Estimation of radiation damage of iron by a reactor gamma spectrum

Abstract

AbstractRadiation damage of Iron by a gamma spectrum of a high flux isotope reactor is estimated using our JAIPU Monte Carlo code developed for the estimation of radiation damage by neutron and gamma radiation up to 10 MeV energy. The rate of displacement per atom is estimated to be ∼1.389E-10/sec at 30 cm radial distance in the HB-2 tube of the reactor. Production of displaced atoms is found to be an order of magnitude higher than the number of defects. Ratio of the rates of displacement per atoms by gammas to neutrons of the reactor deduced from calculations is found to be consistent with the earlier reported result.
