Résumé

The "Fission Products (FPs)" experimental programme was carried out from 1998 to 2004 in CEA/Valduc Apparatus B in the framework of the IRSN-AREVA NC Common Interest Program dealing with "burnup credit" studies. It aims at compensating for the lack of critical experiments with FPs in the literature and validating a selection of 6 stable, non-volatile, fission products representing half of the irradiated fuel absorption of all fission products: 103Rh, 133Cs, 143Nd, 149Sm, 152Sm and 155Gd. This paper provides a more exhaustive approach of the keff results, uncertainties and tendencies associated with the different steps of the "Fission Products" programme.
