METHOD FOR VITRIFYING SULPHUR-CONTAINING RADIOWASTES Russian patent published in 1996 - IPC

Abstract RU 2065215 C1

FIELD: liquid radiowastes immobilization in solid stable medium. SUBSTANCE: dry residue of sulphur-containing radiowastes is mixed up with vitrifying dopes; calcium fluoride in amount of 6-10 mass percent 3-10 mass percent of residue sulfate ions is introduced in mixture. Charge obtained is heated up to formation of glass melt whereupon the latter is cooled down in solid state. EFFECT: simplified procedure, improved water resistance of end product.
