Abstract
The ion microprobe mass analyzer was used to measure oxygen diffusivity in porous hyperstoichiometric uranium dioxide. The effect of porosity on diffusivity is discussed in terms of percolation theory. The limited data reported herein indicate a diffusivity threshold when the volume fraction of pores is 0̃.3. At this porosity, the oxygen diffusion changes from solid-like to gas-like behavior.
