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.
Service and design life estimates are converging for many transmission and distribution assets. This report provides an approach to understanding the significance of reject and ranking criteria and how they may become a barrier to good asset management or a path to improving system reliability and grid resiliency.
In a previous investigation, AC corrosion rate data from weight loss experiments was compared with the results from a model for AC corrosion developed using a modified Butler-Volmer approach. In the present work, an extension of this is presented to investigate the influence of scale formation on AC corrosion rates.
