FIELD: immobilizing radioactive wastes.
SUBSTANCE: proposed method includes filling melting crucible with charge and melting the latter. Molten charge is drained through melting crucible die hole to container wherein glass is additionally melted. Charge is melted, charge melt is poured into container, and glass is additionally melted in common heating zone. Device for manufacturing high-level glass filled container has melting crucible incorporating die hole and bottom part, and container. Melting crucible is disposed above container on spacer ring in common heating zone. Spacer ring height is greater than total height of container and die hole. Ratio of die hole diameter to its height is chosen to ensure formation of thermal plug therein from solidified glass produced in previous melting process.
EFFECT: enhanced reliability of immobilizing radioactive wastes.
