We developed the BWR accident progression analysis model for Tokai No. 2 power station by MAAP4. From an analysis result of this model, we obtained a knowledge of plant behavior for mitigation measures in severe accident, consideration to countermeasures of severe accident. In the future, we will use this model to enhance the accident management guidelines and to prepare evidence of the PRA model.
