Analysis and Calculation of the Power-unrecovery Factor in the Event Tree of Loss of Offsite Power

Institute of Nuclear Energy Technology, Tsinghua University, Beijing, 100084, China

摘要: 在核电站中,丧失外电源是较为常见的始发事件,丧失外电源事件树中必须考虑电源恢复对各事故序列发生频率的影响。本文通过大亚湾核电站的实例分析,说明在丧失外电源事件树上各种前沿系统电源不可恢复因子计算的方法。

Abstract: Loss of offsite power is an initiating event that takes place often in the nuclear power plant. The effect of power recovery on the frequency of each sequence shall be taken into account in the event tree of loss of offsite power. In this paper, the method of calculating the unrecovery factors of different frontier systems is discussed.
