ABSTRACT:
A process for the consolidation or stabilization of radioactive wastes in a glass matrix, wherein a glass smelt which has been enriched with the active material is solidified through cooling. The process is distinguished in that the maximally 1200.degree. C. hot gas smelt with the active waste within the final respository container is brought into contact prior to its cooling, at least along its surface, with a solid viscosity-increasing oxide up to at least a partial dissolution thereof. Among such oxides are aluminum oxide and zirconium oxide, wherein unsintered aluminum oxide is preferred.
