METHOD OF CREATING BARRIER in situ FOR PREVENTING MIGRATION OF COMPONENTS OF RADIOACTIVE WASTES FROM BURIAL AREAS AND RADIOACTIVE CONTAMINATION REGIONS Russian patent published in 2015 - IPC G21F9/00 

FIELD: physics, atomic power.

SUBSTANCE: invention relates to means of burying and recycling liquid radioactive wastes and can be used at facilities storing radioactive wastes of low and medium activity in storages of different types, as well as in radioactive contamination areas with potential escape of components of radioactive wastes into the environment. The disclosed method includes selecting effectively high radio-resistant strains of microorganisms, capable of oxidising organic components of radioactive wastes (acetate, oxalate etc.) and reducing nitrate anions and transvalent radionuclides, thereby limiting distribution thereof into the geologic environment, and also selecting concentrations of aqueous solutions of carbohydrates to stimulate microbiological processes in underground conditions.

EFFECT: reduced distribution of components of radioactive wastes from burial and radioactive contamination areas.
