Abstract

This paper provides an overview of the U.S. Nuclear Regulatory Commission’s (NRC’s) project to develop a technical report summarizing the most important insights from its three State-of-the-Art Reactor Consequence Analyses (SOARCA) project uncertainty analyses (UAs). The NRC, with Sandia National Laboratories, has completed three UAs as part of the SOARCA project, for three different operating reactor types in three different locations in the United States. The SOARCA UAs included an integrated evaluation of uncertainty in accident progression, radiological release, and off-site health consequence projections. These three UAs are currently documented in three detailed reports. The NRC is currently developing a technical overview report summarizing the important insights from the three SOARCA UAs. The purpose of the NRC summary is to provide a useful reference for regulatory applications that require the evaluation of off-site consequence risk from beyond-design-basis-event severe accidents. Examples include regulatory and cost-benefit analyses that rely on off-site consequence projections using the MELCOR Accident Consequence Code System (MACCS) code, in conjunction with MELCOR for source term characterization. This paper provides an overview and discusses the overall scope and methodology of the SOARCA UAs and the approach for the summary report currently under development.

最先进的反应堆后果分析项目:电站停电情景的不确定性分析

摘要

本文概述了美国核监管委员会(NRC)的一项项目,该项目旨在编制一份技术报告,总结其三项最先进的反应堆后果分析(SOARCA)项目不确定性分析(UAs)的最重要见解。NRC与桑迪亚国家实验室(Sandia National Laboratories)合作,已完成了三个UA,作为SOARCA项目的一部分,用于美国三个不同地点的三种不同运行反应堆类型。SOARCA UA包括对事故进展,放射线释放和场外健康后果预测的不确定性的综合评估。目前,这三个UA记录在三个详细报告中。NRC目前正在开发一份技术概述报告,总结来自三个SOARCA UA的重要见解。NRC摘要的目的是为需要评估超出设计基准事件的严重事故造成的场外后果风险的监管应用提供有用的参考。示例包括监管和成本效益分析,这些分析依赖于使用MELCOR事故后果代码系统(MACCS)代码结合MELCOR进行源术语表征的场外后果预测。本文提供了概述,并讨论了SOARCA UA的总体范围和方法以及当前正在开发的摘要报告的方法。示例包括监管和成本效益分析,这些分析依赖于使用MELCOR事故后果代码系统(MACCS)代码结合MELCOR进行源术语表征的场外后果预测。本文提供了概述,并讨论了SOARCA UA的总体范围和方法以及当前正在开发的摘要报告的方法。示例包括监管和成本效益分析,这些分析依赖于使用MELCOR事故后果代码系统(MACCS)代码结合MELCOR进行源术语表征的场外后果预测。本文提供了概述,并讨论了SOARCA UA的总体范围和方法以及当前正在开发的摘要报告的方法。
