摘　　要：针对核电站非能动系统硬件失效较少、物理过程失效较多的特点,基于非能动系统的定义和主要特性,对其可靠性进行了分析。以非能动余热排出系统和安全壳冷却系统为例,通过对不同非能动系统可靠性分析方法的比较,指出了各种方法的特点和适用情况。由于实际运行数据缺乏,数学方法的引入对非能动可靠性分析具有重要价值。Aiming at the fault feature of the nuclear power station,which is that there the hardware failure of the passive system is infrequent and the failure of the physical process occurs more often,based on the definition of the passive system and its main features,the reliability of the passive system was analyzed.Taking the passive residual heat removal system and the containment vessel cooling system as examples,the reliability analysis methods for different passive systems were compared,and the features and the applicability of each method were pointed out.Due to the lack of practical operation data,introduction of the mathematic method is of important significance for reliability analysis of passive system.
