摘　　要：以预期瞬态不停堆系统为研究对象,根据信号类型的不同,设计了3种不同的定期试验方案.给出了基于马尔可夫模型对各组合结构可靠性的定量分析方法.分别计算了3种类型模块组合结构的拒动率,得出了拒动率随定期试验周期的延长而增大的结果,根据系统可靠性的设计需求,确定定期试验周期,为定期试验周期的确定提供依据.This paper takes anticipated transient without scram system as the research object.Three different schemes of periodic test are designed according to the different signal types.A quantitative analysis method based on Markov model for the reliability of the combined structures is presented.The rejection probability of three types of modular composite structures are calculated,and the results show that the rejection probability increase with the increase of the periodic test period.The periodic test period should be determined according to the design requirements of system reliability,which provides the basis for the determination of the periodic test period.
