Seismic safety analysis of rear slope of prototype fast breeder reactor "Monju"

Ito, Kei; Ohshima, Hiroyuki

In accordance with the revision of "Regulatory guide for seismic design of nuclear power plants", Japan Atomic Energy Agency evaluated the seismic safety of the prototype fast breeder reactor "Monju" based on the revised guide. In this study, the seismic safety of the rear slope was analyzed by mechanistic simulation methods. In the distinct element method simulations, the seismic safety was evaluated in the simulation cases of various seismic wave amplitudes. As a result, the design earthquake ground motion did not cause any collapse (landslide) on the rear slope. In the moving particle semi-implicit simulations, the simulation results showed that the movements of the surface layer is at most several tem meters and therefore, the rocks in the rear slope could not attack the "Monju" plant. In conclusion, the mechanistic simulations showed that the rear slope of "Monju" had a sufficient seismic safety for the design earthquake ground motion.
