As part of its research and development program on waste conditioning, the CEA has developed a cold crucible induction melting technique suitable for a variety of materials: metals, molten salts or oxides including amorphous glass or vitrocrystalline. The technique can be used, for example, to produce containment glass at high temperatures without contamination of the feed material and without corrosion of the crucible itself. The material is heated to the core, but encased in a solidified shell of the same material that forms in contact with the water-cooled melter walls - a very warm {open_quotes}heart{close_quotes} in a cold {open_quotes}body{close_quotes}. This development opens the way to new and even more sophisticated containment matrices; new applications are already envisaged in the area of incineration: burning contaminated chlorinated plastic waste or even sulfonate ion exchange resins from thermal power stations is feasible without risk of corrosion by chlorine or sulfur. Waste incineration and containment of the residue may be performed simultaneously in a single reactor.
