[en] A study was performed to determine the technical and economic viability of applying vitrification to volume reduction and immobilization of nuclear power plant radioactive waste (radwaste). Vitrification technology has been extensively developed in the United States and abroad for immobilization of high-level radioactive waste. A conceptual design of a facility to vitrify light-water reactor radwaste (except noncompactible/noncombustible wastes) was developed. Technical, economic, and safety evaluations were performed for waste vitrification. Technical and economic comparisons were made with available technologies for radwaste volume reduction and immobilization. It was concluded that vitrification is a viable and competitively attractive approach; however, some additional process verification should be conducted prior to plant application
