Abstract
A nuclear fuel processing solution containing (1) hydrocarbon diluent, (2) tri-n-butyl phosphate or tri-2-ethylhexyl phosphate, and (3) monobutyl phosphate, dibutyl phosphate, mono-2-ethylhexyl phosphate, di-2-ethylhexyl phosphate, or a complex formed by plutonium, uranium, or a fission product thereof with monobutyl phosphate, dibutyl phosphate, mono-2-ethylhexyl phosphate, or di-2-ethylhexyl phosphate is contacted with silica gel having alkali ions absorbed thereon to remove any one of the degradation products named in section (3) above from said solution.
Claims3
A method of processing a solution containing (1) a hydrocarbon diluent, (2) a phosphate selected from the group consisting of tri-n-butyl phosphate and tri-2-ethylhexyl phosphate, and (3) a degradation product selected from the group consisting of (a) monobutyl phosphate, (b) dibutyl phosphate, (c) mono-2-ethylhexyl phosphate, (d) di-2-ethylhexyl phosphate, and (e) a complex of plutonium, uranium, or a fission product thereof with monobutyl phosphate, dibutyl phosphate, mono-2-ethylhexyl phosphate, or di-2-ethylhexyl phosphate, comprising contacting said solution with silica gel having alkali metal ions absorbed thereon.
