Hybrid Extraction Process For Separation Of Americium From Trivalent Lantanides

Technology Benefits

The bulk organic solvent is protected from the aggressive oxidizing aqueous solution the residence time that the oxidized americium spends in the organic phase is reduced.

Technology Application

Nuclear fuel processes

Detailed Technology Description

The oxidation of americium in spent nuclear fuel is not new but the problem is that the higher oxidation states of americium tend to degrade the chemicals used for liquid extraction. Thus the combination of oxidation of Am with liquid extraction is problematic. UCI researchers have developed a process combining oxidation of Am from +3 to a higher oxidation state of +4 or +6 followed by selective extraction through a membrane with the general idea being to use an extraction membrane where the bulk of the organic solution is protected from the oxidizing environment.
