Nuclear model calculations of cross sections of alphas-induced reactions

Cross section calculations for alpha-induced reactions on fusion reactor materials are very important for the development of reactor technology. In particular, the calculation and measurements of the data in the energy regions with the maximum cross sections are important to define the characteristic of the excitation function. In this thesis, nuclear model calculations were made to obtain cross sections of reactions induced by alphas on some reactor materials. ALICE/ASH and TALYS 1.9 nuclear reaction codes were used in these calculations. The geometry dependent hybrid model and the two component exciton model were used at pre-equilibrium calculations. The equilibrium calculations for obtaining cross sections were made using Weisskopf-Ewing and Hauser-Feshbach models. The cross sections obtained from all these calculations were compared with the available experimental data and the results were discussed.
