Innovative plasma routes for liquid radwaste processing


Nuclear fuel cycle operation, production and application of radioisotope in biological investigation, industry,research.are as much sources of liquid radioactive waste. Some of them are currently treated to immobilize theirradionuclides before final repository when others are waiting for suitable processes.For several years, the CEA has worked to adapt plasma technology to liquid treatment. Among the followed technologicaltracks, two have been considered as promising because rapid and very effective. The first, involving aerial inducted plasmatorch, ensures the treatment by feeding the liquid in the hearth of the inductive coil, directly into the plasma plume. Thesecond, involving submerged non transferred plasma torch into which the liquid is also fed, has the particularity to useunderwater plasma in order to avoid corrosion and to extend the range of waste that can be treated.The aim of this paper is to provide a description and the performances of these two processes displaying large potentialitiesthrough their originality. Several radwastes could find their outlet thanks to these two new routes.
