In advanced reactors where components inside the reactor vessel are subjected to high thermal environment, thin-walled designs are generally preferred in order to minimize stresses induced by temperature. Thin-walled structures, however, have little inherent resistance to seismic loadings. It is therefore not an easy task to design such components that will resist thermal and seismic loads simultaneously. Recently seismic isolation has increasingly been applied to nuclear as well as non-nuclear structures as an efficient and economic engineering solution to mitigate seismic hazards. With seismic isolation, safety margins of both the isolated structure and its contents are enhanced. This paper presents the isolated and unisolated responses of two liquid metal reactor plants to earthquake time-histories. Different isolation systems have been considered in this investigation.
