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.
