TREATMENT ALTERNATIVES FOR GREATER-THAN-CLASS C LOW-LEVEL WASTE

Technically and economically viable treatment methods that are amenable to remote operation and that produce waste forms with acceptable properties are needed for treating Greater-Than-Class C lowlevel waste (GTCC LLW). Processes under consideration are size reduction, incineration, vitrification, cementation, decontamination, and plasma melting. Factors influencing the selection of these technologies, including waste characteristics and waste form disposal criteria, are discussed in this paper. The bulk of GTCC LLW is activated and contaminated metals, but other identified materials are combustible trash, cartridge filters, sludges, and ion exchange resins.
