This study develops assessment methods necessary to obtain a long-term structural integrity outlook for reactor buildings that suffered from the 2011 Great East Japan Earthquake disaster in which access to the site was extremely limited due to high radiation dose rates and high contamination. It is one of the "Nuclear science and technology and human resource development promotion projects" implemented by the Japan Atomic Energy Agency (JAEA) International Collaborative Research Center for Decommissioning and Environment (CLADS) in FY2021 to 2023. This paper introduces an outline and overview of the project.
