摘　　要：本文采用CFD数值模拟分析方法,对快中子反应堆一回路主循环钠泵温度场进行计算,分析钠泵泵盖温度分布规律。结果表明,钠泵的下端温度最高,沿着高度方向向上逐渐降低,整个钠泵结构存在一定的温度下降梯度,泵盖上表面温度没有超过安全准则要求。目前,针对快堆一回路钠泵泵盖传热计算研究尚不足,本次计算分析对此部件设计具有重要的意义。This paper uses CFD numerical simulation analysis method to calculate the temperature field of the sodium circulating pump in the primary loop of the fast neutron reactor,analysis of temperature distribution law of sodium pump cover.The results show that the lower end of the sodium pump has the highest temperature and gradually decreases along the height direction.There is a certain temperature descent gradient in the entire sodium pump structure.The surface temperature of the pump cover does not exceed the safety criterion.At present,there is still not enough research on the heat transfer calculation of the sodium pump cover of the primary loop of the fast reactor.This calculation and analysis is of great significance to the design of this component.
