摘　　要：压水堆核电站堆内构件振动监测系统(Vibration monitoring system,VMS)通过分析堆外中子噪声信号,实现堆内构件振动情况的监测。在对中子噪声信号进行分析时,发现中子噪声信号出现了严重削波和电平异常问题。建议对信号通道进行排查检修,彻底解决中子噪声信号异常问题,为核电站的安全可靠运行提供保障。Through the analysis of ex-core neutron noise signal by Vibration monitoring system, the monitoring of vibration condition of the reactor internals was realized. The serious signal clipping and abnormal level problems was found in the analysis of neutron noise signal. To completely solve the problems of neutron noise signal and provide guarantee for safe and reliable operation of nuclear power plant, the signal channel is recommended for troubleshooting and maintenance.
