Low-Level Radioactive Waste Vitrification LLWV is a technically feasible and cost competitive alternative to the traditional immobilization options, i.e., cementation or bituminization. This thesis analyzes cementation, bituminization and vitrification, reviews the impact of the Low-Level Waste stream composition on the vitrification process, then proposes and discusses several techniques to control the votile radionuclides in a Process Improved LLWV system PILLWV. The techniques that control the volatile radionuclides include chemical precipitation, electrodialysis, and iuon exchange. Ion exchange is preferred. A comparison of the technical specifications, of the regulatory compliance, and of the cost considerations shows the PILLWV to be the superior LLW immobilization option. Author
