Performance of CENDL-3.2 evaluated nuclear data library for the shielding benchmarks

Highlights: • CENDL-3.2 is processed into shielding libraries with NECP-Atlas and NECP-Hydra. • The performance of CENDL-3.2 are acceptable in shielding benchmarks. • The cross section of ⁵⁶Fe in CENDL-3.2 make the results better than other libraries. The latest CENDL-3.2 evaluated nuclear data library was released in June 2020. To verify the capability of CENDL-3.2 in shielding benchmarks, a broad-group shielding library is produced using NECP-Atlas based on CENDL-3.2, following the generation method of BUGLE library. Other broad-group shielding libraries based on evaluated nuclear data libraries including ENDF/B-VII.0, ENDF/B-VII.1 and ENDF/B-VIII.0 are also generated for comparison. The broad-group libraries are firstly validated against several benchmarks, and then used for the calculation of shielding benchmarks including Iron-88, PCA-Replica and HBR-2. The numerical results indicate that the accuracy of the results obtained with CENDL-3.2 in these shielding benchmarks is acceptable. For the Sulphur dosimeter in Iron-88, CENDL-3.2 gives better performance, and through detailed analysis, it is found that the difference is mainly caused by the reevaluation of the inelastic and elastic scattering cross sections of ⁵⁶Fe.
