METHOD FOR THERMAL RECOVERY OF SOLID ASH- CONTAINING RADIOACTIVE WASTES Russian patent published in 2001 - IPC

Abstract RU 2170965 C1

FIELD: environment protection; wastes recovery by immobilizing them in stable solid medium. SUBSTANCE: wastes are mixed up with powdered potassium permanganate, aluminum, calcium-silicon alloy, and boron. Mixture obtained is placed in container and ignited to initiate exothermic reaction between mixture components; in the process temperature rises to such extent that mixture transfer to glass-like melt is ensured. Then melt is cooled down due to natural temperature drop until solid end product is obtained. EFFECT: enlarged functional capabilities; increased mass content of solid ash-containing radioactive wastes in end product.
