Abstract
FRAM and MGA++ are software codes used worldwide to measure the isotopic abundances of uranium and plutonium. New versions of these codes (FRAM V5.1 and MGA++ v1.1) were evaluated in the framework of a DOE/NNSA and IRSN cooperation. The following method was proposed for the evaluation of such codes: selection of a reference data set of spectra (uranium, plutonium or MOX), that will cover as many situations as possible; analysis of this data set using the different versions of FRAM and MGA++; study of global indicators to compare these different versions. Results based on this method are presented for FRAM and MGA++.
