Radiation effects due to fission events were simulated in UO(2) and in simulated high burnup UO(2) so-called SIMFUEL, by irradiation with a typical fission product of fission energy, ie 72 MeV iodine ions obtained from the TASCC accelerator at Chalk River. Specimens pre-implanted with radioactive Kr(850 were used to measure fission enhanced gas release, formation of Kr-microbubbles in the fission spikes and indirectly, re-solution of gas from bubbles. These processes were known to exist but could now be quantified in out-of-pile experiments.
