Cross section calculations of neutron poison isotopes in fission reactors

In this thesis, the theoretical calculations of and (n,p) reaction cross sections between 2 - 20 MeV for 95Mo, 99Tc, 101Ru, 103Rh, 105Pd, 133Cs, 143Nd, 147Sm, 149Sm isotopes known as neutron poison in the reactors were performed. Equilibrium and equilibrium models were used in the calculations. In the calculations of and (n,p) reaction cross sections, PCROSS program was utilized for Weisskopf-Ewing and Full Exciton Model, while the program ALICE/ASH was used for Equilibrium, Hibrid and Geometry Dependant Hyrid Model. Results of performed cross-section calculations were compared within each model, with experimental data gathered from EXFOR (Experimental Nuclear Reaction Data) Database and with evaluated data taken from JANIS (Java-based Nuclear Information Software).
