Abstract

Results are reported on several new glass and glass-ceramic wasteformulations for plutonium disposition. The approach proposed involvesemploying existing calcined high level waste (HLW) present at the IdahoChemical Processing Plant (ICPP) as an additive to: 1) aid in the formationof a durable waste form and 2) decrease the attractiveness level of theplutonium from a proliferation viewpoint. The plutonium, PuO2,loadings employed were 15 wt% (glass) and 17 wt% (glass-ceramic). Results inthe form of x-ray diffraction patterns, microstructure and durability testsare presented on cerium surrogate and plutonium loaded waste forms usingsimulated calcined HLW and demonstrate that durable phases, zirconia andzirconolite, contain essentially all the plutonium.
