Seismic Testing of the Base-Isolated PWR Spent-Fuel Storage Rack

Abstract

The present paper aims to verify the seismic safety of the base-isolated spent-fuel storage rack. A series of seismic tests has been conducted using a three-dimensional shaking table. A sliding-type base-isolation system was employed for the prototype rack considering environmental conditions in an actual plant. A non linear seismic response analysis was also performed, and it is verified that the prototype of a base-isolated spent-fuel storage rack has a sufticient seismic safety margin for design seismic conditions from the viewpoint of seismic response.
