/sup 238/Pu-substituted cubic zirconolite (CaPuTi/sub 2/O/sub 7/) was stored at ambient temperature, 575 K and 875 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 K lesser amounts of swelling (4.1 vol%) and transformation were observed, reflecting concurrent partial recovery. The material held at 875 K remained crystalline, swelled only 0.4 vol%, and exhibited formation of isolated defect clusters.
