摘　　要：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。The research reactor CENTER HFETR is with frequent start-up, shut-down and power follow-up, and the designing of the CRDM should focus on the buffering effect to ensure its reliability during its life time. Buffering tests are conducted on six models, and the buffer structure is selected based on the comparison of the control rod dropping impact and dropping time in the condition of static and dynamic water. The selected structure is with proper dropping time and small impact, which is applicable for this research reactor.
