摘要
以故障模式影响分析(FMEA)和FTA可靠性分析方法为基础,依据大亚湾核电站PRA事件树分析的结果,确定了反应堆保护系统(RPR)故障树的顶事件和成功准则,建立了以紧急停堆失效和专设安全设施驱动失效为顶事件的故障树,利用RISK-SPECTRUM程序,对所建的故障树进行定量分析与计算,得到系统故障树的失效概率和最小割集,从而为大亚湾核电站可视化风险分析软件提供数据支持。
Based on the reliability analysis methods of FMEA and FTA, according to the result of ETA of PRA in Daya Bay NPP, the top events of the fault trees of reactor protection system and the success criteria were established. By using RISK-SPECTRUM procedure, the unavailability and the minimal cut-sets(MCS) of the fault trees were obtained. The result of analysis was put into the visual risk analysis software of Daya Bay NPP as the support of data.
