基于故障树分析法的核电厂氢气系统爆炸危害性分析

The Analysis of Hydrogen System Explosion Risk in NPP Based on FTA

本文针对在核电厂内广泛使用的氢气系统可能引发爆炸事故的实际情况,利用故障树分析法,对可能导致氢气爆炸的各种因素及逻辑关系进行了全面、简洁和形象的描述,查明了系统内固有的或潜在的各种危险、有害因素,并分析总结了导致氢气爆炸的主要根本原因,提出了针对这些基本原因改善系统安全性的建议,为核电厂氢气系统的安全相关设计、施工和管理提供了理论支持.

For the widespread use of hydrogen system in the nuclear power plant, through using the Fault Tree Analysis, this article describes the various factors and logical relationship that may cause the hydrogen explosion accident, finds out the eonnatural or potential risk and harmful factors in the system, analyzes and summarizes the ultimate reasons that cause the hydrogen explosion accident, gives some suggestions to improve the safety func- tion of the system, provides the theory support for the safety related design, construction and management of hydrogen system in the nuclear power plant.
