Abstract

This study evaluates the types of waste generated by tritium during nuclear fusion. Some methods of reprocessing and decontaminating solid waste using thermal processes are evaluated, and the advantages and disadvantages of different methods are compared. The high-temperature technology selected for this study is intended for use in the EU DEMO project in the area where waste from nuclear fusion reactions is processed. Safety and environmental concerns around the technology are evaluated. The potential for detritiation of solid wastes of various sizes are investigated. The study’s focus is on wastes comprising mostly tungsten dust grains of various sizes. The possibilities and rationale for the use of high-temperature technologies are investigated. Tests conducted focus primarily on tungsten waste in powder form in various atmospheres. Problems related to the induction heating and melting of metals and nonmetals are addressed.
