摘要: 堆容器冷却系统是中国实验快堆(CEFR)一回路系统中的重要辅助系统之一,用于在各种工况下对反应堆堆容器进行冷却。本文利用国际通用的计算流体力学软件STAR-CD对CEFR堆容器冷却系统进行三维数值模拟,得到了在全厂断电事故发展过程中堆容器冷却系统的温度场和流场的瞬态分析结果,为相应部件的力学分析以及其它工况的分析提供了数据,对快堆优化设计和安全分析提供了重要的理论支持。Abstract: Reactor vessel cooling system is one of the important auxiliary systems in the primary system of China experimental fast reactor（CEFR）,which can cool the reactor vessel in various conditions.the reactor cooling system during the station blackout accident.It provides the data for the mechanical analysis,and the theoretical support to the optimum design and safety analysis of the fast reactors.
