TY - JOUR T1 - Effect of Radiation Propagation Time on Criticality Accident Alarm Response AN - 1567059083; 20460243 AB - The design of a Criticality Accident Alarm System (CAAS) must include consideration for a variety of parameters. The most significant contributors to the design are the nature of activities being conducted; the possible types and forms of fissile materials in use; the size, shape, and makeup of the facility structure; the location of the CAAS detectors; and the detection and alarm logic to be implemented.

An extensive evaluation of several procedures by Dobry et al. concluded that both the Simplified Version of the Rayleigh Procedure and the Successive Use of Two-Layer Solution by Madera give errors of less than 10% for all of the 76 representative soil profiles considered in the evaluation. The simplified Rayleigh procedure is iterative and requires an initial estimate of the mode shape. The Madera procedure is based on the solution of a two-layer system, usually obtained from charts. In this paper the solution charts are replaced by approximate relations for implementation on a spreadsheet. Since the Madera procedure calculates only the fundamental period, mode shapes need to be calculated by other means. The Madera procedure is extended to calculate mode shapes and modal participation factors of layered soil profiles. Unlike the simplified Rayleigh procedure , the proposed solution incorporates the different densities of the layers and gives direct results without iterations. The proposed solution can be considered a simpler alternative to the Rayleigh method for shear beams or soil columns.

Performance-based design has been promoted as the solution. Performance-based design is simply a strategy for multiple designs for pairs of specific ground motion intensities and damage states. In general, four specific ground motion exceedance levels and four specific performance limit states are considered. Since for earthquake risk management the real issues are risk and reliability, this strategy is not a sufficient basis for making informed decisions. Earthquake risk management needs information regarding the failure probability of structures for any pre-selected limit state under all possible ground motions. This paper establishes the basis and methods for a risk-consistent design. Stakeholders are divided into two groups: those that have a responsibility for public health and safety, and those primarily focused on mitigating economic consequences. Public health and safety is not restricted herein to life-safety or collapse prevention performances. In general, public health and safety establish minimum requirements, which are mandated by jurisdictional authorities. The other stakeholders can only select to exceed these minimum requirements. Design decisions are separated into technical solutions by engineers, and risk management by stakeholders. Stakeholders have the responsibility for making risk decisions. The responsibility of the engineer is to deliver these expectations using appropriate methods of analysis, design and construction.

Defense Nuclear Facilities Safety Board, Technical Report, February 2001 AN - 17877692; 5116171 AB - The goal of any nuclear criticality safety program is to prevent inadvertent nuclear criticality. To this end, there are several fundamental areas such a program must address: the analysis of criticality hazards and the development of adequate controls for those hazards, implementation of the criticality controls in facility processes, and feedback and improvement including the maintenance of controls to ensure their integrity and reliability over time. The American National Standards Institute/American Nuclear Society 8.x series of national consensus standards and relevant Department of Energy (DOE) directives outline in detail the expectations and suggested methods for developing and implementing criticality controls. The guidance provided with respect to maintaining the controls, however, is incomplete. This incomplete guidance has resulted in some divergence of opinion within the DOE complex as to what level of approval and stewardship is appropriate for criticality controls and how they should relate to a facilitys Safety Analysis Report (SAR) and Technical Safety Requirements (TSRs). This issue is treated at length in this report, and a suggested approach is outlined. To better understand the processes being used in the field to develop, implement, and maintain criticality controls, the staff of the Defense Nuclear Facilities Safety Board recently conducted a series of reviews throughout the DOE complex. Also in recent months, DOE performed a series of criticality safety reviews under the sponsorship of the Deputy Assistant Secretary for Oversight. The high-level DOE reviews were aimed at identifying potential vulnerabilities within the DOE complex similar to those that led to the criticality in Tokaimura, Japan, in September 1999. Neither of these reviews revealed imminent criticality safety hazards in the complex. Both, however, identified several areas for improvement.

This expectation, which is simple to articulate, has proven difficult to realize. DOE and its contractors have had even more difficulty in agreeing upon the required format and content of the reports that document safety analyses. To improve the analysis and communication of the bases for safe operations at defense nuclear facilities, Order 5480.23 (U.S. Department of Energy, 1992) sets forth expectations for a document called a Safety Analysis Report (SAR). These expectations include expanding the documentation of safety bases beyond the traditional focus on hardware designed to protect the public to include all elements of the safety system (e.g., procedures, training, and management) and to encompass protection for workers and the environment. DOE realized that such a shift would require time to implement, even though it would be desirable to start accruing the benefits as soon as possible.

It is now established that at many nuclear facilities, fires are the dominant source of risk to workers and the public. This is especially true at aging facilities and at facilities undergoing decommissioning. In past decades, several major fires have occurred at defense nuclear facilities. While no such fires have occurred in more recent times, this experience should not lead to complacency. A single major fire could result in serious damage to the DOE nuclear program and in the worst case, cause harm to workers or the public. This report reviews technical concepts and principles important to maintaining the quality of DOE's fire protection program. The following topics are covered: Safety analysis, fire hazards analysis, and safety controls; Safety system classification and defense in depth; Emergency planning; Criticality; Configuration management; Performance criteria and reporting; Assessment and inspection findings; Professional staff; Fire departments; Research on fire phenomena; DOE and its predecessor agencies have had a good record on fire safety. This performance record must be continued into the indefinite future by rededication to the principles set forth in this report.

DOE is proposing a melt and dilute process that does not appear to be based on a comprehensive consideration of safety, technical certainty, and cost. The enclosed Boards staff report evaluates the spent fuel inventory at SRS and the processing alternatives for its disposal. The report is provided for further consideration of this matter as DOE proceeds in its selection of a disposition alternative. The report concludes that DOE should look for ways of accelerating the consolidation of aluminum spent fuel at SRS and maximize the use of its existing processing capabilities, at least until the year 2010, to dispose of this unique spent fuel. As more information is gained regarding the expected type and quantity of research reactor spent fuel that will be received after 2010, DOE can better evaluate alternatives for continued disposal of this spent fuel.
