Waste management analysis for the nuclear fuel cycle: Parts I and II. Progress report, April 1--September 30, 1977. [Actinide recovery from waste]

Abstract

A preliminary evaluation of methods for the salt waste and waste water streams and recycle preparation problems was completed. A feasibility study for removing actinides from synthetic salt waste showed that a bidentate organophosphorus extractant is the most efficient for actinide removal. The evaluation of adsorbents for removing detergents and anions from waste water suggests the use of a combination of a non-ionic and a strong base ion exchange resin for best results.
