The electrochemical corrosion potential (ECP) of stainless steel has been measured under simulated Boiling Water Reactor (BWR) coolant circuit conditions using a rotating cylinder electrode. Based on the results of measurements an empirical model has been developed to predict the ECP of structure materials in a BVTR primary circuit as a function of H{sub 2}, O{sub 2}, and H{sub 2}O{sub 2} concentrations in reactor coolant and water flow velocity. The ECP modeling results using the H{sub 2}, O{sub 2}, and H{sub 2}O{sub 2} concentrations calculated by the radiolysis model are compared with the available reactor internal ECP data obtained in an operating reactor.
