性能评价(PA)是风险评估在核废物地质处置领域中的应用。PA原是用作定量地展示处置场的工程与天然屏障性能的手段,其目的是最终证明处置系统的安全性。为此PA的最高指导思想是国际上公认的原则和指南。在实际应用中,PA与处置项目的几个主要部分都有联系,包括废物描述、处置概念到场址选择和描述。因此,PA在核废物管理项目中占有很特殊的位置:PA可以作为决策工具,辅助处置项目的计划和管理,使项目能够有效益地进行,以达到预期的目标。从自上而下的视角介绍PA,包括方法论、模式、处理不确定性等。还为中国科学家列出了一些具体的建议。

Performance Evaluation (PA) is the application of risk assessment in the field of geological disposal of nuclear waste. PA was originally used as a means of quantitatively demonstrating the engineering and natural barrier performance of the disposal site, with the aim of ultimately demonstrating the safety of the disposal system. To this end, PA’s guiding principle is internationally accepted principles and guidelines. In practice, the PA is linked to several major parts of the disposal project, including waste description, disposal concept to site selection and description. Therefore, PA occupies a very special place in nuclear waste management projects: PA can be used as a decision-making tool to assist in the planning and management of the project so that the project can be carried out effectively and achieve the expected goal. Introducing PA from a top-down perspective, including methodologies, models, handling uncertainty and more. Chinese scientists also made some specific suggestions.
