Laboratory Development of the Acid Thorex Process for Recovery of Consolidated Edison Thorium Reactor Fuel

Description: The id Thorex process, in which nitric acid is the salting'' agent in the solvent extraction of Th and U from an acid eficient feed with TBP in Amsco, was demonstrated in laboratory equipment for the recovery of synthetic Co solidated Edison Thorium Reactor fuel containing trace fission products. The acid was removed from solution of the declad fuel pellets to produce an acid deficient feed by steam stripping, and the adjusted feed was treated with bisulfite to decrease the extractability of fi… more

Extraction of Niobium-95 From Nitric Acid Solutions With Tri-N-Butyl Phosphate

Description: The distribution coefficient (DC o/a) of Nb/sup 95/ between aqueous nitric acid and 30% Tri-n-butyl phosphate (TBP) in n-dodecane increased from ~0.004 to O.1 N acid deficient solution to 0.05 in 4 M HNO/sub 3/ for the extractable portion of the niobium. Greater than 70% of the niobium was unextractable. The presence of 3% chemically degraded TBP, 7% chemically degraded Amsco, or both decreased the amount of unextractable niobium to <20% and degraded TBP increased the distribution of the extrac… more
