摘　　要：以美国10 MW熔盐实验堆(MSRE)为研究对象,设计空气冷却和水冷却2种非能动余热排出系统。通过建立相应的数学模型,采用C++语言编程,分别对系统的主要特性进行研究,并对2种系统的运行特性进行比较分析。结果表明,虽然空气冷却和水冷却均能满足系统的排热要求,并能形成稳定的自然循环,但从长期冷却性能方面看,空气冷却方案的综合性能更好。The water-cooled and air-cooled passive residual heat removal systems （PRHRSs） were designed for 10MW molten salt reactor experiment （MSRE）, according to which the mathematical models were established and numerically solved in the code of C＋＋. Main characteristics of the two systems were given and compared. The results show that both water-cooled and air-cooled PRHRSs can establish stable natural circulations and meet the design requirements for heat removal. However, the air-cooled PRHRS has better comprehensive performance for long term cooling.
