基于GO-FLOW-Markov法的核电站给水系统可靠性分析
Reliability analysis of nuclear power plant feedwater system based on GO-FLOW-Markov method
摘要
Abstract
When the GO-FLOW methodology is used to analyze the reliability of the nuclear power plant feedwater system,there is a problem that the parallel standby subsystem in the system cannot be handled.Therefore,a reliability analysis method based on GO-FLOW-Markov is proposed to solve the system reliability by establishing the Markov state transfer matrices of the primary and standby systems,and using this method as an arithmetic rule,a new operator with universal applicability,the standby gate,is proposed to extend the GO-FLOW methodology operator.Considering the existence of multiple redundant systems,the reliability analysis model of feedwater system with common cause failure is established and calculated by introducing the α factor.The results show that the GO-FLOW-Markov method can be used to calculate the reliability of parallel standby system,and the factors considered are more comprehensive than the conventional GO-FLOW methodology.The common cause failure of nuclear power plant feedwater system has obvious influence on the system reliability,so the common cause failure problem should be considered for the complex system,and the reliability calculation results are more suitable for the engineering practice.关键词
