FPT4 is the third test in the PHEBUS program of integral experiments aimed at the study of the release, transport and deposition of fission products in a severe reactor accident. The purpose of the performed ICARE2 calculations is to support a realistic scenario concerning the debris bed thermal behaviour and molten pool formation. The comparison experiment calculation shows a good agreement up to 2200 K. At higher temperature is necessary to assume a steam by-pass through the thermal shroud to reproduce the measured temperatures. With this hypothesis, also the final molten pool configuration is well calculated.
