Book Description
A process was developed for recovering 241Am from aged plutonium oxide. The oxide is dissolved with nitric acid and fluoride, the fluoride is complexed with aluminum, and plutonium and americium are separated by one cycle of solvent extraction. Americium is concentrated and purified by cation exchange chromatography and precipitated as oxalate. The process was successfully operated in Savannah River Plant facilities to recover approximately 720 g of 241Am from about 60 kg of aged plutonium oxide.
