Effect of neutron irradiation on low-cycle fatigue of structural materials (Review)

Abstract

One of the main problems in modern reactor construction is ensuring the reliability of fuel elements and other design elements of the reactor cores working under the conditions of the effect of elevated temperatures, mechanical stresses and high-intensity neutron irradiation. The goal of this work was to generalize the existing experimental results on the effect of radiation on fatigue life. The review is based mainly on the experimental data for austenitic corrosion-resistant and some other steels, which are the most promising structural materials both for nuclear reactor cores and for the first wall of the TNR.
