Beschreibung
Zusammenfassung:	A method for concentrating and/or entrapping radioisotopes from an aqueous solution, said method comprises mixing the aqueous solutions with at least one inorganic salt under conditions in which said salt forms at least one stable hydrate, incorporating the tritium as water of crystallisation. Said hydrate will neither react nor degrade for extended periods of time, and accordingly a method of stabilising large amount of radioactive waste is provided. L'invention concerne un procédé permettant de concentrer et/ou piéger des radio-isotopes à partir d'une solution aqueuse, ledit procédé consistant à mélanger les solutions aqueuses avec au moins un sel inorganique dans des conditions dans lesquelles ledit sel forme au moins un hydrate stable, en incorporant le tritium comme eau de cristallisation. Ledit hydrate ne réagira ni ne se dégradera pendant de longues périodes de temps ; par conséquent, l'invention concerne un procédé de stabilisation d'une grande quantité de déchets radioactifs.
