General Consideration for Seismic Input of NPP Seismic Design and Seismic-isolated Research for AP1000 Nuclear Island
-
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.
