摘　　要：通过对AP1000核电机组二回路低压加热器(简称低加)疏水系统的研究,提出了11种不同的疏水布置方案,并通过EBSILON平台进行仿真计算,对不同疏水方案下机组的热经济性进行比较、分析。综合考虑系统热经济性及安全性,认为优选在3号低加设置疏水泵的方案,供电热耗可降低33. 33kJ/(k W·h)。Through the research of the low pressure heater drain system in the secondary circuit of AP1000nuclear power unit,11different arrangement schemes are proposed.Through the EBSILON platform,the simulation and calculation are carried out to compare and analyze the thermal economy of units under different schemes.Considering the system thermal economy and safety,it is considered preferable to set a drain pump at No.3low pressure heater with a reduction of33.33kJ/(kW·h)in heating energy consumption.
