<p>In the seismic evaluation of buildings and structures in nuclear facilities, lumped mass models have been used conventionally. In order to perform seismic evaluation of nuclear facilities with higher accuracy, it is necessary to evaluate the input wave to the equipment in the facility more precisely, considering the local response of the reactor building. In this point of view, a seismic response analysis method using a three dimensional finite element (3D FE) model, which is expected to evaluate the local response of the reactor building, is currently being developed. In addition, since the 3D FE model has a problem that the analysis results have large uncertainty depending on the analyst, it is important to ensure the reliability of analysis results by developing a standard analysis method. In Japan Atomic Energy Agency (JAEA), we have developed a guideline for seismic response analysis method using 3D FE model of reactor building. The guideline consists of a main body, explanation, and several supplements and includes procedures, recommendations, points of attention, and technical basis for conducting seismic response analysis using a 3D FE model of reactor building. In this paper, the outline of the guideline and analysis examples based on the guideline are presented.</p>

2021 28th International Conference on Nuclear Engineering (ICONE28)

Supporting the need among researchers worldwide for additional online and multimedia content, ASME now offers the ASME Conference Video Collection. This platform will collect and provide long-term access to conference presentation videos, encompassing all technology areas within ASME's technical conference and events program. About 30,000-40,000 engineers across all mechanical engineering and related disciplines participate in ASME conferences each year. This includes authors of approximately 6,000 to 8,000 technical papers published by ASME, the majority of whom also submit video presentations for our virtual conferences. The video collection will be available as an add-on to existing product packages or as a separate subscription.
