摘　　要：概率安全评价(PSA)方法中故障树分析法是一种评价系统可靠性的有效方法,通过对系统建模计算分析可以加深对系统设计的理解,以及帮助找出系统设计的薄弱环节,从而在条件允许的情况下针对性地进行相应的改进与调整,为提高核电厂整体的安全性提供思路。本文主要就秦山二期扩建项目以及方家山项目中关于电力系统故障树分析中遇到的两个问题进行比较分析,从定性和定量的角度进行对比,从而得出结论。The fault tree analysis is a useful method to give a assessment on the system reliability in NPP design and operation stage. It helps to understand the system design and find out the weaknesses of the system based on the model and analysis result, and it also provides a means to improve the system reli- ability. This paper mainly discusses two issues on power system reliability analysis in Qinshan Phase Two NPP and Fangjiashan NPP, and provides the conclusion from qualitative and quantitative aspects.
