MCNP analyses of the JAEA/FNS iron experiment with the MCNP code for JENDL-5 showed that neutron fluxes above 10 MeV and below 10 keV were different at most by 10% between JENDL-4.0 and JENDL-5. Thus, we investigated the causes with the DORT code. Then it was found that the differences of the neutron fluxes above 10 MeV and below 10 keV were caused by those of the elastic scattering, (n,2n) and (n,np) reaction data in ⁵⁶Fe and those of the inelastic scattering data in ⁵⁶Fe and ⁵⁷Fe between JENDL-4.0 and JENDL-5, respectively.
