在多点激励试验装置上,对大型先进压水堆CAP1400控制棒驱动线进行抗震试验研究。试验中采用多频波法在控制棒驱动线2个方向同时地震激励,得到了控制棒驱动线在低水平地震(LLSE)和安全停堆地震(SSE)下的应变值和加速度值。试验结果表明,CAP1400控制棒驱动线在地震载荷作用下能够保持其结构完整性和功能完好性。
In the multi-point excitation test device, the seismic test of large advanced PWR CAP1400 control rod drive line was carried out. The multi-frequency wave method was used to simulate the excitation of the control rod driving line in both directions. The strain and acceleration values of the control rod driving line under low-level seismic (LLSE) and safe-shutdown earthquake (SSE) were obtained. The test results show that the CAP1400 control rod drive line can maintain its structural integrity and functional integrity under earthquake loads.
