Since 1993, SAMPSON has been developed as domestic produced code which can perform accident analysis from reactor vessel event to reactor containment event. After the accident at Fukushima Daiichi Nuclear Plant, Institute of Applied Energy improved the model in SAMPSON code and performed the accident analysis which is based on the accident progress and currently continues developing the code. This is continued presentation and we will present control interface for coupled analysis methodology and analysis for validation.
