Electrodes of natural UO(2) have been electrochemically tested in various aerated and deaerated 3%Na(2)CO(3) and other solutions. UO(2) rapidly takes up dissolved oxygen to form UO(2+x) of corresponding rest potential. UO(2) oxidises in several stages; the rate of oxidation rises with increasing (anodic) potentials. The attack and redeposition of corrosion products on the electrode appears to be localised.
