Pyroredox. This is a three-step plutonium purification process ( 3). Impure plutonium metal is reacted with ZnCl2 in a solvent salt of KC1-CaCl 2 > as follows ... 

Pyroredox is currently under development. Several problems have been identified and work is underway to overcome these obstacles. As mentioned previously, this process has immediate application as a primary plutonium purification process and as a means to process spent electrorefining anodes for direct recycle back to electrorefining. 

After a study of the three alternatives we concluded that pyroredox offered the most promise for anode residue recovery. Pyroredox is a molten-salt process in which plutonium metal is oxidized chemically into the salt phase and then reduced chemically into the metal phase. Most of the impurities are not oxidized and remain in the metal residue. Thus, for a Pu-Ga anode residual, the reactions would be ...
