Summary

After recalling the various planned experiment types, this paper describes the status of the joint irsn/COGEMA progressive qualifying experimental programme on 6 major selected Fission Products (FPs), 103 Rh, 133 Cs, 143 Nd, 149 Sm, 152 Sm & 155 Gd, as part of their joint Burn Up Credit (BUC) studies, which now includes 95 Mo. For the so-called ‘Physical Type’ experiments now completed and evaluated, the paper presents some sample results obtained on the exact and fine modelization such as: keff with the standard irsn calculation route, FPs ntireactivity weight, cross section comparison, energy zone of FPs qualification. It especially gives the calculation details related to the reactivity weights of the various experimentals uncertainties attached to these experiments. This work has been done with COGEMA's collaboration
