CENTER高通量工程试验堆功率调节及启停操作较为频繁,控制棒驱动线设计时需重点考虑停堆控制棒落棒缓冲效果以保证寿期内使用的可靠性。对6种缓冲结构进行缓冲试验,根据落棒冲击力及落棒时间等关键因素对比选型,确定最合适的缓冲结构。选定结构下的控制棒驱动线落棒时间合适,落棒冲击力不大,适合用于CENTER高通量工程试验堆。
CENTER high-throughput test reactor power adjustment and start-stop operation is more frequent, the control rod drive line design should focus on stopping control rod drop stick buffer effect to ensure the reliability of life. Six types of buffer structures were tested for cushioning, and the most appropriate buffer structure was determined according to the key factors such as falling impact and falling time. The control rod drive line under the selected structure is suitable for falling time of falling rod and small impact force of dropping rod, and is suitable for the CENTER high-throughput engineering test reactor.
