| 内容記述 | Previously we benchmarked the iron and concrete shielding experiments with 40 and 65 MeV neutron sources at QST/TIARA by using ENDF/B-VII.1, FENDL-3.0 and JENDL-4.0/HE. We pointed out that the calculated results with ENDF/B-VII.1 excessively overestimated the measured neutron fluxes more in the thicker test shields in both of the experiments. It was confirmed that the overestimations were due to elastic and non-elastic scattering data of 56Fe and 16O in ENDF/B-VII.1. Several beta versions of ENDF/B-VIII were released in 2016. We analyze the same experiments with ENDF/B-VIIIb2 (2nd beta version which was released in August, 2016) to investigate whether the 56Fe and 16O data in ENDF/B-VIIIb2 are improved. In the iron experiment, the excessive overestimation in the calculated result with ENDF/B-VII.1 decreases in that with ENDF/B-VIIIb2, due to the revision of the elastic and non-elastic scattering cross section data of 56Fe in ENDF/B-VIIIb2. However, the excessive overestimation in the calculated results with ENDF/B-VII.1 does not change in that with ENDF/B-VIIIb2 in the concrete experiment because the 16O data above 20 MeV are not revised in ENDF/B-VIIIb2. The final version of ENDF/B-VIII should be modified based on these results. | |||||
