In Japan Atomic Energy Agency, a design optimization support tool named ARKADIA-Design is being developed for advanced nuclear power plant system including sodium-cooled fast reactor (SFR). Achievements in the development of optimization processes in the fields of the core design, the plant structure design, and the maintenance schedule planning, as major function of ARKADIA-Design, are summarized at this point in time and challenges for further development in the next step are discussed.
