METHOD OF RADIOACTIVE WASTE RESIDUES CONSERVATION IN STORAGE TANKS Russian patent published in 2017 - IPC G21F9/00 

FIELD: power industry.

SUBSTANCE: method for radioactive waste residues conservation in storage tanks involves filling the storage tank with concrete using standard production openings and drilled wells in which vertically movable concrete guides are installed through which the conserant concrete is laid in consecutive layers and liquid radioactive waste is pumped out. Wells are drilled at the periphery of the storage tank, where the preservative concrete is first laid, forming a depression around the suction branch pipe of the depression pump and displacing into it from the periphery of the liquid radioactive waste present in the storage tank, pumped out periodically as the area of the depression decreases and the level of liquid radioactive waste in it. After pumping into the cavity through a standard technological hole located above the cavity, a cement slurry is supplied.

EFFECT: invention makes it possible to reduce the volume of liquid radioactive waste cured in the tank.
