The spent fuel rack of a nuclear plant stores the spent fuel temporarily before it can be moved to a reprocessing facility. Therefore, the spent fuel rack must have a high tolerance against big seismic loads. So, the free standing rack is developed in Japan as other countries. To develop an analysis evaluation method for the free standing rack motions, we carried out seismic experiment of the full-scale free standing rack to obtain the fundamental data about it. The free standing rack motions are sliding and rocking under seismic excitation. To evaluate the sliding and rocking motions of the free standing rack, we reflected test result to analysis method, and developed the dynamic response analysis model.
