The Hanford site contains approximately 55 million gallons of radioactive and chemically hazardous wastes arising from weapons production. This paper will present a Bayesian framework to model the probability of tank failures at Hanford and illustrate its use for tanks that are already known to have failed and leaked waste.
The Hanford Site in Richland, WA stores liquid radioactive waste in underground, carbon steel tanks. Electrochemical corrosion testing was performed to determine new limits that optimize the chemistry control, yet are robust enough to inhibit against the possibility of increased concentrations of aggressive species.
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.
