High-level radioactive liquid wastes are currently stored in underground tanks at several Department of Energy facilities. The current plan for management of these wastes is to convert them to a durable borosilicate glass, then isolate the glass in a deep geologic repository. The process for converting the wastes to glass involves mixing the high-level wastes with glass-forming chemicals, then transforming the resulting slurry into glass using a high-temperature furnace known as a slurry-fed ceramic melter. Maintaining the quality of the glass product and proficient melter operation depends on the ability of the waste slurry preparation and feed systems to produce and maintain a homogeneous mixture of waste and glass-former materials. This document reviews current technology. 11 refs., 18 figs., 15 tabs.
