Differential thermal analysis has been successfully applied to highly radioactive irradiated materials through use of a disposable sample holder and appropriate remotely-operated equipment; measurement of the temperature at which radiation damage is annealed, as well as the quantity of energy released, has been obtained. In the cases of irradiated, amorphous U3O8 and A12O3, the energy release associated with the return of crystallinity was measured; results of the measurements indicate that these amorphous materials are supercooled liquids, that is, true glasses. Negative runs were obtained on differential thermal analysis runs on UO2 and ZrO2–UO2.
