<sup>59</sup>Ni accumulation in corrosion-resistant steel under the action of neutron flux

Abstract

A γ-ray line with energy E _γ = 11.3 MeV was detected during an experiment, performed on a nuclear reactor, investigating the characteristics of the energy spectrum of γ-rays. The most likely source of this line is radiative capture of thermal neutrons by ⁵⁹Ni nuclei, which accumulated in the corrosion-resistance steel as a result of the more than 20 years of irradiation in the reactor, via the reaction ⁵⁸Ni(n, γ) ⁵⁹Ni. It was found that for thermal-neutron fluence 10 ²¹ cm ^-2 the ⁵⁹Ni concentration is 0.47% of the ⁵⁸Ni concentration.
