Abstract Consideration is given to the kinetics of development of an ensemble of dislocation loops of the interstitial type and of line edge dislocations in a material which is subjected to uniaxial stress under irradiation. It is shown that at sufficiently high tensile stresses in this system an increased growth of the dislocation loops with Burger's vectors along the load axis leads to evaporation of dislocation loops of other orientations at later stages of irradiation. Estimates are given of characteristic times of this process as functions of the material parameters and irradiation conditions. The rate of radiation creep of the stressed material has been determined, bias factors of the line dislocations obtained with allowance for microscopic processes in the dislocation core being used in its calculation. This gives rise to a temperature dependence of the material creep rate at the initial stages of irradiation, in which case the creep rate increases with decreasing irradiation temperature. It is al...
