In fusion reactor structures, a serious damage mechanism has been gas production in the metallic resulting from diverse nuclear reactions, mainly through ( n , α ) and ( n , p ) reactions above a certain threshold energy. The neutron incident energy around 14–15 MeV is enough to excite the nucleus for the reactions such as ( n , p ), ( n , d ), ( n , 2 n ), ( n , t ), and ( n , α ). Design of the fusion reactor, about the 14–15 MeV neutron incident energy reaction cross sections is of great importance for various target nuclei. In this study, the experimental data have been taken only at 14–15 MeV energy regions from EXFOR database. The ( n , α ) reactions for some structural fusion materials such as 27 Al, 51 V, 52 Cr, 55 Mn, 56 Fe and 58 Ni have calculated by using evaluated empirical formulas developed by Tel et al. at 14–15 MeV and calculated with the pre-equilibrium models up to 20 MeV. The calculated results are discussed and compared with the experimental data taken from EXFOR database.
