Abstract

Abstract

CENDL-3.2 Library updated the ⁵⁶Fe inelastic scattering cross section. In order to verify the difference of cross-section and the shielding computing ability between the CENDL-3.2 Library and ENDF/B-Ⅷ.0 Library, NJOY2016 program was used to compare the microscopic cross section of ⁵⁶Fe after resonance reconstruction, such as inelastic scattering, total cross section, and the multi-group cross section library was also made. Three series of shielding benchmarks, ILL-Fe, OKTAVIAN-Fe and IPPE-Fe, are selected in the range of ⁵⁶Fe inelastic scattering energy, and ⁵⁶Fe is used as the main nuclide. The results show that the inelastic cross section of CENDL-3.2 Library is lower than that of ENDF/B-Ⅷ.0 Library in the range of 4MeV~12MeV. The multi-group cross-section benchmark verification showed that the calculated results of CENDL-3.2 Library are in good agreement with the experimental values. For OKTAVIAN-Fe benchmark, the results of the two Libraries agree well in the range of 0.1MeV~1MeV. In addition, the same phenomenon is found in all the benchmark tests, that is, in the energy range of 1MeV~10MeV, where the ⁵⁶Fe inelastic cross section is the main contribution, the results of CENDL-3.2 Library are higher than those of ENDF/B-Ⅷ.0 Library.
