- W62979670 abstract "Plutoniumn metal has been produced in kilogram quantities in remotely controlled equipment at the Los Alamos Scientific Laboratory since 1951. The chemistry consists of peroxide precipitation of plutonium from a nitrate feed solution, conversion of the peroxide to plutonium tetrafluoride, and reduction of the tetrafluoride to plutonium metal. The aqueous chemistry is performed is a flass reaction vessel. Solid plutonium peroxide is separated from the supernatant liquid by filtering through a sintered platinum disc, Direct conversion to plutonium tetrafluoride is accomplished by passing anhydrous hydrogen fluoride through the peroxide cake. The tetrafluoride powder is then mixed with calcium, poured into a ceramic crucible and reduced to carried out on a batch basis. The unitt consists primarily of an enclosed horizontal conveyor, which transports the plutonium between chemical processing stations, and pneumatic cylinders, for vertical transmission into each processing station. Incorporated in the design are features which exclude all accessory equipment from the contaminated enclosure. Each processing station is cements - can be made simply without spread of contamination Manual servicing of the unit requires loading of the plutonium nitrate container, crucible and gasket, extraction of the plutomium pellet and residues, and maintaining reagent supplies.
