Abstract

A new ²³⁵U capture cross-section evaluation, evaluated by ORNL and the CEA Bruyères-le-Châtel (BRC) has been proposed within the CIELO project. IRSN, who participates in the CIELO project, contributes with data testing and has carried out benchmark calculations using few benchmarks, extracted from the ICSBEP database, for testing the new ²³⁵U evaluation. The benchmarks have been selected by privileging the experiments showing small experimental uncertainties and a significant sensitivity to ²³⁵U capture cross-section. The k_eff calculations were performed with both the MCNP 6 code and the 5.C.1 release of the MORET 5 code, using the ENDF/B-VII.1 library for all isotopes except ²³⁵U, for which both the ENDF/B-VII.1 and the new ²³⁵U evaluation was used. The benchmark selection allowed highlighting a significant effect on k_eff of the new ²³⁵U capture cross-section. The results of this data testing, provided as input for the evaluators, are presented here.
