Abstract: This work is aimed for justification of quantitative effect of radiation defect concentration decreasing in materials depending on density of edge dislocation which are their outlet. The results of defect kinetics modeling with taking into account their recombination on dislocation loops, edge dislocations and pores are given. The summery of this work is useful in the frame of solving problem of decreasing radiation swelling and material properties degradation during neutron irradiation.
