Description

Iodine, rubidium, and krypton were ion-beam implanted into specimens of thoria, simulated high burnup thoria, and urania. Release of iodine from the thoria specimens was examined from 250 to 1700 degrees Celsius, and the results were compared with those from similar tests with xenon, reported previously. Differences between iodine and xenon behaviour in thoria are interpreted as evidence either for different intragranular mobilities or for surface influences on iodine. Release of iodine, rubidium, and krypton from simulated high burnup thoria fuel was not enhanced compared to release from fresh thoria. Transmission electron microscopy showed cube-shaped bubbles or bubble-like precipitates in urania implanted with iodine and heat treated at 900 degrees Celsius. Morphology changes in the bubbles at higher temperatures are described
