Japan Atomic Energy Agency and Central Research Institute of Electric Power Industry have been conducting a project to develop safety analysis methodologies on metal fuel sodium-cooled fast reactors in the area of advanced reactors under the framework of the U.S.-Japan bilateral commission on civil nuclear cooperation since 2018. The project encompasses analysis methodology development and experiment on core bowing reactivity analysis, core damage accident analysis, and mechanistic source-term analysis. This report describes the project overview and the outcomes of five-year activities in Phase 1: 2018-2022.
