摘要

计算核电厂构筑物、系统和部件(SSC)的高置信度低失效概率抗震能力值(HCLPF)是地震概率安全评价(SPSA)、地震裕度评价(SMA)的一个重要步骤。介绍在工程上常用的3种计算SSC HCLPF值的方法:概率易损性方法、保守的确定性失效裕度(CDFM)方法以及通过试验数据获取HCLPF值的方法,并对比研究近年来在计算HCLPF值方法上的新进展,最后给出了计算HCLPF值的一些建议。
Calculation of the HCLPF value of structure,system and component(SSC) in nuclear power plants(NPPs) is an important process for seismic probability safety assessment(SPSA) and seismic margin assessment(SMA).In this paper,three methods for calculation of the HCLPF value of SSC are presented,such as fragility analysis,conservative deterministic failure margin(CDFM),and HCLPF value based on test.The recent progresses in calculation of the HCLPF value of SSC are investigated.Finally some suggestions for the calculation of the HCLPF value of SSC are proposed.
