The solid-state diffusion of plutonium in uranium dioxide

Abstract Lattice and inter-diffusion coefficients of plutonium in uranium dioxide have been calculated from electron microprobe analysis of the interface of diffusion couples annealed at 2023, 2123 and 2223 K. The results show that grain-boundary diffusion predominates in the overall diffusion process. The inter-diffusion coefficient follows a trough-like function with stoichiometry, a minimum occurring at an oxygen-to-metal ratio around 1.97.
