In operando SEM imaging of electrochemical oxidation of uranium oxide (UO2) will be presented in this contribution. Specifically the electrochemical version of the System for Analysis at the Liquid Vacuum Interface (SALVI) was used to study the interaction of dissolved oxygen, hydrogen peroxide and hydrogen with UO2. The Quanta 250 FEG SEM housed in the Radiological Processing Laboratory (RPL) was used to for experiments of radiological materials. In operando results and the application of in situ SEM imaging in studying nuclear materials will be presented.
