ALUMINO-BOROSILICATE GLASS FOR CONFINING RADIOACTIVE LIQUID EFFLUENTS, AND METHOD FOR PROCESSING RADIOACTIVE EFFLUENTS

摘要

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.
