Popis: International audience; A new version of the CRISTAL criticality calculation package, named CRISTAL V2.0 [1], has been developed by IRSN and CEA, in collaboration with AREVA. Four calculation routes are now available, using nuclear data issued from the JEFF-3.1.1 evaluation two multigroup routes based on 281 groups cross-sections (APOLLO2 MORET 5 or APOLLO2-Sn calculations), a pointwise Monte Carlo route (TRIPOLI-4) and a criticality standard calculation route.The CRISTAL V2.0 package benefits from a broad validation database covering almost all areas of criticality-safety applications, from fuel fabrication to reprocessing, including transportation. 3,127 critical experiments, corresponding to 342 series, either issued from the OECD/ICSBEP Handbook or performed in French facilities (confidential data) were selected for the CRISTAL V2.0 validation database. Currently, more than 2,300 experiments are already part of the validation database.This validation work does not highlight significant (C - E) discrepancies and inter-comparisons between the different calculation routes mainly show good agreements on a large set of common experiments.
