摘　　要：以大亚湾核电站辅助给水系统为研究对象,应用GO-FLOW法计算分析了该系统不同阶段的可靠性。根据系统原理图直接构建了系统GO-FLOW模型,利用GO-FLOW程序计算系统在不同时刻的可靠度。结果表明,GO-FLOW法是一种有效、直观、精确的可靠性分析方法,可以为核电站动态可靠性分析提供依据。The GO-FLOW methodology has been applied to a reliability analysis of Auxiliary Feed Water Sys- tem （AFWS） of Daya Bay nuclear power plant as an example which is time-related issue and has a complex operational behavior. In this paper, GO-FLOW chart was drawn according to the principle chart of AFWS, and the success probabilities of AFWS at different time points were calculated. The analysis results well explain that GO-FLOW could be well applicable to the analysis of PWR-AFWS, GO-FLOW has proved to be an effec- tive and useful methodology in system reliability analysis, and it can provide technology support to the living risk monitoring system.
