Cyclic Reverse Osmosis Purification of Liquid Radioactive Waste

The results of experimental research of technology of reverse osmosis treatment of liquid radioactive waste (LRW) in successive cycles with return of permeate of the previous cycle to the consumer and separation of radioactive concentrate, directed to the subsequent cycle, are presented. The positive result obtained for the isotope 90Sr is noted. It is concluded that reduction of the volume of radioactive residue to be utilized allows increasing the ecological and economic efficiency of LRW processing and disposal while reducing the ecological load on the environment.
