Abstract: We show that competition between nucleation of voids and diffusion of mobile defects in the presence of heterogeneously distributed dislocations in the vicinity of a grain boundary in an irradiated material gives rise to the formation of a spatially inhomogeneous profile of void swelling. The proposed model is able to explain a number of experimentally observed features characterising the efiect, including the formation of void denuded zones and the occurence of iarge voids in the vicinity of grain boundaries.
