/sup 238/Pu-substituted cubic zirconolite (CaPuTi/sub 2/O/sub 7/) was stored at ambient temperature, 575/sup 0/ K, and 875/sup 0/ K until alpha decay doses of 2.4 to 3.6 x 10/sup 25//m/sup 3/ had been accumulated. The ambient temperature material swelled to a saturation value of 5.5 vol %, and the originally crystalline structure was transformed to one with an amorphous matrix and small domains that had retained their crystallinity. At 575/sup 0/ K, lesser amounts of swelling (4.1 vol %) and transformation were observed, reflecting concurrent partial recovery. The material held at 875/sup 0/ K remained crystalline, swelled only 0.4 vol %, and exhibited formation of isolated defect clusters. 5 figures.
