N2 - Quantitative powder X-ray diffraction was used to analyze the phase assemblages of titanate nuclear waste ceramics doped with 244Cm and accumulating α-decay doses up to 1.24 x 1018 alpha-decay-events g-1. Among the Cm-bearing phases, perovskite is more susceptible to damage than zirconolite. Phases devoid of curium (hollandite and freudenbergite) experience a flux of ionizing radiation, and may also undergo radiation-induced structural degradation. The analysis demonstrated that at a dose of 1.24 x 1018 alpha-decay-events g-1 approximately 20 wt% of the waste phases remain aperiodic after annealing for 2 hours at 800°C.
