首先简单介绍了世界各国核电厂抗震输入的概况，同时提及了法国、日本及我国相关部门对核岛基础隔震的一些探索，接着重点涉及上海核工程研究设计院针对AP1000系列机组所开展的核岛基础隔震设计课题的总体概念设计内容。本文对核电厂的抗震设计及核岛结构基础的隔震设计提供了较多的实用信息，以供参考。

The article introduces seismic input of nuclear power plant in the world briefly, and mentions some exploratory work for seismic-isolated foundation of nuclear island in France, Japan and China. The article mainly focuses on a general concept design of nuclear island seismic-isolated foundation for AP1000 units by our institute. There are more useful information for seismic input of nuclear power plant & seismic-isolated foundation of nuclear island as a reference.
