摘　　要：CENTER高通量工程试验堆控制棒驱动线考虑到压力容器底部的安装空间紧张采用错层布置方式,需要开展抽插阻力测试、控制棒驱动线落棒试验进行对比,了解错对中值对两种不同布置高度的控制棒驱动线的运行及落棒性能影响,为驱动线的设计定型和安全评定提供必须试验依据。试验结果表明,错对中值增大对不同布置高度的控制棒驱动线落棒性能及抽插阻力的影响趋势是一致的,但在相同错对中值条件下布置于相对低位的长管座型驱动线上下运行所受抽插阻力相对更小,落棒时间更快、落棒冲击力更大。The CRDM need to be split-level installed,because the installation space for the CRDM of center reactor is limited.There is necessary to do the running tests and rod drop tests for the different eccentricity.From that we can get the impact of eccentricity on the split-level CRDM and provide experimental evidence for the design and safety assessment of CRDM.The test results show that the impact of eccentric on the split-level CRDM is consistent,but the long tube support CRDM has a lower running.
