Research and development of three-dimensional vibration simulation technologies for nuclear facilities is one mission of the Japan Atomic Energy Agency (JAEA). In this paper, we report a seismic response analysis of the 2011 off the Pacific coast of Tohoku Earthquake using three-dimensional models of the High-Temperature Engineering Test Reactor (HTTR) building. We performed a parametric study by using uncertainty parameters. Furthermore, we examined the variation in the response result for the uncertainty parameters to create a valid 3D finite element model.
