Creators

Description

Description is given of a method for improving the manufacture of molten glass containing radioactives substances to be eliminated. The liquid radioactive waste and pieces of glass are introduced into a moving bed calcinator, the inlet and outlet of which are heated to about 120 deg C and 400 deg C, respectively. The thus obtained calcined product is driven towards a furnace for being melted. That method can be used for processing radioactive wastes

Abstract (French)

On decrit un procede permettant d'ameliorer la technique de fabrication du verre fondu contenant des produits radioactifs a eliminer. On introduit les residus radioactifs liquides et des elements de verre dans un calcinateur a lit mobile dont l'entree et la sortie sont chauffees respectivement a environ 120 deg C et 400 deg C avant de diriger le calcinat ainsi obtenu vers un four de fusion. Ce procede est applicable au traitement des residus radioactifs
