METHOD OF URANIUM SEPARATION ( VI ) FROM ACTINOIDS ( IV ) AND-OR ( VI ) AND ITS USE

摘要

FIELD: physics; nuclear power.;SUBSTANCE: method of uranium separation (VI) from one or several actinoids chosen from the actinoids (IV) and the actinoids (VI) which are distinct from uranium (VI) contains the following stages: linking of organic phase not immixed with water and containing mentioned uranium and mentioned or mentioned actinoids, with the sour water solution containing, at least, one lacunar heteropolyanion and if the mentioned actinoid or, at least, one of the mentioned actinoids is actinoid (VI), the reducer capable selectively to recover this actinoid (VI); and branch of the mentioned organic phase from the mentioned water solution. Insert of the offered expedient in the first cycle of the PUREX clearing process allows refusing the second cycle of uranium tratment.;EFFECT: possibility of waiving from the second cycle of uranium treatment.;22 cl, 7 dwg, 3 ex, 3 tbl
