Oliver, J. R.

Laboratory studies indicated that a Thorex third cycle uranyl nitrate feed containing 50 g of uranium per liter should be 0.70 M in Al(NO/sub 3/)/sub 3/ and 0.50 M in HNO/sub 3/ scrub, 0.50 M in Al(NO/sub 3/)/sub 3/: the extractant, 10 vol. % tributyl phosphate (TBP) in Amsco; and the feed/scrub/extractant flow ratios, 1/0 3/1,5, With these conditions the uranium loss was 0.005 g/liter, or 0.01%, in laboratory tests. Decontamination factors were about 600 for ruthenium and 400 for zirconium--niobium. (auth)
