摘要: 为验证设备的稳定性、可靠性以及在极端条件下的安全功能,在地震模拟振动台上,采用一组控制棒驱动线实物作为足尺模型,进行了控制棒驱动线的抗震试验研究。得到了不同的地震输入对控制棒驱动线落棒时间的影响;测量了运行安全地震(SL-1)、极限安全地震(SL-2)水平下,控制棒驱动线的加速度响应值和应变值;验证了不同工况下控制棒驱动线的安全功能。试验数据表明,该驱动线在运行基准地震(OBE)、安全停堆地震(SSE)工况下,均能保持结构的完整性,并能实现运行功能。

Abstract: To verify the stability,reliability and security function in extreme conditions,the anti-seismic test of control rod drive line was conducted.Drop-time of control rod drive line in different earthquake intensities was got.The response and strain values of control rod drive line acceleration on SL-1,SL-2 level were measured.Safety functions of control rod drive line were validated in different work conditions.Anti-seismic test data shows that the driving system can keep the structure’s integrality and realize operation function under OBE and SSE.
