An alternative method for directly measuring effectiveness of AC-induced corrosion control and mitigation efforts. This method takes the form of traditional coupons imbedded with ultrasound testing (UT) transducers designed to directly measure and track coupon metal loss and related corrosion-induced anomalies.
Nuclear wastes are stored in large, underground carbon-steel storage tanks at the Hanford site. Carbon steels can become susceptible to localized corrosion. This paper presents the results of ongoing electrochemical investigations to understand the reasons behind the noble drift in the OCP of carbon steel in these waste simulants.
