A lot of papers about the report of probabilistic risk assessment of daya bay npp and system manuals has been read by the author and let as the basis. in this paper, based on the reliability analysis methods of failure mode and effect analysis and failure tree analysis, according to the result of event tree analysis of probabilistic risk assessment report of daya bay npp, the top events of the fault trees of reactor protection system and the success criteria were established. by using risk - spectrum procedure, the unavailability and the minimal cut - sets ( mcs ) of the fault trees were obtained
本文在閱讀了大量的大亞灣核電站pra報告和各種系統手冊等資料的基礎上，採用fmea （故障模式和影響分析）和fta （故障樹分析）可靠性分析方法，依據大亞灣核電站pra事件樹分析的結果，建立了以緊急停堆失效和專設安全設施驅動失效為頂事件的故障樹，利用risk - spectrum程序，對所建的故障樹進行定量分析，計算，得到系統故障樹的失效概率和最小割集，從而為大亞灣核電站可視化風險分析軟體提供數據支持。 -
The reactor protection system reliability analysis of daya bay npp is an important branch of the probabilistic risk assessment project of daya bay nuclear power plant. the purpose of probabilistic risk assessment of reducing reactor trip is to discover all the signals and the components which can result in reactor trip potentially, to assess the safety and reliability of systematic design, to find the potential design drawbacks and take effective measures to reduce such events
