Study of Some Structural Fusion Materials for (n,2n) Reactions

Studies of (n,2n) reaction are especially important for neutron multiplication. The (n,2n) cross section is neutron multiplier reaction in fusion reactor design. Al-27, V-51, Cr-52, Mn-55, Fe-56 and Ni-58 nuclei are the some structural fusion materials. Therefore, (n,2n) reactions of the selected blanket materials can play a key role for multiplying neutrons in reactor environment. In this study, for some structural fusion materials (n,2n) reactions such as Al-27(n,2n)Al-26, V-51(n,2n)V-50, Cr-52(n,2n)Cr-51, Mn-55(n,2n)Mn-54, Fe-56(n,2n)Fe-55 and Ni-58(n,2n)Ni-57 have been carried out up to 30 MeV incident neutron energy. In the calculations, the pre-equilibrium and equilibrium effects have been used. The calculated results have been compared with the experimental data as well as with evaluated data files.
