Title (EN) ALUMINO-BOROSILICATE GLASS FOR CONFINING RADIOACTIVE LIQUID EFFLUENTS, AND METHOD FOR PROCESSING RADIOACTIVE EFFLUENTS
(FR) VERRE ALUMINO-BOROSILICATÉ POUR LE CONFINEMENT D'EFFLUENTS LIQUIDES RADIOACTIFS, ET PROCÉDÉ DE TRAITEMENT D'EFFLUENTS LIQUIDES RADIOACTIFS
Abstract:
(EN) The invention relates to an alumino-borosilicate glass for confining a radioactive liquid effluent having medium activity. The invention also relates to a vitrification additive, and to a method for processing a radioactive liquid effluent having medium activity, comprising calcinating said effluent, adding the vitrification additive to said calcinate, melting the calcinate and the vitrification additive in a cold crucible in order to obtain a glass melt, and cooling the glass melt in order to obtain the alumino-borosilicate glass.
(FR) Adjuvant de vitrification. Procédé de traitement d'un effluent liquide radioactif de moyenne activité, dans lequel on réalise une calcination dudit effluent, pour obtenir un calcinât, puis on ajoute un adjuvant de vitrification audit calcinât, on procède à la fusion dudit calcinât et dudit adjuvant de vitrification dans un creuset froid pour obtenir une fonte verrière, puis l'on refroidit ladite fonte verrière pour obtenir le verre alumino-borosilicaté.
