摘要
在核电站设计和运行阶段概率安全分析(PSA)是必不可少的一种工具,而对PSA相关设备的可靠性分析是其中重要的一环。截至2013年底,秦山三厂两台机组累计运行约21堆年,积累了大量的运行、维修和试验等数据,需要从这些数据中整理分析出设备的失效数据,从而为PSA分析提供参数,并为核电站的设备维护提供指导。论文介绍了失效分析的过程,对失效数据进行了统计分析,并指出了失效分析时遇到的问题和建议。
Probability Safety Assessment(PSA) is one of the essential tools during the design and operation period of nuclear power station,and the reliability analysis for PSA related equipments is one of the essential tools. By the end of 2013,the two units of Qinshan 3rd nuclear power station accumulated run about 21 years,accumulated a large amount of data,such as operation,maintenance and test data,it needs to look at the data analysis of equipment failure data,so as to provide parameters for PSA analysis,and provide guidance for nuclear power plant equipment maintenance. This paper introduces the process of failure analysis,statistical analysis on the failure data,and points out the problems encountered in the process of failure analysis and Suggestions.
