The PHEBUS Fission Product (FP) program was initiated to understand the phenomena involved in LWR severe accidents and validation of severe accident physical models. The code ICARE2 was developed at IRSN and validation program of this code against several tests has been carried out over the years. In continuation to the validation exercises for further improvement of the code understanding and predictions, a series of sensitivity study has been carried out for FPT0 test. The study has been carried out with an ICARE2 specific reference model. With the understanding gained from this study, a best estimate model has been developed for a better code prediction. The best estimate model predicts well the key parameters and degradation in the upper part is predicted well than the reference model. (authors)
