Ongoing research investigations are on the way that will lead to a commercial fusion reactor. The study of radionuclides generated in the fusion reactor is of great importance. A lot of essential nuclear data can be extracted from the produced radionuclides in the reactor. Present research work is associated with the production pathways (inventories) and amount or activity of radionuclides of iron(55Fe, 59Fe, 60Fe) produced in the fusion reactor during its operation. The study is concentrated on production pathways and the cross section for the formation of radioisotopes 55Fe, 59Fe & 60Fe. These radionuclides are produced when a 14.1MeV neutron from the D-T plasma interacts with the wall material of fusion reactor. The Amount of these radionuclides produced through major pathways is calculated. The production cross sections via each pathway are calculated using the latest version of nuclear modular code TALYS-1.9. These cross sections are also compared with the experimental data available from EXFOR and evaluated nuclear data libraries. The pathway of maximum yield for the production of these radionuclides is identified. Some of the 14.1MeV neutrons interact with the reactor wall material and displace the atoms from their positions in crystal lattice, recoil spectra of daughter nuclei are crucial. Present investigation reveals that the radionuclides 55,59,60Fe are produced in the fusion reactor in sufficient amount that is harmful for the reactor health. The amount(activity) of radionuclides, major pathways, production cross section study is also included in details.ennullThesis
