本报告总结了桑迪亚国家实验室 (SNL) 根据 FIN A1165（性能评估技术援助）为美国核管理委员会 (NRC) 就与高放废物处置库性能评估相关的不确定性所开展的工作。本报告的目的是总结根据 FIN A1165 开展的不确定性主题领域的工作。许多不同类型的不确定性都会影响 HLW 存储库的性能。在绩效评估中，应识别和考虑这些不确定性，并在可行的范围内量化和减少。通常，不同类型的不确定性分为三大类：处置系统未来状态的不确定性；模拟处置系统行为所需模型的不确定性；以及系统分析所需的数据、参数和系数的不确定性。本报告涵盖了所有三个主要类别的不确定性。仅提供了一个简短的概述，其中大量引用了 SNL 报告，其中详细讨论了不同的不确定性主题；因此，本报告不是一份独立的报告。管理人员可以使用该报告来熟悉有关 HLW 存储库性能不确定性的问题，技术人员也可以使用该报告来回顾 SNL 在该领域为 NRC 所做的工作。 52 条参考文献。« 更少
This report culminates work performed by Sandia National Laboratories (SNL) for the US Nuclear Regulatory Commission (NRC) under FIN A1165 (Technical Assistance for Performance Assessment) on uncertainties associated with performance assessment of HLW repositories. The purpose of this report is to summarize the work in the topical area of uncertainty conducted under FIN A1165. Many different types of uncertainty can affect the performance of an HLW repository. In a performance assessment, these uncertainties should be identified and considered, and to the extent practicable, should be quantified and reduced. Conventionally, the different types of uncertainty are classified in three major categories: uncertainty in the future state of the disposal system; uncertainty in models needed to simulate the behavior of the disposal system; and uncertainty in data, parameters, and coefficients needed for the analysis of the system. All three major categories of uncertainty are covered in this report. Only a short overview is presented with numerous references to SNL reports where different uncertainty topics are discussed in detail; as such, this report is not a stand-alone report. The report can be used by managers to familiarize themselves with the issues regarding uncertainty in HLW repository performance and technical staff as a reviewmore » of SNL's work for NRC in this area. 52 refs.« less
