Problems of DPA cross-sections above 20 MeV in FENDL-3.1d found in A-FNS neutronics analysis

Kwon, Saerom*; Konno, Chikara ; Ota, Masayuki*; Kasugai, Atsushi*

We found out that there was a questionable iron DPA value just above 20 MeV neutron energy in neutronics analyses of A-FNS using FENDL-3.1d. Our detailed investigation on the iron data in FENDL-3.1d figured out that residual nucleus production yield data of $$^{56}$$Fe just above 20 MeV had a problem, which caused a sharp spike just above 20 MeV in the DPA cross section of $$^{56}$$Fe. Thus we modified the yield data of $$^{56}$$Fe and verified that the questionable DPA value disappeared using the modified data. We also examined DPA cross sections of other nuclei in FENDL-3.1d. It was found out that DPA cross sections of more than 70% of nuclei in FENDL-3.1d have similar problems as that of $$^{56}$$Fe.
