Characterization of a Plutonium-Bearing Zirconolite-Rich Synroc
TL;DR: A titanate-based ceramic waste form, rich in phases structurally related to zirconolite (CaZrTi2O7), is being developed as a possible method for immobilizing excess plutonium from dismantled nuclear weapons.

Corrosion behavior of pyrochlore-rich titanate ceramics for plutonium disposition: Impurity effects
TL;DR: The results from 3 day, 90 C MCC-1 tests with impurity ceramics were significantly different than the results from tests with the baseline ceramic as mentioned in this paper, which is made up of only four phases, pyrochlore, zirconolite, rutile, and brannerite.

TL;DR: In this article, the authors reported x-ray absorption near edge structure (XANES) and extended xray absorption fine structure (EXAFS) spectra from the plutonium L{sub III} edge and XANES from the cerium L{ sub II} edge in prototype titanate ceramic hosts.
The Long-Term Corrosion Behavior of Titanate Ceramics for Pu Disposition: Rate-Controlling Processes
TL;DR: In this paper, the corrosion behavior of a titanate ceramic was investigated with the aim of describing the rate-controlling process or processes, and three important observations were made: (a) Ca is released at a constant rate [6x10{sup -5}g/(m{sup 2} day)] in PCT-B tests for up to two years, (b) all of the test leachates are oversaturated with respect to rutile and anatase, and (c) the release rates for Pu and Gd increase with time (up to two

TL;DR: In this paper, a full suite of microscopic techniques is used to characterize altered and unaltered samples, including optical, scanning electron, and transmission electron microscopies, for the presence of crystalline phases and amorphous material.
