| 摘 要： | 对百万千瓦级核电厂的停堆运行事故风险进行内部事件1级概率安全评价(PSA),并根据不同的停堆进程分别建立停堆PSA模型,分析经历LOI-RRA水位对电厂风险水平构成的影响。分析结果表明停堆工况下的电厂风险不可忽视,在冷停堆工况下经历LOI-RRA水位导致堆芯损坏频率明显增加。

| Abstract: | This paper initiates a study focused on shutdown safety as well as Probability Safety Analysis（PSA） for shutdown operation at 1000 MW PWR.Shutdown PSA models considering different plant outage types are constructed respectively to evaluate the risk of LOI-RRA operation.The results show that the potential risk during shutdown should not be ignored;going through the LOI-RRA operation at cool shutdown refueling outage significantly increases the plant risk. |
