摘要：为验证某核电站应急柴油发电机组辅助用高温水循环泵的抗震性能，根据国家相关规范标准进行了抗震性能试验研究。采用白噪声信号作为输入激励，分别测试了高温水循环泵在抗震试验前后的固有频率和阻尼比：根据高温水循环泵具体位置选定对应的反应谱，进行了5次运行基准地震试验和1次安全停堆地震试验。试验结果表明：该型高温水循环泵有足够的抗震强度，能够在规定的地震条件下正常运行，满足抗震性能要求。

Power System Engineering Company, Shaanxi Diesel Heavy Industry Co., Ltd., Shaanxi Xian 710077) Abstract: According to the relevant national standards, seismic test was carried out to verify the perfor mance of auxiliary high temperature water circulating pump for emergency diesel generator set in one nu-clear power station. The natural frequency and damping ratio of high temperature water circulating pump has been measured using white noise signal as input excitation. According to the specific position of the high temperature water circulating pump, the corresponding earthquake response spectrum was selected, and 5 times of operation basis earthquake tests and 1 time of safe shutdown earthquake test were carried out. The results show that the high temperature water circulation pump has enough anti-seismic intensity, and able to run normally under the conditions of prescribed seismic conditions, thus could meet the seis-mic requirements.

0引言
地震情况下，核电站的内部电源有可能发生断
电故障，此时反应堆堆芯内产生的大量热量如果得不到及时有效的冷却，将可能导致堆芯融化甚至爆炸，后果极其严重。因此在核电站的设计中必须要
