In order to apply the FATE code to the severe accident analysis for boiling and drying accident, important phenomena in the accident scenario are extracted based on the PIRT, and evaluation models for these phenomena are built in the FATE code. In addition, based on the fourth report of this series, the validation matrix for each major individual model are developed.
