摘　　要：为验证国产第三代压水堆ACP1000控制棒驱动线(CRDL)在三代核电要求地震条件下的结构完整性和功能完好性,在多点激励试验装置上,采用一组控制棒驱动线1:1样机作为试验对象,进行CRDL的抗震试验研究。试验中采用多频波法进行CRDL水平和竖直2个方向的地震激励,得到地震对CRDL落棒时间的影响;测量了运行基准地震(OBE)和安全停堆地震(SSE)下CRDL的加速度响应值和应变值,验证了CRDL在OBE下的运行功能和SSE下的安全功能。试验结果表明:ACP1000的CRDL在地震载荷作用下能够保持其结构完整性和功能完好性。To verify the structural integrity and operability under the seismic condition required by the third generation of nuclear power plants, the seismic test of ACP1000 control rod drive line （CRDL） was conducted on the multi-exciters test unit. One horizontal direction and one vertical direction of the CRDL were excited with multi-frequency earthquake time history. Drop-time of CRDL under earthquake was obtained. The acceleration and strain response values of CRDL under OBE and SSE level were measured. Operation functions under OBE level and safety function under SSE level of CRDL were validated. The seismic test shows that ACP1000 CRDL can keep the structural integrity and operability under the seismic condition.
