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.

Americium processing a t Rocky Flats Plant is described. The ameri cium is recovered from plutonium metal by a pyrochemical proce ss ; the resulting molten salt extraction residues must be proces sed to recover americium. At present the process uses cation exchange with Dowe x SOW-X8 resin. Thi s work shows that a macroporous resin, BioRad AG MP-50, has 30 to 50% more capacity and better elution kinetics than Dowex 50W-X8. Two extraction methods, solvent extract ion and extraction chromatography with an organophosho r us bldentate, a re also desc r ibed. Americium is effective l y decontam in ated fr om magnesium and aluminum, and recove red by t he se me t hods.
