    Abstract

    The existing analytical model that describes metal swelling under fast neutron irradiation is reviewed. The assumption of quasi-steady state and uniform point defect generation used in the present model is partially justified. Possible effects, due to microstructural defect interactions, that may occur at high fluences are discussed. The effect of stress field on point defect migration and its consequences on metal swelling and creep are considered.
