Recent developments concerning the mechanism for volume diffusion of xenon in UO2 and the defects observed in irradiated UO2 by electron microscopy are reviewed with detailed reference to recent results obtained at Chalk River Nuclear Laboratory (CRNL). An earlier interpretation for xenon diffusion in a matrix containing pre-existing and irradiation induced trapping sites is extended.
