A combination of 300 keV Kr-84 ion implantation and Time-of-Flight Elastic Recoil Detection Analysis is utilised to investigate the diffusion of Kr in UO2 and ADOPT (TM) fuels. Composition depth-profiles on the nanometer scale were obtained, both for as-implanted samples and after annealing at 800 degrees C for 1 h. Observed drifts in the 84Kr profiles could be associated with short-range diffusion mechanisms. The approach employed here provides the possibility to make direct comparisons with atomistic scale modelling data, and can be of service as a separate effect test in line with the Accelerated Fuel Qualification initiative.
