METHOD FOR CONTAINER-FREE SUBSURFACE BURIAL OF SOLID RADIATION SOURCES IN ABANDONED DEEP WORKINGS OF CRYOLITE ZONE Russian patent published in 2005 - IPC

Abstract RU 2263985 C2

FIELD: evacuation of radioactive wastes.

SUBSTANCE: proposed method for container-free subsurface burial of solid radioactive wastes in abandoned deep workings of cryolite zone involves delivery of solid radiation sources pre-cooled in winter to abandoned mine workings. Radiation sources are placed in layer-by-layer manner on prepared falsework paled floor, leveled, compacted, flooded with water, and frozen by natural cold before piling radioactive wastes to full height of subsurface workings. In the process, burial ground is shaped in the form of pillar. Split ice is added in the course of placing layers of solid radioactive wastes including their forced cooling with cold atmospheric air.

EFFECT: enhanced reliability and safety.
