【摘要】：[目的]为研究二回路非能动余热排出系统(PRHRS)的运行特性,[方法]借助瞬态热工安全分析程序RELAP5,建立主冷却剂系统和二回路非能动余热排出系统的仿真模型。对二回路非能动余热排出系统的3个关键设计要素(设计负荷、应急补水箱及蒸汽侧隔离阀开启速度)开展全部电源丧失事故及单侧主给水管道断裂事故工况下的瞬态计算和对比分析,[结果]分析结果表明:设计负荷需综合考虑系统安全性与冷却速率;应急补水箱向蒸汽发生器注水有利于事故后的初期冷却,而降低隔离阀开启速度可改善系统的启动特性。[结论]计算分析结果可为核动力装置二回路非能动余热排出系统设计提供参考。
[Abstract]:[objective] in order to study the operation characteristics of the secondary loop passive residual heat removal system (PRHRSs), [methods] the simulation models of the main coolant system and the secondary loop inactive residual heat removal system were established by the transient thermal safety analysis program RELAP5. Three key design elements (design load) of the secondary loop inactive residual heat discharge system are discussed. The transient calculation and comparative analysis of all power loss accidents and single side main water supply pipeline breakage accidents are carried out. The results show that the design load should be integrated. Considering system security and cooling rate; The injection of emergency water tank into the steam generator is beneficial to the initial cooling after the accident, while reducing the opening speed of the isolation valve can improve the startup characteristics of the system. [conclusion] the results of calculation and analysis can provide reference for the design of passive residual heat discharge system in secondary loop of nuclear power plant.
