| 摘 要： | 在研究故障模式、影响及危害性分析法(FMECA)、故障树分析法(FTA)特点的基础上,通过FMECA与FTA之间的相互关系,提出了一种用于核级先导式安全阀故障分析的正向FTF分析方法。该方法既考虑了产品中每个功能故障模式及影响,又考虑了硬件、软件、人为和环境等因素以及多重故障的综合影响。利用该方法对安全阀的故障进行了定性分析,确定了安全阀系统的重要故障模式和可能引发安全阀重要故障的关键零部件。

| Abstract: | On the basis of studying the characteristics of Failure Modes, Effect and Criticality Analysis (FMECA) method and Fault Tree Analysis(FTA) method, a forward FTF method which integrates FMECA with FTA is built to analyze the failure of the nuclear Pilot-Operated Safety Valve. It is a comprehensive and exhaustive method which has considered the integrative effect caused by every function failure mode, hardware, software, artificial factor, environment and multiple failure modes. Through the qualitative analysis of the valve failure mode with the method, the most important failure modes of the valve system and important parts are found. A feasible method for failure analysis of the valve system is provided in this paper. |
