Abstract

For simulating radiation damage of fusion reactors with high energetic neutrons the knowledge of neutron cross-sections has to be improved especially above 20 MeV. In this energy region the energy transfer is dominated by nuclear cascade reactions. For iron and the main additional elements of stainless steel like chromium and nickel the energy transfer has been determined for each type of cascade reaction separately. Using the evaporation model the energy spectra of the heavy recoil atoms as well as that of the smaller emitted particles were calculated with a Monte Carlo procedure. Applying the energy partition based on Lindhard theory we get the damage energy production cross-section and finally the dpa cross-section.
