Volatile Impurities in the Plutonium Immobilization Ceramic Wasteform

PDF Version Also Available for Download.

Description

Approximately 18 of the 50 metric tons of plutonium identified for disposition contain significant quantities of impurities. A ceramic waste form is the chosen option for immobilization of the excess plutonium. The impurities associated with the stored plutonium have been identified (CaCl2, MgF2, Pb, etc.). For this study, only volatile species are investigated. The impurities are added individually. Cerium is used as the surrogate for plutonium. Three compositions, including the baseline composition, were used to verify the ability of the ceramic wasteform to accommodate impurities. The criteria for evaluation of the effect of the impurities were the apparent porosity and ... continued below

The criteria for evaluation of the effect of the impurities were the apparent porosity and phase assemblage of sintered pellets.
