(1 The Hangzhou Anti-seismic Office, Hangzhou 310016, China; 2 Dalian Maritime University, Dalian 116026, China; 3 The Hong Kong Polytechnic Uruversity, Hong Kong, China)Abstract: For problems appearing in the earthquake, some suggestions on design and retrofit of nuclear power plants were put forward based on concept design idea. The suggestions involves reasonable layout, multi-channel fortification, strengthening the connection, clear diagram, applying structure control technology and vibration damage detection technology etc.. Some concrete methods were also put forward, such as making containing vessel as a two-layer underground structure, changing the statically detenmnate structure to the statically indeterminate ones, simplifying calculating diagram by dividing structure system, adjusting the mass and stiffness of structure related, strengthening the main structure, weakening subordinate structure, optimizing vibration mode by adjusting the layout to reduce response, applying vibration isolation and damper technology, applying structural damage identification and diagnosis technology, and so on.
