【摘要】 介绍了近期美国、日本和中国核电厂抗震设计地震动规范的现状和趋势,以上海核工程研究设计院开展的AP1000机型核岛基础隔震设计课题为例,分析了AP1000机型核岛基础隔震设计的必要性及总体概念设计内容,研究了美国核管会目前重点关注的核岛基础隔震设计内容以及上海核工程研究设计院的应对策略,研究成果为核电厂的抗震设计及核岛结构基础的隔震设计提供了重要的参考依据。更多还原

【Abstract】 Current situation and developing trends of the seismic input of nuclear power plant are firstly introduced and analysed in U. S. A.,Japan and China. Taking the seismic-isolated foundation project of nuclear island as the example in Shanghai Nuclear Engineering Research & Design Institute,the article mainly focuses on the necessity research and general concept design of nuclear island seismic-isolated foundation for AP1000 units. Then the main content of seismic-isolated foundation from U. S. Nuclear Regulatory Commission and countermeasures from Shanghai Nuclear Engineering Research & Design Institute are researched. This work provides some guidance for further study on seismic input of nuclear power plant and seismic-isolated foundation of nuclear island as a reference.更多还原
