Abstract

A quantitative X-ray powder diffraction study was made of actinide-doped perovskite of bulk composition Ca_0.98919An_0.01081Ti_0.98919Al_0.01081O₃ where An corresponded to approximately equimolar proportions of Cm-244 and Pu-240. Isochronal annealing was carried out at high temperatures for 12 hours to establish the critical temperature under the reducing conditions of geological repositories. Materials which have sustained doses of 1.6-4.0×10¹⁷ alpha decays per gram were subjected to MCC-1 leach tests for two months. Perovskite dissolution and titanium precipitation were studied under these conditions.
