Using optical model the developed of new cross section formula for tritium produced reactions 14-14 MeV induced neutron

Nuclear fusion can be one of the most attractive sources of energy in the future. Tritium self-sufficiency must be maintained for a commercial fusion power plant. For self-sustaining (D-T) fusion driver tritium breeding ratio should be greater than 1.05. So working out the systematics of (n,t) reaction cross sections are of great importance for the definition of the excitation function character for the given reaction taking place on various nuclei at energies up to 20 MeV. In this study, we have calculated non-elastic cross-sections by using optical model for (n,t) reactions at 14-15 MeV energy. We have obtained new coefficients for the (n,t) reaction cross-sections. We have suggested semi-empirical formulas including optical model nonelastic effects by fitting two parameters for the (n,t) reaction cross-sections at 14-15 MeV. The obtained cross-section formulas with new coefficients have been discussed and compared with the available experimental data.
