田湾核电厂数字化反应堆保护系统故障模式与后果分析

Failure Mode and Effect Analysis for Digital Reactor Protection System in Tianwan Nuclear Power Plant

摘要: 从田湾核电厂数字化反应堆保护系统的结构出发，对数字化保护系统可能出现的故障种类、影响区域和故障后果等进行了详细分析, 通过故障模式与后果分析（FMEA）方法，对田湾核电厂数字化反应堆保护系统是否存在设计薄弱环节作出了判断。本工作为国内数字化反应堆保护系统设计提供了一些新思路。

Abstract: The paper describes the structure of digital reactor protection system in Tianwan Nuclear Power Plant, and gives the analysis of the failure mode, effect area and the measure against failure. According to the analysis, the paper evaluates the reliability of digital reactor protection system. At the same time, the paper supplies some new idea for the design of digital reactor protection system.
