Enhancing the electrocatalytic properties of wetted surfaces is a very effective means of mitigating SCC in oxidizing environments such as in BWRs, provided there is a stoichiometric excess of reductants over oxidants. The mechanisms and criteria for effective SCC mitigation are summarized, with particular focus on the critical location for the catalyst.
