摘　　要：乏组件转换桶及其冷却系统,用于对临时存放的乏组件剩余释热的冷却,桶中的钠温需稳定地保持在一定范围内。本文通过热工流体力学的理论计算,获取了正常换料工况下乏组件转换桶中的组件释热函数,根据该释热函数,提出了一种与之匹配的冷却控制方案,使得乏组件转换桶中的温度能够恒定地运行在250℃±5℃。The spent fuel assembly transfer bucket and its cooling system are used for cooling the remaining heat release of the temporarily stored spent assembly,and the sodium temperature in the bucket needs to be stably maintained within a certain range.Based on the theoretical calculation of thermal fluid mechanics,the heat release function of the component in the fuel assembly transfer bucket under normal refueling conditions is obtained.Based on the heat release function,a kind of matching cooling control scheme is proposed to make the temperature in the transfer bucket can be constantly operated at 250℃±5℃.
