16 49,146 ABSTRACT OF THE DISCLOSURE Disclosed is a method of immobilizing nuclear waste in glass. A composition is prepared of about 30 to about 85% of a hydrolyzed glass-forming silicon compound, about 5 to about 30% of a glass-forming sodium compound, up to about 30% of a glass-forming aluminum compound, and about 5 to about 30% of a glass-forming boron, calcium, or magnesium compound. Up to an equal amount of nuclear waste is mixed into the composition and the mixture is heated at up to 500°C until dry. The mixture is then melted at 800 to 1300°c, and can be poured into ingots and cooled. The mixture can also be melted in situ with a laser.
