METHOD OF PROCESSING LIQUID RADIOACTIVE WASTES Russian patent published in 2017 - IPC G21F9/16 

FIELD: chemistry.

SUBSTANCE: method of purifying liquid radioactive wastes (LRW) includes the steps of heat treatment, LRW purification is carried out in two stages. LRW is placed in the treatment tank by the pump from the first vessel and a strain of fungus of the second container. LRW ratio and fungal strains are selected in a proportion of 1 to 15 by a motor-reducer in the treatment tank produce mixing LRW and fungi strains at a speed of 5 rev/min, followed by a gas burner, located under the bottom of the working tank produce its gradual heating of the first 30°C, maintaining the temperature for 12 hours. Evaporation of the resulting mixture is produced by further warming the working tank to a temperature of 538°C. Evaporation is carried out until the moment when the treatment tank via the level sensor is fixed to 2/3 of the initial solution level.

EFFECT: invention reduces the amount of liquid radioactive waste, and to reduce their level of radioactivity.
