After a few mistaken ideas about the management of tritiated wastes, towards 1980, a global strategy was established for reprocessing all tritiated gaseous, liquid and solid wastes so that eventually, there will be no tritiated wastes. Meantime, safe interim storage of wastes is ensured at VALDUC Centre, after reprocessing. Solid wastes are classified in terms of degassing rate and storage buildings constructed taking due account of the various contamination levels. New reprocessing methods should solve the problem in the future by elimination, de-commissioning or disposal. Solid waste originating in controlled-fusion reactors will prove a critical problem in the future because of the nature of the materials and the presence of highly-gamma-irradiating activation products. Therefore, high-standard methods are required for reprocessing tritiated products to be placed in final sub-soil disposal sites.
