Abstract: AWD-1. A one-cycle solvent-extraction flowsheet was used to separate U/sup 233/ from fission products and other contaminants contained in the raffinate. The U/sup 233/ was extracted into 6% tributyl phosphate in Amsco 125-82 and subsequently stripped into dilute HNO/sub 3/. Feed for rum AWD-1 was prepared by concentrating amd adjusting the 1A-column raffinate from run HD-19 to feed specifications. (auth)
