“…The k eff calculations were performed, for the selected benchmarks, with the 5.D.1 beta version of the MORET 5 [11] code, using JEFF-3.2. In addition, k eff calculations were performed using JEFF3.2, together with the new 235 U evaluation.…”

Abstract. The Working Party on International Nuclear Data Evaluation Co-operation (WPEC) subgroup 29 (SG 29) was established to investigate an issue with the 235 U capture cross-section in the energy range from 0.1 to 2.25 keV, due to a possible overestimation of 10% or more. To improve the 235 U capture crosssection, a new 235 U evaluation has been proposed by the Institut de Radioprotection et de Sûreté Nucléaire (IRSN) and the CEA, mainly based on new time-of-flight 235 U capture cross-section measurements and recent fission cross-section measurements performed at the n TOF facility from CERN. IRSN and CEA Cadarache were in charge of the thermal to 2.25 keV energy range, whereas the CEA DIF was responsible of the high energy region. Integral experiments showing a strong 235 U sensitivity are used to assess the new evaluation, using Monte-Carlo methods. The k ef f calculations were performed with the 5.D.1 beta version of the MORET 5 code, using the JEFF-3.2 library and the new 235 U evaluation, as well as the JEFF-3.3T1 library in which the new 235 U has been included. The benchmark selection allowed highlighting a significant improvement on k ef f due to the new 235 U evaluation. The results of this data testing are presented here.

“…The full JEFF-3.3T1 library was processed with GAIA 1.1 and the k eff calculations were performed for the same benchmark selection with the 5.D.1 beta version of the MORET 5 [11] code. The C/E results obtained using full JEFF-3.3T1 library are shown in Fig.…”

Abstract. For many years now, IRSN has developed its own Monte Carlo continuous energy capability, which 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 k eff obtained for more than 200 benchmarks using the JEFF-3.1.1 and JEFF-3.2 libraries are compared to benchmark k eff 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.

“…Over the last two decades, the need of Monte Carlo (MC) methods and its techniques for modeling complex systems are growing Vaz, 2010;Cochet et al, 2014). Analytical modeling of complex system is tedious and error-prone (Wu and FDS Team, 2009a;Song et al, 2014).…”
