In the framework of criticality safety, the validation of the APOLLO2-MORET 4 calculation route, performed by IRSN, is based on the calculation of more than 1800 integral experiments. Calculations were performed on this huge validation database using group-wise nuclear data libraries based on JEFF-3.1 evaluation files. Calculation-experiment discrepancies were analyzed regarding the neutron spectrum. This validation highlights that the JEFF-3.1 evaluation gives markedly better results than those obtained with the JEF-2.2 evaluated library for many of the criticality applications.
