A process for preparing a cartridge for disposal of a radioactive waste liquid, which comprises filling glass fibers in a mold, heat-treating the fibers for partial fusion and molding them into a molded product of a predetermined shape, wherein at least one member selected from the group consisting of boric acid, silicic acid, lithium borate, lithium silicate, zinc borate, zinc silicate, an organic silane, a silica sol, an oil emulsion, and an alumina sol, is applied to the glass fibers or to the molded product.

Process for preparing a cartridge for disposal of a radioactive waste

An electric melting furnace for glassifying high-radioactive waste characterized in that, in a furnace for melting glass containing platinum-group elements which has an outlet of glass at the bottom part of a melting tank, the bottom of the furnace surrounding the outlet has an inclination of more than 30.degree. and not more than 70.degree. with respect to the horizontal plane toward the cullet, and the distance l.sub.1 between a surface-inside opening part of the outlet and bottom ends of at least a pair of electrodes (3a, 3b) for supplying most of power required for glass melting is a half or more, but not exceeding, of the distance (l.sub.2) between the electrodes (3a, 3b).
