Vitrification of radioactive waste has been developed in Russia since 1960, and has been applied on an industrial scale to vitrify liquid high-level waste from reprocessing of spent fuel. In this report the state of vitrification practice has been analysed starting with a description of the reprocessing plants and their products. The research and development activities were focused on investigations of silicate and phosphate glasses. After operating some experimental melters, the first industrial-scale melter EP-500 was built at the Mayak reprocessing plant. This plant was decommissioned after 13 months of operation, and a new melter was built in 1990, which has been in active operation since 1991. Flowsheets, feed compositions and sketches of installations are included in the report, which also briefly addresses vitrification processes under development for solidifying low-level waste.
