*KOJI NISHIDA1, Toshihide Torige1, Naoki Sano1, Takayoshi Kusunoki1, Michio Murase1 (1. Institute of Nuclear Safety System, Inc.)

Keywords:Severe accident, Fuel damage, Fuel relocation, Porosity

In order to examine fuel damage, relocation and porosity on SFD 1-4 test, the mock-up fuel temperatures were evaluated by MAAP5. In the analysis, the initial temperatures on the outer surface of insulator were adjusted to the measured data. It was confirmed that the predicted clad temperatures were in good agreement with the measured data.
