Description

The corrosion/dissolution of simulated spent fuel has been studied electrochemically. Fission products within the UO2 matrix are found to have significant effect on the anodic dissolution behaviour of the fuel. It is observed that H2O2oxidation is accelerated on the surfaces of doped noble metal (ε) particles existing in the fuel matrix. It is concluded that H2O2 decomposition rather than UO2 corrosion should be the dominant reaction under high H2O2 concentrations. (author)
