Keywords:SAMPSON, MCCI, Fukushima Daiichi accident

A sensitivity analysis of the severe accident of Fukushima Daiichi Unit 1 is performed by means of CVPA and DSA-1 modules of SAMPSON code. The study intends to evaluate a final relocation of the fuel debris and estimate the concrete ablation in the pedestal and drywell environments of the Pressure Containment Vessel.
