Abstract
Research and development on three-dimensional vibration simulation technologies for nuclear facilities is one of the missions of the Center for Computational Science and e-Systems, Japan Atomic Energy Agency. Until now, three-dimensional building and equipment models of High Temperature engineering Test Reactor (HTTR) have been constructed and validated using comparisons with seismic observation records. In this paper, we report the results of a seismic observation simulation of the 2011 off the Pacific coast of Tohoku Earthquake that occurred on 3/11/2011 using three-dimensional models of the HTTR building. The simulation results show good agreement with the observation data.
