TY - JOUR T1 - Quantifying the local influence at a tall tower site in nocturnal conditions AN - 1868302294; PQ0004063735 AB - The influence of the local terrestrial environment on nocturnal atmospheric CO sub(2) measurements at a 329-m television transmitter tower (and a component of a CO sub(2) monitoring network) was estimated with a tracer release experiment and a subsequent simulation of the releases. This was done to characterize the vertical transport of emissions from the surface to the uppermost tower level and how it is affected by atmospheric stability. The tracer release experiment was conducted over two nights in May of 2009 near the Department of Energy's Savannah River Site (SRS) in South Carolina. Tracer was released on two contrasting nights-slightly stable and moderately stable-from several upwind surface locations. Measurements at the 329-m level on both nights indicate that tracer was able to mix vertically within a relatively short (24 km) distance, implying that nocturnal stable conditions do not necessarily prevent vertical dispersion in the boundary layer and that CO sub(2) measurements at the tower are at least partly influenced by nearby emissions. A simulation of the tracer release is used to calculate the tower footprint on the two nights to estimate the degree to which the local domain affects the tower readings. The effect of the nocturnal boundary layer on the area sampled by the tower can be seen clearly, as the footprints were affected by changes in stability. The contribution of local sources to the measurements at the tower was minimal, however, suggesting that nocturnal concentrations at upper levels are contributed mostly by regional sources.

While the effects of fire on carbon cycle have been measured in previous studies for short periods during a burn and for multiyear periods following the burn, information on how carbon cycle is influenced by such changes over the span of a few weeks to months has yet to be quantified. We have analyzed high-frequency measurements of CO sub(2) concentration and flux, as well as associated micrometeorological variables, at three levels of the tall Aiken AmeriFlux tower during and after a prescribed burn. Measurements of the CO sub(2) concentration and vertical fluxes were examined as well as calculated net ecosystem exchange (NEE) for periods prior to and after the burn. Large spikes in both CO sub(2) concentration and CO sub(2) flux during the fire and increases in atmospheric CO sub(2) concentration and reduced CO sub(2) flux were observed for several weeks following the burn, particularly below the forest canopy. Both CO sub(2) measurements and NEE were found to return to their preburn states within 60-90days following the burn when no statistical significance was found between preburn and postburn NEE. This study examines the micrometeorological conditions during a low-intensity prescribed burn and its short-term effects on local CO sub(2) dynamics in a forested environment by identifying observable impacts on local measurements of atmospheric CO sub(2) concentration and fluxes. Key Points * The impacts of prescribed fire on local carbon cycle are not limited to the period of fire but may extend several weeks beyond the fire * Micrometeorological impacts were limited to 1-2days or less, but the impacts to the CO sub(2), particularly to the flux of CO sub(2), lasted longer * Large initial changes in the net ecosystem exchange between the preburn and postburn periods were no longer observed 60-90days following JF - Journal of Geophysical Research.

Injection as aerosols in a carrier gas could be a viable method for achieving useful distributions of amendments in unsaturated materials. The objectives of this work were to characterize radial transport of aerosols in unsaturated porous media, and to develop capabilities for predicting results of aerosol injection scenarios at the field-scale. Transport processes were investigated by conducting lab-scale injection experiments with radial flow geometry, and predictive capabilities were obtained by developing and validating a numerical model for simulating coupled aerosol transport, deposition, and multi-phase flow in porous media. Soybean oil was transported more than 2 m through sand by injecting it as micron-scale aerosol droplets. Oil saturation in the sand increased with time to a maximum of 0.25, and decreased with radial distance in the experiments. The numerical analysis predicted the distribution of oil saturation with only minor calibration. The results indicated that evolution of oil saturation was controlled by aerosol deposition and subsequent flow of the liquid oil, and simulation requires including these two coupled processes. The calibrated model was used to evaluate field applications. The results suggest that amendments can be delivered to the vadose zone as aerosols, and that gas injection rate and aerosol particle size will be important controls on the process.

We assessed the heterogeneity among fish assemblages in first- to fourth-order stream sites from four river basins (Savannah, Chattahoochee, Cape Fear, and Pee Dee rivers) within the Sand Hills ecoregion of the southeastern USA and compared it with the heterogeneity associated with watershed and stream reach spatial scales. Fifty-five species of fish representing 15 families were collected by electrofishing, with the most speciose families being Cyprinidae, Centrarchidae, Percidae, Ictaluridae, and Catostomidae. Constrained ordination identified clearly demarcated species assemblages among river basins as well as subbasin environmental variables that affected fish species composition; the amounts of variance attributable to basin, watershed, and stream reach spatial scales were roughly equivalent. Prominent differences occurred between Gulf of Mexico coast and Atlantic coast river basins, but differences among Atlantic coast basins were also apparent. Key variables at the watershed scale included watershed size, relief, extent of anthropogenic disturbance, and forest cover; key variables at the stream reach scale included instream habitat quality, proximity to a larger stream, and stream width. Fish assemblage collective and functional properties were more strongly influenced by variables acting at watershed and stream reach spatial scales than by differences among basins. Species richness peaked at intermediate levels of habitat quality as a likely result of biotic homogenization, indicating that the least disturbed sites within the region do not necessarily possess the highest species richness. Failure to consider this may lead to the overrating of moderately disturbed sites and the underrating of minimally disturbed sites, thus contributing to false conclusions about fish assemblage integrity.

The main concerns are mature fine tailings (MFT) composed of residual hydrocarbons, water, and fine clay. Tailings ponds include toxic contaminants such as heavy metals, and toxic organics including naphthenics. Naphthenic acids and polyaromatic hydrocarbons (PAHs) degrade very slowly and pose a long-term threat to surface and groundwater, as they can be transported in the MFT. Research into improved technologies that would enable densification and settling of the suspended particles is ongoing. In batch tests, BioTiger(TM), a microbial consortium that can metabolize PAHs, demonstrated improved oil sands tailings settling from a Canadian tailings pond. Results also showed, depending on the timing of the measurements, lower suspended solids and turbidity. Elevated total organic carbon was observed in the first 48 hours in the BioTiger(TM)-treated columns and then decreased in overlying water. Oil sands tailings mixed with BioTiger(TM) showed a two-fold reduction in suspended solids within 24 hours as compared to abiotic controls. The tailings treated with BioTiger(TM) increased in microbial densities three orders of magnitude from 8.5 105 CFU/mL to 1.2 108 CFU/mL without any other carbon or energy source added, indicating metabolism of hydrocarbons and other available nutrients. Results demonstrated that bioaugmentation of BioTiger(TM) increased separation of organic carbon from particles in oil sands and enhanced settling with tailings with improved water quality.

Sampling locations were 53-63 km northwest of the FDNPP within a 75-km radius, in close proximity of each other. A ranking of the land uses by their surface soil ( deciduous forest > urban > paddy, and (super 239,240) Pu concentrations ranked as deciduous forest > coniferous forest > paddy > or = urban. Both were quite distinct from that of (super 134) Cs and (super 137) Cs: urban > coniferous forest > deciduous forest > paddy, indicating differences in their sources, deposition phases, and biogeochemical behavior in these soil systems. Although stable (super 127) I might not have fully equilibrated with Fukushima-derived (super 129) I, it likely still works as a proxy for the long-term fate of (super 129) I. Surficial soil (super 127) I content was well correlated to soil organic matter (SOM) content, regardless of land use type, suggesting that SOM might be an important factor affecting iodine biogeochemistry. Other soil chemical properties, such as Eh and pH, had strong correlations to soil (super 127) I content, but only within a given land use (e.g., within urban soils). Organic carbon (OC) concentrations and Eh were positively, and pH was negatively correlated to (super 127) I concentrations in surface water and rain samples. It is also noticeable that (super 127) I in the wet deposition was concentrated in both the deciduous and coniferous forest throughfall and stemfall water, respectively, comparing to the bulk rainwater. Further, both forest throughfall and stemflow water consisted exclusively of organo-iodine, suggesting all inorganic iodine in the original bulk deposition ( approximately 28.6% of total iodine) have been completely converted to organo-iodine. Fukushima-derived (super 239,240) Pu was detectable at a distance approximately 61 km away, NW of FDNPP. However, it is confined to the litter layer, even three years after the FDNPP accident-derived emissions. Plutonium-239,240 activities were significantly correlated with soil OC and nitrogen contents, indicating Pu may be associated with nitrogen-containing SOM, similar to what has been observed at other locations in the United States.

Inland, the southeastern Atlantic Coastal Plain physiographic province extends from the fall line to the shoreline and is underlain by mostly unconsolidated sediments deposited along a passive emergent margin during the Mesozoic and Cenozoic eras. The sediments of the southeastern Atlantic Coastal Plain in South Carolina are stratified quartz sand, clay, calcareous sediment, and conglomerates that dip gently seaward and range from late Cretaceous to Holocene. At the United States Department of Energy Savannah River Site (SRS), the site geologic data archive includes more than 12,000 borings, wells and cone penetrometer soundings, more than 300 km (200 mi) of seismic reflection data, many kilometers of seismic refraction data, and regional soil gas chemical surveys. Many of the borings were cored and more than 80 km (50 mi) of core are archived in the Savannah River National Laboratory (SRNL) core repository. The repository provides a unique opportunity to observe fluvial, deltaic, and shallow marine sand, mud and calcareous sediments of the upper Atlantic Coastal Plain along with the underlying Paleozoic bedrock and Triassic Dunbarton Basin sequences. At the SRS, primary uses of the core are to understand sediment heterogeneity and resulting effect on contaminant migration, groundwater availability, and other environmental applications as well as geotechnical facility siting and foundation design. Physical properties (grain size, porosity, permeability, Kd, etc.) are incorporated into radiological performance assessments and groundwater fate and transport models. Displayed cores will include crystalline basement and rocks of the Triassic Dunbarton Basin as well as fluvial, deltaic, and shallow marine sequences. Detailed characterizations will be featured that illustrate how SRS uses core and subsurface data in real world geotechnical and environmental applications.

A ranking of the land uses by their stable (super 127) I and by their (super 239,240) Pu concentrations were quite distinct from that of (super 134,137) Cs, indicating (super 137) Cs might not be a good geochemical proxy for radioactive (super 129) I or Pu in the long-term, post-FDNPP accident. Being a proxy for the long-term fate of (super 129) I, soil (super 127) I content was well correlated to soil organic matter (SOM) content, regardless of land use type, suggesting that SOM might be an important factor controlling iodine biogeochemistry. Other soil chemical properties, such as Eh and pH, had strong correlations to soil (super 127) I content, but only within a given land use (e.g., within urban soils). Organic carbon (OC) and Eh were positively, and pH was negatively correlated to (super 127) I concentrations in surface water and rain samples. It is also noticeable that (super 127) I in the bulk deposition was concentrated along the rainwater passage likely due to plant evapotranspiration activity, with all inorganic iodine being completely converted to organo-iodine by plant organic matter. (super 239,240) Pu activities of all soil samples were well within the global fallout range, but the Fukushima-derived (super 239,240) Pu was detectable at a distance nearly equal 61 km away, NW of FDNPP. However, it is confined to the litter layer, even three years after the FDNPP accident-derived emissions. (super 239,240) Pu activities were significantly correlated with soil OC and nitrogen contents, indicating Pu may be associated with nitrogen-containing SOM, similar to what has been observed at other locations in the United States, e.g., Savannah River Site (SRS) and Rocky Flats Environmental Technology Site (RFETS). Together, these finding suggest that NOM plays an key role in controlling the fate and transport of I and Pu and may warrant greater consideration for predicting long-term stewardship of contaminated areas and evaluating various remediation options in Japan.

A series of electrochemical measurements of morphologically altered samples, via mechanical milling, was conducted. The measurements indicated that mechanical alternations of the Li2B12H12 morphology makes it an excellent lithium ion conductor in the solid state with exceptional ionic conductivity at room temperature (0.31 mS cm-1) and is compatible with a metallic lithium electrode up to 6.0 V. In addition, all solid state half and full electrochemical cells were assembled and successfully cycled using Li2B12H12 as a solid state electrolyte at temperatures as low as 30 degree C with good capacity retention. The photophysical properties of Li2B12H12 were also investigated. Li2B12H12 has an emission maximum of similar to 460 nm in a variety of solvents with Stokes' shifts up to 175 nm observed.

The low temperature metal hydrides NaAlH sub(4) and Na sub(3)AlH sub(6) were cycled to determine stability of hydrogen capacity over extended cycling. Addition of aluminum and expanded natural graphite were found to enhance the cycling stability of NaAlH sub(4). Potential high temperature metal hydrides were investigated based on NaMg materials. A techno-economic analysis was performed to evaluate the performance a thermal energy storage system based on two metal hydride pairs: NaMgH sub(3):NaAlH sub(4) and NaMgH sub(2)F:Na sub(3)AlH sub(6). The resulting analysis suggests that the two systems have the potential to reach low cost and high efficiency performance targets.

The fuel cycle is necessary to supply and recycle tritium at the required throughput rate; additionally, tritium confinement throughout the facility is needed to meet regulatory and environmental release limits. Small fuel cycle development efforts are sometimes rationalized by stating that tritium processing technology has already been developed by nuclear weapons programs and these existing processes only need rescaling or engineering design to meet the needs of fusion fuel cycles. This paper compares and contrasts features of tritium fusion fuel cycles to United States Cold War era defense program tritium systems. It is concluded that further tritium fuel cycle development activities are needed to provide technology development beneficial to both fusion and defense programs tritium systems.

We characterized the spatial and temporal variability in overmarsh circulation at a 2 km (super 2) Georgia, USA, salt marsh using field observations, dye tracer, and numerical simulations. The marsh bathymetry was created with a high-precision Global Positioning System survey that details the geomorphic structure of intertidal creeks and salt marsh platform features greater than about 1 m in width. We assessed flow path dynamics at four spatial scales ranging from 1 m to 1000 m. Results show the development and decay of simultaneous flow divergence and convergence, concentrated flow and large-scale rotational flow, and strong differences between flood and ebb pathways. This current complexity is set by submergence and emergence of subtle salt marsh platform geomorphic structure, and it highlights the role of topography in system-wide flow processes.

CAP88 is a set of computer programs and data-bases used for estimation of dose and risk from radionuclide emissions to air. At the U.S. Department of Energy's Savannah River Site, CAP88 is used by SRNL for determining compliance with U.S. EPA's National Emission Standards for Hazardous Air Pollutants (40 CFR 61, Subpart H) regulations. Using standardized input parameters, individual runs were conducted for each radionuclide within its corresponding database. Some radioactive decay constants, human usage parameters, and dose coefficients changed between the two versions, directly causing a proportional change in the total effective dose. A detailed summary for select radionuclides of concern at the Savannah River Site ( super(60)Co, super(137)Cs, super(3)H, super(129)I, super(239)Pu, and super(90)Sr) is provided. In general, the total effective doses will decrease for alpha/beta emitters because of reduced inhalation and ingestion rates in V4.0. However, for gamma emitters, such as super(60)Co and super(137)Cs, the total effective doses will increase because of changes U.S. EPA made in the external ground shine calculations.

Modern maps prepared at the national scale (1:7,500,000) show the updip limit of carbonate (outcrop and subsurface) in the Savannah River area extending inland approximately 135 kilometers and describe the possible existence of caves up to 300 meters long and 15 meters high in this region (Davies et al., 1984; Tobin and Weary, 2004). More recently, state and local scale (1:24,000 to 1:1,100,000) maps illustrate more restricted extent of carbonate in the Savannah River area and show isolated occurrences in Aiken County, SC, and Richmond and Burke Counties, GA (Weary, 2008). These maps are excellent tools for defining broad areas that may be susceptible to development of karst, but they are not suitable for site-specific characterization or for defining the presence/absence of karst at a particular site. Recent improvements in the availability, resolution, and processing of LiDAR data in the Central Savannah River Area may help improve the identification of karst on a reconnaissance scale, before sending geologists and geomorphologists to the field to look for evidence of sinkholes, caves, and other karst features.

Reliable climate projections are therefore critical to predicting the future water supply for the United States, but the resolution of the global climate models (GCMs) often used for climate forecasting is too coarse to resolve the changes that can affect hydrology, and hence water supply, at regional to local scales. We therefore apply a statistical downscaling technique that involves a correction of the cumulative distribution functions of the GCM-derived temperature and precipitation for the 20th century, and the application of the same correction to 21st century GCM projections. This is done for three meteorological stations located within the Coosa River basin in northern Georgia, and is used with a surface hydrology model to calculate future river flow statistics for the upper Coosa River.

A total of eight Pt-catalyzed molecular sieve samples were prepared using the Pt-deposition and Pt-ion exchange methods and seven were subsequently analyzed to determine the hydrogen isotope exchange efficiency of the materials. Based on the criteria for the evaluation of the molecular sieve materials, the sample that was catalyzed with 2.0% Pt using the ion exchange method had the highest hydrogen isotope exchange efficiency. Additional testing may be necessary using this particular material.

AN - 1634723003; 25464040 AB - During the last few decades, considerable research efforts have been extended to identify more effective remediation treatment technologies to lower the (129)I concentrations to below federal drinking water standards at the Hanford Site (Richland, USA). Few studies have taken iodate into consideration, though recently iodate, instead of iodide, was identified as the major species in the groundwater of 200-West Area within the Hanford Site. The objective of this study was thus to quantify and understand aqueous radioiodine species transformations and uptake by three sediments collected from the semi-arid, carbonate-rich environment of the Hanford subsurface. All three sediments reduced iodate (IO3(-)) to iodide (I(-)), but the loamy-sand sediment reduced more IO3(-) (100% reduced within 7 days) than the two sand-textured sediments (∼20% reduced after 28 days). No dissolved organo-iodine species were observed in any of these studies. Iodate uptake Kd values ([Isolid]/[Iaq]; 0.8-7.6 L/kg) were consistently and appreciably greater than iodide Kd values (0-5.6 L/kg). Furthermore, desorption Kd values (11.9-29.8 L/kg) for both iodate and iodide were consistently and appreciably greater than uptake Kd values (0-7.6 L/kg). Major fractions of iodine associated with the sediments were unexpectedly strongly bound, such that only 0.4-6.6 % of the total sedimentary iodine could be exchanged from the surface with KCl solution, and 0-1.2% was associated with Fe or Mn oxides (weak NH2HCl/HNO3 extractable fraction). Iodine incorporated into calcite accounted for 2.9-39.4% of the total sedimentary iodine, whereas organic carbon (OC) is likely responsible for the residual iodine (57.1-90.6%) in sediments. The OC, even at low concentrations, appeared to be controlling iodine binding to the sediments, as it was found that the greater the OC concentrations in the sediments, the greater the values of uptake Kd, desorption Kd, and the greater residual iodine concentrations (non-exchangeable, non-calcite-incorporated and non-Mn, Fe-oxide associated). This finding is of particular interest because it suggests that even very low OC concentrations, <0.2%, may have an impact on iodine geochemistry. The findings that these sediments can readily reduce IO3(-), and that IO3(-) sorbs to a greater extent than I(-), sheds light into earlier unexplained Hanford field data that demonstrated increases in groundwater (127)I(-)/(127)IO3(-) ratios and a decrease groundwater (129)IO3(-) concentrations along a transect away from the point sources, where iodine was primarily introduced as IO3(-). While a majority of the radioiodine does not bind to these alkaline sediments, there is likely a second smaller iodine fraction in the Hanford subsurface that is strongly bound, presumably to the sediment OC (and carbonate) phases. This second fraction may have an impact on establishing remediation goals and performance assessment calculations.

Wetlands often link ground and surface-waters, making them strategic systems for potentially limiting migration of uranium contamination. Little is known about how drought periods that result in the drying of wetland soils, and consequent redox changes, affect uranium fate and transport in wetlands. In order to better understand the fate and stability of immobilized uranium in wetland soils, and how dry periods affect the uranium stability, we dosed saturated wetland mesocosms planted with Scirpus acutus with low levels of uranyl-acetate for 5 months before imposing a 9-day drying period followed by a 13-day rewetting period. Concentrations of uranium in mesocosm effluent increased after rewetting, but the cumulative amount of uranium released in the 13 days following the drying constituted less than 1% of the uranium immobilized in the soil during the 5 months prior to the drought. This low level of remobilization suggests that the uranium immobilized in these soils was not primarily bioreduced U(IV), which could have been oxidized to soluble U(VI) during the drought and released in the effluent during the subsequent flood. XANES analyses confirm that most of the uranium immobilized in the mesocosms was U(VI) sorbed to iron oxides. Compared to mesocosms that did not experience drying or rewetting, mesocosms that were sacrificed immediately after drying and after 13 days of rewetting had less uranium in soil near roots and more uranium on root surfaces. Metal-reducing bacteria only dominated the bacterial community after 13 days of rewetting and not immediately after drying, indicating that these bacteria are not responsible for this redistribution of uranium after the drying and rewetting. Results show that short periods of drought conditions in a wetland may impact uranium distribution, but these conditions may not cause large losses of immobilized uranium from the wetland.

21198768 AB - Ceramic waste forms are promising hosts for nuclear waste immobilization as they have the potential for increased durability and waste loading compared with conventional borosilicate glass waste forms. Ceramics are generally processed using hot pressing, spark plasma sintering, and conventional solid-state reaction, however such methods can be prohibitively expensive or impractical at production scales. Recently, melt processing has been investigated as an alternative to solid-state sintering methods. Given that melter technology is currently in use for High Level Waste (HLW) vitrification in several countries, the technology readiness of melt processing appears to be advantageous over sintering methods. This work reports the development of candidate multi-phase ceramic compositions processed from a melt. Cr additions, developed to promote the formation and stability of a Cs containing hollandite phase were successfully incorporated into melt processed multi-phase ceramics. Control of the reduction-oxidation (Redox) conditions suppressed undesirable Cs-Mo containing phases, and additions of Al and Fe reduced the melting temperature.

AN - 1566408941; 25173764 AB - A primary obstacle in understanding the fate and transport of the toxic radionuclide (129)I (a thyroid seeker) is an accurate method to distinguish it from the stable isotope, (127)I, and to quantify the various species at environmentally relevant concentrations (~10(-8) M). A pH-dependent solvent extraction and combustion method was paired with accelerator mass spectrometry (AMS) to measure ambient levels of (129)I/(127)I isotope ratios and iodine speciation (iodide (I(-)), iodate (IO3(-)), and organo-I (OI)) in aquatic systems. The method exhibited an overall uncertainty of 10% or less for I(-) and IO3(-), and less than 30% for OI species concentrations and enabled (129)I measurements as low as 0.001 Bq/L (1 Bq/L=10(-13) M). The method was used to analyze groundwater from the Savannah River Site (SRS), South Carolina, USA, along a pH, redox potential (Eh), and organic carbon gradient (8-60 μM DOC). The data confirmed that the (129)I/(127)I ratios and species distribution were strongly pH dependent and varied in a systematic manner from the strongly acidic source. While (129)I speciation in plume samples containing total I concentrations >1.7 Bq/L was similar whether measured by AMS or GC-MS ([I(-)]≫[IO3(-)]=[OI]), AMS enabled (129)I speciation measurements at much lower concentrations than what was possible with GC-MS. AMS analyses demonstrated that groundwater samples minimally impacted by the plume were still orders of magnitude higher than ambient (129)I concentrations typically found elsewhere in the USA groundwaters and rivers. This is likely due to past atmospheric releases of volatile (129)I species by SRS nuclear reprocessing facilities near the study site. Furthermore, the results confirmed the existence of (129)I not only as I(-), but also as OI and IO3(-) species.

AN - 1826605550; 25264421 AB - 129I is commonly either the top or among the top risk drivers, along with 99Tc, at radiological waste disposal sites and contaminated groundwater sites where nuclear material fabrication or reprocessing has occurred. The risk stems largely from 129I having a high toxicity, a high bioaccumulation factor (90% of all the body's iodine concentrates in the thyroid), a high inventory at source terms (due to its high fission yield), an extremely long half-life (16M years), and rapid mobility in the subsurface environment. Another important reason that 129I is a key risk driver is that there is uncertainty regarding its biogeochemical fate and transport in the environment. We typically can define 129I mass balance and flux at sites, but cannot predict accurately its response to changes in the environment. As a consequence of some of these characteristics, 129I has a very low drinking water standard, which is set at 1 pCi/L, the lowest of all radionuclides in the Federal Register. Recently, significant advancements have been made in detecting iodine species at ambient groundwater concentrations, defining the nature of the organic matter and iodine bond, and quantifying the role of naturally occurring sediment microbes to promote iodine oxidation and reduction. These recent studies have led to a more mechanistic understanding of radioiodine biogeochemistry. The objective of this review is to describe these advances and to provide a state of the science of radioiodine biogeochemistry relevant to its fate and transport in the terrestrial environment and provide information useful for making decisions regarding the stewardship and remediation of 129I contaminated sites. As part of this review, knowledge gaps were identified that would significantly advance the goals of basic and applied research programs for accelerating 129I environmental remediation and reducing uncertainty associated with disposal of 129I waste. Together the information gained from addressing these knowledge gaps will not alter the observation that 129I is primarily mobile, but it will likely permit demonstration that the entire 129I pool in the source term is not moving at the same rate and some may be tightly bound to the sediment, thereby smearing the modeled 129I peak and reducing maximum calculated risk.

Immobilizing these radionuclides, especially TcO (sub 4) (super -) and I (super -) , has been challenging. TcO (sub 4) (super -) and I (super -) bind very weakly to most sediments, such that distribution coefficients (K (sub d) values; radionuclide concentration ratio of solids to liquids) are typically 1 X 10 (super 5) mL/g), I (super -) (K (sub d) > or = 1 X 10 (super 4) mL/g), and Cs (super +) (K (sub d) > 1 X 10 (super 3) mL/g) and also demonstrated a largely irreversible binding of the radionuclides. Activated carbon GAC 830 was effective at sorbing TcO (sub 4) (super -) (K (sub d) > 1 X 10 (super 5) mL/g) and I (super -) (K (sub d) = 6.9 X 10 (super 3) mL/g), while a surfactant modified chabazite was effective at sorbing TcO (sub 4) (super -) (K (sub d) > 2.5 X 10 (super 4) mL/g) and Cs (super +) (K (sub d) > 6.5 X 10 (super 3) mL/g). Several sorbents were effective for only one radionuclide, e.g., modified zeolite Y had TcO (sub 4) (super -) K (sub d) > 2.3 X 10 (super 5) mL/g, AgS had I (super -) K (sub d) = 2.5 X 10 (super 4) mL/g, and illite, chabazite, surfactant modified clinoptilolite, and thiol-SAMMS had Cs (super +) K (sub d) > 10 (super 3) mL/g.

In natural waters, the importance of physical associations and biochemical interactions between microalgae and bacteria is generally well appreciated, but the significance of these interactions to algal biofuels production have not been investigated. Here, we provide a preliminary report on the frequency of co-occurrence between indole-3-acetic acid (IAA)-producing bacteria and green algae in natural and engineered ecosystems. Growth experiments with unicellular algae, Chlorella and Scenedesmus, revealed IAA concentration-dependent responses in chlorophyll content and dry weight. Importantly, discrete concentrations of IAA resulted in cell culture synchronization, suggesting that biochemical priming of cellular metabolism could vastly improve the reliability of high density cultivation. Bacterial interactions may have an important influence on algal growth and development; thus, the preservation or engineered construction of the algal-bacterial assembly could serve as a control point for achieving low input, reliable production of algal biofuels.

Lithium bis(trifluoromethylsulfonyl)imide (LiTF sub(2)N) in tetraethylene glycol dimethyl ether (TEGDME) was used as the electrolyte during testing. The effect of manganese/manganese oxide addition on the performance of the carbons was compared to that of the bare carbons in a cycling study. From CV results, it was found that single walled carbon nanotubes (SWCNT) had the highest peak current density per gram for ORR and OER than the other types of carbon studied. The SWCNT ORR peak decreased 49% after 100 cycles and only 36% when manganese/manganese oxide was added. The high activity of SWCNT with manganese/manganese oxide spheres make it a desirable material to use as the cathode for Li-air batteries.

Results of experiments to characterize SRS soil samples, to examine aspects of their radiocesium sorption, and to determine how much of their natural Cs is accessible for chemical extraction and isotope dilution are presented in support of mechanistic hypotheses to explain Cs sorption and fixation in HIV grains. The HIV is responsible for most of the soil cation exchange capacity, and concentrations of naturally occurring Cs, Rb, and K in soil samples are closely related to the concentration of HIV. Experiments with (super 137) Cs to examine (1) sorption kinetics, (2) blocking of exchange sites with silver thiourea, and (3) susceptibility of sorbed (super 137) Cs to chemical extraction, support the idea that added Cs is sorbed at different kinds of cation exchange sites in HIV grains. Sites highly selective for Cs but relatively few in number are inferred to exist in interlayer wedge zones within such grains. Little of the naturally occurring Cs in the soil samples was extractable by chemical agents that would remove Cs from ordinary cation-exchange sites and from within non-silicate soil components. Furthermore, most of the natural Cs was inaccessible for isotope dilution under slightly acidic conditions approximating the natural soil environment. These observations support the idea that most of the Cs in these soils has become effectively fixed in the narrower parts of interlayer wedge zones. Control of Cs uptake and fixation by highly Cs-selective interlayer wedge sites would account for the large distribution coefficients found for (super 137) Cs at the low aqueous Cs concentrations typical of environmental systems and also for the relatively large concentrations of stable Cs in the SRS soils.

Previous work estimating the iodine sorption has not allowed for samples to reach full equilibrium and field studies have reported significant fractions of up to three major species of iodine; therefore, further research into the kinetics of iodine sorption to sediments is warranted. The objective of this study is to investigate the kinetics of iodine sorption in the presence of subsurface upland sediments and wetland sediments from an area within an (super 129) I plume at the Savannah River Site in Aiken, SC. Batch sorption studies for these systems took longer than 8 weeks to reach equilibrium, which is significant as previous studies did not reach such timescales. In addition, experiments were conducted under oxic and anoxic conditions. Results confirm that there are three species present in these systems (iodide, iodate, and organo-iodine) with a majority as organo-iodine species at equilibrium for systems with high organic matter content. It is notable that the anoxic conditions exhibited reduced sorption for the iodate species to wetland sediment with high organic matter. Abstract Copyright (2014) Elsevier, B.V.

There are a number of extremely sharp biogeochemical interfaces in wetlands that could alter radionuclide speciation and promote accumulation. The objective of this study was to determine if a wetland concentrated (super 129) I emanating from a former waste disposal basin located on the Savannah River Site (SRS) in South Carolina, USA. Additionally, studies were conducted to evaluate the role of sediment organic matter in immobilizing the radioiodine. Groundwater samples were collected along a 0.7-km transect away from the seepage basin and in the downstream wetlands. The samples were analyzed for (super 129) I speciation (iodide (I (super -) ), iodate (IO (sub 3) (super -) ), and organo-I). Groundwater (super 129) I concentrations in many locations in the wetlands (as high as 59.9 Bq L (super -1129) I) were greatly elevated with respect to the source term (5.9 Bq L (super -1129) I). (super 129) I concentration profiles in sediment cores were closely correlated to organic matter concentrations (r (super 2) = 0.992; n = 5). While the sediment organic matter promoted the uptake of (super 129) I to the wetland sediment, it also promoted the formation of a soluble organic fraction: 74% of the wetland groundwater (super 129) I could pass through a 1 kDa (<1 nm) membrane and only 26% of the (super 129) I was colloidal. Of that fraction that could pass through a 1 kDa membrane, 39% of the (super 129) I was organo-I. Therefore, while wetlands may be highly effective at immobilizing aqueous (super 129) I, they may also promote the formation of a low-molecular-weight organic species that does not partition to sediments. This study provides a rare example of radioactivity concentrations increasing rather than decreasing as it migrates from a point source and brings into question assumptions in risk models regarding continuous dilution of released contaminants.

However, only a relatively small number of pathways, most importantly (super 137) Cs in fish and deer, have contributed significantly to doses and risks to the public. The "effective" half-lives (T (sub e) ) of (super 137) Cs (which include both physical decay and environmental dispersion) in Savannah River floodplain soil and vegetation and in fish and white-tailed deer from the SRS were estimated using long-term monitoring data. For 1974-2011, the T (sub e) s of (super 137) Cs in Savannah River floodplain soil and vegetation were 17.0 years (95% CI = 14.2-19.9) and 13.4 years (95% CI = 10.8-16.0), respectively. These T (sub e) s were greater than in a previous study that used data collected only through 2005 as a likely result of changes in the flood regime of the Savannah River. Field analyses of (super 137) Cs concentrations in deer collected during yearly controlled hunts at the SRS indicated an overall T (sub e) of 15.9 years (95% CI = 12.3-19.6) for 1965-2011; however, the T (sub e) for 1990-2011 was significantly shorter (11.8 years, 95% CI = 4.8-18.8) due to an increase in the rate of (super 137) Cs removal. The shortest T (sub e) s were for fish in SRS streams and the Savannah River (3.5-9.0 years), where dilution and dispersal resulted in rapid (super 137) Cs removal. Long-term data show that T (sub e) s are significantly shorter than the physical half-life of (super 137) Cs in the SRS environment but that they can change over time. Therefore, it is desirable have a long period of record for calculating T (sub e) s and risky to extrapolate T (sub e) s beyond this period unless the processes governing (super 137) Cs removal are clearly understood.

In order to assess the potential human and environmental risk associated with these recent initiatives, improved understanding of the fate and transport of Pu in the SRS subsurface environment is necessary. The hypothesis of this study was that the more mobile forms of Pu, Pu(V) and Pu(VI), would be reduced to the less mobile Pu(III/IV) oxidation states under ambient SRS subsurface conditions. Laboratory-scale dynamic flow experiments (i.e., column studies) indicated that Pu(V) was very mobile in SRS sediments. At higher pH values the mobility of Pu decreased and the fraction of Pu that became irreversibly sorbed to the sediment increased, albeit, only slightly. Conversely, these column experiments showed that Pu(IV) was essentially immobile and was largely irreversibly sorbed to the sediment. More than 100 batch sorption experiments were also conducted with four end-member sediments, i.e., sediments that include the chemical, textural, and mineralogical properties likely to exist in the SRS. These tests were conducted as a function of initial Pu oxidation state, pH, and contact time and consistently demonstrated that although Pu(V) sorbed initially quite weakly to sediments, it slowly, over the course of <33 days, sorbed very strongly to sediments, to approximately the same degree as Pu(IV). This is consistent with our hypothesis that Pu(V) is reduced to the more strongly sorbing form of Pu, Pu(IV). These studies provide important experimental support for a conceptual geochemical model for dissolved Pu in a highly weathered subsurface environment. That is that, irrespective of the initial oxidation state of the dissolved Pu introduced into a SRS sediment system, Pu(IV) controls the environmental transport within a couple weeks and Pu strongly binds to the sediment, limiting its mobility.

Under oxidized conditions, U was highly retained by the SRS wetland sediments. In contrast to other similar but much lower natural organic matter (NOM) sediments, significant sorption of U onto the SRS sediments was observed at pH 8. Sequential extraction indicated that the U species were primarily associated with the acid soluble fraction (weak acetic acid extractable) and organic fraction (Na-pyrophosphate extractable). Uranium L (sub 3) -edge XANES spectra of the U-bound sediments were nearly identical to that of uranyl acetate. Based on fluorescence mapping, U and Fe distributions in the sediment were poorly correlated, U was distributed throughout the sample and did not appear as isolated U mineral phases. The primary oxidation state of U in these oxidized sediments was U(VI), and there was little evidence that the high sorptive capacity of the sediments could be ascribed to abiotic or biotic reduction to the less soluble U(IV) species or to secondary mineral formation. Collectively, this study suggests that U may be strongly bound to wetland sediments, not only under reducing conditions by reductive precipitation, but also under oxidizing conditions through NOM-uranium bonding.

Multiphase ceramic waste forms have been studied extensively as a potential host matrix for nuclear waste. Understanding the speciation, partitioning, and release behavior of radionuclides immobilized in multiphase ceramic waste forms is a critical aspect of developing the scientific and technical basis for nuclear waste management. In this study, we evaluated a sodalite-bearing multiphase ceramic waste form (i.e., fluidized-bed steam reform sodium aluminosilicate [FBSR NAS] product) as a potential host matrix for long-lived radionuclides, such as technetium ( (super 99) Tc). The FBSR NAS material consists primarily of nepheline (ideally NaAlSiO (sub 4) ), anion-bearing sodalites (ideally M (sub 8) [Al (sub 6) Si (sub 6) O (sub 24) ]X (sub 2) , where M refers to alkali and alkaline earth cations and X refers to monovalent anions), and nosean (ideally Na (sub 8) [AlSiO (sub 4) ] (sub 6) SO (sub 4) ). Bulk X-ray absorption fine structure analysis of the multiphase ceramic waste form, suggest rhenium (Re) is in the Re(VII) oxidation state and has partitioned to a Re-bearing sodalite phase (most likely a perrhenate sodalite Na (sub 8) [Al (sub 6) Si (sub 6) O (sub 24) ](ReO (sub 4) ) (sub 2) ). Rhenium was added as a chemical surrogate for (super 99) Tc during the FBSR NAS synthesis process. The weathering behavior of the FBSR NAS material was evaluated under hydraulically unsaturated conditions with deionized water at 90 degrees C. The steady-state Al, Na, and Si concentrations suggests the weathering mechanisms are consistent with what has been observed for other aluminosilicate minerals and include a combination of ion exchange, network hydrolysis, and the formation of an enriched-silica surface layer or phase. The steady-state S and Re concentrations are within an order of magnitude of the nosean and perrhenate sodalite solubility, respectively. The order of magnitude difference between the observed and predicted concentration for Re and S may be associated with the fact that the anion-bearing sodalites contained in the multiphase ceramic matrix are present as mixed-anion sodalite phases. These results suggest the multiphase FBSR NAS material may be a viable host matrix for long-lived, highly mobilie radionuclides which is a critical aspect in the management of nuclear waste.

Fish and macroinvertebrates responded differently to anthropogenic disturbance: macroinvertebrates were affected most strongly by in-stream habitat quality and fish by the presence of a reservoir in the catchment. Neither taxonomic group were significantly affected by the catchment scale disturbance, probably because the proportions of disturbed land in the study areas were low. Fish may be particularly sensitive to the presence of reservoirs because of their need to cover relatively large distances to complete life cycles and maintain viable populations and because of their sensitivity to the effects of invasive reservoir species, particularly predator fishes. Although not an important predictor in itself, disturbance at the watershed scale was significantly and positively related to in-stream habitat quality, indicating that watershed disturbance had an important indirect effect on aquatic organisms. Direct and indirect ordination showed that the metric data were more strongly related to the disturbance variables than the taxonomic data from which the metrics were derived, possibly because the metrics were less sensitive than the taxon-specific abundances to nondisturbance-related factors. Other factors that may have contributed to this result include greater statistical tractability of the metric data and the relatively high sensitivity of the collective properties represented by the metrics to disturbance-related environmental changes.

Three experiments assessed the effects of apatite, organoclay, zeolite, and biopolymers (chitosan and xanthan) on metal mobility, retention, and speciation. The first showed that the amendments individually and in mixtures (2 percent dry weight) reduced the concentrations of Cr, Co, Ni, and Pb in water extracts from reduced sediment. The second experiment, which used sequential extraction procedures to evaluate the effects of the amendments on metal speciation, showed that the amendments reduced the potentially mobile fractions of Pb, Zn, Ni, Cr, and Cd that are likely to be bioavailable. Last, column studies showed that active caps composed of the amendments prevented the diffusive transport of metals from contaminated sediment over six months. In addition, there was a "zone of influence" beneath the caps in which water extractable concentrations of metals declined substantially compared with untreated sediment.

In this class of materials the actinides present particular challenges, such as the recovery of actinides and fission products found in irradiated nuclear fuels. Important parameters that one can tune for successful ion-exchange separations include the chemical and physical properties of the ion exchanger, the chemical composition of feed and eluting solutions, oxidation state, temperature, and pressure. A key metric in ion-exchange separations is the inherent selectivity of an ion-exchanger for a particular sorbate. This is particularly true when the feed solution is comprised of multiple chemically similar ions. We propose a systematic study of the titanium-based exchangers, such as sodium titanates, which are known to selectively separate strontium actinide ions from high ionic-strength solutions, in order to determine the mechanism of selectivity. Because these are nano-crystalline materials we employed high energy x-ray scattering and the Pair Distribution Function to gain insight into the structures of these materials in their native and ion-exchanged forms.

In arid settings, typical for milling sites, shallow groundwater is transferred into the vadose zone and atmosphere via evaporation, transpiration and diffuse surface seepage. During these transfers, dissolved constituents precipitate as evaporite minerals (e.g., blodite, thenardite, and halite) along with accessory minerals (e.g., carnotite) containing trace elements such as uranium. In locations where the water table is relatively deep (>2 m), these precipitates will accumulate as nonpedogenic intervals in the deep vadose zone near the capillary fringe, around the roots of phreatophyte plants, and near surface seeps. In areas where the water table is shallow, precipitates will also accumulate at the soil surface as a result of capillarity and evaporation. The accumulation and distribution of constituents associated with milling/extraction impacted groundwater is analogous to natural evaporite ore deposits in North America, Australia, Europe and Africa. The sites in Tuba City Arizona and Riverton Wyoming are archetype mill sites in arid settings, representing deep and shallow water table cases, respectively. Available hydrological, geochemical and radiological (aerial gamma) data from these sites provide key insights related to contaminant fate and transport. At Tuba City, hydrological and geochemical processes limit the size of the groundwater plume and reduce the potential for contaminated groundwater to crop out at Moenkopi Wash, while eolian processes have resulted in limited surficial dispersal of milling related constituents along the primary wind vectors. At both sites, milling-related evaporite minerals that have formed in the near-field and mid plume area will sustain elevated groundwater concentrations of anthropogenic constituents such as sulfate and uranium for an extended timeframe.

KCl-MgCl sub(2):68-32 mol% and LiF-NaF-KF: 46.5-11.5-42 mol % (commonly referred to as FLiNaK) are two promising salts from heat transfer and economic perspectives [2]. Under certain conditions, these halide salts can be corrosive to alloys. Understanding these conditions and controlling the salt chemistry can potentially allow for application of molten salts for heat transfer. This summary describes the effectiveness of Mg and Zr as redox agents to hold the redox potential of the salt at a point where Cr dissolution from Hayes-230 into both KCl-MgCl sub(2) and FLiNaK, and transport of Cr from the Haynes-230 to the Ni crucibles is suppressed. The effectiveness of redox control to effectively stop Cr transport is promising for schemes that propose to use welded Ni plating on high temperature alloys for corrosion protection, and high Cr high temperature alloys.

Cladding oxidation also causes mechanical breakdown[1] and can leave the nuclear fuel unprotected and lead to fission product release. These effects were seen in the Fukushima nuclear disaster.[2] Improving the oxidation resistance of nuclear fuel cladding could prevent hydrogen generation during a LOCA event and nuclear fuel cladding degradation. One method to improve Zry cladding oxidation resistance is to coat it with a material that has high oxidation resistance at high temperature. The coating also needs good thermal conductivity to maintain adequate heat transfer during normal operation. Ceramic materials often are resistant to oxidation at high temperatures but possess low thermal conductivity. Metals have good thermal conductivity but low oxidation resistance at accident temperatures approaching 1200[degrees]C. MAX phase materials [3] are novel ternary carbides that conduct heat similar to metals with oxidation resistance similar to ceramics. This work extends previous research investigating MAX phase materials for nuclear applications [4] and describes the development and optimization of MAX phase coatings to create an accident tolerant fuel cladding that is fully compatible with the present fuel design for the light water reactor fleet.

New innovative measurement and sensor technology need to be in place for verification of SNM material in process, rapid analysis of small samples, and verification of possible diversion methods. Because proliferation concerns and materials control and accountability (MC&A) purpose verification of SNM material in aqueous processed its needed, for example during spent fuel (SF) reprocessing. Isotope dilution mass spectroscopy (IDMS) is the most reliable analytical method for the accountability measurements of nuclear materials in spent fuel reprocessing plants. However, such a traditional method involves tedious procedures and requires highly skilled operators to separate analyte from complicated matrices such as waste solutions. It is large in quantity and expensive in sampling. Radiation detection methods for very small volumes (< 10 super(-9)L) are also limited due to several factors including background level, selfshielding and attenuation due to process configuration. This paper aims to present preliminary results and modeling of an opto-fluidic devices coupled with a labon-a-chip for the interrogation of SNM-surrogates in diluted media. This study provides a first step towards the fundamental understanding of the transport and detection of species in a nano-channel array. Another outcome of this study is to evaluate the potential of integration of spectroscopy techniques such as Raman, UV-Vis and photoluminescence, in a nano-channels array system.

Technologies for the diagnosis and prognosis of NPP systems can improve verification of the health of the structure that can eventually reduce the likelihood of inadvertently failure. Recently investigated piezoelectric wafer active sensors (PWAS) open the possibilities to develop and deploy such system. Piezoelectric wafer active sensors are widely used in structural health monitoring (SHM) to determine the presence of cracks, delaminations, disbonds, and corrosion. Durability and survivability of PWAS under environmental exposures has been tested before. However the irradiation effects, pertinent to nuclear facilities for PWAS, have not been studied yet. This paper presents a study on PWAS that exposed to high energy gamma radiation. PWAS were irradiated using a Co-60 gamma source in an irradiator with different exposure times. The dose rate and total absorbed dose were calculated using Monte Carlo simulations (MCNPX). The PWAS material properties, electrical contact change were characterized through a series of tests. The electro-mechanical impedance spectrum (EMIS) of PWAS was measured before and after irradiation. This study not only provides the fundamental understanding of the PWAS irradiation survivability but also tests the potential of PWAS as irradiation sensors for nuclear applications.

Despite many years of active remediation, the groundwater remains acidic and contaminated with significant levels of U(VI) and other radionuclides. Monitored Natural Attenuation (MNA) is a desired closure strategy for the site, based on the premise that regional flow of clean background groundwater will eventually neutralize the groundwater acidity, immobilizing U(VI) through adsorption. An in situ treatment system is currently in place to accelerate this in the downgradient portion of the plume and similar measures could be taken upgradient if necessary. Understanding the long-term pH and U(VI) adsorption behavior at the site is critical to assess feasibility of MNA along with the in-situ remediation treatments. This paper presents a reactive transport (RT) model and uncertainty quantification (UQ) analyses to explore key controls on the U(VI)-plume evolution and long-term mobility at this site. Two-dimensional numerical RT simulations are run including the saturated and unsaturated (vadose) zones, U(VI) and H (super +) adsorption (surface complexation) onto sediments, dissolution and precipitation of Al and Fe minerals, and key hydrodynamic processes are considered. UQ techniques are applied using a new open-source tool that is part of the developing ASCEM reactive transport modeling and analysis framework to: (1) identify the complex physical and geochemical processes that control the U(VI) plume migration in the pH range where the plume is highly mobile, (2) evaluate those physical and geochemical parameters that are most controlling, and (3) predict the future plume evolution constrained by historical, chemical and hydrological data. The RT simulation results show a good agreement with the observed historical pH and concentrations of U(VI), nitrates and Al concentrations at multiple locations. Mineral dissolution and precipitation combined with adsorption reactions on goethite and kaolinite (the main minerals present with quartz) could buffer pH at the site for long periods of time. UQ analysis using the Morris one-at-a-time (OAT) method indicates that the model/parameter is most sensitive to the pH of the waste solution, discharge rates, and the reactive surface area available for adsorption. However, as a key finding, UQ analysis also indicates that this model (and parameters) sensitivity evolves in space and time, and its understanding could be crucial to assess the temporal efficiency of a remediation strategy in contaminated sites. Results also indicate that residual U(VI) and H (super +) adsorbed in the vadose zone, as well as aquifer permeability, could have a significant impact on the acidic plume long-term mobility.

Chitosan is being used in a growing number of biomedical and environmental applications for its intrinsic metal chelating properties. One potential use of chitosan is as a component of active caps. Active capping is a technology employed to sequester metal or organic pollutants in aquatic sediments. In order to be used in this context, chitosan must be modified. Chemically cross-linking chitosan increases its structural integrity, making it more resistant to shearing and biodegradation. Other modifications to the biopolymer may increase its affinity for certain metals. The presenters are investigating how chemical modifications to chitosan may lead to inexpensive, environmentally benign, and widely available derivatives that can be used for remediation of sediments contaminated with radioactive isotopes.

This work was conducted to support the design and operation of a waste treatment process focused on treating dissolved, high-sodium salt waste solutions for the removal of specific radionuclides. Normal operating conditions and accident scenarios (including loss of solution flow, inadvertent drainage, and loss of active cooling) were evaluated for the ion exchange column using bounding conditions to establish the design safety basis. The modeling results demonstrate that the baseline design using one central and four outer cooling tubes provides a highly efficient cooling mechanism for reducing the maximum column temperature. In-tank modeling results revealed that an idealized hemispherical mound shape leads to the highest tank floor temperatures. In contrast, even large volumes of CST distributed in a flat layer with a cylindrical shape do not result in significant floor heating.

Cs-137 is a well-known fission product that has been produced, stored, and handled in this and other US Department of Energy facilities. Documenting the mobility of (super 137) Cs and its sorption by geologic materials is important to predict long-term behavior of (super 137) Cs migrating from contaminated sites such as the SRS. Three uncontaminated (radionuclide free) soil cores were used to study Cs and other alkali metals in the SRS soils. Based on the mineralogy, clay content, and parent material, each core is known to represent a different stage of weathering. For each core, depth profiles of (1) mineral composition, (2) acid-extractable Cs, Rb, K, Sr, and Ba ions, and (3) clay content were collected. These data permit a test of our hypotheses that (1) Cs has been favorably enriched with respect to K in the soils as a result of long-term weathering processes and (2) that this Cs will affect the ability of soils at the SRS to adsorb (super 137) Cs and (3) interlayer wedge zones in highly weathered mica particles, now mostly hydroxy-interlayered vermiculite (HIV), may be responsible for selective uptake of Cs and Rb from soil solution and for their fixation. Rietveld modeling of synchrotron powder X-Ray diffractograms provides a quantitative determination of the clay fraction (< 2um). Acid extractions of ions from soil fine fractions show that the ion concentrations vary sympathetically with depth. The peak in extracted ion concentration in each core peaks not far below the point where the clay content becomes more than 10% of the soil (going downward) and thus seems to be controlled more by clay content than by clay mineralogy. Stable Cs is significantly enriched with respect to K in all three soil cores. During soil formation, K is increasingly removed as weathering progresses, and Cs and Rb are preferentially retained in the soils. The longer a soil has undergone weathering at the SRS, the more enriched it has become in Cs/K (and Rb/K) with respect to the average for upper continental crust. Preliminary molecular modeling results support the hypothesis that Cs is the sterically most favored ion in the interlayer wedge zone of HIV. These preliminary results suggest that Cs can be sorbed effectively at the wedge-apex sites of HIV by electrostatic attraction.

ASCEM is an open source and modular computing framework that incorporates new advances and tools for predicting contaminant fate and transport in natural and engineered systems. ASCEM is designed to integrate modeling tools under one framework. It is designed to facilitate integrated approaches to modeling and site characterization, and provide robust and standardized assessments of performance and risk for EM cleanup and closure activities. It is linked with applied field research sites funded by EM. The ASCEM project has continued development of capabilities, with emphasis on both the Platform and Integrated Toolsets and High-Performance Computing (HPC) multiprocess simulator. The Platform capabilities provide the user interface and tools for end-to-end model development, starting with definition of the conceptual model, management of data for model input, sensitivity analysis, model calibration and uncertainty analysis, and processing of model output, including visualization. The HPC capabilities target increased functionality of process representations, toolsets for interaction with Platform, and verification and model confidence building. In the fall of 2013, ASCEM will publicly release the basic R&D version of the code. The "User Release" will consists of a description of the software capabilities, a downloadable version of the toolsets with accompanying input files, and tutorials based on select test cases. Outreach efforts consisting of direct user interactions will completed along with a series of workshops in 2014. Continued enhancement of the ASCEM family of codes will also occur in 2014. Development efforts will include enhancing geochemistry and reactive transport capabilities for the HPC simulator and adding both risk and decision support to the Platform. This presentation will describe specifics of the release as well as the test cases and initial feedback.

The SRS is the focus of an extensive remediation project by the US Department of Energy; due the production and storage of (super 137) Cs and other radionuclides at this facility. Documenting the mobility of (super 137) Cs and its sorption by geologic materials is important to predict long-term behavior of (super 137) Cs migrating from the SRS and other contaminated sites. Unique depth profiles of (1) mineral composition, (2) soil texture, and (3) acid-extractable alkalis were collected. Mineralogical characterization of the soils suggests that each core represents a different stage of weathering progression. These data enable a test of our hypotheses that (1) Cs has been favorably enriched wrt K in the soils as a result of long-term weathering, (2) this Cs will affect the ability of soils at the SRS to adsorb (super 137) Cs and, (3) interlayer wedge zones in weathered mica particles, now mostly hydroxy-interlayered vermiculite (HIV), may be responsible for selective uptake of Cs and Rb from soil solution and for their fixation. Clay (10% clay. Stable Cs is significantly enriched with respect to K in all three soil cores. K is increasingly removed as weathering progresses, and Cs and Rb are preferentially retained. The Cs/K and Rb/K ratio of acid-leachates are interpreted to show that SRS soils have sorbed and retained Cs and Rb in non-exchangeable sites in clay minerals during pedogenesis. Preliminary molecular modeling results support the hypothesis that Cs is the sterically most favored ion in the interlayer wedge zone of HIV. These preliminary results suggest that Cs can be sorbed effectively at the wedge-apex sites of HIV by electrostatic attraction.

For example, in sediments collected from a region of SRS, close to a wetland and a groundwater plume, (super 239,240) Pu concentrations correlated with organic carbon contents. However, previous studies reported Pu can be transported several kilometers in surface water systems through wind/water interactions. The role of natural organic matter (NOM) in immobilizing or re-mobilizing Pu thus has been demonstrated. It was found that partitioining coefficients (K (sub d) s) of intact humic acids (HAs) were sigificantly higher than those were treated with HF, lowering chelating sites for Pu or hydrophobicity differences between the two types HAs. K (sub d) s of Pu (IV) with HAs were higher at low pH (4.4) than those at high pH (7.1), in contrast to the observation of Pu sorption to most mineral phases, possibly caused by the increased solubility of HA under more alkaline conditions. Though the colloidal fraction of HAs only accounts for a minor fraction of total OC (<5%) at pH 4.4, Pu binding to HAs accounts for 61-83% of the total added Pu, indicating colloidal organic matter as the mobile Pu carrier in the wetland area. Lastly, (super 239,240) Pu concentrations were found to be positively correlated with particulate hydroxamate and nitrogen contents, indicating binding to siderophores.

Azw-3k, through the production of reactive oxygen species AN - 1477832435; 2014-004027 AB - Iodine-129 is one of the most persistent radionuclides released from nuclear reprocessing facilities. With its longevity (half-life: 16 Myr) and biophilic nature (it accumulates in thyroid glands), iodine-129 is a potential human health threat. Thus, it is important to understand the behaviour of iodine in the natural environments. Roseobacter spp. are widely-distributed and comprise up to 15 approximately 20% of bacterial community in coastal/marine environments, and at least one member of this genus, Roseobacter sp. Azw-3k, facilitates extracellular Mn oxidation by releasing superoxide anions (O (sub 2) (super -) ). We hypothesized that Roseobacter. sp. Azw-3k could mediate iodide oxidation through the production of extracellular superoxide anions and/or biogenic Mn(IV) oxides. Without Mn(II), Azw-3k cultures transformed approximately 90% of provided iodide (10 mM) into organo-iodine and iodate within 6 days, whereas in the presence of Mn(II), iodide oxidation only occurred after an initial period of Mn(IV) formation ( approximately 12 days). Heat-killed cells did not transform iodide. O (sub 2) (super -) production rates peaked at day 3, corresponding to early stationary phase of the cultures and the peak of iodide oxidation, and ceased after day 15. The results suggest that biogeneic O (sub 2) (super -) , but not biogenic Mn oxides, were involved in the iodide oxidation process. However, iodide oxidation also occurred in the presence of the O (sub 2) (super -) scavengers, Cu (super 2+) and superoxide dismutase. Results suggest that Azw-3k-mediated iodide oxidation could be facilitated by two reactive oxygen species, O (sub 2) (super -) and its hydrolysis product, H (sub 2) O (sub 2) .

This kind of technology is beneficial when decommissioning and decontamination of nuclear faculties occur. The key components of the RadBall registered technology include a tungsten outer shell that houses a radiosensitive PRESAGE registered polymer. The 1.0-cm-thick tungsten shell has a number of holes that allow photons to reach the polymer, thus generating radiation tracks that are analyzed to characterize the radiation sources within the contaminated area being considered. Facilities being mapped frequently have to be shut down to minimize radiation exposures to workers; therefore, reducing the mapping or characterization time is significant The objective of this study was to reduce the RadBall registered deployment time by increasing the radiosensitivity of the PRESAGE registered formulation. The new formulation is four times more radiosensitive than the original formulation. Consequently, RadBall registered deployment times can be reduced fourfold, which is a considerable improvement.

Comprehensive modeling of the transport and fate of this release was performed including the characterization of the initial three-phased chlorine release, a detailed determination of the local atmospheric conditions acting to generate, disperse, and deplete the chlorine vapor cloud, the establishment of physical exchange mechanisms between the airborne vapor and local surface waters, and local aquatic dilution and mixing.Previous studies of large chlorine releases have concluded that depletion of the resulting vapor cloud through physical and chemical reactions with sunlight, atmospheric constituents, and local surfaces can significantly reduce the areal extent over which the vapor poses a toxicological hazard. For Graniteville, modeling results were the most consistent with available data on human health effects, animal and fish mortality, and vegetation damage when an effective deposition velocity in the lower end of a range of values commonly cited in other studies (1 cm s-1) was applied. This relatively small deposition is attributed to a lack of sunlight, a limited uptake in vegetation due to rapid stomatal damage, and the limited presence of nearby man-made structures. Explicit simulations of chlorine deposition into adjacent surface waters were based on a modified Henry's Law approach and resulted in the transfer of an estimated 21 kg of chlorine into these waters.

AN - 1221133625; 23141377 AB - Pu, U, Np, Am and Tc are among the major risk drivers at nuclear waste management facilities throughout the world. Furthermore, uranium mining and milling operations have generated an enormous legacy of radioactively contaminated soils and groundwater. The sorption process of radionulcides onto ubiquitous Fe (hydr)oxides (FHOs; hematite, magnetite, goethite and ferrihydrite) is one of the most vital geochemical processes controlling the transport and fate of radionuclides and nuclear wastes in the subsurface zones. Meanwhile, understanding molecular-level chemical speciation of radionuclides onto FHOs is crucial to model their behavior in subsurface environments, and to develop new technologies for nuclear waste treatment and long-term remediation strategies for contaminated soils and groundwater. This review article aims (1) to provide risk or performance assessment modelers with macroscopic distribution coefficient (K(d)) data of Pu, U, Np, Am and Tc onto FHOs under different conditions (pH, radionuclide concentration, solution ion strength, sorbent loading, partial pressure of CO(2) (P CO(2)), equilibrium time) pertinent to environmental and engineered systems, and (2) to provide a microscopic or molecular-level understanding of the chemical speciation and sorption processes of these radionuclides to FHOs.

(super 129) I is present at elevated levels in the surface soils of the Savannah River Site (SRS) F-Area and was found to be bound predominantly to soil organic matter (SOM). Naturally bound (super 127) I and (super 129) I to sequentially extracted humic acids (HAs), fulvic acids (FAs) and a water extractable colloid (WEC) were measured in a (super 129) I-contaminated wetland surface soil located on the SRS. WEC is a predominantly colloidal organic fraction obtained from soil re-suspension experiments to mimic the fraction that may be released during groundwater exfiltration, storm water or surface runoff events. For the first time, NMR techniques were applied to infer the molecular environment of naturally occurring stable iodine and radioiodine binding to SOM. Iodine uptake partitioning coefficients (K (sub d) ) by these SOM samples at ambient iodine concentrations were also measured and related to quantitative structural analyses by (super 13) C DPMAS NMR and solution state (super 1) H NMR on the eight humic acid fractions. By assessing the molecular environment of iodine, it was found that it was closely associated with the aromatic regions containing esterified products of phenolic and formic acids or other aliphatic carboxylic acids, amide functionalities, quinone-like structures activated by electron-donating groups (e.g., NH (sub 2) ), or a hemicellulose-lignin-like complex with phenyl-glycosidic linkages. However, FAs and WEC contained much greater concentrations of (super 127) I or (super 129) I than HAs. The contrasting radioiodine contents among the three different types of SOM (HAs, FAs and WEC) suggest that the iodine binding environment cannot be explained solely by the difference in the amount of their reactive binding sites. Instead, indirect evidence indicates that the macro-molecular conformation, such as the hydrophobic aliphatic periphery hindering the active aromatic cores and the hydrophilic polysaccharides favoring the access by hydrophilic iodine species, also influences iodine-SOM interactions.

The existence of soft zones was identified in the early 1950s, prior to construction of critical nuclear facilities; subsequently, various approaches have been employed to resolve or accommodate the potential for undesirable deep foundation conditions. Investigation into their distribution, occurrence, origin, and behavior suggests that: Soft zones result from early diagenetic carbonate dissolution. Soft zones are not cavernous voids, but are isolated, poorly connected three-dimensional features filled with loose, fine-grained sediment. In spite of their underconsolidated nature, soft zones have survived through geologic time (tens of thousands of years), withstanding numerous seismic events and maintaining structural competence under significant overburden stresses. Elsewhere in the region, solution tunnels and small caves have been discovered in equivalent or similar middle Eocene strata. The existence of soft zones and karst features has important land use, construction, and groundwater hydraulic implications. The evidence collected during more than 60 years of soft zone research suggests that, in most scenarios, soft zones and even some karst conditions can be accommodated with adequate geotechnical characterization, conservative engineering calculations, and appropriate design elements.

New techniques in the past decade (i.e., RTK GPS, VRS networks, multibeam sonars, high-precision echo sounders, high-resolution numerical models) now provide a means to gather detailed geomorphological observations and document fine-scale conditions within salt marsh environments, although questions remain about the utility of some of these methods (i.e., LiDAR). Groves Creek marsh near Savannah, GA, was mapped during 2011-2012 at cm-scale resolution (2.7 M points), using the techniques described above. Comparison of RTK groundtruth and LiDAR performance in salt marshes demonstrates that the highest vertical errors are located in the non-platform, creek and levee zone where taller, more dense grass is observed (mean difference = 0.07 m, RMSE = 0.14 m). On the marsh platform where grasses are sparse, LiDAR-derived elevations were generally in good agreement with RTK-surveyed elevations (mean difference = 0.00 m, RMSE = 0.06 m), suggesting that LiDAR can be useful in salt marsh settings. Groves Creek marsh is typical of Spartina alterniflora salt marshes of the southeastern US, with a main subtidal channel, numerous intertidal channels and broad, vegetated, intertidal marsh platforms. Dynamical processes move water and sediment within this system semidiurnally; dye studies and numerical modeling demonstrate that dissolved constituents are detained by the marsh on weekly timescales and follow flow paths that can only be reasonably delineated using realistic morphologic data. Geologic and microfossil evidence suggests that environmental conditions have changed significantly over the past few thousand years as the estuarine marshes have developed, creating a distinct fining-upward sequence from a combination of allochthonous and autochthonous materials. The upper meter of the marsh reflects conditions closer to those at present: textural composition of 5%, 25% and 70% sand, silt and clay, respectively, carbonate content of 10-20%, short-term ( (super 7) Be) and long-term ( (super 210) Pb) accumulation rates of 0.1-1 cm/y and delta (super 13) C values (-17 to -20ppm) reflecting the strong S. Alterniflora input.

At the F Area within the Savannah River Site, Pu was extracted from depleted U from 1955 to 1988, with wastewater discharged into seepage basins. Basin 3 was the largest F-Area seepage basin, receiving acidic wastewater containing radionuclides (including (super 3) H, (super 129) I, and multiple isotopes of U, Pu, Sr, and Cs), elevated NO (sub 3) , and some metals. Contaminants transported into the groundwater migrate toward Fourmile Branch, a tributary to the Savannah River. We developed a two-compartment model and used 20 yr of groundwater quality data to estimate the post-closure drainage of waste solutions through its vadose zone into the aquifer. Tritium, NO (sub 3) (super -) , and specific conductance were used as tracers in the model to estimate drainage rates. Our calculations indicate that early stages of post-closure waste drainage occurred with high water fluxes (approximately 0.5 m yr (super -1) ) and quickly declined. Even 20 yr after basin closure, however, drainage continues at several centimeters per year. While the magnitude of this late-stage drainage rate is low, its impact is large because of the high concentrations of contaminants it continues to supply to the groundwater. These estimated drainage fluxes constrain predictions on the waste plume behavior, especially with respect to its trailing gradient and time scales suitable for monitored natural attenuation. Our methodology requires only groundwater monitoring data and a small number of well-constrained input quantities. This approach can be useful for understanding contaminant dissipation at other locations as well, especially where the hydrogeological setting is relatively simple.

RadBall registered is a novel, passive, radiation detection device that provides a 3-D visualization of radiation from areas where measurements have not been previously possible due to lack of access or extremely high radiation doses. This technology has been under development during recent years, and all of its previous tests have included dry deployments. This study involved, for the first time, underwater RadBall registered deployments in hot cells containing super(137)CsCl capsules at the U.S. Department of Energy's Hanford Site. RadBall registered can be used to characterize a contaminated room, hot cell, or glovebox by providing the locations of the radiation sources and hazards, identifying the radionuclides present within the cell, and determining the radiation sources' strength (e.g., intensities or dose rates). These parameters have been previously determined for dry deployments; however, only the location of radiation sources and hazards can be determined for an underwater RadBall registered deployment The results from this study include 3-D images representing the location of the radiation sources within the Hanford Site cells. Due to RadBall registered 's unique deploy ability and non-electrical nature, this technology shows significant promise for future characterization of radiation hazards prior to and during the decommissioning of contaminated nuclear facilities.

The method involves a sequence of steps including acidification, evaporation, and precipitation or centrifugation that are performed under defined conditions, and results in a relatively pure, solid lignin product. The method is tested on ammonium hydroxide solutions containing lignin extracted from switchgrass. Experimental results show that the method is capable of recovering between 66-95% of dissolved lignin as a precipitated solid. Cost estimates of pilot-scale and industrial-scale expressions of the process indicate that breakeven lignin prices of $2.36/kg and $0.78/kg, respectively, may be obtainable with this recovery method. copyright 2011 American Institute of Chemical Engineers Environ Prog, 2012 JF - Environmental Progress & Sustainable Energy AU - Sherman, Steven R AU - Goodell, John J AU - Milliken, Charles E AU - Morris, Jacob A AU - Gorensek, Maximilian B AD - Hydrogen and Alternative Energy Programs Department, Savannah River National Laboratory, 773-42A, Aiken, South Carolina 29808.

Successful tritium sequestration in situ will make it possible to maximize the heat values available for hydrogen production and other commercial applications in NGNP systems. In addition, tritium collection and confinement is required from next generation fusion machines where a highly tritiated water (HTW) stream could be generated in such processes like vacuum vessel wall conditioning, and cryopump regeneration. This presentation outlines the synthesis and characterization of perovskite based (ABO3) proton conducting ceramic materials for use as hydrogen isotope gas separation membranes and high temperature solid oxide electrolysis cells.

However, several challenges prevent Li/air batteries from practical application. The oxygen reduction and evolution both take place on the cathode and the effective and long-lasting bifunctional cathodes have not been developed yet. In order to reduce the products of the discharge, effective catalysts have to be developed. To prevent volatile reaction of Li with water, the Li/air batteries have to use non-aqueous electrolyte or use dual electrolyte. The products of discharge, Li(2)O(2) and Li(2)O are not soluble in the non-aqueous electrolyte currently used by researchers.

The device consists of a colander-like outer tungsten collimator that houses a radiation-sensitive polymer semisphere. The collimator has a number of small holes; as a result, specific areas of the polymer are exposed to radiation, becoming increasingly more opaque in proportion to the absorbed dose. The polymer semisphere is imaged in an optical computed tomography scanner that produces a high resolution three-dimensional map of optical attenuation coefficients. A subsequent analysis of the optical attenuation data, using a reverse ray tracing technique, provides information on the spatial distribution of gamma-ray sources in a given area, forming a three-dimensional characterization of the area of interest. The RadBall technology and its reverse ray tracing technique were investigated using known radiation sources at the Savannah River Site's Health Physics Instrument Calibration Laboratory and unknown sources at the Savannah River National Laboratory's Shielded Cells facility.

Vegetation and soil samples were collected from a U processing facility. The water-way fed from facility storm and processing effluents was the focal sample site as it represented a primary U transport mechanism. Soils and sediments from areas exposed to contamination possessed U concentrations that averaged 630 mg U kg super(-1). Aquatic mosses proved to be exceptional accumulators of U with dry weight (dw) concentrations measuring as high as 12 500 mg U kg super(-1) (approximately 1% of the dw mass was attributable to U). The macrophytes (Phragmites communis, Scripus fontinalisand Sagittaria latifolia) were also effective accumulators of U. In general, plant roots possessed higher concentrations of U than associated upper portions of plants. For terrestrial plants, the roots of Impatiens capensishad the highest observed levels of U accumulation (1030 mg kg super(-1)), followed by the roots of Cyperus esculentusand Solidago speciosa.The concentration ratio (CR) characterized dry weight (dw) vegetative U levels relative to that in associated dw soil. The plant species that accumulated U at levels in excess of that found in the soil were: P. communisroot (CR, 17.4), I. capensisroot (CR, 3.1) and S. fontinaliswhole plant (CR, 1.4). Seven of the highest ten CR values were found in the roots. Correlations with concentrations of other metals with U were performed, which revealed that U concentrations in the plant were strongly correlated with nickel (Ni) concentrations (correlation: 0.992; r-squared: 0.984). Uranium in plant tissue was also strongly correlated with strontium (Sr) (correlation: 0.948; r-squared: 0.899). Strontium is chemically and physically similar to calcium (Ca) and magnesium (Mg), which were also positively-correlated with U. The correlation with U and these plant nutrient minerals, including iron (Fe), suggests that active uptake mechanisms may influence plant U accumulation.

2014-003535 AB - Most of the Rb and nearly all of the Cs in near-surface soils of the Savannah River Site (SRS) appear to be fixed in interlayer wedge zones within hydroxy-interlayered vermiculite (HIV) particles [1]. To further investigate this idea, we studied the equilibration of added, highly enriched (super 85) Rb with natural soil Rb under mildly acidic and mildly basic conditions. Consistent results from four soil samples in acidic suspension show equilibration of the added (super 85) Rb with from 4% to 6% of the soil Rb in one day, followed by continued slow equilibration until after two months about twice as much of the soil Rb had equilibrated with the added (super 85) Rb. Equilibration was faster and continued to greater extent when soil was suspended in NaHCO (sub 3) solution, on average by a factor of about 2 in rate and extent. We attribute the faster and more extensive equilibration in basic suspensions to slight expansion of the vermiculite interlayers, and of the adjoining interlayer wedges, as hydrated Na ions replaced the natural exchangeable acidity and as hydroxy-Al polymers were neutralized. Data obtained earlier by Goto et al. [2] show that equilibration of natural soil Cs with (super 137) Cs proceeds more rapidly and is more extensive than what we observed for Rb. Up to 20% of the soil Cs equilibrated with the added (super 137) Cs under mildly acidic conditions, and up to about 50% under mildly basic conditions, in just four days. We interpret the more rapid and more extensive equilibration of Cs than Rb with an added isotope to indicate that Rb is more deeply entrenched in interlayer wedges of HIV than is Cs, because Rb ions are smaller than Cs ions. This interpretation is in accord with results of another experiment in which we found that added Mg, whose hydrated ions keep vermiculite interlayers expanded, strongly enhances the rate of acid extraction of Cs from SRS soils but has little effect on the rate of extraction of Rb.

Waste plumes containing low-level radioactivity and acidic waste solutions were discharged to a series of unlined seepage basins in the F-Area of the SRS from 1955 to 1988. Although the site has undergone many years of active remediation, the groundwater remains acidic, and the concentrations of U and other radionuclides are still significantly higher than their Maximum Contaminant Levels (MCLs). The objective of this effort is to understand and predict U(VI) mobility in acidic waste plumes through developing surface complexation models (SCMs). Laboratory batch experiments were conducted to evaluate U adsorption behavior over the pH range of 3.0 to 9.5. Ten sorbent samples were selected including six contaminated sediment samples from three boreholes drilled within the plume and along the groundwater flow direction, two uncontaminated (pristine) sediment samples from a borehole outside of the plume, and two reference minerals, goethite and kaolinite (identified as the dominant minerals in the clay size fraction of the F-Area sediments). The results show that goethite and kaolinite largely control U partitioning behavior. In comparison with the pristine sediment, U(VI) adsorption onto contaminated sediments exhibits adsorption edges shifted toward lower pH by about 1.0 unit (e.g., from pH nearly equal 4.5 to pH nearly equal 3.5). We developed a SCMs based component additivity (CA) approach, which can successfully predict U(VI) adsorption onto uncontaminated SRS sediments. However, application of the same SCMs based CA approach to contaminated sediments resulted in underestimates of U(VI) adsorption at acidic pH conditions. The model sensitivity analyses indicate that both goethite and kaolinite surfaces co-contributed to U(VI) adsorption under acidic pH conditions. In particular, the exchange sites of clay minerals might play an important role in adsorption of U(VI) at pH < 5.0. These results suggested that the contaminated sediments might either contain other more reactive clay minerals such as smectite, or that the long-term acid-leaching process might have altered the surface reactivity of the original sediments. Further studies are needed to identify more reactive mineral facies and understand the effects of acid leaching on the surface reactivity of the sediments.

Plutonium was extracted from depleted uranium from 1955 to 1988 at the F-Area within the Savannah River Site, with contaminated process waters disposed of in permeable seepage basins. The primarily acidic solutions contained radioactive components (including tritium, (super 129) I, and multiple isotopes of U, Pu, Sr, and Cs), elevated nitrate, and some metals (Hg, Pb, Cd). Basin 3 was the largest F-Area seepage basin, covering 2.0 hectare, with the water table typically at about 20 m below the soil surface. The local groundwater flows at an average velocity of 200 m/y in the approximately 10 m thick shallow aquifer, and is underlain by the low permeability Tan Clay. We used nearly 20 years of groundwater quality data from a monitoring well immediately downstream of Basin 3 to estimate the post-closure drainage of waste solutions through its underlying vadose zone, into the shallow aquifer. The measurements of tritium, nitrate, and specific conductance, were used as plume tracers in our estimates of vadose zone drainage. These calculations indicate that early stages of post-closure waste drainage occurred with high fluxes ( nearly equal 1 m/y), and quickly declined. However, even after 20 years, drainage continues at a low but significant rate of several cm/y. These estimated drainage fluxes can help constrain predictions on the waste plume behavior, especially with respect to its emerging trailing gradient and anticipated time scales suitable for monitored natural attenuation.

Many amendment-based approaches have been successful in saturated formations, however, have not been widely pursued when treating contaminated unsaturated materials due to amendment distribution limitations. Aerosol delivery is a promising new approach for distributing amendments in contaminated vadose zones. Amendments are aerosolized and injected through well screens. During injection the aerosol particles are transported with the gas and deposited on the surfaces of soil grains. Resulting distributions are radially and vertically broad, which could not be achieved by injecting pure liquid-phase solutions. The objectives of this work were A) to characterize transport and deposition behaviors of aerosols; and B) to develop capabilities for predicting results of aerosol injection scenarios. Aerosol transport and deposition processes were investigated by conducting lab-scale injection experiments. These experiments involved injection of aerosols through a 2m radius, sand-filled wedge. A particle analyzer was used to measure aerosol particle distributions with time, and sand samples were taken for amendment content analysis. Predictive capabilities were obtained by constructing a numerical model capable of simulating aerosol transport and deposition in porous media. Results from tests involving vegetable oil aerosol injection show that liquid contents appropriate for remedial applications could be readily achieved throughout the sand-filled wedge. Lab-scale tests conducted with aqueous aerosols show that liquid accumulation only occurs near the point of injection. Tests were also conducted using 200 g/L salt water as the aerosolized liquid. Liquid accumulations observed during salt water tests were minimal and similar to aqueous aerosol results. However, particles were measured, and salt deposited distal to the point of injection. Differences between aqueous and oil deposition are assumed to occur due to surface interactions, and susceptibility to evaporation of aqueous aerosols. Distal salt accumulation during salt water aerosol tests suggests that solid salt forms as salt water aerosols evaporate. The solid salt aerosols are less likely to deposit, so they travel further than aqueous aerosols. A numerical model was calibrated using results from lab-scale tests. The calibrated model was then used to simulate field-scale aerosol injection. Results from field-scale simulations suggest that effective radii of influence on the scale of 8-10 meters could be achieved in partially saturated sand. The aerosol delivery process appears to be capable distributing oil amendments over considerable volumes of formation at concentrations appropriate for remediation purposes. Thus far, evaporation has limited liquid accumulation observed when distributing aqueous aerosols, however, results from salt water experiments suggest that injection of solid phase aerosols can effectively distribute water soluble amendments (electron donor, pH buffer, oxidants, etc.). Utilization of aerosol delivery could considerably expand treatment options for contaminated vadose zones at a wide variety of sites.

Techniques for managing, analyzing, and assessing the data are needed. There is a wealth of data and experience to be leveraged from the study of existing DOE sites such as the Savannah River Site (SRS). A new data management system is being developed as part of the Advanced Simulation Capability for Environmental Management (ASCEM) program to allow faster access to data and a more unified framework to address the challenges of site selection and environmental management. The monitoring network of 274 wells surrounding the F-area recorded 350000 data points over a period of almost 60 years. This data management system was developed for data mining, visualization and exploration and was used for F-area groundwater plume mass balance calculations. Process operations at the F-area led to the discharge of more than 12X10 (super 6) m (super 3) of low-level liquid radioactive waste solutions containing tritium, uranium and fission products into the seepage basins. Between 1953 and 1989, 14 10 (super 4) Ci (corrected for evaporation and decay to 1989) of tritium was released into the basins according to operational data. Starting in the 1950s, SRS monitored radioactivity in Fourmile Branch (FMB) located downgradient of the basins. Through 1989 a total of 5 10 (super 4) Ci (decay-corrected to 1989) was detected in FMB, leaving an estimated inventory of 9 10 (super 4) Ci in the subsurface as of 1989. The sources of uncertainty in the mass balance calculations are discussed and compared with the tritium inventory determined from groundwater monitoring data prior to remediation.

AN - 921714083; 2012-022224 AB - (super 129) I is one of the three major radiation risk contributors to the public as a consequence of past nuclear processing activities at Department of Energy (DOE) facilities. Elevated levels of (super 129) I are present in the surface soils of F-Area of Savannah River Site, which used to be an isotope separation facility for the production of nuclear weapons components. The (super 129) I in soils is thought to be bound predominantly to soil organic matter (SOM). Measurements of stable (super 127) I and radioactive (super 129) I in humic acids (HAs) and fulvic acids (FAs) obtained by five successive alkaline, two glycerol and one citric acid-alkaline extraction, demonstrated that these extractable humic substances (HS) together account for 54-56% and 46% of the total (super 127) I and (super 129) I in the soil, respectively. The remainder was likely bound to residual SOM. The iodine content (mu g-I/g-C) generally decreased with each subsequent extract, while (super 129) I/ (super 127) I increased concurrently. The coincident variations in chemical compositions, aromaticity (estimated by UV spectroscopy), functional groups (e.g., aliphatic), degree of humification, relative migration in the hydrophobic interaction column, and molecular weight indicated that: (1) iodine in different HAs was bound to a small-size aromatic subunit ( approximately 10 kDa); (2) the large-size subunit ( approximately 90 kDa), which likely linked the small-size unit through some weak chemical forces (hydrogen bonds, hydrophobic or electrostatic interactions), determined the relative mobility of iodine bound to organic matter; (3) from the strong correlation between iodine content and aromaticity in the HAs, we suggested that iodine incorporation into the SOM via covalent aromatic C-I bond is the key mechanism controlling iodine behavior in this system. However, this relationship is not universal for all fractions of organic matter as evidenced from the different slopes of this relationship at the two sampling sites, as well as from the different relationships for HAs and FAs, respectively. These differences in iodination are due to different SOM molecular sizes, compositions, and availability of preferred iodination sites. (super 129) I in the soil downstream from the contaminated site and near a wetland abruptly dropped below our detection limit (0.5pCi- (super 129) I/g-soil), which suggests that the high SOM in the plume soil around the (super 129) I-contaminated F-Area might be a natural barrier to scavenge radioiodine released from the nuclear waste repository by forming organo-iodine compounds. Soil resuspension experiments showed that mobile (super 129) I was mostly associated with a low average molecular weight amphiphilic organic carrier (13.5-15 kDa). SOM clearly behaves as a sink for iodine at the Savannah River Site F-Area. However, this work demonstrates that a small fraction of the SOM can also behave as a source, namely that a small fraction that may be readily dispersible under some environmental conditions and presumably release iodine in the organic-colloidal form. This radioiodinated organo-colloid likely can get into the groundwater through infiltration or surface runoff where it might migrate further into the wetlands. Results from this study provide the geochemical basis for future (super 129) I migration controls, remediation, and/or land-groundwater management strategies.

This paper addresses studies of radioactive contamination of the terrestrial faunal complex and radionuclide concentration ratios in bodies of small birds, small mammals, amphibians, and reptiles living in the area. The data were used to calculate doses to biota using the ERICA Tool software. Doses from super(90)Sr and super(137)Cs were calculated using the default parameters of the ERICA Tool and were shown to be consistent with biota doses calculated from the field data. However, the ERICA dose calculations for plutonium isotopes were much higher (2-5 times for small mammals and 10-14 times for birds) than the doses calculated using the experimental data. Currently, the total doses for the terrestrial biota do not exceed maximum recommended levels. However, if the Cooling Pond is allowed to draw down naturally and the contaminants of the bottom sediments are exposed and enter the biological cycle, the calculated doses to biota may exceed the maximum recommended values. The study is important in establishing the current exposure conditions such that a baseline exists from which changes can be documented following the lowering of the reservoir water. Additionally, the study provided useful radioecological data on biota concentration ratios for some species that are poorly represented in the literature.

The article addresses the long-term (1986-2005) and seasonal dynamics of radioactive contamination of animals and reviews interspecies differences in radionuciide accumulations and factors affecting the radionuciide accumulations. It is shown that bioavailability of radionuclides in the "soil-to-plant" chain and a trophic specialization of animals play key roles in determining their actual contamination levels. The total absorbed dose rates in small mammals significantly reduced during the years following the Chernobyl Nuclear Power Plant accident. In 1986, the absorbed dose rate reached 1.3-6.0 Gy h super(-1) in the central areas of the Chernobyl Exclusion Zone (the "Red Forest"). In 1988 and 1990, the total absorbed dose rates were 1.3 and 0.42 Gy h super(-1), respectively. In 1995,2000, and 2005, according to the present study, the total absorbed dose rates rarely exceeded 0.00023, 0.00018, and 0.00015 Gy h super(-1), respectively. Contributions of individual radiation sources into the total absorbed dose are described.

The sampled components included soils (top 0-10 cm depth), Molina caerulea (blue moor grass), Camponotus vagus (carpenter ants), and Pelobates fuscus (spade-footed toad). In a comparison among the components of this ecosystem, the super(90)Sr and super(137)Cs concentrations measured in 40 separate grids exhibited significant differences, while the frequency distribution of the values was close to a logarithmically-normal leptokurtic distribution with a significant right-side skew. While it is important to identify localized areas of high contamination or "hot spots", including these values in the arithmetic mean may overestimate the exposure risk. In component sample sets that exhibited logarithmically normal distribution, the geometric mean more accurately characterizes a site. Ideally, risk assessment is most confidently achieved when the arithmetic and geometric means are most similar, meaning the distribution approaches normal. Through bioaccumulation, the highest concentrations of super(90)Sr and super(137)Cs were measured in the blue moor grass and spade-footed toad. These components also possessed distribution parameters that shifted toward a normal distribution.

The experimental plan included over 1,100 young trees (up to 20 y old) selected from areas with varying levels of radioactive contamination. These pine trees were planted after the 1986 Chernobyl Nuclear Power Plant accident mainly to prevent radionuclide resuspension and soil erosion. For each tree, the major morphological parameters and radioactive contamination values were identified. Cytological analyses were performed for selected trees representing all dose rate ranges. A specially developed dosimetric model capable of taking into account radiation from the incorporated radionuclides in the trees was developed for the apical meristem. The calculated dose rates for the trees in the study varied within three orders of magnitude, from close to background values in the control area (about 5 mGy y super(-1)) to approximately 7 Gy y super(-1) in the Red Forest area located in the immediate vicinity of the Chernobyl Nuclear Power Plant site. Dose rate/effect relationships for morphological changes and cytogenetic defects were identified, and correlations for radiation effects occurring on the morphological and cellular level were established.

On the one hand, this capability can be used potentially in bio-remediation technologies, and on the other hand, it requires additional, more thorough studies to identify its underlying mechanisms. Practically, no data are currently available on mechanisms for implementation of these radioadaptive properties by microscopic fungi. The objective of the completed study was to evaluate the functioning of the antioxidant system of a microscopic fungus as one of potential mechanisms for implementation of its radioadaptive properties. The study was performed using a model system simulating the soil radioactivity in the 5-km zone around the Chernobyl Nuclear Power Plant, with the ratio of the radioactive isotopes matching the radionuclide content in the fuel component of the Chernobyl fallout. The completed study was the first ever performed to identify a comprehensive response of the major components of the antioxidant system of the microscopic fungi to ionizing radiation, resulting in an induced melanin synthesis and increased activity of the known enzymes of antioxidant protection. Their response to ionizing radiation depended on the presence or absence of radioadaptive properties and phase of the fungal growth. Fungi with radioadaptive properties have a much higher susceptibility for inducing synthesis of melanin and antioxidant enzymes than fungi without radioadaptive properties (hereinafter referred to as the reference species or strains), which illustrates the contribution of these processes to "radiophilia" of the fungi.

Isotopic ratios for cesium, europium, plutonium, americium, and curium were identified, and the fuel burn-up in these samples was determined. A systematic deviation in the burn-up values based on the cesium isotopes in comparison with other radionuclides was observed. The studies conducted were the first ever performed to demonstrate the presence of significant quantities of super(242)Cm and super(243)Cm. It was determined that there was a systematic underestimation of activities of transuranic radionuclides in fuel samples from inside of the ChNPP Confinement Shelter, starting from super(241)Am (and going higher) in comnarison with the theoretical calculations.

Measurements were made by gamma spectrometric methods using high purity germanium (HPGe) detectors with beryllium windows. Alpha-emitting isotopes of plutonium were determined by the measurement of the x-rays from their uranium progeny. The presence of super(60)Co, super(134,137)Cs, super(154,155)Eu and super(241)Am in all soil layers down to a depth of 30 cm was observed. The presence of super(137)Cs and super(241)Am was noted in the area containing automorphous soils to a depth of 60 cm. In addition, the upper. soil layers at the test site were found to contain super(243) Am and super(243)Nm. Over the past 10 years, the super(241)Am/ super(137)Cs ratio in soil at the experimental site has increased by a factor of 3.4, nearly twice as much as would be predicted based solely on radioactive decay. This may be due to "fresh" fallout emanating from the ChNPP Confinement Shelter.

In fact, as model complexity continues to grow, we are likely approaching the barrier of "mathematical chaos" wherein model output can no longer conform to the unique reality of the natural system being simulated (classical prediction fails). Thus, the question arises, how can we use mathematical models of increasing complexity to truly increase our understanding of natural systems'? We believe that the answer involves bringing the scientific method (verification by experiment) back into the knowledge-generating process, and using the computer not for classical prediction but to extend our ability to think and hypothesize about complex natural systems (computer-aided thinking). Such an approach is illustrated by an analysis of Pu lysimeter experiments at the Savannah River Site which showed anomalous Pu distributions below the source with unexplained above source migration. The initial conceptual model of the transport process was based on steady-state and then fully transient soil water movement coupled to surface reactions between reduced and oxidized Pu species. Simulations yielded reasonable below-source distributions, but little above-source transport. The conceptual model was then modified to include Pu absorption by plant roots (there was lysimeter grass growth) and upward movement in the transpiration stream. Resulting simulations suggested such movement had to be rapid with a Pu accumulation on the soil surface due to annual dieback. Model-motivated isotope ratio analysis then verified such a residue. Thus, there was strong support for plants being an important pathway for Pu transport, but not a clear picture of the biochemistry involved. This further motivated laboratory experiments on corn that verified rapid Pu transport in the transpiration stream and probable involvement of Pu chelating agents. Data suggest that corn may co-metabolize Pu with Fe, an essential nutrient, thereby increasing greatly the mobility of complexed Pu in plant tissue. In the case of deterministic chaos, the only way forward may be model extrapolation from a data set (not prediction) followed by experimental exploration of the results.

Amongst the plant species sampled were: atmospheric elemental accumulators (moss and lichen), the very slow growing, long-lived creosote bush and the rapidly growing, short-lived cheatgrass brome. The diversity of growth strategies provided insight into the geochemical behavior and bio-availability of Pu at the N2S2. The highest concentrations of Pu were measured in the onion moss (24.27 Bq kg-1 238Pu and 52.78 Bq kg-1 239 + 240Pu) followed by the rimmed navel lichen (8.18 Bq kg-1 and 18.4 Bq kg-1 respectively), pointing to the importance of eolian transport of Pu. Brome and desert globemallow accumulated between 3 and 9 times higher concentrations of Pu than creosote and sage brush species. These results support the importance of species specific elemental accumulation strategies rather than exposure duration as the dominant variable influencing Pu concentrations in these plants. Total vegetation elemental concentrations of Ce, Fe, Al, Sm and others were also analyzed. Strong correlations were observed between Fe and Pu. This supports the conclusion that Pu was accumulated as a consequence of the active accumulation of Fe and other plant required nutrients. Cerium and Pu are considered to be chemical analogs. Strong correlations observed in plants support the conclusion that these elements displayed similar geochemical behavior in the environment as it related to the biochemical uptake process of vegetation. Soils were also sampled in association with vegetation samples. This allowed for the calculation of a concentration ratio (CR). The CR values for Pu in plants were highly influenced by the heterogeneity of Pu distribution among sites. Results from the naturally occurring elements of concern were more evenly distributed between sample sites. This allowed for the development of a pattern of plant species that accumulated Ce, Sm, Fe and Al. The highest accumulators of these elements were onion moss, lichen flowed by brome. The lowest accumulators were creosote bush and fourwing saltbush. This ranked order corresponds to plant accumulations of Pu.

Currently, little is known about radionuclide penetration into construction materials in an urban environment. Knowledge in this area would be useful when considering costs of a thorough decontamination of buildings, artificial structures and roads in an affected urban environment. Pripyat, a city substantially contaminated by the Chernobyl Nuclear Power Plant accident in April 1986, may provide some answers. The main objective of this study was to assess the depth of super(90)Sr and super(137)Cs penetration into reinforced concrete structures in a highly contaminated urban environment under natural weather conditions. Thirteen reinforced concrete core samples were obtained from external surfaces of a contaminated building in Pripyat. The concrete cores were drilled to obtain sample layers of 0-5, 5-10, 10-15, 15-20, 20-30, 30-40 and 40-50 mm. Both super(90)Sr and super(137)Cs were detected in the entire 0-50 mm profile of the reinforced cores sampled. In most of the cores, over 90% of the total super(137)Cs inventory and 70% of the total super(90)Sr inventory was found in the first 0-5 mm layer of the reinforced concrete.

However, at elevated temperatures and extended operation times structural changes including partial crystallinity may appear in these amorphous metallic systems. This study reports on the investigation of time and temperature dependent crystalline phase formation in conjunction with in situ crystallization/hydrogen permeation experiments at elevated temperatures. At temperatures near 400 degree C a FeNi crystalline phase appears as 22 vol.% inside the host amorphous matrix and the resulting composite structure remains stable over 3 h at temperature. The hydrogen permeation at 400 degree C of the partially crystalline material is similar to the fully amorphous material near 5 x 10 super(-9 mol H) sub(2)/m s Pa super(1/2, while ambient temperature electrochemical permeation at 25 degree C revealed an order of magnitude decrease in the permeation of partially crystalline materials due to differences in the amorphous versus crystalline phase activation energy for hydrogen permeation.)

According to the 2001 data, the measured radionuclide inventory in the ChNPP Cooling Pond bottom deposits was as follows: 16.28 plus or minus 2.59 TBq for super(137)Cs; 2.4 plus or minus 0.48 TBq for super(90)Sr, and 0.00518 plus or minus 0.00148 TBq for super(239+240)Pu. Because all ChNPP reactors are now shutdown, the Cooling Pond is no longer needed and is currently in the process of being decommissioned. Due to its large size, it is not cost effective to maintain it in the long term. However, the natural drawdown of the reservoir following shutdown of the water feed to the Cooling Pond would expose the contaminated bottom deposits and change the hydrological features of the area, thus destabilizing the radiological and environmental situation in the entire region. The ChNPP Cooling Pond and its shoreline areas present a complex ecosystem in the succession phase with well-established radioecological properties associated with the accidental contamination. The assessment of the current radioecological situation indicates its relative stability and predictability. However, evaporation of the Cooling Pond will destabilize the radioecological situation and increase risks for the biota. According to the preliminary estimates, the total doses for various animal species (mammals and reptilians) may exceed the maximum allowable doses that are currently considered safe by a factor of several times. Analysis of a possible strategy for the Cooling Pond decommissioning shows that the best option would be its natural evaporation and drainage accompanied by a continuous radioecological monitoring and, if necessary, taking steps for an expedited recovery of vegetation in the exposed areas. Since the radioactive contamination is unevenly distributed in the area, the data on the shoreline biota contamination obtained so far should be considered preliminary and insufficient for an adequate radioecological assessment of the Cooling Pond evaporation and drainage. Such studies will have to continue on a larger scale, covering new shoreline areas. Development of a strategy for the Cooling Pond decommissioning and prediction of its potential environmental consequences require a more thorough study of the existing biological speciation and rate of transformation (succession) of the shoreline cenoses. Comprehensive radioecological studies of the Cooling Pond will make it possible to develop recommendations on assessment of radiation characteristics of water reservoirs with residual radioactive contamination and their adequate decommissioning.

To address this need, they worked with key partners from universities across the U.S. and laboratories in France and the Ukraine to form the National Center for Radioecology (NCoRE), a network of excellence for environmental radiation risk reduction and remediation. Focused research areas include; molecular and genetic level effects, synergistic effects, individual and population level studies, ecosystem studies, sequestration and remediation, and homeland security issues related to urban radioecology. A core component of this program will be to make the fundamental connection between environmental health and human health risk assessment. The main objectives of NCoRE are to: 1) foster collaboration among scientists in the DOE complex, Federal agencies, State entities, Universities and International research institutions in the various disciplines of the field of radioecology; 2) Work with key partners to establish a training and educational program to train radioecologists in the United States. Currently there is no formal graduate program in radioecology in the United States and the development of a training program would help to fill the technical information gap needed within the aging DOE workforce and; 3) Leverage resources and expertise to address research and development opportunities through joint proposals both in the United States and internationally. Member organizations of NCoRE currently include: U.S. Department of Energy's Savannah River National Laboratory, Clemson University, Colorado State University, Duke University, Institut De Radioprotection Et De Surete Nucleaire (IRSN, France), International Radioecology Laboratory of the Chernobyl Center (IRL, Ukraine), Oregon State University, University of Georgia - Savannah River Ecology Laboratory, and the University of South Carolina. The member institutions all bring unique contributions to their participation in NCoRE. The academic and research specialties of each of the member institutions of NCoRE will provide the foundation for training the next generation of radioecologists.

Discharges associated with these now-ceased operations have contaminated large areas within the site, particularly streams associated with reactor cooling basins. Evaluating the exposure risk of contamination to an ecosystem requires methodologies that can assess the bioavailability of contaminants. Plants, as primary producers, represent an important mode of transfer of contaminants from soils and sediments into the food chain. The objective of this study was to identify local area plants for their ability to act as bio-monitors of radionuclides. The concentrations of cesium-137 ( super(137)Cs), potassium-40 ( super(40)K), super(238)Pu and super(239,240)pu in plants and their associated soils were determined using gamma and alpha spectrometry. The ratio of contamination concentration found in the plant relative to the soil was calculated to assess a concentration ratio (CR). The highest CR for super(137)Cs was found in Pinus palustris needles (CR of 2.18). The correlation of soil and plant super(137)Cs concentration was strong (0.76) and the R super(2) (0.58) from the regression was significant (p = 0.006). This suggests the ability to predict the degree of super(137)Cs contamination of a soil through analysis of the pine needles. The super(238)Pu and super(239,24O)Pu concentrations were most elevated within the plant roots. Extremely high CR values were found in Sparganium americanum (bur-reed) roots with a value of 5.86 for 238Pu and 5.66 for super(239,240)Pu. The concentration of super(40)K was measured as a known congener of super(137)C. Comparing super(40)K and super(137)C concentrations in each plant revealed an inverse relationship for these radioisotopes. Correlating super(40)K and super(137)Cs was most effective in identifying plants that have a high affinity for super(137)Cs uptake. The P. palustris and S. americanum proved to be particularly strong accumulators of all K congeners from the soil. Some species that were measured, warrant further investigation, are the carnivorous plant Utricularia inflata (bladderwort) and the emergent macrophyte Juncus effusus. For U. inflata, the levels of 137Cs, 238Pu, and 239,240pu (which were 3922, 8399, and 803 Bq kg super(-1), respectively) in the leaves were extremely high. The highest super(137)Cs concentration from the study was measured in the J. effusus root (5721 Bq kg super(-1)).

Because values are commonly reused many times in a single simulation, small errors can be magnified greatly. Goethite (alpha -FeOOH) and pyrolusite (beta -MnO (sub 2) ) are ubiquitous mineral phases that are especially contaminant reactive. The objective of the present study was to measure and compare the point of zero charge (PZC) using different methods. The pyrolusite PZC was measured with three methods: mass titration (MT) (PZC = 5.9 + or - 0.1), powder addition (PA) (PZC = 5.98 + or - 0.08), and isoelectric point, IEP (PZC = 4.4 + or - 0.1). The IEP measurement was in agreement with literature values. However, MT and PA resulted in a statistically larger PZC than the IEP measurement. The surface area of pyrolusite, 2.2 m (super 2) g (super -1) , was too small to permit PZC determination by the potentiometric titration (PT) method. Goethite PZC values were measured using MT (7.5 + or - 0.1), PT (7.46 + or - 0.09), and PA (7.20 + or - 0.08). The present work presents the first reported instance where MT and PA have been applied to measure the point of zero charge of either pyrolusite or goethite. The results illustrate the importance of using multiple complementary techniques to measure PZC values accurately.

14584021 AB - super(129)I is of major concern because of its mobility in the environment, excessive inventory, toxicity (it accumulates in the thyroid), and long half-life ( similar to 16 million years). The aim of this study was to determine if bacteria from a super(129)I-contaminated oxic aquifer at the F area of the U.S. Department of Energy's Savannah River Site, SC, could accumulate iodide at environmentally relevant concentrations (0.1 mu M I super(-)). Iodide accumulation capability was found in 3 out of 136 aerobic bacterial strains isolated from the F area that were closely related to Streptomyces/Kitasatospora spp., Bacillus mycoides, and Ralstonia/Cupriavidus spp. Two previously described iodide-accumulating marine strains, a Flexibacter aggregans strain and an Arenibacter troitsensis strain, accumulated 2 to 50% total iodide (0.1 mu M), whereas the F-area strains accumulated just 0.2 to 2.0%. Iodide accumulation by FA-30 was stimulated by the addition of H sub(2)O sub(2), was not inhibited by chloride ions (27 mM), did not exhibit substrate saturation kinetics with regard to I super(-) concentration (up to 10 mu M I super(-)), and increased at pH values of <6. Overall, the data indicate that I super(-) accumulation likely results from electrophilic substitution of cellular organic molecules. This study demonstrates that readily culturable, aerobic bacteria of the F-area aquifer do not accumulate significant amounts of iodide; however, this mechanism may contribute to the long-term fate and transport of super(129)I and to the biogeochemical cycling of iodine over geologic time.

Acid-base titrations of sediment samples from contaminated aquifers are indicative of the mineral surface properties that control sorption of contaminants. Samples with similar mineralogy will have titration curves with similar shapes and variations in reactive surface area are reflected by shifting locations of titration curve equivalence points. Hence, acid-base titration curves can be a simple cost effective method for distinguishing reactive facies. This study was conducted at the Savannah River Site (SRS). The focus of this study is the contamination plume associated with the F-Area Seepage Basins. The contaminants of primary concern are uranium, (super 129) I, (super 90) Sr, and (super 3) H. The aquifer is sandy with minor clay-sized minerals composed primarily of kaolinite and goethite with smectite being observed in the lower part of the aquifer. Soil core samples were taken from horizons in these basins, at elevations throughout the saturated zone of the core. Titrations were performed using a variation of the back-titration method to account for mineral dissolution and other non-surface effects. The data from this method were used to calculate the soil surface charge. X-ray fluorescence analysis was conducted on core samples from these same locations performed in the back-titration method. This analysis characterized the core's chemical composition. Previously collected X-ray diffraction data was used to identify the mineralogy. Preliminary results of these analyses indicate three groups of similar curves. The mineralogy for these core samples compared to the surface charge suggests a correlation between the titration curves of these reactive facies and their mineralogy. These titration curves aide in the understanding of geochemical heterogeneity in aquifers.

These lithofacies were subdivided into microfacies based on petrographic examination; quartz sand; lime mud, terrigenous mud, microsparite, siliceous mudstone, skeletal quartz sand; quartz-rich skeletal calcareous mud; skeletal wackestone and quartz-rich skeletal wackestone; skeletal packstone and quartz-rich skeletal packstone; quartz-rich, glauconitic skeletal wackestone and packstone; and sandy skeletal grainstone. Carbonate-rich facies are more prevalent downdip, while terrigenous rich facies dominant updip. The transition from terrigenous-rich to carbonate-rich occurs updip in a narrow zone less than 5 km wide. The primary control on areal facies distribution is depositional environment, controlled by sea level eustacy, and amount, rate and locus of terrigenous influx. Petrographic characteristics of the updip microfacies will be presented. Diagenetic pathways vary with facies type, but generally include: (1) marine phreatic - grain micritization, and radially fibrous cementation; (2) freshwater phreatic - inversion of high-Mg calcite to low-Mg calcite, dissolution of aragonitic allochems, formation of moldic porosity, precipitation of syntaxial calcite overgrowths on echinoderms, formation of calcite spar and isopachous calcite cement, neomorphism of micrite to microspar and pseudospar, precipitation of opal-CT lepispheres, replacement of mollusk shells by chalcedony, and precipitation of zeolites within secondary moldic pores. Quartz-rich facies have high interparticle porosity and excellent permeability. Mud-rich facies have low to moderate porosities and permeabilities owing to the isolation of moldic and vug pores. Lithologic and geophysical data for more than 90 boreholes were used in this study. Methods included thin section examination, insoluble residue analysis, and SEM.

Numerous traditional and natural treatment methods, which act to remove copper from the wastewater, were considered including ion exchange, wetlands, and peat bed treatments. The low target copper concentration and highly variable outfall conditions presented a significant challenge for all of the technologies considered. In addition, costs and energy use for most of these alternatives were high and secondary wastes would be generated. The Savannah River National Laboratory (SRNL) developed a new "detoxification" approach to treat the outfall water based on the EPA's Biotic Ligand Model (BLM) and dissolved organic carbon (DOC). The BLM calculates copper toxicity based on water quality parameters such as pH, DOC, and percentage of the DOC. The BLM predicts how DOC in the water binds with copper in the water, limiting the availability of copper to interact with "biotic ligands," and reducing impacts to aquatic organisms. Modeling results from the BLM confirmed that an addition of DOC in concentrations similar to the receiving stream could reduce copper toxicity in the H-12 water allowing the goal of the proposed NPDES permit to be met even if copper is present at concentrations greater than 6 mu g/l. SRNL tested seven organic carbon amendments to determine the best candidates. These products are high in humic compounds or similar molecules and are typically used as soil additives in organic farming. The amendment chosen was a commercial potassium humate. Based on the laboratory tests, SRNL developed a process control equation used in the detoxification system at the H-12 Outfall. The South Carolina Department of Health and Environmental Control approved the treatment concept and allowed the outfall to maintain the 25 mu g/l copper limit. The resulting system includes two double-walled 5500 gal storage tanks, recirculation pumps, pH and flow meters, program logic controllers, and solar panels. The detoxification system, which began operating in June 2009, protects and improves the environment while significantly reducing energy use, land disturbance, and costs, as well as eliminating generation of secondary waste.

Soil vapor extraction was not effective for these tight zones in the coastal plain sediments and the trapped solvents are a slow but continuous source of contamination primarily by gas diffusion. A low cost, sustainable means to sequester and remediate these slowly migrating contaminants in an aerobic vadose zone was needed. cVOCs are easily sequestered by partitioning into edible oils and reductive dechlorination can be established under the correct geochemical conditions. Based on successes of stimulating reductive dechlorination using carbon sources in groundwater systems and the sequestering ability of edible oils, a substrate was developed for the vadose zone. VOS (super TM) (patent pending) is a thixotropic formulation of edible oil, water, nutrients, buffers and a Dehalococcoides strain that is easily injected into the vadose zone and then retains a high saturation to maintain reducing conditions. A field pilot study is being conducted to evaluate the effectiveness and longevity of the VOS deployment to mitigate the cVOC contamination. In February 2010, approximately 230 gallons of VOS was injected into three injection points installed 30-35 ft deep beneath a tight zone with known PCE and TCE contamination. Twenty gas sample ports were installed in the injection zone and deeper into the vadose zone for evaluation. Samples are collected weekly and are analyzed for cVOCs and their breakdown products. Additional gas analyses include light hydrocarbons, carbon dioxide and oxygen. Soil cores are collected every six months for analysis of cVOCs and specific geochemical parameters.

These issues include the levels and characteristics of the radioactive contamination, the availability of resources required for decontamination, and the planned future use of the city's structures and buildings. Presently, little is known about the distribution, redistribution, and migration of radionuclides in an urban environment. However, Pripyat, a city substantially contaminated by the Chernobyl Nuclear Power Plant accident in April 1986, may provide some answers. The main objective of this study was to determine the radionuclide distribution on a Pripyat multistory building that had not been decontaminated and, therefore, could reflect the initial fallout and its further natural redistribution on external surfaces over 23 y. The seven-story building selected was surveyed from the ground floor to the roof on horizontal and vertical surfaces along seven ground-to-roof transections. Some results from this study indicate that the upper floors of the building had higher contamination levels than the lower floors. Consequently, the authors recommend that thorough decontamination should be considered for all the floors of tall buildings (not just lower floors).

AN - 840349520; 21138294 AB - Field and laboratory studies were carried out to understand the cause for steady increases in (129)I concentrations emanating from radiological basins located on the Savannah River Site, South Carolina. The basins were closed in 1988 by adding limestone and slag and then capping with a low permeability engineered cover. Groundwater (129)I concentrations in a well near the basins in 1993 were 200 pCi L(-1) and are presently between 400 and 1000 pCi L(-1). Iodine speciation in the plume contained wide ranges of iodide, iodate, and organo-iodine concentrations. First-order calculations based on a basin sediment desorption study indicate that the modest increase of 0.7 pH units detected in the study site groundwater over the last 17 years since closure of the basins may be sufficient to produce the observed increased groundwater (129)I concentrations near the basins. Groundwater monitoring of the plume at the basins has shown that the migration of many of the high risk radionuclides originally present at this complex site has been attenuated. However, (129)I continues to leave the source at a rate that may have been exacerbated by the initial remediation efforts. This study underscores the importance of identifying the appropriate in situ stabilization technologies for all source contaminants, especially if their geochemical behaviors differ.

The disposal operations lasted for about 35 years until 1990, when the seepage basins were solidified and capped. Since then, the groundwater pH in the plume has remained mostly in the 3-3.5 range despite the end of disposal operations and fast groundwater velocities, although U concentration adjacent to the basins has been decreasing exponentially. Here, we report on exploratory geochemical and reactive transport modeling investigations conducted to assess the relative roles of surface protonation and mineral precipitation in slowing down the rebound of pH at this site, as well as U transport behavior downgradient of the disposal basins. The modeling work is integrated with investigations of 'reactive facies', which aim at identifying specific types of sediments with unique properties affecting reactive transport, then correlating these sediment types with lithologic facies and their associated geophysical signatures for estimation of reactive properties over plume scales. One- and two-dimensional reactive transport simulations were conducted considering Al and Fe mineral dissolution and precipitation, as well as H (super +) and U surface complexation models from the literature. Simulations indicate that H (super +) sorption reactions on goethite and kaolinite (primary minerals at the site besides quartz) could buffer pH at the site for long periods of time. The precipitation of Al silicates, hydroxides, and/or hydroxy sulfates could also strongly impede pH rebound at the site. Although the pH is computed to rebound quite slowly, U concentrations could potentially decrease at comparatively much faster rates from dilution with clean recharge water. Simulations results are most sensitive to reactive surface areas, to relative rates of reaction versus acidic discharge, to relative rates of mineral precipitation and dissolution, and to the type of implemented sorption models and parameters. The model sensitivity to heterogeneous fields of permeability and reactive surface areas derived from the reactive facies investigations is also investigated.

These disposal activities resulted in a persistent acidic groundwater plume (pH as low as 3.2) beneath the F-Area including contaminants such as (super 3) H, HNO (sub 3) , (super 90) Sr, (super 129) I and U that has impinged on surface water about 600 m from the basins. After cessation of disposal in 1989, the basins were capped in 1991. Since then, remediation consisted of a pump-and-treat system that was recently replaced by in situ treatment using a funnel-and-gate system with injection of alkaline solutions to neutralize pH. In order to delineate the history of contamination and the current mobility and fate of contaminants in F-Area groundwater, we have undertaken a study of variations in the isotopic compositions of U ( (super 234) U/ (super 238) U, (super 235) U/ (super 238) U, (super 236) U/ (super 238) U), Sr ( (super 87) Sr/ (super 86) Sr), Nd ( (super 143) Nd/ (super 144) Nd) water (delta (super 18) O, delta D) and nitrate (delta (super 15) N, delta (super 18) O) within the contaminant plume. The chemical and isotopic variations in the plume all delineate upper (0-15ft below water table) and lower (15-35 ft) zones within the upper aquifer. Together, the data suggest that the lower zone represents the effects of seepage from the basins during operation, while the upper zone represents mostly meteoric water contaminated by infiltration through the sub-basin vadose zone since closure/capping. Through U isotopic analysis, we have been able to detect recent migration as the plume expands laterally, with the greatest extent of U contamination near the top of the aquifer but decreasing with depth. Comparing the U isotopic compositions of groundwater samples collected within the plume two years apart tracks the migration of U from up-gradient portions of the plume. Nd isotopic compositions indicate that REE concentrations were controlled by progressive interaction between acid solutions and natural trace minerals in the sediments. Nitrate has an isotopic signature of processed waste, but no sign of nitrate bioreduction within the plume.

This facility covers similar to 800 square kilometers and is mainly wooded except for scattered industrial areas containing facilities used in managing nuclear materials for national defense and processing waste. Prescribed fires of forest undergrowth are necessary to reduce the risk of inadvertent wild fires which have the potential to destroy large areas and threaten nuclear facility operations. This paper discusses meteorological observations and numerical model simulations from a period in early 2002 when poor visibility along a major roadway on the northern border of the SRS was determined to be the primary cause of an early-morning multi-car accident. This incident was significant because of concerns that the limited visibility was not due solely to the prevailing widespread fog, but that residual smoke from a prescribed burn conducted the previous day just to the northwest of the crash site had enhanced fog density, further reducing local visibility. Through the use of available meteorological information and detailed modeling, it was determined that most of the residual smoke would likely have been transported away from the roadway by the prevailing wind and, therefore, would not have contributed to additional degradation of visibility at the accident site. This event clearly illustrates the need for a careful examination of the characteristics of the fire site (e.g., proximity to roadway, topography, etc.), in conjunction with a forecast for the occurrence of overnight fog, when planning prescribed fires near major roadways.

Different impurities are often present in the feed streams of the process diffusers, but the effect of these impurities on the diffuser performance is currently unknown. Various impurities were introduced into the feed stream of the diffuser at various levels ranging from 0.5% to 10% of the total flow in order to determine the effect that these impurities have on the permeation of hydrogen through the palladium-silver membrane. The introduction of various impurities into the feed stream of the diffuser had a minimal effect on the overall permeation of hydrogen through the Pd-Ag membrane. Of the four impurities introduced into the feed stream, carbon monoxide (CO) was the only impurity that showed any evidence of causing a reduction in the amount of hydrogen permeating through the Pd-Ag membrane. The hydrogen permeation returned to its baseline level after the CO was removed from the feed stream. There were no lasting effects of the CO exposure on the ability of the membrane to effectively separate hydrogen from the non-hydrogen species in the gas stream under the conditions tested.

This paper describes the long-term performance of a constructed wetland for metal removal, including the efficiency of metal removal, and the retention of metals in the wetland sediment. It is based on four years of data collected from the A-01 wetland treatment system, a surface flow wetland planted with Schoenoplectus californicus (giant bulrush). The system is designed to remove Cu and other metals from the A-01 National Pollution Discharge Elimination System (NPDES) outfall effluent at the Savannah River Site near Aiken, SC. Copper, Zn, and Pb concentrations in water were usually reduced 60 to 80% during passage through the A-01 treatment system. Most of the metal removed by the wetland cells was accumulated in the two top layers of the substrate; i.e., the floc and organic layers. This gradient was strongly correlated with percent organic matter, pH, and the concentration of all metals. These results showed that most metals in the A-01 wetland sediments behaved similarly: their concentrations decreased as sediment depth increased.

Significant problems may result from decommissioning of cooling ponds with residual radioactive contamination. The Chernobyl Nuclear Power Plant (ChNPP) Cooling Pond is one of the largest self-contained water reservoirs in the Chernobyl region and Ukrainian and Belorussian Polesye region. The 1986 ChNPP Reactor Unit Number Four significantly contaminated the ChNPP Cooling Pond. The total radionuclide inventory in the ChNPP Cooling Pond bottom deposits are as follows: super(137)Cs: 16.28 plus or minus 2.59 TBq; super(90)Sr: 2.4 plus or minus 0.48 TBq; and super(239+240)Pu: 0.00518 plus or minus 0.00148 TBq. The ChNPP Cooling Pond is inhabited by over 500 algae species and subspecies, over 200 invertebrate species, and 36 fish species. The total mass of the living organisms in the ChNPP Cooling Pond is estimated to range from about 60,000 to 100,000 tons. The territory adjacent to the ChNPP Cooling Pond attracts many birds and mammals (178 bird species and 47 mammal species were recorded in the Chernobyl Exclusion Zone). This article describes several options for the ChNPP Cooling Pond decommissioning and environmental problems associated with its decommissioning. The article also provides assessments of the existing and potential exposure doses for the shoreline biota. For the 2008 conditions, the estimated total dose rate values were 11.4 40 kGy h super(-1) for amphibians, 6.3 kGy h super(-1) for birds, 15.1 kGy h super(-1) for mammals, and 10.3 kGy h super(-1) for reptiles, with the recommended maximum dose rate being equal to 40 kGy h super(-1). However, drying the ChNPP Cooling Pond may increase the exposure doses to 94.5 kGy h super(-1) for amphibians, 95.2 kGy h super(-1) for birds, 284.0 kGy h super(-1) for mammals, and 847.0 kGy h super(-1) for reptiles. All of these anticipated dose rates exceed the recommended values.

Physical degradation occurs as the drill bit grinds through the ore and changes the surface area of the uranium phases. Chemical changes are induced by the introduction of mud, fluid and air during drilling and well development. The increase in surface area of the uranium phases exposed in the drill hole and introduction of oxygen from fluid and air may create a transient signature of redox disequilibrium in the first several rounds of groundwater samples. These changes must be understood and documented before establishing an accurate baseline that can be used in a valid assessment of the environmental impact of uranium in situ recovery (ISR) operations on groundwater quality. A transient redox condition is observed in groundwater samples collected from the proposed uranium ISR project in Goliad, TX. Samples collected over a period of approximately 18 months from monitoring wells placed outside and inside the ore zone show decreasing uranium and/or arsenic concentrations between the first, second, and third rounds of samples. In the ore zone, first round samples show uranium variation from 0.804 to 0.005 mg/L, while third round samples are tightly clustered between 0.010 and 0.005 mg/L. Decreasing uranium values follow solubility curves for uraninite and soddyite as Eh decreases. Samples collected from monitoring wells in the overlying sand outside the ore zone show that the arsenic variation of 0.032 to 0.010 mg/L in Round 1 decreases to 0.010 to 0.005 in Round 3. The anthropogenic disturbance of the ore zone also releases additional radium-226 into the groundwater, and radium-226 remains elevated in subsequent sampling rounds because it is insensitive to redox variation. This example serves to illustrate that conventional drilling and development methods may not produce accurate baseline values for uranium and arsenic until initial redox conditions return. However, once the ore deposit is disturbed, it is unlikely that a true baseline value can be developed for radium-226. Alternate sampling methods (e.g., geoprobe push rods) should be used to collect the most representative sample possible to ensure valid baseline values will be established for important water-quality parameters.

Depth discrete measurements of K (sub d) were made for a suite of radionuclides ( (super 109) Cd, (super 57) Co, (super 60) Co, (super 85) Sr, (super 137) Cs, and (super 88) Y) utilizing a sediment core from the E-Area at the Savannah River Site. The K (sub d) 's were ordered as (super 85) Sr (super 2+) < (super 137) Cs (super +) < (super 109) Cd (super 2+) < (super 57) Co (super 2+) = (super 60) Co (super 2+) << (super 88) Y (super 3+) and the values generally fell below or near the lowest quartile of values reported in the literature. Correlations were generally weak between soil properties and K (sub d) values. Most importantly, all of the K (sub d) distributions could be reasonably approximated as log-normal. Deterministic and stochastic calculations of contaminant travel time to the water table were made. The deterministic calculations were based on each of three conceptual models of the vadose zone: complete stratification (17 strata, each with a different K (sub d) ), two strata (two sections of the vadose zone, each characterized by a single, average K (sub d) ), and unstratified (a single zone with an average K (sub d) ). Stochastic calculations were based on log-normal fits to the K (sub d) data. The two strata model generally yielded travel times 2x greater than those in the completely stratified model. The unstratified model yielded travel times that were between 3 and 5 times greater than the completely stratified model. The stochastic mean travel times were comparable to those of the two strata model. Abstract Copyright (2010) Elsevier, B.V.

They are made by applying chemically active amendments that reduce contaminant mobility and bioavailability to the sediment surface. The objective of this study was to determine if active cap amendments including organoclay, apatite, and biopolymers have the potential to harm benthic organisms. Methods included laboratory bioassays of amendment toxicity and field evaluations of amendment impacts on organisms held in cages placed within pilot-scale active caps located in Steel Creek, a South Carolina (USA) stream. Test organisms included Hyalella azteca, Leptocheirus plumulosus, Lumbriculus variegatus, and Corbicula fluminea to represent a range of feeding modes, burrowing behaviors, and both fresh and saltwater organisms. In addition to the laboratory and field assays, chemical extractions were performed to determine if the amendments contained harmful impurities that could leach into the ambient environment. Laboratory bioassays indicated that 100% apatite had minimal effects on Hyalella in freshwater and up to 25% organoclay was nontoxic to Leptocheirus in brackish water. Field evaluations indicated that pilot-scale caps composed of up to 50% apatite and 25% organoclay did not harm Hyalella, Lumbriculus, or Corbicula. In contrast, organisms in caps containing biopolymers died because of physical entrapment and/or suffocation by the viscous biopolymers. The extractions showed that the amendments did not release harmful concentrations of metals. These studies indicated that apatite and organoclay are nontoxic at concentrations (up to 50% and 25% by weight, respectively) needed for the construction of active caps that are useful for the remediation of metals and organic contaminants in sediments.

The separation processes at SRS include the sorption of 90Sr and alpha-emitting radionuclides onto monosodium titanate (MST) and caustic side solvent extraction of 137Cs. The MST and separated 137Cs is encapsulated along with the sludge fraction of high-level waste (HLW) into a borosilicate glass waste form for eventual entombment at a federal repository. The predominant alpha-emitting radionuclides in the highly alkaline waste solutions include plutonium isotopes 238Pu, 239Pu, and 240Pu; 237Np; and uranium isotopes, 235U and 238U. This article describes recent results evaluating the performance of an improved sodium titanate material that exhibits increased removal kinetics and capacity for 90Sr and alpha-emitting radionuclides compared to the current baseline material, MST.

Krivit and Marwan (J. Environ. Monit., 2009, 11, 1731) give a brief and wholly positive view of this body of research. Unfortunately, cold fusion researchers routinely ignore conventional explanations of their observations, and claim much greater than the real accuracy and precision for their techniques. This paper attempts to equally briefly address those aspects of the field with the intent of providing a balanced view of the field, and to establish some criteria for subsequent publications in this arena.

Intriguingly, the actinobacterium Kineococcus radiotolerans has been shown to not only accumulate soluble copper to high levels within the cytoplasm, but the phenotype also correlated with enhanced cell growth during chronic exposure to ionizing radiation. This study offers a first glimpse into the physiological and proteomic responses of K. radiotolerans to copper at increasing concentration and distinct growth phases. Aerobic growth rates and biomass yields were similar over a range of Cu(II) concentrations (0-1.5 mM) in complex medium. Copper uptake coincided with active cell growth and intracellular accumulation was positively correlated with Cu(II) concentration in the growth medium (R2=0.7). Approximately 40% of protein coding ORFs on the K. radiotolerans genome were differentially expressed in response to the copper treatments imposed. Copper accumulation coincided with increased abundance of proteins involved in oxidative stress and defense, DNA stabilization and repair, and protein turnover. Interestingly, the specific activity of superoxide dismutase was repressed by low to moderate concentrations of copper during exponential growth, and activity was unresponsive to perturbation with paraquot. The biochemical response pathways invoked by sub-lethal copper concentrations are exceptionally complex; though integral cellular functions are preserved, in part, through the coordination of defense enzymes, chaperones, antioxidants and protective osmolytes that likely help maintain cellular redox. This study extends our understanding of the ecology and physiology of this unique actinobacterium that could potentially inspire new biotechnologies in metal recovery and sequestration, and environmental restoration.

Vitrification of this waste into borosilicate glass for ultimate disposal at a geologic repository involves chemically modifying the waste to make it compatible with the glass melter system. Pretreatment steps include removal of excess aluminum by dissolution and washing, and processing with formic and nitric acids to (1) adjust the reduction-oxidation (redox) potential in the glass melter to reduce radionuclide volatility and improve melt rate; (2) adjust feed rheology; and (3) reduce, by steam stripping, the amount of mercury that must be processed in the melter. Elimination of formic acid pretreatment has been proposed to eliminate the production of hydrogen in the pretreatment systems; alternative reductants would be used to control redox. However, elimination of formic acid would result in significantly more mercury in the melter feed; the current specification is no more than 0.45 wt%, whereas the maximum expected before pretreatment is about 2.5 wt%. An engineering study has been undertaken to estimate the effects of eliminating mercury removal on the melter offgas system performance. A homogeneous gas-phase oxidation model and an aqueous phase model were developed to study the speciation of mercury in the DWPF melter offgas system. The model was calibrated against available experimental data and then applied to DWPF conditions. The gas-phase model predicted the Hg(2)(2+)/Hg(2+) ratio accurately, but some un-oxidized Hg remained. The aqueous model, with the addition of <1 mM Cl(2) showed that this remaining Hg would be oxidized such that the final Hg(2)(2+) /Hg(2+) ratios matched the experimental data. Results of applying the model to DWPF show that due to excessive shortage of chloride, only 6% of the mercury fed is expected to be chlorinated, mostly as Hg(2)Cl(2), whereas the remaining mercury would exist either as elemental mercury (90%) or HgO (4%).

The Hanford LAW Vitrification facility, which will be part of the Hanford Waste Treatment Plant (WTP), has not yet been built but pilot scale melters have been operated with LAW simulants (non-radioactive 133Cs for radioactive 137Cs, non-radioactive 127I for radioactive 129I, and Re as surrogate for 99Tc) and the resulting off-gas condensate (recycle) analyzed. Recently Savannah River National Laboratory (SRNL) has successfully operated a Bench scale Steam Reformer (BSR) in the SRNL Shielded Cells Facility (SCF) with radioactive Savannah River Site (SRS) Tank 48 supernates. The BSR is a unique SRNL design and this radioactive capability does not exist commercially nor at any other DOE complex site. SRNL was contracted by THOR(TM) Treatment Technologies (TTT) to perform a BSR demonstration with both simulated and radioactive WTP Secondary Waste (WTP-SW). SRNL will mineralize recycle from the SRS Defense Waste Processing Facility (DWPF) that will be evaporated 20X and trimmed with radioactive 99Tc and mixtures of 137Cs and I or I to simulate the anticipated melter recycle from the LAW Vitrification facility in the WTP. During the BSR processing kaolin clay and coal fines will be added to the modified DWPF melter recycle waste to form the mineralized waste form at 6700C. The mineralized waste form will initially be made from a non-radioactive simulant. The product will be granular and will be characterized and tested using ASTM C1285, a static powdered waste form leach test in pure water, and the EPA TCLP for metals retention. Nonradioactive product will be made into monolith using a geopolymer binder, cured and compression tested. Monoliths will also be characterized and tested using ASTM C1285 and the EPA TCLP.

Wind turbines impact radar measurements as a result of their large reflectivity cross section as well as though the Doppler phase shift of their rotating blades. Wind farms can interfere with operational radar in multiple contexts, with degradation impacts on: weather detection such as tornado location, wind shear, and precipitation monitoring; tracking of airplanes where air traffic control software can lose the tracks of aircraft; and in identification of other low flying targets where a wind farm located close to a border might create a dead zone for detecting intruding objects. As a result, a number of potential wind power locations have been contested on the basis of radar line of site. Radar line of site is commonly assessed using a standard atmosphere assumption; however, it has been shown that the index of refraction and refractive gradient may depart substantially from these conditions, especially in critical weather conditions. Moreover, as wind energy development looks to offshore locations where super-refractive conditions are common, the development of site specific radar line of site determination is necessary to provide the optimal balance between future energy development and radar requirements. In order to help meet the recent goal established for increasing the capability for 20% wind energy by the year 2030 (US DOE 2008), a climatology of radar line of site is provided to investigate site dependent deviation from standard atmosphere assumptions. Based on the climatology, specific conditions leading to negative impacts can be determined. Operational determination of radar beam propagation effects for real-time assessment of mitigation strategies as well as assimilation and synthesis of Radar data will be provided. Many current mitigation strategies are based on post-processing software to remove artifacts and to employ anomalous propagation filtering and correction methods. Providing predictive propagation fields would allow radar systems as well as processing systems to adaptively apply mitigation strategies in a more efficient manner. In the extreme case where exclusion zones are employed, these periods could be determined in advance such that their automated use would be minimized. Novel methods which employ radar data themselves to detect atmospheric refractivity profiles will be discussed. There are currently a number of wind farms that are within line of site of existing NOAA Doppler weather radars. These wind farms are situated at a range of distances, and therefore will provide quantitative evaluation of impact forecasts. JF - American Meteorological Society. [np]. 16 Jun 2010.

A variety of bioassessment methods have been applied to aquatic ecosystems; however, terrestrial methods are less advanced. The objective of this study was to examine baseline differences in ant communities at different seral stages from clear cut to mature pine plantation as a precursor to developing a broader terrestrial bioassessment protocol. Comparative sampling was conducted at nine sites having four seral stages: clearcut, 5 year recovery, 15 year recovery, and mature stands. Soil and vegetation data were also collected at each site. Ants were identified to genus. Analysis of the ant data indicated that ants respond strongly to habitat changes that accompany ecological succession in managed pine forests, and both individual genera and ant community structure can be used as indicators of successional change. Ants exhibited relatively high diversity in both early and mature seral stages. High ant diversity in mature seral stages was likely related to conditions on the forest floor favoring litter dwelling and cold climate specialists. While ants may be very useful in identifying environmental stress in managed pine forests, adjustments must be made for seral stage when comparing impacted and unimpacted forests.

The average diameter and length of the nanorods are 80 nm and 200 nm, respectively. The aligned nanorods demonstrated high capacity of 1243 mAh g super(-1) at rate of 0.5 C. A gradual decrease of the initial capacity was observed. The characterization of the anodes shows that the changes of the crystalline structure and morphology during cycling may be responsible for the capacity decay. The appropriate selection of the substrate can overcome the problems and lead the sustainable high capacity.

The SDEs function is to produce hydrogen by using the Hybrid Sulfur (HyS) Process, a sulfur-based electrochemical/thermochemical hybrid cycle. Membrane stability was evaluated using a screening process where each candidate PEM was heated at 80 degree C in 60 wt% H sub(2)SO sub(4) for 24 h. Following acid exposure, chemical stability for each membrane was evaluated by FTIR using the ATR sampling technique. Membrane SO sub(2) transport was evaluated using a two-chamber permeation cell. SO sub(2) was introduced into one chamber whereupon SO sub(2) transported across the membrane into the other chamber and oxidized to H sub(2)SO sub(4) at an anode positioned immediately adjacent to the membrane. The resulting current was used to determine the SO sub(2) flux and SO sub(2) transport. Additionally, membrane electrode assemblies (MEAs) were prepared from candidate membranes to evaluate ionic conductivity and selectivity (ionic conductivity vs. SO sub(2) transport) which can serve as a tool for selecting membranes. MEAs were also performance tested in a HyS electrolyzer measuring current density vs. a constant cell voltage (1 V, 80 degree C in SO sub(2) saturated 30 wt% H sub(2)SO sub(4)). Finally, candidate membranes were evaluated considering all measured parameters including SO sub(2) flux, SO sub(2) transport, ionic conductivity, HyS electrolyzer performance, and membrane stability. Candidate membranes included both PFSA and non-PFSA polymers and polymer blends of which the non-PFSA polymers, BPVE-6F and PBI, showed the best selectivity.

Sediment Pu concentrations as a function of depth indicated that some Pu moved upward from the buried source material. Subsequent numerical modeling suggested that the upward movement was largely the result of invading grasses taking up the Pu and translocating it upward. The objective of this study was to determine if the Pu of surface sediments originated from atmosphere fallout or from the buried lysimeter source material (weapons-grade Pu), providing additional evidence that plants were involved in the upward migration of Pu. The super(240)Pu/ super(239)Pu and super(242)Pu/ super(239)Pu atomic fraction ratios of the lysimeter surface sediments, as determined by Thermal Ionization Mass Spectroscopy (TIMS), were 0.063 and 0.00045, respectively; consistent with the signatures of the weapons-grade Pu. Our numerical simulations indicate that because plants create a large water flux, small concentrations over multiple years may result in a measurable accumulation of Pu on the ground surface. These results may have implications on the conceptual model for calculating risk associated with long-term stewardship and monitored natural attenuation management of Pu contaminated subsurface and surface sediments.

a laboratory and modeling study AN - 742927819; 2010-057193 AB - Cellulosic materials, such as wood, paper products and cardboard that have been co-disposed with low-level nuclear waste have been shown to produce leachate with natural organic matter (NOM) concentrations of hundreds of mg/LC and, as such, have the potential to influence the fate and transport of radionuclides in the subsurface environment. The objective of this study was to examine the influence of NOM on the sorption of Eu (an analogue for trivalent radionuclides) to two coastal plain sediments from the US Department of Energy's Savannah River Site. Particular attention was directed at quantifying Eu interactions with NOM sorbed to sediments (NOM (sub sed) ) in laboratory experiments and developing conditional stability constants for that interaction using the thermodynamic equilibrium speciation model MINTEQA2. Europium sorption to the two sediments systematically increased as pH increased from 3.9 to 6.7. With increasing additions of NOM to the aqueous phase from 0 to 222 mg/LC, Eu sorption initially increased to a maximum at 10 mg/LC NOM (sub aq) and then decreased with increasing NOM (sub aq) concentrations. Increases in Eu sorption at low NOM additions was attributed to the sorption of NOM to the sediment surface increasing the number of sorption sites on the low cation-exchange capacity sediments and/or increasing the association constant (log K) for the Eu-sediment surface reaction. Decreases in Eu sorption at higher NOM levels was attributed to Eu (sub aq) complexation to NOM (sub aq) being more favored than Eu sorption to the solid phase. A component additivity model was developed to describe the Eu-NOM-sediment system by the additive effects of the three binary system models: Eu-NOM, Eu-sediment and NOM-sediment. The model generally captured the data trends in the ternary system. Conditional stability constants developed from the experimental data for the complexation of Eu to NOM (sub sed) were as much as four orders of magnitude greater than Eu complexation with NOM (sub aq) , presumably due to the NOM (sub sed) deriving additional negative (attractive) charge from the sediment surface. At high initial NOM (sub aq) levels, >99 mg/LC, the model captured the trend of reduced Eu sorption but tended to over-estimate Eu sorption. The additivity approach of combining binary models to form a ternary model was only successful when the unique complexation properties of the NOM (sub sed) were properly calculated.

Granular solids such as activated carbon, hematite, and sodium phosphates, if present as sludge components in nuclear waste storage tanks, have been found to be capable of precipitating/sorbing actinides like plutonium, neptunium, and uranium from nuclear waste storage tank supernatant liquor. Our results show that the removal of plutonium and neptunium from simulants by tank solid sludge components may be due to the presence of the activated carbon and metal oxides. Thus, the potential may exist for the accumulation of fissile materials in nuclear waste storage tanks containing trace levels of these radionuclides during lengthy nuclear waste storage and processing.

SRS streams are 'integrators' that potentially receive water transportable contaminants from all sources within their drainage basins, necessitating a watershed approach to organize contaminant distribution data and characterize the effects of multiple contaminants on aquatic organisms. This study used several lines-of-evidence to assess the ecological effects of metals in SRS streams, including contaminant exposure models for apex predators and bioassessments of fish and macroinvertebrate assemblages. Concentrations of metals in sediments, fish, and water were elevated in streams affected by SRS operations, but contaminant exposure models for the river otter Lontra Canadensis and belted kingfisher Ceryle alcyon indicated that toxicological reference values were exceeded only by Hg and Al. Macroinvertebrate assemblage structure was unrelated to sediment metal concentrations. Fish assemblage data were inconclusive. This study indicated that (1) modeling studies and field bioassessments provide a complementary basis for addressing the individual and cumulative effects of contaminants, (2) habitat effects must be controlled when assessing contaminant impacts, (3) sensitivity analyses of contaminant exposure models can help to apportion sampling effort, and (4) most individual metals in SRS streams are unlikely to have significant ecological effects.

Many of the wastes contain sulphate at concentrations that can be difficult to retain in borosilicate glass. Efforts to optimise the composition of a glass frit for combination with the waste to improve sulphate retention while meeting other process and product performance constraints are presented. The fabrication and characterisation of several series of simulated waste glasses are described. The experiments are detailed chronologically, to provide insight into part of the engineering studies used in developing frit compositions for an operating high-level waste vitrification facility. The results lead to the recommendation of a specific frit composition and a concentration limit for sulphate in the glass for the next batch of sludge to be processed at Savannah River.

Initial foam control studies with the Hanford tank waste showed that the antifoam agent reduced foaming. The antifoam agent was further tested using simulated Hanford tank waste spiked with an antifoam agent that was heated and irradiated (2.1t104rad/h) at conditions (90 degree C, 3M NaOH, 8h) expected in the processing of radioactive waste through the Waste Treatment and Immobilization Plant (WTP) at Hanford. After irradiation, the concentration of the major polymer components polydimethylsiloxane (PDMS) and polypropylene glycol (PPG) in the antifoam agent was determined by GPC. No significant loss of the major polymer components was observed after 24h and only 15wt% loss of PDMS was reported after 48h. The presence of degradation products were not observed by gas chromatography (GC), gas chromatography mass spectrometry (GCMS), or high performance liquid chromatography mass spectrometry (HPLC-MS). G values were calculated from the GPC analysis and tabulated. These analyses indicate that any loss of effectiveness of the antifoam agent within 24h of addition to the waste solution is not primarily due to chemical degradation but results from the separation and/or redistribution of the antifoam components from each other by physical means.

To treat waste streams that are high in 137Cs, 90Sr, and/or actinides, SRS developed the Actinide Removal Process (ARP) and the Modular Caustic Side Solvent Extraction (CSSX) Unit. Collectively, these two processes make up the Integrated Salt Disposition Process (ISDP). The ARP part is responsible for the removal of strontium and actinides, while the MCU part is responsible for removing cesium. This paper discusses the qualification testing of the second batch of caustic waste that is being processed through ISDP currently. This paper also describes the tests conducted and compares results with current facility performance. The ARP contacts the salt solution with monosodium titanate (MST) to sorb strontium and select actinides. After MST contact, the resulting slurry is filtered to remove the MST (and sorbed strontium and actinides) and entrained sludge. The filtrate is transferred to the MCU for further treatment to remove cesium. The solid particulates removed by the filter are concentrated to similar to 5wt%, washed to reduce the sodium concentration, and transferred to the Defense Waste Processing Facility (DWPF) for vitrification. The CSSX process extracts the cesium from the radioactive waste using a customized solvent to produce a Decontaminated Salt Solution (DSS), then strips and concentrates the cesium from the solvent with dilute nitric acid. The DSS is incorporated in grout while the strip acid solution is transferred to DWPF for vitrification. In order to predict waste behavior, the Savannah River National Laboratory (SRNL) personnel performed tests using actual radioactive samples of the second waste batch - Macrobatch 2 - for processing prior to the start of the operation. Testing included MST sorption to remove strontium and actinides followed by CSSX batch contact tests to verify expected cesium mass removal and concentration. This paper describes the tests conducted and compares results from MCU facility operations. The results include strontium, plutonium, and cesium removal, cesium concentration, and organic entrainment and recovery data. Our work indicates that the bench scale tests are a conservative predictor of actual waste performance.

In-tank ion exchange (IX) columns are being considered for cesium removal. The spherical form of resorcinol formaldehyde ion exchange resin (sRF) is being evaluated for decontamination of dissolved saltcake waste at SRS, which is generally lower in potassium and organic components than the Hanford waste. The sRF performance with SRS waste was evaluated in two phases: resin batch contacts and IX column testing with both simulated and actual dissolved salt waste. The tests, equipment, and results are discussed.

Observed final uranium concentrations ranged from 7mgU/L to 4.5gU/L. Final plutonium concentrations ranged from 4 mu gPu/L to 12mgPu/L. Actinide carbonate complexation is believed to result in the dramatic solubility increases observed for one sample over long time periods. Clarkeite, NaUO2(O)OH.H2O, was found to be the dominant uranium solid phase in equilibrium with the waste supernate in most cases.

The first step in preparing the tank for closure is mechanical sludge removal. In mechanical sludge removal, a liquid such as inhibited water or salt solution is added to the tank, the liquid is mixed with the sludge to form a slurry, and the slurry is transported from the tank. Mechanical cleaning removes a large fraction of the sludge in the tank, but it leaves a sludge heel of several thousand gallons. SRS employs chemical cleaning to remove this sludge heel. In chemical cleaning, oxalic acid is added to the tank to dissolve the sludge, and the liquid, containing the dissolved sludge, is transported from the tank. The authors conducted demonstrations of the chemical cleaning process with simulated SRS waste and actual SRS waste to assess the effectiveness of oxalic acid in dissolving SRS sludge. Following these demonstrations, SRS conducted chemical cleaning in two waste tanks (referred to as Tank A and Tank B). During chemical cleaning, the authors analyzed samples to assess the effectiveness of the chemical cleaning in removing the sludge heel. The conclusions from this work follow. With the exception of iron, the dissolution of sludge components from Tank A agreed with results from the actual waste demonstration performed in 2007. The fraction of iron removed from Tank A by chemical cleaning was significantly less than the fraction removed in the SRNL demonstrations. The likely cause of this difference is the high pH following the first oxalic acid strike. The dissolution of sludge components from Tank B agreed with results from the actual waste demonstration performed in 2007. The fraction of plutonium removed from Tank B by chemical cleaning was slightly higher than the fraction removed in the SRNL demonstrations. Most of the sludge mass remaining in the tank is iron and nickel. The remaining sludge contains significant amounts of barium, chromium, and mercury. Most of the radioactivity remaining in the residual material is beta emitters and 90Sr. The chemical cleaning removed a large fraction of the uranium, aluminum, calcium, sodium, strontium, and cesium. The chemical cleaning was not effective at removing nickel, mercury, plutonium, americium, and curium.

A statistically designed experiment was used to measure the solubility of Pu in simulated solutions with salt concentrations and temperatures which bounded those observed in SRS HLW solutions. Constituents of the simulated waste solutions included: hydroxide (OH-), aluminate {/ampp/image?path=/713708471/926439385/lsst_a_494090_o_ilm0001.gif } , sulfate {/ampp/image?path=/713708471/926439385/lsst_a_494090_o_ilm0002.gif } , carbonate {/ampp/image?path=/713708471/926439385/lsst_a_494090_o_ilm0003.gif } , nitrate {/ampp/image?path=/713708471/926439385/lsst_a_494090_o_ilm0004.gif } , and nitrite {/ampp/image?path=/713708471/926439385/lsst_a_494090_o_ilm0005.gif } anions. Each anion was added to the waste solution in the sodium form. The solubilities were measured at 25 and 80 degree C. Five sets of samples were analyzed over a six month period and a partial sample set was analyzed after nominally fifteen months of equilibration. No discernable time dependence of the measured Pu concentrations was observed except for two salt solutions equilibrated at 80 degree C which contained OH- concentrations >5mol/L. In these solutions, the Pu solubility increased with time. This observation was attributed to the air oxidation of a portion of the Pu from Pu(IV) to the more soluble Pu(V) or Pu(VI) valence states. A data driven approach was subsequently used to develop a modified response surface model for Pu solubility. Solubility data from this study and historical data from the literature were used to fit the model. The model predicted the Pu solubility of the solutions from this study within the 95% confidence interval for individual predictions and the analysis of variance indicated no statistically significant lack of fit. The Savannah River National Laboratory (SRNL) model was compared with predicted values from the Aqueous Electrolyte (AQ) model developed by OLI Systems, Inc. and a solubility prediction equation developed by Delegard and Gallagher for Hanford tank waste. The agreement between measured or values predicted by the SRNL model and values predicted by the OLI AG model was very poor. The much higher predicted concentrations by the OLI AQ model appears to be the result of the model predicting the predominate Pu oxidation state is Pu(V) which is reported as unstable below sodium hydroxide (NaOH) concentrations of 6M. There was very good agreement between the predicted Pu concentrations using the SRNL model and the model developed by Delegard and Gallagher with the exception of solutions that had very high OH- (15M) concentrations. The lower Pu solubilities in these solutions were attributed to the presence of {/ampp/image?path=/713708471/926439385/lsst_a_494090_o_ilm0006.gif } and {/ampp/image?path=/713708471/926439385/lsst_a_494090_o_ilm0007.gif } which limit the oxidation of Pu(IV) to Pu(V).

Researchers at the US DOE's Savannah River National Laboratory (SRNL) have developed a unique variation, called porous-wall hollow glass microspheres (PWHGMs), which offers the potential for use in targeted drug delivery, hydrogen storage and other applications. A network of interconnected pores in the thin outer shells of the microspheres ("microballoons") allows them to be filled with, hold, and release gases and other materials. SRNL is involved in different programmes involving PWHGMs, e.g. with Toyota to develop safe hydrogen gas storage systems, and with Mo-Sci Corp. to continue R&D of additional applications. The R&D work carried out at SRNL, a method developed by SRNL to fabricate PWHGMs by heating glass powders in a hot zone formed by a controlled gas-air flame, and the production of novel nano-filaments inside the microspheres are discussed.

It was found that this thermocouple measured the air temperature with root-mean-square errors of 0.35K within the Gill shield without correction. A linear temperature correction was evaluated based on the difference between the interior plate and thermocouple temperatures. This correction was found to be relatively insensitive to shield design and yielded an error of 0.16K for combined day and night observations. The correction was reliable in the daytime when the wind speed usually exceeds 1 m s super(-1) but occasionally performed poorly at night during very light winds. Inspection of the standard deviation in the thermocouple wire temperature identified these periods but did not unambiguously locate the most serious events. However, estimates of sensor accuracy during these periods is complicated by the much larger sampling volume of the mechanically-aspirated sensor compared with the naturally-aspirated sensor and the presence of significant near-surface temperature gradients. The root-mean-square errors therefore are upper limits to the aspiration error since they include intrinsic sensor differences and intermittent volume sampling differences.

Successful analysis of Se in high activity waste matrices is challenging for a variety of reasons. As a result of these unique challenges, the successful quantification of Se in the types of matrices present at SRS requires an extremely efficient and selective separation of Se from high levels of interfering radionuclides. A robust Se radiochemical separation method has been developed at the Savannah River National Laboratory (SRNL) which is routinely capable of successfully purifying Se from a wide range of interfering radioactive species. In addition to dramatic improvements in the Kd, ease, and reproducibility of the analysis, the laboratory time has been reduced from several days to only 6 h.

11059059 AB - Salt solution, from radioactive waste generated by the production of plutonium and tritium in nuclear reactors at the Savannah River Site, will be mixed with cement and flyash/slag to form a grout which will be poured into above ground concrete vaults. The curing process is exothermic, and a transient thermal model of the pouring and curing process is herein described. A peak temperature limit of 85 degree C for the curing grout restricts the rate at which it can be poured into a vault. The model is used to optimize the pouring.

CAP88 estimates radiation dose and the risk of health effects to human populations from radionuclide emissions to air. This program is used by several U.S. Department of Energy (DOE) facilities to comply with National Emission Standards for Hazardous Air Pollutants regulations. CAP88 Mainframe, referred to as version 1.0 on the U.S. Environmental Protection Agency Web site (http://www.epa.gov/radiation/assessment/CAP88/), was the very first CAP88 version released in 1988. Some DOE facilities including the Savannah River Site still employ this version (1.0) while others use the more user-friendly personal computer Windows-based version 3.0 released in December 2007. Version 1.0 uses the program RADRISK based on International Commission on Radiological Protection Publication 30 as its radionuclide database. Version 3.0 uses half-life, dose, and risk factor values based on Federal Guidance Report 13. Differences in these values could cause different results for the same input exposure data (same scenario), depending on which version of CAP88 is used. Consequently, the differences between the two versions are being assessed in detail at Savannah River National Laboratory. The version 1.0 and 3.0 database files contain 496 and 838 radionuclides, respectively, and though one would expect the newer version to include all the 496 radionuclides, 35 radionuclides are listed in version 1.0 that are not included in version 3.0. The majority of these has either extremely short or long half-lives or is no longer in production; however, some of the short-lived radionuclides might produce progeny of great interest at DOE sites. In addition, 122 radionuclides were found to have different half-lives in the two versions, with 21 over 3 percent different and 12 over 10 percent different.

Here we describe the incorporation of the FailSafe(TM) PCR System to optimize environmental analysis of dsr A by PCR amplification and denaturing gradient gel electrophoresis. PCR-DGGE analysis of dsr A composition revealed that SRB diversity was greater and more variable throughout the vertical profile of a marine sediment core obtained from a gas hydrate site (GC234) in the Gulf of Mexico than in a sediment core collected from a nearby site devoid of gas hydrates (NBP). Depth profiled dsr B abundance corresponded with sulfate reduction rates at both sites, though measurements were higher at GC234. This study exemplifies the numerical and functional importance of sulfate reducing bacteria in deep-sea sedimentary environments, and incremental methodological advancements, as described herein, will continue to streamline the analysis of sulfate reducer communities in situ.

The results of long-term Pu field lysimeter experiments at the Savannah River Site showed anomalous distributions below the source, with significant upward migration above the source. A previously developed reactive transport model with an initial application of a steady downward velocity successfully simulated the below-source distribution of the lysimeter data. Development and coupling of a transient flow model with root water uptake to the reactive transport model yielded a downward distribution fit almost identical to that from the steady-state flow application. The model predicted very little upward migration, however. Additional evaluations done by testing several soil hydraulic- and chemistry-related mechanisms that may enhance upward migration yielded no improvement. We developed an extension of the reactive transport model to include and test a new mechanism: root Pu uptake and xylem transport. The extended model produced simulations that capture the general behavior of the upward migration with no effect on the below-source fit. These results, with the support of the additional finding that elevated Pu concentrations in the lysimeter surface sediment originated from the source used in the experiments, indicated that Pu root uptake and transport is a valid explanation for the observed upward migration and may play an important role in near-surface Pu transport. Further research is needed to identify the uptake mechanisms and Pu behavior within plant systems, with special attention directed to the effect of Pu complexation with different chelating agents in soil and plants (siderophores, phytosiderophores, and others).

The composite was exposed to total gamma doses of 0.5, 1.0, and 2.0 MGy. Irradiated and baseline samples were tested for tensile strength, hardness and evaluated using Fourier transform infra-red spectroscopy and differential scanning calorimetry for structural changes. Scanning electron microscopy was used to evaluate microstructural behavior. Mechanical testing of the composite bars revealed no apparent change in modulus, strain to failure, or fracture strength after exposures. However, testing of only the epoxy matrix revealed changes in hardness, thermal properties, and spectroscopy results with increasing gamma irradiation. The results quantify the changes in the epoxy within the composite as a result of exposure to gamma radiation at doses relevant to service.

As iodine mobility varies greatly with iodine speciation, experiments with 129I-contaminated aquifer sediments from the Savannah River Site located in Aiken, SC, were carried out to test iodine interactions with soils and aquifer sediments. Using tracer 125I- and stable 127I- additions, it was shown that such interactions were highly dependent on I- concentrations added to sediment suspensions, contact time with the sediment, and organic carbon (OC) content, resulting in an empirical particle-water partition coefficient (Kd) that was an inverse power function of the added I- concentration. However, Kd values of organically bound 127I were 3 orders of magnitude higher than those determined after 1-2 weeks of tracer equilibration, approaching those of OC. Under ambient conditions, organo-iodine (OI) was a major fraction (67%) of the total iodine in the dissolved phase and by implication of the particulate phase. As the total concentration of amended I- increased, the fraction of detectable dissolved OI decreased. This trend, attributed to OC becoming the limiting factor in the aquifer sediment, explains why at elevated I- concentrations OI is often not detected.

This process uses a closed cycle of sodium and calcium hydroxide, carbonate, and oxide transformations to capture dilute CO sub(2) from the atmosphere and to generate a concentrated stream of CO sub(2) that is amenable to sequestration or subsequent chemical transformations. In one of the process steps, a fossil-fueled lime kiln is needed, which reduces the net CO sub(2) capture of the process. It is proposed to replace the fossil-fueled lime kiln with a modified kiln heated by a high-temperature nuclear reactor. This will have the effect of eliminating the use of fossil fuels for the process and increasing the net CO sub(2) capture. Although the process is suitable to support sequestration, the use of a nuclear power source for the process provides additional capabilities, and the captured CO sub(2) may be combined with nuclear-produced hydrogen to manufacture liquid fuels via Fischer-Tropsch synthesis or other technologies. Conceivably, such plants would be carbon-neutral and could be placed virtually anywhere without being tied to fossil fuel sources or geological sequestration sites.

9221167 AB - The feasibility of decontaminating spent fuel cladding hulls using hydrofluoric acid (HF) was investigated as part of the Global Energy Nuclear Partnership (GNEP) Separations Campaign. The concentrations of the fission product and transuranic (TRU) isotopes in the decontaminated hulls were compared to the limits for determining the low level waste (LLW) classification in the United States (US). The 90Sr and 137Cs concentrations met the disposal criteria for a Class C LLW; although, in a number of experiments the criteria for disposal as a Class B LLW were met. The TRU concentration in the hulls generally exceeded the Class C LLW limit by at least an order of magnitude. The concentration decreased sharply as the initial 30-40 mm of the cladding hull surface were removed. At depths beyond this point, the TRU activity remained relatively constant, well above the Class C limit.

Two sources of Pu were identified, the disposal basins, which contained a 240Pu/239Pu isotopic signature consistent with weapons grade Pu, and 244Cm, a cocontaminant that is a progenitor radionuclide of 240Pu. 240Pu that originated primarily from 244Cm tended to be appreciably more oxidized (Pu(V/VI)), less associated with colloids (1 kDa - 0.2 *mm), and more mobile than 239Pu, as suggested by our prior studies at this site. This is not evidence of isotope fractionation but rather 'source-dependent' controls on 240Pu speciation which are processes that are not at equilibrium, i.e., processes that appear kinetically hindered. There were also 'source-independent' controls on 239Pu speciation, which are those processes that follow thermodynamic equilibrium with their surroundings. For example, a groundwater pH increase in one well from 4.1 in 1998 to 6.1 in 2004 resulted in an order of magnitude decrease in groundwater 239Pu concentrations. Similarly, the fraction of 239Pu in the reduced Pu(III/IV) and colloidal forms increased systematically with decreases in redox condition in 2004 vs 1998. This research demonstrates the importance of source-dependent and source-independent controls on Pu speciation which would impact Pu mobility during changes in hydrological, chemical, or biological conditions on both seasonal and decadal time scales, and over short spatial scales. This implies more dynamic shifts in Pu speciation, colloids association, and transport in groundwater than commonly believed.

Results show that ion-exchange is an efficient method for cesium removal from highly alkaline radioactive waste solutions. On average, two 1300 liter columns operating in series are able to treat 690,000 liters of waste with an initial cesium concentration of 0.09 mM in 11 days achieving a decontamination factor of over 50,000. The study investigated the sensitivity of ion-exchange column performance to variations in flow, temperature, and column dimensions. Modeling results can be used to optimize the design of the ion exchange system.

Its consistent crush response, controllable structural properties and excellent thermal insulating characteristics have made it attractive as replacement for the widely used cane fibreboard for smaller, drum size packagings. Accordingly, polyurethane foam was chosen for the overpack material for the 9977 and 9978 packagings. The study reported here was undertaken to provide data to support the analyses performed as part of the development of the 9977 and 9978 packagings, and compared property values reported in the literature with published property values and test results for foam specimens taken from a prototype 9977 packaging. The study confirmed that, polyurethane foam behaves in a predictable and consistent manner and fully satisfies the functional requirements for impact absorption and thermal insulation.

The primary purpose of these impact limiters is to absorb energy to reduce loads on the cask structure during impacts associated with a severe accident. Impact limiters are also credited in many packages with protecting closure seals and reducing peak temperatures during fire events. For this credit to be taken in safety analyses, the impact limiter attachment system must be shown to retain the impact limiter following normal conditions of transport (NCT) and hypothetical accident conditions (HAC) impacts. Large casks are often certified by analysis only because of the cost associated with testing. Therefore, some cask impact limiter attachment systems have not been tested in real impacts. A recent structural analysis of the T-3 spent fuel containment cask found problems with the design of the impact limiter attachment system. Assumptions in the original safety analysis for packaging (SARP) concerning the loading in the attachment bolts were found to be inaccurate in certain drop orientations. This paper documents the lessons learned and their applicability to impact limiter attachment system designs.

This can create potentially high radon exposures. Consequently, studies to mitigate these exposures have been started. This study presents a preliminary investigation of radon in Tbilisi, the capital of Georgia. An independent radiological monitoring program in Georgia has been initiated by the Radiocarbon and Low-Level Counting Section of I. Javakhishvili Tbilisi State University with the cooperation of the Environmental Monitoring Laboratory of the Physics/ Health Physics Department at Idaho State University. At this initial stage the E-PERM systems and GammaTRACER were used for the measurement of gamma exposure and radon concentrations in air and water. Measurements in Sololaki, a densely populated historic district of Tbilisi, revealed indoor radon ( super(222)Rn) concentrations of 1.5-2.5 times more than the U.S. Environmental Protection Agency action level of 148 Bq m super(-3) (4 pCi L super(-1)). Moreover, radon-in-air concentrations of 440 Bq m super(-3) and 3,500 Bq m super(-3) were observed at surface borehole openings within the residential district Measurements of water from various tap water supplies displayed radon concentrations of 3-5 Bq L super(-1) while radon concentrations in water from the hydrogeological and thermal water boreholes were 5-19 Bq L super(-1). In addition, the background gamma absorbed dose rate in air ranged of 70-115 nGy h super(-1) at the radon test locations throughout the Tbilisi urban environment.

To that end, long-term experiments were conducted at the Savannah River Site, where a series of lysimeters containing sources of reduced plutonium (Pu) were placed in the shallow subsurface (21 cm depth) and exposed to the environment for approximately 11 years. After the experiments, Pu activity concentrations were measured along vertical cores from the lysimeters. Results showed anomalous activity distributions below the source, with migration of Pu above the source all the way to the soil surface. Based on previous laboratory experiments, a fully-transient flow and reactive transport model with surface-mediated redox reactions was developed to simulate water flow due to rainfall/transpiration and the resulting Pu transport due to advection, dispersion and adsorption. This model was able to explain the downward migration of Pu, but not the upward migration. Through a process of elimination it was concluded that upward migration must occur through Pu absorption by grass roots and upward movement in the transpiration stream. Therefore, the reactive transport model was extended to include solution uptake by roots and Pu transport through the root/stem xylem. The extended model produced simulations that capture the general behavior of the upward migration with no effect on the below-source fit. These results, with the support of additional isotope ratio measurements showing that Pu on the surface of the lysimeter was from the source used in the experiments, not atmospheric fallout, indicated that Pu root uptake and xylem transport is a valid explanation for observed upward migration and may play an important role in near-surface Pu transport. Inferred xylem cross-sections and required head drops are reasonable. Further research is needed to identify the uptake mechanisms and detailed Pu behavior within plant systems.

Batch experiments were conducted to identify amendments and mixtures of amendments for metal and organic contaminant removal and retention. Contaminant removal was evaluated by calculating partitioning coefficients. Metal retention was evaluated by desorption studies in which residue from the removal studies was extracted with 1 M MgCl2 solution. The results indicated that phosphate amendments, some organoclays, and the biopolymer, chitosan, were very effective sequestering agents for metals in fresh and salt water. Organoclays were very effective sorbents for phenanthrene, pyrene, and benzo(a)pyrene. Partitioning coefficients for the organoclays were 3000-3500 L g-1 for benzo(a)pyrene, 400-450 L g-1 for pyrene, and 50-70 L g-1 for phenanthrene. Remediation of sites with a mixture of contaminants is more difficult than sites with a single contaminant because metals and organic contaminants have different fate and transport mechanisms in sediment and water. Mixtures of amendments (e.g., organoclay and rock phosphate) have high potential for remediating both organic and inorganic contaminants under a broad range of environmental conditions, and have promise as components in active caps for sediment remediation.

This glass was buried in a lysimeter in the SRS burial ground for 24 years. Lysimeter leachate data was available for the first 8 years. The glass was exhumed in 2004. The glass was predicted to be very durable and laboratory tests confirmed this. Scanning electron microscopy of the glass burial surface showed no significant glass alteration consistent with results of other laboratory and field tests. Radionuclide profiling for alpha, beta, and 137Cs indicated that Pu was not enriched in the soil while 137Cs and 90Sr were enriched in the first few centimeters surrounding the glass.

To that end, long-term experiments were conducted at the Savannah River Site in South Carolina, where a series of lysimeters containing sources of plutonium (Pu) in different oxidation states was placed in the shallow subsurface and exposed to the environment for 2 to 11 yr. Then, sediment Pu activity concentrations were measured along vertical cores taken from the lysimeters. Results showed anomalous activity distributions below the source, with significant migration of Pu above the source. A previously developed reactive transport model with surface-mediated redox reactions successfully simulated the lysimeter results below the source, assuming a steady, net downward flow. To simulate more realistic field conditions, a transient variably saturated flow model with root water uptake is developed and coupled to the reactive transport model. Overall, the fully transient analysis shows results nearly identical to the much simpler steady flow analysis. Thus, the surface-mediated redox hypothesis remains consistent with the below-source experimental data, the most important variable affecting transport being the oxidation state of the source material. However, none of the models studied could produce the upward Pu transport observed in the data. The hydraulic and chemical mechanisms tested as potential causes for upward migration--a modified root distribution, hysteresis, and air-content dependent oxidation--yielded little or no enhancement of the upward Pu movement. This suggests another transport mechanism such as root Pu uptake and translocation in the transpiration stream.

Development of such models requires accurate bathymetry, coastline, and boundary condition data in conjunction with the ability to rapidly discretize model domains and interpolate the required geospatial data onto the domain. To facilitate rapid and accurate hydrodynamic model development, SRNL has developed a pre- and post-processor application in a geospatial framework to automate the creation of models using existing data. This automated capability allows development of very detailed models to maximize exploitation of available surface water radionuclide sample data and thermal imagery.

AN - 70502741; 18374392 AB - The use of sequestering agents for the transformation of radionuclides in low concentrations in contaminated soils/sediments offers considerable potential for environmental cleanup. This study evaluated the influence of three types of phosphate (rock phosphate, biological phosphate, and calcium phytate) and two microbial amendments (Alcaligenes piechaudii and Pseudomonas putida) on U mobility. All tested phosphate amendments reduced aqueous U concentrations more than 90%, likely due to formation of insoluble phosphate precipitates. The addition of A. piechaudii and P. putida alone were found to reduce U concentrations 63% and 31%, respectively. Uranium removal in phosphate treatments was significantly reduced in the presence of the two microbes. Two sediments were evaluated in experiments on the effects of phosphate amendments on U mobility, one from a stream on the Department of Energy's Savannah River Site near Aiken, SC and the other from the Hanford Site, a Department of Energy facility in Washington state. Increased microbial activity in the treated sediment led to a reduction in phosphate effectiveness. The average U concentration in 1 M MgCl(2) extract from U contaminated sediment was 437 microg/kg, but in the same sediment without microbes (autoclaved), the extractable U concentration was only 103 microg/kg. The U concentration in the 1 M MgCl(2) extract was approximately 0 microg/kg in autoclaved amended sediment treated with autoclaved biological apatite. These results suggest that microbes may reduce phosphate amendment remedial effectiveness.

AN - 69182224; 18222573 AB - Microbial melanin production by autochthonous bacteria was explored in this study as a means to increase U immobilization in U contaminated soil. This article demonstrates the application of bacterial physiology and soil ecology for enhanced U immobilization in order to develop an in situ, U bio-immobilization technology. We have demonstrated microbial production of a metal chelating biopolymer, pyomelanin, in U contaminated soil from the Tims Branch area of the Department of Energy (DOE), Savannah River Site (SRS), South Carolina, as a result of tyrosine amendments. Bacterial densities of pyomelanin producers were >10(6) cells per g wet soil. Pyomelanin demonstrated U complexing and mineral binding capacities at pH 4 and 7. In laboratory studies, in the presence of goethite or illite, pyomelanin enhanced U sequestration by these minerals. Tyrosine amended soils in a field test demonstrated increased U sequestration capacity following pyomelanin production up to 13 months after tyrosine treatments.

AN - 69179572; 18191312 AB - During the last 50 years, a large amount of information on radionuclide accumulators or "sentinel-type" organisms in the environment has been published. Much of this work focused on the risks of food-chain transfer of radionuclides to higher organisms such as reindeer and man. Until the 1980s and 1990s, there were few published data on the radiocesium ((134)Cs and (137)Cs) accumulation by mushrooms. The present review of published data for (134,137)Cs accumulation by mushrooms in nature discusses the aspects that promote (134,137)Cs uptake by mushrooms and focuses on mushrooms that demonstrate a propensity for use in the environmental biomonitoring of radiocesium contamination. Transfer factors (TF, as dry weight concentration in fruiting body divided by concentration in substrate) ranged up to 24 (unitless), and aggregate transfer factors (T(ag), as Bq(137)Cs/kg dw in fruiting body divided by the aerial deposition as Bq/m(2)) ranged up to 8m(2)/kg dw.

AN - 70486773; 18403957 AB - A graded approach to flow and transport modeling has been used as a cost effective solution to evaluating potential groundwater risk in support of Deactivation and Decommissioning activities at the United States Department of Energy's Savannah River Site (SRS) in Aiken, South Carolina. This approach balances modeling complexity with potential risk and has been successfully used at SRS to reduce costs and accelerate schedule without compromising human health or the environment. The approach incorporates both simple spreadsheet calculations (i.e., screening models) and complex numerical modeling to evaluate the threat to human health posed by contaminants leaching from decommissioned concrete building slabs. Simple spreadsheet calculations were used to produce generic slab concentration limits for a suite of radiological and non-radiological contaminants for a chemical separations area at SRS. These limits, which are based upon the United States Environmental Protection Agency Soil Screening Guidance, were used to eliminate most building slabs from further risk assessment, thereby limiting the time and associated cost of the more rigorous assessment to higher risk facilities. Of the more than 58 facilities located in the area, to date only one slab has been found to have a contaminant concentration in excess of the area specific slab limit. For this slab, a more rigorous numerical modeling effort was undertaken which eliminated some of the simplifying and conservative assumptions inherent in the spreadsheet calculations. Results from the more sophisticated numerical model show that the remaining contaminant of concern would not likely impact groundwater above drinking water standards.

AN - 69654361; 17899247 AB - The spatial pattern of antibiotic resistance in culturable sediment bacteria from four freshwater streams was examined. Previous research suggests that the prevalence of antibiotic resistance may increase in populations via indirect or coselection from heavy metal contamination. Sample bacteria from each stream were grown in media containing one of four antibiotics-tetracycline, chloramphenicol, kanamycin, and streptomycin-at concentrations greater than the minimum inhibitory concentration, plus a control. Bacteria showed high susceptibilities to the former two antibiotics. We summarized the latter two more prevalent (aminoglycoside) resistance responses and ten metals concentrations per sediment sample, by Principal Components Analysis. Respectively, 63 and 58% of the variability was explained in the first principal component of each variable set. We used these multivariate summary metrics [i.e., first principal component (PC) scores] as input measures for exploring the spatial correlation between antibiotic resistance and metal concentration for each stream sampled. Results show a significant and negative correlation between metals PC scores versus aminoglycoside resistance scores and suggest that selection for metal tolerance among sediment bacteria may influence selection for antibiotic resistance differently in sediments than in the water column. Our most important finding comes from geostatistical cross-variogram analysis, which shows that increasing metal concentration scores are spatially associated with decreasing aminoglycoside resistance scores--a negative correlation, but holds for contaminated streams only. We suspect our field results are influenced by metal bioavailability in the sediments and by a contaminant promoted interaction or "cocktail effect" from complex combinations of pollution mediated selection agents.

S. DOE Savannah River Site AN - 1438971953; 2013-076246 AB - The composition of chlorinated hydrocarbon DNAPLs (dense non-aqueous phase liquids) from field sites can be substantially different than the material originally purchased for use as a solvent. Waste management practices at the U.S. Department of Energy's (DOE) Savannah River Site (SRS) included co-disposal of a wide range of organic and inorganic wastes. In 1991, a clear, orange-colored DNAPL was found in two wells near the SRS M-area settling basin. Waste effluent from the fuel and target fabrication facilities that were discharged to this settling basin included acids, caustics, metals and chlorinated solvents. The characterization of the SRS DNAPL suggests that numerous constituents partitioned into the DNAPL during its use as a solvent, co-disposal and ultimate migration through the subsurface. Trace constituents in the DNAPL include metals, from processing operations or co-disposal practices and subsurface minerals, high molecular weight hydrocarbons and alkyl esters, and acids. This complex mixture results in DNAPL-water interfacial properties that are substantially different than would be expected from a simple mixture of PCE and TCE. Under conditions when there is a high DNAPL to water volume ratio, a semi-rigid film accumulates on water droplets suspended in the DNAPL. It is concluded that the array of precipitated metal species comprising this film contributes to the interfacial tension that is over an order of magnitude lower than expected for a "clean" PCE/TCE mixture.

Routine monitoring indicated that copper concentrations were regularly higher than discharge permit limit, and water routinely failed toxicity tests. These conditions necessitated treatment of nearly 1 million gal of water/day (3.78 million L of water/day) plus storm runoff. Washington Savannah River Company personnel explored options to bring process and runoff waters into compliance with the permit conditions, including source reduction, engineering solutions, and biological solutions. A conceptual design for a constructed wetland treatment system was developed, and the full-scale system was constructed and began operation in 2000. The overall objective of our research was to better understand the mechanisms of operation of the A-01 wetland treatment system to provide better input to the design of future systems. The system is a vegetated surface flow wetland with a hydraulic retention time of approximately 48 hr. Copper, mercury, and lead removal efficiencies are very high, all in excess of 80% removal from water passing through the wetland system. Zinc removal is 60%, and nickel is generally unaffected. Dissolved organic carbon in the water column is increased by the system and reduces the toxicity of the effluent. Concentrations of metals in the A-01 wetland treatment system sediments generally decrease with depth and along the flow path through the wetland. Sequential extraction results indicate that most metals are tightly bound to wetland sediments.

One experimental method for the isolation of HE residue involves using solid phase microextraction (SPME) fibers to remove residue of interest. Due to their high affinity for organics, SPME fibers should have little affinity for most metals. However, no studies have measured the affinity of radionuclides for SPME fibers. The focus of this research was to examine the affinity of dissolved radionuclide ( super(239/240)Pu, super(238)U, super(237)Np, super(85)Sr, super(133)Ba, super(137)Cs, super(60)Co and super(226)Ra) and stable radionuclide surrogate metals (Sr, Co, Ir, Re, Ni, Ba, Cs, Nb, Ru, and Nd) for SPME fibers at the exposure conditions that favor the uptake of HE residues. Our results from radiochemical and mass spectrometric analyses indicate these metals have little measurable affinity for these SPME fibers during conditions that are conducive to HE residue uptake with subsequent analysis by liquid or gas phase chromatography with mass spectrometric detection.

The purpose of this study was to explore a possible linkage between the uptake of transition metals and extreme resistance to ionizing radiation and oxidative stress. The effects of six different divalent cationic metals on growth were examined in the absence of ionizing radiation. None of the metals tested were stimulatory, though cobalt was inhibitory to growth. In contrast, copper supplementation dramatically increased colony formation during chronic irradiation. K. radiotolerans exhibited specific uptake and intracellular accumulation of copper, compared to only a weak response to both iron and manganese supplementation. Copper accumulation sensitized cells to hydrogen peroxide. Acute-irradiation-induced DNA damage levels were similar in the copper-loaded culture and the age-synchronized no-copper control culture, though low-molecular-weight DNA was more persistent during postirradiation recovery in the Cu-loaded culture. Still, the estimated times for genome restoration differed by only 2 h between treatments. While we cannot discount the possibility that copper fulfills an unexpectedly important biochemical role in a low-radioactivity environment, K. radiotolerans has a high capacity for intracellular copper sequestration and presumably efficiently coordinated oxidative stress defenses and detoxification systems, which confers cross-protection from the damaging effects of ionizing radiation.

Noncompliant items are removed before the drums undergo further characterization in preparation for shipment to the Waste Isolation Pilot Plant (WIPP). Maintaining the flow of drums through the remediation process is critical to the program's seven-days-per-week operation. Conservative assumptions are used to ensure that glovebox contamination from this continual operation is below acceptable limits. Holdup measurements using cooled HPGe spectrometers are performed in order to confirm that these assumptions are conservative. super(239)Pu is the main nuclide of interest; however, super(241)Pu, equilibrium super(237)Np/ super(233)Pa and super(238)Pu (if detected) are typically assayed. At the Savannah River National Laboratory (SRNL) facility super(243,244,245)Cm are also generally observed and are always reported at either finite levels or at limits of detection. A complete assay at each of the three facilities includes a measure of TRU content in the gloveboxes and HEPA filters in the glovebox exhaust. This paper includes a description of the gamma -PHA acquisitions, of the modeling, and of the calculations of nuclide content. Because each of the remediation facilities is unique and ergonomically unfavorable to gamma -ray acquisitions, we have constructed custom detector support devices specific to each set of acquisitions. This paper includes a description and photographs of these custom devices. The description of modeling and calculations include determination and application of container and matrix photon energy dependent absorption factors and also determination and application of geometry factors relative to our detector calibration geometry. The paper also includes a discussion of our measurements' accuracy using off-line assays of two SRNL HEPA filters. The comparison includes assay of the filters inside of 55-gallon drums using the SRNL Q super(2) assay system and separately using off-line assay with an acquisition configuration unique from the original in-situ acquisitions.

Exclusion of conservative tracers and a decrease in U sorption compared with what was predicted by the mass-averaged equilibrium distribution coefficient (K (sub d-mass-avg) ) was observed in sediment mixtures where the mass fraction of silt loam was 10%. This is consistent with behavior that was previously reported for coarse and fine sand separates. No exclusion of the conservative tracer, as predicted for the moderate water content range, was measured during unsaturated transport in sediment mixtures that contained 30% or more silt loam by mass. Sorption under unsaturated conditions was greater than predicted based on the batch sorption measurement of K (sub d-mass-avg) value, however, which suggests that the fine-textured silt was in contact with the mobile water domain. This is the first evidence linking sorption to transport in a particular water domain. Results of this investigation demonstrate that the interaction between the geochemical and hydrodynamic processes has a profound effect on transport in unsaturated sediments. Definition of the fraction of mobile water was especially important for defining the front of the breakthrough curve, which is integral to predicting the arrival time of solutes at a particular depth and location in the sediment.

Sampling was weekly from February through July in 1983, 1984 and 1985. Ichthyoplankton transport was used as an estimate of ichthyoplankton production. Ichthyoplankton transport in the river, for both total and most common taxa, was highest in 1983 and lowest in 1985. Ichthyoplankton transport into the river from tributary streams was also highest in 1983 and lowest in 1985. Ichthyoplankton transported from these tributaries sometimes comprised a significant percent of the larval transport at the next river station downstream from the tributary mouth. The highest larval transport occurred when the spring flood pulse was most elevated for the longest time, and larval transport at particular river stations or creeks was correlated with floodplain width in 1983 and 1984, years when flood pulses were high enough so that the adjacent floodplain was inundated during or following spawning. In 1985 the flood pulse was brief, inundation levels were low, and inundation occurred in February before most fish had spawned. Except for American shad and sunfishes, larval transport for all common taxa was greatly reduced in 1985 compared to 1983.

The final objective of the study is improved dual-domain transport modeling predictions using multi-scale facies-based characterization parameters. Data collected to date has delineated facies through multi-scale field characterization data (cone penetration testing (CPT), rotosonic coring, gamma logs, water and soil headspace analysis, electromagnetic borehole flowmeter (EBF), slug tests, injection tests, and water level data). Surface and shallow geophysical techniques will be integrated with the overall facies framework for transport modeling. The study area is located in the upper Atlantic coastal plain of South Carolina consisting of interbedded and heterogeneous fluvial, deltaic, and shallow-marine sediments. The area also has a trichloroethylene (TCE) plume, with concentrations ranging from less than 100 ug/L to greater than 20,000 ug/L. Geophysical and hydrogeologic borehole-scale data were collected and analyzed from three new wells, piezometer installation and CPT. Three clay-rich horizons and three sand-rich horizons along with a very poorly sorted pebble-rich zone were defined. Hydrofacies were assigned using core-descriptions, sieve data, and EBF data. Water and soil headspace analysis provided contaminant concentrations. Lower concentrations of TCE were observed in the high permeability (K) facies and low K facies while higher concentrations appear in the moderate K facies and fringes of low K intervals. The data support a hydrofacies framework for transport modeling and suggest the plume center of mass has since passed the study area. Additional characterization data will be collected to refine the integrated hydrogeophysical model for the dual-domain TCE transport model based on the findings to date.

AN - 69869983; 19057647 AB - Kineococcus radiotolerans SRS30216 was isolated from a high-level radioactive environment at the Savannah River Site (SRS) and exhibits gamma-radiation resistance approaching that of Deinococcus radiodurans. The genome was sequenced by the U.S. Department of Energy's Joint Genome Institute which suggested the existence of three replicons, a 4.76 Mb linear chromosome, a 0.18 Mb linear plasmid, and a 12.92 Kb circular plasmid. Southern hybridization confirmed that the chromosome is linear. The K. radiotolerans genome sequence was examined to learn about the physiology of the organism with regard to ionizing radiation resistance, the potential for bioremediation of nuclear waste, and the dimorphic life cycle. K. radiotolerans may have a unique genetic toolbox for radiation protection as it lacks many of the genes known to confer radiation resistance in D. radiodurans. Additionally, genes involved in the detoxification of reactive oxygen species and the excision repair pathway are overrepresented. K. radiotolerans appears to lack degradation pathways for pervasive soil and groundwater pollutants. However, it can respire on two organic acids found in SRS high-level nuclear waste, formate and oxalate, which promote the survival of cells during prolonged periods of starvation. The dimorphic life cycle involves the production of motile zoospores. The flagellar biosynthesis genes are located on a motility island, though its regulation could not be fully discerned. These results highlight the remarkable ability of K radiotolerans to withstand environmental extremes and suggest that in situ bioremediation of organic complexants from high level radioactive waste may be feasible.

Activity concentrations in soil and vegetation were higher near the center of the floodplain than near the edges as a result of frequent inundation coupled with the presence of low areas that trapped contaminated sediments. super(137)Cs activity was highest near the soil surface, but depth related differences diminished with time as a likely result of downward diffusion or leaching. Activity concentrations in vegetation were significantly related to concentrations in soil. The plant to soil concentration ratio (dry weight) averaged 0.49 and exhibited a slight but significant tendency to decrease with time. The effective half-lives for super(137)Cs in shallow (0-7.6 cm) soil and in vegetation were 14.9 (95% CI = 12.5-17.3) years and 11.6 (95% CI = 9.1-14.1) years, respectively, and rates of super(137)Cs removal from shallow soil and vegetation did not differ significantly among sampling locations. Potential health risks on the Creek Plantation floodplain have declined more rapidly than expected on the basis of radioactive decay alone because of the relatively short effective half-life of super(137)Cs.

AN - 20689617; 10243491 AB - The seminal milestones in the development of attenuation based remedial strategies for chlorinated solvents were the U. S. Environmental Protection Agency (EPA) Technical protocol for evaluating natural attenuation of chlorinated solvents in ground water, and the subsequent EPA directive on the use of monitored natural attenuation (MNA). These protocols and guidelines lay out the concept of using multiple lines of evidence to document the viability of a MNA remedy, the monitoring needed to track performance, and important related criteria such as risk and contingencies. Success of the current protocols and directive has compellingly demonstrated that natural attenuation based actions are logical and viable at appropriate sites. MNA remedies move toward remediation goals at an acceptable rate and limit the collateral damages sometimes associated with active remedies (e.g., physical/chemical ecosystem disruption, energy use, etc.). Recently, the U. S. Department of Energy (DOE) and the Interstate Technology and Regulatory Council (ITRC) completed a three year project that assessed the state of practice for attenuation based remedies for chlorinated organics, evaluated emerging science, and developed technical guidance and recommendations to encourage appropriate-beneficial uses of natural attenuation processes as part of an overall process to clean up sites and achieve remedial objectives. The team emphasized the concepts of plume stability, low risk, sustainability, and progress toward achieving remediation goals. In a practical sense, this has led to three major lines of inquiry: 1) developing a mass balance approach to attenuation remedies, 2) examining sustainable enhancements of attenuation, and 3) exploring innovative characterization and monitoring. The key product areas produced by the effort include: Historical assessment of MNA practice: Where it has been used? What key data were used to document the process? What models were used to support permitting? What is the status and success to date? Technical and Regulatory Guidance: An ITRC effort to document the framework for integrating attenuation into the remediation strategy for contaminated sites and to provide tools to answer common questions - How much source removal is needed? When can a pump-and-treat system be responsibly turned off? What is the role of attenuation at chlorinated organic sites that do not have anaerobic condition? Can commercial (or new) remediation technologies be used to sustainably enhance attenuation processes? Modeling and analysis tools and monitoring methods to support regulators and environmental professionals as they implement MNA or enhanced attenuation (EA).

Most proposed ways to avoid the potentially large temperature increases (and their costlyeffects) are aimed at minimizing future carbon dioxide concentrations, keeping them at or near current levels (oreven reducing them). An alternative to these plans is to actively regulate the amount of solar radiation hitting the surface.Various proposals have been put forth to do this, but our research focuses on the introduction of porous glassmicrospheres into the stratosphere, where they will be expected to persist for long periods. Unlike similar plansto release sulfate aerosol into the stratosphere, the use of a manufactured aerosol allows us to prescribe theaerosol size and other properties. We have performed theoretical calculations to determine the mass of glass aerosol needed to makesignificant reductions in the surface shortwave flux, and we have used a global climate model to simulate theeffect of placing these microspheres in the stratosphere. The consequent changes in the Earth's radiativebalance and the effects on global climate are used as measures to evaluate the scheme.

Experiments were performed to determine the corrosion rate of lead when exposed to offgas or degradation products of these organic materials. The results showed that the room temperature vulcanising sealant was the most corrosive organic species used in the construction of the packaging, followed by polyvinyl acetate glue. Fibreboard material, also used in the construction of the packaging induced corrosion to a much lesser extent than the polyvinyl acetate glue and room temperature vulcanising sealant, and only in the presence of condensed water. The results indicated faster corrosion at temperatures higher than ambient and with condensed water. In light of these corrosion mechanisms, the lead shielding was sheathed in a stainless steel liner to mitigate corrosion.

Five nuclear reactors at the SRS produced special nuclear materials for the nation's defense program throughout the cold war era. An important step in the process was thorough degreasing of the fuel and target assemblies prior to irradiation. Discharges from this degreasing process resulted in significant groundwater contamination that would continue well into the future unless a soil remediation action was performed. The largest reactor contamination plume originated from C-Reactor and an interim action was selected in 2004 to remove the residual trichloroethylene (TCE) source material by electrical resistance heating (ERH) technology. This would be followed by monitoring to determine the rate of decrease in concentration in the contaminant plume. Because of the existence of numerous chlorinated solvent sources around SRS, it was elected to generate in-house expertise in the design and operation of ERH, together with the construction of a portable ERH/SVE system that could be deployed at multiple locations around the site. This paper describes the waste unit characteristics, the ERH system design and operation, together with extensive data accumulated from the first deployment adjacent to the C-Reactor building. The installation heated the vadose zone down to 62 feet bgs over a 60 day period during the summer of 2006 and raised soil temperatures to over 200 degrees F. A total of 730 lbs of trichloroethylene (TCE) were removed over this period, and subsequent sampling indicated a removal efficiency of 99.4%.

Unlike the native sediments, illite has inherent characteristics that increase its propensity to sorb super(137)Cs in a nearly irreversible manner. The objectives of this study were to determine if the addition of illite to super(137)Cs-contaminated, native sediments would effectively reduce plant uptake of super(137)Cs, and to establish the illite concentration most effective in achieving that result. Two plant species, corn and soybean, were grown in native sediments amended with illite at concentrations ranging from 0 to 5%. The illite amendment effectively decreased plant uptake of super(137)Cs, as concentration ratios (CR; Cs sub(plant)/Cs sub(soil)) for both plants decreased with increasing illite concentration. The 5%-illite treatment induced corn CRs to decrease by 29% and soybean CRs to decrease by 42%. The greatest incremental benefit was observed with an illite amendment of approximately 0.5%.

This configuration consists of a high-level waste (HLW) canister fitted with a rack that holds mini-canisters containing a Pu-bearing lanthanide borosilicate (LaBS) waste glass and/or titanate-based ceramic ( approximately 15% of the total canister volume). The remaining volume of the HLW canister is then filled with HLW glass ( approximately 85% of the total canister volume). A 6-a pressurized unsaturated flow (PUF) test was conducted to investigate waste form-waste form interactions that may occur when water penetrates the canisters and contacts the waste forms. The PUF column volumetric water content was observed to increase steadily during the test because of water accumulation associated with alteration phases formed on the surfaces of the glasses. Periodic excursions in effluent pH, electrical conductivity, and solution chemistry were monitored and correlated with the formation of a clay phase(s) during the test. Geochemical modeling, with the EQ3NR code, of select effluent solution samples suggests the dominant secondary reaction product for the surrogate HLW glass, SRL-202, is a smectite di-octahedral clay phase(s), possibly nontronite [Na (sub 0.33) Fe (sub 2) (AlSi) (sub 4) O (sub 10) (OH) (sub 2) .n(H (sub 2) O)] or beidellite [Na (sub 0.33) Al (sub 2.33) Si (sub 3.67) O (sub 10) (OH) (sub 2) ]. This clay phase was identified in scanning electron microscope (SEM) images as discrete spherical particles growing out of a hydrated gel layer on reacted SRL-202 glass. Alpha energy analysis (AEA) of aliquots of select effluent samples that were filtered through a 1.8nm filter suggest that approximately 80% of the total measurable Pu was in the form of a filterable particulate, in comparison to unfiltered aliquots of the same sample. These results suggest the filterable particles are >1.8nm but smaller than the 0.2mu m average diameter openings of the Ti porous plate situated at the base of the column. In this advection-dominated system, Pu appeared to be migrating principally as or in association with colloids after being released from the LaBS glass. Analyses of reacted LaBS glass particles with SEM with energy dispersive X-ray spectroscopy suggest that Pu may have segregated into a discrete disk-like phase, possibly PuO (sub 2) . Alteration products that contain the neutron absorber Gd have not been positively identified. Separation of the Pu and the neutron absorber Gd during glass dissolution and transport could be a criticality issue for the proposed repository. However, the translation and interpretation of these long-term PUF test results to actual disposed waste packages requires further analysis.

Mercury levels were highest in 1971 but declined over the next 10 years due to the mitigation of point source industrial pollution. Mercury levels in fish began to increase in the 1980s as a likely consequence of mercury inputs from tributaries and associated wetlands where mercury concentrations were significantly elevated in water and fish. Mercury levels in Savannah River fish decreased sharply in 2001-2003 coincident with a severe drought in the Savannah River basin, but returned to previous levels in 2004 with the resumption of normal precipitation. Regression models showed that mercury levels in fish changed significantly over time and were affected by river discharge. Mercury levels in Savannah River fish were only slightly lower in 2004 (0.3 to 0.8 mg/kg) than in 1971 (0.4 to 1.0 mg/kg) despite temporal changes during the intervening years.

The impact of colloid generation on formation permeability at injection rates ranging from 19 to 132 L min (super -1) was monitored using a set of six sampling wells radially spaced at approximate distances of 2.0, 3.0, and 4.5 m from a central injection well. Each sampling well was further divided into three discrete sampling depths that were pumped continuously at a rate of approximately 0.1 L min (super -1) throughout the course of the injection experiment. Discrete samples were collected for turbidity and chemical analysis. Turbidity varied greatly between sampling wells and zones within a given well, ranging from 1 mu m) to be readily mobile within the formation. Turbidity measurements taken during this study indicate that colloid mobilization induced by water injection was both spatially and temporally heterogeneous. Furthermore, colloid release did not follow simple predictions based on shear force, presumably due to the complexities encountered in real heterogeneous systems. These findings have important implications to our understanding of how colloids and the co-contaminants are mobilized in the subsurface environment, as well as for the development of monitoring practices that minimize the creation of colloidal artifacts. Technical and logistical obstacles encountered in conducting such an extensive field experiment are also discussed.

The SVE system has been operating since September 1999 and numerous tests have been performed on the system. A model was developed to simulate SVE at this site, incorporating the effects of contaminant behavior in a layered subsurface as well as the effects of contaminant diffusion into and out of soil aggregates. The objectives of this study were to: (i) compare the field data from the site with predictions from this mechanistic model; and (ii) establish the case for closure based on field observations and model predictions. A dense non-aqueous-phase liquid TCE source was discovered at the site during the course of operation. Location of this source compares well with the predicted residual source from the application of the diffusion components of the SVE model to soil gas TCE concentration rebound observations. Collectively, the field observations and the model predictions strongly support the observations that a substantial portion of the source contamination at the site has been removed by the SVE system and that the criteria for site closure have been met.

The influences of hydrologic regime (vadose zone or saturated zone), proximity to the source input (impacted or unimpacted soils), and soil weathering (field or laboratory-spiked soils) on the environmental availability U were examined. Environmental availability (availability for groundwater transport) was operationally defined using a sequential extraction technique and was applied to vadose zone, saturated zone, and background soils. For saturated zone locations, matched porewater-soil sets of field samples were collected, and data generated from these samples were used to examine U partitioning under field conditions. Laboratory batch sorption studies of uranyl ion to background soils were conducted as a function of pH. Subsequently, the soil used in the sorption study was subjected to sequential extraction to investigate the environmental availability in laboratory spiked samples. Based on sequential extraction behavior of U-impacted soils and background soils and the acidic plume chemistry, U concentrations in the first three sequential extraction steps [deionized water, CaCl (sub 2) , and acetic acid/Ca(NO (sub 3) ) (sub 2) ] were operationally defined as available, and the final two extraction steps (crystalline iron oxide and residual extraction steps) were operationally defined as unavailable. Based on this operational definition, soils impacted by the acidic U plume exhibited a greater fraction of available and total U. Vadose-zone soils had a smaller fraction of available U than corresponding saturated zone samples. Sequential extractions of U sorbed to background soils in a short-term laboratory experiment showed greater U availability compared with field soils collected within the contaminant plume. Field-derived K (sub d) values ranged from 0.1 to 300 L kg (super -1) and were highly correlated with porewater pH.

To that end, long-term experiments were conducted at the Savannah River Site (SRS), where a series of lysimeters containing sources of different Pu oxidation states were placed in the shallow subsurface and exposed to the environment for 2 to 11 yr. After the experiments, Pu activity concentrations were measured along vertical cores from the lysimeters. Plutonium distributions were anomalous in nature--transport from oxidized Pu sources was less than expected, and a small fraction of Pu from reduced sources moved more. Studies conducted with these lysimeter sediments indicated that surface-mediated, oxidation-reduction (redox) reactions may be responsible for the anomalies. This hypothesis is tested by performing transient Pu transport simulations that include retardation and first-order redox reactions on mineral surfaces within a steady-state flow field. These simulations affirm the consistency of the surface-mediated, redox hypothesis with observed Pu activity profiles below the source. Such profiles are captured well by a steady-state, net downward flow model. The redox model explains how Pu(V/VI) sources release activity that moves downward more slowly than expected, and how Pu(III/IV) sources result in a small fraction of activity that moves downward farther than expected. The calibrated parameter values were robust and well defined throughout all simulations. Approximate retardation factors for Pu(V/VI) were 15, and for Pu(III/IV) were 10,000. For these values, k (sub o) averaged 2.4X10 (super -7) h (super -1) ; k (sub r) averaged 7.1X10 (super -4) h (super -1) (standard deviations are 1.6X10 (super -7) h (super -1) and 1.6X10 (super -4) h (super -1) respectively).

Yet methods for estimating above- and below ground water storage include substantial uncertainties. This paper demonstrates that water levels in the Gordon aquifer (a confined aquifer at the USDOE Savannah River Site, near Aiken, SC) fluctuate in response to changes in total water storage. An increase in surface loading is known to cause a measurable increase in aquifer fluid pressure whenever the aquifer skeletal compressibility is sufficiently large. Water levels in the Gordon aquifer respond rapidly during precipitation events, which is consistent with increased loading that compresses the aquifer at depth. Instantaneous barometric and loading efficiencies of approximately 6 and 91%, respectively, are consistent with a poorly consolidated aquifer. Because the aquifer has a high loading efficiency, it behaves like a geological weighing lysimeter that appears to estimate water storage. Following precipitation events, aquifer water levels decline over time, presumably due to unloading by evapotranspiration plus net lateral water export. The water-storage signal is improved by incorporating (i) the lagged response between aquifer load and borehole water-level changes and (ii) the removal of periodic Earth tides.

Therefore, we conducted a series of field-scale experiments using tritiated water ( (super 3) H (super 1) HO), bromide (Br (super -) ), and two fluorobenzoates (2,4 Di-FBA, 2,6 Di-FBA) as tracers in the water-table aquifer on the USDOE's Savannah River Site (SRS), located on the upper Atlantic Coastal Plain. For each experiment, tracer-free groundwater was injected for approximately 24 h (56.7 L min (super -1) ) to establish a steady-state forced radial gradient before the introduction of a tracer pulse. After the tracer pulse, which lasted from 256 to 560 min, the forced gradient was maintained throughout the experiment using nonlabeled groundwater. Tracer migration was monitored using six multilevel monitoring wells, radially spaced at approximate distances of 2.0, 3.0, and 4.5 m from the central injection well. Each sampling well was further divided into three discrete sampling depths that were pumped continuously ( approximately 0.1 L min (super -1) ) throughout the course of the experiments. Longitudinal dispersivity (alpha (sub L) ) and travel times for (super 3) H (super 1) HO breakthrough were estimated by fitting the field data to analytical approximations of the advection-dispersion equation (ADE) for uniform and radial flow conditions. Dispersivity varied greatly between wells located at similar transport distances and even between zones within a given well, which we attributed to variability in the hydraulic conductivity at the study site. The radial flow equation generally described tritium breakthrough better than the uniform flow solution, as indicated by the coefficient of determination, r (super 2) , yielding lower alpha (sub L) while accounting for breakthrough tailing inherent to radial flow conditions. Complex multiple-peak breakthrough patterns were observed within certain sampling zones, indicative of multiple major flow paths and the superposition of resulting breakthrough curves. A strong correlation was found between alpha (sub L) and arrival times observed from one experiment to the next, indicative of the general reproducibility of the tracer results. Temporal moment analysis was used to evaluate tracer migration rate as an indicator of variations in hydraulic conductivity and flow velocity, as well as mass recovery and retardation for the ionic solutes compared with tritiated water. Retardation factors for Br (super -) ranged from 0.99 to 1.67 with no clear trend with respect to transport distance; however, Br (super -) mass recovery decreased with distance, suggesting that the retardation values are biased in terms of early arrival because of limited detection and an insufficient monitoring duration. Anion retardation was attributed to sorption by iron oxides. Similar results were observed for the FBA tracers. The assumption of conservative behavior for the anionic tracers would generally result in higher alpha (sub L) values and lower estimated flow velocities.

In the case of a former tritium extraction facility, building demolition produced a significant volume of rubble containing tritium. The contaminated debris comprises a heterogeneous mixture of coarse aggregate sizes, shapes, and internal tritium distributions. The rubble was disposed in unlined earthen trenches that were subsequently backfilled and exposed to normal infiltration. To forecast tritium flux to the water table, an unsteady dual-porosity model was developed to describe vadose zone leaching and transport. Tritium release was assumed to be controlled by diffusion within concrete, while advective and diffusive transport occur in the surrounding backfill. Rubble size and shape variations were characterized through a combination of physical measurement and photographic image analysis. For simplicity, the characterization data were reduced to an approximately equivalent distribution of one-dimensional slab thicknesses for representation in the dual-porosity formulation. Tritium flux to the water table from concrete rubble was predicted to be roughly 40% of that from uniformly contaminated soil. The lower flux is a result of slow release to soil pore water and a reduced effective trench conductivity from the presence of impervious concrete. At early times, tritium release from concrete in the lower trench is depressed by downward migration of tritium from overlying material. The pattern reverses at later times, when tritium is largely exhausted in the upper trench but higher residuals occupy the lower trench.

To fulfill this mission during the past 50 years SRS has operated five nuclear reactors, two large chemical separation areas, waste disposal facilities (landfills, waste ponds, waste tanks, and waste stabilization), and a large number of research and logistics support facilities. Contaminants of concern (COC) resulting from site operations include chlorinated solvents, radionuclides, metals, and metalloids, often found as complex mixtures that greatly complicate remediation efforts when compared with civilian industries. The objective of this article is to provide a description of the lithology and hydrostatigraphy of the SRS, as well as a brief history of site operations and research activities as a preface to the current special section of Vadose Zone Journal (VZJ) dedicated to SRS, focusing mainly on issues that are unique to the USDOE complex. Contributions to the special section reflect a diverse range of topics, from hydrologic tracer experiments conducted both within the vadose and saturated zones to studies specifically aimed at identifying geochemical processes controlling the migration and partitioning of specific contaminants (e.g., TCE, (super 137) Cs, U, and Pu) in SRS subsurface environments. Addressing the diverse environmental challenges of the SRS provides a unique opportunity to conduct both fundamental and applied research across a range of experimental scales. Hence, the SRS has been a pioneering force in several areas of environmental research and remediation, often through active interdisciplinary collaboration with researchers from other USDOE facilities, academic and federal institutions, and commercial entities.

Contaminated groundwater was collected in a pond and applied by spray irrigation to a catchment of mixed forest on Atlantic Coastal Plain soils. The objectives of this research project were to simulate tritium uptake by the vegetation and to determine if subsurface lateral flow at the sand-clay interface impacts tritium uptake by forest vegetation. To simulate water and tritium fluxes within the catchment, we developed a spatially explicit water and solute transport model. Vertical water flow was simulated within a grid using a layered capacitance model with lateral flow between cells dependent on head development and the local slope of the impeding clay layer. Tritium movement was simulated on a daily basis assuming complete mixing within a cell. The model was evaluated by comparing biweekly measurements of soil tritium activity and soil water content in 18 measurement clusters distributed across the irrigated portion of the catchment. Although lateral flow was predicted to occur locally, after 3 yr of tritium irrigation, the model predicted that lateral transfer of tritium was <70 m downslope of the irrigation area. Transient saturated conditions were observed and simulated to occur within parts of the catchment. Including the simulation of subsurface lateral flow of water and tritium under transient saturated conditions, however, did not significantly alter average tritium uptake predictions for the catchment.

In general, the influence of minerals in soil and groundwater clean-up can be grouped into their effects on fate and transport of contaminants, their use as amendments to facilitate contaminant destruction or stabilization, their indirect influence on remediation, and their role as sources of "natural" contaminants. The effect of mineralogy on fate and transport of contaminants is the most widely studied of these, but remains a challenging issue. Studies of contaminant adsorption range from single mineral to whole rock systems. However, integrating the results of these studies into generally applicable models remains elusive. This is because important factors such as reactive surface areas of minerals in aquifers, effects of natural variation in mineral composition, and alteration of minerals by plume chemistry are not well understood. The use of minerals as amendments to limit migration of contaminants is widespread. Apatite, zeolite, illite, calcite, and other minerals have been used in a variety of applications. To understand the effectiveness of this approach and its longevity requires a thorough knowledge of the reactions of amendment minerals in the plume chemistry. For example, use of hydroxyapatite may be affected by elevated concentrations of fluoride causing surface precipitation of less reactive fluorapatite. Reactions involving aquifer minerals can also complicate remediation. Technologies that rely on oxidation or reduction of contaminants must consider the presence of redox sensitive minerals that might interfere with the desired reaction. Other technologies can cause precipitation of minerals, lowering permeability. Finally, aquifer minerals are the source for naturally occurring contaminants. Elevated concentrations of radium in coastal plain aquifers result from dissolution of their uranium-bearing minerals. Dissolution of aquifer minerals can also release contaminants such as lead and arsenic in response to aquifer disturbance or plume chemistry.

This collision resulted in the release of several toxic chemicals to the environment, including chlorine. The dense and highly toxic cloud of chlorine gas that formed in the vicinity of the accident was responsible for 9 fatalities and caused injuries to more than 500 others. Transport model results depicting the forecast path of the ongoing release were made available to emergency managers in the county's Unified Command Center shortly after SRNL received a request for assistance. Support continued over the ensuing 2 days of the active response. The SRNL also provided weather briefings and transport/consequence assessment model results to responders from the South Carolina Department of Health and Environmental Control, the Savannah River Site (SRS) Emergency Operations Center, Department of Energy headquarters, and hazard material teams dispatched from the SRS. Operational model-generated forecast winds used in consequence assessments conducted during the incident were provided at 2-km horizontal grid spacing during the accident response. High-resolution Regional Atmospheric Modeling System (RAMS, version 4.3.0) simulation was later performed to examine potential influences of local topography on plume migration in greater detail. The detailed RAMS simulation was used to determine meteorology using multiple grids with an innermost grid spacing of 125 m. Results from the two simulations are shown to generally agree with meteorological observations at the time; consequently, local topography did not significantly affect wind in the area. Use of a dense gas dispersion model to simulate localized plume behavior using the higher-resolution winds indicated agreement with fatalities in the immediate area and visible damage to vegetation.

The MHSP is computed by averaging the EPT (numbers of Ephemeroptera, Plecoptera, Trichoptera taxa) and BI (a biotic index that reflects the pollution tolerances of individual taxa) to produce a bioclassification score. The MHSP produced low bioclassification scores that could falsely indicate environmental degradation in some undisturbed, high quality streams in the Sandhills ecoregion. This problem had two causes. The metrics (especially EPT) were significantly related to stream size, which potentially confounded stream size effects with environmental impacts, and the scoring criteria for EPT were too high for some Sandhills streams. We corrected these problems by developing new scoring criteria for Sandhills streams that utilized residuals from regressions of the metrics on stream width to normalize for stream size. The MHSP and related protocols are effective methods for assessing environmental quality, but allowances must be made for the effects of stream size and the potential ecological heterogeneity that naturally exists among streams in some ecoregions.

The objective of this study was to measure the release rate of Pu and the changes in the Pu oxidation states from these Pu sources with the intent to develop a reactive transport model source-term. Pu(III) and Pu(IV) sources had identical Pu concentration depth profiles and similar Pu release rates. Source release data indicate that Pu super(IV)(C sub(2)O sub(4)) sub(2) was the least mobile, whereas Pu super(VI)O sub(2)(NO sub(3)) sub(2) was the most mobile. Synchrotron X-ray fluorescence (SXRF) revealed that Pu was very unevenly distributed on the sediment and Mn concentrations were too low (630 mg kg super(-1)) and perhaps of the wrong mineralogy to influence Pu distribution. The high stability of sorbed Pu(IV) is proposed to be due to the formation of a stable hydrolyzed Pu(IV) surface species. Plutonium X-ray absorption near-edge spectroscopy (XANES) analysis conducted on sediment recovered at the end of the study from the Pu super(IV)(NO sub(3)) sub(4)- and Pu super(III)Cl sub(3)-amended lysimeters contained essentially identical Pu distributions: approximately 37% Pu(III), 67% Pu(IV), 0% Pu(V), and 0% Pu(VI). These results were similar to those using a wet chemistry Pu oxidation state assay, except the latter method did not detect any Pu(III) present on the sediment but instead indicated that 93-98% of the Pu existed as Pu(IV). This discrepancy was likely attributable to incomplete extraction of sediment Pu(III) by the wet chemistry method. Although Pu has been known to exist in the +3 oxidation state under microbially induced reducing conditions for decades, to our knowledge, this is the first observation of steady-state Pu(III) in association with natural sediments. On the basis of thermodynamic considerations, Pu(III) has a wide potential distribution, especially in acidic environments, and as such may warrant further investigation.

These trends along with technical and scientific developments underpin a variety of new environmental clean-up paradigms. Central to these new paradigms are new metrics for evaluating remedial actions with respect to environmental burden and collateral damage. For example, if we define water intensity as the amount of water necessary to remove one pound of contaminant we can then evaluate a groundwater remediation system with regard to resource conservation. Likewise we can evaluate the energy efficiency of a groundwater remediation system by studying the energy intensity or kWhr/pound of contaminant removed. And finally, the carbon intensity (lb CO sub(2)/lb contaminant) can be determined from the energy intensity using readily available data from the power industry. This paper introduces this new type of thinking through the analysis of a typical groundwater remedial action and relates it to the various spatial and temporal concentration regimes within a plume of contaminated groundwater and its' subsequent remediation. This new paradigm is also extended to other environmental actions and policies by considering the significance of risk transfer from one media to another.

The redox status and the general water chemistry of the oxidized and reduced treatments differed greatly, yet the influences of the amendments on contaminant stabilization were quite similar; both amendments significantly (p less than or equal to 0.05) reduced aqueous contaminant concentrations. Based on resin sorption studies and thermodynamic calculations, Ce is believed to exist primarily as cationic species and Co as cationic, neutral, and organically complexed species. Based on a series of selective extractions, almost 50% by weight of the Co and Pb were already strongly bound to the sediment, thereby limiting the potential (and need) of affecting additional immobilization through the use of amendments. Fe(0) and combined Fe(0) and apatite additions tended to increase the in situ desorption K sub(d) values more than apatite-only additions.

A common problem associated with pressure-based SVE design is overestimating the ZOI of the extraction well. As a result, design strategies based upon critical pore- gas velocity (CPGV) have become more common. Field tests were conducted at the Savannah River Site (SRS) to determine the influence of a vapor extraction well based upon both a pressure and pore- gas velocity design criterion. The results from these tests show that an SVE system designed based upon a CPGV is more robust and will have shorter cleanup times due to increased flow throughout the treatment zone. Pressure-based SVE design may be appropriate in applications where soil gas containment is the primary objective; however, in cases where the capture and removal of contaminated soil gas is the primary objective, CPGV is a better design criterion.

Escapement was greatest in the spring and early summer, with lake chubsucker Erimyzon sucetta dominating the escapement catch in early spring and several sunfishes Lepomis spp. dominating in late spring and early summer. Most of the escaping centrarchids were bluegill L. macrochirus, warmouth L. gulosus, and redbreast sunfish L. auritus in L Lake and warmouths, bluegills, dollar sunfish L. marginatus, and spotted sunfish L. punctatus in Par Pond. Escapement was enhanced by high reservoir water levels and surface discharge over the spillway. Escapement declined during periods of hypolimnetic release from bottom discharge gates. Location of the Par Pond discharge structure in the littoral zone rather than the pelagic zone as in L Lake contributed to greater escapement of littoral species in Par Pond. Species composition in the escapement catches and reservoirs was not significantly correlated. Relatively low escapement from L Lake and Par Pond compared with that in other reservoirs may have been related to the configuration of the discharge structures, low water levels during 2002, fish habitat preferences, species composition and abundance in the reservoirs, and low rates of discharge.

In aqueous systems, U(VI) is typically much more soluble than U(IV) due to the formation of various U(VI)-carbonato and U(VI)-hydrolysis species. These U(VI) species can be quite mobile in the environment. However, the adsorption of dissolved U to the solid phase and the microbial reduction of U(VI) to form sparingly soluble U(IV) oxides can limit U mobility in the aqueous environment. During the last century, there have been several anthropogenic activities that have altered the chemical form, distribution, and mobility of U in the environment. Examples of these activities include the release of depleted uranium projectiles during munitions firing, the concentration of U in soils due to irrigated agricultural activities, and those releases associated with the nuclear fuel cycle. This presentation will provide a review of U geochemistry followed by a presentation of the anthropogenic (source term) activities that have resulted in the release of U contamination into the environment, the geochemical behavior of U in these contaminated systems and some of the analytical techniques that have been used to characterize the geochemical speciation of U in these systems.

Actual Waste Testing AN - 20549944; 7401984 AB - Pretreatment processes at the Savannah River Site will separate 90 Sr, alpha- emitting and radionuclides (i.e., actinides) and 137 Cs prior to disposal of the high-level nuclear waste. Separation of 90 Sr and alpha-emitting radionuclides occurs by ion exchange/adsorption using an inorganic material, monosodium titanate (MST). Previously reported testing with simulants indicates that the MST exhibits high selectivity for strontium and actinides in high ionic strength and strongly alkaline salt solutions. This paper provides a summary of data acquired to measure the performance of MST to remove strontium and actinides from actual waste solutions. These tests evaluated the effects of ionic strength, mixing, elevated alpha activities, and multiple contacts of the waste with MST. Tests also provided confirmation that MST performs well at much larger laboratory scales (300 - 700 times larger) and exhibits little affinity for desorption of strontium and plutonium during washing.

Linear, quadratic, and lognormal regression models indicated that stream width was positively related to total number of taxa; number of Ephemeroptera, Plecoptera, and Trichoptera (EPT) taxa; and total number of organisms. Linear regression showed that the expected number of taxa at undisturbed sites ranged from 35 in 2.0 m wide streams to 64 in 16.0 m streams. Comparable values were 8-20 for EPT and 109-261 for number of organisms. Stream width was inversely related to biotic index values indicating a decrease in average organism tolerance with increasing stream size. ANCOVA showed that the effects of stream size were similar for disturbed and undisturbed sites. Rank correlations and multidimensional scaling (MDS) showed that Lepidoptera and Trichoptera were more abundant in larger streams and Annelida in smaller streams. Stream size related changes in benthic macroinvertebrate community composition are often ignored in bioassessment protocols; however, failure to adjust metrics for stream size can lead to erroneous conclusions. Adjustments are possible by analyzing regression residuals stripped of stream size related variance, dividing the area beneath the maximum taxa richness line into equal size units for metric scoring, or scaling metrics based on predicted reference values.

AN - 68747811; 16362965 AB - Monosodium titanate (MST) is an inorganic sorbent/ion exchanger developed for the removal of radionuclides from nuclear wastes. We investigated the ability of MST to bind Cd(II), Hg(II), Au(III), or the Au-organic compound auranofin to establish the utility of MST for applications in environmental decontamination or medical therapy (drug delivery). Adsorption isotherms for MST were determined at pH 7-7.5 in water or phosphate-buffered saline. The extent of metal binding was determined spectroscopically by measuring the concentrations of the metals in solution before and after contact with the MST. Cytotoxic responses to MST were assessed using THP1 monocytes and succinate dehydrogenase activity. Monocytic activation by MST was assessed by TNFalpha secretion (ELISA) with or without lipopolysaccharide (LPS) activation. MST adsorbed Cd(II), Hg(II), and Au(III) under conditions similar to those in physiological systems. MST exhibited the highest affinity for Cd(II) followed by Hg(II) and Au (III). MST (up to 100 mg/L) exhibited only minor (<25% suppression of succinate dehydrogenase) cytotoxicity and did not trigger TNFalpha secretion nor modulate LPS-induced TNFalpha secretion from monocytes. MST exhibits high affinity for biometals with no significant biological liabilities in these introductory studies. MST deserves further scrutiny as a substance with the capacity to decontaminate biological environments or deliver metals or metal compounds for therapeutic applications.

7029605 AB - One waste remediation process used at the Savannah River Site was the in-tank precipitation of the beta-emitting super(137)Cs from high-level waste (HLW) using sodium tetraphenylborate (NaTPB) followed by processing the resulting decontaminated filtrate into grout at the Saltstone Production Facility (SPF). A simple method was developed for the monitoring of tetraphenylborate (TPB) in high-level waste (HLW) containing up to 0.38 Ci/gal of super(137)Cs. Separation was achieved by extraction of the high sodium-bearing waste with acetonitrile followed by analysis using reversed-phase high performance liquid chromatography (HPLC). The sample preparation method allowed for the handling of an organic extraction layer that had 94% less acitivity than the HLW sample.

However, phosphate minerals naturally accumulate some heavy metals that may cause additional contamination of the environment if used improperly. Nine commercially available phosphate materials were evaluated for remediation of contaminated soil based on solubility, concentration of metal/metalloid impurities, and leachability of impurity metal/metalloids. The phosphate materials consisted of three groups: processed (i.e., fertilizers), mined (rock phosphates from different formations), and biogenic (ground fish bone). Processed and mined rock phosphates contained relatively high total concentrations of As, Co, Cr, and Cu but did not exceed the RCRA toxicity characteristic leaching procedure (TCLP) limits. Biogenic apatite contained much lower metal concentrations than processed and mined rock phosphate and was appreciably more soluble. By combining biogenic and mined phosphate it is possible to obtain a wide range of phosphate release rates, permitting rapid immobilization of contaminants while providing a slow release of phosphate for continued long-term treatment.

The facility was used to fabricate HEU fuel assemblies, lithium-aluminum target tubes, neptunium assemblies, and miscellaneous components for the SRS production reactors. The facility operated for more than 35 years. During this time thousands of uranium-aluminum alloy (U-Al) production reactor fuel tubes were produced. After the facility ceased operations in 1995, all of the easily accessible U-Al was removed from the building, and only residual amounts remained. The bulk of this residue was located in the equipment that generated and handled small U-Al particles and in the exhaust systems for this equipment (e.g., chip compactor, casting furnaces, log saw, lathes A & B, cyclone separator, FreonOcart, riser crusher, [mldr ], etc). The D&D project is likely to represent an important example for D&D activities across SRS and across the Department of Energy weapons complex. The Savannah River National Laboratory was tasked to conduct holdup assays to quantify the amount of HEU on all components removed from the facility prior to placing in solid waste containers. The super(235)U holdup in any single component of process equipment must not exceed 50 g in order to meet the container limit. This limit was imposed to meet criticality requirements of the low level solid waste storage vaults. Thus, the holdup measurements were used as guidance to determine if further decontamination of equipment was needed to ensure that the quantity of super(235)U did not exceed the 50 g limit and to ensure that the waste met the Waste Acceptance Criteria (WAC) of the solid waste storage vaults. Since HEU is an accountable nuclear material, the holdupassays and assays of recovered residue were also important for material control and accountability purposes. In summary, the results of the holdup assays were essential for determining compliance with the Waste Acceptance Criteria, Material Control & Accountability, and to ensure that administrative criticality safety controls were not exceeded. This paper discusses theg-ray assay measurements conducted and the modeling of the acquired data to obtain measured holdup in process equipment, exhaust components, and fixed geometry scrap cans. It also presents development work required to model new acquisition configurations and to adapt available instrumentation to perform the assays.

This action may be followed by a less aggressive remediation technology such as soil vapor extraction or "pump and treat" in the case of groundwater. Both of these stages reduces contaminant mass and thus flux of contaminant from the residual source zone to the point where it becomes mass transfer limited and only incremental gains are made toward site remediation. At this point ever increasing quantities of vapor or groundwater must be removed to remove the same amount of contaminant mass. Likewise ever increasing quantities of energy and time must be consumed to remove additional contaminant mass. This stage is the longest of the remediation stages and can last for decades. As a result new strategies and low energy technologies are needed to minimize the environmental impact and reduce cost at this final stage of remediation. The Savannah River National Laboratory has developed several technologies for use in this stage of remediation. These technologies are GeoSiphon, BaroBall, PHOSTER, and the Microblower. All of the technologies are powered by renewable energy and have been tested and implemented at the Savannah River Site across a wide variety of problems ranging from removal of soil vapor contaminated chlorinated volatile organic compounds to treatment of groundwater contaminated with dissolved metals.

When Pu(V) was added to a red subsurface sandy-clay-loam sediment collected near Aiken, South Carolina, 99% of the Pu sorbed to the sediment within 48 h. Throughout the study, > 94% of the Pu sub(aq) remained as Pu(V), whereas 2 orders-of-magnitude when the contact time was increased from 1- to 33-days, presumably the result of Pu(V) reduction to Pu(IV). The desorption studies were conducted with a sediment that had been in contact with Pu (originally as Pu super(IV)(NO sub(3)) sub(4)) for 24 years. At near neutral pH, a decrease of 1-pH unit resulted in almost an order-of-magnitude increase in the concentration of Pu sub(aq) (7.5 x 10 super(-) super(10) M at pH 7 and 3.6 x 10 super(-) super(9) M at pH 6). Similar to the sorption experiment, > 96% of the Pu sub(aq) was Pu(V/VI). The Pu sub(aq) concentrations from the desorption experiment were similar to those of the Pu(V) amended sorption studies that were permitted to equilibrate for 33 days, suggesting that the latter had reached steady state. The Pu sub(aq) concentrations as a function of pH followed near identical trends with literature solubility values for PuO sub(2)(am), except that the desorption values were lower by a fixed amount, suggesting either Pu sorption was occurring in this sediment system or that a more crystalline, less soluble form of Pu existed in the sediment than in the literature water-PuO sub(2)(am) system. Based on Pu sorption experiments and measured sediment surface charge properties as a function of pH, the latter explanation appears more likely. pH had a more pronounced effect on solubility and Pu sub(aq) concentrations than on sediment charge density (or Pu sub(aq) oxidation state distribution). Slight changes in system pH can have a large impact on Pu solubility and the tendency of Pu to sorb to sediment, thereby influencing Pu subsurface mobility.

A retention basin provided stable water flow to the system. Water retention time in the wetland system was approximately 48 hours, and the wetland cells operated at circumneutral pH. Vegetation development within the cells has been excellent. Copper removal efficiency was greater than 75 % from the start-up of the system, while mercury efficiency improved with maturation of the treatment cells. Sampling of the water course through the wetlands conducted during the fourth year of operation validated continued performance, and assessed the fate of a larger suite of metals present in the water. Copper and mercury removal efficiencies were still very high, both in excess of 80 % removal from the water after passage through the wetland system. Mercury removal continued along the entire water course through the system, while copper was removed almost immediately upon entering the wetland cells. Lead removal from the water by the system was 83 %, zinc removal was 60 %, and nickel was generally unaffected. Organic carbon in the water was also increased by the system and reduced the bioavailability of some metals. Operation and maintenance of the system continued to be minimal, and mainly consisted of checking for growth of the vegetation and free flow of the water through the system. The system was entirely passive, relying on gravity as the power source of water flow. No reportable permit exceedances have been experienced since the wetland began treating an outfall discharge.

The bed volume (BV=140) at the onset of breakthrough surpassed the design requirement of 100 BV at 50% breakthrough, and also corresponds to 99.96% cesium removal. Cesium elution with 0.5M HNO sub(3)was satisfactory with a peak BV of 2.5. The elution BV for C/C sub(0)=0.01 was 10, which is less than the target of 15 BV.

Sequential extraction data were used to evaluate remobilization and retention of Cu, Pb, Zn, Mn, and Fe in the wetland sediment. Remobilization of metals was determined by the Potentially Mobile Fraction (PMF) and metal retention by the Recalcitrant Factor (RF). The PMF, which includes water soluble, exchangeable, and amorphous oxides fractions, is the contaminant fraction that has the potential to enter into the mobile aqueous phase under fluctuating environmental conditions. PMF values were low for Cu, Zn, and Pb (13-27 %) and high for Fe and Mn (62-70 %). The RF, which includes crystalline oxides, sulfides or silicates and aluminosilicates, is the ratio of strongly bound fractions to the total concentration of elements in sediment. RF values ranged from 73-87 % for Cu, Zn, and Pb, indicating high retention in the sediment and from 30-38 % for Fe and Mn, indicating low retention. Contaminant retention, which is determined by solid phase metal speciation, determines the potential mobility and bioavailability of captured metals in wetland sediments; hence, their likelihood of being released if chemical, physical, or biological conditions within the wetland change.

Soil super(137)Cs activity concentrations were heterogeneous on small and large spatial scales and had a geometric mean of 253 (range 23-2110) Bq/kg dry weight. Mean super(137)Cs activity concentrations in composite cotton rat Sigmodon hispidus and cotton mouse Peromyscus gossypinus samples averaged 2480 (range 556- 6670) and 471 (range 96-1000) Bq/kg whole body dry weight, respectively. About 50% of the variance in cotton rat tissue super(137)Cs activity was explained by variation in soil super(137)Cs activity. Soil-to-animal dry weight concentration ratios averaged 6.0 for cotton rats and 1.2 for cotton mice and were generally similar to super(137)Cs concentration ratios for herbivorous, homeothermic animals from other contaminated ecosystems. In the RESRAD-BIOTA dose model, the default wet-weight concentration ratio for super(137)Cs in terrestrial animals is 110 resulting in an estimate of internal and external radiation doses to terrestrial biota that is 44 times more than the dose calculated with the actual measured wet-weight concentration ratio for cotton rats (1.6). These results show that site-specific concentration ratios can significantly affect the estimation of dose.

Even with many high-quality technical guidance references available, there continue to be challenges implementing MNA at some chlorinated solvent sites. The U.S. Department of Energy, as one organization facing such challenges, is leading a project that will incorporate developing concepts and tools into the existing toolbox for selecting and implementing MNA as a remediation option at sites with chlorinated solvent contamination. The structure and goals of this project were introduced in an article in the Winter 2004 issue of Remediation (Sink et al., 2004). This article is a summary of the three technical areas being developed through the project: mass balance, enhanced attenuation, and characterization and monitoring supporting the first two areas. These topics will be documented in separate reports available from the U.S. Department of Energy Office of Scientific and Technical Information at www.osti.gov.

Commercial units have been deployed at several locations in North America and worldwide since the mid-1990s, typically in arid or semiarid climates. A commercial spray evaporator was field tested at the U.S. Department of Energy's Savannah River Site in South Carolina to develop quantitative performance data under relatively humid conditions. A semiempirical correlation was developed from eight tests from March through August 2003. For a spray rate of 250 L/min (66 gpm) and continuous year-round operation at the Savannah River Site, the predicted average evaporation rate is 48 L/min (13 gpm).

The purpose of this experiment was to field-test the ability of this method to detect dense nonaqueous phase liquids (DNAPLs), specifically tetrachloroethene (PCE), known to contaminate the area. Five vertical electrode arrays (VEAs) were installed with approximately 15-ft (3 m) separations in and around the suspected source zone to depths of 72 ft (22 m), and measurements were carried out at seven nearest-neighbor panels. Amplitude and phase data were edited for quality and then inverted to form three-dimensional (3D) images. The comparatively small magnitude of the nonlinear resistivity Hilbert distortion allowed approximate linearized imaging of the 3D distribution of this quantity as well. Laboratory analysis of nearby soil contaminated in situ indicated that the NLCR response to the PCE-clay reaction is maximized near 50 mHz, leading to the development of a metric involving the phase and resistivity Hilbert distortion to infer the 3D distribution of PCE. Variations in PCE content were independently detailed at three drilling locations within the NLCR survey area using direct penetration-based soil-collection tools. Approximately 400 soil samples were collected and analyzed for chlorinated solvent mass composition at 1-ft (0.3-m) vertical intervals to compare with the NLCR-predicted distribution of DNAPL. The optimum performance for 1,000 mg/kg PCE was approximately 80% detection (true positives) with approximately 30% false alarms (false positives) at an effective resolution of 4 ft (1.2 m), or approximately 1/4 of the interwell separation. When smoothed to 12-ft (3.7 m) resolution (comparable to well spacing), detection was 100% with just 12% false alarms. NLCR successfully predicted the general distribution of PCE at parts-per-thousand soil-mass fractions, specifically widespread near-surface contamination and a zone of discontinuous stringers and pods below the source.

Simulant Testing AN - 20548970; 7411871 AB - High-level nuclear waste produced from fuel reprocessing operations at the Savannah River Site (SRS) requires pretreatment to remove 137 Cs, 90 Sr, and alpha-emitting radionuclides (i.e., actinides) prior to disposal. Separation processes planned at SRS include caustic side solvent extraction, for 137 Cs removal, and ion exchange/sorption of 90 Sr and alpha-emitting radionuclides with an inorganic material, monosodium titanate (MST). The predominant alpha-emitting radionuclides in the highly alkaline waste solutions include plutonium isotopes 238 Pu, 239 Pu, and 240 Pu. This paper provides a summary of data acquired to measure the performance of MST to remove strontium and actinides from simulated waste solutions. These tests evaluated the influence of ionic strength, temperature, solution composition, and the oxidation state of plutonium.

The apparatus is a transparent frame with sensors to measure the skin and bulk water temperature, the wind velocity, and the air temperature and humidity for periods of several days. The sensors are positioned within 1 m of the air-water interface and sample boundary layer variables every 2 s. Data for a 4-h period at midday are discussed, and the vertical fluxes of heat and momentum are calculated using bulk relationships for 1- and 5-min periods. It is shown that the measured water temperature at a depth of 1 cm correlates well with estimates based on the bulk heat flux. The skin temperature depression is calculated from the bulk heat and momentum fluxes and is found to vary between 0.4 degree and 0.5 degree C for the 4-h period and was in good agreement with the measured values. However, the calculated and measured skin temperatures were poorly correlated for both the 1- and 5-min averages. This is believed to be due to departures from the steady-state assumptions or to deficiencies in the theory.

Rhenium (surrogate for technetium in actual waste samples) breakthrough profiles were determined for three simulant compositions, which are representative of the basic waste categories requiring treatment in the Hanford River Protection Project Waste Treatment Plant. Considerable loading performance variability was observed between the three waste types, although the resin is effective at rhenium removal from each solution. Careful and frequent analysis during elution studies conducted at the conclusion of the column loading tests confirmed that sodium nitrate and sodium perrhenate ion pairs are primary sorbing species on SuperLig registered 639 resin. Furthermore, it was discovered that potassium nitrate and potassium perrhenate salts are significant competitors for sorption sites on the resin. Successive desorption profiles were identified for all four salt species during elution tests. Integration of the desorption profiles revealed that the resin is selective for removal of the potassium salts over the sodium salts.

To study long-term Pu mobility, four 52-L lysimeters filled with sediment collected from the Savannah River Site near Aiken South Carolina were amended with well characterized solid Pu sources (PuIIICl sub(3), PuIV(NO sub(3)) sub(4), PuIV(C sub(2)O sub(4)) sub(2), and PuVIO sub(2)(NO sub(3)) sub(2)) and left exposed to natural precipitation for 2 to 11 years. Laboratory studies showed that the sediment quickly reduced Pu(V) to Pu(IV) (the pseudo-1st order reduction rate constant, k'obs, was 0.11 h-1). Of particular interest was that this same sediment could be induced to release very low concentrations of sorbed Pu under oxidizing conditions, presumably by oxidation of sorbed Pu(IV) to the more mobile Pu(V) species. Pu oxidation state distribution in the Pu(III) and Pu(IV) lysimeters sediments (clay fraction primarily kaolinite, hematite, and goethite; pH = 6.3) were similar, consisting of 0% Pu(III), >92% Pu(IV), 1% Pu(V), 1% Pu(VI), and the remainder was a Pu polymer. These three lysimeters also had near identical sediment Pu concentration profiles, where >95% of the Pu remained within 1.25 cm of the source after 11 years; moving at an overall rate of 0.9 cm yr-1. As expected, Pu moved more rapidly through the Pu(VI) lysimeter, at an overall rate of 12.5 cm yr-1. Solute transport modeling of the sediment Pu concentration profile data in the Pu(VI) lysimeter indicated that some transformation of Pu into a much less mobile form, presumably Pu(IV), had occurred during the course of the two year study. This modeling also supported previous laboratory measurements showing that Pu(V) or Pu(VI) reduction was five orders of magnitude faster than corresponding Pu(III) or Pu(IV) oxidation. The slow oxidation rate (1 x 10-8 hr-1; t1/2 = 8,000 yr) was not discernable from the Pu(VI) lysimeter data that reflected only two years of transport but was readily discernable from the Pu(III) and Pu(IV) lysimeter data that reflected 11 yr of transport. Micro-SXRF maps of the lysimeter sediments indicated that Pu tended to exist independently of Fe or Mn. Micro-XANES indicated that the Pu remained in the +3 and +4 oxidation states.

N1 - Last updated - 2016-12-21 ER - TY - JOUR T1 - Biological Assessment of Slope Wetlands on the Coastal Plain of South Carolina AN - 17623849; 6257491 AB - Slope wetlands occur where groundwater emerges from hillsides to create shallow pools. These wetlands may be the initial point of contact between biota and emerging contaminated groundwater. We sampled several slope wetlands on the upper coastal plain of South Carolina that received contaminated groundwater and compared them to undisturbed slope wetlands. All of the wetlands supported a variety of insects, especially midge larvae and other Diptera, annelid worms, and aquatic beetles. Some supported large numbers of mites and copepods, and a few supported salamanders. Most taxa were tolerant of harsh conditions such as low dissolved oxygen and pH. Assemblage composition varied among wetlands due to differences in hydroperiod and likelihood of being flooded by nearby streams. Also important was the lack of shading in some disturbed wetlands, which permitted the growth of filamentous algae, sphagnum moss, and other plants. Few metrics commonly used for impact assessment differed between disturbed and undisturbed wetlands. High natural variability among slope wetlands and the natural tolerance of many slope wetland organisms may complicate the development of slope wetland multimetric indices, although such indices may be useful for identifying severely impacted wetlands.

The shallow Tertiary sediments consist primarily of interbedded and interfingering fluvial, deltaic, and shallow-marine sediments. Cone penetration testing is relatively inexpensive and does not require disposal of drilling fluid or cuttings. At the Savannah River Site, CPT is typically used to obtain depth-discrete groundwater samples and small-diameter permeability samples, and to define hydrostratigraphic horizons. The focus of this study is an environmental waste site where CPT at 139 locations was used to define contaminant plumes and hydrostratigraphy over an 8-km2 (3-mi2) area, instead of conventional borehole techniques (e.g., monitoring wells, cores, electric well logs, slug, and pumping tests). This investigation used the CPT lithologic data to predict hydraulic conductivity variations in hydrostratigraphic zones of the uppermost aquifer unit. The method developed involves correlating tip resistance, sleeve resistance, and pore-pressure measurements to fines (mud, silt, and clay) content and hydraulic conductivity. Predicted fines content at the scale of the CPT measurements (0.03 m; 0.1 ft) are then categorized into high, medium and low conductivity and upscaled to the flow model resolution using a geostatistical approach. The resulting model conductivity field provides a realistic representation of aquifer heterogeneity in coastal-plain sediments and significantly improves groundwater modeling predictions. Subsequent contaminant transport simulations compare well with field data.

These systems consisted of an in-situ treatment cell located in an area of higher hydraulic head and a siphon connecting the cell to a surface stream at a lower hydraulic head. The siphon induced contaminated groundwater flow through a permeable treatment media in the cells and transported the treated water to the discharge points in a surface stream. The hydraulic head available to drive the systems is divided between the head losses associated with the aquifer-treatment cell and siphon. Six different treatment cell configurations and seven different siphon configurations have been hydraulically evaluated in association with the two pilot-scale systems and are described herein. These pilot-scale systems demonstrated that GeoSiphon (super TM) systems can treat any contaminant for which an appropriate permeable treatment media is available and can be applied to shallow groundwater contaminant plumes (no deeper than 7.6 m [25 ft]), where at least a few feet of head differential can be exploited. The systems could typically be applied in flood plains.

AN - 67362974; 15650588 AB - At the Savannah River Site, emergency response computer models are used to estimate dose following releases of radioactive materials to the environment. Downwind air and ground concentrations and their associated doses from inhalation and ground shine pathways are estimated. The emergency response model (PUFF-PLUME) uses real-time data to track either instantaneous (puff) or continuous (plume) releases. A site-specific ingestion dose model was developed for use with PUFF-PLUME that includes the following ingestion dose pathways pertinent to the surrounding Savannah River Site area: milk, beef, water, and fish. The model is simplistic and can be used with existing code output.

Largemouth bass were relatively mobile in lower Steel Creek and the portion of the Savannah River near Steel Creek, and there was considerable movement between these two habitats. Largemouth bass had home ranges of about 500 linear meters of shoreline in the Savannah River but sometimes moved long distances. Such movements occurred primarily during the spawning season, largely upstream, and increased when water levels were changing or elevated. However, approximately 90% of the largemouth bass observations were within 10 km of Steel Creek. The total quantity of super(137)Cs transported into the Savannah River by largemouth bass was much less than transported by water and suspended sediments discharged from Steel Creek. The authors conclude that largemouth bass from the Savannah River Site are unlikely to be responsible for long distance dispersal of substantial radiological contamination in the Savannah River.

The single-domain model (SDM), employing field-scale dispersion, and the dual-domain model (DDM), employing local hydrodynamic dispersion and exchange between domains having large hydraulic conductivity contrasts, are well-known examples. In this paper, the two modeling approaches are applied to tritium migration from the H-area seepage basins to a nearby stream--Fourmile Branch--at the Savannah River Site. This location has been monitored since 1955, so an extensive dataset exists for formulating realistic simulations and comparing the results to data. It is concluded that the main parameters of both models are scale-dependent, and methods are discussed for making initial estimates of the DDM parameters, which include mobile/immobile porosities and the mass exchange coefficient. Both models were calibrated to produce the best fit to recorded tritium data. When various attributes of the dataset were considered, including cumulative tritium activity discharged to Fourmile Branch, plume arrival time, and plume attenuation due to closure of the seepage basins in 1988, the DDM produced results superior to the SDM, while causing no unrealistic upgradient dispersion. A sensitivity analysis showed that only the DDM was able to accurately produce both the instantaneous activity discharge and cumulative activity with a single parameter set. This is thought to be due to the advection-dominated nature of transport in natural porous media and the realistic treatment of this type of transport in the DDM relative to the SDM.

The model was used to evaluate radon flux at the land surface so that it could be compared to the established instantaneous flux limit of 20 pCi/m2-s. Rn-222 was the only radon isotope considered since it is the only one with a sufficiently long half-life long that it can diffuse through from the waste disposal zone through air-filled pores to the land surface above the facility before subsequent decay occurs. The numerical model PORFLOW (ACRI, Inc.) was selected to perform the simulations because of its ability to incorporate the radioactive decay chains leading to the in-growth of Rn-222 in addition its ability to simulate multi-phase contaminant transport. The model was gridded to allow an accurate representation of both the waste disposal zone and the closure cap that will cover the facility following permanent closure. Since Rn-222 exists in the gaseous phase, transport of Rn-222 was attributed entirely to diffusion through the air-filled pore space of both the waste disposal zone and the overlying soil cover. Porous media material properties were selected from the range of plausible values such that simulation results were both reasonable and conservative with respect to predicting whether the established radon emanation limit would be exceeded. Likewise, boundary conditions were selected to insure that reasonable but conservative results were obtained. Each radioisotope that eventually leads to the formation of Rn-222 (Ra-226, Th-230, U-234, U-238 and Pu-238) was evaluated separately using a unit source term such that the results could be utilized to establish reasonable and somewhat conservative facility disposal limits for each parent.

The estimate was derived from an in situ aquifer titration done to evaluate remediation of an acidic plume by injection of alkaline solutions. The plume is associated with the F-Area Seepage Basins on the Savannah River Site in South Carolina and contains elevated concentrations of Sr-90, I-129, Tc-99, uranium isotopes, and several contaminant metals. The aquifer is sandy with less than 5% clay-sized material. For the aquifer test, a solution of sodium hydroxide and sodium bicarbonate with a pH of 10 and an alkalinity of 5.2 X 10 (super -3) eq/L was injected into the aquifer. An extraction well located approximately 30 meters down gradient from the injection well was pumped at a rate of 60 liters/minute during the test. Regular pH measurements of the extracted water yielded a titration curve for the aquifer that was compared to modeled titration curves to estimate effective surface area. The modeled titration curves were constructed using the U.S.G.S. equilibrium geochemistry code PHREEQC. X-ray diffraction analysis of 5 core samples showed aquifer mineralogy to be dominated by quartz, kaolinite, and hematite. Bulk chemistry of these samples was obtained using X-ray fluorescence spectroscopy. A normative mineralogy of 21 mg/g kaolinite, 12 mg/g hematite, and 970 mg/g quartz was then calculated from these data. The hypothetical surface used in the model was based on these data, literature data on mineral surface area, and literature values for acidity constants. To estimate effective surface area of the aquifer, the titration test data were compared to a family of titration curves in which effective surface area was varied. This provides a method to estimate a fundamental aquifer property that is difficult to measure. The approach also demonstrates that important information about an aquifer can often be obtained from field tests that were not specifically designed for this purpose.

After a disposal trench is filled, a long-term cover is constructed to prevent surface water infiltration and human access. Significant buried waste subsidence can compromise long-term cover integrity, resulting in increased costs and human-health and environmental risks. For the disposal system evaluated in this study, up to 15 ft. of subsidence is anticipated, primarily related to waste-container void space and low-density waste. An evaluation of long-term subsidence and its implications for long-term cover stability for this in-use trench has been performed, incorporating geotechnical, geologic and corrosion data. A buried waste container and adjacent soil were excavated to determine corrosion types, rates and environment. These data were used to develop three scenarios projecting future container structural-strength loss. A parametric study was performed to summarize near- and long-term geologic, seismic, and climatic data, waste container and trench construction characteristics, and develop a trench geotechnical conceptual model. Using all this information, finite element modeling was performed for both dynamic compaction of the waste containers prior to significant corrosion and final cap construction, and for long-term subsidence (without dynamic compaction) at various degrees of container corrosion. Modeling results match well with field observations for dynamic compaction, and initial results for long-term corrosion-related subsidence seem reasonable. Ongoing efforts include field corrosion monitoring to narrow-down the future time frame for container structural-strength loss. These data aid in evaluating long-term cover system maintenance/repair costs and human-health and environmental risks.

AN - 67013510; 15506218 AB - High-level waste (HLW) is a waste associated with the dissolution of spent nuclear fuel for the recovery of weapons-grade material. It is the priority problem for the U.S. Department of Energy's Environmental Management Program. Current HLW treatment processes at the Savannah River Site (Aiken, SC) include the use of monosodium titanate (MST, with a similar stoichiometry to NaTi2O5 x xH2O) to concentrate strontium (Sr) and actinides. The high affinity of MST for Sr and actinides in HLW solutions rich in Na+ is poorly understood. Mechanistic information about the nature of radionuclide uptake will provide insight about MST treatment reliability. Our study characterized the morphology of MST and the chemistry of sorbed Sr2+ and uranium [U(VI)] as uranyl ion, UO2(2+), on MST, which were added (individually) from stock solutions of Sr and 238U(VI) with spectroscopic and transmission electron microscopic techniques. The local structure of sorbed U varied with loading, but the local structure of Sr did not vary with loading. Sorbed Sr exhibited specific adsorption as partially hydrated species whereas sorbed U exhibited specific adsorption as monomeric and dimeric U(VI)-carbonate complexes. Sorption proved site specific. These differences in site specificity and sorption mechanism may account forthe difficulties associated with predicting Sr and U loading and removal kinetics using MST.

To provide a technical basis to permit the waste treatment facility, a relatively organic-rich Hanford Tank 241-AN-107 waste simulant was spiked with 14 target volatile, semi-volatile, and pesticide compounds and evaporated under vacuum in a bench-scale natural circulation evaporator fitted with an industrial stack off-gas sampler at the Savannah River National Laboratory. An evaporator material balance for the target organics was calculated by combining liquid stream mass and analytical data with off-gas emissions estimates obtained using U.S. Environmental Protection Agency (EPA) SW-846 Methods. Volatile and light semi-volatile organic compounds (1 mm Hg vapor pressure) in the waste simulant were found to largely exit through the condenser vent, while heavier semi-volatiles and pesticides generally remain in the evaporator concentrate. An OLI Environmental Simulation Program (licensed by OLI Systems, Inc.) evaporator model successfully predicted operating conditions and the experimental distribution of the fed target organics exiting in the concentrate, condensate, and off-gas streams, with the exception of a few semi-volatile and pesticide compounds. Comparison with Henry's Law predictions suggests the OLI Environmental Simulation Program model is constrained by available literature data.

Strains AJ and TD also use ethene and ethylene oxide as growth substrates. Strain AJ contained a linear megaplasmid (approximately 260 kb) when grown on VC or ethene, but it contained no circular plasmids. While strain AJ was growing on ethylene oxide, it was observed to contain a 100-kb linear plasmid, and its ability to use VC as a substrate was retained. The linear plasmids in strain AJ were cured, and the ability of strain AJ to consume VC, ethene, and ethylene oxide was lost following growth on a rich substrate (Luria-Bertani broth) through at least three transfers. Strain TD contained three linear plasmids, ranging in size from approximately 90 kb to 320 kb, when growing on VC or ethene. As with strain AJ, the linear plasmids in strain TD were cured following growth on Luria-Bertani broth and its ability to consume VC and ethene was lost. Further analysis of these linear plasmids may help reveal the pathway for VC biodegradation in strains AJ and TD and explain why this process occurs at many but not all sites where groundwater is contaminated with chloroethenes. Metabolism of VC and ethene by strains AJ and TD is initiated by an alkene monooxygenase. Their yields during growth on VC (0.15 to 0.20 mg of total suspended solids per mg of VC) are similar to the yields reported for other isolates (i.e., Mycobacterium sp., Nocardioides sp., and Pseudomonas sp.).
