Quantitative X-ray diffraction analysis of titanate waste forms and its application to damage ingrowth
Abstract
Quantitative powder X-ray diffraction was used to analyze the phase assemblages of titanate nuclear waste ceramics doped with {sup 224}Cm and accumulating {alpha}-decay doses up to 1.24 {times} 10{sup 18} alpha-decay-events g{sup -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 a dose of 1.24 {times} 10{sup 18} alpha-decay-events g{sup -1} approximately 20 wt% of the waste phases remain aperiodic after annealing for 2 hours at 800{degrees}C.
