METHOD FOR BURIAL OF SPENT ORGANIC RADIOACTIVE EXTRACTANT.

FIELD: physics, nuclear physics.

SUBSTANCE: invention is related to methods for burial of liquid radioactive wastes, namely, spent extractant - tributyl phosphate in hexachlorobutadiene, into deeply seated
underground reservoir beds. Method for burial of spent radioactive extractant includes its emulsification by carbonate-alkaline wastes produced at the stage of extractant regeneration, with addition of sodium oleate or its mixture with isoamyl and/or isobutyl alcohol at the following ratio of components: tributyl phosphate in hexachlorobutadiene, vol. part 1 carbonatealkaline wastes, vol. part 19 sodium oleate, g/l of carbonate alkaline wastes 100 or tributyl phosphate in hexachlorobutadiene, vol. part 1
carbonate-alkaline wastes, vol. part 9 sodium oleate, g/l of carbonate-alkaline wastes 100 isoamyl and/or isobutyl alcohol, vol. part 0.3.
Prepared emulsion is forced via well into deep reservoir bed, which has been previously prepared by injection of carbonate-alkaline wastes, with further edging of emulsion from well head by carbonate-alkaline wastes.

EFFECT: provision of efficient and profitproved removal of radioactive organic wastes from biological human environment. 1 cl, 4 tbl
