Seismic Response of High Temperature Gas-Cooled Reactor Core with Block-Typed Fuel, (V)

Analytical Method of Seismic Response for Two-Dimensional Horizontal Slice Core Model

抄録

An analytical method for the seismic response of the two-dimensional horizontal slice core model of a high temperature gas-cooled reactor core with block-type fuel has been developed. In the analytical method, blocks are modeled as rigid bodies and a spring dashpot model is used for the collision process between blocks. Analytical results are compared with experimental ones and both are found to be in good agreement. The analytical method can be used to predict the behavior of the high temperature gas-cooled reactor core under seismic excitation.
