From high-efficient to high-accurate analyses for the operating status including normal, abnormal transient and accident in sodium-cooled fast reactor will be conducted in a single simulation system by employing multi-level models. The system will be able to respond flexibly to the design option of the reactor. The conceptual design of the new system, the coupling method of codes as a key of the system development, and the development plan are reported.
