In the conventional analysis in the sodium-cooled fast reactor (SFR) plant design, the physical phenomena occurring in each part of the plant are evaluated individually and the interaction between the phenomena is considered under conservative boundary conditions. Therefore, it can be a conservative evaluation in viewpoint of the total balance in the plant design. In this investigation, the integrated platform wchich can couple the detailed analysis codes with the plant dynamics analysis code in order to consider the interaction between the phenomena has been developed as a support tool for achieving optimized design of the SFR plant. In this report, outlines of the development purpose of the integrated platform, the coupling method of analysis codes, and the future development is described.
