摘　　要：控制棒组件是核反应堆的重要安全部件,针对小型压水堆中控制棒组件的使用特点,开展了机械与水力一体化缓冲设计,对缓冲器的不同参数组合进行性能分析和落棒缓冲试验,获得了影响其缓冲性能的主要因素及影响规律。结果表明一体化缓冲器可实现有效缓冲,用于小型堆控制棒组件是可行的。基于相关分析和试验结果,对一体化缓冲器用于小型堆控制棒组件的参数设置提出了参考建议。RCCA is one important component to ensure nuclear reactor safety. The mechanical and hydraulic integration buffer for small reactor RCCA is designed according to its application characteristics. Performance analysis and rod dropping tests of the buffer with various parameters combination have been accomplished. Some influence laws of parameters on buffer performance have been obtained. Results show that the integration buffer may provide effectivebuffer for rod dropping and apply to small reactor RCCA. Finally, according the data of analysis and tests,some suggestions on parameters of the buffer for small reactor RCCA are put.
