    VALMOX, an acronym for Validation of Nuclear Data for High Burnup MOX Fuels, is one of the projects of the cluster EVOL (Evolutionary Fuel Concepts : High Burnup and MOX Fuels). It covers 30 months, from October 2001 to March 2004. It considers the evaluation of the actinide inventory of MOX fuel at high burnup (typically 60 GWd/t) in Light Water Reactors, with special attention to the helium production. Calculated values for the spent fuel isotopic masses are compared to the measured ones, with sensitivity analyses made in support. The JEF 2.2 nuclear data file is taken as a basis for calculation. The resulting recommendations on nuclear data should be employed in the preparation and testing of the next JEFF3 file. So far, the major effort was placed on the evaluation of MOX fuel irradiations in Pressurised Water Reactors, and first results will be presented and compared.
