Beartooth plateau, Absaroka mountains). Second, we explore explanations for spatial asynchronies in the Yellowstone Ice Cap LGM moraine ages. The maximum terminal moraine ages from the western portion of the ice cap are one to four thousand years younger than ages on the east side of the ice cap (Licciardi and Pierce, 2008). As a potential explanation for this discrepency, we assess the importance of orographic precipitation in promoting the westward growth of the ice cap through time (e.g., Pierce, 1979) and the potential for a thickening ice cap to reduce leeside accumulation leading to the contraction of eastward-flowing outlet glaciers. For this exploration, we use an efficient semi-implicit 2-D ice-flow model with a surface mass balance scheme that allows inclusion of a simple algorithm for orographically-forced precipitation (e.g., Roe, 2005). Finally, we couple the semi-implicit 2-D ice-flow model to a fully implicit solution for flexural isostatic response to the evolving ice load, and test the sensitivity of the ice cap to a generous range of plausible solid Earth rheologies. This provides initial estimates of the effect of flexural depression on ice dynamics, potential locations of proglacial lakes, and the location and magnitude of the forebulge. This modeling effort was inspired by the instruction of Bill Locke at Montana State University and the work of Ken Pierce and Joe Licciardi, whose modeling and cosmogenic radionuclide dating efforts inform and constrain our research.

In nuclear fuels which are primarily made of UO sub(2) currently, GB motion has significant impact on fuel performance by affecting the thermal conductivity, fission gas release and defect accumulation induced by radiation damage. Obtaining GB mobility is critical for predictive modeling of fuel performance in reactors.

Uranium-zirconium (U-Zr) alloys represent one of the types of fuels that are under consideration for use within these reactors. Metallic fuels have been investigated for over five decades in numerous reactors [1, 2], However, these previous investigations tended to focus on fuel performance phenomena, such as the maximum burn-up. This study is meant to focus on the early stages of fuel performance through the understanding of microstructural evolution of nuclear fuel subjected to low neutron fluences. Understanding the fuel behavior at low fluences is key to parameterizing and validating the microstructural nuclear fuel simulations.

Conceptual design requires an outlet temperature of greater than 850[degrees]C to provide for the efficient generation of hydrogen, with a desired maximum outlet temperature of 950[degrees]C. A critical component in the VHTR system for extracting thermal energy at these temperatures is the Intermediate Heat Exchanger (IHX), which will be required to operate at reactor outlet temperatures of up to 950[degrees]C. The combination of very high temperature operation and long duration of service dictates the need for structural materials with good thermal stability as well as high temperature creep and oxidation resistance. Based on these material requirements, the nickel base alloy UNS N06617, Alloy 617, is the leading IHX candidate alloy [1].

Such information, while being coupled with continuum scale modeling methods, is invaluable to produce more accurate models for the structural evolution in fuels and materials in nuclear reactors. However, such coupling is challenging, as it requires simulations to pass information back and forth while using different time and spatial scales with different methods. In addition, PFC models capable of reproducing realistic material properties are currently highly desired in the community but yet to be realized.

These models are correlated to temperature and bumup, where the bumup is used to characterize the history of the fuel. However, bumup is an imprecise measure of the fuel history, as it is not unique; fuels at the same bumup can have different microstructures, and therefore different properties, depending on irradiation conditions.

The principle that guides their design concepts is to passively maintain core temperatures below fission product release thresholds under all accident scenarios. This level of fuel performance and fission product retention reduces the radioactive source term by many orders of magnitude and allows potential elimination of the need for evacuation and sheltering beyond a small exclusion area. This level, however, is predicated on exceptionally high quality fuel fabrication quality and performance under normal operation and accident conditions. Germany produced and demonstrated high-quality fuel for their pebble bed HTGRs in the 1980s, but no U.S. manufactured fuel had exhibited equivalent performance prior to the Advanced Gas Reactor (AGR) Fuel Development and Qualification Program. The design goal of the modular HTGRs is to allow elimination of an exclusion zone and an emergency planning zone outside the plant boundary fence, typically interpreted as being about 400 meters from the reactor. To achieve this, the reactor design concepts require a level of fuel integrity that is better than that claimed for all prior U.S.-manufactured tristructural isotropic (TRISO) fuel, by a few orders of magnitude and about a factor of three better than qualified for German TRISO fuel in the 1980's.

These events also highlight the importance of having confidence in instrumentation data for critical parameters when making accident management and mitigation decisions in an environment where operators are overwhelmed with superfluous and sometimes conflicting data. While progress in these areas has been made since TMI-2, the events at Fukushima indicate that there is still a need for further improvement.

The models use the Systems Analysis Programs for Hands-on Integrated Reliability Evaluations (SAPHIRE) code developed by the NRC and Idaho National Laboratory (INL). SAPHIRE, currently Version 8, is a powerful software with advanced features to perform separated or integrated Level 1, Level 2, internal events, external events, at-power, and low power shutdown PRA [1], One of its features is the availability of three different approaches to model the success branch of a top event in event tree: delete term, complement of system logic, and developed event. Improper choosing of the approach and modeling success branch might yield unexpected and incorrect results. This paper will discuss the two most often used success branch modeling approaches, delete term and developed event, and provide recommendations for using proper approaches in different models. A potential SAPHIRE code enhancement is also presented to efficiently address the impact brought by the developed event approach.

Several accident tolerant fuel concepts are currently being evaluated by industry lead teams in collaboration with national laboratories and universities. This work is part of one such collaboration. The primary uranium compound used in nuclear fuel worldwide is uranium dioxide (UO sub(2)) however alternative uranium compounds, such as uranium silicides, exists whose properties make them a potential alternative to UO sub(2) in nuclear fuel. In this work, samples of high density (>94% theoretical density) uranium silicide (U sub(3)Si sub(2)) have been fabricated by powder metallurgy techniques. The developed fabrication techniques will be used to create samples for irradiation testing in the Idaho National Laboratory (INL) Advanced Test Reactor (ATR). Post irradiation examination of these samples will provide important information on the performance of U sub(3)Si sub(2) under typical LWR conditions.

The development of these fuels requires that a suitable high uranium density fuel phase be identified, developed, and qualified for service. Conversion of reactors that currently use HEU (highenriched uranium) must occur without significant impact to reactor mission performance, safety, or operating cost. Deployment of these fuels results in a significant decrease in HEU commerce. Professor Olander was invited to serve as a technical reviewer in 2006 to help guide this challenging program. The fuels developed by this program with Professor Olander's participation provide a interesting technical narrative.

These methods have involved expert knowledge with regards to reactor plant transients and thermal-hydraulic codes to identify are of highest importance. A PIRT provides a rigorous method for quantifying the phenomena that can have the greatest impact. The transients that are evaluated and the timing of those events are typically developed in collaboration with the Probabilistic Risk Analysis. Though quite effective in evaluating risk, traditional PRA methods lack the capability to evaluate complex dynamic systems where end states may vary as a function of transition time from physical state to physical state.

This program was refocused from enhanced performance to enhanced accident tolerance following the events at the Japanese Fukushima Daiichi nuclear power plant in 2011. Accident tolerant fuels have been specifically described as fuels that, in comparison with the standard uranium oxide (UO sub(2))-Zircaloy fuel design, can tolerate loss of active cooling in the reactor core for a considerably longer time period (depending on the LWR system and accident scenario) while maintaining or improving the fuel performance during normal operations, operational transients, as well as design-basis and beyond design-basis events. The program maintains an ambitious goal to insert a lead test assembly (LTA) of the new design into a commercial power reactor by 2022[i].

There are several issues or concerns that warrant more detailed study, such as precipitation along the cladding-to-cladding bond line, chemical banding, uncovered fuel-zone edge, and the interaction layer between the U-Mo fuel meat and zirconium. Future post-irradiation examination results will focus, among other things, on identifying in-reactor failure mechanisms and, eventually, directing further fresh fuel characterization efforts.

However, understanding the basic mechanism of transport is still lacking. This understanding is important because the TRISO coating is part of the high temperature gas-cooled reactor functional containment and critical for the safety strategy for licensing purposes. Our approach to identify fission products in irradiated AGR-1 TRISO fuel using scanning transmission electron microscopy (STEM), electron energy loss spectroscopy (EELS) and energy filtered TEM (EFTEM), has led to first-of-a-kind data at the nano-scale indicating the presence of silver at triple-points and grain boundaries of the SiC layer in the TRISO particle. The findings reported in this paper may support the postulations of recent research that Ag transport may be driven by grain boundary diffusion. Additionally, the usefulness of the advanced electron microscopic techniques for TRISO coated particle research is demonstrated in this paper.

Over more than 60 years these materials displayed a very good combination of properties such as low neutron absorption, creep behavior, stress-corrosion cracking resistance, reduced hydrogen uptake, corrosion, and/or oxidation, especially in the case of Zircaloy-4 [1-3]. However, over the last couple of years energetic efforts were undertaken to improve their oxidation resistance during off-normal temperature excursions, as well as to further improve upon the already achieved levels of mechanical behavior and reduced hydrogen uptake [1-3]. In order to facilitate the development of such novel materials, it is very important to achieve not only engineering control, but also scientific understanding of the underlying material degradation mechanisms, both in working conditions and in storage of spent nuclear fuel. This paper strives to contribute to these efforts by constructing the thermodynamic models of both alloys, constructing of the respective phase diagrams, and oxidation mechanisms. A special emphasis was placed upon the role of zirconium suboxides [4] in hydrogen uptake reduction and the atomic mechanisms of oxidation. To that end, computational thermodynamics calculations were conducted concurrently with first-principles atomistic modeling.

However, modeling the thermal conductivity of fuel is greatly complicated by the radially inhomogeneous nature of irradiated fuel in both composition and microstructure. In this work, radially and temperature-dependent models for effective thermal conductivity were developed utilizing optical micrographs of high burn-up mixed oxide fuel. The micrographs were employed to create finite element meshes with the OOF2 software. The meshes were then used to calculate the effective thermal conductivity of the microstructures using the BISON [1] fuel performance code. The new thermal conductivity models were used to calculate thermal profiles at end of life for the fuel pellets. These results were compared to thermal conductivity models from the literature, and comparison between the new finite element-based thermal conductivity model and the Duriez-Lucuta model was favorable.

Investigating influences of purging and sampling methodology on composition variability requires quantification of wellbore flow regimes and mixing. As a basis for this quantification, analytical models simulating Poiseuille flow were developed to calculate flow paths and travel times. Finite element modeling was used to incorporate influences of mixing. Parabolic velocity distributions within the screened interval accelerate with cumulative inflow approaching the pump intake while an annulus of inflowing formation water contracts uniformly to displace an axial cylinder of pre-pumping well water as pumping proceeds. Increased dispersive mixing forms a more diffuse formation water annulus and the contribution of formation water to pump effluent increases more rapidly. Models incorporating viscous flow and diffusion scale mixing show that initially pump effluent is predominantly pre-pumping well water and compositions vary most rapidly. After two screen volumes of pumping, 94% of pump effluent is inflowing formation water. Where the composition of formation water and pre-pumping well water are likely to be similar, pump effluent compositions will not vary significantly and may be collected during early purging or with passive sampling. However, where these compositions are expected to be considerably different or heterogeneous, compositions would be most variable during early pumping, that is, when samples are collected during low-flow sampling. Purging of two screen volumes would be required to stabilize the content and collect a sample consisting of 94% formation water.

Recently the need for quantitatively evaluating coupled Thermodynamic, Hydrologic, geoMechanical, and geoChemical (THMC) processes has grown, driven by new applications such as geologic sequestration of greenhouse gases and development of unconventional energy sources. Here we focus on Enhanced Geothermal Systems (EGS), which are man-made geothermal reservoirs created where hot rock exists but there is insufficient natural permeability and/or pore fluids to allow efficient energy extraction. In an EGS, carefully controlled subsurface fluid injection is performed to enhance the permeability of pre-existing fractures, which facilitates fluid circulation and heat transport. EGS technologies are relatively new, and pose significant simulation challenges. To become a trusted analytical tool for EGS, numerical simulation codes must be tested to demonstrate that they adequately represent the coupled THMC processes of concern. This presentation describes the approach and status of a benchmarking and code intercomparison effort currently underway, supported by the U. S. Department of Energy's Geothermal Technologies Program. This study is being closely coordinated with a parallel international effort sponsored by the International Partnership for Geothermal Technology (IPGT). We have defined an extensive suite of benchmark problems, test cases, and challenge problems, ranging in complexity and difficulty, and a number of modeling teams are applying various simulation tools to these problems. The descriptions of the problems and modeling results are being compiled using the Velo framework, a scientific workflow and data management environment accessible through a simple web-based interface.

This study employs a 2-D coupled energy/mass balance and flow model (Plummer and Phillips, 2003) to assess the magnitudes of temperature and precipitation change that could have sustained the glacier in mass-balance equilibrium at its maximum extents during the penultimate (MIS 6 or Bull Lake) glaciation and the last glacial maximum (MIS 2 or Pinedale). Variable substrate effects on glacier flow and ice thickness make the modeling somewhat more complex than in geologically simpler settings. Model results indicate that a temperature depression of about 6.4 degrees C compared to the modern (1971-2000AD) would have been necessary to sustain the 26 km-long Snowmass Creek glacier in mass balance equilibrium during the Bull Lake glaciation, assuming no change from the modern in precipitation amount or seasonality. Uncertainty in the modeling is about 1 degrees C. A 50 percent increase or decrease from modern precipitation would have been coupled with 4.8 degrees C and 8.8 degrees C Bull. Lake temperature depressions respectively. The maximum extent of the glacier during MIS 2 or Pinedale glaciation is somewhat less clear. Moraines confidently assigned to the Pinedale glaciation indicate a temperature depression of about 6.1 degrees C, assuming no change in precipitation. An intermediate set of moraines which may be Pinedale in age, would suggest a Pinedale temperature depression very close to that of the Bull Lake glaciation. These Pinedale temperature depression estimates are comparable to those obtained using the same model in three other Colorado ranges (5.5-6.8 degrees C with no change in precipitation) and slightly less than those previously obtained using a variety of other paleoglaciological methods (6.4 to 8.5 degrees C with no change in precipitation). The Bull Lake climate estimates are the first we are aware of for the Colorado Rocky Mountains.

Nevertheless, shale gas is facing strong opposition from environmental nongovernmental organizations. Although these organizations have greatly exaggerated the potential negative environmental impacts of shale gas and shale oil, methane leakage and contamination of groundwater and surface water by flowback and produced waters are serious concerns. These contamination pathways are not unique to shale gas and shale oil, and they are manageable.

For example, the original HRA method, a Technique for Human Error Rate Prediction (THERP) [1], features a set of simplified scenarios that match key actions primarily performed by reactor operators. However, actions taken in a nuclear power plant control room do not in all cases generalize to the types of actions performed elsewhere. As such, it can be challenging to extrapolate these scenarios to other domains like the petroleum industry. Moreover, the data basis for these nuclear centric actions may not match other industries. This mismatch can lead to questions about the non-nuclear validity of the human error probabilities (HEPs) derived from the HRA methods. However, it's important to note that the data in THERP, which has also served as the foundation for many other methods, was originally collected from nuclear weapons assembly work and later generalized to nuclear power. It is therefore reasonable to assume that with careful consideration, existing HRA methods and their underlying quantitative bases could reasonably be extrapolated to match other industries like oil and gas.

This will be accomplished through the introduction of modern high-fidelity computational software and protocols, with appropriate new Verification and Validation (V&V) protocols, over the next 12-18 months. Stochastic and deterministic transport theory based reactor physics codes and nuclear data packages that support this effort include MCNP5[1], SCALE/KEN06[2], HELIOS[3], SCALE/NEWT[2], and ATTILA[4]. Furthermore, a capability for sensitivity analysis and uncertainty quantification based on the TSUNAMI[5] system has also been implemented. Finally, we are also evaluating the Serpent[6] and MC21[7] codes, as additional verification tools in the near term as well as for possible applications to full threedimensional Monte Carlo based fuel management modeling in the longer term.

The most important feature of SC-HTGR and MHTGR design, which is the name sake of the reactor, is a high outlet temperature. The high outlet temperature lends this design of reactor to special applications outside the scope of current reactor designs, namely high temperature process heat for industrial uses. The key to this design is to find a suitable heat exchanger to provide the required heat transfer while exhibiting the necessary performance required for use with a nuclear reactor. This paper presents and compares many of the current and advanced designs of heat exchangers to determine its feasibility in the application of a Rankine cycle plant.

As part of this study, specific fuel cycle options are being analyzed in order to provide data that can be used in assessing the performance of alternative fuel cycles. One of the requirements of the study is that the fuel cycle options considered in the study must comprehensively represent the entire range of potential fuel cycle performance. To meet this goal for conducting this study, a set of fundamental guiding principles were developed that have the capability to distinguish the performance between various fuel cycle options.

The current eigenvalue calculation bias for the 60-fuel-element critical configuration is approximately 1% above the benchmark value [1]. As the NRAD benchmark was the first, and only, benchmark to include a significant quantity of erbium, it was initially thought that additional evaluations of experiments containing erbium might facilitate the identification of any potential errors in erbium cross section data.

Contrary to the parallel or countercurrent flow PCHE, the temperature profile of crossflow PCHE is two-dimensional, thus, is not simple to analyze. The crossflow PCHE analysis code is being developed by applying analytical solution of single-pass, both unmixed fluids crossflow heat exchanger [1]. However, the experimental data for the code validation is not available. Instead of experimental data, the CFD simulation result would be used for the code validation. In this respect, the objective of this paper is to generate the CFD simulation results for the crossflow PCHE which will be used to validate the crossflow PCHE analysis code. Numerical study using commercial CFD code, CFX-13 [2], was performed to investigate the temperature profile of crossflow PCHE for advanced SMRs. Water-cooled, helium-cooled, sodium-cooled and molten salt-cooled SMRs were taken into account in the simulation. Typical operating conditions of SMRs are summarized in Table I.

The ATR began operation in 1967, and has operated continuously since then, averaging approximately 250 operating days per year. The combination of high flux, large test volumes, and multiple experiment configuration options provide unique testing opportunities for nuclear fuels and material researchers. The ATR is a pressurized, light-water moderated and cooled, beryllium-reflected highly-enriched uranium fueled, reactor with a maximum operating power of 250 MWt. The ATR peak thermal flux can reach 1.0 x10 super(15) n/cm super(2)-sec, and the core configuration creates five main reactor power lobes (regions) that can be operated at different powers during the same operating cycle. There are nine large high-flux irradiation positions in direct contact with the fuel and 68 irradiation positions in the reactor core reflector tank. The test positions range from 1.25-12.5 cm diameter and are all 1.2 m in length. There are four primary experiment configurations that can be used in ATR. These are the static capsule, instrumented lead, pressurized water loop, and the hydraulic shuttle irradiation system (HSIS). Also at the INL are several facilities used for experiment preparation and postirradiation examination (PIE).

At the heart of pyroprocessing lies the electrorefiner (ER), which electrochemically dissolves uranium from the used fuel at an anode and deposits it on a cathode. Through normal operation of the ER, transuranics elements (such as plutonium and uranium), fission product chlorides and rare earth chlorides accumulate in the molten salt electrolyte over time. These contaminants change the physical properties of the salt, which influences the overall efficiency of the separation process. Thus, from an operational perspective, it is paramount that exact compositional information is available on the salt in order to adjust and ensure a proper operation. In addition, buildup of transuranic elements in the salt presents criticality and safeguarding concerns; this only increases the need for precise concentration data from the salt.

Access to these materials is critical for work related to material protection control and accountancy, safeguards, nonproliferation, arms control, treaty verification, and nuclear forensics. Unfortunately, recent SNM consolidation activities in the United States and around the world have reduced the ability of scientists and engineers to access these materials and perform realistic research and development experiments in support of nuclear nonproliferation. Lack of access has also negatively impacted emergency responder organizations, reducing or in some cases eliminating their ability to perform field training exercises using their equipment and practicing their techniques under realistic scenarios.

This particular design is being discussed separately as its design leads to higher heat transfer coefficients than several of its competitors. The hot and cold legs may both have fins, or only one side may have fins. In the case of the High Temperature Gas Cooled Reactor (HTGR), since the helium hot side has a lower heat transfer coefficient than does the water side there is no need to have fins on the water secondary side. Because of the benefits of this design, the offset fin HX warrants further investigation.

Substantial efforts on modeling and simulation have been performed to assist in the test design, experiment control, qualification of measured data, and quantification of test conditions [1,2]. The predicted temperatures at thermocouple locations are used in combination with statistical analysis methods for both improving calibration of the thermal model and qualification of the measured data. The calculated fuel temperatures are used for validation of the fission product transport and fuel performance simulation models. Because of the crucial roles of the simulation results in ensuring achievement of the program objectives, accurate determination of the model uncertainties is required. This paper focuses on uncertainty quantification of calculated temperature for the first experiment, AGR-1.

What differentiates the RISMC approach from traditional probabilistic risk assessment (PRA) is the concept of a safety margin. In PRA, a safety metric such as core damage frequency (CDF) is generally estimated using static fault-tree and event-tree models. However, it is not possible to estimate how close we are to physical safety limits (say peak clad temperature) for most accident sequences described in the PRA.

As with most technologies, these potential performance improvements come with a variety of challenges to bringing advanced designs to the marketplace. There are technical challenges in material selection and thermal hydraulic and power conversion design that arise particularly for higher temperature, long life operation (possibly >60 years). The process of licensing a new reactor design is also daunting, requiring significant data collection for model verification and validation to provide confidence in safety margins associated with operating a new reactor design under normal and off-normal conditions.

Specifically, the thermal diffusivity, thermal expansion coefficient, and specific heat capacity have been measured for Alloy 617 over a range of temperatures, allowing calculation of thermal conductivity up to 1000 degree C. It has been found that the thermal conductivity of Alloy 617 exhibits significant deviation from monotonic behavior in the temperature range from 600 degree C to 850 degree C, the temperatures of interest for most heat transfer applications. The non-linear behavior appears to result primarily from short-range order/disorder phenomena known to occur in the Ni-Cr system. Similar deviation from monotonic behavior was observed in the solid solution Ni-Cr-W Alloy 230, and lesser deviations were observed in iron based Alloy 800H and an austenitic stainless steel. Measured thermophysical property data are provided for four different heats of Alloy 617, and it is shown that property variations between the four different heats are not significant. Measurements were also obtained from Alloy 617 that was aged for up to 2000 h at 750 degree C, and it was found that this aging treatment does not significantly influence the thermophysical properties.

The steady-state heat conduction equation was solved in three-dimensional space using INL's MOOSE finite element software, with which spacial mesh adaptivity was used to resolve interfacial widths down to several nanometers while investigating bubble sizes up to a micrometer. Three critical parameters were systematically varied: the intergranular bubble radius, the fractional grain boundary bubble coverage, and the Kapitza resistance of the intact grain boundary. Using the simulation results, a mathematical model dependent on each of these parameters was developed to describe the effective Kapitza resistance. Furthermore, we illustrate how this model can be implemented in a fuel performance code to predict the temperature profile of a cylindrical fuel pellet.

However, the processes of kerogen maturation and hydrocarbon transport and storage are still poorly understood. Some empirical relations have been developed to relate the increase in elastic modulus with increasing maturity. A systematic study of the cause for this increase in elastic modulus is still lacking, and information about seismic and mechanical properties of kerogen and its alteration products is scarce. Consequently, any rock models must rely on anecdotal or extrapolated data about various types of kerogen. Our experiments address this paucity of data by grain-scale modulus measurements coupled with careful field emission scanning electron microscopy (FESEM) microstructural assessments on organic rich Bakken formation shale samples with a range of maturities. Carefully acquired and detailed FESEM images help to understand the microstructural controls on the reduced (nanoindentation) Young's modulus of minerals, clay particles, and kerogen matter with maturity in naturally matured shales. Using hydrous pyrolysis, we further investigate the cause for change in modulus with maturity and the mobility of the pyrolized organic matter. In naturally matured shale samples, we find a direct relationship between the reduced Young's modulus and the total organic content or hydrogen index. Significant lowering of Young's modulus is observed after hydrous pyrolysis due to bitumen generation. We measured modulus of the extruded bitumen to be less than 2 GPa. The presence of bitumen comingled with the organic matter also reduces its modulus, in excess of 30%. These results are critical to help understand how organic-rich sediments evolve with burial and maturation. The modulus measurements can be used for modeling modulus variations during maturation.

Such large amounts of information can be difficult to organize for extracting useful information. Furthermore, it is not often sufficient to merely calculate a quantitative value for the risk and its associated uncertainties. The development of risk insights that can increase system safety and improve system performance requires the interpretation of scenario evolutions and the principal characteristics of the events that contribute to the risk. For a given scenario dataset, it can be useful to identify the scenarios that have similar behaviors (i.e., identify the most evident classes), and decide for each event sequence, to which class it belongs (i.e., classification). It is shown how it is possible to accomplish these two objectives using the Mean-Shift Methodology (MSM). The MSM is a kernel-based, non-parametric density estimation technique that is used to find the modes of an unknown data distribution. The algorithm developed finds the modes of the data distribution in the state space corresponding to regions with highest data density as well as grouping the scenarios generated into clusters based on scenario temporal similarities. The MSM is illustrated using the data generated by a DET algorithm for the analysis of a simple level/temperature controller and reactor vessel auxiliary cooling system.

We test the hypothesized "bookshelf" faulting model and find that the normal faults in the Centennial tectonic belt do not accommodate distributed dextral shear. Instead, GPS data reveal that rapid extension in the Centennial tectonic belt adjacent to the much more slowly deforming region of the Snake River Plain drives right-lateral shear between them at rates of 0.3-1.5 mm yr (super -1) . GPE variations support gravitational collapse at a higher rate in the Centennial tectonic belt due to higher topography than in eastern Snake River Plain, which has lower GPE variations due to its low-relief, flat topography and a denser crustal composition. Surface velocity gradients observed in GPS data across the 40-45-km-wide Centennial shear zone reveal distributed deformation due to strike-slip faulting, distributed simple shear, regional-scale rotation, or some combination thereof. In the Centennial shear zone, the fastest lateral shearing is closest to the Yellowstone Plateau, where fault plane solutions with components of right-lateral strike slip are documented within a NE-trending zone of seismicity. Here, two Basin and Range normal faults have Holocene and late Pleistocene slip along their segments that suggest they each may have linked under right-lateral shear. We also propose that right-lateral strike-slip motion may be accommodated on existing NE-trending faults.

Fracture strength degraded continuously over the 10 days of the study for all three binders studied: PEG binder (Carbowax 8000), microcrystalline wax (Mobilcer X) and styrene-acrylic copolymer (Duramax B1022) but the fracture strength of Duramax B1022 degraded the least. For instance, for several hours after mixing Carbowax 8000 with MA-MOX, the fracture strength of a pellet was reasonably high and pellets were easily handled without breaking but the pellets were too weak to handle after 10 days. Strength measured using diametral compression test showed that strength degradation was more rapid in pellets containing 1.0 wt.% Carbowax PEG 8000 compared to those containing only 0.2 wt.%, suggesting that irradiation not only left the binder less effective but also reduced the pellet strength. In contrast the strength of pellets containing Duramax B1022 degraded very little over the 10 days period. It was suggested that the styrene portion present in the Duramax B1022 copolymer provided the radiation resistance.

It is known that flat-plates are susceptible to mechanical excitation under periodic loadings. In the presence of leading edge effects or bluff-body wakes that impart energy of a periodic nature, the vibrational modes of the plates may be matched, inducing resonance and amplification of the deflections and stresses. In the worst case, these stresses may lead to high-cycle fatigue failure of either the fuel plates or other components. Due to the complex nature of the flows, empirical formulae do not have the fidelity to capture the interaction between components or the exacerbation of the vibration due to resonance effects. To accurately capture this level of interaction, the computation of the comprehensive flow field must be directly coupled to the computation of the mechanical domain. In the past, this type of analysis was too complex to perform on a meaningful scale.

The graphite annulus remained basically the same for all experimental programs while the contents of the central cavity were adjusted according to the type of reactor being investigated. From 1992 to 1996, PROTEUS was configured as a pebble-bed reactor (PBR) critical facility and designated as HTR-PROTEUS. Seventeen critical configurations were assembled and various reactor physics experiments were performed, including criticality, differential and integral control rod and safety rod worths, kinetics, reaction rates, water ingress effects, and small sample reactivity effects.

For the last eight years the USDOE Office of Nuclear Energy and Technology (NE) has funded the development of a Fuel Cycle Cost Basis Report and Data Base for use by fuel cycle analysts. The last such document was published in December of 2009 as INL/EXT-07-12107 and is available on the Web at URL: www.inl.gov/technicalpublications/Documents/453 6700.pdf. This abstract describes a new document which updates the above-cited 2009 report for those fuel cycle steps and reactor types for which the economics has changed or that did not appear in the 2009 version. A comprehensive table at the beginning of the report lists the 30+ fuel cycle modules and the selected ranges for their unit costs. When combined with reactor characteristics and fuel cycle material balance information, the levelized unit cost of electricity (LCOE) can be calculated for candidate fuel cycles. This unit cost information for fuel cycle steps and reactor/transmuter systems will be used in the ongoing evaluation of fuel cycle options selected by DOE-NE for future research and development funding. The same data should also prove useful to nuclear industry and academic economic analysts and to non-proliferation policy analysts in the National Nuclear Security Administration (NNSA).

These uncertainty modules show the best estimate code results with uncertainty bounds, code to data comparisons (bias), code to data uncertainty comparisons (coverage ratio) and precision of code predictions (standard deviation). They are flexible to use various probability distributions (flat, binominal, triangle, etc), sampling functions (such as Wilks and Guba) and log files for tracking the computer runs. These modules are tested with the NUPEC's BFBT database, including critical power data (Table II). The results of new uncertainty modules are promising for using various applications and further development.

The functionality of the module has been tested simulating the previously explained benchmark. Since the goal of this paper focuses on me new tool only, the convergence of the code has not been pushed to exactly match the benchmark results. A previous publication has already demonstrated the convergence trend for this particular benchmark. The reported case shows that all the modules in PHISICS work with a multi-cycle simulation. SHUFFLE was designed to give PHISICS the ability to simulate fuel management and perform multi-cycle simulations. Since this capability had been unavailable before, it is an important development step for PHISICS to become a valuable tool also for fuel cycle studies and optimization. Currently it is possible to perform multi cycle full core analysis including accounting for the thermal-hydraulic feedback by the coupling with RELAP-5. PHISICS and RELAP5-3D are moving toward becoming a full nuclear reactor design and analysis tool.

The framework was implemented in MarmotViz, a Para View plug-in, and supports the use of generalized ROI identification algorithms, feature matching and tracking algorithms, and illustrative effects. This implementation incorporated a gradient-based ROI identification routine, and a novel, adaptive, volume-based feature matching algorithm. Several illustrative visualization effects were implemented to demonstrate the use and utility of this framework, including feature coloring, selective visibility, feature smoothing, tube outlines, feature halos, speedlines, and strobe silhouettes. Future work will expand upon the basic algorithms developed here to improve functionality and robustness over a wider range of flow situations. In particular, an event detection scheme would provide the flexibility to better address the complex behavior of features found in modern flow simulations.

This is realized via a graphical tool that both assists the user generating the plant layout and allows performing an online monitoring of the simulation results. Another step forward in the development of the RAVEN project has been presented here. The preliminary analysis of SVM has revealed a great potentiality in reducing of computational time and increasing the accuracy of failure probability estimation. The implementation of this technique is currently ongoing, and we are planning to illustrate preliminary results during the ANS meeting.

In particular, the software structure and all the components that are involved in the computation have been presented, including system simulator (i.e., RELAP-7) and the control logic, characterized by a monitoring system and on-line control of selected parameters. An example of PRA analysis has been also presented for a SBO-like case for a simplified PWR loop. The description of the implementation for such case demonstrates how the flexibility of the software framework provides the basic tools to perform Dynamic PRA, uncertainty quantification and plant control. Next capabilities, to be implemented to RAVEN and that are currently under development, include dynamic event tree generation, adaptive sampling and more advanced data mining algorithms.

The results are compared with those calculated from the RELAP-5 code. The basic framework to perform the coupled calculations has been developed with the Mammoth code. The future work includes extending the framework to perform transient calculations such as reactivity initiated accident calculations. The future work also includes realizing fully coupled calculations of RELAP-7/RattleSnake by integrating all of the physics into one system for better convergence. The thermal-hydraulics calculations can be enhanced through the sub-channel model with mixing or the completely three-dimensional computational fluid dynamics model. Correspondingly, the capability of RattleSnake can be fully explored with the fuel-resolved transport calculation.

In PRA, a safety metric such as core damage frequency (CDF) is generally estimated using static fault-tree and event-tree models. However, it is not possible to estimate how close we are to physical safety limits (say peak clad temperature) for most accident sequences described in the PRA.

A well-known advantage of the JFNK method is that it does not require explicitly computing and storing the Jacobian matrix during Newton nonlinear iterations. Our approach further enhances the JFNK method by utilizing physics-based, block preconditioning and a multigrid algorithm for efficient inversion of the preconditioner. This preconditioning strategy accounts for self- and optionally, cross-coupling between primary variables using diagonal and off-diagonal blocks of an approximate Jacobian, respectively. Numerical results are presented demonstrating the efficiency and massive scalability of the solution strategy for reactive transport problems involving strong solution-mineral interactions and fast kinetics. We found that the physics-based, block preconditioner significantly decreases the number of linear iterations, directly reducing computational cost; and the strongly scalable algebraic multigrid algorithm for approximate inversion of the preconditioner leads to excellent parallel scaling performance.

In this study substantial osmotic strengths of SPS are measured with freezing point osmometry and were demonstrated to induce competitive fluxes at high salt concentrations on a laboratory-scale FO unit utilizing a flat sheet cellulose triacetate (CTA) membrane. Under the experimental conditions the SPS degrades the CTA membrane; however experiments with polyamide reverse osmosis (RO) membranes display stability towards SPS. Once the draw is diluted the major fraction of the switchable polarity solvent can be mechanically separated from the purified water after polar to nonpolar phase shift induced by introduction of 1atm carbon dioxide to 1atm of air or nitrogen with mild heating. Trace amounts of SPS can be removed from the separated water with RO in a process that avoids solution concentration polarization. The separated nonpolar phase can be regenerated to a full strength draw and recycled with the re-addition of 1atm of carbon dioxide.

Commercially obtained hexachlorocyclotriphosphazene was reacted with the sodium salt of 4-ethylhydroxybenzoate to yield hexa(4-ethylcarboxylatophenoxy)phosphazene. Hydrolysis, followed by neutralization with NaOH or LiOH of the resulting acidic moieties yielded water soluble sodium and lithium phosphazene salts, respectively. Degrees of dissociation were determined through osmometry over the range of 0.05-0.5m, giving degrees of 3.08-4.95 per mole, suggesting a high osmotic potential. The Li salt was found to be more ionized in solution than the sodium salt, and this was reflected in FO experiments where the Li salt gave higher initial fluxes (7l/m2h) as compared to the sodium salt (6l/m2h) at identical 0.067m draw solution concentrations at 30 degree C. Longer term experiments revealed no detectable degradation of the salts; however some hydrolysis of the cellulose acetate membrane was observed, presumably due to the pH of the phosphazene salt draw solution (pH=8).

An eddy covariance system was deployed for approximately one month near a bubbling spring and measured net CO (sub 2) fluxes from -74 to 1147gm (super -2) d (super -1) . An inversion of measured eddy covariance CO (sub 2) fluxes and corresponding modeled source weight functions mapped the surface CO (sub 2) flux distribution within and quantified CO (sub 2) emission rate (24.9t d (super -1) ) from a 0.05km (super 2) area surrounding the spring. Soil CO (sub 2) fluxes (<1 to 52,178gm (super -2) d (super -1) ) were measured within a 0.05km (super 2) area of diffuse degassing using the accumulation chamber method. The estimated CO (sub 2) emission rate from this area was 49t d (super -1) . A carbon mass balance approach was used to estimate dissolved CO (sub 2) discharges from contributing sources at nine springs and the Soda Springs geyser. Total dissolved inorganic carbon (as CO (sub 2) ) discharge for all sampled groundwater features was 57.1t d (super -1) . Of this quantity, approximately 3% was derived from biogenic carbon dissolved in infiltrating groundwater, 35% was derived from carbonate mineral dissolution within the aquifer(s), and 62% was derived from deep source(s). Isotopic compositions of helium (1.74-2.37 R (sub a) ) and deeply derived carbon (delta (super 13) C nearly equal 3 ppm) suggested contribution of volatiles from mantle and carbonate sources. Assuming that the deeply derived CO (sub 2) discharge estimated for sampled groundwater features ( approximately 35t d (super -1) ) is representative of springs throughout the study area, the total rate of deeply derived CO (sub 2) input into the groundwater system within this area could be approximately 350t d (super -1) , similar to CO (sub 2) emission rates from a number of quiescent volcanoes.

The new velocities reveal that the clockwise rotations, relative to North America, seen in Oregon and western Washington from earlier GPS observations, continue to the east to include the Snake River Plain of Idaho and south into the Basin and Range of northern Nevada. Regional-scale rotation is attributed to gravitationally driven extension in the Basin and Range and Pacific-North America shear transferred through the Walker Lane belt aided by potentially strong pinning below the Idaho Batholith. The large rotating section comprising eastern Oregon displays very low internal deformation rates despite seismological evidence for a thin crust, warm mantle, organized mantle flow, and elevated topography. The observed disparity between mantle and surface kinematics suggests that either little stress acts between them (low basal shear) or that the crust is strong relative to the mantle. The rotation of the Oregon block impinges on Washington across the Yakima fold-thrust belt where shortening occurs in a closing-fan style. Elastic fault locking at the Cascadia subduction zone is reevaluated using the GPS velocities and recently published uplift rates. The 18 year GPS and 80 year leveling data can both be matched with a common locking model suggesting that the locking has been stable over many decades. The rate of strain accumulation is consistent with hundreds of years between great subduction events. Abstract Copyright (2012), . American Geophysical Union. All Rights Reserved.

It was demonstrated that individual fission product chloride salts were absorbed by zeolite-A in a solid-state process. As a result, recycling of LiCl-KCl appears feasible via adding a zone-freezing technique to the current treatment process. Ternary salt molten-state experiments showed the limiting kinetics of CsCl and SrCl(2) sorption into the zeolite. CsCl sorption occurred rapidly relative to SrCl(2) with no observed dependence on zeolite particle size, while SrCl(2) sorption was highly dependent on particle size. The application of experimental data to a developed reaction-diffusion-based sorption model yielded diffusivities of 8.04 X 10(-6) and 4.04 X 10(-7) cm(2)/s for CsCl and SrCl(2), respectively. Additionally, the chemical reaction term in the developed model was found to be insignificant compared to the diffusion term.

To elucidate how cold water injection may affect a fractured rock reservoir, we show results of calculations of fluid flow, heat transport and geomechanical deformation for thermal stimulation of simplified models of fractured rock reservoirs. When fractures are assumed dilate freely, results demonstrate that many fold increases in injectivity can occur. For realistic flow and heat transport parameters, where the number of interconnected fractures that conduct flow away from a well is on the order of 10 to 100, a 30-day cold water injection causes increases in injectivity of a factor of 2 to 4, with larger increases associated with fewer fractures. Changes of similar magnitude were observed in the cold water injection tests at the Hellisheidi field, SW-Iceland. The large changes in fractured rock transmissivity that can be produced by contraction of cooled rock can easily dominate the effect of increasing fluid viscosity, and dramatically decrease the pressure gradient required to accommodate a specified flow. The region of dramatically increased transmissivity effectively reproduces the effect of a very large well bore, with a flat spot in the pressure vs. distance curve that extends through the cooled region. The change in the wellhead pressure with time is thus a function of (1) the shape of the initial fluid potential drawdown curve and (2) the rate of propagation of the cooling front along that curve. As with well tests in fractured rock, the injectivity changes associated with thermal stimulation can therefore be diagnostic of those conditions. The assumption that reservoir fractures may dilate freely is most likely to hold when propagation of the thermal front is slow and the duration of the thermal stimulation is short. In that case, the stress formerly supported by the contracting region may be entirely supported by the surrounding rock. Where that stress is transmitted to a more distal region of the fractured rock reservoir, however, permeability may decline. 2-D and 3-D simulations of coupled fluid flow, heat transport and geomechanical deformation are presented to illustrate how injectivity may be affected when such stresses are considered.

EGS augments natural thermal reservoirs within the crust that lack either the permeability or hydrothermal water necessary for power production using traditional geothermal power plants. Typically, high-temperature systems are found in regions of high strain rates and geothermal gradients, such as the basin and range province. EGS has the potential to access the stored heat in regions with lower strain rates and non-ideal primary or secondary permeability. Recent boreholes drilled to a depth of 2 km in the hotspot project have reached massive welded ashflow tuffs that potentially represent one flow unit. Borehole scans reveal very little fracturing, supporting the use of the tuff unit as an EGS test site. We present an analytical solution using production targets of approximately 63 l/s (1000 gpm) for 20 years that provides theoretical fracture spacing, apertures, flow path lengths, and production rates that an EGS system would need to produce power in the snake river plain (SRP) in southern Idaho. The solution does not consider the thermomechanical properties of the reservoir that control the propagation of fractures through the unit at a given depth, thus we consider prior testing performed on tuffs. Together, the model and tuff properties allow us to give a range of possible reservoir geometries to be expected when fracturing the unit, as well as an estimate of potential power output. The work presented here provides a low-cost and quick exploratory method of testing regions for their potential as enhanced geothermal fields using basic geologic information of the site.

However, when applying the suite of traditional geothermometers, diverse temperature estimates result because 1) each geothermometer utilize only a subset of the available water chemical composition data, and 2) they do not explicitly account for many composition altering physicochemical processes along its flow path. Multicomponent equilibrium geothermometry (MEG) has an advantage over traditional geothermometers in its ability to use a complete chemical analysis of a water sample for temperature prediction. Nevertheless, the uncertainty associated with MEG estimated temperature relies in part on a correct understanding of mineral-water interactions occurring at depth in reservoir and proper quantification of composition altering processes along its flow path. Laboratory experiments simulating reservoir conditions (e.g., T and P) is one approach for understanding mineral-water interactions and quantifying composition altering processes occurring during fluid migration. As part of project to develop approaches for MEG, we are conducting a series of water-rock interaction experiments at 200-250 degrees C using 1-liter stirred Parr bench-top reactors. Representative reservoir rock samples from Raft River Geothermal area in Idaho were crushed to different grain-sized fractions and reacted separately with synthetic geothermal fluids for >2 months. Fluid samples were extracted at different times to evaluate the chemical evolution of system and to test the accuracy and uncertainty in temperature estimates with MEG. Preliminary results based on water compositions in association with likely mineral assemblage in these experiments demonstrate that with the increasing extent of reaction over time, the temperatures estimated with MEG approach the experimental temperature with decreasing uncertainty. Additional experiments with the goal of simulating some of the composition altering chemical and physical processes are planned. We expect that these water-rock interaction experiments simulating reservoir and flow path processes will allow us to constrain MEG temperature estimates with reduced and quantifiable uncertainty.

Down valley ice limits are recorded by well-preserved moraines in valleys radiating from the 4000 m-high summit ridge of the massif. Valleys on NW-to-NE aspects of the massif hosted five individual valley glaciers up to 3.7 km long. On the SW- and S-facing slopes there is evidence for a more extensive Pleistocene transection glacier system terminating in three valleys, with a maximum glacier length of 8.6 km. To better understand the chronology of glaciation of the massif, and investigate the climate responsible, we used a dual component 2-D energy/mass balance and ice flow model developed by Phillips and Plummer (2003). Initial modeling was undertaken varying only year-round temperatures from the modern, not changing precipitation or seasonality. We were unable to fit the best-preserved and most conspicuous moraines in each valley with a single temperature depression, but were able to match all of these moraines and less conspicuous moraine sets in several valleys with one-of-two temperature depressions. A temperature depression of 5.5 degrees C from modern fits the distinct terminal moraines in North French Creek on the NE side of the massif and in the East and West Forks of Beaver Creek on the SW side. A temperature depression of 4.25 degrees C fits the most distinct moraine in the Bottomless Pit immediately N of the summit of Pike Peak as well a smaller unnamed glacial valley on the NW side of the massif, as well as smaller moraine complexes up valley from the main moraines in the French and Beaver Creek valleys. We have found no clear evidence of moraines that might have been associated with a 5.5 degrees C temperature depression in the three valleys where the main moraines were well fit by the lesser temperature depression. It appears, then, that there is moraine evidence for two distinct advances or standstills of ice on the massif associated with different temperature depressions. No numerical data is available for the moraines and as a result, we are uncertain whether the two represent separate glaciations (Bull Lake and Pinedale) or whether they date from a single glacial period (Pinedale).

Geologic dating of the record of these glaciers provides new insight on the timing of glaciation, and provides the chronological framework for comparisons of paleoclimate across the Northern Rocky Mountains. Boulder samples along the left lateral sector of the terminal moraine in South Fork Deep Creek Canyon were collected for cosmogenic (super 10) Be exposure dating and yielded an error-weighted mean exposure age of 16.7+ or -0.7 ka. This exposure age is consistent with others from terminal moraines elsewhere in the northern Absaroka Range, and consistent with previous suggestions that mountain glaciers in this region began retreating as many as 3 kyr after the onset of global deglaciation. To infer climate conditions that accompanied the last glaciation in the northern Absaroka Range, a 2-D, numerical glacier model was applied to three glacial valleys. Modeling experiments indicate that, if precipitation was at or near modern, then a temperature depression of approximately 8 degrees C accompanied the time of moraine deposition. These model results along with others from ranges elsewhere in the Rocky Mountains reveal a trend of greater temperature depressions with latitude during the last glaciation, consistent with regional-scale climate models.

Although many glaciers in the northernmost ranges of this region interacted with southern lobes of the North American ice sheets, some formed discrete valley and piedmont glaciers. The records of these glaciers provide an opportunity to understand climate change during the culmination of the last glaciation and subsequent deglaciation, especially in places where the timing of mountain glaciation can be precisely limited. In the Lewis Range of northwestern Montana, a discrete glacier occupied the east flowing Cut Bank Creek valley and deposited a broad, hummocky terminal moraine on the piedmont. Cosmogenic (super 10) Be exposure ages of this moraine indicate that the glacier was at or near its maximum extent for as many as 4000 yr after the start of global deglaciation, similar to glaciers in other ranges of the northern Rocky Mountains. Temperature and precipitation at the time of terminal-moraine deposition were assessed using a 2-d, numerical model of steady state mass balance and ice flow. Model results indicate that, if precipitation was near modern at the time of moraine deposition, then a temperature depression of ca. 9 degrees C sustained the glacier at its maximum extent. This result is in contrast to the >10 degrees C temperature depression and strong reduction in precipitation during the Last Glacial Maximum yielded by regional and global-scale climate models. However, the regional signal of a late onset of deglaciation in the northern Rocky Mountains relative to North American ice sheets has been explained by increased precipitation in the region after the Last Glacial Maximum. We propose that moderate cooling compared to the Last Glacial Maximum and near-modern precipitation were sufficient to sustain mountain glaciers at their maximum extent until as late as 15 ka, and that retreat of mountain glaciers was initiated by regional warming.

The governing equations and material models applicable to particle fuel and implemented in BISON are outlined. Code verification based on a recent IAEA benchmarking exercise is described, and excellent comparisons are reported. Multiple TRISO-coated particles of increasing geometric complexity are considered. The code's ability to use the same algorithms and models to solve problems of varying dimensionality from 1 D through 3D is demonstrated. The code provides rapid solutions of 1 D spherically symmetric and 2D axially symmetric models, and its scalable parallel processing capability allows for solutions of large, complex 3D models. Additionally, the flexibility to easily include new physical and material models and straightforward ability to couple to lower length scale simulations makes BISON a powerful tool for simulation of coated-particle fuel. Future code development activities and potential applications are identified.

Previously many empirical interatomic potentials have been developed for modeling defect production and evolution in UO sub(2). However, the properties of defect clusters and extended defects are usually not fitted into these potentials. In this work nine interatomic potentials for UO sub(2) are examined by using molecular statics and molecular dynamics to assess their applicability in predicting the properties of various types of defect clusters in UO sub(2). The binding energies and structures for these defect clusters have been evaluated for each potential. In addition, the surface energies of voids of different radii and (110) flat surfaces predicted by these potentials are also evaluated. It is found that both good agreement and significant discrepancies exist for these potentials in predicting these properties. For oxygen interstitial clusters, these potentials predict significantly different defect cluster structures and stabilities; For defect clusters consisting of both uranium and oxygen defects, the prediction is in better agreement; The surface energies predicted by these potentials have significant discrepancies, and some of them are much higher than the experimentally measured values.

Activity of acetogens has been studied in many terrestrial environments, but the activity of acetogens in hot spring environments is not well understood. For this reason, acetogens in hot spring may have a wider impact on hot spring geochemical cycles and microbial populations, beyond just acetogenic activity. One method to predict the impacts of versatile metabolisms on the flow of energy and material through microbial systems is metabolic stoichiometric modeling, which extracts systemic information from molecular-level network structure and conservation relationships, depending on electron donors and acceptors in the growth environment. To test this hypothesis, an initial model has been constructed from the annotated genome of the well-studied acetogen, Moorella thermoacetica, and the output data have been sorted against various cellular strategies, including maximal efficiency of biomass yield per substrate, and substrate consumption in the presence of high exogenous concentrations of produced metabolites. Output from such models has successfully predicted substrate concentrations that yield elevated ethanol production, as opposed to acetate, when M. thermoacetica was grown on CO (sub 2) and H (sub 2.) This research has shown the utility of metabolic modeling in predicting electron donor and acceptor use and production of organic acids and alcohol in the M. thermoacetica. These types of models will help to predict the effects of acetogenic activity on the overall biogeochemistry in hot spring environments.

However, typical empirical models of fuel properties treat each of these effects separately and uncoupled. Here, we couple a fission gas release model to a model of the impact of fission gas on the fuel thermal conductivity. To quantify the specific impact of grain boundary (GB) bubbles on the thermal conductivity, we use atomistic and mesoscale simulations. Atomistic molecular dynamic simulations were employed to determine the GB thermal resistance. These values were then used in mesoscale heat conduction simulations to develop a mechanistic expression for the effective GB thermal resistance of a GB containing gas bubbles, as a function of the percentage of the GB covered by fission gas. The coupled fission gas release and thermal conductivity model was implemented in Idaho National Laboratory's BISON fuel performance code to model the behavior of a 10-pellet LWR fuel rodlet, showing how the fission gas impacts the UO(2) thermal conductivity. Furthermore, additional BISON simulations were conducted to demonstrate the impact of average grain size on both the fuel thermal conductivity and the fission gas release.

The experiments conducted in the Idaho National Laboratory's Advanced Test Reactor employ fuel compacts placed in a graphite cylinder shrouded by a steel capsule. The tests are instrumented with thermocouples embedded in graphite blocks and the target quantity (fuel temperature) is regulated by the He-Ne gas mixture that fills the gap volume. Three techniques for statistical analysis, namely control charting, correlation analysis, and regression analysis, are implemented in the NGNP Data Management and Analysis System for automated processing and qualification of the AGR measured data. The neutronic and thermal code simulation results are used for comparative scrutiny. The ultimate objective of this work includes (a) a multi-faceted system for data monitoring and data accuracy testing, (b) identification of possible modes of diagnostics deterioration and changes in experimental conditions, (c) qualification of data for use in code validation, and (d) identification and use of data trends to support effective control of test conditions with respect to the test target. Analysis results and examples given in the paper show the three statistical analysis techniques providing a complementary capability to warn of thermocouple failures. It also suggests that the regression analysis models relating calculated fuel temperatures and thermocouple readings can enable online regulation of experimental parameters (i.e. gas mixture content), to effectively maintain the fuel temperature within a given range.

Various control technologies have been developed, tested, or used over the past 50 years for control of volatile radionuclide emissions from used fuel reprocessing plants. The US DOE has sponsored, since 2009, an Off-gas Sigma Team to perform research and development focused on the most pressing volatile radionuclide control and immobilization problems. In this paper, we focus on the control requirements and methodologies for super(85) Kr and super(129) I. Numerous candidate technologies have been studied and developed at laboratory and pilot-plant scales in an effort to meet the need for high iodine control efficiency and to advance alternatives to cryogenic separations for krypton control. Several of these show promising results. Iodine decontamination factors as high as 10 super(5) , iodine loading capacities, and other adsorption parameters including adsorption rates have been demonstrated under some conditions for both silver zeolite (AgZ) and Ag-functionalized aerogel. Sorbents, including an engineered form of AgZ and selected metal organic framework materials (MOFs), have been successfully demonstrated to capture Kr and Xe without the need for separations at cryogenic temperatures.

AN - 1315705529; 17630479 AB - Engineers often face the general question of which approximations are appropriate for a given analytical task. In particular, when is a simpler model useful if a more complex model also exists? This paper explores this question in the domain of radiotoxicity relative to geologic disposal performance dose assessments. Criterion 1 requires that the simpler approach, radiotoxicity, must be calculated correctly. The concept of ingestion radiotoxic inventories is analogous to the inventory of toxic chemicals in other industries. From a decision analysis perspective, it is also somewhat analogous to the nuclear reactor safety concept of "passive safety. " This paper explains some of the issues in calculating radiotoxicity, motivated by the author's observations of errors in the literature: not accounting for radioactive progeny, misunderstanding natural "ore," and focusing on transuranic (TRU) isotopes without adequate attention to actinide decay products. For example, Th/(233)U fuel cycles do have lower amounts of TRU isotopes than U/(239)Pu fuel cycles, but that does not necessarily mean lower long-term hazard. Criterion 2 requires that the uncertainties in the more complex approach, performance dose assessments, must raise issues for the assessments' intended purposes - in which case, radiotoxic inventory may be of assistance until those issues are resolved. Performance dose assessments were developed for, and are legally the way to show, compliance with regulations, but the uncertainties are large. Less obvious is the degree to which dose assessments are applicable to other purposes - comparing fuel cycle options prior to site selection and showing the safety of a fuel cycle and waste management approach to the public. In the last sense especially, performance dose assessments are analogous to probabilistic risk assessments for nuclear reactor safety. The United States lacks a selected consensus site, selected fuel cycle approach (direct disposal versus recycling), and selected waste form. Thus, the paper does not intend to discuss all the issues with performance dose assessments but rather intends to focus on only those performance dose uncertainties that raise issues when comparing fuel cycles. Uncertainties associated with whether a generic geological environment is attractive or a specific location meets requirements are beyond the scope of this paper. Ingestion radiotoxicity correlates with heat, gamma, and inhalation radiotoxicity. Thus, options that are relatively high in ingestion radiotoxicity tend to be high in other parameters. Therefore, reduction in ingestion radiotoxicity means both that the potential source term for release is lower but also that one driving force for release (heat) is also lower. However, the most important time frames differ as heat is mainly an issue in decades and centuries after reactor discharge, but ingestion radiotoxicity is mainly an issue during longer time periods. Ingestion radiotoxicity points to the importance of actinides in long-term waste management, followed by specific fission products such as (99)Tc, (129)I, (93)Zr, (135)Cs, and (79)Se. TRU isotopes were important in four of five generic geologic environments recently studied independently with used fuel disposal experts as were the same fission products as noted from radiotoxicity - in part because waste assessments must include multiple exposure pathways including human intrusion and drilling into the waste. Dose calculations that were made for used fuel disposal may be misleading if extrapolated to disposal of only the remnants of used fuel separation because the chemistry of waste will differ. Radiotoxicity can be misleading if used to strictly rank order among individual isotopes if a specific disposal option is well known. Hybrid approaches that incorporate radiotoxicity and features of full performance assessments may have value.

While it is increasingly recognized in most industries that the human must be considered a central part of system development, it is not as readily recognized that human factors issues vary widely according to the type of system being developed, and across different parts of the system. For example, the issues involved in developing a highly manual process plant are different than those that require the operator to interface with a plant's automation system. Experience has shown that it is ineffective, risky and expensive to address this part of the design as an afterthought--a common example of bad practice. The risks associated with poor human factors can best be avoided by starting to consider humans as early as possible in the design process, and continuing them throughout. A good management process is needed to address human factors comprehensively and consistently. In most cases, concerted action is needed between different disciplines in the development team and also between teams.

In the United States, the biofuels and biopower industries are regulated by different policies and have different drivers, which impact the maximum price the industries are willing to pay for biomass. This article describes a dynamic computer simulation model that analyzes future behavior of bioenergy feedstock markets given policy and technical options. The model simulates the long-term dynamics of these markets by treating advanced biomass feedstocks as a commodity and projecting the total demand of each industry, as well as the market price over time. The model is used for an analysis of the United States bioenergy feedstock market that projects supply, demand, and market price given three independent buyers: domestic biopower, domestic biofuels, and foreign exports. With base-case assumptions, the biofuels industry is able to dominate the market and meet the federal Renewable Fuel Standard (RFS) targets for advanced biofuels. Further analyses suggest that United States bioenergy studies should include estimates of export demand in their projections, and that GHG-limiting policy would partially shield both industries from export dominance.

2014-101062 AB - Engineered precipitation in porous media involves tight, non-linear coupling between reactant transport, mixing and reaction front propagation. We conducted an experimental campaign to investigate this coupling in homogenous and heterogeneous media where reactant mixing occurs across the interface between two solutions and a mineral precipitate (CaCO (sub 3) ) is formed. Two solutions containing the components for precipitation of calcium carbonate (Ca (super 2+) and HCO (super -) (sub 3) ) were injected side-by-side into intermediate-scale flow cells packed with silica sand. Both of the individual influent solutions were undersaturated with respect to calcite. At the interface between the solutions, reactants mix by a combination of dispersive and diffusive transport, and calcium carbonate precipitation results. In homogeneous media we observed that transport across the interface decreased with time, as expected, and the volume-averaged rate of reaction decreased. When high and low permeability inclusions were placed in the path of the original mixing interface, the spatial and temporal evolution of the calcium carbonate precipitation zone showed more complicated coupling between transport and reaction kinetics. Low permeability inclusions (permeability nearly equal 25X lower than the surrounding media) caused deflection of the mixing zone. Precipitate initially forms in the center of the mixing zone. Subsequently, lateral migration of the mixing/precipitation zone was observed that resulted in the inclusion being encapsulated by carbonate mineral. Precipitate that is subsequently exposed to the undersaturated calcium containing solution persists. For a high permeability inclusion (permeability nearly equal 17X greater than the surrounding media) placed in the path of the mixing zone, the flow and mixing zone was initially focused and passed through the inclusion. Interestingly, enhanced dispersion was observed downstream of the inclusion, and the spatial extent of calcium carbonate precipitation was greater than for homogeneous media in spite of flow focusing. A fully coupled, fully implicit reactive transport model was applied to reproduce experimental observations and to gain better fundamental understanding of the complex interplay between fluid flow, transport of reactants, and reaction-induced permeability/porosity changes.

It is now well known that the conventional approach to Darcy-scale solute transport simulation tends to overestimate in situ reaction rates because the dispersion process conceptualization combines advective spreading (due to heterogeneity) and diffusive mixing in a single lumped representation. Hybrid multiscale simulation methods, which combine microscale (pore-scale) and macroscale (Darcy-scale) simulations within a single unified framework, offers the potential to address this problem by explicitly resolving local diffusive mixing as impacted by large-scale advective spreading in a computationally tractable manner. In this talk we present methods and results of a multiscale hybrid simulation approach applied to a mixing-controlled reaction at the laboratory scale. Our approach couples a Smoothed Particle Hydrodynamics (SPH) pore-scale simulator with the STOMP Darcy-scale simulator using a custom workflow management system that adaptively selects SPH sub-domains and provides the coupling between SPH and STOMP simulations seamlessly on a scalable parallel computational platform.

Successful sequestration process requires efficient and adequate monitoring of injected fluids as they migrate into the aquifer to evaluate flow path, leakage, and geochemical interactions between CO (sub 2) and geologic media. In this synthetic field scale study, we have integrated 3D multiphase flow modeling code PFLOTRAN with 3D time-laps electrical resistivity tomography (ERT) to gain insight into the supercritical (SC) CO (sub 2) plumes movement in the deep saline aquifer and associated brine intrusion into shallower fresh water aquifer. A parallel ERT forward and inverse modeling package was introduced, and related algorithms are briefly described. The capabilities and limitations of ERT in monitoring CO (sub 2) migration are assessed by comparing the results from PFLOTRAN simulations with the ERT inversion results. In general, our study shows the ERT inversion results compare well with PFLOTRAN with reasonable discrepancies, indicating that the ERT can capture the actual CO (sub 2) plume dynamics and brine intrusion. Detailed comparisons on the location, size and volume of CO (sub 2) plume show the ERT method underestimated area review and overestimated total plume volume in the predictions of SC CO (sub 2) movements. These comparisons also show the ERT method constantly overestimate salt intrusion area and underestimated total solute amount in the predictions of brine filtration. Our study shows that together with other geochemical and geophysical methods, ERT is a potentially useful monitoring tool in detecting the SC CO (sub 2) and formation fluid migrations.

Given the sensitivity of mountain glaciers to factors such as temperature, precipitation, and solar radiation, reconstructions of the history and extent of paleo-glaciers can be used to infer paleoclimate. Pine Creek Valley, located in the Absaroka Mountains in southwestern Montana, is an ideal setting for this type of research because it was occupied by a discrete valley glacier, the extent of which is precisely known during the LGM. To determine the pace and timing of ice retreat in this valley, glacially polished bedrock surfaces along the path of deglaciation were sampled at several points for cosmogenic (super 10) Be surface exposure dating. The ages obtained range from 17.9 + or - 0.8 to 13.2 + or - 0.5 ka. When combined with the reconstructed ice extent during the LGM and subsequent deglaciation, these ages yield maximum and minimum retreat rates of 3.1 m/yr and 1.1 m/yr, respectively. These values constrain how long it took the glacier to retreat into a well-defined cirque from the terminal moraines. Paleoclimate conditions for the LGM were estimated using a two-dimensional, numerical, combined energy and mass balance and ice flow model. Previous qualitative inferences of paleoclimate in southern Montana indicate climate during the local LGM was colder and drier than modern values. If precipitation values were held constant or reduced for the Pine Creek glacier, the model suggests a temperature depression of at least 8 degrees C.

Understanding the geochemical processes of CO2-fluid-rock interactions in EGS reservoirs is significant important to investigate the performance of energy extraction with CO2 instead of water as a working fluid, carbon sequestration and risk assessment. The objectives of this study: (1) to calibrate and evaluate the kinetic rate constants and specific reactive surface areas of minerals based on the batch experimental data conducted by other researchers (collaborators Kaszuba and Lo Re at the University of Wyoming); (2) to investigate the effects of CO2-fluid-rock geochemical interactions on the energy extraction efficiency, carbon sequestration, and risk assessment. A series of laboratory experiments were conducted (Lo Re et al., 2012) to investigate the geochemical reactions among water, fractured granite rocks, and injected supercritical CO2 at elevated temperatures of 250 degrees C, and pressures of 250-450 bars. The batch simulations were firstly conducted to mimic the laboratory experiments with the calibration of mineral reactive surface areas using TOUGHREACT model and parameter estimation software (PEST). Then, we performed 2-D geochemical modeling to simulate the chemical interactions among CO2, fluids, and rocks at high temperatures and pressures of EGS reservoirs. We further investigated the effects of fluid-rock interactions on the energy extraction, carbon sequestration, and risk assessment with CO2 as a heat transmission fluid instead of water for EGS reservoirs. Results of carbonate mineral precipitations suggested that the CO2 as a working fluid instead of water was favorable for EGS reservoirs on the CO2 sequestration. Our simulations also suggested that the energy extraction could be enhanced using CO2 as the transmission fluid compared to water.

The complex behavior of air-water two-phase flow in fractures has significant implications for contaminant transport in deep, fractured vadose zones. Understanding and predicting the complex physics of flow at the field scale is still limited due to the lack of physics-based numerical models, size limitations of laboratory fracture flow experiments, inadequate characterization of fracture networks and absence of efficient monitoring tools for multiphase flow in the field. In this work, we present an integrated experimental and modeling study of air-water flow dynamics in fractures and fracture networks at multiple scales of observation, ranging from single small fracture models with variable apertures, to an intermediate scale laboratory analog of a fracture network, and finally a large field scale infiltration test. The complex 3D flow dynamics, including pulsating flow and flow path switching near fracture intersections, and air-water interfacial behaviors, are simulated and discussed. The fracture flow experimental data will also be presented and discussed, and compared with the modeling results. The qualitative agreements between the numerical simulations and the experimental results clearly demonstrate the value of the mechanistically based models for sorting out the complexity of multiphase flow dynamics in unsaturated fracture networks.

The underlying assumption of geothermometry is that the shallow waters maintain a chemical signature that reflects equilibrium in the deeper reservoir. Many of the geothermometers used in practice are based on empirical observations and correlation between water temperatures and composition using a subset (typically silica, cations or cation ratios) of the dissolved constituents. An alternative approach is to use complete water compositions and equilibrium geochemical modeling to calculate the degree of disequilibrium (Saturation Index) for large number of potential reservoir mineral as a function of temperature. Key to applying this approach is to define the often unknown primary/secondary mineral assemblage controlling equilibrium in the deep reservoir and to apply develop parameter optimization approaches to estimate the likely conditions (e.g., temperature, PCO (sub 2) ) to which the water was exposed in the deep subsurface. Selection of mineral assemblages can be addressed by a combination of practical (e.g., taking into account common alteration mineral assemblages) as well as theoretical (limiting the number of minerals by the phase rule) considerations. Because the values of Saturation Indexes are a function of reaction stoichiometry, simultaneous interpretation requires that values be weighted or normalized. The approach used here is to write reaction in terms of thermodynamic components and then divide the saturation index by the total count of components in the reaction (e.g., 1 for quartz, 2 for calcite, 5 for albite, and 7 for muscovite). This approach is tested against both synthetic and field derived data sets to estimate reservoir temperatures which are compared to actual temperatures or temperatures estimated from commonly employed approaches for geothermometry.

The model was employed to understand the conditions that would be necessary to sustain valley glaciers and small mountain icecaps at their maximum extents in eight areas distributed along the crest of the range from northern New Mexico (35.8 degrees N) to northern Montana (48.6 degrees N). For each setting, model experiments yield a set of temperature and precipitation combinations that may have accompanied the local LGM. If the results of global and regional climate models are used to constrain temperature depression estimates from our model experiments, the following precipitation pattern emerges for the local LGM. In the northern Rocky Mountains in Montana and northern Wyoming, model results suggest a strong reduction in precipitation of 50% or more. In the central Rocky Mountains of southern Wyoming and Colorado, precipitation appears to have been 50-90% of modern. By contrast, precipitation appears to have been strongly enhanced in the southern Rocky Mountains of New Mexico. These results are broadly consistent with a pattern of precipitation observed in global and regional climate simulations of the LGM in the western U.S., in which precipitation was reduced in the northern Rocky Mountains but increased in the southern Rocky Mountains. This pattern may reflect a southward displacement of mean position the Pacific Jet Stream in western North America during and possibly following the LGM.

Frequency-domain induced polarization is a minimally invasive manner to measure the complex conductivity of a material over a broad range of frequencies. The real component of complex conductivity is associated with electromigration of the charge carriers, and the imaginary component represents reversible energy storage of charge carriers at polarization length scales. Quantitative relationship between frequency-domain induced polarization responses and bacterial growth and decay in porous media is analyzed in this study using a new developed model. We focus on the direct contribution of bacteria themselves to the complex conductivity in porous media in the absence of biomineralization. At low frequencies, the induced polarization of bacteria (alpha -polarization) is related to the properties of the electrical double layer surrounding the membrane surface of bacteria. Surface conductivity and alpha -polarization are due to the Stern layer of the counterions occurring in a brush of polymers coating the surface of the bacteria, and can be related to the cation exchange capacity of the bacteria. From the modeling results, at low frequencies (<10 Hz), the mobility of the counterions (K (super +) ) in the Stern layer of bacteria is found to be extremely small (4.7X10 (super -10) m (super 2) s (super -1) V (super -1) at 25 degrees C), and is close to the mobility of the same counterions along the surface of clay minerals (Na (super +) , 1.5X10 (super -10) m (super 2) s (super -1) V (super -1) at 25 degrees C). This result is in agreement with experimental observations and it indicates a very low relaxation frequency for the alpha -polarization of the bacteria cells (typically around 0.1 to 5 Hertz). By coupling this new model with reactive transport modeling in which the evolution of bacterial populations are usually described by Monod kinetics, we show that the changes in imaginary conductivity with time can be used to determine bacterial growth kinetics parameters such as the growth and endogenous decay coefficient.

The velocities reveal a slowly-deforming region within the Snake River Plain in Idaho and Owyhee-Oregon Plateau in Oregon separated from the actively extending adjacent Basin and Range regions by shear. Our results show a NE-oriented extensional strain rate of 5.6 + or - 0.7 nanostrain/yr in the Centennial Tectonic Belt and an approximately E-oriented extensional strain rate of 3.5 + or - 0.2 nanostrain/yr in the Great Basin. These extensional rates contrast with the very low strain rate within the 125 km x 650 km region of the Snake River Plain and Owyhee-Oregon Plateau which is not distinguishable from zero (-0.1 + or - 0.4 X nanostrain/yr). Inversions of Snake River Plain velocities with dike-opening models indicate that rapid extension by dike intrusion in volcanic rift zones, as previously hypothesized, is not currently occurring. GPS data also disclose that rapid extension in the surrounding regions adjacent to the slowly-deforming region of the Snake River Plain drives shear between them. We estimate right-lateral shear with slip rates of 0.3-1.5 mm/yr along the northwestern boundary adjacent to the Centennial Tectonic Belt and left-lateral oblique extension with slip rates of 0.5-1.5 mm/yr along the southeastern boundary adjacent to the Intermountain Seismic Belt. The fastest lateral shearing evident in the GPS occurs near the Yellowstone Plateau where earthquakes with right-lateral strike-slip focal mechanisms are within a NE-trending zone of seismicity. The regional velocity gradients are best fit by nearby poles of rotation for the Centennial Tectonic Belt, Snake River Plain, Owyhee-Oregon Plateau, and eastern Oregon, indicating that clockwise rotation is not locally driven by Yellowstone hotspot volcanism, but instead by extension to the south across the Wasatch fault possibly due to gravitational collapse and by shear in the Walker Lane belt resulting from Pacific - Northern America relative plate motion.

EC provides an automated, semi-continuous, and time and space-averaged CO (sub 2) flux measurement. Also, the measurement's "intermediate" spatial scale (m (super 2) -km (super 2) ) has the potential to bridge the gap between relatively small-scale ground-based measurements (e.g., using the accumulation chamber, AC, method) and relatively large-scale satellite-based observations. We deployed and tested an EC system during two studies in an area of diffuse volcanic CO (sub 2) emissions on Mammoth Mountain, CA and near a bubbling spring in Soda Springs, ID. Half-hourly EC CO (sub 2) fluxes were measured on Mammoth Mountain during September-October 2006 and ranged from 218 to 3500 g m (super -2) d (super -1) . Maps of surface CO (sub 2) flux were simulated based on AC measurements made repeatedly on a grid over a ten-day period. Large meteorologically driven variations in surface flux distributions and emission rates (16 to 52 t d (super -1) ) were observed. Using source weight function modeling, we compared EC to AC measurements of CO (sub 2) flux. Half-hour EC CO (sub 2) fluxes were moderately correlated (R (super 2) =0.42) with AC fluxes, whereas average-daily EC and AC fluxes were well correlated (R (super 2) =0.70). We then made EC measurements of CO (sub 2) flux on Mammoth Mountain during September-October 2010, which ranged from 85 to 1766 g m (super -2) d (super -1) . Three AC soil CO (sub 2) flux surveys during this time were used to simulate maps of soil CO (sub 2) flux and estimate total emission rates. An inversion of measured EC CO (sub 2) fluxes and corresponding modeled source weight functions was carried out and recovered 58 to 77% of the CO (sub 2) emission rates estimated based on simulated AC soil CO (sub 2) fluxes within a 0.01 km (super 2) area. Spatial distributions of modeled surface CO (sub 2) fluxes based on EC and AC observations showed moderate to good correspondence (R (super 2) =0.36 to 0.70). In September-October 2011, we deployed an EC system near a bubbling spring in Soda Springs, ID and measured CO (sub 2) fluxes from -74 to 1147 g m (super -2) d (super -1) . An inversion of measured EC CO (sub 2) fluxes and modeled source weight functions mapped the surface CO (sub 2) flux distribution within and quantified CO (sub 2) emission rate (24.9 t d (super -1) ) from a 0.05 km (super 2) area surrounding the spring. This emission rate was 79% of the dissolved CO (sub 2) discharge from the spring estimated as the product of the measured concentration of dissolved inorganic carbon and spring outflow rate. Overall, the results of our investigations suggest that under appropriate terrain and atmospheric conditions, EC can serve as a valuable tool for semi-continuous monitoring and quantification of volcanic CO (sub 2) emissions from moderate size land areas.

However, glaciers can flow against the topographic gradient to cross drainage divides, reshaping fluvial drainage networks and dramatically altering discharge. In turn, these variations in discharge will be recorded by proglacial stratigraphy. Glacial-drainage capture often occurs in alpine environments where ice caps straddle range divides, and more subtly where shallow drainage divides cross valley floors. We investigate discharge variations resulting from glacial-drainage capture over the past 40 k.y. for the adjacent Ashburton, Rangitata, and Rakaia basins in the Southern Alps, New Zealand. Although glacial-drainage capture has previously been inferred in the range, our numerical glacier model provides the first quantitative demonstration that this process drives larger variations in discharge for a longer duration than those that occur due to climate change alone. During the Last Glacial Maximum, the effective drainage area of the Ashburton catchment increased to 160% of the interglacial value with drainage capture, driving an increase in discharge exceeding that resulting from glacier recession. Glacial-drainage capture is distinct from traditional (base level-driven) drainage capture and is often unrecognized in proglacial deposits, complicating interpretation of the sedimentary record of climate change.

opportunities and challenges AN - 1469625115; 2013-097422 AB - The production of hydrocarbon fluids from very low permeability rocks has been increasing at a high rate for many years, but it received little attention until production reached about 20% of US total gas production, just a few years ago, and resource reassessments indicated that addition of "first generation" unconventional gas (shale gas, tight gas and coalbed methane) could double the US technically recoverable resource. Shale gas is the most important of these resources, and by 2035 it could account for almost 1/2 of US natural gas production. Shale gas production is enabled by horizontal drilling, hydraulic fracturing and fracture propping, but despite many innovations, recovery factors are low (for shale gas recovery factors vary greatly with an average of about 20%). Based on current technology and resource estimates, hundreds of thousands of hydraulically fractured wells will be required to produce the US shale gas resource, and millions will be required worldwide. We have developed physics-based numerical models for hydraulic fracturing, fracture propping, the placement of propping particles in fracture apertures and fluid flow in propped fractures, and applied them to shale gas recovery. Most of these models are based on the discrete element models for rock deformation and fracturing coupled with a Darcy flow or pore network model for fluid flow and a continuum heat transport model. US and global first generation natural gas resources will be discussed and an overview of the technology used to produce gas from these resources will be presented with a focus on the geomechanics of shale gas production and the challenges of producing hydrocarbon fluids from very low permeability rocks. Some of our own research results will be included in the presentation.

Because of the timescales and volumes involved, it is not possible to conduct field scale experiments to measure the actual phenomenon. Geochemical transport models are useful, but without field-derived data, these models cannot provide unique solutions. Natural analogue sites for the study geologic carbon dioxide sequestration provide opportunities to bridge this gap by examining CO (sub 2) systems that have operated on time scales of centuries to millenia. Such sites provide a perspective that laboratory and field experiments (e.g., time scales of days to decades) cannot provide. One such Site is the CO (sub 2) Leak Analogue Study Site (CLASS) located in Soda Springs, Idaho, USA. At this site, CO (sub 2) and formation fluids generated by the dissolution of Paleozoic carbonates at depth are migrating and reacting with a series of shallower thoelitic basalt flows that host a fresh water aquifer. In many cases the CO (sub 2) escapes to the surface in large volumes. But in most cases the CO (sub 2) is trapped by mineralization reactions with in the aquifer and by dissolution into the groundwater. These mineralization reactions have generated a specific chemical signature within the formation fluid. This signature can be used to assess the relative impact of leaking CO (sub 2) on water-rock interactions, and provides a basis for interpreting results from field and laboratory experiments in the context of a large-scale CO (sub 2) system interacting with an overlying aquifer. Lessons learned from the work at the Soda Springs analog site have provided insight into how reactive in situ tracers can track the progress of CO (sub 2) -water-rock interactions, and preliminary results have been integrated into the risk management plan for the Big Sky Carbon Sequestration Partnership's project at Kevin Dome.

While these laboratory experiments suggest that basalt-hosted reservoirs may be ideal targets for long term CO (sub 2) disposal, little work has been done to understand the site scale impacts of commercial CO (sub 2) injections into basalt-hosted reservoirs. Among the many questions that remain open, the influence of spatially distributed formation heterogeneity is a fundamental challenge for characterizing and modeling CO (sub 2) injections into a basalt reservoir. In the work presented here, we use a Monte Carlo numerical modeling experiment of CO (sub 2) injections into a low-volume basalt reservoir--with properties based on data from the east Snake River plain (ESRP) in southern Idaho--to investigate how a priori unknown heterogeneous property distributions influence injection pressure accumulation, geomechanical changes in the target reservoir, and vertical CO (sub 2) migration. The target reservoir is modeled as a three-dimensional bimodal stochastic continuum (2.88M gridblocks) using 50 equally probable synthetic reservoirs. Supercritical CO (sub 2) is injected into each reservoir model at a constant mass rate of approximately 682,000 metric tons/year for 20 years. Results from this work suggest that 1) formation heterogeneity strongly influences the rate and magnitude of injection pressure accumulation within the first month of injection; 2) for an extensional stress regime (as exists within the ESRP), shear failure is unlikely for minimum horizontal compressive stress (S (sub h) ) greater than 60% of the vertical stress (S (sub v) ), and; 3) the mean vertical CO (sub 2) mass flux is less than 5 X 10 (super -4) kg/s at 800m depth after 20 years suggesting that carbonate precipitation rates described in the literature may be adequate to trap CO (sub 2) prior to widespread escape.

Examples include the elastic constants, sample dimensions, and crystal orientation. Extracting the parameter of interest involves performing the inverse problem, which typically entails an iterative routine that compares calculated and measured eigenfrequencies. Here, we propose an alternative method based on laser-based resonant ultrasound spectroscopy (LRUS) that uses the eigenmodes. LRUS uses a pulsed laser to thermoelastically excite ultrasound and an interferometer to detect out-of-plane displacement associated with ultrasonic resonances. By raster scanning the probe along the sample surface, an image of the out-ofplane displacement pattern (i.e., eigenmode) is obtained. As an example of this method, we describe a technique to calculate the crystallographic orientation of a single-crystal high-purity copper sample. The crystallographic orientation is computed by comparing theoretical and experimental eigenmodes. The computed angle is shown to be in very good agreement with the angle obtained using electron backscatter diffraction. In addition, a comparison is made using eigenfrequencies and eigenmodes to calculate the crystallographic orientation. It is found for this particular application, the eigenmode method has superior sensitivity to crystal orientation.

2016-031178 AB - Fractionation of the two longer-lived radioactive cesium isotopes ( (super 135) Cs and (super 137) Cs) produced by above ground nuclear tests have been measured and used to clarify the dispersal mechanisms of cesium deposited in the area between the Nevada Nuclear Security Site and Lake Mead in the southwestern United States. Fractionation of these isotopes is due to the 135-decay chain requiring several days to completely decay to (super 135) Cs, and the 137-decay chain less than one hour decay to (super 137) Cs. Since the Cs precursors are gases, iodine and xenon, the (super 135) Cs plume was deposited farther downwind than the (super 137) Cs plume. Sediment core samples were obtained from the Las Vegas arm of Lake Mead, sub-sampled and analyzed for (super 135) Cs/ (super 137) Cs ratios by thermal ionization mass spectrometry. The layers proved to have nearly identical highly fractionated isotope ratios. This information is consistent with a model where the cesium was initially deposited onto the land area draining into Lake Mead and the composite from all of the above ground shots subsequently washed onto Lake Mead by high intensity rain and wind storms producing a layering of Cs activity, where each layer is a portion of the composite.

These methods do not suit an open installation accelerator operating in an outdoor environment without the containment of a shielded building and defined release points. Radionuclides created by an open installation accelerator are immediately released upon creation and are considered diffuse and fugitive. A representative source term cannot be sampled or measured. A process was developed to estimate the radionuclide source term based on methods contained in National Council on Radiation Protection and Measurements Report 144 and the Monte Carlo N-Particle Extended model. Adjustments were made base on operational parameters and accelerator configuration. The EPA approved the use of this method as an approved alternative to those contained within the standard.

Remote sensing methods with sufficient accuracy could dramatically alter how biotic resources are monitored on both public and private lands. Idaho National Laboratory (INL), in conjunction with the University of Idaho, evaluated whether unmanned aerial vehicles (UAVs) are sufficiently accurate and more efficient than the point-frame field method for monitoring vegetative cover and bare ground in sagebrush steppe ecosystems. These values are of interest to land managers because typically there are limited natural resource scientists and funding for comprehensive ground evaluations. In this project, unmanned helicopters were used to collect still-frame imagery to determine vegetation cover during June and July 2005. The images were used to estimate percent cover for six vegetative cover classes (shrub, dead shrub, grass, forbs, litter, and bare ground). Field plots used to collect imagery and on-the-ground measurements were located on the INL site west of Idaho Falls, Idaho. Ocular assessments of digital imagery were performed using SamplePoint, and the results were compared with field measurements collected using a point-frame method. The helicopter imagery evaluation showed a high degree of agreement with field cover class values for grass, litter, and bare ground and reasonable agreement for dead shrubs. Shrub cover was often overestimated, and forbs were generally underestimated. The helicopter method took 45% less time than the field method. This study demonstrates that UAV technology provides a viable method for monitoring selective types of cover on rangelands and could save time and resources. Evaluar la cobertura vegetal es un importante factor para entender la sustentabilidad de muchos ecosistemas. Metodos de teledeteccion con suficiente precision pueden considerablemente alterar la manera en como los recursos bioticos son monitoreados tanto en propiedad privada y publica. El laboratorio Nacional de Idaho (INL), en conjunto con la universidad de Idaho, evaluaron si vehiculos aereos no tripulados (UAVs) son suficientemente precisos y mas eficientes que los metodos de campo basados en punto de referencia para monitorear la cobertura de las vegetacion y el suelo desnudo en los ecosistemas de pastizales de Artemisia. Estas evaluaciones son de interes para los manejadores de tierra ya que normalmente hay pocos cientificos dedicados al estudio de los recursos naturales asi como escasos recursos monetarios para evaluaciones integrales. En este proyecto, helicopteros no tripulados fueron usados para recolectar imagenes usadas para determinar la cobertura vegetal durante junio y julio de 2005. Las imagenes fueron usadas para estimar el porcentaje de cobertura de seis clases de cubierta vegetal (arbustos, arbustos muertos, pastos, herbaceas, hojarasca y suelo desnudo). Parcelas de campo que fueron usadas para recolectar las imagenes asi como las mediciones en campo fueron localizadas en el sitio INL al oeste de Idaho Falls, Idaho. Evaluaciones oculares de imagenes digitales fueron realizadas usando SamplePoint y los resultados fueron comparados con las mediciones de campo recolectadas usando el metodo de point-frame. La evaluacion de las imagenes recolectadas por el helicoptero mostro un alto grado de correlacion con respecto a las evaluaciones de campo para pastos, hojarasca, y suelo desnudo, y una razonable relacion para plantas muertas. Las cobertura de los arbustos fue regularmente sobrestimado y para las herbaceas fueron generalmente subestimadas. El metodo del helicoptero tomo 45% menos tiempo que el metodo de campo. Este estudio demostro que la tecnologia UAV proporciono un metodo viable para monitorear los tipos selectivos de cobertura en los pastizales y podria salvar tiempo y recursos.

16895655 AB - An often cited weakness of the Integral Fast Reactor (IFR) concept is that the chloride salt-based radioactive waste generated by its electrorefiner (ER) cannot be vitrified. Although that assertion is literally true, it is also misleading because it would be quite simple to recycle that waste's chloride and vitrify its cationic components (mostly alkali metals and fission products). Producing this alternative to Argonne National Laboratory's ceramic waste form would entail vitrification of a mixture of orthophosphoric acid, ferric oxide, and powdered ER salt with a melter able to efficiently disengage gas bub- bles, e.g., a Stir Melter. The HCl evolved by this process would be absorbed by an aqueous lithium/potassium hydroxide scrub solution, which would then be dried and recycled as fresh ER electrolyte. Because radioiodide would otherwise accumulate in the ER salt, the caustic scrub solution would occasionally be contacted with cuprous or silver chloride before recycle. This scenario's primary advantages would be much lower cost and approximately fivefold greater effective waste loading. This paper describes the experimental work supporting these contentions.

A HEX-Z partially homogenized benchmark model of the FFTF fully loaded core configuration was developed for evaluation of these measurements. Evaluated measurements include the critical eigenvalue of the fully loaded core, two neutron spectra, 32 reactivity effects measurements, an isothermal temperature coefficient, and low-energy gamma and electron spectra. Dominant uncertainties in the critical configuration include the placement of radial shielding around the core, reactor core assembly pitch, composition of the stainless steel components, plutonium content in the fuel pellets, and boron content in the absorber pellets. Calculations of criticality, reactivity effects measurements, and the isothermal temperature coefficient using Monte Carlo N-Particle version 5.1.40 (MCNP5) and ENDF/B-VII.0 cross sections with the benchmark model are in good agreement with the benchmark experiment measurements. There is little agreement between calculated and measured spectral measurements. This benchmark evaluation has been added to the International Handbook of Evaluated Reactor Physics Benchmark Experiments.

In the short term, this coupling will provide carbon-free hydrogen for upgrading increasingly lower-quality petroleum resources such as oil sands, offsetting carbon emissions associated with steam methane reforming. In the intermediate term, nuclear hydrogen will be needed for large-scale production of infrastructure-compatible synthetic liquid fuels. In the long term, there is great potential for the use of hydrogen as a direct vehicle fuel, most likely in the form of light-duty pluggable hybrid hydrogen fuel cell vehicles (HFCVs). This paper presents a review of the potential benefits of large-scale nuclear hydrogen production for energy security (i.e., displacing imported petroleum) and reduction of greenhouse gas emissions. Life-cycle benefits of nuclear energy in this context are presented, with reference to recent major publications on this topic. The status of U.S. and international nuclear hydrogen research programs is discussed. Industry progress toward consumer-grade HFCVs is also examined.

The velocities, together with geologic, volcanic, and earthquake data, reveal a slowly deforming region within the Snake River plain in Idaho and Owyhee-Oregon Plateau in Oregon separated from the actively extending adjacent Basin and Range regions by shear. Our results show a NE-oriented extensional strain rate of 5.6 + or - 0.7 X 10 (super -9) yr (super -1) in the Centennial Tectonic Belt and an approximately E-oriented extensional strain rate of 3.5 + or - 0.2 X 10 (super -9) yr (super -1) in the Great Basin. These extensional rates contrast with the very low strain rate within the 125 km X 650 km region of the Snake River plain and Owyhee-Oregon Plateau, which is indistinguishable from zero (-0.1 + or - 0.4 X 10 (super -9) yr (super -1) ). Inversions of the velocities with dyke-opening models indicate that rapid extension by dyke intrusion in volcanic rift zones, as previously hypothesized, is not currently occurring in the Snake River plain. This slow internal deformation, in contrast to the rapidly extending adjacent Basin and Range regions, indicates shear along the boundaries of the Snake River plain. We estimate right-lateral shear with slip rates of 0.3-1.4 mm yr (super -1) along the northwestern boundary adjacent to the Centennial Tectonic Belt and left-lateral oblique extension with slip rates of 0.5-1.5 mm yr (super -1) along the southeastern boundary adjacent to the Intermountain Seismic Belt. The fastest lateral shearing evident in the GPS occurs near the Yellowstone Plateau where strike-slip focal mechanisms and faults with observed strike-slip components of motion are documented. The regional velocity gradients are best fit by nearby poles of rotation for the Centennial Tectonic Belt, Snake River plain, Owyhee-Oregon Plateau, and eastern Oregon, indicating that clockwise rotation is not locally driven by Yellowstone hotspot volcanism, but instead by extension to the south across the Wasatch Fault due to gravitational collapse and by shear in the Walker Lane Belt resulting from Pacific-Northern America relative plate motion.

The results were evaluated using a curvefitting routine, and the enthalpies of individual phase transitions were determined. Individual transitions were assigned with reference to published ternary phase diagrams, and a compositional analysis for the partial transformations of each alloy allowed the first determination of the gamma-delta transition enthalpy for the ternary fuel alloys. These results agree with prior research for binary fuel alloys that found the enthalpy to be approximately 5 kJ per mole with some variation depending on the exact composition within the broad delta-UZr2 phase range. The comparable results suggest that the heat of solution for the zirconium in the ternary delta-phase is similar to that for zirconium in the binary deltaphase, which might be expected; however it is possible that the activities of Pu and Zr in the delta phase may be self-compensating.

Experiments were conducted to determine the ignition delay time (IDT) of cyclopentane using an Ignition Quality Test (IQT) device. Two sets of experiments were conducted per ASTM D6890 (with exception to charge pressure and temperature) to determine ignition delay of the fuel at atmospheric pressure for normal air (~21% oxygen) and vitiated air (13.3% oxygen) at a temperature of 530 degree C. Operation of the IQT device at a much lower pressure (1 bar) than normal operation (21.1 bar) led to very rich conditions and wetting of the stainless steel chamber walls. Catalytic effects produced small IDTs. Experiments were repeated with a modified injector to prevent wall wetting, resulting in average IDTs that are substantially longer.

NpO(2) is combined with calcium and heated to temperatures between 650 degree C and 850 degree C under argon. Three successful trials were conducted to yield a total of approximately 20 g of neptunium with purity estimated greater than 97%. The metal is needed to determine important thermal and phase properties of binary neptunium systems as well as fresh metallic fuels that simulate the compositions of recycled fuel. The process development was necessary since most of the neptunium available is present as the oxide. Future efforts are planned for understanding the process parameters in relation to neptunium purity, and for purifying the metal produced.

Investigating the atomistic details of these two processes is critical for understanding the microstructural evolution of UO2 under irradiation. Here we first use molecular dynamics simulations to investigate collision cascade induced defect production at the picosecond timescale at both 300 K and 1000 K. The energy of the primary knock-on atom is 2 keV. Based on 200+ cascade simulations, we obtain the distributions of defect clusters in terms of their compositions and sizes at both temperatures. We then use temperature accelerated dynamics to investigate the migration barriers of these interstitial and vacancy clusters and determine their mobility. Finally we examine the interaction between different types of defect clusters and discuss their opportunities of forming larger clusters at long timescales.

Dispersion type plate fuels are popular for many research and test reactors, a special class of LWRs. A typical dispersion fuel plate in a test reactor consists of three layers with the outer layers of aluminum cladding and the middle layer of aluminum alloy dispersed with U-xMo (x=7-10 in wt%) or U3Si2 fuel particles. Fuel- Matrix Interaction (FMI) layer can develop as a result of fuel fabrication and reactor irradiation. The microstructural stability of the fuel under irradiation could strongly affect the fuel performance. This work reports the microstructure characterization using TEM on the irradiated RERTR dispersion fuels. The detailed microstrucural features will be analyzed and compared with the results in literature. The impact of the observed microstructure on fuel performance will be discussed.

This paper outlines the initial steps of a fuels program to recapture the technology required to fabricate W-UO2 fuel forms for hydrogen cooled nuclear rocket applications. The results and lessons learned from a robust literature search of the ANL CERMET fuels program and the General Electric 710 programs are detailed in this study. This paper also describes an initial effort to spheroidize particles of CeO2 which are also coated with tungsten to a 40 vol.% ratio. The particles are consolidated into fuel specimens and prototypic fuel element segments via Pulsed Electric Current Sintering (PECS) and Hot Isostatic Pressing (HIPing) techniques. Comparisons are made between the microstructure and basic properties of the specimens fabricated by PECS and HIP techniques.

Implicit implementations of crystal plasticity finite element method (CPFEM) are usually solved using Newton's method. However, the inherent non-linearity in the flow rule model that characterizes the crystal slip system deformation makes it difficult to form the exact analytical Jacobian needed by Newton's method. Here we analyze how to circumvent this problem by using Jacobian Free Newton Krylov (JFNK), as it does not require a Jacobian. JFNK is used to solve the system of fully coupled implicit non-linear PDEs by using an approximation to the jacobian, in contrast to the traditional Newton solve thus significantly reducing the computational time. Further studies will be aimed at extending this work in simulating the effects of plasticity on 3-D microstructural evolution to characterize performance of nuclear fuels.

These studies are being performed to support in-pile tests of similar fuels and bound the expected behavior in terms of formation of brittle or low-melting point phases due to interdiffusion of fuel constituents into the cladding and cladding constituents into the fuel. The complex phase evolution observed will be discussed in terms of available equilibrium phase diagram data and the relation to anticipated in-pile behavior.

This restructuring in the fuel has a significant impact on thermal conductivity and fission gas release, and therefore is of critical importance when predicting fuel performance. To gain a better understanding of fuel restructuring, we use a combination of atomistic and mesoscale phase field simulations to investigate GB and pore migration and how the two interact. We also compare the effects of stress and temperature gradients. Finally, we demonstrate how this information can be used to improve existing fuel performance materials models.

The HT-UPS alloy, with a composition based largely on modifications to 316 stainless steel (SS), demonstrates improved creep resistance through additions of Ti and Nb that form nano-scale MC precipitates. The cycles to failure at 650 degree C of HT-UPS and 316 SS are similar in fatigue and creep-fatigue despite differences in peak stress profiles and the deformed microstructures. Internal grain boundary damage resulting from the tensile hold is present in the form of fine cracks for longer hold times, and substantially more of these internal cracks are visible in 316 SS than HT-UPS. The cycled dislocation substructure in 316 SS has regions with an equiaxed cellular structure and regions with a lath structure, whereas tangles of dislocations are pinned at the nanoscale MC precipitates in HT-UPS.

To make KMC simulations robust, corresponding molecular dynamics simulations are consulted, which provide the nucleation mechanisms in detail within various settings. In the current work, the He bubble nucleation process at three types (twin, tilt and twist) of GBs is studied with randomly distributed He atoms as the initial condition. It is found that He bubbles nucleate at GBs with different rates and more He bubbles appear at tilt and twist boundaries. This is because the He binding energy of tilt and twist GBs is superior over the counterpart of twin GBs. Furthermore, inhomogeneous nucleation occurs with the impact of dislocations.

Central to the retention and release of fission gases is the evolution of bubbles existing on grain boundaries and grain triple junctions. Here, three-dimensional phase-field simulations of the growth and coalescence of intergranular Xe bubbles in UO2 bicrystal grain geometries will be presented. We investigate the dependency of bubble percolation on three factors: the initial bubble density, the Xe grain boundary diffusivity, and the bubble shape, which is governed by the ratio of the grain boundary energy over the surface energy. The simulations show that variations of each of these factors can lead to large discrepancies in the bubble coalescence rate, and eventual percolation, which may partially explain this observed occurrence in experimental investigations. This research was supported by the NEAMS program within DOE-NE.

Hence, a new monolithic fuel type that possesses the greatest possible uranium density in the fuel region is being developed, where the fuel region consists of a single foil encased inside an aluminum alloy cladding. Currently, efforts are ongoing to evaluate the mechanical properties and microstructure of fresh U-Mo fuels, as a function of molybdenum content, carbon content and temperature. Small-scale specimen testing techniques, such as sub-size tensile testing, microindentation hardness testing and shear punch testing are being performed. Other materials characterization techniques, such as optical microscopy, XRD and SEM are being used in conjunction with the small-scale mechanical test methods.

Irradiation to 653 effective full power days resulted in fuel burnups ranging from approximately 17-30 at.% HM. These alloys (e.g., U-29Pu-4Am-2Np-30Zr) are being studied in order to understand how fuel incorporating constituents from recycled light water reactor fuel would behave in fast reactors, with particular focus on transmuting actinides. Initial destructive postirradiation examinations of these alloys have been completed, including fission gas release, optical microscopy, and burnup analysis. Select results will be presented and compared to results from lower burnup companion experiments and the historical metallic fuel performance database.

Extensive post-irradiation examination of the fuel is currently in progress. A critical component of the fuel characterization is microanalysis of the irradiated fuel particles, including ceramography, scanning electron microscopy, wavelength dispersive spectroscopy, and transmission electron microscopy of coatings and fuel kernels. Among the primary objectives of this examination are to determine the effects of irradiation on coating integrity, correlate coating microstructures with the extent of fission product retention, and develop a better understanding of fission product diffusive release. Of particular interest is silver, which has long been known to exhibit relatively high release from coated particle fuel. This paper will highlight some of the microanalytical techniques being utilized and present preliminary results.

Rare earth fission products produced during irradiation migrate to the fuel-cladding interface where they can depress solidus temperatures leading to breach of cladding. Furthermore, recycled fuel for a fast burner reactor used to destroy actinides may contain several percent rare earth fission products prior to reactor insertion, leading to fuel-cladding chemical interactions at the outset. This paper describes the selection of additives to complex rare earth fission products during both fuel production and irradiation. It also describes the fabrication and characterization of experimental fuels to test these concepts. Preliminary results indicate effective gettering of (surrogate) rare earth fission products in as-fabricated fuel doped with rare earths. In fuels fabricated without rare earths, the getter forms intermetallics with other constituents.

Since surfaces can facilitate more rapid transport than the bulk fuel alloy, it is important to characterize the transport of fuel constituents, fission products, and cladding components in porous fuel bodies. Special-effects, out-of-pile tests were therefore designed and are being implemented to assess the significance of porosity on transport, which may be critical to understanding the fuel behavior and to modeling. We describe methods of preparing porous alloy fuels, which included atomizing the alloys into spherical or flake powders. Powders were subsequently sintered and prepared as diffusion couples with reactive counterparts, such as iron. These experiments are a crucial supplement to the traditional bulk diffusion and transport experiments for understanding and modeling fuel properties. We will summarize the rationale and need, experimental plans, recent developments, and future steps.

The addition of Si to the Al has been considered with positive results. Compositional modification to replace Si with Ge is now under evaluation to further improve irradiation behavior and recycling of spent fuel systems. In this study, the microstructural and phase development of a diffusion couple of U-7 wt.% Mo in contact with Al-7 wt.% Ge was examined by transmission electron microscopy, scanning electron microscopy and energy dispersive spectroscopy. The interdiffusion zone developed a three phase microstructure containing an amorphous phase, the orthorhombic-UGe2 and the cubic-(U,Mo)(Al,Ge)(3) phase. Results from this study are compared to U-Mo vs. pure Al and U-Mo vs. Al-Si diffusion couples to discuss the differences in the microstructural evolution of the different interdiffusion zones.

Capabilities in advanced micro-structural analysis of irradiated as well as un-irradiated reactor structural and pressure boundary materials supplement a full suite of mechanical characterization infrastructure. Recent advancements include acquisition of a Local Electrode Atom Probe (LEAP) and Transmission Electron Microscope (TEM) capable of handling irradiated materials as well as highly shielded mechanical test systems intended for characterization of such parameter as Irradiation Assisted Stress Corrosion Cracking (IASCC) resistance, and Fracture Toughness. The INL is currently involved in developing code cases for advanced, NGNP materials and will soon be involved in characterization of irradiated material properties for the LWR life extension effort. This paper covers current and upcoming nuclear materials research programs based at INL.

In order to provide adequate test data for design Code purposes, numerous strain controlled low-cycle fatigue (LCF) tests with hold times up to 1800 s at peak tensile strain have been conducted at 950 degree C. Post-test observations reveal that bulk grain boundary damage in the form of intergranular cracking was present in the interior of the creep-fatigue specimens. This bulk cracking was observed throughout the deformed material in distinct grain boundary locations, although the majority of grain boundaries were absent of any observable damage or signs of cavitation. Localized strain fields in the grains adjacent to interior cracks are being investigated using orientation imaging microscopy (OIM) techniques coupled with transmission electron microscopy (TEM) characterization.

The percolation of gas bubbles on grain boundaries, and the subsequent percolation of grain boundary networks is the primary mechanism of fission gas release from nuclear fuels. Both radial cracks and radial gradients in grain boundary property distributions are correlated with the fraction of grain boundaries vented to the free surfaces. Our results show that cracks surprisingly do not significantly increase the percolation of uniform grain boundary networks. However, for networks with radial gradients in boundary properties, the cracks can considerably raise the vented grain boundary content.

Such an approach will require injecting chemical amendments into the subsurface to generate supersaturated conditions that promote mineral precipitation. However, the formation of reactant mixing zones will create gradients in both the saturation state and ion activity ratios (i.e., aCO3 2? /aCa2+). To better understand the effect of ion activity ratios on CaCO3 precipitation kinetics and Sr2+ co-precipitation, experiments were conducted under constant composition conditions where the supersaturation state (?) for calcite was held constant at 9.4, but the ion activity ratio (r = aCO3 2? /aCa2+ ) was varied between 0.0032 and 4.15. : Calcite was the only phase observed, by XRD, at the end of the experiments. Precipitation rates increased from 41.3 + or - 3.4 ?mol m-2 min-1 at r = 0.0315 to a maximum rate of 74.5 + or - 4.8 ?mol m-2 min-1 at r = 0.306 followed by a decrease to 46.3 + or - 9.6 ?mol m-2 min-1 at r = 1.822. The trend was simulated using a simple mass transfer model for solute uptake at the calcite surface. However, precipitation rates at fixed saturation states also evolved with time. Precipitation rates accelerated for low r values but slowed for high r values. These trends may be related to changes in effective reactive surface area. The aCO3 2? /aCa2+ ratios did not affect the distribution coefficient for Sr in calcite (DP Sr 2+), apart from the indirect effect associated with the established positive correlation between DP Sr 2+ and calcite precipitation rate. At a constant supersaturation state (? = 9.4), varying the ion activity ratio affects the calcite precipitation rate. This behavior is not predicted by affinity-based rate models. Furthermore, at the highest ion ratio tested, no precipitation was observed, while at the lowest ion ratio precipitation occurred immediately and valid rate measurements could not be made. The maximum measured precipitation rate was 2-fold greater than the minima, and occurred at a carbonate to calcium ion activity ratio of 0.306. These findings have implications for predicting the progress and cost of remediation operations involving enhanced calcite precipitation where mineral precipitation rates, and the spatial/temporal distribution of those rates, can have significant impacts on the mobility of contaminants.

Facility modeling that can integrate and interpret observations collected from monitored facilities in order to ascertain their functional details will be a critical element of these methods. Although improvements are continually sought, existing facility modeling tools can characterize all aspects of reactor operations and the majority of nuclear fuel cycle processing steps, and include algorithms for data processing and interpretation. Assessing nonproliferation status is challenging because observations can come from many sources, including local and remote sensors that monitor facility operations, as well as open sources that provide specific business information about the monitored facilities, and can be of many different types. Although many current facility models are capable of analyzing large amounts of information, they have not been integrated in an analyst-friendly manner. This paper addresses some of these facility modeling capabilities and illustrates how they could be integrated and utilized for nonproliferation analysis. The inverse problem of inferring facility conditions based on collected observations is described, along with a proposed architecture and computer framework for utilizing facility modeling tools. After considering a representative sampling of key facility modeling capabilities, the proposed integration framework is illustrated with several examples.

Vehicle fuel is the only current energy use large enough to absorb all the energy capacity that might be diverted from the power industry, and its ease of storage obviates problems with discontinuous synfuel production. The potential benefits and challenges of synfuels integration are illustrated by the production of methanol from natural gas (as a source of carbon) using steam from a light water nuclear power reactor which is assumed to be available in accord with a year's worth of power demand data. The synthesis of methanol is easily adapted to using 300 degree C heat from a light water reactor and this simple compound can be further processed into gasoline, biodiesel (to esterify vegetable oils), or dimethyl ether, fuels which can be used with the current vehicle fleet. A supplemental feed to the methanol process of natural gas (for energy) allows operation at constant full rate when the nuclear heat is being used to produce electrical power. The higher capital costs of such a system are offset by a lower cost of heat and power production from a large base load type of plant and by reduced costs associated with much lower CO sub(2) emissions. Other less tangible economic benefits of this and similar hybrid systems include better use of natural resources for fuels and greater energy supply reliability from the domestic production of vehicle fuel.

One such example of a mafic rock CO (sub 2) analog is the Soda Springs site located in Caribou County of southeastern Idaho, USA. At this site, CO (sub 2) and formation fluids generated by the dissolution of Paleozoic carbonates at depth are migrating and reacting with a series of shallower thoelitic basalt flows that host a fresh water aquifer. We believe that the layered basalt flows are acting as a reactive barrier to the vertical migration of the deep CO (sub 2) charged fluids. However, in several cases the CO (sub 2) charged reservoir fluids make it to the surface and are expressed as either carbonated springs, or as a cold-water geyser that was caused by wells that encounter the system at depth. Analysis of these sources of water shows a steady evolution of groundwater from unaffected by the basalt (deep wells) to more fully reacted (springs). Data from this system makes a compelling argument for the ability of basalt flow to maintain containment for CCS applications. Our study has shown that CO (sub 2) charged fluids migrating upwards are being neutralized by mineral dissolution and precipitation within the basalt flows. These neutralization reactions have resulted in a specific chemical signature being imparted to the formation fluid that can be used to determine which minerals are dissolving and precipitating. Through and integrated study of this natural analog site including field and laboratory experiments, the relative roles of mineral dissolution and precipitation and phase assemblage are being characterized for this basalt-hosted system. The benefit of studying this natural analog is that it has been active for many 1000's of years and depending on sample location and depth, the resulting fluid chemistry carries the chemical signature (tracer) indicative of the degree of reaction within the basalt formation. Additionally, the study of this system is helping define the appropriate laboratory scale experiments that will be needed to accomplish the larger objective of the project, understanding changes in aqueous geochemistry associated with progressing CO (sub 2) -water-interactions.

To ensure high confidence in and efficient use of this state-of-the-art facility, it is important to maintain high standards of verification and validation. INL is in the processes of updating its nuclear software and design practices for the ATR to be consistent with modern verification and validation standards. This update project is replacing over-conservatism with modern "best-estimate" nuclear codes and models. Here "best-estimate" is meant to mean that the approach applies the state-of-the-art, best available (hence, best-estimate) tools and codes to compute safety margins in the ATR. Furthermore, it is essential to thoroughly test the code and model to know its accuracy (i.e., uncertainty due to covariance relationships with input data) and its precision (i.e., the systematic biases not associated with input data uncertainty).

An irradiated U sub(3)Si sub(2)/Al dispersion fuel ( super(235)U [approx] 75%) from the high-flux side of a fuel plate (U0R040) from the Reduced Enrichment for Research and Test Reactors (RERTR)-8 test was characterized using transmission electron microscopy (TEM). The fuel was irradiated in the Advanced Test Reactor (ATR) for 105 days. The average irradiation temperature and fission density of the U sub(3)Si sub(2) fuel particles for the TEM sample are estimated to be approximately 110 degree C and 5.4 x 10 super(27) f/m super(3). The characterization was performed using a 200-kV TEM. The U/Si ratio for the fuel particle and (Si + Al)/U for the fuel-matrix-interaction layer are approximately 1.1 and 4-10, respectively. The estimated average diameter, number density and volume fraction for small bubbles (1 mu m) in the fuel particle are [approx]94 nm, 1.05 x 10 super(20) m super(-3) and [approx]11%, respectively. The results and their implication on the performance of the U sub(3)Si sub(2)/Al silicide dispersion fuel are discussed.

The effectiveness of sequestration depends on the storage capacity and stability of the reservoir and risk of leakage into the overburden. Reservoir rocks can react with a CO (sub 2) -water mixture, potentially resulting in the precipitation of minerals in the available matrix pore space and within pre-existing fractures. This induced mineralization may form internal seals that could help mitigate the leakage of CO (sub 2) into the overburden. For basaltic host rocks, carbonic acid partially dissolves minerals in the host rock, such as the calcium plagioclase mineral, freeing various cations (e.g., Ca (super 2) + and Mg (super 2) +) for later precipitation as carbonate cements (Gislason et al., 2010).

Venus is often termed Earth's sister planet, yet they have evolved in strikingly different ways. Venus' surface and atmosphere dynamics, and their complex interaction are poorly constrained. A lander mission to Venus would enable us to address a multitude of outstanding questions regarding the geological evolution of the Venusian atmosphere and crust. Our proposed mission concept, VenUs Lander for Composition ANalysis (VULCAN), is a two-component mission, consisting of a lander and a carrier spacecraft functioning as relay to transmit data to Earth. The total mission duration is 150 days, with primary science obtained during a 1-hour descent through the atmosphere and a 2-hour residence on the Venusian surface. In the atmosphere, the lander will provide new data on atmospheric evolution by measuring dominant and trace gas abundances, light stable isotopes, and noble gas isotopes with a neutral mass spectrometer. It will make important meteorological observations of mid-lower atmospheric dynamics with pressure and temperature sensors and obtain unprecedented, detailed imagery of surface geomorphology and properties with a descent Near-IR/VIS camera. A nepholometer will provide new constraints on the sizes of suspended particulate matter within the lower atmosphere. On the surface, the lander will quantitatively investigate the chemical and mineralogical evolution of the Venusian crust with a LIBS-Raman spectrometer. Planetary differentiation processes recorded in heavy elements will be evaluated using a gamma-ray spectrometer. The lander will also provide the first stereo images for evaluating the geomorphologic/volcanic evolution of the Venusian surface, as well as panoramic views of the sample site using multiple filters, and detailed images of unconsolidated material and rock textures from a microscopic imager. Our mission proposal will enable the construction of a unique Venus test facility that will attract a new generation of scientists to Venus science. With emphasis on flight heritage, we demonstrate our cost basis and risk mitigation strategies to ensure that the VULCAN mission can be conducted within the requirements and constraints of the New Frontiers Program.

The blocks represent portions of the lithosphere that are separated by faults and extend from the surface to a depth where the faults become stress-rate free. Each block is thought of as a small tectonic plate that can rotate on the Earth's surface and may also be subject to elastic strain rates from friction on its bounding faults or anelastic strain rates from internal faults or both. In most block model implementations, the motions are described kinematically, that is, there are no forces involved and hence they do not describe plate dynamics. Nevertheless, block modeling serves useful purposes such as accounting and correcting for the elastic strain rates that can be very large near faults, providing direct estimates of the slip rates on faults, and providing kinematic information that indirectly constrain dynamical models (strain and spin rates for examples). Limitations on the size of blocks that can be used arise from both data and mechanical reasons. Because the elastic strain around faults can be several tens of kilometers in wavelength, geodetic data have difficulty resolving the relative motions of blocks at this scale. Additional independent data, such as fault slip rates estimated from geology, that are not subject to the elastic strain, can help to constrain the motion of small blocks. From a mechanical point of view, small blocks may be better described as part of a continuum as might be expected for continental deformation. We will describe recent GPS results from the western US in which we observe regions of low strain rates within broadly deforming belts. The regions vary in size from irresolvably small to large fractions of the western US deforming region.

The 1983 Borah Peak earthquake (M=7.3) generated a 36 km long range-front fault scarp characterized by more than 2 m of normal slip and minor left lateral movement. Profiles can be used to measure individual scarp height and slope as well as cumulative throw where multiple scarps formed. The morphology, geometry, and surface roughness of the scarps are compared across the length of the dataset, demonstrating differences in the materials controlling the scarp profiles. Variations in scarp degradation during the past 25+ years may also be evident. The scarp profiles measured by the terrestrial and airborne datasets are compared for differences in accuracy between the two laser altimetry methods. The fused terrestrial and airborne point cloud datasets are used to extrapolate the higher resolution metrics from the terrestrial data to the coarser-resolution but larger geographic extent of the airborne data.

To address this need, ASME (American Society of Mechanical Engineers) Standards and Certification has established the V&V 30 Committee, under the jurisdiction of the V&V Standards Committee, to develop a consensus standard for verification and validation of software used for design and analysis of advanced reactor systems. The initial focus of this committee will be on the V&V of system analysis and computational fluid dynamics (CFD) software for nuclear applications. To limit the scope of the effort, the committee will further limit its focus to software to be used in the licensing of High-Temperature Gas-Cooled Reactors. Although software verification will be an important and necessary part of the standard, much of the initial effort of the committee will be focused on the validation of existing software and new models that could be used in the licensing process. In this framework, the Standard should conform to Nuclear Regulatory Commission (NRC) and other regulatory practices, procedures and methods for licensing of nuclear power plants as embodied in the United States (U.S.) Code of Federal Regulations and other pertinent documents such as Regulatory Guide 1.203, "Transient and Accident Analysis Methods" and NUREG-0800, "NRC Standard Review Plan". In addition, the Standard should be consistent with applicable sections of ASME NQA-1-2008 "Quality Assurance Requirements for Nuclear Facility Applications (QA)". This paper describes the general requirements for the proposed V&V 30 Standard, which includes: (a) applicable NRC and other regulatory requirements for defining the operational and accident domain of a nuclear system that must be considered if the system is to be licensed, (b) the corresponding calculation domain of the software that should encompass the nuclear operational and accident domain to be used to study the system behavior for licensing purposes, (c) the definition of the scaled experimental data set required to provide the basis for validating the software, (d) the ensemble of experimental data sets required to populate the validation matrix for the software in question, and (e) the practices and procedures to be used when applying a validation standard. Although this initial effort will focus on software for licensing of High-Temperature Gas-Cooled Reactors, it is anticipated that the practices and procedures developed for this Standard can eventually be extended to other nuclear and non-nuclear applications.

The mid ocean ridge basalt that comprises the basement rocks of the plate offers many attractive characteristics for carbon dioxide disposal, including a thick cover of low-permeability sediments, access to potentially a large storage volume with good injectivity, proximity to population centers, and the potential for gravity trapping of free-phase carbon dioxide due to the temperature/pressure regime. However, investigations of the suitability of the Juan de Fuca plate for carbon injection to date have been largely conceptual in nature. Here we present a hypothetical, although rigorous and quantitative, numerical analysis of some potential sequestration scenarios in an area of the Juan de Fuca bounded between approximately 47.8776 and 47.9864 degrees (decimal latitude) and -127.448/-127.338 degrees (decimal longitude). We use data garnered from ODP seismic records and drilling logs to develop a numerical model that captures some essential aspects of the study area, including a simplified basalt/sediment geometry and property sets, and simulate the injection of carbon dioxide into the crystalline bedrock. Here we examine the impact of the model geometry and variations in rock property distributions on carbon dioxide storage capacity.

One promising stabilization mechanism for divalent trace ions, such as the short-lived radionuclide (super 90) Sr, is co-precipitation in calcite. We have found that calcite precipitation and co-precipitation of Sr can be accelerated by the activity of urea hydrolyzing microorganisms, that higher calcite precipitation rates can result in increased Sr partitioning, and that nutrient additions can stimulate ureolytic activity. To extend our understanding of microbially induced calcite precipitation (MICP) in an aquifer setting a continuous recirculation field experiment evaluating MICP was conducted at the Integrated Field Research Challenge (IFRC) site located at Rifle, CO. In this experiment, groundwater extracted from an onsite well was amended with urea (total mass of 42.5 kg) and molasses (a carbon and electron donor) and re-injected into a well approximately 4 meters up-gradient for a period of 12 days followed by 10 months of groundwater sampling and monitoring. Crosshole radar and electrical tomographic data were collected prior, during, and after the MICP treatment. The urea and molasses treatment resulted in an enhanced population of sediment associated urea hydrolyzing organisms as evidenced by increases in the number of ureC gene copies, increases in (super 14) C urea hydrolysis rates, and long-term observations of ammonium (a urea hydrolysis product) in the injection, extraction and down gradient monitoring wells. Permeability changes and increases in the calcite saturation indexes in the well field suggest that mineral precipitation has occurred; ongoing analysis of field samples seeks to confirm this. Changes in dielectric constant and electrical conductivity were used to interpret the spatiotemporal distribution of the injectate and subsequent calcite precipitation. Modeling activities are underway to define field-scale urea hydrolysis rates.

The VHTR is a single-phase helium-cooled reactor that will provide helium at up to 1000 degree C. The prospect of a coolant at these temperatures circulating in the reactor vessel demands that careful analysis be performed to ensure that excessively hot spots are not created and that sufficient mixing of the coolant is obtained. Computational fluid dynamics (CFD) coupled with heat transfer will be used to perform the desired analyses. However, primarily because of the imperfect nature of modeling turbulent flow, any CFD calculations used to perform nuclear reactor safety analysis must be validated against experimental data. Experimental data have been taken in a scaled section of the lower plenum of a prismatic VHTR at the matched index of refraction (MIR) facility at the Idaho National Laboratory. These data were taken with the intent that they be examined for use as validation data. A series of investigations have been conducted to assess the MIR data. Issues that have already been examined include the extent of the required computational domain, the outlet boundary condition, the inlet data and the effect of the turbulence model. One of the jets that flow into the model impacts on a wedge, which represents a portion of a hexagonal graphite block that lines the inner wall of the lower plenum. The nature of the flow below this particular jet is such that a randomly varying recirculation zone is created. This recirculation zone is seen to change in size, causing a relatively long-time scale of motion or disturbance of the flow in the model. It is concluded that such a feature is undesirable in a validation data set, firstly because of its apparent random nature and, secondly, because to obtain an appropriate long-time average would be impractical because of the compute time required. It is predicted computationally that by eliminating the first of the four inlet jets into the scaled model, the resulting recirculation zone is rendered stable.

A central component of the HYTEST is the slurry bubble column reactor (SBCR) in which the gas-to-liquid reactions are performed to synthesize transportation fuels using the Fischer Tropsch (FT) process. These SBCRs operate in the churn-turbulent flow regime, which is characterized by complex hydrodynamics, coupled with reacting flow chemistry and heat transfer. Results, our team is developing a research tool to aid in understanding the physicochemical processes occurring in the SBCR. A robust methodology to couple reaction kinetics and mass transfer into a four-field model (consisting of the bulk liquid, small bubbles, large bubbles and solid catalyst particles) consisting of thirteen species, which are CO reactant, H sub(2 reactant, hydrocarbon product, and H) sub(2)O product in small bubbles, large bubbles, and the bulk fluid plus catalyst is outlined. Mechanistic submodels for interfacial momentum transfer in the churn-turbulent flow regime are incorporated, along with bubble breakup/coalescence and two-phase turbulence submodels. The absorption and kinetic models, specifically changes in species concentrations, have been incorporated into the mass continuity equation. The reaction rate is based on the macrokinetic model for a cobalt catalyst developed by Yates and Satterfield. The model includes heat generation produced by the exothermic chemical reaction, as well as heat removal from a constant temperature heat exchanger. A property method approach is employed to incorporate vapor-liquid equilibrium (VLE) in a robust manner. Physical and thermodynamic properties as functions of changes in both pressure and temperature are obtained from VLE calculations performed external to the computational multiphase fluid dynamics (CMFD) solver. The novelty of this approach is in its simplicity, as well as its accuracy over a specified temperature and pressure range.

However, aeolian deposits usually exhibit inherent internal complexities induced by migrating bedforms of different sizes and their resulting bounding surfaces. Therefore, CO2 plume migration in such complex media should be well defined and successively linked in models for better characterization of the plume behavior. Based on an outcrop analog of the upper Navajo Sandstone in the western flank of the San Rafael Swell, Utah, we identified five different bedform types with dune and interdune facies to represent the spatial continuity of lithofacies units. Using generated 3D geometrical facies patterns of cross-bedded structures in the Navajo Sandstone, we performed numerical simulations to understand the detailed behavior of CO2 plume migration under the different cross-bedded bedforms. Our numerical simulation results indicate that cross-bedded structures (bedform types) play an important role on governing the rate and directionality of CO2 migration, resulting in changes of imbibition processes of CO2. CO2 migration tends to follow wind ripple laminations and reactivation surfaces updip. Our results suggest that geologically-based upscaling of CO2 migration is crucial in cross-bedded formations as part of reservoir or basin scale models. Furthermore, comparative modeling studies between 3D models and 2D cross-sections extracted from 3D models showed the significant three-dimensional interplay in a cross-bedded structure and the need to correctly capture the geologic heterogeneity to predict realistic CO2 plume behavior. Our outcrop analog approach presented in this study also demonstrates an alternative method for assessing geologic CO2 storage in deep formations when scarce data is available.

At the Idaho National Laboratory (INL), (super 90) Sr has been detected in perched water bodies underlying the Idaho Nuclear Technology and Engineering Center (INTEC) facility. Microbially induced calcite precipitation (MICP) using urea-hydrolyzing microbes is one proposed approach for immobilization of (super 90) Sr in the subsurface. The sequestration mechanism is co-precipitation in calcite, promoted by the production of carbonate alkalinity from ureolysis. In order to assess the potential efficacy of MICP at INTEC a field study was conducted at the INL Vadose Zone Research Park (VZRP). The VZRP is located approximately 3 km from INTEC and shares many of the same hydrologic and lithologic features but in a non-contaminated setting. We conducted experiments over two field seasons in a perched water body located approximately 15 meters below land surface, using a 5-spot wellfield design. During the first season amendments (molasses and urea) were injected into the central well and water was extracted from two wells on either side, located along a diagonal. Water samples were characterized for microbial abundance, ureolytic activity and ureC gene numbers, along with solution composition. Before, during and after the injections cross-borehole geophysical imaging was performed, using various combinations of the available wells. During the second field season in situ static experiments were conducted to specifically characterize attached and unattached microbial communities, using surrogate substrates colonized during a 12 week incubation. Based on the field data a first order in situ urea hydrolysis rate constant of 0.034 d (super -1) was estimated. This was more than an order of magnitude higher than rate constants estimated above-ground using water samples, suggesting that attached microorganisms were responsible for >90% of the observed urea hydrolysis activity. The geophysical monitoring data indicated that both radar and electrical resistivity techniques were able to sense the spatiotemporal distributions of the amendments. In the static incubation studies, the activity of the attached community was >1000x higher than the unattached community. Phospholipid biomass estimates for the attached community using two different matrices were 1,000x and 10,000x higher than for the unattached. Community structure changes were seen over time and between wells. Streamtube ensemble-based modelling was applied to simulate the combined well-to-well transport and reaction system processes, with several simplifying assumptions including an immobile biomass phase. The transport model was calibrated by fitting the traveltime distribution function to bromide tracer data, and provided a useful framework for simulation of the reactive transport as indicated by the arrival of urea at the withdrawal well.

For reactive transport systems that are large, highly nonlinear, and tightly coupled due to complex reactions and strong solution-mineral interactions, a preconditioned Jacobian-free Newton-Krylov (JFNK) solution approach is applied to solve the PDAEs in a fully coupled, fully implicit manner. The advantage of the JFNK method is that it avoids explicit computation and storage of the Jacobian matrix during Newton nonlinear iterations, which is highly desirable for efficient solution of large reactive transport problems. This approach is also enhanced by a physics-based blocking approach for constructing the preconditioner and multigrid algorithm for efficient inversion of preconditioners. The preconditioning strategy can account for both inter-cell transport-reaction self-coupling by using the diagonal blocks of the approximate Jacobian and the additional intra-cell transport-reaction cross-coupling through off-diagonal blocks at minimal additional computational cost. Numerical results are presented to demonstrate the efficiency and massive scalability of the solution strategy for reactive transport problems involving strong solution-mineral interactions and fast kinetics. This approach has been applied to two reactive transport systems involving induced mineral precipitation. In the first system, calcite precipitation takes place as a result of the combination of injected calcium and ureolysis-produced bicarbonate ions. In the other system, separate solutions containing calcium and bicarbonate ions are introduced into the porous medium in a parallel injection format such that calcium carbonate mineral precipitates in the mixing zone formed between the two fluids. Highly nonlinear coupling effects of fluid flow, transport, kinetic and equilibrium reactions, and changes in media properties are investigated by using the preconditioned JFNK solution approach for both systems. The numerical simulation results are compared to laboratory experiment results, and the comparison demonstrates that the fully-coupled, fully-implicit solutions can capture the transient events and sharp chemical gradients characteristic of the system, including the changes in flow properties caused by mineral precipitation and/or dissolution.

For example, magnitudes predicted for the Wasatch (Utah), Lost River (Idaho), and Lemhi (Idaho) Faults from fault segment lengths, Lseg, where lengths are defined between geometrical, structural, and/or behavioral discontinuities assumed to persistently arrest rupture, are consistently less than magnitudes calculated from displacements, D, along these same segments. For self-similarity, empirical relationships (e.g. Wells and Coppersmith, 1994) should predict consistent magnitudes (M) using diverse fault dimension values for a given fault (i.e. M approximately Lseg, should equal M approximately D). Typically, the empirical relationships are derived from historical earthquake data and parameter values used as input into these relationships are determined from field investigations of paleoearthquakes. A commonly used assumption--grounded in the characteristic-earthquake model of Schwartz and Coppersmith (1984)--is equating Lseg with surface rupture length, SRL. Many large historical events yielded secondary and/or sympathetic faulting (e.g. 1983 Borah Peak, Idaho earthquake) which are included in the measurement of SRL and used to derive empirical relationships. Therefore, calculating magnitude from the M approximately SRL relationship using Lseg as SRL leads to an underestimation of magnitude and the M approximately Lseg and M approximately D discrepancy. Here, we propose an alternative approach to earthquake magnitude estimation involving a relationship between moment magnitude, Mw, and length, where length is Lseg instead of SRL. We analyze seven historical, surface-rupturing, strike-slip and normal faulting earthquakes for which segmentation of the causative fault and displacement data are available and whose rupture included at least one entire fault segment, but not two or more. The preliminary Mw approximately Lseg results are strikingly consistent with Mw approximately D calculations using paleoearthquake data for the Wasatch, Lost River, and Lemhi Faults, demonstrating self-similarity and implying that the Mw approximately Lseg relationship should supplant M approximately SRL relationships currently employed in seismic hazard analyses. The relationship will permit reliable use of Lseg data from field investigations and proper use and weighting of multiple-segment-rupture scenarios in seismic hazard analyses, and eliminate the need to reconcile the Mw approximately SRL and Mw approximately D differences in a multiple-parameter relationship for segmented faults.

Mammoth Mountain is a dormant volcano located in California, where volcanogenic CO (sub 2) is emitted diffusely through soils within relatively large (km (super 2) -scale) areas. We used the eddy covariance (EC) and accumulation chamber (AC) techniques at the Horseshoe Lake tree-kill area on Mammoth Mountain to map the spatial distribution of diffuse CO (sub 2) fluxes and quantify CO (sub 2) emission rate. EC measurements of CO (sub 2) flux during September-October 2010 ranged from 85 to 1766 g m (super -2) d (super -1) . Three AC soil CO (sub 2) flux surveys during this time were used to simulate maps of soil CO (sub 2) flux and estimate total emission rates. A least-squares inversion of measured EC CO (sub 2) fluxes and corresponding modeled source weight functions was carried out and recovered 58 to 77% of the CO (sub 2) emission rates estimated based on simulated AC soil CO (sub 2) fluxes. Spatial distributions of modeled surface CO (sub 2) fluxes based on EC and AC observations showed moderate to good correspondence (R (super 2) = 0.36 to 0.70). In Soda Springs, Idaho, CO (sub 2) of deep sedimentary origin is released at the surface from a number of relatively small-area carbonated spring sources. In Fall 2011, we will use for the first time the eddy covariance method in conjunction with aqueous geochemistry to map and quantify CO (sub 2) emissions from a high discharge spring and surrounding marsh area. Our results from Mammoth Mountain and Soda Springs should provide a framework for integrated monitoring of a range of surface CO (sub 2) leakage styles and geometries.

Basalts are promising host rocks due to their volumetric extend, worldwide distribution, and recent observations that CO (sub 2) -water mixtures react with basalt minerals to precipitate as carbonate minerals, trapping the CO (sub 2) . The chemical reaction between carbonic acid and minerals rich in calcium, magnesium and iron precipitates carbonates in the pore space. This process would increase the elastic modulus and velocity of the rock. At the same time, the higher compressibility of CO (sub 2) over water changes the elastic properties of the rock, decreasing the saturated rock bulk modulus and the P-wave velocity. Reservoirs where the rock properties change as a result of fluid or pressure changes are commonly monitored with seismic methods. Here we present experiments to study the feasibility of monitoring CO (sub 2) migration in a reservoir and CO (sub 2) -rock reactions for a sequestration scenario in basalts. Our goal is to measure the rock's elastic response to mineralization with non-contacting ultrasonic lasers, and the effect of fluid substitution at reservoir conditions at seismic and ultrasonic frequencies. For the fluid substitution experiment we observe changes in the P- and S-wave velocities when saturating the sample with super-critical (sc) CO (sub 2) , CO (sub 2) -water mixtures and water alone for different pore and confining pressures. The bulk modulus of the rock is significantly dependent on frequency in the 2 approximately to 10 (super 6) approximately Hz range, for CO (sub 2) -water mixtures and pure water saturations. Dry and pure CO (sub 2) (sc or gas) do not show a frequency dependence on the modulus. Moreover, the shear wave modulus is not dispersive for either fluid. The frequency dependence of the elastic parameters is related to the attenuation (1/Q) of the rock. We will show the correlation between frequency dependent moduli and attenuation data for the different elastic moduli of the rocks. Three other basalt samples were stored in a pressure chamber with a sc CO (sub 2) -water solution to study the effect of mineralization on the elastic properties of the rock. The rock elastic properties are recorded with non-contacting ultrasonic lasers at room conditions. After 15 weeks the first post-mineralization scan showed differences in the rock velocities with respect to the pre-mineralization scan. The analysis is done through coda wave interferometry and direct arrivals. The samples were inserted back into the pressure vessel for continuing mineralization and subsequent scans. Finally, we will discuss the applicability of Gassmann's equation and how the combination of mineralization together with CO (sub 2) -water mixture affects the velocity of waves in basalt rocks.

Conventionally, in order to reduce computational cost, these types of problems are solved using operator splitting method, usually by sequentially coupling a subsurface flow and heat transport simulator with a solid mechanics simulator via input files. However, such operator splitting approaches are applicable only to loosely coupled problems and usually converge slowly. As in most enhanced geothermal systems (EGS), fluid flow, heat transport, and rock deformation are typically strongly nonlinearly coupled, an alternative is to solve the system of nonlinear partial differential equations that govern the system simultaneously using a fully coupled solution procedure for fluid flow, heat transport, and solid mechanics. This procedure solves for all solution variables (fluid pressure, temperature and rock displacement fields) simultaneously, which leads to one large nonlinear algebraic system that needs to be solved by a strongly convergent nonlinear solver. Development over the past 10 years in the area of physics-based conditioning, strongly convergent nonlinear solvers (such as Jacobian Free Newton methods) and efficient linear solvers (such as GMRES, AMG), makes such an approach competitive. In this presentation, we will introduce a continuum-scaled parallel physics-based, fully coupled, modeling tool for predicting the dynamics of fracture initiation and propagation, fluid flow, rock deformation, and heat transport in a single integrated code named FALCON (Fracturing And Liquid-steam CONvection). FALCON is built upon a parallel computing framework developed at Idaho National Laboratory (INL) for solving coupled systems of nonlinear equations with finite element method with unstructured and adaptively refined/coarsened grids. Currently, FALCON contains poro- and thermal-elastic models, and employs two rock deformation criteria: Mohr-Coulomb and tensile failure to describe the hydro-fracturing processes, while the fluid properties (such as density, viscosity) are evaluated with most recent water/steam equations of state to compute pressure and temperature fields with higher accuracy. Simulation results from FALCON of a hydrofracing process in an idealized EGS system, an EGS cooling process in a fracture network and a combined thermal/hydrological fracturing process will be demonstrated.

In addition, an EGS with supercritical CO2 as a working fluid may also act as a mechanism for CO2 sequestration. To explore this, one must understand the various interactions that may take place between the reservoir rock and the supercritical CO2. In this work, we perform simulations in two and three dimensions using the massively parallel flow and transport code PFLOTRAN, to study these interactions under various conditions (aqueous, non-aqueous and two-phase). The two dimensional results using PFLOTRAN are compared with simulations made using the TOUGH2 code. Numerical studies examining mineral dissolution and precipitation reactions that may occur in EGS that use supercritical CO2 are also shown, in addition to preliminary indications of which well placements may enable optimal flow rates and simultaneous CO2 sequestration.

Chemical gradients within mixing zones will determine the rates and products of reactions, which in turn can modify the permeability and flow paths within the porous media. This reaction-transport coupling is being studied using double diffusion experiments and reactive transport modeling, with calcium carbonate and calcium phosphate as the model mineral systems. In particular we are investigating: (1) the interplay between permeability modifications and reactions that can change local chemical conditions, hydrodynamic conditions, and therefore the rate of precipitation, (2) narrowing ("focusing") of the precipitation zone, and (3) migration of the precipitation zone associated with asymmetry across the mixing zone with respect to precipitation rates and/or local chemical conditions. Experiments are being conducted in hydrogel (polyacrylamide) and granular (glass beads and fine-grained sand) media. Gels were used to investigate the role of diffusion alone on the structure of precipitation zones. We observed differences between carbonate and phosphate systems with respect to the induction period for precipitation, and the position and migration of the precipitation zone. One interesting observation was that multiple precipitation bands are produced in the calcium phosphate system, while no clear banding has been observed in the calcium carbonate system. Initial reactive transport simulations that couple precipitation kinetics with reactant transport and mixing appear consistent with the experimental observations. Precipitation band width and position were found to change with time, and precipitation appeared to slow subsequent reactions at the mixing interfaces. The induction time, spacing between the precipitation bands and band width in the calcium phosphate system were influenced by pH, saturation state and relative concentration of components in the reservoirs. Diffusion of dye added before and after precipitation of minerals in both model systems help to visualize the reduction in permeability (but not complete clogging) of the porous media. In experiments using granular media, pressure or density driven transport can occur, increasing the complexity of chemical gradient dynamics in the mixing zone. Precipitation reactions themselves can reduce local solution density. As a result, the position of the precipitation zone can be less stable and more mobile than in diffusion-dominated systems (e.g., gels). Such observations will have implications for solute transport in engineered precipitation strategies for subsurface systems and for interpretation of field-scale data for reaction kinetics that relies on volume averaging of chemical conditions.

While fluvially-eroded ranges tend to be exhumed more on the windward side, glacially-eroded ranges can experience greater erosion on the leeward side. On the timescale of an individual glaciation, the distribution of precipitation and settling is a key component of glacier mass balance and ice extent, while on longer timescales, the interaction of precipitation and topography can play a major role in landscape evolution and range morphology. Numerical modelling of last glacial maximum (LGM) ice extents for catchments on the eastern side of the Southern Alps, New Zealand, highlights the importance of the distribution of precipitation. The accumulation areas of the glaciers would have experienced much greater precipitation than lower elevations, because of the pronounced orographic precipitation gradient, so glacier length is very sensitive to the precipitation distribution employed for any given temperature change. This is particularly challenging given the lack of modern snow monitoring at high altitudes within the Southern Alps, the likelihood of steep accumulation gradients amongst high topography, below the resolution of current datasets, and the difficulty of extrapolating modern values to the LGM. The Sangre de Cristo Range, southern Colorado, and the Bitterroot Range on the Idaho-Montana border both run close to north-south, cross-cutting the prevailing westerly winds. Drainage basins on both sides of the ranges cover similar areas, but moraines are much more substantial on the eastern sides, indicating greater glacial incision, which we suggest at least partly reflects snow blown over the range crest. The Uinta Mountains, Utah, run west-east, parallel to prevailing winds, and show topographic asymmetry across individual catchments, rather than at the range scale. Rapid rock uplift and significant glacial erosion of the north-south Teton Range, Wyoming, has created some of the highest relief in the conterminous US. While an initial topographic asymmetry would have arisen from the tectonic gradient imposed by the extensional Teton Fault on the east side of the range, the topographic asymmetry would have been exaggerated by feedbacks associated with glacial erosion. Slowly-falling snow would have been advected further into the range by prevailing westerlies, which would also have redistributed fallen snow from the subdued topography typical of the headwaters of west-draining basins. Greater topographic shading and cover by rock debris would have mitigated ablation of eastern glaciers bounded by high valley walls. Glacier size, ice flux and erosion would therefore have been enhanced in eastern-draining basins, though only the largest glaciers were capable of eroding at rates that kept pace with rock uplift. Preliminary numerical modelling results are consistent with these inferences of the importance of orographic precipitation and wind-blown snow based on topographic analysis.

These reactor designs are fueled with submillimeter-sized kernels formed into tristructural-isotropic (TRISO) particles that are imbedded in a graphite matrix. The best spatial and temporal representation of the feedback effect is obtained from an accurate approximation of the fuel temperature. Micro-scale models of TRISO particles are necessary in order to obtain accurate predictions during fast transients or when parameters internal to the TRISO are needed. Most accident scenarios in HTRs are characterized by large time constants and slow changes in the fuel and moderator temperature fields. In these situations, a meso-scale, or pebble- and compact-scale, solution provides a good approximation of the fuel temperature as the fission thermal energy transports out of the kernel and into the surrounding matrix with a much shorter time constant. Therefore, in most cases, the matrix can be assumed to be in quasi-static equilibrium with the kernels. These models, however, fail to provide accurate information on the state of the various components of the TRISO during the early stages of transients. Since the coated particles constitute one of the fundamental design barriers for the release of fission products, it becomes important to understand the transient behavior inside this containment system. An explicit TRISO fuel temperature model named THETRIS has been developed and incorporated into the CYNOD-THERMIX-KONVEK suite of coupled codes. The code includes gas-release models that provide a simple predictive capability of the internal pressure during transients. The new model yields similar results to those obtained with other micro-scale fuel models of TRISO particles, but with the added capability to analyze gas release, internal pressure buildup, and effects of a gap in the TRISO. Analysis of bounding benchmark transients yield good agreement with other codes in which the TRISO particles are modeled explicitly. In addition, a sensitivity study of the potential effects on the transient behavior of high-temperature reactors due to the presence of an inter-layer gap is included. Although the formation of a gap occurs under special conditions, its consequences on the dynamic behavior of the reactor can yield responses during fast transients that depart significantly from those in which no gap is present in the model. The new model was applied to an extreme (beyond design basis) scenario in order to observe the behavior of the fuel during a large prompt critical reactivity insertion. Although a large amount of fission energy was deposited rapidly into the fuel, the kernel temperature is shown to stay well below the melting point and the silicon carbide layer remained well below the temperature above which failure is expected to occur. The explicit treatment of the TRISO particle geometry leads to much lower estimations of power peaking during the transient and a greater degree of negative Doppler feedback.

In this paper, we investigated the crystalline phase of three polymers (polybenzimidazole (PBI), bis(isobutylcarboxy)polybenzimidazole (PBI-Butyl), and Kapton[TM]) and interactions between gas molecules (CO sub(2 and N) sub(2)) and these polymers. A novel, molecular dynamics (MD) based, computational technique was employed to find unknown crystalline structures of these polymer materials. The interaction of CO sub(2 and N) sub(2) gases with these crystals was studied by first-principles calculations and by classical MD simulations.

16088495 AB - Was the death of the Yucca Mountain repository the fate of a technical lemon or a political lemon? We must be careful not to let this debate lure us away from capitalizing on the fruits of the project. One such fruit is a system for safely sealing packages containing radioactive nuclear waste. In March 2009, Idaho National Laboratory (INL) successfully demonstrated the Waste Package Closure System (WPCS), a full-scale prototype system for closing waste packages (WPs) that were to be entombed in the now-abandoned Yucca Mountain repository. This paper describes the system and components, which INL designed and built, to weld the closure lids on the WPs, nondestructively examine the welds using four different techniques, repair the welds if necessary, mitigate crack-initiating stresses in the surfaces of the welds, evacuate and backfill the WPs with an inert gas, and perform all of these tasks remotely. As a nation, we now have a proven method for securely sealing nuclear WPs for long-term storage-regardless of whether the future destination for these WPs will be an underground repository. Additionally, many of the WPCS's features and concepts may benefit other remote nuclear applications.

ER - TY - JOUR T1 - Cesium isotope ratios as indicators of nuclear power plant operations AN - 902355732; 15701931 AB - There are multiple paths by which radioactive cesium can reach the effluent from reactor operations. The radioactive super(135Cs/) super(1)37Cs ratios are controlled by these paths. In an effort to better understand the origin of this radiation, these super(135Cs/) super(1)37Cs ratios in effluents from three power reactor sites have been measured in offsite samples. These ratios are different from global fallout by up to six fold and as such cannot have a significant component from this source. A cesium ratio for a sample collected outside of the plant boundary provides integration over the operating life of the reactor. A sample collected inside the plant at any given time can be much different from this lifetime ratio. The measured cesium ratios vary significantly for the three reactors and indicate that the multiple paths have widely varying levels of contributions. There are too many ways these isotopes can fractionate to be useful for quantitative evaluations of operating parameters in an offsite sample, although it may be possible to obtain limited qualitative information for an onsite sample.

A variety of densification systems are considered for producing a uniform format feedstock commodity for bioenergy applications, including (i) pellet mill, (ii) cuber, (iii) screw extruder, (iv) briquette press, (v) roller press, (vi) tablet press, and (vii) agglomerator. Each of these systems has varying impacts on feedstock chemical and physical properties, and energy consumption. This review discusses the suitability of these densification systems for biomass feedstocks and the impact these systems have on specific energy consumption and end-product quality. For example, a briquette press is more flexible in terms of feedstock variables where higher moisture content and larger particles are acceptable for making good quality briquettes; or among different densification systems, a screw press consumes the most energy because it not only compresses but also shears and mixes the material. Pre-treatment options like pre-heating, grinding, steam explosion, torrefaction, and ammonia fiber explosion (AFEX) can also help to reduce specific energy consumption during densification and improve binding characteristics. Binding behavior can also be improved by adding natural binders, such as proteins, or commercial binders, such as lignosulfonates. The quality of the densified biomass for both domestic and international markets is evaluated using PFI (United States standard) or CEN (European standard).

ER - TY - JOUR T1 - Forward and inverse bio-geochemical modeling of microbially induced calcite precipitation in half-meter column experiments AN - 1803779982; 2016-060765 AB - Microbially induced calcite precipitation (MICP) offers an alternative solution to a wide range of civil engineering problems. Laboratory tests have shown that MICP can immobilize trace metals and radionuclides through co-precipitation with calcium carbonate. MICP has also been shown to improve the undrained shear response of soils and offers potential benefits over current ground improvement techniques that may pose environmental risks and suffer from low "certainty of execution." Our objective is to identify an effective means of achieving uniform distribution of precipitate in a one-dimensional porous medium. Our approach involves column experiments and numerical modeling of MICP in both forward and inverse senses, using a simplified reaction network, with the bacterial strain Sporoscarcina pasteurii. It was found that the stop-flow injection of a urea- and calcium-rich solution produces a more uniform calcite distribution as compared to a continuous injection method, even when both methods involve flow in opposite direction to that used for bacterial cell emplacement. Inverse modeling was conducted by coupling the reactive transport code TOUGHREACT to UCODE for estimating chemical reaction rate parameters with a good match to the experimental data. It was found, however, that the choice of parameters and data was not sufficient to determine a unique solution, and our findings suggest that additional time and space-varying analytical data of aqueous species would improve the accuracy of numerical modeling of MICP.

Cross-sectional TEM results show strong evidence of plasticity via dislocations produced directly from surface grinding and polishing. These dislocations were found to glide on the [inline image] slip system. Using nanoindentation to observe the effects of surface dislocation density, a critical shear stress was found that relates to dislocations nucleation and multiplication. Continued chemo-mechanical polishing increased the critical shear stress to approximately 1600 mN by reducing surface dislocations. It is postulated that vacancy clusters and oxide microcrystallites produced during surface processing provide dislocation nucleation and/or multiplication sites. Gentle chemo-mechanical polishing for several hours greatly reduced or eliminated preexisting dislocations such that the critical shear stress for nucleation approaches the theoretical limit ([approx]G/5).

It has also been proposed for use in geotechnical engineering for soil strengthening applications. Monitoring the occurrence, spatial distribution, and temporal evolution of calcium carbonate precipitation in the subsurface is critical for evaluating the performance of this technology and for developing the predictive models needed for engineering application. In this study, we conducted laboratory column experiments using natural sediment and groundwater to evaluate the utility of geophysical (complex resistivity and seismic) sensing methods, dynamic synchrotron x-ray computed tomography (micro-CT), and reactive transport modeling for tracking ureolytically-driven calcium carbonate precipitation processes under site relevant conditions. Reactive transport modeling with TOUGHREACT successfully simulated the changes of the major chemical components during urea hydrolysis. Even at the relatively low level of urea hydrolysis observed in the experiments, the simulations predicted an enhanced calcium carbonate precipitation rate that was 3-4 times greater than the baseline level. Reactive transport modeling results, geophysical monitoring data and micro-CT imaging correlated well with reaction processes validated by geochemical data. In particular, increases in ionic strength of the pore fluid during urea hydrolysis predicted by geochemical modeling were successfully captured by electrical conductivity measurements and confirmed by geochemical data. The low level of urea hydrolysis and calcium carbonate precipitation suggested by the model and geochemical data was corroborated by minor changes in seismic P-wave velocity measurements and micro-CT imaging; the latter provided direct evidence of sparsely distributed calcium carbonate precipitation. Ion exchange processes promoted through NH4 + production during urea hydrolysis were incorporated in the model and captured critical changes in the major metal species. The electrical phase increases were potentially due to ion exchange processes that modified charge structure at mineral/water interfaces. Our study revealed the potential of geophysical monitoring for geochemical changes during urea hydrolysis and the advantages of combining multiple approaches to understand complex biogeochemical processes in the subsurface.

Vegetation cover and the amount of bare ground are important factors in understanding the sustainability of many ecosystems. Methods that improve speed and cost efficiency could greatly improve how biotic resources are monitored on western lands. Sagebrush steppe ecosystems provide important habitat for a variety of species including sage grouse and pygmy rabbit. Improved methods of monitoring these habitats are needed because not enough resource specialists or funds are available for comprehensive on-the-ground evaluations. In this project, two UAV platforms, fixed-wing and helicopter, were used to collect still-frame imagery to assess vegetation cover in sagebrush steppe ecosystems. This paper discusses the process for collecting and analyzing imagery from the UAVs to 1) estimate percentage of cover for six different vegetation types (shrub, dead shrub, grass, forb, litter, and bare ground) and 2) locate sage grouse using representative decoys. The field plots were located on the Idaho National Laboratory site west of Idaho Falls, Idaho, in areas with varying amounts and types of vegetation cover. A software program called SamplePoint was used along with visual inspection to evaluate percentage of cover for the six cover types. Results were compared against standard field measurements to assess accuracy. The comparison of fixed-wing and helicopter UAV technology against field estimates shows good agreement for the measurement of bare ground. This study shows that if a high degree of detail and data accuracy is desired, then a helicopter UAV may be a good platform to use. If the data collection objective is to assess broad-scale landscape level changes, then the collection of imagery with a fixed-wing system is probably more appropriate.

Spheres as well as cylinders with length to radius ratios of 1.82 are computationally built to consist of 60 vol.% fuel and 40 vol.% metal matrix. Within the geometries, the uranium is enriched to 93 wt.% uranium-235 and the rhenium content within the metal alloy was modeled over the range of 0-30 at.%. The spheres containing UO) sub(2) were determined to have a critical radius of 18.29-19.11 cm and a critical mass ranging from 366 kg to 424 kg. The cylinders containing UO sub(2 were found to have a critical radius ranging from 17.07 cm to 17.84 cm with a corresponding critical mass of 406-471 kg. Spheres engrained with UN were determined to have a critical radius ranging from 14.82 cm to 15.19 cm and a critical mass between 222 kg and 242 kg. Cylinders which were engrained with UN were determined to have a critical radius ranging from 13.81 cm to 14.15 cm and a corresponding critical mass of 245-267 kg. The critical geometries were also computationally submerged in a neutronically infinite medium of fresh water to determine the effects of rhenium addition on criticality accidents due to water submersion. The Monte Carlo analysis demonstrated that rhenium addition of up to 30 at.% can reduce the excess reactivity due to water submersion by up to $5.07 for UO) sub(2) fueled cylinders, $3.87 for UO sub(2 fueled spheres and approximately $3.00 for UN fueled spheres and cylinders.)

Enhanced capabilities are described, including: UO sub(2) temperature and burnup dependent thermal properties, solid and gaseous fission product swelling, fuel densification, fission gas release, cladding thermal and irradiation creep, cladding irradiation growth, gap heat transfer, and gap/plenum gas behavior during irradiation. This new capability is demonstrated using a 2D axisymmetric analysis of the upper section of a simplified multipellet fuel rod, during both steady and transient operation. Comparisons are made between discrete and smeared-pellet simulations. Computational results demonstrate the importance of a multidimensional, multipellet, fully-coupled thermomechanical approach. Interestingly, many of the inherent deficiencies in existing fuel performance codes (e.g., 1D thermomechanics, loose thermomechanical coupling, separate steady and transient analysis, cumbersome pre- and post-processing) are, in fact, ABAQUS strengths.

Microscopy examination was conducted on specimens irradiated to 4 dpa at 505 degree C, 28 dpa at 384 degree C and 155 dpa at 443 degree C where quoted temperatures are the average operating temperatures over the lifetime of the duct. The dislocation and phase microstructure were observed to remain relatively unchanged at 4 dpa at 505 degree C, but significant microstructural changes were observed to have occurred at 28 and 155 dpa and 384 and 443 degree C respectively. At these doses the microstructures have experienced precipitation and formation of interstitial loops. In addition, void swelling had occurred at 155 dpa with an average swelling of [not, vert, similar]0.3%, although some local areas swelled as much as 1.2%. In general it appears that this alloy retains its swelling resistance under typical reactor operation conditions up to 155 dpa.

A simple device is described that collects semi-volatile organic compounds from fixed surfaces by creating an enclosed volume over the surface, then generating a modest vacuum. A solid-phase microextraction (SPME) fiber is then inserted into the evacuated volume where it functions to sorb volatilized organic contaminants. The device is based on a syringe modified with a seal that is used to create the vacuum, with a perforable plunger through which the SPME fiber is inserted. The reduced pressure speeds partitioning of the semi-volatile compounds into the gas phase and reduces the boundary layer around the SPME fiber, which enables a fraction of the volatilized organics to partition into the SPME fiber. After sample collection, the SPME fiber is analyzed using conventional gas chromatography/mass spectrometry. The methodology has been used to collect organophosphorus compounds from glass surfaces, to provide a simple test for the functionality of the devices. Thirty minute sampling times ( Delta T sub(vac)) resulted in fractional recovery efficiencies that ranged from 10 super(-3) to 10 super(-2), and in absolute terms, collection of low nanograms was demonstrated. Fractional recovery values were positively correlated to the vapor pressure of the compounds being sampled. Fractional recovery also increased with increasing Delta T sub(vac) and displayed a roughly logarithmic profile, indicating that an operational equilibrium is being approached. Fractional recovery decreased with increasing time between exposure and sampling; however, recordable quantities of the phosphonates could be collected three weeks after exposure.

Both the German pebble bed reactors produced graphite dust that contained activated elements. These activation products constitute an additional source term of radiation and must be taken under consideration during the conduct of accident analysis of the design. This paper discusses the available literature on graphite dust production and measurements in pebble bed reactors. Limited data is available on the graphite dust produced from the AVR and THTR-300 pebble bed reactors. Experiments that have been performed on wear of graphite in pebble-bed-like conditions are reviewed. The calculation of contact forces, which are a key driving mechanism for dust in the reactor, are also included. In addition, prior graphite dust predictions are examined, and future areas of research are identified. We review potential sources of the graphite dust found in the German pebble bed reactors. Available literature on graphite wear coefficients in pebble bed core-like conditions is reviewed. Limited conclusions and remaining open questions are discussed.

The calculations reveal that intergranular porosity has a significantly higher resistance to heat transfer compared to randomly-distributed porosity. A model is developed to describe this conductivity reduction that considers an effective grain boundary Kapitza resistance as a function of the fractional coverage of grain boundaries by bubbles.

This paper evaluates the ability for membranes to separate DME from syn-gas components, such as H sub(2 and CO. Separations from CO) sub(2) and CH sub(4 also are discussed. Experiments performed include permeability and selectivity of these gases through poly(4-methyl-1-pentene) (TPX) and poly(dimethylsiloxane) (PDMS) using variable temperature mixed gas experiments. The DME data is the first to be reported through these membranes. In this paper, the chosen polymers reflect both rubbery and semicrystalline materials. Rubbery polymers tend to be weakly size sieving, which, in this work, has resulted in larger permeabilities, lower separation factors, and lower activation energies of permeation (E) sub(p)). Conversely, the semicrystalline TPX membranes showed much greater sensitivity to penetrant size; although the gas condensability also played a role in transport.

More recently, some microorganisms have been examined for their role in immobilization of U(VI) via precipitation of uranyl phosphate minerals mediated by microbial phosphate release, alleviating the requirement for long-term redox control. Here, we investigated the mechanism of U(VI) removal mediated by an environmental isolate, strain UFO1, that is indigenous to the Field Research Center (FRC) in Oak Ridge, TN and has been detected in U(VI)-contaminated sediments. Changes in U(VI) speciation were examined in the presence and absence of the electron-shuttling moiety, anthraquinone-2,6-disulfonate (AQDS). Cell suspensions were capable of nearly complete removal of 100mu M U(VI) from solution within 48h; U(VI) removal was not dependent on the presence of an exogenous electron donor or AQDS, although AQDS increased the rate of U(VI) removal. X-ray Absorption Near Edge Structure (XANES) and Extended X-ray Absorption Fine Structure (EXAFS) spectroscopic measurements indicated that U(IV) was the predominant oxidation state of uranium in cell suspensions in both the absence and presence of 100mu M AQDS. Interestingly, 17% of the cell-associated precipitates in a U(VI)-treated suspension that lacked AQDS had spectral characteristics consistent with a uranyl phosphate solid phase. The potential involvement of phosphate was consistent with observed increases in soluble phosphate concentrations over time in UFO1 cell suspensions, which suggested phosphate liberation from the cells. TEM-EDS confirmed the presence of uranyl phosphate with a U:P ratio consistent with autunite (1:1). EXAFS analyses further suggested that U(IV) was bound to low-Z neighbors such as C or P, inferred to be present as functional groups on biomass. These results suggest that strain UFO1 has the ability to facilitate U(VI) removal from solution via reductive and phosphate precipitation mechanisms. Both mechanisms offer potential for the remediation of U-contaminated sediments at the FRC or elsewhere.

To improve the understanding of the as-fabricated microstructures of U-Mo dispersion fuel plates, particularly the interaction layers that can form between the fuel particles and the matrix, scanning electron microscopy (SEM) and transmission electron microscopy (TEM) analyses have been performed on samples from depleted U-7Mo (U-7Mo) dispersion fuel plates with either Al-2 wt.% Si(Al-2Si) or AA4043 alloy matrix. It was observed that in the thick interaction layers, U(Al, Si)3 and U6Mo4Al43 were present, and in the thin interaction layers, (U, Mo) (Al, Si)3, U(Al, Si)4, U3Si3Al2, U3Si5, and possibly USi-type phases were observed. The U3Si3Al2 phase contained some Mo. Based on the results of this investigation, the time that a dispersion fuel plate is exposed to a relatively high temperature during fabrication will impact the nature of the interaction layers around the fuel particles. Uniformly thin, Si-rich layers will develop around the U-7Mo particles for shorter exposure times, and thicker, Si-depleted layers will develop for the longer exposure times.

Three depleted uranium alloys were cast that consisted of the following five phases to be investigated: U(Si, Al) sub(3), (U, Mo)(Si, Al) sub(3), UMo sub(2)Al sub(20), U sub(6)Mo sub(4)Al sub(43), and UAl sub(4). Irradiation of transmission electron microscopy (TEM) disc samples with 500-keV Kr ions at 200 degree C to doses up to [inline image]100 displacements per atom (dpa) were conducted using a 300-keV electron microscope equipped with an ion accelerator. TEM results show that the U(Si, Al) sub(3) and UAl sub(4) phases remain crystalline at 100 dpa without forming voids. The (U, Mo)(Si, Al) sub(3) and UMo sub(2)Al sub(20) phases become amorphous at 1 and [inline image]2 dpa, respectively, and show no evidence of voids at 100 dpa. The U sub(6)Mo sub(4)Al sub(43) phase goes to amorphous at less than 1 dpa and reveals high density voids at 100 dpa.

However, as a new technology in the process of moving toward commercial development, it is important to understand obstacles to its development. We focused on the role that policy may be playing in fostering or impeding its development in the U.S. One of the major ways of understanding technological development is the theory of the diffusion of innovation. This theory identifies factors that can impede and facilitate this diffusion. We assessed the degree to which three of the main U.S. federal energy policies aim at addressing three key aspects of innovation diffusion: time; risk; and communication. We determine that these policies focus more on the producer stage of the lignocellulosic ethanol lifecycle than the landowner or consumer stages.

Finally, they contain at least one provision likely to be a serious impediment to adoption.

We have studied performance quantities including conductivity, viscosity, flash point, and electrochemical window of electrolytes as well as formation of solid electrolyte interphase (SEI) films. In the course of study, the necessity for a simple method of SEI characterization was realized. Therefore, a new method and new criteria were developed and validated on 10 variations of electrolyte/electrode substrates. Based on the summation of determined physical and electrochemical properties of phosphazene-based electrolytes, one structure of phosphazene compound was found better than the other. This capability helps to direct our further synthetic work in phosphazene chemistry.

To better understand the foremost influences on path dependence in the PHEV context, this work aims to bridge the gap between ideal laboratory test conditions and PHEV field conditions by isolating the predominant aging factors in PHEV service, which would include, for example, the nature and frequency of duty cycles, as well as the frequency and severity of thermal cycles. These factors are studied in controlled and repeatable laboratory conditions to facilitate mechanistic evaluation of aging processes. This work is a collaboration between Idaho National Laboratory (INL) and the Hawaii Natural Energy Institute (HNEI). Commercial lithium-ion cells of the Sanyo Y type (18650 configuration) are used in this work covering two initial independent studies of path dependence issues. The first study considers how the magnitude of power pulses and charging rates affect the aging rate, while the second seeks to answer whether thermal cycling has an accelerating effect on cell aging. While this work is in early stages of testing, initial data trends show that cell aging is indeed accelerated under conditions of high discharge pulse power, higher charge rates, and thermal cycling. Such information is useful in developing accurate predictive models for estimating end-of-life conditions.

Several of these specimens were fatigued in the near threshold, and steady state regimes of Paris Law behavior. Additionally, two specimens were fatigued to the edge of the nickel interlayer and then monotonically loaded. Micro-hardness profiles of the nickel interlayer were also measured. Fatigue behavior was found to be similar to previous studies in that arrest was only noted in the near threshold Paris regime (attributed to the presence of voids) and in the steady state regime exhibited an acceleration of crack growth rate through the nickel interlayer followed by a slight retardation. Monotonic loading resulted in crack branching or delamination along the interlayer. Although archival material was not available for this study, the hardness of the nickel interlayer was determined to have been lowered slightly during service by comparison to the expected hardness of a similar nickel braze prepared as specified for fabrication of these tubes.

Due to the high power density in the reactor core, heat removal requirements encourage the use of high-heat-transfer coolants such as liquid sodium. The variation of power across the core requires ducted assemblies to control fuel and coolant temperatures, which are also used to constrain core geometry. In a fast reactor, the fuel is not in the most neutronically reactive configuration during normal operation. Accidents leading to fuel melting, fuel pin failure, and fuel relocation can result in positive reactivity, increasing power, and possibly resulting in severe accident consequences including recriticalities that could threaten reactor and containment integrity. Inherent safety concepts, including favorable reactivity feedback, natural circulation cooling, and design choices resulting in favorable dispersive characteristics for failed fuel, can be used to increase the level of safety to the point where it is highly unlikely, or perhaps even not credible, for such severe accident consequences to occur.

Phenomena identification and ranking studies to date have ranked an air-ingress event, following on the heels of a VHTR depressurization, as important with regard to core safety. Consequently, the development of advanced air-ingress-related models and verification and validation data are a very high priority. Following a loss of coolant and system depressurization incident, air will enter the core of the high-temperature gas-cooled reactor through the break, possibly causing oxidation of the core and reflector graphite structure. Simple core and plant models indicate that, under certain circumstances, the oxidation may proceed at an elevated rate with additional heat generated from the oxidation reaction itself. Under postulated conditions of fluid flow and temperature, excessive degradation of lower plenum graphite because of oxidation might lead to a reactor safety issue. Computational fluid dynamics models developed in this study will improve our understanding of this phenomenon and is used to mitigate air ingress. This paper presents three-dimensional (3D) computational fluid dynamic (CFD) results for the quantitative assessment of the air-ingress phenomena. The 3D CFD simulation results show that the air-ingress accident is not controlled by molecular diffusion but density gradient driven stratified flow when the double-ended-guillotine break is assumed in a horizontal pipe configuration. It concludes that the previous air-ingress scenarios based on the molecular diffusion might not be correct and should be extensively modified to include real phenomena. This paper also presents a preliminary two-dimensional (2D) CFD simulation for validating an air-ingress mitigation concept using helium injection at the lower plenum. This simulation shows that the helium replaces air by buoyancy force and effectively mitigates air-ingress into the core.

The report was prepared in support of providing data for preparation of a NEPA Environmental Impact Statement in support the U.S. Department of Energy (DOE) Global Nuclear Energy Partnership (GNEP). One of the GNEP objectives was to reduce the inventory of long lived actinide from the light water reactor (LWR) spent fuel. The LWR spent fuel contains Plutonium (Pu)-239 and other transuranics (TRU) such as Americium-241. One of the options is to transmute or burn these actinides in fast neutron spectra as well as generate the electricity. A sodium-cooled Advanced Recycling Reactor (ARR) concept was proposed to achieve this goal. However, fuel with relatively high TRU content has not been used in the fast reactor. To demonstrate the utilization of TRU fuel in a fast reactor, an Advanced Burner Reactor (ABR) prototype of ARR was proposed, which would necessarily be started up using weapons grade (WG) Pu fuel. The WG Pu is distinguished by relatively highest proportions of Pu-239 and lesser amount of other actinides. The WG Pu was assumed to be used as the startup fuel along with TRU fuel in lead test assemblies. Because such fuel is not currently being produced in the US, a new facility (or new capability in an existing facility) was being considered for fabrication of WG Pu fuel for the ABR.

Simulated steady-state flow fields were analyzed using backward particle-tracking simulations that were based on a modified version of the particle tracking program MODPATH. The model adequately simulated the areal shape of the 5 microgram per liter lithium contour interpreted to represent the transition from a water type that is primarily composed of tributary valley underflow and streamflow infiltration recharge to a water type primarily composed of regional aquifer underflow. Inconsistences between model- and independently-derived estimates of water type separation in the southern portion of the model area may indicate model error, where unreasonable estimates of hydraulic conductivity result in an over displacement of tributary valley water by the relatively fast moving regional aquifer water. Sources of water at well NPR-W01 were identified using backward particle tracking, and they were compared to the relative percentages of source water chemistry determined using geochemical mass balance and mixing models. The particle tracking results show a good comparison with chemistry results for surface water sources (10 percent difference); however, regional aquifer sources were significantly overestimated by the model. The water samples used in the chemistry analysis were collected from an isolated depth interval in the upper 10 feet of the aquifer, an area likely absent of deeper regional groundwater; whereas, the simulated particles were released in the upper 200 feet of the aquifer to account for a modeled spatial discretization that is too coarse to precisely represent the dimensions of this sampling zone. Independently-derived estimates of the average linear velocity of the young fraction of groundwater within the upper 100 feet of the aquifer were compared to model-derived estimates of the average particle velocity at 23 well locations. A comparison was only possible where velocity estimates were based on equivalent geographical source areas; 12 of the 23 wells met this criterion. Discrepancies between source areas were attributed to: (1) independently-derived estimates of travel time that were only available for young groundwater, (2) the insensitivity of particle tracking simulations to weak-source cells, and (3) model error. Differences between velocity estimates for equivalent source areas ranged from -9.6 to 36.1 feet per day, indicating good agreement; although, velocity differences of 29.9 and 36.1 feet per day for wells USGS 1 and 100, respectively, may indicate an overestimation of the hydraulic conductivity for hydrogeologic zone 1.

Co.) were irradiated by high flux neutrons at 323 K to 0.025 dpa in High Flux Isotope Reactor (HFIR) at Oak Ridge National Laboratory (ORNL). Subsequently, one of the neutron-irradiated tungsten samples was exposed to a high-flux deuterium plasma (ion flux: 5 x 10(21) m(-2)s(-1), ion fluence: 4 x 10(25) m(-2)) in the Tritium Plasma Experiment (TPE) at Idaho National Laboratory (INL). The deuterium retention in the neutron-irradiated tungsten was 40% higher in comparison to the unirradiated tungsten. The observed broad desorption spectrum from neutron-irradiated tungsten and associated TMAP modeling of the deuterium release suggest that trapping occurs in the bulk material at more than three different energy sites.

The success of engineered precipitation schemes depends on the particular phases generated, their rates of formation, and their long term stability. The purpose of this study was to examine the precipitation of calcium phosphate minerals under conditions representative of a natural groundwater. Because microorganisms are present in groundwater, and because some proposed schemes for phosphate mineral precipitation rely on stimulation of native microbial populations, we also tested the effect of bacterial cells (initial densities of 10 super(5 )and 10 super(7 )mL super(-1)) added to the precipitation medium. In addition, we tested the effect of a trace mixture of propionic, isovaleric, formic and butyric acids (total concentration 0.035 mM). Results: The general progression of mineral precipitation was similar under all of the study conditions, with initial formation of amorphous calcium phosphate, and transformation to poorly crystalline hydroxylapatite (HAP) within one week. The presence of the bacterial cells appeared to delay precipitation, although by the end of the experiments the overall extent of precipitation was similar for all treatments. The stoichiometry of the final precipitates as well as Rietveld structure refinement using x-ray diffraction data indicated that the presence of organic acids and bacterial cells resulted in an increasing a and decreasing c lattice parameter, with the higher concentration of cells resulting in the greatest distortion. Uptake of Sr into the solids was decreased in the treatments with cells and organic acids, compared to the control. Conclusions: Our results suggest that the minerals formed initially during an engineered precipitation application for trace element sequestration may not be the ones that control long-term immobilization of the contaminants. In addition, the presence of bacterial cells appears to be associated with delayed HAP precipitation, changes in the lattice parameters, and reduced incorporation of trace elements as compared to cell-free systems. Schemes to remediate groundwater contaminated with trace metals that are based on enhanced phosphate mineral precipitation may need to account for these phenomena, particularly if the remediation approach relies on enhancement of in situ microbial populations.

For most environmentally relevant conditions this exchange involves interaction between soluble ferrous iron and solid-phase iron oxides and oxyhydroxides, with complex involvement of solid-state charge migration. Examples include Fe (II)-catalyzed transformation of Fe (III)-oxides and oxyhydroxides, and spinel ferrite nanoparticles acting as a mineralogic source and sink for reactive Fe (II) due to their topotactic solid-solution property and stable multi-valent nature. This presentation focuses on the interdependence of Fe (II) fluxes at these mineral-water interfaces with structural and electronic properties of mineralogic iron oxide forms. Using combined experiment and computational molecular simulation, we examine the underlying mechanisms of observed complete iron atom exchange without change in mineralogy, crystallinity, crystal size or shape between an aqueous Fe (II) pool and well-defined goethite (FeOOH) crystallites, the accessibility of solid-state Fe (II) in titanomagnetite (Fe (sub 3-x) Ti (sub x) O (sub 4) ) nanoparticles in which the structural Fe (II)/Fe (III) ratio is intentionally tuned by the Ti (IV) content, and the highly time-resolved dynamics and fate of Fe (II) electrons photoinjected into maghemite (Fe (sub 8/3) O (sub 4) ) nanoparticles. Aspects covered will include thermodynamic energy requirements for bulk crystal conduction and possible free energy sources sustaining bulk currents, ferrous iron adsorption energies at iron oxide surfaces and the kinetics of interfacial electron exchange, the structural dependence of ferrous-ferric electron exchange in the solid, and internal charge compensation mechanisms. These lines of research are collectively converging on a picture of rapid electron exchange dynamics between aqueous ferrous iron and iron oxides, with broad-reaching implications for the biogeochemistry iron in the subsurface.

The observed half-maximal inhibitory concentrations (IC50), +/- 95% confidence intervals, for Pb, Zn, and Cu were 0.9 +/- 0.1 mM, 39 +/- 0.5 mM, and 120 +/- 8 mM, respectively. The observed minimum inhibitory concentrations (MIC) for Pb, Zn, and Cu were 7.5 mM, 75 mM, and 250 mM, respectively. When metals were presented in binary mixtures, the toxicities were less than additive. For example, when 50% of the Pb MIC and 50% of the Cu MIC were presented together, the specific growth rate was inhibited by only 59 +/- 3%, rather than 100%. In addition, the presence of ferrous iron in the growth media decreased Pb and Zn toxicity to A. caldus strain BC13. The importance of inoculum history was evaluated by pre-adapting cultures through subsequent transfers in the presence of Pb, Zn, and Cu at their respective IC50s. After pre-adaptation, cultures had specific growth rates 39 +/- 11, 32 +/- 7, and 28 +/- 12% higher in the presence of Pb, Zn, and Cu IC50s, respectively, compared with cultures that had not been pre-adapted. In addition, when cells exposed to the MICs of Pb, Zn, and Cu were harvested, washed, and re-inoculated into fresh, metal-free medium, they grew, showing that the cells remained viable with little residual toxicity. Finally, metal chlorides showed more toxicity than metal sulfates, and studies using sodium chloride or a mixture of metal sulfates and sodium chloride suggested that this was attributable to an additive combination of the metal and chloride toxicities.

For dispersion type fuels, radiation stability of the fuel-cladding interaction product has a strong impact on fuel performance. Three depleted-uranium alloys are cast for the radiation stability studies of the fuel-cladding interaction product using Kr ion irradiation to investigate radiation damage from fission products. SEM analysis indicates the presence of the phases of interest: U(Al, Si) sub(3), (U, Mo)(Al, Si) sub(3), UMo sub(2)Al sub(20), U sub(6)Mo sub(4)Al sub(43) and UAl sub(4). Irradiations of TEM disc samples were conducted with 500 keV Kr ions at 200 degree C to ion doses up to 2.5 x 10 super(19) ions/m super(2) (10 dpa) with an Kr ion flux of 10 super(16) ions/m super(2)/s (4.0 x 10 super(-3) dpa/s). Microstructural evolution of the phases relevant to fuel-cladding interaction products was investigated using transmission electron microscopy.

Dry bag isostatically pressed rods of a fuel surrogate (95% CeO sub(2)-5% HfO sub(2)) 200 mm long by 8 mm diameter were cut into pellets using a wire saw. Four different binders and CeO sub(2) powder obtained from two different sources were investigated. The strength of the isostatically pressed pellets for all binder systems measured by diametral compression was about 50% higher than pellets produced by uniaxial dry pressing at the same pressure. It was proposed that the less uniform density of uniaxially pressed pellets accounted for the lower strength. The strength of pellets containing CeO sub(2) powder with significantly higher moisture content was five times higher than pellets containing CeO sub(2) powder with a low moisture content even though they were 25% less dense. Capillary pressure of the moisture was thought to supply the added binding strength.

Of the environmental aspects, the impacts of greenhouse gas mitigation strategies on water quantity and quality is poorly understood. Some strategies will increase water demand per unit energy, while others will decrease water requirements. If we accept that continued population growth will increase overall energy demand, and that global freshwater resources are already being utilized at unsustainable rates, then it becomes apparent that climate mitigation strategies must also reduce water demand for energy as well as impacts of energy on water quality. This paper will revisit the "Climate Stabilization Wedges" first proposed by Pacala and Socolow in 2004; and evaluate their impacts on water requirements for energy. We will present water impact "wedges" to augment the climate stabilization wedges; and identify which strategies are most likely to be sustainable from a water impacts perspective. We will also identify new wedges, not discussed by Pacala and Socolow, which address both the carbon and water aspects of sustainable energy production JF - Abstracts with Programs - Geological Society of America AU - Cooper, Craig AU - Sehlke, Gerald AU - Anonymous Y1 - 2010/11// PY - 2010 DA - November 2010 SP - 605 PB - Geological Society of America (GSA), Boulder, CO VL - 42 IS - 5 SN - 0016-7592, 0016-7592 KW - mitigation KW - technology KW - development KW - energy sources KW - global KW - fresh water KW - policy KW - greenhouse gases KW - water resources KW - climate change KW - demand KW - 29A:Economic geology, geology of energy sources KW - 21:Hydrogeology UR - http://libproxy.lib.unc.edu/login?url=http://search.proquest.com/docview/902084368?accountid=14244 L2 - http://vb3lk7eb4t.search.serialssolutions.com/?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQ%3Ageorefmodule&rft_val_fmt=info:ofi/fmt:kev:mtx:journal&rft.genre=article&rft.jtitle=Abstracts+with+Programs+-+Geological+Society+of+America&rft.atitle=Environmental+constraints+to+energy+development%3B+impact+of+water+resource+limitations+on+climate+mitigation&rft.au=Cooper%2C+Craig%3BSehlke%2C+Gerald%3BAnonymous&rft.aulast=Cooper&rft.aufirst=Craig&rft.date=2010-11-01&rft.volume=42&rft.issue=5&rft.spage=605&rft.isbn=&rft.btitle=&rft.title=Abstracts+with+Programs+-+Geological+Society+of+America&rft.issn=00167592&rft_id=info:doi/ LA - English DB - GeoRef N1 - Conference title - Geological Society of America, 2010 annual meeting N1 - Copyright - GeoRef, Copyright 2012, American Geosciences Institute.

Global change--e.g., population growth and migration, changes in land and water use, and climate change are putting unprecedented demands on our natural resources. In addition, the unprecedented number of scientists and resource professionals retiring, the growing national deficit and the political rancor and partisanship being exhibited nation-wide are all contributing to the challenges being faced by geoscientist. The question at hand is how can natural resources professionals develop opportunities from these challenges, how can we sustainably manage the nation's natural resources in the face of potential chaos? In the water resources field, understanding the hydrology and geology of a basin is not nearly enough to manage water in a basin or watershed that is under stress from global changes. We need to understand the physical system with its opportunities and constraints; however, we also need to understand the political, socioeconomic, legal, biological, and cultural opportunities and constraints. Geoscientists generally focus on developing or improving our understanding the hydrological "capacity" of the basin, i.e., how much water is actually physically available where and when. However, they also need to understand how potential water use is constrained by legal constrains (e.g., water law, compacts and treaties) and socioeconomic constraints; or conversely, what opportunities can be driven by public acceptance and political will. Not only do geoscientists need to understand these issues, but they need to help inform managers and decision makers the scientific opportunities, constraints and needs, in the context of the physical, socioeconomic and legal realities to help build more efficient, resilient and adaptive water management systems in the future.

However, the advancement of EGS greatly depends on the ability to create a reservoir of sufficient volume by hydraulic fracturing, via tensile and shear failure, and also by reactivation of naturally existing fractures, to allow for commercial-scale heat transfer from the reservoir rocks to the working fluid. Our understanding of the dynamics of the coupled rock-fracture-fluid-heat system, and our ability to reliably predict how reservoirs behave under stimulation and production, are currently limited by the computational capabilities of existing simulators. In order to advance our understanding of how reservoirs behave under these conditions, we are developing a coupled physics-based hybrid Finite Element (FE)-Discrete Element (DEM) simulator for continuum multiphase flow and heat transport (FE) and rock deformation-fracture propagation (DEM). In our approach, the continuum flow and heat transport equations are solved on an underlying finite element mesh with evolving porosity and permeability for each element that depends on the local structure of the discrete element network. Here we describe the development of the simulator, detailing the development of a parallel, fully coupled, multiphase thermo-hydro-mechanical simulation code and present results of initial code comparisons using conditions representative of EGS systems.

In this study, we assess LGM climate at high altitude in the southern Rocky Mountains of New Mexico, where climate models also suggest increased LGM moisture. This work represents the first modeling of LGM paleoclimate based on evidence from the small paleoglaciers of the southernmost Rocky Mountains. Reconstruction of LGM glacial ice extents focused on two glacial valleys in the southern Sangre de Cristo Mountains, near Santa Fe. A 2-D numerical model of glacier energy/mass balance and flow (Plummer and Phillips, 2003) was used to evaluate LGM climate. The model yields combinations of changes in precipitation and temperature from present conditions that could have sustained glaciers at their LGM extents. We found that any temperature depression of less than 8.4 degrees C, would have required greater-than-modern precipitation to sustain LGM glaciers. Temperature depressions of 6 degrees C, 7 degrees C, and 8 degrees C would need to have been associated with 2.8x, 1.9x, and 1.3x modern precipitation conditions, respectively. Results also show that temperature depressions of 9 degrees and 10 degrees C would require climate drying, with 0.8x and 0.4x modern precipitation, respectively. Comparison of these results with those of modeling using the same approach in the Rockies further north indicates either that LGM temperature depression was greater in the southernmost Rockies than further north or that precipitation was enhanced in the south. Global and regional climate models suggest that (1) LGM temperature depression in the southern Rockies was no greater, and likely less, than that further north and (2) it is unlikely that in the southern Rockies temperature depression was as great as 8.4 degrees C. Thus, we conclude that an increase in precipitation, relative to modern conditions, was necessary to support the glaciers we modeled in the southernmost Rocky Mountains. Findings from this study encourage future use of the numerical model to investigate LGM climate conditions throughout the U.S. Rocky Mountains.

From hydrous retort experiments and literature surveys, inorganic and organic contaminants were identified that are most likely to be generated during in-situ retorting. From this initial list of contaminants, those that are likely to pose the greatest risk we identified based on their mobility, concentration, and toxicity (from published LD50 values). Mobility, addressed from the sorption characteristics of the compounds, is estimated under the expected subsurface geochemical conditions (pH, Eh, total organic carbon) using published experimental data and linear free energy relationships. Where possible, we have evaluated the effects of temperature dependence of partition coefficients on transport. Geochemical modeling studies are used to estimate equilibrium concentrations of inorganic contaminants as the water returns to ambient temperature. The role of degradation of organic contaminants is discussed. The results provide relative risk for the transport of various contaminants from the near field to the far field. Site-specific time scales can then be estimated and used to calculate minimum degradation rates necessary to keep the contaminants below the maximum allowable concentration limit (MCL) at monitoring wells. Potential contaminants of concern that require additional study are identified.

However, during this heating process, there are concomitant changes in the mineralogical makeup of the rock matrix and chemical composition of subsurface waters that may ultimately alter reservoir permeability or affect the subsurface migration of contaminants. Hydrous pyrolysis experiments were conducted over the temperature range of 25 to 350 degrees C. Quantitative powder X-ray diffraction suggests that ankerite and aragonite are converted to calcite. The Mg and Fe from this conversion combine with Si and Al from analcime and quartz to form smectite (saponite). Retort water is primarily a Na-HCO (sub 3) type water. Dissolved F, B, N, P, Ca, K, Cl and Br increase with retort temperature. Arsenic concentrations were very high in some experiments but the concentrations are not correlated with retort temperature. Geochemical modeling was conducted to provide further insight to the geochemical reactions occurring during retorting. The experimental results are combined with heat-flow calculations to conceptualize the potential spatial extent of geochemical alterations in the native rock and subsurface waters.

Published water consumption estimates ex-situ retorting of oil shale range from 1.6 to 6.2 barrels of water for every barrel of product. This uncertainty in water consumption may be even greater for in situ oil shale development technologies, due to both a paucity of data on which to base water consumption estimates, and a lack of a consistent approach to estimate water quantity needs. Based on surface retorting approaches, we have developed a system dynamics modeling approach to examine the temporal water use for an in-situ oil shale retort for the construction, production, and the reclamation phases. Although this model has been designed for in-situ retort, it has ignored the potential egress of ground water into the retort zone. Our objective in this study is to evaluate the impact of ground water leakage into a retort zone during production and reclamation on the total water consumption estimate of an in-situ oil shale retort. Leakage rates are determined with a Darcy model approach using a range of parameters derived from published literature. The hypothetical oil shale retorting facility used in the model is loosely based on the Shell In-Situ Conversion Process. The results illustrate the impact of leakage on net water usage and the potential need for engineering approaches for controlling ground water egress into retorts.

Self-calibrating systems allow real time data at low cost. A self-calibrating system has been installed at the Barite Hill Pit Lake, an acid mine pit lake with a stratified water column consisting of nearly "clean" water at the top and highly acidic, heavy metal rich water below. The purpose of the monitoring system is to automatically sample and analyze daily for pH, ORP, DO, temperature, and conductivity at 5 foot increments down the profile of the pit lake water column. The four wells located in the waste rock repository south of the lake are also autonomously monitored for the same properties as the pit lake. The system also includes a sonic water level sensor to monitor the pit lake level. This sensor along with a camera mounted to observe the spillway and floating chemical system is used as an early warning system to monitor Lake Overflow. Stainless steel thermocouples are used to collect temperature every ten minutes along the vertical profile in the lake as well as the monitoring wells. Remote site communications is provided by a dedicated two-way cellular modem that allows continuous access to the system for data download software updates, and eventually remote control. The data are recorded on site as well as automatically grabbed by a remote server and parsed into a relational database. A secure web interface provides access to the data from any online computer, has graduated levels of access with multiple permissions levels, basic data analysis, and plotting tools. This type of self-calibrating monitoring systems allows low cost year round access to remote sites that previously has not been achievable. The high data density provides information suitable for the understanding of the complex system dynamics allowing good management and engineering decisions to be possible.

For example, experiments designed to study iron atom exchange dynamics between an aqueous (super 57) Fe(II) pool and a solid phase (super 56) Fe(III) pool in the form of acicular goethite nanorod and larger microrod crystallites implicate interfacial Fe(II) (sub (aq)) -Fe(III) (sub (goe)) electron exchange reactions remotely linked by a net bulk electrical current flow. Complete isotopic exchange in both goethite forms without mineralogy, crystallinity, crystal size or shape change occurs within 30 days at pH 7.5. Indistinguishable exchange rates for nanorods and microrods are consistent with a relatively facile bulk electron conduction step. Notwithstanding, fundamental thermodynamic and molecular-level understanding of this mechanism is so far lacking. The net bulk current requires free energy input to overcome the intrinsically high electrical resistivity of the solid phase ( approximately 10 (super 5) -10 (super 6) Omega . m). It also implies preferential Fe(II) adsorption and electron injection sites, and a separate site type with the opposite preference. Comparison of the estimated free energy driving force available to the system from Gibbs' entropy of (ideal) mixing to the estimated heat dissipation rate in the solid shows that the entropic driving force is sufficient to sustain the observed exchange behavior. Empirical potential molecular dynamics simulations were performed to assess the free energies and activation energies for elementary processes of Fe(II) adsorption, interfacial electron exchange, and subsurface electron migration for common low-index goethite surfaces. The findings show strong inner-sphere Fe(II) adsorption, mildly thermodynamically uphill electron injectivity, and select pathways for electron migration into goethite interiors, with substantial differences in energetic requirements between rod prismatic (side) faces and rod terminal (end) faces. The collective findings are generally consistent with the bulk current mechanism. Further investigation of this mechanism will have important implications for understanding aqueous iron redox transformations, and closely interlinked subsurface biogeochemical processes.

These equations are not hyperbolic, their physical wave dynamics are incorrect, and their solution algorithms rely on dubious truncation error induced artificial viscosity to render them numerically well-posed over a portion of the computational spectrum. The inherent problems of the traditional approach to multiphase modeling, which begins with an averaged system of (ill-posed) partial differential equations (PDEs) which are then discretized to form a numerical scheme, are avoided by employing a new homogenization method known as the discrete equation method (DEM) (Abgrall and Saurel, 2003). This method results in well-posed hyperbolic systems, this property being important for transient flows. This also allows a clear treatment of non-conservative terms (terms involving interfacial variables and volume fraction gradients) permitting the solution of interface problems without conservation errors, this feature being important for the direct numerical simulation of two-phase flows. Unlike conventional methods, the averaged system of PDEs for the mixture are not used, and the DEM method directly obtains a well-posed discrete equation system from the single-phase conservation laws, producing a numerical scheme which accurately computes fluxes for arbitrary number of phases. The method effectively uses a sequence of single-phase Riemann problem solutions. Phase interactions are accounted for by Riemann solvers at each interface. Non-conservative derivative product terms are correctly approximated. Some of the closure relations missing from the traditional approach are automatically obtained. Lastly, the continuous equation system resulting from the discrete equations can be identified by taking the continuous limit with weak-wave assumptions. In this work, this approach is tested by constructing a DEM model for the flow of two compressible phases in 1-D ducts of spatially varying cross-section with explicit time integration. An analytical equation of state is included for both water vapor and liquid phases, and a realistic interphase mass transfer model is developed based on interphase heat transfer. A robust compliment of boundary conditions is developed and discussed. Though originally conceived as a first step toward implict time integration of the DEM method (to relieve time step size restrictions due to stiffness and to achieve tighter coupling of equations) in multidimensions, this model offers some unique capabilities for incorporation into next generation light water reactor safety analysis codes. We demonstrate, on a converging-diverging two-phase nozzle, that this well-posed, 2-pressure, 2-velocity DEM model can be integrated to a realistic and meaningful steady state with both phases treated as compressible.

One promising in situ immobilization approach of these contaminants is engineered mineral (co) precipitation of calcite driven by urea hydrolysis that is catalyzed by the enzyme urease. The tight nonlinear coupling among flow, transport, reaction and reaction-induced property changes of media of this approach was studied by reactive transport simulations with a systematically increasing level of complexities of reaction network and physical/chemical heterogeneities using a numerical simulator named STOMP. Sensitivity studies on the reaction rates of both urea hydrolysis and calcite precipitation are performed via controlling urease enzyme concentration and precipitation rate constant according to the rate models employed. We have found that the rate of ureolysis is a dominating factor in the amount of precipitated mineral; however, the spatial distribution of the precipitates depends on both rates of ureolysis and calcite precipitation. A maximum 5% reduction in the porosity was observed within the simulation time period of 6 pore volumes in our 1-dimensional (1D) column simulations. When a low permeability inclusion is considered in the 2D simulations, the altered flow fields redistribute mineral forming constituents, leading to a distorted precipitation reaction front. The simulations also indicate that mineral precipitation occurs along the boundary of the low permeability zone, which implies that contaminants in the low permeability zone could be encapsulated and isolated from the flow paths.

To achieve this, the macroscale system is solved in a parallel, fully coupled, fully-implicit manner using the preconditioned Jacobian-free Newton Krylov (JFNK) method. Within the JFNK solution algorithm, microstructure-influenced material parameters are calculated by the mesoscale model and passed back to the macroscale calculation. Due to the stochastic nature of the mesoscale model, a dynamic fitting technique is implemented to smooth roughness in the calculated material parameters. The proposed methodology is demonstrated on a simple model of a reactor fuel pellet. In the model, INL's BISON fuel performance code calculates the steady-state temperature profile in a fuel pellet and the microstructure-influenced thermal conductivity is determined with a phase field model of irradiated microstructures. This simple multiscale model demonstrates good nonlinear convergence and near ideal parallel scalability. By capturing the formation of large mesoscale voids in the pellet interior, the multiscale model predicted the irradiation-induced reduction in the thermal conductivity commonly observed in reactors.

The AGR-1 TRISO fuel experiment, currently underway, is the first in a series of eight fuel tests planned for irradiation in the Advanced Test Reactor (ATR) located at the Idaho National Laboratory (INL). The AGR-1 experiment reached a peak compact averaged burnup of 9% FIMA with no known TRISO fuel particle failures in March 2008. The burnup goal for the majority of the fuel compacts is to have a compact averaged burnup greater than 18% FIMA and a minimum compact averaged burnup of 14% FIMA. At the INL the TRISO fuel in the AGR-1 experiment is closely monitored while it is being irradiated in the ATR. The effluent monitoring system used for the AGR-1 fuel is the Fission Product Monitoring System (FPMS). The FPMS is a valuable tool that provides near real-time data indicative of the AGR-1 test fuel performance and incorporates both high-purity germanium (HPGe) gamma-ray spectrometers and sodium iodide [NaI(Tl)] scintillation detector-based gross radiation monitors. To quantify the fuel performance, release-to-birth ratios (R/B's) of radioactive fission gases are computed. The gamma-ray spectra acquired by the AGR-1 FPMS are analyzed and used to determine the released activities of specific fission gases, while a dedicated detector provides near-real time count rate information. Isotopic build up and depletion calculations provide the associated isotopic birth rates. This paper highlights the features of the FPMS, encompassing the equipment, methods and measures that enable the calculation of the release-to-birth ratios. Some preliminary results from the AGR-1 experiment are also presented.

To capture nuclear process heat, and transport it to a distant industrial facility requires a high temperature system of heat exchangers, pumps and/or compressors. The heat transfer system is particularly challenging not only due to the elevated temperatures (up to [inline image]1300 K) and industrial scale power transport (>=50 MW), but also due to a potentially large separation distance between the nuclear and industrial plants (100+ m) dictated by safety and licensing mandates. The work reported here is the preliminary analysis of two-phase thermosyphon heat transfer performance with alkali metals. A thermosyphon is a thermal device for transporting heat from one point to another with quite extraordinary properties. In contrast to single-phased forced convective heat transfer via 'pumping a fluid', a thermosyphon (also called a wickless heat pipe) transfers heat through the vaporization/condensing process. The condensate is further returned to the hot source by gravity, i.e., without any requirement of pumps or compressors. With this mode of heat transfer, the thermosyphon has the capability to transport heat at high rates over appreciable distances, virtually isothermally and without any requirement for external pumping devices. Two-phase heat transfer by a thermosyphon has the advantage of high enthalpy transport that includes the sensible heat of the liquid, the latent heat of vaporization, and vapor superheat. In contrast, single-phase forced convection transports only the sensible heat of the fluid. Additionally, vapor-phase velocities within a thermosyphon are much greater than single-phase liquid velocities within a forced convective loop. Thermosyphon performance can be limited by the sonic limit (choking) of vapor flow and/or by condensate entrainment. Proper thermosyphon requires analysis of both.

The interstitial gaps are an inherent presence in the reactor core because of tolerances in manufacturing the blocks and the inexact nature of their installation. Furthermore, the geometry of the graphite blocks changes over the lifetime of the reactor because of thermal expansion and irradiation damage. The occurrence of hot spots in the core and lower plenum and hot streaking in the lower plenum (regions of very hot gas flow) are affected by bypass flow. In the present study, three-dimensional computational fluid dynamic (CFD) calculations of a typical prismatic VHTR are conducted to better understand bypass flow phenomena and establish an evaluation method for the reactor core using the commercial CFD code FLUENT. Parametric calculations changing several factors in a one-twelfth sector of a fuel column are performed. The simulations show the impact of each factor on bypass flow and the resulting flow and temperature distributions in the prismatic core. Factors include inter-column gap-width, turbulence model, axial heat generation profile and geometry change from irradiation-induced shrinkage in the graphite block region. It is shown that bypass flow provides a significant cooling effect on the prismatic block and that the maximum fuel and coolant channel outlet temperatures increase with an increase in gap-width, especially when a peak radial factor is applied to the total heat generation rate. Also, the presence of bypass flow causes a large lateral temperature gradient in the block and also dramatically increases the variation in coolant channel outlet temperatures for a given block that may have repercussions on the structural integrity of the graphite, the neutronics and the potential for hot streaking and hot spots occurring in the lower plenum.

As with any fuel development program, the thermo-physical properties of the fuel as a function of temperature are extremely important and must be well characterized in order to effectively model and predict fuel behavior under normal and off-normal irradiation conditions. For the alloy system under investigation, the available thermo-physical property data is relatively inconsistent and often lacks appropriate explanation. Available literature on this alloy system comes mainly from studies done during the 1960s and 1970s, and often does not include sufficient information on fabrication history or conditions to draw conclusions for the current application. The current paper has investigated specific heat capacity, coefficient of linear thermal expansion, density, and thermal diffusivity that were then used to calculate alloy thermal conductivity as a function of temperature. The data obtained from this investigation was compared to available literature on similar U-Mo alloys, and in most cases are in good agreement.

Presently, multichannel and multielectrode data collections systems can collect large data sets in relatively short periods of time. Practitioners, however, often are unable to fully utilize these large data sets and the information they contain because of standard desktop-computer processing limitations. These limitations can be addressed by utilizing the storage and processing capabilities of parallel computing environments. We have developed a parallel distributed-memory forward and inverse modeling algorithm for analyzing resistivity and time-domain induced polarization (IP) data. The primary components of the parallel computations include distributed computation of the pole solutions in forward mode, distributed storage and computation of the Jacobian matrix in inverse mode, and parallel execution of the inverse equation solver. We have tested the corresponding parallel code in three efforts: (1) resistivity characterization of the Hanford 300 Area Integrated Field Research Challenge site in Hanford, Washington, U.S.A., (2) resistivity characterization of a volcanic island in the southern Tyrrhenian Sea in Italy, and (3) resistivity and IP monitoring of biostimulation at a Superfund site in Brandywine, Maryland, U.S.A. Inverse analysis of each of these data sets would be limited or impossible in a standard serial computing environment, which underscores the need for parallel high-performance computing to fully utilize the potential of electrical geophysical methods in hydrogeophysical applications.

To investigate the transport and fate of the (super 90) Sr through this 137-m-thick, heterogeneous, variably saturated subsurface, we conducted a two-dimensional numerical modeling using TOUGHREACT under different assumed scenarios (low permeability of an entire interbed or just its surface) for the formation of perched water whose presence reflects the unique characteristics of the geologic materials and stratification at the study site. The results showed that different mechanisms could lead to different flow geometries. The assumption of low permeability for the entire interbed led to the largest saturated zone area and the longest water travel time (55 vs. 43 or 44 yr in other scenarios) from the SBW leakage to the groundwater table. Simulated water travel time from different locations on the land surface to the groundwater aquifer varied from 80 yr. The results also indicated that different mechanisms may lead to differences in the peak and travel time of a small mobile fraction of Sr. The effective distribution coefficient and retardation factor for Sr (super 2+) would change more than an order of magnitude for the same material during the 200-yr simulation period because of large changes in the concentrations of Sr (super 2+) and competing ions. Understanding the migration rate of the mobile Sr (super 2+) is necessary for designing long-term monitoring programs to detect it.

Part 2: Analyses on the tritium behaviors in the VHTR/HTSE system AN - 753645469; 13138677 AB - Tritium behaviors in the very high temperature gas reactor (VHTR)/high temperature steam electrolysis (HTSE) system have been analyzed by the TPAC developed by Idaho National Laboratory (INL). The reference system design and conditions were based on the indirect parallel configuration between a VHTR and a HTSE. The analyses were based on the SOBOL method, a modern uncertainty and sensitivity analyses method using variance decomposition and Monte Carlo method. A total of 14 parameters have been taken into account associated with tritium sources, heat exchangers, purification systems, and temperatures. Two sensitivity indices (first order index and total index) were considered, and 15,360 samples were totally used for solution convergence. As a result, important parameters that affect tritium concentration in the hydrogen product have been identified and quantified with the rankings. Several guidelines and recommendations for reducing modeling uncertainties have been also provided throughout the discussions along with some useful ideas for mitigating tritium contaminations in the hydrogen product.

13076131 AB - When developing advanced nuclear energy systems, one needs to carefully consider the performance of the fuel in a particular reactor. For the case where a metallic fuel is used in a Sodium Fast Reactor (SFR), many different phenomena can affect the performance of the fuel, including fuel cladding chemical interaction (FCCI). During irradiation, a metallic fuel swells and eventually contacts the cladding, at which time FCCI can occur. During this process, interdiffusion occurs between the fuel, cladding, and fission products, which can result in the formation of interaction zones on the inner surface of the cladding that can become brittle or may contain relatively low-melting phases. The result of this process can be cracking and failure of the cladding. In-reactor and out-of-reactor testing has been conducted to improve the understanding of FCCI. This paper will discuss the results of different types of experiments that have been performed to improve the understanding of FCCI.

14237179 AB - High performance liquid chromatography and gas chromatography techniques are well documented and widely used for the detection of trace explosives from organic solvents. These techniques were modified to identify and quantify explosives extracted from various materials taken from people who had recently handled explosives. Documented techniques were modified to specifically detect and quantify trace levels of the military explosives, RDX, TNT, and PETN from denim, colored flannel, vinyl, and canvas extracted in methanol and filtered using no additional sample cleanup of the sample extract prior to analysis. The filtered methanol extracts were injected directly into several different column types and analyzed by high performance liquid chromatography using ultraviolet detection and/or gas chromatography using electron capture detection. This paper describes general screening methods that were used to determine the presence of explosives (RDX, TNT, and PETN) in unknown samples of denim, colored flannel, vinyl and canvas in addition to techniques that have been optimized for quantification of each explosive from the substrate extracts.

The reference plant design is driven by a high-temperature helium-cooled nuclear reactor coupled to a direct Brayton power cycle. The reference design reactor power is 600 MWt, with a primary system pressure of 7.0 MPa, and reactor inlet and outlet fluid temperatures of 540C and 900C, respectively. The electrolysis unit used to produce hydrogen includes 4,009,177 cells with a per-cell active area of 225 cm2. The optimized design for the reference hydrogen-production plant operates at a system pressure of 5.0 MPa, and utilizes an air-sweep system to remove the excess oxygen that has evolved on the anode (oxygen) side of the electrolyzer. The inlet air for the air-sweep system is compressed to the system operating pressure of 5.0 MPa in a four-stage compressor with intercooling. The alternating current to direct current conversion efficiency is 96%. The overall system thermal-to-hydrogen-production efficiency (based on the lower heating value of the produced hydrogen) is 47.1% at a hydrogen-production rate of 2.356 kg/s. This hydrogen-production efficiency is considerably higher than can be achieved using current low-temperature electrolysis techniques. An economic analysis of this plant was performed using the standardized hydrogen analysis methodology developed by the Department of Energy Hydrogen Program, and using realistic financial and cost estimating assumptions. The results of the economic analysis demonstrated that the HTE hydrogen-production plant driven by a high-temperature helium-cooled nuclear power plant can deliver hydrogen at a competitive cost. A cost of $3.23/kg of hydrogen was calculated assuming an internal rate of return of 10%. JF - Journal of Energy Resources Technology.

ER - TY - JOUR T1 - Comparison of natural convection flows under VHTR type conditions modeled by both the conservation and incompressible forms of the Navier-Stokes equations AN - 753751503; 13036315 AB - This paper illustrates a comparative study to analyze the physical differences between numerical simulations obtained with both the conservation and incompressible forms of the Navier-Stokes equations for natural convection flows in simple geometries. The purpose of this study is to quantify how the incompressible flow assumption (which is based upon constant density advection, divergence-free flow, and the Boussinesq gravitational body force approximation) differs from the conservation form (which only assumes that the fluid is a continuum) when solving flows driven by gravity acting upon density variations resulting from local temperature gradients. Driving this study is the common use of the incompressible flow assumption in fluid flow simulations for nuclear power applications in natural convection flows subjected to a high heat flux (large temperature differences). A series of simulations were conducted on two-dimensional, differentially heated rectangular geometries and modeled with both hydrodynamic formulations. From these simulations, the selected characterization parameters of maximum Nusselt number, average Nusselt number, and normalized pressure reduction were calculated. Comparisons of these parameters were made with available benchmark solutions for air with the ideal gas assumption at both low and high heat fluxes. Additionally, we generated specific force quantities and velocity and temperature distributions to provide a basis for further analysis. The simulations and analysis were then extended to include helium at the Very High Temperature gas-cooled Reactor (VHTR) normal operating conditions. Our results show that the consequences of incorporating the incompressible flow assumption in high heat flux situations may lead to unrepresentative results. The results question the use of the incompressible flow assumption for simulating fluid flow in an operating nuclear reactor, where large temperature variations are present.

14350217 AB - Air ingress has been identified as a potential threat for Very High Temperature gas-cooled Reactors (VHTR). Reactor components constructed of graphite will, at high temperatures, produce exothermic reactions in the presence of oxygen. The danger lies in the possibility of fuel element damage and core structural failure. Previous investigations of air ingress mechanisms have focused on thermal and molecular diffusion, density-driven stratified flow due to hydrodynamic instability, and natural convection. Not yet investigated is the possibility of a rapid flow reversal of helium coolant due to a Taylor (rarefaction) wave expansion after a hypothetical sudden Depressurized Loss of Forced Cooling (DLOFC) scenario in a VHTR. Conceivably, flow reversal of the helium coolant could entrain significant quantities of air into the reactor vessel. Our goal here is to simply demonstrate this natural phenomena of compressible flow that could possibly result in rapid air ingress into a VHTR. We start with a one-dimensional shock tube simulation to simply illustrate the development of a Taylor wave. The simulation is carried out far enough in time to allow the resulting reentrant flow to occur. Then, a simulation is performed of an idealized two-dimensional axisymmetric representation of the lower plenum of General Atomics GT-MHR subjected to a hypothetical catastrophic break of the hot duct. Results show the potential for significant and rapid air ingress into the reactor vessel in the case of a large break in the cooling system.

These techniques allow the system performance data and any relevant associated information to be used collectively to calculate the probabilities of various types of hypotheses that are formulated as part of reliability assurance activities. This paper proposes a methodology based on Bayesian hypothesis testing to determine the number of tests that would be required to demonstrate that a system-level reliability target is met with a specified probability level. Recognizing that full-scale testing of a complex system is often not practical, testing schemes are developed at the subsystem level to achieve the overall system reliability target. The approach uses network modeling techniques to transform the topology of the system into logic structures consisting of series and parallel subsystems. The paper addresses the consideration of cost in devising subsystem level test schemes. The developed techniques are demonstrated using several examples. All analyses are carried out using the Bayesian analysis tool WinBUGS, which uses Markov chain Monte Carlo simulation methods to carry out inference over the network.

Ammonia-oxidizing bacteria (AOB) and archaea (AOA) were present in all of the samples tested, with AOA amoA genes outnumbering AOB amoA genes in all of the samples. Following urea addition, nitrate levels rose and bacterial amoA copy numbers increased dramatically, suggesting that urea hydrolysis stimulated nitrification. Bacterial amoA diversity was limited to two Nitrosomonas phylotypes, whereas archaeal amoA analyses revealed 20 distinct operational taxonomic units, including several that were markedly different from all previously reported sequences. Results from this study demonstrate the likelihood of stimulating ammonia-oxidizing communities during field scale manipulation of groundwater conditions to promote urea hydrolysis.

2011-043528 AB - Progress towards the development of a better understanding of the formation of geological patterns in wet systems due to precipitation and dissolution is reviewed. Emphasis is placed on the formation of terraces, stalactites, stalagmites and other carbonate patterns due to precipitation from flowing supersaturated solutions and the formation of scallops by dissolution in undersaturated turbulent fluids. In addition, the formation of spherulites, dendrites and very large, essentially euhedral, crystals is discussed. In most cases, the formation of very similar patterns as a result of the freezing/melting of ice and the precipitation/dissolution of minerals strongly suggests that complexity associated with aqueous chemistry, interfacial chemistry and biological processes has only a secondary effect on these pattern formation processes.

15122061 AB - As part of the Department of Energy's Advanced Technology Development Program, lithium-ion cells of various sizes and chemistries are aged with periodic reference performance tests to ascertain degradation rates. The reference tests include a very slow discharge and charge based on a constant current equal to 1/25th of the rated capacity to elucidate the true electrochemical capacity of the cell. A differential analysis of these data helps to identify the individual kinetic and thermodynamic contributions of the anode and cathode. However, differential curves are very noisy, and previous smoothing methods included simple data reduction and moving averages. This paper introduces an alternative method of finding the differential voltage and differential capacity curves based on radial basis functions. The voltage profile is fit with a number of Gaussian curves, and the resulting model is differentiated. This approach also has the added advantage of assessing model uncertainty based on a bootstrap analysis. The radial basis function method was successfully applied to various lithium-ion chemistries tested under the Advanced Technology Development Program. The resulting differential capacity and differential voltage curves are generally smoother than the corresponding curves found by previous methods and also show little variance, indicating a good model fit. These results imply that the radial basis function technique is a more robust tool for assessing differential data.

Degradation mechanisms of chloronitromethane, bromonitromethane, and dichloronitromethane. AN - 733682820; 20055512 AB - Halonitromethanes (HNMs) are byproducts formed through ozonation and chlorine/ chloramine disinfection processes in drinking waters that contain dissolved organic matter and bromide ions. These species occur at low concentration but have been determined to have high cytotoxicity and mutagenicity and therefore may represent a human health hazard. In this study, we have investigated the chemistry involved in the mineralization of HNMs to nonhazardous inorganic products through the application of advanced oxidation and reduction processes. We have combined measured absolute reaction rate constants for the reactions of chloronitromethane, bromonitromethane, and dichloronitromethane with the hydroxyl radical and the hydrated electron with a kinetic computer model in an attempt to elucidate the reaction pathways of these HNMs. The results are compared to measurements of stable products resulting from steady-state (60)Co gamma-irradiations of the same compounds. The model predicted the decomposition of the parent compounds and ingrowth of chloride and bromide ions with excellent accuracy, but the prediction of the total nitrate ion concentration was slightly in error, reflecting the complexity of nitrogen oxide species reactions in irradiated solution.

This unique data set has been inverted in 3D by minimizing the L (sub 2) norm of the data misfit using a Gauss-Newton approach. The true 3D inversion was performed using parallel processing on an unstructured tetrahedral mesh containing 75,549 finite-element nodes and 398,208 elements to accurately model the topography of the volcanic edifice. The 3D tomogram shows a very conductive body (>0.1 S/m) comprised inside the Pietre Cotte crater with conductive volumes that are consistent with the position of temperature and CO (sub 2) anomalies at the ground surface. This conductive body is interpreted as the main hydrothermal body. It is overlaid by a resistive and cold cap in the bottom of the crater. The position of the conductive body is consistent with the deformation source responsible for the observed 1990-1996 deflation of the volcano associated with a decrease of hydrothermal activity.

Due to the similarities in the chemical properties of the trivalent actinides and lanthanides, this separation is difficult to accomplish. The introduction of soft donor groups, such as N or S, into similarly structured ligands increases the differentiation between An(III) and Ln(III) cation coordination. Partly because of limitations imposed by synthetic methodologies, previous studies of dithiophosphinic acid (DPAH) extractants has been restricted to a comparatively small number of symmetrical dialkyl and diaryl derivatives. Research efforts at the Idaho National Laboratory have resulted in the recent development of an innovative synthetic pathway yielding new regiospecific DPAH extractants. The synthesis improves DPAH designs that can address the issues concerning minor actinide separation efficiency and extractant stability. Several new symmetric and asymmetric DPAH extractants have been prepared. The use of these extractants for the separation of minor actinides from lanthanides will be discussed. In addition, the variation in the extent of Am(III) extraction by a related series of DPAH isomers will be presented.

This testing was performed using a non-radioactive feed surrogate and data were collected and analyzed to evaluate removal efficiencies of the lanthanides, mass transfer efficiency of the lanthanides in the extraction and strip sections of the flowsheet, and the temperature profile of the process solutions throughout the centrifugal contactor pilot plant. Results indicate >99.9% separation for all lanthanides and mass transfer efficiencies typically ranging from 85% to 100%. Energy input into the process under flowsheet conditions resulted in only a moderate temperature rise and did not appear to have a large effect on separations performance. The general process performance is also described.

The purpose of this program is to return Soviet or Russian supplied high enriched uranium (HEU) fuel currently stored at Russian designed research reactors throughout the world to Russia. To accommodate transport of the HEU spent nuclear fuel, a new large capacity transport/storage cask system was specially designed for handling and operations under the unique conditions for these research reactor facilities. This new cask system is named the SKODA VPVR/M cask. The design, licensing, testing and delivery of this new cask system are the results of a significant international cooperative effort by several countries and involved numerous private and governmental organisations. This paper contains the following sections: (i) introduction/background; (ii) VPVR/M cask description; (iii) ancillary equipment, (iv) cask licensing; (v) cask demonstration and operations; (vi) IAEA procurement, quality assurance inspections, fabrication, and delivery; and, (7) summary and conclusions.

We first inverted resistivity and induced polarization CWEI data sets for distributions of electrical resistivity and polarizability, from which the spatial complexity of the primary hydrogeologic units was reconstructed. Variations in the depth to the interface between the overlying coarse-grained, high-permeability Hanford Formation and the underlying finer-grained, less permeable Ringold Formation, an important contact that limits vertical migration of contaminants, were resolved along approximately 3 km of the river corridor centered on the 300 Area. Polarizability images were translated into lithologic images using established relationships between polarizability and surface area normalized to pore volume (S (sub por) ). The FO-DTS data recorded along 1.5 km of cable with a 1 m spatial resolution and 5 min sampling interval revealed subreaches showing (1) temperature anomalies (relatively warm in winter and cool in summer) and (2) a strong correlation between temperature and river stage (negative in winter and positive in summer), both indicative of reaches of enhanced surface water-groundwater exchange. The FO-DTS data sets confirm the hydrologic significance of the variability identified in the CWEI and reveal a pattern of highly focused exchange, concentrated at springs where the Hanford Formation is thickest. Our findings illustrate how the combination of CWEI and FO-DTS technologies can characterize surface water-groundwater exchange in a complex, coupled river-aquifer system.

The ratio of the daughter to parent atoms is used to estimate the date when Cs was purified prior to source encapsulation (an 'age' since purification). The isotopes were analyzed by inductively coupled plasma mass spectrometry (ICP-MS) after chemical separation. In addition, Ba was analyzed by isotope dilution ICP-MS (ID-ICP-MS). A detailed error analysis of the mass spectrometric work has been undertaken to identify areas of improvement, as well as quantifying the effect the errors have on the 'age' determined. This paper reports an uncertainty analysis to identifying areas of improvement and alternative techniques that may reduce the uncertainties. In particular, work on isotope dilution using ICP-MS for the 'age' determination of sealed sources is presented.

Characteristics such as 'age' since purification, actinide content, trace metal content and inter and intra source composition were determined. The 'age' since purification of the two sources was determined to be 25.0 and 25.4 years, respectively. The systematic uncertainties in the 'age' determination were c4% 2*s. The amount and isotopic composition of U and Pu varied substantially between the sub-samples of Source 2 (n = 8). This may be due to the physical means of sub-sampling or the way the source was manufactured. Source 1 was much more consistent in terms of content and isotopic composition (n = 3 sub-samples). The Be--Am ratio varied greatly between the two sources. Source 1 had an Am--Be ratio of 6.3 c 52% (1*s). Source 2 had an Am--Be ratio of 9.81 c 3.5% (1*s). In addition, the trace element content between the samples varied greatly. Significant differences were determined between Sources 1 and 2 for Sc, Sr, Y, Zr, Mo, Ba and W.

Relying on selective metal complexing agents, the radiation stability of these solvent extraction ligands will determine the efficiency and recycle lifetime of any solvent intended for use in this high-radiation environment. This paper reviews work at the Idaho National Laboratory regarding the radiation chemistry of nuclear solvent extraction ligands, with particular emphasis on the reactions of nitrogen-centered radicals.

The GPEC system employs compressed nitrogen to move liquid through the system, compared to gravity or pumped liquids that are typically used for separations. A commercially available Sr-ResinTM was used to perform the separation for the above mentioned analytes. A 1% acetic acid solution was determined to be the best extractant for Ba. A flow rate of 0.1 mL/min was determined to be optimal for the separation of Ba. Complete recovery of the Cs and Ba was achieved, within the systematic uncertainties of the experiments.

Geophysical data potentially can help fill this information gap because geophysical methods can survey large areas remotely and relatively inexpensively. However, geophysical data are difficult to incorporate into hydrogeologic parameter estimations primarily because of a lack of knowledge concerning the petrophysical relationships between hydrogeologic and geophysical parameters. A method can be used that allows time-lapse geophysical data to be incorporated directly into a hydrogeologic parameter estimation when a strong correlation exists between changes in geophysical and hydrogeologic properties. This approach bypasses the need for an explicit petrophysical transform by formulating the geophysical part of the hydrogeologic inversion in terms of a data-domain correlation operator. A synthetic electrical resistivity monitoring application is used to estimate the hydraulic conductivity distribution. Including time-lapse resistivity data to supplement sparse hydrologic data appears to improve greatly the resolution of hydraulic conductivity in this case. More generally, the formulation and results suggest that geophysical monitoring data can be incorporated effectively into a hydrogeologic parameter estimation using a data-domain correlation operator, assuming a strong correlation exists between changes in hydrogeologic and geophysical properties.

This renewed interest has led to questions regarding the capability and capacity of current US industries to support a renewal of nuclear power plant deployment. Key among the many questions currently being asked is what potential exists for the creation of new jobs as a result of developing and operating these new plants? Idaho National Laboratory and Bechtel Power Corporation collaborated to perform a Department of Energy-sponsored study that evaluated the potential for job creation in the United States should these new next generation nuclear power plants be built. The study focused primarily on providing an initial estimate of the numbers of new manufacturing jobs that could be created, including those that could be repatriated from overseas, resulting from the construction of these new reactors. In addition to the growth in the manufacturing sector, the study attempted to estimate the potential increase in construction trades necessary to accomplish the new construction.

a key to the active tectonics of Cascadia AN - 881451591; 2011-065662 AB - Surface velocities derived from GPS observations have allowed high resolution views of the active deformation and rotation of the Cascadia forearc and backarc as well as elastic strain accumulation. We present an update of the Pacific Northwest GPS velocity field presented earlier by McCaffrey et al. (Geophys. J. Int., 2007) and Payne et al. (Geology, 2008). The new velocity field combines new Scripps Orbit and Permanent Array Center (SOPAC) daily solutions for 1994-2009 for the Basin and Range Geodetic (BARGN), Eastern Basin and Range-Yellowstone (EBRY), Pacific Northwest Geodetic Array (PANGA), Plate Boundary Observatory (PBO), and Western Canada Deformation Array (WCDA) networks (http://sopac.ucsd.edu/processing/gamit) with our solutions using data from surveys conducted by Idaho National Laboratory, Massachusetts Institute of Technology, National Geodetic Survey, Geologic Survey of Canada, Rensselaer Polytechnic Institute, US Geological Survey, University of Washington, and others, 1991-2009. The new field reveals that the large-scale clockwise rotation seen in western Washington and Oregon also extends southward into southern Idaho and the Snake River plain as well as into the northern Basin and Range of Nevada. The axes of rotation generally fall near the Oregon-Washington-Idaho border. We will present interpretations of the active tectonics of the Cascadia margin from northern California to SW British Columbia, based on this new field. Interpretations of the Snake River plain region are presented by Payne et al. (this meeting).

Yet, surprisingly little is known about the lifecycle water impacts of energy and crop production, and very few U.S. research programs investigate how water resource limitations constrain our ability to produce energy and sustain our economy, environment, and quality of life. Thus, little is known about whether various plans for improving U.S. energy security while reducing greenhouse gas emissions are practical from a water resource perspective--or whether such plans would impact our capacity to adapt to unavoidable climate change. This paper begins to assess this issue by (i) evaluating how various water constraints impact energy decision making at both a systems and local/regional level; (ii) providing initial lifecycle water estimates for a selection of representative energy generating technologies; and (iii) demonstrating how these considerations impact energy decision making. We conclude with a discussion of the challenges that must be considered when doing lifecycle water evaluations, and a summary of key issues that lifecycle water calculations must address.

GSA produces consensus Position Papers on important policy issues developed by expert panels with society member input and adoption by the GSA Council. Additionally GSA encourages members to make geoscience input on specific pending policies at local, state, regional or national levels. In early 2009 GSA staff created the Policycomnet policy networking site at the request of and with the guidance of the Division of Geology and Society and the Geology and Public Policy Committee to encourage and facilitate greater member input to policy makers. GSA policy communication is founded on principles of successful science input to lay recipients established by social science research. Guidelines summarizing the principles are on the site. To be successful, communications must come from trusted sources, and be understood and believed in order to have a prospect of influencing the recipient's actions. Recipient credibility is enhanced by receiving consistent reinforcing messages from multiple trusted sources, information about previous successful policies dealing with similar circumstances and by personal contact to discuss issues by phone or in person with an advisor. A member can post a suggested message about a pending policy decision on Policycomnet and invite other members to help develop a successful communication process. This online dialog facilitates sorting out of important issues and then planning of consistent individual reinforcing messages to specific decision makers that can increase communication effectiveness. GSA Policycomnet is hosted by Wikidotcom technology at no cost to the society. Users must register and log in using a password and their email addresses. The host site does not transfer email addresses to other parties and does not provide unsolicited email to registrants. Users can invite colleagues to join.

To better understand how the Agassiz Glacier might respond to continuing climate change, we developed a 2-D model of the glacier, and tested the model's ability to accurately simulate changes in a glacier in response to climate changes of the past 100 years. The modeling approach computes net-annual mass balance of a glacial valley based on average monthly temperature, precipitation, and radiation balance along with numerous secondary parameters including the distribution of snow by avalanches. The calculated mass balance is combined with a 2-D glacier-flow model to simulate areal ice extent under specified climate conditions. Meteorological inputs to the model were derived from the PRISM model (http://www.prism.oregonstate.edu/) characterizing the mean climate for 1971-2000 of the area occupied by the Agassiz Glacier. These parameters were then modified to simulate the changes in temperature and precipitation according to a 100-year historical record from nearby Kalispell, Montana. Although modeled mass balance and ice extent under the 1971-2000 average nearly match observations of the Agassiz Glacier over this interval, the simulated glacier underestimates ice extent during the first half of the 20 (super th) century when driven by the record from Kalispell. This discrepancy is likely due to differences in the magnitude of climate change at high altitude compared to low altitude; high altitude climate changes may have been of significantly greater magnitude. This inference is supported by a comparison of high altitude (SNOTEL) and low-altitude records for the past twenty-five years. Model simulations of known changes of ice extent through the past 100 years provide a guide for inferring high altitude temperature change. By combining these results with improvements to high altitude records of climate change, we can set more precise limits on the sensitivity of mountain glaciers to decadal-scale climate change. This effort should aid in improving predictions of the response of the Agassiz Glacier to the changes in temperature and precipitation projected for upcoming decades.

Here we present data collection and simulation for assembling two- and three-dimensional property sets based on the spatial characteristics of low-volume pahoehoe basalts typical of the East Snake River Plain Aquifer in southeast Idaho. Two-point covariance statistics for fracture zones were elicited from field data collected on pahoehoe basalt exposures at the Box Canyon field site resulting in an anisotropic model of spatial correlation. The model variogram was then used for sequential indicator simulation to construct 100 equally probable property sets. These property sets were used to specify the model domain for supercritical carbon dioxide injection. Results indicate that the model domain based on two-point sequential indicator simulation provides a reasonable representation of fracture zone heterogeneity suitable for carbon injection modeling.

The northern and central segments of the three normal faults are seismically active, but their activity decreases southward toward the ESRP. Deformation in the ESRP is associated with infrequent small magnitude (M<2) microearthquakes and NW-trending volcanic rift zones that result from basalt dike intrusion since 6 to 4 Ma. GPS results from 1994-2009 indicate that the extension rate across the NW-trending normal faults is an order of magnitude faster than in the ESRP. A NE-trending zone of right-lateral shear, referred to as the Centennial Shear Zone (CSZ), is a geometric consequence of the differential strain rates. The inferred slip rate in the CSZ of 1-2 mm/yr suggests up to 2 km of lateral offset in a million years. Within the footwalls of the NW-trending normal faults, investigators have identified only NE-trending normal faults without observable strike-slip offsets. The most recent and larger fault offsets are associated with extension on the NW-trending normal faults (e.g., 1983 Ms 7.3 Borah Peak, Idaho earthquake). To test ideas of how right-lateral shear is accommodated, we use a block model and invert horizontal GPS velocities, earthquake slip vectors and fault slip rates for relative motions. We find that the data do not support either a transtension model (e.g., McKenzie and Jackson, 1986) in which the NW-trending normal fault blocks are pinned at their northwest and southeast ends and accommodate shear through oblique slip and clockwise rotation, or a "fan" model in which the blocks are pinned at their northwest ends only. The data are fit best by a model in which right-lateral shear is accommodated along NE-trending faults at the northwest and southeast ends of the normal faults with minor components of oblique slip on the normal faults. This model requires very little clockwise rotation in the footwalls and is supported by paleomagnetic data, which suggest a clockwise rotation rate <1 degree/m.y. in the footwalls of two of three normal faults.

Results were compared to the microstructure of the as-fabricated dispersion fuel to identify changes that occurred during irradiation. The layer that formed on the surface of the fuel U-7Mo particles during fuel plate fabrication exhibits stable irradiation performance as a result of the [not, vert, similar]0.88 wt% Si present in the fuel meat matrix. During irradiation, the pre-formed interaction layer changed very little in thickness and composition. The overall irradiation performance of the fuel plate to moderate power and burnup was considered excellent.

To explore whether the resistance of HT9 to void swelling is maintained under more realistic operating conditions, the radiation-induced microstructure of an HT9 ferritic/martensitic hexagonal duct was examined following a six-year irradiation of a fuel assembly in the Fast Flux Test Reactor Facility (FFTF). The calculated irradiation exposure and average operating temperature of the duct at the location examined were [not, vert, similar]155 dpa at [not, vert, similar]443 degree C. It was found that dislocation networks were predominantly composed of (a/2) Burgers vectors. Surprisingly, for such a large irradiation dose, type a interstitial loops were observed. Additionally, a high density of precipitation occurred. These two microstructural characteristics may have contributed to the rather low swelling level of 0.3%.

To evaluate the potential benefits of nuclear-driven hydrogen production, the UniSim process analysis software was used to evaluate different reactor concepts coupled to a reference HTE process design concept. The reference HTE concept included an intermediate heat exchanger and intermediate helium loop to separate the reactor primary system from the HTE process loops and additional heat exchangers to transfer reactor heat from the intermediate loop to the HTE process loops. The two process loops consisted of the water/steam loop feeding the cathode side of a HTE electrolysis stack, and the sweep gas loop used to remove oxygen from the anode side. The UniSim model of the process loops included pumps to circulate the working fluids and heat exchangers to recover heat from the oxygen and hydrogen product streams to improve the overall hydrogen production efficiencies. The reference HTE process loop model was coupled to separate UniSim models developed for three different advanced reactor concepts (a high-temperature helium cooled reactor concept and two different supercritical CO sub(2) reactor concepts). Sensitivity studies were then performed with the objective of evaluating the affect of reactor outlet temperature on the power cycle efficiency and overall hydrogen production efficiency of the integrated plant design for each of the reactor power cycles. The results of these sensitivity studies showed that overall power cycle and hydrogen production efficiencies increased with reactor outlet temperature, but the power cycles producing the highest efficiencies varied depending on the temperature range considered.

Part II: Ceramic fuels AN - 918037975; 13404993 AB - This paper is Part II of a review focusing on the United States experience with oxide, carbide, and nitride fast reactor fuel fabrication. Over 60 years of research in fuel fabrication by government, national laboratories, industry, and academia has culminated in a foundation of research and resulted in significant improvements to the technologies employed to fabricate these fuel types. This part of the review documents the current state of fuel fabrication technologies in the United States for each of these fuel types, some of the challenges faced by previous researchers, and how these were overcome. Knowledge gained from reviewing previous investigations will aid both researchers and policy makers in forming future decisions relating to nuclear fuel fabrication technologies.

Although the complex geometries of fracture apertures, fracture networks, and pore spaces may make it difficult to accurately predict fluid flow in saturated (single-phase) subsurface systems, well-developed methods are available. The simulation of multiphase fluid flow in the subsurface is much more challenging because of the large density and/or viscosity ratios found in important applications (water/air in the vadose zone; water/oil, water/gas, gas/oil, and water/oil/gas in hydrocarbon reservoirs; water/air/nonaqueous phase liquids (nonaqueous phase liquids/dense nonaqueous phase liquids) in contaminated vadose zone systems; and gas/molten rock in volcanic systems, for example). In addition, the complex behavior of fluid-fluid-solid contact lines and their impact on dynamic contact angles must also be taken into account and coupled with the fluid flow. Here we review the methods that are currently being used to simulate pore-scale multiphase fluid flow and reactive transport in fractured and porous media. After the introduction, the review begins with an overview of the fundamental physics of multiphase fluids flow followed by a more detailed discussion of the complex dynamic behavior of contact lines and contact angles, an important barrier to accurate pore-scale modeling and simulation. The main part of the review focuses on five different approaches: pore network models, lattice gas and lattice Boltzmann methods, Monte Carlo methods, particle methods (molecular dynamics, dissipative particle dynamics, and smoothed particle hydrodynamics), and traditional grid-based computational fluid dynamics coupled with interface tracking and a contact angle model. Finally, the review closes with a discussion of future trends and challenges.

2010-025578 AB - The purposes of this study were to (i) document chemical and mineralogical compositions in two naturally acidic drainages over a 1 m soil profile, (ii) document organic and inorganic signatures representative of past chemical or biological processes in the soils, and (iii) determine whether mineralogical and chemical differences are a consequence of differences in original composition, depositional conditions, or diagenesis. Two sites were studied: Paymaster Creek in the Heddleston Mining District near Lincoln, Montana and the New World Mining District near Cooke City, Montana. The oldest deposits at both naturally acidic sites pre-date human mining activity by several thousand years, although there is recent human activity at both sites. Both sites have streams with high dissolved Fe and moderately low pH and actively accumulate schwertmannite on streambeds. Soil deposits away from the streambed at Paymaster Creek contained goethite with adsorbed sulfate, but no schwertmannite, suggesting either that the original conditions precluded schwertmannite precipitation or that diagenesis occurred rapidly converting the schwertmannite to goethite. The New World Mining District site showed the expected profile, which is a gradual transition from schwertmannite- and goethite-bearing soils to goethite-only soils. Concentrations of Cr, As and other trace elements shown to retard diagenesis were higher at the New World site than at the Paymaster site.

Renewed interest in the behavior of MA's during fuel irradiation has prompted further examination of existing X501 data, and generation of new data where needed in support of the US waste transmutation effort. The X501 experiment is one of the few MA-bearing fuel irradiation tests conducted worldwide and knowledge can be gained by understanding the changes in fuel behavior due to addition of MA's. Of primary interest are the affect of the MA's on fuel-cladding-chemical-interaction, and the redistribution behavior of americium. The quantity of helium gas release from the fuel and any effects of helium on fuel performance are also of interest. This paper provides a summary of the X501 fabrication, characterization, irradiation, and postirradiation examination.

This paper presents an evaluation of metallic alloy fuels. Early US fast reactor developers originally favored metal alloy fuel due to its high fissile density and compatibility with sodium. The goal of fast reactor fuel development programs is to develop and qualify a nuclear fuel system that performs all of the functions of a conventional fast spectrum nuclear fuel while destroying recycled actinides. This will provide a mechanism for closure of the nuclear fuel cycle. Metal fuels are candidates for this application, based on documented performance of metallic fast reactor fuels and the early results of tests currently being conducted in US and international transmutation fuel development programs.

This re-consideration follows with intense developmental programs for both fuel and reactor design. One of the two leading candidates for next generation fast reactor fuel is metal alloys, resulting primarily from the successes achieved in the 1960s to early 1990s with both the experimental breeding reactor-II and the fast flux test facility. The goal of the current program is to develop and qualify a nuclear fuel system that performs all of the functions of a conventional, fast-spectrum nuclear fuel while destroying recycled actinides, thereby closing the nuclear fuel cycle. In order to meet this goal, the program must develop efficient and safe fuel fabrication processes designed for remote operation. This paper provides an overview of advanced casting processes investigated in the past, and the development of a gaseous diffusion calculation that demonstrates how straightforward process parameter modification can mitigate the loss of volatile minor actinides in the metal alloy melt.

This paper examines a subset of phenomena that are important in the development of an analysis capability for fuel performance calculations, focusing on thermomechanics and diffusion within UO sub(2) fuel pellets. In this study, correlations from the literature are used for thermal conductivity, specific heat, and oxygen diffusion. This study develops a three dimensional thermomechanical model fully-coupled to an oxygen diffusion model. Both steady state and transient results are examined to compare this three dimensional model with the literature. Further, this equation system is solved in a parallel, fully-coupled, fully- implicit manner using a preconditioned Jacobian-free Newton Krylov method. Numerical results are presented to explore the efficacy of this approach for examining selected fuel performance problems. INL's BISON fuels performance code is used to perform this analysis.

10099336 AB - The Tritium Plasma Experiment (TPE) has been used to investigate deuterium fuel retention behavior in tungsten and molybdenum-materials utilized for plasma-facing surfaces in some existing tokamak plasma devices and under consideration for future devices. Although several studies have been performed over the past several years on these metals, many issues remain unresolved, including for example blister formation mechanisms and correlation to surface conditions. In this study, we expose several metal samples to deuterium ion fluences up to 10 super(26) ions/m super(2) and measure retention behavior with thermal desorption spectroscopy. Fractional retention of up to 2.0 x 10 super(-5) is found for W at 600 K, and Mo similarly retains deuterium at a fraction of 1.5 x 10 super(-5) at 600 K. Blistering was found for W samples exposed at temperatures above 453 K, whereas blistering was not observed for Mo samples at any experiment temperature.

Advances in R&D for advanced SFR fuel and structural materials provide key long-term opportunities to improve SFR economics. In addition, other new opportunities are emerging to further improve SFR economics. This paper provides an overview on potential ideas from the perspective of thermal hydraulics to improve SFR economics. These include: (1) a new hybrid loop- pool reactor design to further optimize economics, safety, and reliability of SFRs with more flexibility, (2) a multiple-reheat and intercooling helium Brayton cycle to improve plant thermal efficiency and to reduce safety related overnight and operation costs, and (3) modern multi-physics thermal analysis methods to reduce analysis uncertainties and associated requirements for over-conservatism in reactor design. This paper reviews advances in all three areas and their potential beneficial impacts on SFR economics.

Experience with metal fuel fabrication in the United States is extensive, including over 60 years of research conducted by the government, national laboratories, industry, and academia. This experience has culminated in a considerable amount of research that resulted in significant improvements to the technologies employed to fabricate metallic fast reactor fuel. This part of the review documents the current state of fuel fabrication technologies for metallic fuels, some of the challenges faced by previous researchers, and how these were overcome. Knowledge gained from reviewing previous investigations will aid both researchers and policy makers in forming future decisions relating to nuclear fuel fabrication technologies.

The facility is designed to provide radiation shielding for deuterium-tritium (DT) fusion (14.1 MeV) neutron generators (2x10[super]8 n/s), deuterium-deuterium (DD) fusion (2.5 MeV) neutron generators (1x10[super]7 n/s), and [super]252Cf spontaneous fission neutron sources (6.96x10[super]7 n/s, 30 [micro]g). Shielding at the laboratory is comprised of modular concrete shield blocks 0.76 m thick with tongue-in-groove features to prevent radiation streaming, arranged into one small and one large test vault. The larger vault is designed to allow operation of the DT generator and has walls 3.8 m tall, an entrance maze, and a fully integrated electrical interlock system; the smaller test vault is designed for [super]252Cf and DD neutron sources and has walls 1.9 m tall and a simple entrance maze. Both analytical calculations and numerical simulations were used in the design process for the building to assess the performance of the shielding walls and to ensure external dose rates are within required facility limits. Dose rate contour plots have been generated for the facility to visualize the effectiveness of the shield walls and entrance mazes and to illustrate the spatial profile of the radiation dose field above the facility and the effects of skyshine around the vaults.

The reactor subunits are to be emplaced directly into the lunar regolith, utilizing the regolith not just for shielding but also as the reflector material to increase the neutron economy of the system. While a single subunit cannot achieve criticality by itself, coordinated placement of additional subunits will provide a critical reactor system for lunar surface power generation. A lunar regolith clustered-reactor system promotes reliability, safety, and ease of manufacture and testing at the cost of a slight increase in launch mass per rated power level and an overall reduction in neutron economy when compared to a single-reactor system. Additional subunits may be launched with future missions to increase the cluster size and power according to desired lunar-base power demand and lifetime. The results address the potential uncertainties associated with the lunar regolith material and emplacement of the subunit systems. Physical distance between subunits within the clustered emplacement exhibits the most significant feedback regarding changes in overall system reactivity. Narrow, deep holes will be the most effective in reducing axial neutron leakage from the core. The variation in iron concentration in the lunar regolith can directly influence the overall system reactivity, although its effects are less than the more dominant factors of subunit emplacement.

The purpose of this model is to investigate hydrogen production from beryllium dust layers on hot surfaces inside a fusion reactor vacuum vessel (VV) during in-vessel loss-of-cooling accidents (LOCAs). This beryllium dust oxidation model accounts for the diffusion of steam into a beryllium dust layer, the oxidation of the dust particles inside this layer based on the beryllium-steam oxidation equations developed at the INL, and the effective thermal conductivity of this beryllium dust layer. This paper details this oxidation model and presents the results of the application of this model to a wet bypass accident scenario in the ITER device.

The change of lattice constant evaluated using HOLZ patterns is not observed. In comparison to Kr ion irradiation at 800 C to 10 dpa from the previous studies, the proton irradiated ZrC and ZrN at 1.8 dpa show less irradiation damage to the lattice structure. The proton irradiated ZrC exhibits faulted loops which are not observed in the Kr ion irradiated sample. ZrN shows the least microstructural change from proton irradiation. The microstructure of 6H-SiC irradiated to 0.71 dpa consists of black dot defects at high density.

2011-011016 AB - Calcium carbonate is a secondary mineral precipitate influencing zero valent iron (ZVI) barrier reactivity and hydraulic performance. We conducted column experiments to investigate electrical signatures resulting from concurrent CaCO (sub 3) and iron oxides precipitation under simulated field geochemical conditions. We identified CaCO (sub 3) as a major mineral phase throughout the columns, with magnetite present primarily close to the influent based on XRD analysis. Electrical measurements revealed decreases in conductivity and polarization of both columns, suggesting that electrically insulating CaCO (sub 3) dominates the electrical response despite the presence of electrically conductive iron oxides. SEM/EDX imaging suggests that the electrical signal reflects the geometrical arrangement of the mineral phases. CaCO (sub 3) forms insulating films on ZVI/magnetite surfaces, restricting charge transfer between the pore electrolyte and ZVI particles, as well as across interconnected ZVI particles. As surface reactivity also depends on the ability of the surface to engage in redox reactions via charge transfer, electrical measurements may provide a minimally invasive technology for monitoring reactivity loss due to CaCO (sub 3) precipitation. Comparison between laboratory and field data shows consistent changes in electrical signatures due to iron corrosion and secondary mineral precipitation.

These liabilities, coupled with surging global demand for oil, have reignited interest in developing the U.S.'s domestic oil shale resources located in the Piceance and Uinta Basins of Utah, Colorado, and Wyoming. Developing these resources could significantly reduce U.S. oil imports, while improving the domestic economy and creating high-value jobs in areas that have few other options for economic development. However, oil shale development would impact relatively pristine lands and further stress the region's limited water resources. If these oil shale resources were developed using technologies tested and partially deployed in the 1970's and 1980's; then production of 1 million barrels per day of oil ( approximately 10% of current U.S. imports) would require approximately 0.1-0.35 million acre-feet per year of water. This equates to approximately 2-5% of the Upper Basin water allocations in the Colorado River Compact; and would require the construction of extensive infrastructure to manage surface water. However, this burden can be greatly reduced through adoption of new technologies and innovative water planning. One intriguing option is to use utilize "unconventional water", such as deep saline aquifers and produced water from oil and gas wells for oil shale development-thereby reducing the burden on surface water resources and providing for more environmentally benign disposal of current wastewater effluent. This paper will investigate new strategies for water management and enumerate the technological and policy challenges that must be overcome to enable innovative water planning and use.

It helps us to better understand our relation with the world around us; and often leads people who consider themselves to be "geoscientifically aware" to become interested in public policy. GSA supports and encourages these outreach activities through multiple initiatives; with one of the most important being the development of position statements to encourage and support member engagement in public policy initiatives. These 1-2 page documents, developed through a "slow, rigorous, and sometimes painful" process, provide a consensus view of the GSA membership on public policy issues that involve the geosciences. They provide key message points, and supporting information, for geoscientists to use when communicating with decision makers and local/regional stakeholder groups. They also provide a "3rd page" that provides suggestions for how GSA members can beneficially impact public policy in a given area. While valuable, these statements are not effective unless GSA members employ them in an effective manner. To be effective, a policy communication must be understood, be believed, and motivate people to take action. Unfortunately, geoscientists are often misunderstood, not convincing when we rely heavily on technical data to make a point, and usually have not been taught how to motivate people to take action. This presentation will provide a primer on GSA position statements, and suggest ways to use these statements to impact public policy--while avoiding common mistakes and abuses.

To assess the potential for endoxylanase activity at low water contents, endoxylanase activity was tested using a refined wheat arabinoxylan substrate and three commercial endoxylanases over the water activity range 0.21-1.0, corresponding to water contents of 5% to >60% (dry basis). Homogeneously mixed dry samples were prepared at a fixed enzyme to substrate ratio and incubated in chambers at a variety of fixed water activities. Replicates were sacrificed periodically, and endoxylanase activity was quantified as an increase in reducing sugar relative to desiccant-stored controls. Endoxylanase activity was observed at water activities over 0.91 in all enzyme preparations in less than 4days and at a water activity of 0.59 in less than 1week in two preparations. Endoxylanase activity after storage was confirmed for selected desiccant-stored controls by incubation at 100% relative humidity. Water content to water activity relationships were determined for three lignocellulosic substrates, and results indicate that two endoxylanase preparations retained limited activity as low as 7% to 13% water content (dry basis), which is well within the range of water contents representative of dry biomass storage.

We propose an inversion of the self-potential signals that accounts for the heterogeneous nature of the aquifer and a relationship between the electrical resistivity and the streaming current coupling coefficient. We recast the inversion of the self-potential data into a Bayesian framework. Synthetic tests are performed showing the advantage in using self-potential signals in addition to in situ measurements of the potentiometric levels to reconstruct the shape of the water table. This methodology is applied to a new data set from a series of coordinated hydraulic tomography, self-potential, and electrical resistivity tomography experiments performed at the Boise Hydrogeophysical Research Site, Idaho. In particular, we examine one of the dipole hydraulic tests and its reciprocal to show the sensitivity of the self-potential signals to variations of the potentiometric levels under steady-state conditions. However, because of the high pumping rate, the response was also influenced by the Reynolds number, especially near the pumping well for a given test. Ground water flow in the inertial laminar flow regime is responsible for nonlinearity that is not yet accounted for in self-potential tomography. Numerical modeling addresses the sensitivity of the self-potential response to this problem.

These data include valid alarms, unwanted or false alarms, ambulance calls, and hazardous material cleanup calls. Of special interest are false alarms, which are not only a nuisance to facility productivity but also are detrimental to public and facility safety. Of the fire calls listed here, over half were from false alarms. The results given are compared with National Fire Protection Association data. The data presented can serve as exemplar data for future facilities and can be compared with other operating facilities' experiences.

For future advanced nuclear systems, minor actinides (MA) are viewed more as a resource to be recycled, and transmuted to less hazardous and possibly more useful forms, rather than simply disposed of as a waste stream in an expensive repository facility. As a result, MAs play a much larger part in the design of advanced systems and fuel cycles, not only as additional sources of useful energy, but also as direct contributors to the reactivity control of the systems into which they are incorporated. In the study, a typical boiling water reactor (BWR) fuel unit lattice cell model with UO2 fuel pins will be used to investigate the effectiveness of minor actinide reduction approach (MARA) for enhancing proliferation resistance and improving the fuel cycle performance in the intermediate-term goal for future nuclear energy systems. To account for the water coolant density variation from the bottom (0.76 g/cm3) to the top (0.35 g/cm3) of the core, the axial coolant channel and fuel pin were divided to 24 nodes. The MA transmutation characteristics at different elevations were compared and their impact on neutronics criticality discussed. The concept of MARA, which involves the use of transuranic nuclides (237Np and/or 241Am), significantly increases the 238Pu/Pu ratio for proliferation resistance, as well as serves as a burnable absorber to hold-down the initial excess reactivity. It is believed that MARA can play an important role in atoms for peace and the intermediate-term of nuclear energy reconnaissance.

9302895 AB - Markov chain Monte Carlo (MCMC) approaches to sampling directly from the joint posterior distribution of aleatory model parameters have led to tremendous advances in Bayesian inference capability in a wide variety of fields, including probabilistic risk analysis. The advent of freely available software coupled with inexpensive computing power has catalyzed this advance. This paper examines where the risk assessment community is with respect to implementing modern computational-based Bayesian approaches to inference.

This study was performed to unequivocally answer this critique by addressing the potential for biofilm formation, the precursor to microbial-influenced corrosion, in radiation fields representative of spent nuclear fuel storage environments. This study involved the formation of a microbial biofilm on irradiated spent nuclear fuel cladding within a hot cell environment. This was accomplished by introducing 22 species of bacteria, in nutrient-rich media, to test vessels containing irradiated cladding sections and that was then surrounded by radioactive source material. The overall dose rate exceeded 2 Gy/h gamma/beta radiation with the total dose received by some of the bacteria reaching 5 X 103 Gy. This study provides evidence for the formation of biofilms on spent-fuel materials, and the implication of microbial influenced corrosion in the storage and permanent deposition of spent nuclear fuel in repository environments.

2010-012107 AB - Unmineable coalbeds are potentially large storage reservoirs for the sequestration of anthropogenic CO (sub 2) and offer the benefit of enhanced methane production, which can offset some of the costs associated with CO (sub 2) sequestration. The objective of this paper is to study the economic feasibility of CO (sub 2) sequestration in unmineable coal seams in the Powder River Basin of Wyoming. Economic analyses of CO (sub 2) injection options are compared. Results show that injecting flue gas to recover methane from CBM fields is marginally economical; however, this method will not significantly contribute to the need to sequester large quantities of CO (sub 2) . Separating CO (sub 2) from flue gas and injecting it into the unmineable coal zones of the Powder River Basin seam is currently uneconomical, but can effectively sequester over 86,000 tons (78,200 Mg) of CO (sub 2) per acre while recovering methane to offset costs. The cost to separate CO (sub 2) from flue gas was identified as the major cost driver associated with CO (sub 2) sequestration in unmineable coal seams. Improvements in separations technology alone are unlikely to drive costs low enough for CO (sub 2) sequestration in unmineable coal seams in the Powder River Basin to become economically viable. Breakthroughs in separations technology could aid the economics, but in the Powder River Basin they cannot achieve the necessary cost reductions for breakeven economics without incentives.

Crustal deformation in the NBR results from extension overprinted by bimodal volcanism in the SRP associated with the Yellowstone Hotspot. The SRP is a seismically quiet, low-relief physiographic feature that extends from eastern Oregon through southern Idaho and into northwestern Wyoming, USA. The NBR surrounds the SRP and is distinguished by its higher elevations, higher rates of seismicity, and active normal faulting. From 2006 to 2008, we reoccupied 110 survey-mode GPS sites in the SRP and NBR. The new regional velocity field includes these data merged with GPS phase data collected previously throughout the Pacific Northwest. Velocity gradients perpendicular to the directions of the velocities reveal that the SRP and NBR are part of the regional-scale clockwise rotation observed over the Pacific Northwest. The SRP is extending at a rate that is an order of magnitude lower than the NBR, explaining its low seismicity. Between these two regions we identify a NE-trending zone of right-lateral shear. We put together block regions based on GPS velocities, seismicity, and geology and invert simultaneously for angular velocities of the blocks, locking on faults between blocks, and horizontal strain rate tensors within blocks. Most of the velocity gradients are due to rotation with smaller components due to strain rates. The SRP and eastern Oregon rotate clockwise with a common angular velocity. Such large-scale regional rotations of the crust require that stresses be transmitted horizontally for long distances through the lithosphere and are probably not reflecting circular flow about a vertical axis in the mantle.

For example, one-third of all contaminated Department of Defense (DoD) sites have identified bioremediation or enhanced bioremediation, where amendments are used to stimulate microbial activity, as the primary remedial strategy. One of the main challenges associated with enhanced bioremediation is the validation of amendment delivery and remedial performance. Sampling methods are expensive and only provide point information; hence new tools are needed to enable more cost effective and reliable interpretation of amendment distribution and delivery. Time-lapse electrical resistivity tomography (ERT) is a proven method of providing non-invasive, volumetric information about the distribution of bulk subsurface electrical conductivity (1/resistivity) in space and time. In general, amendments have a different fluid conductivity than the ambient ground-water conductivity. In amendment-based remedial applications, temporal variations in bulk conductivity can be caused by amendment migration, amendment degradation, and/or amendment-driven biogeochemical activity. By imaging changes in bulk conductivity, time-lapse ERT has the potential to provide relevant information concerning spatial and temporal amendment behavior. We have developed and implemented an ERT-based approach for monitoring amendment behavior [Hydrogeophysical Performance Monitoring System (HPMS)], which is currently deployed at the former Brandywine Defense Reutilization Marking Office (DRMO), a DoD Superfund site now managed by Andrews Air Force Base, Brandywine, Maryland. At the core of this approach is a method to estimate changes in fluid conductivity from changes in bulk conductivity while accounting for spatial variability in both tomographic resolution and petrophysical calibration. The goals of our work are to (1) demonstrate the HPMS, and (2) provide site-specific insight into amendment behavior. Here, we describe the HPMS system and its implementation, and we discuss the associated resistivity inverse methodology and the results obtained to date from this system.

The equation is applicable to confinement pressure schemes commonly used during the collection of permeability data in the laboratory. The model is derived for cubic geometry under biaxial or hydrostatic confining pressures. The model is designed to handle changes in permeability caused by adsorption and desorption of gases onto and from the matrix blocks in fractured media. The model equations can be used to calculate permeability changes caused by the production of methane (CH (sub 4) ) from coal as well as the injection of gases, such as carbon dioxide, for sequestration in coal. Sensitivity analysis of the model found that each of the input variables can have a significant impact on the outcome of the permeability forecast as a function of changing pore pressure; thus, accurate input data are essential. The permeability model also can be used as a tool to determine input parameters for field simulations by curve fitting laboratory-generated permeability data. The new model is compared to two other widely used coal-permeability models using a hypothetical coal with average properties.

We estimated horizontal velocities for 132 stations within the Snake River Plain and the surrounding Basin and Range from GPS phase data collected from 1994 to 2007. These velocities show regional-scale clockwise rotation suggestive of driving forces beyond those associated with the Yellowstone hotspot. Within the western Centennial tectonic belt, the GPS measurements indicate that the Basin and Range is extending at a rate an order of magnitude greater than the Snake River Plain, which explains its low seismicity. Between these two regions, we discern the "Centennial shear zone," a NE-trending zone of right-lateral shear with estimated slip rates that increase northeastward from 0.9+ or -0.3 mm/yr in the SW to 1.7+ or -0.2 mm/yr in NE. We interpret the new GPS velocities to indicate: (1) right-lateral shear may be accommodated by strike-slip earthquakes on NE-trending faults in the Centennial shear zone; (2) three Basin and Range faults (Lost River, Lemhi, and Beaverhead) terminate at the Snake River Plain margin; and (3) extension in the Snake River Plain occurs at a much lower rate than the rate of normal faulting in the western Centennial tectonic belt.

Evolving from mainframe-based software, the current state-of-the-practice has led to the creation of the SAPHIRE software. Currently, agencies such as the Nuclear Regulatory Commission, the National Aeronautics and Aerospace Agency, the Department of Energy, and the Department of Defense use version 7 of the SAPHIRE software for many of their risk-informed activities. In order to better understand and appreciate the power of software as part of risk- informed applications, we need to recall that our current analysis methods and solution methods have built upon pioneering work done 30-40 years ago. We contrast this work with the current capabilities in the SAPHIRE analysis package. As part of this discussion, we provide information for both the typical features and special analysis capabilities, which are available. We also present the application and results typically found with state-of-the- practice PRRA models. By providing both a high-level and detailed look at the SAPHIRE software, we give a snapshot in time for the current use of software tools in a risk-informed decision arena.

The Idaho National Laboratory (INL) is part of the largest sagebrush steppe ecosystem on the continent. Scientists at the INL and the University of Idaho have integrated existing field and remotely-sensed data with geographic information systems technology to analyze how recent fires on the INL have influenced the current distribution of terrestrial vegetation. Three different vegetation mapping and classification systems were used to evaluate the changes in vegetation due to fires between 1994 and 2003. Twenty-four percent of the sagebrush steppe community on the INL was altered by fire, mostly over a seven year period. There were notable differences between methods, especially for juniper and grasslands. One method stood out in representing the landscape because it includes playa/bare ground/disturbed area and lava as vegetation categories. This study found that assessing existing data sets is useful for quantifying fire impacts and should be helpful in future fire and land use planning. It also demonstrated how different mapping and classification methods can influence the outcome from fire impact assessments. Adapted from the source document.

Much of the methane in hydrates is biogenic, so models that predict the presence and distribution of hydrates require accurate rates of in situ methanogenesis. We estimated the in situ methanogenesis rates in Hydrate Ridge (HR) sediments by coupling experimentally derived minimal rates of methanogenesis to methanogen biomass determinations for discrete locations in the sediment column. When starved in a biomass recycle reactor, Methanoculleus submarinus produced ca. 0.017 fmol methane/cell/day. Quantitative PCR (QPCR) directed at the methyl coenzyme M reductase subunit A gene (mcrA) indicated that 75% of the HR sediments analyzed contained <1,000 methanogens/g. The highest numbers of methanogens were found mostly from sediments <10 m below seafloor. By considering methanogenesis rates for starved methanogens (adjusted to account for in situ temperatures) and the numbers of methanogens at selected depths, we derived an upper estimate of <4.25 fmol methane produced/g sediment/day for the samples with fewer methanogens than the QPCR method could detect. The actual rates could vary depending on the real number of methanogens and various seafloor parameters that influence microbial activity. However, our calculated rate is lower than rates previously reported for such sediments and close to the rate derived using geochemical modeling of the sediments. These data will help to improve models that predict microbial gas generation in marine sediments and determine the potential influence of this source of methane on the global carbon cycle.

8551019 AB - Because of the impact that melt relocation and vessel failure have on subsequent progression and associated consequences of a light water reactor (LWR) accident, it is important to accurately predict the heat-up and relocation of materials within the reactor vessel and heat transfer to and from the reactor vessel. Accurate predictions of such heat transfer phenomena require high temperature thermal properties. However, a review of vessel and structural steel material properties in severe accident analysis codes reveals that the required high temperature material properties are extrapolated with little, if any, data above 700 DGC. To reduce uncertainties in predictions relying upon this extrapolated high temperature data, new thermal expansion data were obtained using pushrod dilatometry techniques for two steels used in LWR vessels: SA 533 Grade B, Class 1 (SA533B1) low alloy steel, which is used to fabricate most US LWR reactor vessels; and Type 304 stainless steel (SS304), which is used in LWR vessel piping, penetration tubes, and internal structures. This paper summarizes the new data and compares it to existing, lower temperature data in the literature.

The phenomenon is often attributed to the need to supplement animal diets with minerals available in the soil at mineral lick locations. Sodium is the mineral most frequently cited as being the specific component sought, although this has not been found universally. In this study area, bighorn sheep left normal summer-range to make bimonthly 26-km, 2,000-m-elevation round-trip migrations, the apparent purpose of which was to visit mineral licks on normal winter-range. Lick soil and normal summer-range soil were sampled for their available mineral content and summer-range forage was sampled for total mineral content, and comparisons were made to determine the specific components sought at the lick by bighorn sheep consuming soil. It was concluded that bighorn sheep were attracted to the lick by a desire for sodium but that geophagia also supplemented a diet deficient in the trace element selenium. Where sheep are denied access to licks, populations may be limited by mineral deficiency.

S. Department of Energy's Idaho National Laboratory. During a transfer operation in November 1972, 70.4 m (super 3) of acidic, high ionic strength liquid containing 15,900 Ci of (super 90) Sr was released over five days into alluvial gravels 137 m above the Snake River Plain Aquifer. Sampling data from perched water zones 33 m below the release contain very high levels of (super 90) Sr as do soil samples obtained nearer the point of release. Use of traditional simulation approaches using laboratory-measured constant partitioning coefficients (K (sub d) ) cannot simultaneously explain perched water and soil concentrations. To address the discrepancy, a reactive transport approach was adopted to include competitive cation exchange, dissolution/precipitation of calcite, carbon dioxide gas production and transport, and gibbsite precipitation. Simulation results using this model suggest that some of the (super 90) Sr could have been transported very rapidly immediately after the release with the acceleration facilitated by competition for cation exchange sites with high sodium concentrations in the released liquid and calcium dissolved from calcite, and to a lesser extent by formation of aqueous complexes with nitrate. Once the leading edge of the liquid assemblage was flushed from the alluvium, the mobility of the remaining (super 90) Sr decreased significantly in the absence of the competing cations. Calculations indicate that there should be a net increase in calcite, suggesting that (super 90) Sr could be entrained in the mineral lattice, but insufficient field data exist for confirmation. Sensitivity studies show that the cation exchange selectivity coefficients were the most sensitive individual parameters determining the (super 90) Sr distribution. However, the most sensitive overall quantity was the total ion exchange capacity which is a function of the moles of exchange sites per volume of pore water, the cation exchange capacity, and the total volume wetted by the infiltrating solution. In contrast, the future mobility of (super 90) Sr was found to be relatively insensitive to the normal range in the composition of influxing precipitation and anthropogenic waters.

A simple graphite burn-off model was developed based on the similarities between a parallel electrical circuit and graphite oxidation. The developed model along with other comprehensive graphite oxidation models were integrated into the VHTR system analysis code, GAMMA. GT-MHR 600 MWt reactor was selected as a reference reactor. Based on the calculation, the main oxidation process was observed 5.5 days after the accident when followed by natural convection. The core maximum temperature reached 1430 degree C, but never exceeded the maximum temperature criteria, 1600 degree C. However, the oxidation process did significantly decrease the density of bottom reflector, making it vulnerable to mechanical stress. The stress on the bottom reflector is greatly increased because of the reduction of loaded surface area with graphite oxidation.

GEM, RGM, and particulate Hg (HgP) were also measured at a secondary site 90 km to the west in southwestern Idaho during the summer of 2006. The study was performed to characterize Hg air concentrations in the southern Idaho area for the first time, estimate Hg dry deposition rates, and investigate the source of observed elevated concentrations. High seasonal variability was observed with the highest GEM (1.91+ or -0.9 ngm (super -3) ) and RGM (8.1+ or -5.6 pg m (super -3) ) concentrations occurring in the summer and lower values in the winter (1.32+ or -0.3 ng m (super -3) , 3.2+ or -2.9 pg m (super -3) for GEM, RGM, respectively). The summer-average HgP concentrations were generally below detection limit (0.6+ or -1 pg m (super -3) ). Seasonally averaged deposition velocities calculated using a resistance model were 0.034+ or -0.032, 0.043+ or -0.040, 0.00084+ or -0.0017 and 0.00036+ or -0.0011 cm s (super -1) for GEM (spring, summer, fall and winter, respectively) and 0.50+ or -0.39, 0.40+ or -0.31, 0.51+ or -0.43 and 0.76+ or -0.57 cm s (super -1) for RGM. The total annual RGM+GEM dry deposition estimate was calculated to be 11.9+ or - 3.3 mu g m (super -2) , or about 2/3 of the total (wet+dry) deposition estimate for the area. Periodic elevated short-term GEM (2.2-12 ng m (super -3) ) and RGM (50-150 pg m (super -3) ) events were observed primarily during the warm seasons. Back-trajectory modeling and PSCF analysis indicate predominant source directions to the SE (western Utah, northeastern Nevada) and SW (north-central Nevada) with fewer inputs from the NW (southeastern Oregon and southwestern Idaho).

Input carbon losses occur in various locations within a pulp mill, including losses as volatile organics and wastewater. Opportunities exist to capture this carbon in the form of value-added products such as biodegradable polymers. Waste-activated sludge from a pulp mill wastewater facility was enriched for 80 days for a methanol-utilizing consortium with the goal of using this consortium to produce biopolymers from methanol-rich pulp mill waste streams. Five enrichment conditions were utilized: three high-methanol streams from the kraft mill foul condensate system, one methanol-amended stream from the mill wastewater plant, and one methanol-only enrichment. Enrichment reactors were operated aerobically in sequencing batch mode at neutral pH and 25°C with a hydraulic residence time and a solids retention time of 4 days. Non-enriched waste activated sludge did not consume methanol or reduce chemical oxygen demand. With enrichment, however, the chemical oxygen demand reduction over 24-h feed/decant cycles ranged from 79 to 89%, and methanol concentrations dropped below method detection limits. Neither the non-enriched waste-activated sludge nor any of the enrichment cultures accumulated polyhydroxyalkanoates (PHAs) under conditions of nitrogen sufficiency. Similarly, the non-enriched waste activated sludge did not accumulate PHAs under nitrogen-limited conditions. By contrast, enriched cultures accumulated PHAs to nearly 14% on a dry weight basis under nitrogen-limited conditions. This indicates that selectively enriched pulp mill waste activated sludge can serve as an inoculum for PHA production from methanol-rich pulp mill effluents.

Steady 2D RANS results are compared to unsteady 2D RANS results and experiment. The unsteady calculations account for the fact that nonturbulent fluctuations (due to vortex-shedding) are present in the flow. The unsteady computations are shown to predict the mean variables and the total shear stress quite well. Previous workers' results indicate that 3D simulations are needed to obtain reasonable agreement; present results indicate 2D is sufficient. Best practices are based on requirements for the ASME Journal of Fluids Engineering.

Flow systems composed of a heterogeneous porous media, as well as discrete fracture networks, have been cited as examples of systems that can exhibit episodic flow. Episodic outflow events are significant because relatively large volumes of water can move rapidly through an unsaturated system, carrying water and contaminants to depth greatly ahead of a wetting front predicted by a one-dimensional, gravity-driven diffusive infiltration model. In this study, we model the behavior of water flow through a sand column underlain by an impermeable-walled macropore. Relative permeability and capillary pressure relationships were developed that capture the complex interrelationships between the macropore and the overlying porous media that control flow out of the system. The potential for episodic flow is assessed and compared to results of conventional modeling approaches and experimental data from the literature. Model results using coupled matrix-macropore relative permeability and capillary pressure relationships capture the behavior observed in laboratory experiments remarkably well, while simulations using conventional relative permeability and capillary pressure functions fail to capture some of the observed flow dynamics. Capturing the rapid downward movement of water suggests that the matrix-macropore capillary pressure and relative permeability functions developed have the potential to improve descriptions of flow and transport processes in heterogeneous, variably saturated media.

The modified solution is applied incrementally through irradiation, which allows the material properties and irradiation temperature to change with time. It also removes the restriction in the original solution that Poisson's ratio in creep for the pyrocarbon layers be set to 0.5. It is presented in a manner that would enable its application to a system of any number of coating layers, not just the three layers of a TRISO-coated particle. The solution has been implemented in the PARFUME fuel performance code, where it has been demonstrated to perform efficiently in particle failure probability determinations.

We conducted column experiments to investigate the effect of mineralogy on the electrical signatures resulting from iron corrosion and mineral precipitation in Fe (super 0) columns using (a) Na (sub 2) SO (sub 4) , and (b) NaHCO (sub 3) plus CaCl (sub 2) mixture, solutions. At the influent interface where the reactions were most severe, a contrasting time-lapse electrical response was observed between the two columns. Solid phase analysis confirmed the formation of corrosion halos and increased mineralogical complexity in the corroded sections of the columns compared to the minimal/non-corroded sections. We attribute the contrasting time-lapse signatures to the differences in the electrical properties of the mineral phases formed within the two columns. While newly precipitated/transformed polarizable and semi-conductive iron oxides (mostly magnetite and green rust) increase the polarization and conductivity of the sulfate column, the decrease of both parameters in the bicarbonate column is attributed to the precipitation of non-polarizable and non-conductive calcite. Our results show that precipitate mineralogy is an important factor influencing the electrical properties of the corroded iron cores and must be considered if electrical geophysical methods are to be developed to monitor PRB barrier corrosion processes in situ.

Cosmogenic (super 10) Be surface-exposure ages from the terminal moraine in the North Fork Provo Valley and paired (super 26) Al and (super 10) Be ages from striated bedrock at Bald Mountain Pass set limits on the timing of the local LGM. Moraine boulder ages suggest that ice reached its maximum extent by 17.4+ or -0.5 ka (+ or -2sigma ). (super 10) Be and (super 26) Al measurements on striated bedrock from Bald Mountain Pass, situated near the former center of the ice field, yield a mean (super 26) Al/ (super 10) Be ratio of 5.7+ or -0.8 and a mean exposure age of 14.0+ or -0.5 ka, which places a minimum-limiting age on when the ice field melted completely. We also applied a mass/energy-balance and ice-flow model to investigate the LGM climate of the western Uinta Mountains. Results suggest that temperatures were likely 5 to 7 degrees C cooler than present and precipitation was 2 to 3.5 times greater than modern, and the western-most glaciers in the range generally received more precipitation when expanding to their maximum extent than glaciers farther east. This scenario is consistent with the hypothesis that precipitation in the western Uintas was enhanced by pluvial Lake Bonneville during the last glaciation.

Many sites require continued management efforts to: (1) protect the integrity of the engineered remedy/control, (2) limit the exposure of individuals to residual contamination by limiting reuse activities, (3) maintain ready access to accurate records/information, and (4) protect against vulnerabilities from intentional threats/actions. This article presents performance information from selected case studies to provide insight into various management approaches employed for addressing the risks associated with residual contaminants. The case studies involve sites remediated within the U.S. Comprehensive Environmental Response, Compensation, and Liability Act framework and illustrate two prevailing management approaches for addressing the risks. Sacrifice zones are sites that are purposefully isolated to prevent human access onto the property. Reuse sites provide limited access for specific use.

Accurate predictions of such heat transfer phenomena require high temperature thermal properties. However, a review of vessel and structural steel material properties in severe accident analysis codes reveals that the required high temperature material properties are extrapolated with little, if any, data above 700 DGC. To reduce uncertainties in predictions relying upon this extrapolated high temperature data, INL obtained data using laser-flash thermal diffusivity techniques for two metals used in LWR vessels: SA 533 Grade B, Class 1 (SA533B1) low alloy steel, which is used to fabricate most US LWR reactor vessels; and Type 304 Stainless Steel SS304, which is used in LWR vessel piping, penetration tubes, and internal structures. This paper summarizes the new data, compares it to existing data in the literature, and provides recommended correlations for thermal properties based on this data.

Ureolysis is an integral component of a novel remediation approach for divalent trace metal and radionuclide contaminants in groundwater and associated geomedia, where the contaminants are immobilized by coprecipitation in calcite. Generation of carbonate alkalinity from ureolysis promotes calcite precipitation. In calcite-saturated aquifers, this represents a potential long-term contaminant sequestration mechanism. In a single-well experiment, dilute molasses was injected three times over two weeks to promote overall microbial growth, followed by one urea injection. With molasses addition, total cell numbers in the groundwater increased 1-2 orders of magnitude. Estimated ureolysis rates in recovered groundwater samples increased from 25 nmol L super(-1) hr super(-1). A quantitative PCR assay for the bacterial ureC gene indicated that urease gene numbers increased up to 170 times above pre-injection levels. Following urea injection, calcite precipitates were recovered. Estimated values for an in situ first order ureolysis rate constant ranged from 0.016 to 0.057 d super(-1). Although collateral impacts such as reduced permeability were observed, overall results indicated the viability of manipulating biogeochemical processes to promote contaminant sequestration.

The benchmarks had no measurable displacement relative to one another at the resolution of the GPS during the 9-annum study, evidence that the province moves as a rigid, nonextending block. This scenario is supported by the aseismic nature of the province and the lack of measurable horizontal stress in boreholes. However, an additional small component of intraplain extension must also be invoked to account for the observed NW-trending volcanic rift zones that transect the eSRP. We suggest that intraplain extension is too slow (<1 mm/a) to measure using our campaign GPS methods, but may be sufficient over millennial timescales to accommodate rift zone formation. Slower velocities measured on three benchmarks within the neighboring Basin and Range "seismic parabola" are consistent with this region serving as a zone of detachment between the North American craton and the faster-moving eSRP.

For example, one must know if solvents are flowing in water-wetted or solvent-wetted environments, the pore-size distribution of the region containing DNAPLs, and the impact of contaminated plumes and their transport mechanisms in porous media. Our research investigates the capability and limitations of low-field proton nuclear magnetic resonance (NMR) relaxation decay-rate measurements for determining environmental properties affecting DNAPL solvent flow in the subsurface. The measurements that can be performed with the laboratory low-field system can also be performed in situ in the field with the current generation of commercial borehole logging tools. The oil and gas industry uses NMR measurements in deep subsurface, consolidated formations to determine porosity and hydrocarbon content and to estimate formation permeability. These determinations rely on the ability of NMR to distinguish between water and hydrocarbons in the pore space and to obtain the distribution of pore sizes from relaxation decay-rate distributions. In this paper, we will show how NMR measurement techniques can be used to characterize, monitor, and evaluate the dynamics of mixed fluids (water-DNAPL) in unconsolidated near- surface porous environments, and describe the use of proton NMR T sub(2) (spin-spin relaxation time) measurements in unconsolidated sandy-soil samples to identify and characterize the presence of DNAPLs in these environments. The potential of NMR decay-rate distributions for characterizing DNAPL fluids in the subsurface and understanding their flow mechanisms has not previously been exploited; however, near-surface unsaturated vadose zone environments do provide unique challenges for using NMR measurements. These challenges are addressed through systematic laboratory experiments and a program of research to extend and adapt current field NMR measurements to near-surface environmental problems.

The production-scale availability of recombinant mussel adhesive proteins will enable researchers to formulate adhesives that are water-impervious and ecologically safe and can bind materials ranging from glass, plastics, metals, and wood to materials, such as bone or teeth, biological organisms, and other chemicals or molecules. Unfortunately, as of yet scientists have been unable to duplicate the processes that marine mussels use to create adhesive structures. This study provides a background on adhesive proteins identified in the blue mussel, Mytilus edulis, and introduces our research interests and discusses the future for continued research related to mussel adhesion.

Two tracer tests were performed using the Vadose Zone Research Park (VZRP) at the Idaho National Laboratory (INL). The first test occurred under quasi-steady-state conditions and the second was initiated in a much drier system and thus provided information regarding flow and transport under transient conditions. A one-dimensional analytical model was used to fit breakthrough curves resulting from the two tracer tests. The results of this modeling provide insight into the nature of flow in the fractured basalt, surficial alluvium, and sedimentary interbeds that comprise the vadose zone of the eastern Snake River Plain. Flow through the fractured basalt is focused and preferential in nature, and multiple flow paths arise due to numerous fractures functioning as transmissive pathways in addition to flow splitting along geologic contacts. Flow velocities were significantly higher during the test with the wetter flow domain, presumably due to increases in hydraulic conductivity associated with higher water contents of the geologic materials. Perching was observed above the alluvium-basalt contact and above the lower boundary of a locally continuous sedimentary interbed. The perching behavior between the two contacts was fundamentally different; the perched layer above the alluvium-basalt contact was neither laterally extensive nor temporally persistent in the absence of infiltration from the surface. In contrast, the perched layer along the interbed was significantly thicker and gave rise to lateral flow over distances on the order of hundreds of meters. Vertical transport is shown to occur predominantly through the main bulk of the sedimentary material of the interbed; lateral flow appears to occur primarily in the fractured basalt directly above the interbed.

Consequently, as the deployment of cellulosic ethanol biorefineries approaches, feedstock cost and availability are the driving factors that influence pioneer biorefinery locations and will largely control the rate at which this industry grows. Initial scenarios were postulated to develop a pioneer dry feedstock supply system design case as a demonstration of the current state of technology. Based on this pioneer design, advanced scenarios were developed to determine key cost barriers, needed supply system improvements, and technology advancements to achieve government and private sector cost targets. Analysis of the pioneer supply system resulted in a delivered feedstock cost to the throat of the pretreatment reactor of $37.00 per dry tonne (2002 $). Pioneer supply systems will start by using current infrastructure and technologies and be individually designed for biorefineries using specific feedstock types and varieties based on local geographic conditions. As the industry develops and cost barriers are addressed, the supply systems will incorporate advanced technologies that will eliminate downstream diversity and provide a uniform, tailored feedstock for multiple biorefineries located in different regions.

AN - 68232885; 17659876 AB - Independent numerical simulations have been performed using the MCNP5 and SCALE5 radiation transport codes to evaluate the effectiveness of a concrete facility designed to shield personnel from neutron radiation emitted from DT neutron generators. The analysis considered radiation source terms of 14.1 MeV monoenergetic neutrons located at three discrete locations within the two test vaults in the facility, calculating neutron and photon dose rates at 44 locations around the facility using both codes. In addition, dose rate contours were established throughout the facility using the MCNP5 mesh tally feature. Neutron dose rates calculated outside of the facility are predicted to be below 0.01 mrem/h at all locations when all neutron generator source terms are operating within the facility. Similarly, the neutron dose rate in one empty test vault when the adjacent test vault is being utilized is also less then 0.01 mrem/h. For most calculation locations outside the facility the photon dose rates were less then the neutron dose rates by a factor of 10 or more.

That is, we describe a method of sampling the space of inverse solutions that honor a specified semivariogram or set of semivariograms and also explain a set of state data. The approach can be considered a method of conditional simulation where model conditioning is based upon state data (as opposed to parameter data). The difference between this approach and other simulation approaches is that the simulation is posed as an optimization problem with the joint objective of matching the semivariograms and honoring the state data. This approach requires computing the sensitivities of the semivariograms with respect to the distributed parameter. We derive these sensitivities and find that they are efficient to compute and store, making the method tenable for large models. We demonstrate the method with one synthetic and one field example using radar velocity tomography, where radar velocity is related through a petrophysical transform to saturated porosity. We address biasing issues and demonstrate ensemble generation and the resulting resolution and uncertainty analysis using ensemble statistics. We also demonstrate how the method can be applied to existing deterministic inversion codes with the field example. Copyright 2007 by the American Geophysical Union.

Some of these systems have been in continuous operation for over 12 years. It is important that the systems be physically robust, simple, yet versatile enough that it can operate for extended time periods with little or no maintenance. Monitoring instruments are frequently installed and run to characterize the site, collect data during site operation, and continue to run for long-term stewardship, necessitating sensors that can be maintained or serviced. Sensors are carefully chosen based on the perceived data requirements over the life of the site. An emphasis is given on direct measurements such as tensiometers (portable and advanced), neutron probe, drain gauge, temperature, wells or sampling for fluids and gases. Other complementary data can include using TDR/capacitance, radiation detectors, and larger scale geophysical techniques (3-d resistivity and EM) for volumetric measurements. Commercially available instruments may have to be modified for their use at greater depths, to allow multiple instruments in a single borehole or to perform the intended monitoring function. Access tubes (some open at the bottom) can be placed to allow insertion of multiple sensors (radiation, neutron and portable sensors/samplers), future drilling/sampling and to install new instruments at a later time. The installation techniques and backfill materials must be chosen and the measurement technique tested to ensure representative data collection for the parameters of interest. The data collection system can be linked to climatic data (precipitation, barometric pressure, snow depth, runoff, surface water sources) that may influence the site's subsurface hydrology. The instruments are then connected to a real-time automated data collection system that collect, stores, and provides access to the data. These systems have been developed that allow easy access, automatic data quality checks with notification, processing, and presentation of the data in real time through the web. The systems can be designed to manipulate/test the system remotely. Data from several sites will be presented showing that continuous monitoring is necessary to detect rapid changes in the deep vadose zone and ground water at fractured rock sites.

In this research, we explore the feasibility of applying complex resistivity to the detection and monitoring of microbially-induced reduction of hexavalent chromium (Cr(VI)) to a less toxic form (Cr(III)). We hope to measure the change in ionic concentration that occurs during this reduction reaction. This form of reduction promises to be an attractive alternative to more expensive remedial treatment methods. The specific goal of this research is to define the minimum and maximum concentration of the chemical and biological compounds in contaminated samples for which the Cr(VI) - Cr(III) reduction processes could be detected via complex resistivity. There are three sets of experiments, each comprised of three sample columns. The first experiment compares three concentrations of Cr(VI) at the same bacterial cell concentration. The second experiment establishes background samples with, and without, Cr(VI) and bacterial cells. The third experiment examines the influence of three different bacterial cell counts on the same concentration of Cr(VI). A polarization relaxation mechanism was observed between 10 and 50 Hz. The polarization mechanism, unfortunately, was not unique to bio-chemically active samples. Spectral analysis of complex resistivity data, however, showed that the frequency where the phase minimum occurred was not constant for bio-chemically active samples throughout the experiment. Significant shift in phase minima occurred between 10 to 20 Hz from the initiation to completion of Cr(VI) reduction. This phenomenon was quantified using the Cole-Cole model and the Marquardt-Levenberg nonlinear least square minimization method. The data suggest that the relaxation time and the time constant of this relaxation are the Cole-Cole parameters most sensitive to changes in biologically-induced reduction of Cr(VI).

All major fuel-related design parameters (burnup, temperature, fast neutron fluence, power density, particle packing fraction) exceed the values that were qualified in the successful German UO2 coated particle fuel development program in the 1980s. Of particular concern are the high burnup and high temperatures expected in the very high temperature reactor. In this paper, the challenges associated with high burnup and high temperature are evaluated quantitatively by examining the performance of the fuel in terms of different known failure mechanisms. Potential design solutions to ameliorate the negative effects of high burnup and high temperature are discussed. Also of concern are the effects of accelerated irradiation on coated fuel that often occur during irradiation testing. These effects are evaluated in this paper and recommendations concerning allowable levels of accelerations are presented.

But the emergence of new R&D programs points to a need to understand how best to plan for a long-term fuel development program. The rationale for such a program is not easily found in the literature, so the authors have suggested a structure and rationale. The approach is described as four phases, with emphasis on selecting a reference fuel concept, evaluating and improving the fuel to develop a fuel specification for a reference design, obtaining data to support a licensing safety case for the fuel, and final qualification of the fuel for a specific application. Because a fuel program requires long-lead-time irradiation testing, bringing a fuel design from the initial concept through licensing might take over 20 years.

All three types have been demonstrated capable of fuel utilization at or above 200 GWd/MTHM. To varying degrees, life-limiting phenomena for each type have been identified and investigated, and there are no disqualifying safety-related fuel behaviors. All three fuel types appear capable of meeting requirements of sodium-cooled fast reactor fuels, with reliability of mixed oxide and metal fuel well established. Improvements in irradiation performance of cladding and duct alloys have been a key development in moving these fuel designs toward higher-burnup potential. Selection of one fuel system over another will depend on circumstances particular to the application and on issues other than fuel performance, such as fabrication cost or overall system safety performance.

results of a large-scale experiment AN - 51100556; 2007-107326 AB - A meter-scale experimental system (2-m high by 2-m deep by 3-m wide) was used to investigate the behavior of water in a model system consisting of two unconsolidated sediment layers separated by a layer containing discrete flow channels. Stainless steel tubes were inserted vertically through a clayey matrix to represent the discrete flow-channel layer. The experimental system was well characterized, and results from water infiltration experiments were analyzed. A time series of water arrival at a network of 86 probes located in the unconsolidated sediment layers is presented, as well as water pressure histories at specific locations. Some probes were located at opposite ends of the flow channels to assess water migration through the discrete flow-channel layer. Analyses of the experimental results focused on capillary break phenomenon at the interface between the overlying unconsolidated layer and the underlying discrete flow channels. Dissimilar water pressure histories were measured at probes near the upper boundary of the discrete flow-channel layer, suggesting varied and complex water flow behavior. At some locations, a steady or periodic "leaking" of water through the discrete flow channels appeared to occur, contrary to capillary break theory. The authors advocate larger-scale experiments to advance our understanding and ability to model fluid flow across a wide range of spatial and temporal scales.

The practice of precursor analysis has been a part of nuclear power plant regulation in the United States for over 25 years. During this time, the models used in the analysis have evolved from simple risk equations to quite complex probabilistic risk assessments. But, one item that has remained constant over this time is that the focus of the analysis has been on modeling the scenario using the risk model (regardless of the model sophistication) and then using the results of the model to determine the severity of the precursor incident. We believe that evaluating precursors in this fashion could be a shortcoming since decision making during the incident is not formally investigated. Consequently, we present the idea for an evaluation procedure that enables one to integrate current practice with the evaluation of decisions made during the precursor event. The methodology borrows from technologies both in the risk analysis and the decision analysis realms. We demonstrate this new methodology via an evaluation of a U.S. precursor incident. Specifically, the course of the incident is represented by the integration of a probabilistic risk assessment model (i.e., the risk analysis tool) with an influence diagram and the corresponding decision tree (i.e., the decision analysis tools). The results and insights from the application of this new methodology are discussed.

Franklinite (ZnFe2O4) was observed in both samples. Hematite ( alpha -Fe2O3), crystalline silica (SiO2), a fine-grained mixture of iron oxides probably including magnetite (Fe3O4), hematite ( alpha -Fe2O3), and goethite ( alpha -FeOOH), and an unidentified high-Ba, high-S phase were observed in one of the samples. Willemite (Zn2SiO4), amorphous silica, and an unidentified iron-chromium phase were observed in the other. Chloride-bearing phases were found in both samples, and are assumed to represent sample contaminants. Because of the small sample volumes and numbers of particles studied and the possibility of contamination, it is not clear whether the differences between the phases observed in the two crud samples represent actual differences in the assemblages formed in the reactors.

In support of the growing interest in agricultural crop residues as a bioenergy feedstock, we have extended the capability of the DSS4Ag to develop a variable-rate fertilizer recipe for the simultaneous economically optimum production of both grain and straw. In this paper we report the results of 2 yr of field research testing and enhancing the DSS4Ag's ability to economically optimize the fertilization for the simultaneous production of both grain and its straw, where the straw is an agricultural crop residue that can be used as a biofeedstock. For both years, the DSS4Ag reduced the cost and amount of fertilizers used and increased grower profit, while reducing the biomass produced. The DSS4Ag results show that when a biorefinery infrastructure is in place and growers have a strong market for their straw it is not economically advantageous to increase fertilization in order to try to produce more straw. This suggests that other solutions, such as single-pass selective harvest, must be implemented to meet national goals for the amount of biomass that will be available for collection and use for bioenergy.

In this paper, the application of dissipative particle dynamics (DPD), a relatively new mesoscale method, to the simulation of pore-scale multiphase fluid flows under a variety of flow conditions is described. We demonstrate that the conventional DPD method using purely repulsive conservative (nondissipative) particle-particle interactions is capable of modeling single-phase flow fields in saturated porous media. In order to simulate unsaturated multiphase flow through porous media, we applied a modified model for the conservative particle-particle interactions that combines short-range repulsive and long-range attractive interactions. This form for the conservative particle-particle interactions allows the behavior of multiphase systems consisting of gases, liquids, and solids to be simulated. We also demonstrated that the flow of both wetting and nonwetting fluids through porous media can be simulated by controlling the ratios between the fluid-fluid and fluid-solid (fluid-wall) interparticle interaction strengths.

Nine PAH compounds representing four chemical classes of PAH (unsubstituted, acetyl-, amino-, and nitro-substituted) were applied onto the surface of quartz, plagioclase, olivine, and ilmenite mineral standards and analyzed using laser desorption/ionization Fourier transform mass spectrometry (LD- FTMS). Mass-to-charge peaks derived from PAH compounds were detected from the surfaces of all minerals evaluated. All PAH compounds were detected in the positive ion mode, whereas only nitro-substituted PAH compounds were detected in negative ion mode. In this and earlier studies, the ability to directly detect mineral-associated AAs by LD-FTMS was dependent on the mineral geomatrix. On iron-bearing minerals AAs appeared as highly fragmented ions in the spectra or were not detectable; however, the addition of the PAH chrysene enabled the ionization and detection of AAs threonine and histidine by LD- FTMS. Thus, for mineral systems such as meteorites, interstellar dust particles, soils, and sediments, the co-detection of AAs associated with PAHs by LD-FTMS is feasible.

8054062 AB - The international reactor innovative and secure (IRIS) is a modular pressurized water reactor with an integral configuration (all primary system components - reactor core, internals, pumps, steam generators, pressurizer, and control rod drive mechanisms - are inside the reactor vessel). The IRIS plant conceptual design was completed in 2001 and the preliminary design is currently underway. The pre-application licensing process with the United States Nuclear Regulatory Commission (USNRC) started in October 2002. The first line of defense in IRIS is to eliminate event initiators that could potentially lead to core damage. If it is not possible to eliminate certain accidents altogether, then the design inherently reduces their consequences and/or decreases their probability of occurring. One of the most obvious advantages of the IRIS Safety-by-Design approach is the elimination of large break loss-of-coolant accidents (LBLOCAs), since no large primary penetrations of the reactor vessel or large loop piping exist. While the IRIS Safety-by-Design approach is a logical step in the effort to produce advanced reactors, the desired advances in safety must still be demonstrated in the licensing arena. With the elimination of LBLOCA, an important next consideration is to show the IRIS design fulfills the promise of increased safety also for small break LOCAs (SBLOCAs). Accordingly, the SBLOCA phenomena identification and ranking table (PIRT) project was established. The primary objective of the IRIS SBLOCA PIRT project was to identify the relative importance of phenomena in the IRIS response to SBLOCAs. This relative importance, coupled with the current relative state of knowledge for the phenomena, provides a framework for the planning of the continued experimental and analytical efforts. To satisfy the SBLOCA PIRT project objectives, Westinghouse organized an expert panel whose members were carefully selected to insure that the PIRT results reflect internationally recognized experience in reactor safety analysis, and were not biased by program preconceptions internal to the IRIS program. The SBLOCA PIRT Panel concluded that continued experimental data and analytical tool development in the following areas, in decreasing level of significance, are perceived as important with respect to satisfying the safety analysis and licensing objectives of the IRIS program: (1) steam generator; (2) pressure suppression system, containment dry well and their interactions; (3) emergency heat removal system; (4) core, long-term gravity makeup system, automatic depressurization system, and pressurizer; (5) direct vessel injection system and reactor vessel cavity.

7415959 AB - Multiphase fluid motion in unsaturated fractures and fracture networks involves complicated fluid dynamics, which is difficult to model using grid- based continuum methods. In this paper, the application of dissipative particle dynamics (DPD), a relatively new mesoscale method to simulate fluid motion in unsaturated fractures is described. Unlike the conventional DPD method that employs a purely repulsive conservative (non-dissipative) particle-particle interaction to simulate the behavior of gases, we used conservative particle- particle interactions that combine short-range repulsive and long-range attractive interactions. This new conservative particle-particle interaction allows the behavior of multiphase systems consisting of gases, liquids and solids to be simulated. Our simulation results demonstrate that, for a fracture with flat parallel walls, the DPD method with the new interaction potential function is able to reproduce the hydrodynamic behavior of fully saturated flow, and various unsaturated flow modes including thin film flow, wetting and non- wetting flow. During simulations of flow through a fracture junction, the fracture junction can be fully or partially saturated depending on the wetting property of the fluid, the injection rate and the geometry of the fracture junction. Flow mode switching from a fully saturated flow to a thin film flow can also be observed in the fracture junction.

AN - 68959260; 17265940 AB - The potential for biological reduction of Cr(VI) under acidic conditions was evaluated with the acidophilic, facultatively metal-reducing bacterium Acidiphilium cryptum strain JF-5 to explore the role of acidophilic microorganisms in the Cr cycle in low-pH environments. An anaerobic suspension of washed A. cryptum cells rapidly reduced 50 microM Cr(VI) at pH 3.2; biological reduction was detected from pH 1.7-4.7. The reduction product, confirmed by XANES analysis, was entirely Cr(III) that was associated predominantly with the cell biomass (70-80%) with the residual residing in the aqueous phase. Reduction of Cr(VI) showed a pH optimum similar to that for growth and was inhibited by 5 mM HgCl2, suggesting that the reaction was enzyme-mediated. Introduction of O2 into the reaction medium slowed the reduction rate only slightly, whereas soluble Fe(III) (as ferric sulfate) increased the rate dramatically, presumably by the shuttling of electrons from bioreduced Fe(II) to Cr(VI) in a coupled biotic-abiotic cycle. Starved cells could not reduce Cr(VI) when provided as sole electron acceptor, indicating that Cr(VI) reduction is not an energy-conserving process in A. cryptum. We speculate, rather, that Cr(VI) reduction is used here as a detoxification mechanism.

The Idaho National Laboratory, in collaboration with the US Geological Survey, virtually assessed the gross power potential of all natural streams in the USA, identified feasible potential project sites and estimated their power potential which could be developed. The results of this virtual prospecting have been incorporated into a GIS application called the Virtual Hydropower Prospector, which is available for public use on the Internet.

Rate Constants and Degradation Mechanisms of Trichloronitromethane (Chloropicrin) AN - 20619842; 7984704 AB - Absolute rate constants for the free-radical-induced degradation of trichloronitromethane (TCNM, chloropicrin) were determined using electron pulse radiolysis and transient absorption spectroscopy. Rate constants for hydroxyl radical, super(bull)OH, and hydrated electron, e sub(aq) super(-), reactions were (4.97 plus or minus 0.28) x 10 super(7) M super(-) super(1) s super(-) super(1) and (2.13 plus or minus 0.03) x 10 super(10) M super(-) super(1) s super(-) super(1), respectively. It appears that the super(bull)OH adds to the nitro-group, while the e sub(aq) super(-) reacts via dissociative electron attachment to give two carbon centered radicals. The mechanisms of these free radical reactions with TCNM were investigated, using super(60)Co gamma irradiation at various absorbed doses, measuring the disappearance of TCNM and the appearance of the product nitrate and chloride ions. The rate constants and mechanistic data were combined in a kinetic computer model that was used to describe the major free radical pathways for the destruction of TCNM in solution. These data are applicable to other advanced oxidation/reduction processes.

Synechococcus sp. strain PCC 8806 and Synechococcus sp. strain PCC 8807 were tested in microcosm experiments for their ability to calcify when exposed to a fixed calcium concentration of 3.4 mM and dissolved inorganic carbon concentrations of 0.5, 1.25 and 2.5 mM. Synechococcus sp. strain PCC 8806 removed calcium continuously over the duration of the experiment producing approximately 18.6 mg of solid phase calcium. Calcium removal occurred over a two-day time period when Synechococcus sp. strain PCC 8807 was tested and only 8.9 mg of solid phase calcium was produced. Creation of an alkaline growth environment catalyzed by the physiology of the cyanobacteria appeared to be the primary factor responsible for CaCO sub(3) precipitation in these experiments.

thermodynamic calculations using variable space group designations to determine the symmetry relation to stability from ab initio quantum mechanical density functional theory techniques AN - 807614073; 2010-095825 AB - The jarosite mineral group has come to the forefront of planetary geology since it was discovered on the surface of Mars by the Mars Exploration Rover-Opportunity in 2004. Analytical techniques have reported considerable variations in the space group designations of this mineral group. These variations are likely due to entropy differences in the formation environment that result in alternative crystal symmetries. A fundamental investigation of this phenomenon has yet to be undertaken. This study is a preliminary determination of the ability of density functional theory generalized gradient approximations (DFT-GGA) to accurately determine general thermodynamic parameters of the jarosite mineral group. Calculations using variations in space group designation were performed to better understand the effect that space group and symmetry have on density functional theory approximations of thermodynamic variables in the complex crystal structure of jarosite. Theoretical values were compared to experimental values to determine the validity of the DFT-GGA technique and to determine the role that symmetry has on the stability of the mineral group. In order to accomplish calculations of this magnitude, we have employed the Columbia supercomputer at NASA Ames Advanced Computing Center which has allowed us to complete calculations using all the current variations of DFT-GGA. These results are a gateway to determining the validity of using theoretical methods for large complex mineralogical systems. Application of theoretical techniques based on first principles approximations will allow mineralogists to accurately predict the properties of minerals from theoretical thermodynamic calculations and apply them to extraterrestrial environments.

Quantitative models of biogeochemical reaction systems are based on constituent concentration as the primary dependent variable, which requires assumptions involving scales of averaging and mixing. At laboratory scales, complete mixing and homogeneity conditions can be (and usually are) enforced and resulting theories are conditioned on those assumptions. However, at field scales physical, chemical and biological heterogeneity and incomplete mixing are the rule rather than the exception. Several examples from recent research, including experiments and simulations ranging from pore to field scales, will be presented to illustrate these issues and identify possible solutions. These examples include a combined field- and laboratory-scale study of bacterial transport, a field study of metals bioremediation in a highly heterogeneous aquifer, and pore- to continuum-scale simulations of coupled flow and mineral precipitation reactions.

The challenge at hand is how to perform performance monitoring in a cost effective, timely, rigorous and scientifically defensible manner while meeting multiple stakeholder needs. Such stakeholders will typically include regulators, owners, scientists and the general public, each of which have different information objectives (which could. be regulatory, performance related, process related or impact related). The commonality for all these objectives in that the information generation process should be transparent, reproducible and auditable. Historically the problem with performance monitoring related information generation process is that--due to the decoupled nature between the components of performance monitoring (data acquisition. data management, data processing, data interpretation/result generation and result delivery)--these objectives are not met. Over the last several years we have developed and implemented a web accessible scientific workflow system which allows for a systematic way in which to meet these objectives. By providing a web frontend to a central backend (which can tap into several auditable data and model sources) data becomes easily auditable, tools become available to end users, and stakeholder specific site information can be efficiently generated and delivered. We will present and discuss both the general philosophy behind this system as provide several examples of system implementations.

At the influent sand/iron interface channels where iron corrosion and mineral precipitation were initiated and most severe, an increase in interfacial polarization ( approximately 250% for sulfate, approximately 100% for nitrate column) and decrease in resistivity ( approximately 30% for sulfate, approximately 12% for nitrate) were observed in sulfate and nitrate columns. In contrast, the bicarbonate column shows a decrease in interfacial polarization ( approximately 30%) and an increase in resistivity ( approximately 7%). Scanning electron microscopy (SEM) and X-ray diffractometry (XRD) analysis revealed the formation of corrosion rinds and the increasing mineralogical complexity in corroded sections of the core compared to minimal/non corroded sections. We attribute the different electrical behavior of the bicarbonate relative to the sulfate/nitrate columns to mineralogical differences resulting from iron corrosion and mineral precipitation within the columns: While newly precipitated/transformed polarizable and conductive/semi-conductive iron (oxyhydr)oxides (mostly magnetite) causes the increase in interfacial polarization and decrease in resistivity in sulfate and nitrate columns due to increased polarizable surface area and mineralogical alteration, the decreased interfacial polarization and increased resistivity in the bicarbonate column are attributed to non-polarizable and non-conductive carbonate mineral precipitation coating the zero-valent iron surface and decreasing interfacial and electronic conduction. Our result shows that mineralogy is a critical factor that influences electrical properties, and this should be taken into account when considering the use of electrical methods to monitor PRB barrier corrosion processes in situ.

Time-lapse geophysical approaches, such as electrical-resistivity tomography, can provide site operation managers with near real-time information about the spatial distribution of injected fluids, remedial amendments, and water quality. We provide an overview of two field experiments involving application of time-lapse geophysical methods to monitor (1) aquifer storage and recovery (ASR); and (2) biostimulation with emulsified vegetable oil. Case studies from an ASR pilot-scale experiment in Charleston, South Carolina, and a biostimulation experiment in Fridley, Minnesota demonstrate that geophysical methods provide valuable insight into mass transport at the site-scale; however, our experience also indicates that site managers and decision makers prefer summary performance indicators to more complex geophysical results, the interpretation of which commonly requires an understanding of image resolution and measurement sensitivity. Translating geophysical results into relevant performance indicators remains an important challenge for realizing the full potential of near-surface geophysics for performance monitoring. Toward this end, we investigate alternative approaches to conventional inversion of geophysical data: (1) moment-based inversion (MBI); and (2) object-based inversion (OBI). For time-lapse imaging of transport processes, MBI yields estimates of plume moments (e.g., total mass, center of mass, spread, etc.), providing direct insight into advection, dispersion, and mass transfer. OBI parameterization is guided by geologic and hydrologic insight into the target, e.g., a layered block model describing the shape of an amendment plume injected into stratified media. The MBI and OBI inversion methods reduce inversion artifacts, simplify interpretive complexity, and translate geophysical data into actionable information by estimating parameters of direct interest to engineers and hydrologists.

Flow systems characterized by a porous media underlain by a macropore and discrete fracture networks have been cited in recent literature as examples of systems that can exhibit episodic outflow behavior. These outflow events are significant because relatively large volumes of water can move rapidly through an unsaturated system, carrying water and possibly contaminants to depth greatly ahead of a diffusive wetting front. In this study, we examine the modeled behavior of water flow through a sand column underlain by a vertical capillary tube, focusing our evaluation on the potential for episodic flow between the two domains and the effect of potential diffusive losses through the wall of the simulated macropore once an episodic event is initiated. The modeling results are compared with experimental data from the literature. Particular attention is given to capillary pressure relationships between the porous media and the macropore, as the complex interrelationships between these domains generate the initiation or cessation of flow.

Similar polymers have been successfully used in the petroleum industry for analogous applications, but this technology has not been applied to environmental remediation activities. Polymers are capable of swelling thousands of times their original size when triggered by changes in pH and ionic strength while exhibiting a very low permeability. Therefore, polymers have the potential to significantly reduce permeability of geologic media, redirecting water infiltration away from contaminated regions of the subsurface. These polymers are polyacrylic acids that when mixed with water, exhibit initial fluid properties similar to water at pH between 2.0 ï¿1/2 4.0. The solutions are introduced into geologic materials where the acidic solution reacts with the minerals and in situ pore water, altering the pH and the ionic strength of the solution. These changes trigger an increase in solution viscosity as the polymers swell, plugging pores and reducing permeability. The polymer kinetics of these reactions are controlled by the geologic mineralogy, solution flux rate, polymer concentrations, and solvent chemistry. Researchers at the Idaho National Laboratory Research Center evaluated field emplacement methods that impact polymer rheology kinetics by conducting soil batch experiments and column studies with two commercially available polymers. The researchers were able to identify appropriate polymer and solvent concentrations, solution flux rates, and reaction times required to significantly reduce soil permeability. This poster presentation will present the laboratory methods developed to evaluate the use of polymers for environmental remediation activities and results of these tests.

Source contamination typically was a localized leak in surface or near-surface process equipment. Immobilizing or sequestering such contaminants in situ is a preferred remediation technique for economic and technical reasons. In situ contaminate stabilization can be challenging when the subsurface geology is complex and highly heterogeneous. The contaminate stabilization is accomplished by introducing an amendment, water- soluble polymer, into contact with the contaminated porous medium. This paper will present results from a series of laboratory experiments preformed in layered heterogeneous tanks that were monitored using 4 D electrical resistivity, temperature, conductivity of incoming and outgoing tank fluids. The experiments were designed to show that monitoring as well as sequestering radionuclides (Sr90) in perched groundwater within fractured media was possible.

Silver ions were implanted in beta -SiC using the ATLAS accelerator facility at the Argonne National Laboratory. Ion beams with energies of 93 and 161 MeV were used to achieve deposition with peak concentrations of approximately 26 wt% at depths of approximately 9 and 13 is a subset of m, respectively. As-implanted samples were then annealed at 1500 °C for 210 or 480 h. XPS, SEM, TEM, STEM, and optical methods were used to analyze the material before and after annealing. Silver concentration profiles were determined using XPS before and after annealing. STEM and SEM equipped with quantitative chemical analysis capability were used to more fully characterize the location and morphology of the silver before and after annealing. The results show that, within the uncertainty of measurement techniques, there is no silver migration, via either inter- or intra-granular paths, for the times and temperature studied. Additionally, the silver was observed to phase separate within the SiC after annealing. The results of this work do not support the long held assumption that silver release from CVD SiC, used for gas-reactor coated particle fuel, is dominated by grain boundary diffusion.

An improved understanding of the INL vadose zone will support ground water monitoring, Wastewater Land Application Permits (WLAP), remediation of contamination sites, and constructing new facilities. The Vadose Zone Research Park (VZRP) is located at the new Idaho Nuclear Technology and Engineering Center percolation pond and includes a stretch of the Big Lost River. Data collected as part of an ongoing LDRD project being conducted at the VZRP captured water infiltration and redistribution from two flow events a 10-day flow event in June 2005 and two month event in summer of 2006. The data supports preferential- type flow behavior similar to percolation pond infiltration observations, rapid formation of perched water at various depths, non-sequential vertical and lateral water arrival, and a high degree of spatial variability in geohydrologic properties. Continued monitoring of hydraulic response to changes in the Big Lost River (BLR) flux, will aid INL and the Idaho Cleanup Project (ICP) operations in design and development of future waste disposal sites.

Models for heterogeneous porous media were generated by using randomly located non-intersecting circular grains of different sizes, and pore scale anisotropy was introduced by randomly inserting non-overlapping particles on either side of the gap between two self-affine fractal curves to create a microfracture. Different fluid wetting behaviors and surface tensions were modeled using pair-wise particle-particle interactions. In simulations of miscible fluid flow, particles with variable, composition dependent, masses and viscosities were used. Artificial surface tension effects were avoided by basing the SPH equations on the particle number density. Abstract Copyright (2006) Elsevier, B.V.

8549920 AB - The fundamental design for a gas-cooled reactor relies on the behavior of the coated particle fuel. The coating layers surrounding the fuel kernels in these spherical particles, consisting of pyrolytic carbon and silicon carbide layers, act as a pressure vessel that retains fission products. Many more fuel particles have failed in US irradiations than would be expected when only one-dimensional pressure vessel failures are considered. Several multi-dimensional failure mechanisms that may have contributed to these failures have been previously studied, such as (1) irradiation-induced shrinkage cracks in the inner pyrocarbon (IPyC) layer, (2) partial debonding between the IPyC and SiC layers, and (3) deviations from a perfectly spherical shape. A further phenomenon that could lead to particle failures is thinning of the SiC layer caused by either thermal decomposition or interaction with fission products. Results of a study of the effects of SiC thinning and criteria for evaluating this behavior in a fuel performance code are presented.

Specimen blanks were exposed to reference transients with 810 and 840 DGC maximum temperatures using a thermal cycle simulator, and the subsequent microstructure, hardness, and creep-rupture strength were evaluated. Exposure to five consecutive cycles at either temperature resulted in no significant changes - only very slight indications of overtempering. Subsequent study of a wider variety of transient conditions showed that significant ferrite-to-austenite transformation occurred during thermal transients whose maximum temperature exceeded 860 DGC, or during transients with holds exceeding 10 s at 840 DGC maximum temperature. The subsequent presence of untempered martensite in the microstructure, coupled with severe overtempering, resulted in an order of magnitude decrease in creep-rupture strength at 600 DGC.

To produce pollucite and other mineral analogs of the alkaline metals, the feeds must be mixed with aluminosilicate compounds and thermally sintered or calcined to activate solid-state crystal formation. Scoping tests completed indicated that the cesium/strontium in these organic and acid solutions can be converted into aluminosilicate materials using steam reforming.

Fed-batch studies with nitrate as the primary electron acceptor showed that accumulation of nitrite led to a decrease in the extent of selenite reduction. Also, when nitrite was added as the primary electron acceptor, rapid selenite reduction was observed only after nitrite was significantly depleted from the medium. These results indicate that selenite reduction was inhibited at high nitrite concentrations. In addition to batch experiments, continuous-flow selenite reduction experiments were performed in packed-bed columns using immobilized enrichment cultures. These experiments were carried out in three phases: in phase I, a continuous nitrate feed with different inlet selenite concentration was applied; in phase II, nitrate was fed in a pulsed fashion; and in phase III, nitrate was fed in a continuous mode but at much lower concentrations than the other two phases. During the phase I experiments, little selenite was removed from the influent. However, when the column was operated in the pulse feed strategy (phase II) or in the continuous mode with low nitrate levels (phase III), significant quantities of selenium were removed from solution and retained in the immobilization matrix in the column. Thus, immobilized denitrifying cultures can be effective in removing selenium from waste streams, but nitrate-limited operating conditions might be required.

The motivation of this work is to develop an IMF with a thermal conductivity superior to that of the fuels based on yttria stabilized zirconia. The concept uses the MgO phase as an efficient heat conductor to increase thermal conductivity of the composite. In this paper ceramic fabrication and characterization by scanning electron microscopy, energy and wavelength dispersive X-ray spectroscopy is discussed. Characterization shows that the ceramics consist of the two-phase matrix and PuO2-rich inclusions. The matrix is comprised of pure MgO phase and MgO-ZrO2-PuO2 solid solution. The PuO2-rich inclusion contained dissolved MgO and ZrO2. JF - Journal of Nuclear Materials AU - Medvedev, P G AU - Jue, J F AU - Frank, S M AU - Meyer, M K AD - Idaho National Laboratory, P.O.

It is one of the high temperature candidate alloys being considered for Generation IV nuclear reactor systems. The radiation resistance of 800H has not been previously studied. This work provides information on the microstructural changes in 800H after irradiation using 5.0 MeV Ni ions at 500 DGC to 5 and 50 dpa. Following irradiation, changes in microstructure and phase stability were studied using transmission electron microscopy (TEM). At a dose of 50 dpa, no voids were found and the density and size of the faulted loops were measured to be 2.3 X 1016 cm-3 and 8.4 nm, respectively. There are fine precipitates distributed in 800H with an average size approximately 6 nm and a density greater than 9.1 X 1015 cm-3. The high Ni content and the presence of precipitates are believed to be responsible for the resistance to void formation at dose up to 50 dpa.

Since the fissile and transuranic (TRU) elements in the spent nuclear fuel present a proliferation risk, limit the repository capacity, and are the major contributors to the long-term toxicity and dose from the repository, methods and systems are needed to reduce the amount of TRU that will eventually require long-term storage. An option to achieve a reduction in the amount, and modify the isotopic composition of TRU requiring geological disposal is 'burning'the TRU in commercial light water reactors (LWRs) and/or fast reactors. Fuel forms under consideration for TRU destruction in light water reactors (LWRs) include mixed-oxide (MOX), advanced mixed-oxide, and inert matrix fuels. Fertile-free inert matrix fuel (IMF) has been proposed for use in many forms and studied by several researchers. IMF offers several advantages relative to MOX, principally it provides a means for reducing the TRU in the fuel cycle by burning the fissile isotopes and transmuting the minor actinides while producing no new TRU elements from fertile isotopes. This paper will present and discuss the results of a four-bundle, neutronic, thermal-hydraulic, and transient analyses of proposed inert matrix materials in comparison with the results of similar analyses for reference UOX fuel bundles. The results of this work are to be used for screening purposes to identify the general feasibility of utilizing specific inert matrix fuel compositions in existing and future light water reactors. Compositions identified as feasible using the results of these analyses still require further detailed neutronic, thermal-hydraulic, and transient analysis study coupled with rigorous experimental testing and qualification.

This new design minimizes soil packing difficulties and potential bias in water and solute flow pathways commonly associated with rigid probe installations in column experiments. Tests demonstrated that the modified flexible electrode design maintains a voltage response that is proportional to the electrode trace length and is reduced by approximately one-half when only one side of the electrode trace is in contact with the soil media. Laboratory experiments confirmed that the longer electrode traces attached to the interior of a column wall have a comparable sensitivity of that of a commercially available rigid probe inserted horizontally across the diameter of a soil column. The replacement of the rigid electrode with a flexible electrode offers an improved method of measuring the water content in solute transport experiments while minimizing sensor intrusion into laboratory soil columns.

We have been investigating the potential for stimulating microbially mediated urea hydrolysis to promote the precipitation of calcium carbonate and the co-precipitation of trace metals as a method for treating 90Sr -contaminated systems. Urea hydrolysis results in an increase in both pH and carbonate alkalinity, and these factors can promote carbonate mineral precipitation. The ability to hydrolyze urea is widespread among subsurface microorganisms, and therefore remediation schemes based upon this approach could rely on indigenous organisms. In environments that favor calcite stability, which includes many aquifers in the western United States, this approach could result in long-term stabilization of the contaminants. Development of this concept into a practical remediation approach requires that we be able to control where precipitation occurs and at what rate. This requires a better understanding of the controls on the spatial distributions of mineral precipitation and the ureolysis reactions. A particular challenge is to understand how the system permeability and fluid flow changes over time, which is coupled to the precipitation rates and distribution of the precipitate. As part of our efforts to study these coupled processes, we are testing the application of complex resistivity (CR) as a means of mapping the distribution of precipitated calcite in a porous media column. CR measurements are sensitive to and are affected by chemical surface properties, porosity, grain size, and pore space distribution, and therefore we anticipate that mineral precipitation within the column will be detectable by CR. In this presentation we will report on our preliminary efforts to characterize the CR response within a porous media column where calcite precipitation is induced by extracellular ureolysis.

Rates of dissolution of different classes of surface features (e.g., steps, voids, and dislocation etch pits) were measured. The prismatic surface etched almost two orders of magnitude faster than the rhombohedral surface, mostly due to the difference in the number and the rate of dissolution of extended defects, such as dislocations. Because of the presence of imperfect twin boundaries, defect densities on the prismatic surface were estimated at 50-100 mu m (super -2) , whereas the rhombohedral surface possessed only approximately 0.5-1.0 mu m (super -2) , mostly in the form of crystal voids. Crystal voids etched almost one order of magnitude faster on the prismatic surface than on the rhombohedral surface due to differences in the number and the density of steps formed by voids on the different surfaces. In the absence of extended defects, both surfaces underwent step-wise dissolution at similar rates. Average rates of step retreat were comparable on both surfaces ( approximately 3-5 nm/h on the prismatic surface and approximately 5-10 nm/h on the rhombohedral surface). Prolonged dissolution left the prismatic surface reshaped to a hill-and-valley morphology, whereas the rhombohedral surface dissolved to form coalescing arrays of oval-shaped etch pits.

The process chemistry is unique and complicated, since the extractants, chlorinated cobalt dicarbollide (CCD), polyethylene glycol (PEG), and diphenyl-N,N-di-n-butylcarbamoylmethylphosphine oxide (Ph sub(2)CMPO), operatesynergistically to extract the major radionuclides.A combination of classical chemistry techniques, infrared (IR) spectroscopy, and nuclear magnetic resonance (NMR) spectroscopy were utilized to identify and explain the structures formed in the organic phase with protons or metal ions. Model systems, CCD-PEG and CCD-bidentate organophosphorus compounds were studied and possible structures of complexes, existing in the organic phase, are proposed and properties of the UNEX extractant are discussed.

AN - 67766251; 16544889 AB - A relatively simple and cost-effective method utilizing HPLC with UV detection was developed to detect and quantify hydrazine in sludge samples. The method was developed primarily for sludge samples, but it can also be applicable to soil and other environmental samples. The hydrazines in the matrices were derivatized to hydrazones with benzaldehyde. The hydrazones were separated using HPLC with an RP C-18 column in an isocratic mode with methanol-water (95:5 v/v) and detected with UV detection at 313 nm. The detection limit (25 microL injection) for the method is 0.02 microg/mL of hydrazine.

Several examples in the literature show that geosynthetic clay liners can withstand a limited number of freeze-thaw events, but data on long-term freeze-thaw performance are lacking. The objective of this study was to examine the long-term performance of geosynthetic clay liners exposed to repeated freeze-thaw cycles, encompassing their application as a final cover as well as a bottom liner. Measurements of hydraulic conductivity were performed after as many as 150 freeze-thaw cycles, with no appreciable increases observed.

We report here the vertical and geographical distribution of microbes and their phylogenetic diversities in deeply buried marine sediments of the Pacific Ocean Margins. During the Ocean Drilling Program Legs 201 and 204, we obtained sediment cores from the Peru and Cascadia Margins that varied with respect to the presence of dissolved methane and methane hydrate. To examine differences in prokaryotic distribution patterns in sediments with or without methane hydrates, we studied >2,800 clones possessing partial sequences (400-500 bp) of the 16S rRNA gene and 348 representative clone sequences ( approximately 1 kbp) from the two geographically separated subseafloor environments. Archaea of the uncultivated Deep-Sea Archaeal Group were consistently the dominant phylotype in sediments associated with methane hydrate. Sediment cores lacking methane hydrates displayed few or no Deep-Sea Archaeal Group phylotypes. Bacterial communities in the methane hydrate-bearing sediments were dominated by members of the JS1 group, Planctomycetes, and Chloroflexi. Results from cluster and principal component analyses, which include previously reported data from the West and East Pacific Margins, suggest that, for these locations in the Pacific Ocean, prokaryotic communities from methane hydrate-bearing sediment cores are distinct from those in hydrate-free cores. The recognition of which microbial groups prevail under distinctive subseafloor environments is a significant step toward determining the role these communities play in Earth's essential biogeochemical processes.

The key characteristics of the platform architecture are that the platform is passive until externally energized--no internal power source is required--and that it communicates with a "reader" via short-range telemetry--no wires penetrate the subsurface. Other significant attributes include the potential for a long service life and a compact size that makes it well suited for retrofitting existing landfill structures. Functionally, the sensor package is "read" by a short-range induction coil that activates and powers the sensor platform as well as detects the sensor output via a radio frequency signal generated by the onboard programmable interface controller microchip. As a result, the platform has a functional subsurface communication range of approximately 10 to 12 ft. and can only accept sensors that require low power to operate.

Based on the scaling laws of centrifuge modeling, the measurements generally showed reasonable agreement with prototype data calculated from forward simulations with input parameters determined from standard laboratory tests. The parameter optimizations were examined for three different combinations of input data sets using the test measurements. Within the gravity level examined in this study up to 40g, the optimized unsaturated parameters compared well when accurate pore water pressure measurements were included along with cumulative outflow as input data. With its capability to implement variety of instrumentations under well controlled initial and boundary conditions and to shorten testing time, the centrifuge modeling technique is attractive as an alternative experimental method that provides more freedom to set inverse problem conditions for the parameter estimation.

The design contains many innovative features to improve both the physics and engineering performance of the system. From the safety and environmental perspective, there is greater depth to the overall analysis than in past ARIES studies. For ARIES-AT, the overall spectrum of off-normal events to be examined has been broadened. They include conventional loss of coolant and loss of flow events, an ex-vessel loss of coolant, and in-vessel off-normal events that mobilize in-vessel inventories (e.g., tritium and tokamak dust) and bypass primary confinement such as a loss of vacuum and an in-vessel loss of coolant with bypass. This broader examination of accidents improves the robustness of the design from the safety perspective and gives additional confidence that the facility can meet the no-evacuation requirement under average weather conditions. We also provide a systematic assessment of the design to address key safety functions such as confinement, decay heat removal, and chemical energy control. In the area of waste management, both the volume of the component and its hazard are used to classify the waste. In comparison to previous ARIES designs, the overall waste volume is less because of the compact design.

However, recent threats to our nation's critical infrastructure have prompted a tightening of security measures across many different industry sectors. Reducing control system vulnerabilities against physical and cyber attack is necessary to ensure the safety, reliability, integrity, and availability of these systems. The U.S. Department of Homeland Security has developed a strategy to secure these vulnerabilities. Crucial to this strategy is the Control Systems Security and Test Center (CSSTC) established to test and analyze control systems and their components. In addition, the CSSTC promotes a proactive, collaborative approach to increase industry's awareness of standards, products, and processes that can enhance the security of control systems. This paper outlines measures that can be taken to enhance the cybersecurity of process control systems in the chemical sector.

The internal configuration of the models ranged in complexity from simple geometric shapes to those that incorporate replicated surfaces of natural fractures and computationally derived fracture surfaces. High-resolution digital time-lapse imaging was employed to qualitatively observe the migration of colloidal and soluble dyes through the flow models. In this study, a Sphingomonas sp. and Sporosarcina (Bacillus) pasteurii influenced the fluid dynamics by physically altering flow paths. Microbial colonization and calcite deposition enhanced the stagnant regions adjacent to solid boundaries. Microbial growth and calcite precipitation occurred to a greater extent in areas behind the fabricated obstacles and less in high-velocity orifices.

The aim of this chapter is to describe a social network analysis (SNA) application by providing a framework for its use in a process-based program evaluation to assess knowledge capacity. This case study involved surveying all thirty-eight program members who were working on the hydrogen initiative, using SNA to analyze the survey results, & then asking a focus group of staff members to explain & comment on the network analysis results. Three general indicators were used to assess the knowledge capacity of the Hydrogen Initiative Program: expert selection, frequency of selection, & connectedness. Figures, References.

This study was undertaken to determine if there are significant differences between bulk and rhizosphere soils from the Idaho National Laboratory (INL) with respect to their ability to bind Cs. The capacity of FES on bulk and rhizosphere soil materials and conditional Cs/K selectivity of FES ( (super c) K (sub ex) (super FES) ) were determined as a function of both soil type and initial exchanger composition. The FES capacity was significantly higher in untreated, Ca-saturated, and K-saturated rhizosphere soil materials as compared with bulk soil materials. Sorption-desorption isotherms were obtained at Cs concentrations between 5 X 10 (super -9) and 5 X 10 (super -6) M. No difference in Cs sorption was observed between bulk and rhizosphere soil materials. The composition of the exchanging solution had the greatest effect on the magnitude of Cs desorption; significantly more Cs was desorbed in the presence of KCl than in either CaCl (sub 2) or a mixed-cation soil solution. In addition, Cs desorption was greater from rhizosphere soil materials relative to bulk soil materials. Cesium selectivity with respect to both Ca and K was significantly suppressed by weathering in the rhizosphere. We conclude that enhanced weathering in the rhizosphere increased the Cs sorption capacity of FES, but also reduced Cs selectivity on these sites. Enhanced Cs desorption from rhizosphere INL soils is likely in the presence of actively growing plants and associated microorganisms.

The benchmarks had no measurable displacement relative to one another during the nine-year study, evidence that the ESRP behaves as a rigid, non-extending block at the resolution of the GPS. This conclusion is supported by the aseismic nature of the province and the lack of measurable horizontal stress in boreholes. Motion of the ESRP away from the stable craton is apparently accommodated by extension of the Yellowstone Plateau, which is part of a parabolic belt of high seismicity that extends into parts of the Basin and Range and surrounds the ESRP. The velocity of the ESRP measured in this study, combined with the North American Plate velocity, is sufficient at first order to account for the approximately 290 km chain of silicic calderas created by the Yellowstone hotspot over the past 10 my. However, an additional small component of intra-plain extension must also be invoked to account for the NW-trending volcanic rift zones that transect the plain. We suggest that intra-plain extensional elastic strain accumulates at a rate that is too slow (<10-16 s-1) to measure using GPS over decadal time scales, but is sufficient over millennial time scales to require dike injection and consequent rift zone formation. Three additional GPS benchmarks in the Basin and Range Province immediately north of the ESRP moved in a similar direction to ESRP stations but at slightly slower rates (1.5 to 2.3 mm/yr). If these limited data are representative, the velocity difference between the two provinces may be accommodated by a previously unrecognized diffuse transfer zone.

It is a zone where the system of NNW-trending range-bounding faults to the north is juxtaposed to the low topographic expression of the volcanic providence to the south. The NNW-trending normal faults have trace lengths approaching 150 km and throws ranging between 5.5 to 2.5 km. The northern and central segments are seismically active, but the activity is reduced as the ESRP is approached toward the south. In the ESRP, only modest seismicity is recorded and deformation is associated with NNW-trending volcanic rift zones that result from basalt dike intrusion since the northeasterly passage of the Yellowstone Hotspot between 6 to 4 Ma. The age distribution of basalt volcanism along the southern termination of Basin and Range faults is inconsistent with active accommodation of normal fault slip into the ESRP either by brittle displacement or by along-strike dike emplacement. Geologic and geophysical relations in the Little Lost River basin, adjacent to the southern segment of the Lemhi Fault suggest basin segmentation by ENE-trending transfer faults that control the polarity of the fault bound basin. The transfer fault intersects the Lemhi Fault near the location of a 3.5 km wide left step where the range-front fault experiences a step that corresponds to a decrease in range height of 900 m and a major reduction of scarp elevations to the south. As the ESRP is approached, the half-graben bound fault is transferred from the eastern to western sides of the basin and the transfer fault served as a boundary that prevented basalt from reaching the basin segment farther north. The local development of the Lemhi transfer fault system may serve as a small analog for a transtensional basin system marking the boundary between Basin and Range structures and the ESRP. The age of basalt flows together with localized development of thick sedimentary accumulation along the ENE-trending boundary zone suggest that normal fault slip on Basin and Range faults was transferred to localized basaltic volcanic rift zones whose periods of activity migrated southward along the northwestern margin of the ESRP over the last several million years.

Healthy plant communities are critical to the success and effectiveness of these vegetated landfill covers. Poor vegetative cover can result in reduced transpiration, increased percolation, and increased erosion regardless of the thickness of the cover. Visual inspections of landfill covers indicate that vegetation-free areas are not uncommon at municipal waste landfills. Data from soil profiles beneath these areas suggest that anaerobic conditions in the plant-rooting zone are controlling plant distribution. On the same landfill, aerobic conditions exist at similar depths beneath well-vegetated areas. The movement of methane and carbon dioxide, generated by degradation of organic wastes, into the overlying soil cover displaces oxygen in the root zone. Monitoring data from landfills in semi-arid areas indicate that barometric pumping can result in hours of anaerobic conditions in the root zone. Microbial consumption of oxygen in the root zone reduces the amount of oxygen available for plant root respiration but consumption of oxygen and methane also produce water as a reaction byproduct. This biogenic water production can be on the order of centimeters of water per year which, while increasing water availability, also has a negative feedback on transport of landfill gases through the cover. Accounting for these processes can improve evapotranspirative landfill cover design at other sites. In this study, we attempt to quantify gas consumption/production rates in the root zone above a landfill through inverse modeling of a high-resolution, multilevel, multicomponent gas monitoring system installed in the landfill cover.

This interest arises largely from the increased driving force for unsaturated flow using the centrifuge and the potential for completing relevant vadose zone experiments in less time than that required when using conventional 1-gravity techniques. To fully realize the potential of centrifuge experimental approaches, equations of fluid flow in a variable centrifugal field have been derived and are compared to equations in a constant 1-gravity field. We have derived an expression for fluid potential under conditions where centripetal and gravitational accelerations are significant. In addition, we show from the Navier-Stokes equations applied to porous media flows within a geocentrifuge the relative effects that a variable gravity field, represented by the centripetal force and the coriolis force, have on the flow fields. Nondimensionalization of the governing equations shows the role that the Ekman and Rossby numbers play in these porous media flows. This analysis provides information useful for the scaling of variable gravity geocentrifuge experiments and helps to define the theoretical limits under which geocentrifuge experiments exhibit similarity to field phenomena.

Early in the cap design EPA recognized the need for a long-term monitoring system which should meet the following objectives: 1, Provide information on the integrity of the newly constructed surface cover and diversion system; 2, Continually assess the waste's hydrological and geochemical behavior, such that rational decisions can be made for the operation of this cap and liner system; 3, Provide easy access to information pertaining to the system performance to stakeholders; 4, Integrate of a variety of data sources to produce information which could be used to enhance future cap designs. Through discussions between EPA, and Idaho National Laboratory a long-term monitoring system was designed and implemented allowing EPA to meet these objectives. This system is implemented as a web based workflow environment, and provides a cost effective manner to deal with massive amounts of data and information. The monitoring system integrates data from a set of 522 electrodes resistivity electrodes consisting of 462 surface electrodes and 60 borehole electrodes (in 4 wells with 15 electrodes each), an outflow meter at the toe of the repository, an autonomous, remotely accessible weather station, and four wells (average depths of 250 feet) with thermocouples, pressure transducers and sampling ports for water and air. The monitoring system has currently been in operation for over two years, and has collected data continuously over this period. Results from this system allow for autonomous performance monitoring through automated data analysis and report generation. Performance monitoring has allowed users to obtain insights into the diurnal variation in rockmass behavior, movement of water through the waste (allowing estimates on residence time) and is leading to a comprehensive model of repository behavior. The same infrastructure and approach has been applied to other sites, and can be extended to performance monitoring of natural attenuation and other passive remedial systems.

For this work we estimated the in situ methane production rates in Hydrate Ridge (HR) sediments by coupling experimentally derived minimal rates of methanogenesis to methanogen biomass determinations for discrete locations in the sediment column. When starved in a biomass recycle reactor Methanoculleus submarinus produced ca. 0.017 fmol methane/cell/day. A real time polymerase chain reaction assay that targeted the methanogen-specific mcr gene indicated that 75% of the HR samples analyzed contained <100 methanogens/g of sediment. Samples with higher numbers of methanogens were either from sediments <10 meters below seafloor or from a few deeper locations that appeared to be associated with notable geological features such as the boundary of gas hydrate and free gas (known as the bottom-simulating reflector or BSR), and an ash-bearing zone with high fluid movement. Acetate concentrations in sample porewaters ranged from 3.17 to 2515 mM with the highest concentrations measured just above the BSR at a control site relative to HR. Locally high concentrations of acetate were evident at all BSRs, and often corresponded with gas hydrate presence. High acetate concentrations sometimes corresponded with low methanogen biomass. Acetate concentrations were typically lowest near the seafloor. Porewater hydrogen concentrations ranged from 16.45 to 1036 parts per million by volume (ppmv). Sometimes hydrogen and acetate concentrations were elevated concurrently. By combining methanogenesis rates for starved cells and the numbers of methanogens at selected depths we derived a maximum estimate of 1.7 X 10 (super -6) nmol methane produced/g sediment/day where methanogens could not be detected, a rate lower than previous methanogenic rate estimates in hydrate-bearing sediments. Where methanogen numbers are higher the rates may exceed 7.4 X 10 (super -2) nmol methane produced/g sediment/day. These data will improve models intended to predict the location of hydrates in marine sediments, the amount of biogenic gas that can accumulate in the sediments, and the potential influence that this microbially-mediated source of methane has on the global carbon cycle.

Subsoil was placed experimentally in 1993 into field trenches to simulate waste burial by soil caps in the semiarid western USA, planted, and sampled in 2001 to investigate rates of enrichment of surface soil with organic C and available P in relation to plant canopies. Various soil cap designs and irrigation regimens were studied. Under ambient moisture levels, organic C in the surface soil below Wyoming big sagebrush Artemisia tridentata wyomingensis Beetle & Young increased annually at an average rate of 0.5 g kg (super -1) . We estimate 32 yr would be needed for exposed subsoil to increase to the level of soil surface organic C below sagebrush in undisturbed steppe. Soil surface bicarbonate-available P increased under ambient moisture inputs below sagebrush at a rate of 3.6 mu g g (super -1) annually and had after 8 yr advanced more than half way from levels in exposed subsoil to those in established steppe. Irrigation stimulated enrichment of organic C and available P, and annual rates of increase across the experiment were 0.9 g kg (super -1) for C and 6 mu g g (super -1) for P. Cap design effects were mostly absent. Enrichment of surface organic C and available P below shrub canopy, compared with intercanopy space, was evident in both the experimental and undisturbed plots. Corresponding increases in C and P were less pronounced under bunchgrass canopies.

The most promising stabilization technologies include mineralization via biochemical amendments. Practical application of these amendments requires accurate site characterization, optimal delivery, and detailed process monitoring. There are a variety of biochemical amendments being investigated at the INL, and across the scientific community. However, capitalizing on these advances will require the ability to design, deliver, and monitor the processes. We present an experimental plan for investigating application and delivery mechanisms for Strontium-90 in situ stabilization in porous media interspersed between layers of fractured basalt underlying the Idaho National Laboratory (INL) near Idaho Falls, Idaho. Additionally, we will present results of initial site characterization during which subsurface monitoring captured infiltration from a nearby ephemeral river that flowed for ten days in June 2005. The recharge event provides insight into the formation, redistribution, and longevity of perched water zones that form in complex, heterogeneous vadose zones. The transport behavior captured during this recharge event demonstrates the inherent challenges associated with delivering contaminant stabilization amendments to target regions of the vadose zone at the INL. Data collected during the characterization event included traditional hydrological data such as water potential, water content, and perched water pressures, in addition to three-dimensional time-lapsed electrical resistivity tomography. The experimental plan outlines the use of a joint inversion methodology developed at INL for coupled data analysis.

Other landfill caps with 30 year design lifetimes are reaching the end of their original design life; the changes to these caps need to be understood to provide a basis for lifetime extension. Defining the attributes that make a successful cap (one that isolates the waste from the environment) is crucial to these efforts. Because cap systems such as landfill caps are dynamic in nature, it is impossible to understand, monitor, and update lifetime predictions without understanding the dynamics of cap degradation, which is most often due to multiple interdependent factors rather than isolated independent events. In an attempt to understand the dynamics of cap degradation, a computer model using system dynamics is being developed to capture the complex behavior of an evapotranspiration cap. The specific objectives of this project are to capture the dynamic, nonlinear feedback loop structures underlying an evapotranspiration cap and, through computer simulation, gain a better understanding of long-term behavior, influencing factors, and, ultimately, long-term cap performance.

This workflow environment integrates distributed automated data acquisition with server side data management and information visualization through flexible browser-based data access tools. Component technologies include a rich browser-based client, a back-end server for methodical data processing, user management, and result delivery, and third party applications which are invoked by the back-end using web services. This environment allows for reproducible, transparent result generation by a diverse user base, and provides a seamless integration between data selection, analysis applications, and result delivery. This workflow system has been implemented for several sites and monitoring systems with different degrees of complexity.

AN - 67946000; 15894485 AB - Our laboratory has purchased four LaCl (3)(Ce) scintillation crystals over the course of the last year for evaluation as part of an environmental management research and development project. In addition to the expected content of naturally radioactive (138)La, we have found that all four of these detectors are contaminated to various degrees with alpha particle emitting nuclides that we have determined to be (227)Ac and its daughters. The impact of these radionuclides on the background spectra and, thus, on the detection sensitivity of these detectors is presented and discussed.

The SPH is a fully Lagrangian particle-based method that allows the dynamics of interfaces separating fluids to be modeled without employing complex front tracking schemes. In SPH simulations, the fluid density field is represented by a superposition of weighting functions centered on particles which represent the fluids. The pressure is related to the fluid density through an equation of state, and the particles move in response to the pressure gradient. The SPH does not require the construction of grids that would otherwise introduce numerical dispersion. The model can be used to simulate complex free-surface flow phenomenon such as invasion of wetting and nonwetting fluids into three-dimensional fractures. These processes are a severe challenge for grid-based methods. Surface tension was simulated by using a van der Waals equation of state and a combination of short-range repulsive and longer-range attractive interactions between fluid particles. The wetting behavior was simulated using similar interactions between mobile fluid particles and stationary boundary particles. The fracture geometry was generated from self-affine fractal surfaces. The fractal model was based on a large body of experimental work, which indicates that fracture surfaces have a self-affine fractal geometry characterized by a material independent (quasi universal) Hurst exponent of about 0.75.

Most investigations into the effect of DMRB on sediment geochemistry utilize various synthetic oxides as the Fe super(III) source (e.g. ferrihydrite, goethite, hematite). These synthetic materials do not represent the mineralogical composition of natural systems, and do not account for the effect of sediment mineral composition on microbially mediated processes. Our experiments with a DMRB (Shewanella putrefaciens 200) and a divalent metal (Zn super(II)) indicate that, while complexity in sediment mineral composition may not strongly impact the degree of "microbial iron reducibility, " it does alter the geochemical consequences of such microbial activity. The ferrihydrite and clay mineral content are key factors. Microbial reduction of a synthetic blend of goethite and ferrihydrite (VHSA-G) carrying previously adsorbed Zn super(II) increased both [Zn super(II)-aq] and the proportion of adsorbed Zn super(II) that is insoluble in 0.5 M HCl. Microbial reduction of Fe super(III) in similarly treated iron-bearing clayey sediment (Fe-K-Q) and hematite sand, which contained minimal amounts of ferrihydrite, had no similar effect. Addition of ferrihydrite increased the effect of microbial Fe super(III) reduction on Zn super(II) association with a 0.5 M HCl insoluble phase in all sediment treatments, but the effect was inconsequential in the Fe-K-Q. Zinc k-edge X-ray absorption spectroscopy (XAS) data indicate that microbial Fe super(III) reduction altered Zn super(II) bonding in fundamentally different ways for VHSA-G and Fe-K-Q. In VHSA- G, ZnO sub(6) octahedra were present in both sterile and reduced samples; with a slightly increased average Zn-O coordination number and a slightly higher degree of long-range order in the reduced sample. This result may be consistent with enhanced Zn super(II) substitution within goethite in the microbially reduced sample, though these data do not show the large increase in the degree of Zn-O- metal interactions expected to accompany this change. In Fe-K-Q, microbial Fe super(III) reduction transforms Zn-O polyhedra from octahedral to tetrahedral coordination and leads to the formation of a ZnCl sub(2) moiety and an increased degree of multiple scattering. This study indicates that, while many sedimentary iron minerals are easily reduced by DMRB, the effects of microbial Fe super(III) reduction on trace metal geochemistry are dependent on sediment mineral composition.

Structural analysis of wheat stem cross-sections was performed using the theory of composites and finite element analysis techniques. Representative geometries of the stem's structural components including the hypoderm, ground tissue, and vascular bundles were established using microscopy techniques. Material property data for the analysis was obtained from measured results. Results from the isotropic structural analysis model were compared with experimental data. Future work includes structural analysis and comparison with experimental results for additional wheat stem models and loading configurations.

Several testing methods--compression, tension, and bend--were investigated to increase the understanding of the biomechanical behavior of cellulosic feedstocks. Biomechanical data from these tests can provide required input to numerical models and help advance harvesting, handling, and processing techniques. In addition, integrating the models with the complete data set from this study can identify potential tools for manipulating the biomechanical properties of plant varieties in such a manner as to optimize their physical characteristics to produce higher-value biomass and more energy-efficient harvesting practices.

It was also the first time that (1) digital infrared scans of core temperature were systematically recorded for all cores from within or near the gas hydrate stability zone, facilitating identification of gas hydrate samples for further study, (2) hydrate-bearing cores were recovered and logged at in situ pressure, and (3) ODP allowed acquisition of logging-while-drilling data prior to coring at a given site, providing an initial comprehensive estimate of gas hydrate distribution that was used to design the subsequent coring program. Gas hydrate estimates based on a variety of geophysical and geochemical techniques indicate a heterogeneous distribution of gas hydrate, which results in part because of two distinct regimes for delivery of gas to the gas hydrate stability zone. In the "reaction regime," which is pervasive throughout the study region, the average gas hydrate content of the sediments is relatively low (2%-8% of the pore space), no gas hydrate is present in the upper approximately 30 meters below seafloor (mbsf) because the methane content of the pore water is below saturation, and the fine-scale distribution of gas hydrate depends strongly on lithology. Superimposed on the reaction regime is a "transport-dominated regime" in which gas is focused into a stratigraphically controlled conduit and is transported as free gas to the structural summit. At the summit, high gas pressure drives free gas into and through the gas hydrate stability zone, resulting in a shallow deposit in which gas hydrate comprises approximately 25% of the total sediment volume to a depth of approximately 25 mbsf. Geochemical data indicate that most of the gas that forms the summit deposit has migrated from greater depth and has either a thermogenic or altered biogenic character, and modeling suggests that abundant free gas is needed to form gas hydrate in these conditions. Although this deposit contains only approximately 2% of the estimated total volume of methane trapped in gas hydrate within the study region, it may be particularly susceptible to destabilization in response to oceanographic change.

Acetate concentrations ranged from 3.17 to 2515 mu M. The maximum acetate concentrations occurred at Site 1251, which was drilled on a slope basin to the east of SHR at depths just above the bottom- simulating reflector (BSR) that marks the boundary of gas hydrate stability. Acetate maxima and localized high acetate concentrations occurred at the BSR at all sites and frequently corresponded with areas of gas hydrate accumulation, suggesting an empirical relationship. Acetate concentrations were typically at a minimum near the seafloor and above the sulfate/methane interface, where sulfate-reducing bacteria may consume acetate. Hydrogen concentrations in pressure core samples ranged from 16.45 to 1036 parts per million by volume (ppmv). In some cases, hydrogen and acetate concentrations were elevated concurrently, suggesting a positive correlation. However, sampling of hydrogen was limited in comparison to acetate, so any relationships between the two analytes, if present, were difficult to discern.

Interactions of U(VI) and hydrous iron oxide moieties on the mineral oxide surfaces were studied during enrichments for dissimilatory iron reducing (DIRB) and sulfate reducing bacteria (SRB). Microbes enriched from groundwater taken from the Test Area North (TAN) site at the Idaho National Laboratory (INL) were able to reduce the U(VI) in the adsorption medium as well as the iron on quartz surfaces. Early in the experiment disappearance of U(VI) from solution was a function of chemical interactions since no microbial activity was evident. Abiotic removal of U(VI) was enhanced in the presence of carbonate. As the experiment proceeded, further removal of U(VI) from solution was associated with the fermentation of lactate to propionate and acetate. During later phases of the experiment when lactate was depleted from the growth medium in the microcosm containing the DIRB enrichments, U(VI) concentrations in the solution phase increased until additional lactate was added. When additional lactate was added and fermentation proceeded, U(VI) concentrations in the liquid phase again returned to near zero. Similar results were shown for the SRB enrichment but lower uranium concentrations were seen in the liquid phase, while in the enrichment with carbonate a similar increase in uranium concentration was not seen. Chemical and biological interactions appear to be important on the mobilization/immobilization of U(VI) in an iron oxide system when TCE is present as a co-contaminant. Interestingly, TCE present in the microcosm experiments was not dechlorinated which was probably an effect of redox conditions that were unsuitable for reductive dechlorination by the microbial culture tested.

The combination of air, high moisture, and high microbial loads leads to shrinkage during storage and risk of spontaneous ignition. Ensiling is a wet preservation method that could be used to store these residues stably. To economically adapt ensiling to biomass that is harvested after it has senesced, the need for nutrient, moisture, and microbial additions must be determined. We tested the ensiling of senesced wheat straw in sealed columns for 83 d. The straw was inoculated with Lactobacillus plantarum and amended with several levels of water and free sugars. The ability to stabilize the straw polysaccharides was strongly influenced by both moisture and free sugars. Without the addition of sugar, the pH increased from 5.2 to as much as 9.1, depending on moisture level, and losses of 22% of the cellulose and 21% of the hemicellulose were observed. By contrast, when sufficient sugars were added and interstitial water was maintained, a final pH of 4.0 was attainable, with correspondingly low (<5%) losses of cellulose and hemicellulose. The results show that ensiling should be considered a promising method for stable storage of wet biorefinery feedstocks.

One promising technology is the sequestration of CO2 in geologic formations. The suitability of a fractured basalt reservoir for CO2 sequestration is constrained by three broad categories of issues, which we refer to as physical, technical, and economic constraints. Physical constraints are beyond human control; thus, it is a requirement that a systematic method be developed by which a particular target reservoir may be evaluated to determine if it lies within the bounds required for safe and effective disposal. Technical constraints, on the other hand, are challenges to the ability to design, construct, and/or monitor a sequestration project as a result of limitations on our ability to determine the distribution of properties in the subsurface, our knowledge of the behavior of CO2 in the deep subsurface, and the current state of computational science and subsurface monitoring. Equally important are the heterogeneity of economic costs associated with sequestering CO2 at different sites and within different formations. The work presented here focuses on the technical aspects of CO2 injection, specifically examining reactive transport of CO2 in the subsurface in the vicinity of the injection well using the simulation code TOUGHREACT. Pressure distribution and propagation, kinetics of the geochemical reactions, and resultant changes in permeability/porosity are examined in order to evaluate injection scenarios that maximize the longevity of the injection well and sustainability of the reservoir.
