1. A method of inclusion melting of glass with radioactive components, particularly from the reprocessing of nuclear fuel elements, comprising:
- feeding radioactive components in the form of one of an aqueous solution or of a slurry into a furnace from above in combination with a mixture suitable for the melt-forming of glass; and
heating the molten mass of glass and radioactive components by passing electrical current directly therethrough, wherein the mass flow takes place solely vertically from top to bottom.

Abstract
A method of inclusion melting of glass with radioactive components and a furnace for carrying out the method. Radioactive components are fed in the form of an aqueous suspension or of a slurry into a furnace from above in combination with a mixture for the melt forming of glass, or the mixture for the melt forming being formed from the radioactive components. The molten mass of glass and radioactive components is heated by passing electrical current directly therethrough, wherein the mass flow takes place solely vertically from top to bottom.
