Microstructural Characterization of Glass and Ceramic Simulated Waste Forms
Glass is currently the primary waste form candidate for immobilization of Hanford high level radioactive wastes from three generations of nuclear fuel reprocessing. Several chemically varied waste types must be immobilized, including sludges and highly concentrated liquids, and each may require a chemically different but optimum glass composition to fix the appropriate set of radionuclides. Efforts are also underway to evaluate the application of ceramic forms as an alternative to glass for the fixation of Hanford defense waste. Results of laboratory scale studies for fixation of these wastes into glass (1) and ceramic (2) forms have been reported and the studies are continuing.
