Abstract

L'invention concerne un procédé pour traiter de l'eau radioactive qui comprend une étape de concentration par congélation qui consiste à produire de la glace de plus faible concentration en substances radioactives, en congelant l'eau contaminée qui contient lesdites substances et en concentrant celles-ci dans l'eau contaminée résiduelle par concentration par congélation progressive d'interface.
