For many years now, IRSN has developed its own Monte Carlo continuous energy capability, which bottle cage allows testing various nuclear data libraries.In that prospect, a validation database of 1136 experiments was built from cases used for the validation of the APOLLO2-MORET 5 multigroup route of the CRISTAL V2.0 package.In this paper, the keff Chafers obtained for more than 200 benchmarks using the JEFF-3.1.

1 and JEFF-3.2 libraries are compared to benchmark keff values and main discrepancies are analyzed regarding the neutron spectrum.Special attention is paid on benchmarks for which the results have been highly modified between both JEFF-3 versions.
