【 摘 要 】

A Monte Carlo simulation code is developed for the study of neutron induced radiation damage in the materials which results from nuclear collision as well as reactions that create energetic recoil atoms of the host material or reaction creates. The aim of this work is to investigate the impact of the radiation damage in the iron by the neutron energy irradiation. The damage parameter used in the evaluation is displacement per atom DPA in material as a function of neutron energy. For this purpose, the simulations were carried out using the Monte Carlo transport code MCNP to calculate the DPA cross section for iron. It was determined that the maximum number of displaced atoms was approximately 1.73E-03 DPA.
