Résumé

The "Fission Products (FPs)" experimental programme dealing with "burnup credit" studies was carried out from 1998 to 2004 in CEA/Valduc Apparatus B with the support of AREVA NC company. 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, namely 103Rh, 133Cs, 143Nd, 149Sm, 152Sm and 155Gd, representing half absorption of all Fission Products in irradiated fuel. This paper provides a more exhaustive approach of the solution preparation and of the different studies performed regarding the experimental uncertainties associated with the different steps of the "Fission Products" programme.
