简要介绍了强震动观测和地震预警技术及其核电站工程中的应用情况。基于有关导则相关要求的介绍，对核电站强震观测系统的一般要求进行了说明，分别以Beznau核电站和我国某核电站为例，介绍了强震仪测点的布置情况。以立陶宛 Ignalina 核电站为例，对地震预警技术在核电站中的应用情况做了分析和探讨。最后，提出了今后核电站地震观测和地震预警中值得关注的有关问题。

This paper introduces the application of strong earthquake monitoring and earthquake early warning in nuclear power plants. Based on RG1.12 and HAD102-02, the requirements of earthquake monitoring are compared, the monitoring systems of Beznau NPP and a NPP in China are illustrated. The earthquake early warning system for Ignalina NPP is introduced, which is the first NPP with such a system.Fninallly, some detail questions are discussed about strong earthquake monitoring & earthquake early warning in nuclear power plants.
