JENDL-5 benchmark test for shielding applications

説明

JENDL-5 was validated from a viewpoint of shielding applications under the Shielding Integral Test Working Group of the JENDL Committee. The following benchmark experiments were selected: JAEA/FNS in-situ experiments, Osaka Univ./OKTAVIAN TOF experiments, ORNL/ JASPER sodium experiments, NIST iron experiment and QST/TIARA experiments. These experiments were analyzed with MCNP and nuclear data libraries (JENDL-5, JENDL-4.0 or JENDL-4.0/ HE, ENDF/B-VIII.0 and JEFF-3.3). The analysis results demonstrate that JENDL-5 is comparable to or better than JENDL-4.0 or JENDL-4.0/HE, ENDF/B-VIII.0 and JEFF-3.3 for neutron fluxes above 10 MeV in FNS in-situ iron experiment, neutron fluxes below 1 keV in FNS in-situ iron experi-ment, reaction rates of the 197Au(n,γ)198Au and 186W(n,γ)187W reactions in FNS in-situ copper experiment, neutron fluxes below 1 MeV in OKTAVIAN titanium experiment, neutron fluxes in OKTAVIAN manganese experiment, and neutron fluxes above 10 MeV in TIARA iron experiment.
