Development of Advanced Reactor Knowledge- and Artificial Intelligence (AI)-aided Design Integration Approach through the whole plant lifecycle (ARKADIA) has been started in Japan Atomic Energy Agency. ARKADIA can automatically provide possible solutions of design, safety measures, and a maintenance program to optimize the lifecycle performance of advanced reactors by using the state-of-the-art numerical simulation technologies. In the first phase of this project, ARKADIA-Safety is developed for the purpose of automatic optimization of the severe accident (SA) management and its feedback to the plant design of sodium-cooled fast reactors (SFRs). This paper describes the overview of ARKADIA-Safety and its application for SA evaluation.
