摘要
本文结合 650 MW两环路压水堆核电厂发生中破口失水事故的特点、系统参数变化、事故进程以及运行人员的干预对事故发展的影响,运用PSA事件树分析方法对 650 MW压水堆核电厂中破口失水事故事件序列进行分析和评价.通过建立事件树模型,计算 650 MW压水堆核电厂发生一回路中破口失水事故后堆芯损伤的概率,为评价电厂的安全运行提供指导性建议.
Abstract
This thesis analyzed and evaluated the medium LOCA accident of 650 MW PWR with the PSA event tree method to get the consequences and accident sequences.The influence of the characteristics of the medium LOCA,the variation of plant parameters,and the reaction of plant staff on the event development were consid-ered.Through the establishment of the event tree model,the probability of core damage after the LOCA in the primary circuit of 650 MWe PWR nuclear power plant is calculated,which provides instructive suggestions for e-valuating the safe operation of the power plant.
