摘　　要：为研究浮动核电站凝汽器的动态工作特性,建立了凝汽器相变仿真模型,并进行了稳态计算结果验证和瞬态仿真分析。计算结果表明:稳态计算结果与试验结果的偏差较小,该模型能够满足凝汽器热力性能计算要求;在海水温度出现变化时,凝水温度和凝汽器压力的动态响应速度较快,凝汽器负荷产生显著变化;循环水断流后,凝汽器压力急剧升高,3s内即可达到凝汽器报警压力。In order to study the dynamic working characteristics of the condenser of floating nuclear power plant,a phase-change model of the condenser is established,and the steady-state calculation results and transient simulation analysis are carried out.The calculation results show that the deviation between the steady state calculation result and the experimental data is small,and the model can meet the calculation requirements of the condenser thermal performance.When the seawater temperature is disturbed,the dynamic response speed of the condensate temperature and the condenser pressure is fast,and the condenser load changes significantly.The pressure of condenser increase rapidly after cutoff of the circulating cooling water,and the alarm pressure of the condenser is reached within 3s.
