摘要 介绍了非能动设计在压水堆核电机组二回路余热导出方面的工程应用。以我国自主研发的在建堆型"华龙一号"中的二回路非能动余热排出系统(PRS)为研究对象,介绍了系统的设备组成、机组在不同运行条件下PRS系统的运行模式。对PRS系统投运后从热源和热阱两方面对系统运行特性进行定性分析。分析了系统自动控制逻辑中主要因素的不同触发现象对P R S系统投运的影响,并根据分析结果对系统控制逻辑提出了改进建议。 This thesis mainly introduces the engineering application of the passive design in the residual heat removal of the secondary side in nuclear power plant.In this thesis,the passive residual heat removal system of the secondary loop(PRS)is studied,which was applied in the advanced PWR-HPR1000(Hualong One)independently developed by China.Additionally?components and the operating mode of PRS under different operating conditions are introduced.This thesis also makes a qualitative analysis for the characteristics of the heat source and heat sink after PRS is placed in service.The influence of different triggering phenomena,caused by the automatic control logic of the PRS system,on the automatic operation of the PRS system is analyzed.In the end,some suggestions on the automatic control logic of the PRS system are put forward based on the analysis results.
