METHOD FOR PROCESSING LIQUID RADIOACTIVE WASTE Russian patent published in 2023 - IPC G21F9/06 

Abstract RU 2809345 C1

FIELD: nuclear energy.

SUBSTANCE: invention can be used in processing of liquid radioactive waste. The method for processing liquid radioactive waste includes preliminary treatment of the initial radioactive solution to obtain a filtrate and remove impurities. Subsequent treatment of the filtrate is carried out using a membrane apparatus. To treat radioactive filtrate, direct osmosis technology is used, in which radioactive solutions with pH value of no higher than 6 and with an initial salt content of no more than 16 g/L are sent for treatment, while ensuring membrane permeability in the range from 0.2 to 0.5 m3/m2*h.

EFFECT: improved efficiency of waste treatment.
