Abstract

A CORE SEISMIC ANALYSIS CODE FINDS FOR PWR AND LMFBR CORE SEISMIC DESIGNS WAS APPLIED TO SIMULATE THE ITALIAN FAST REACTOR PEC CORE SEISMIC EXPERIMENTS. THEMOST EXCITED SEISMIC WAVEVIBRATION CASE WAS CHOSEN FOR THE VALIDATION WORK. THE DISPLACEMENTS AND ACCELERATION RESPONSES OBTAINED BY ANALYSES ANDMEASUREMENTS WERE COMPARED IN DETAIL. THE CLOSE AGREEMENTS BOTH IN DISPLACEMENTS AND ACCELERATIONS IN TIME HISTORICAL DOMAIN APPROVED THAT THE FINDS CODE IS APPLICABLE NOT ONLY TO PWR BUT ALSO TO LMFBR CORE ANALYSES.
