快堆停堆后，热池中的冷却剂从强迫流动转化为自然循环流动，通过自然循环方式导出堆芯的衰变热。在自然循环条件下，热池内结构布置对热工水力特性具有很大影响。在所有影响自然循环的热池结构布置因素中，余热冷却器的位置变化十分突出。为了给快堆热池内的结构布置设计提供
After the fast reactor is shut down, the coolant in the hot pool transforms from forced flow to natural circulation flow, and the decay heat of the core is derived through natural circulation. Under natural circulation conditions, the thermal pool structure has a great influence on the thermal-hydraulic characteristics. In all thermal pool structure affecting the natural circulation of the layout factors, the position of the waste heat cooler is very prominent. In order to provide fast thermal reactor structure design layout
