摘　　要：利用流体力学软件CFX对中国实验快堆(CEFR)整体冷钠池及其辅助系统进行详细稳态模拟计算,并验证运行工况下的热工设计。计算结果表明:冷钠池内存在热分层和热分区现象,确实存在冷钠池上板的高温区,同时泵腔室上部的温度较其他区域的高。本工作为反应堆功率提升及运行提供了技术准备。Using code CFX,the integrative cold sodium pool and auxiliary system of CEFR was calculated at steady state case and the thermal design was verified at operation case.The results show that there are thermal stratification phenomena in the cold sodium pool,there exists really the high temperature region at the upper board of the cold sodium pool,and the temperature in the upper zone of bump inhaling plenum is higher than that of other regions.The results provide technical preparation for power up and operation of CEFR.
