The Effluent Treatment Facility (ETF) at the Hanford nuclear-waste storage facility is a waste treatment
facility permitted under the Resource Conservation and Recovery Act of 1976 (RCRA). The facility removes radioactive and hazardous contaminants from various sources such as condensate wastewater
generated by 242-A Evaporator campaigns, groundwater projects, solid waste disposal facilities, and
other Hanford clean-up activities. The waste processed by the ETF is substantially more dilute than the
waste stored in the tanks.

Performing Corrosion Risks Assessments of Nuclear Waste Process Tanks Containing Variable Waste Chemistries

Product Number: 51323-18878-SG

Author: J.S. Page, S.T. Campbell, C.L. Girardot, J.R. Gunter

Publication Date: 2023

$20.00

The Hanford Site stores over 50 million gallons (190 million liters) of legacy nuclear process waste that was generated from plutonium separations and waste management processes. This waste, in the form of supernatant liquids, saltcakes, and sludges is contained in large underground storage tanks, up to a million gallons (3.78 million liters) in capacity and lined with carbon steel. The waste was made highly alkaline to ensure passivation of the carbon steel, but it also contains nitrate, in high concentrations, along with fluoride and chloride that poses risks for stress corrosion cracking and pitting corrosion.

Review Of Techniques To Evaluate SCC Susceptibility Of Carbon Steels Used In Construction Of Nuclear Waste Tanks

Product Number: 51322-18062-SG

Author: B.C. Rollins, S. Chawla, J. Gerst, J.A. Beavers, J. Page, C. Girardot, S. Campbell, N. Sridhar

Publication Date: 2022

$20.00

The Hanford Nuclear Reservation contains radioactive and chemically hazardous wastes arising mostly from weapons production, beginning with World War II and continuing through the Cold War. The wastes are stored in 177 carbon steel underground storage tanks, of which 149 are single-shell tanks (SSTs) and the remaining are double-shell tanks (DSTs). The U.S. Department of Energy, Office of River Protection is responsible for retrieving the tank wastes, treating them in order to encapsulate them in glass logs, and then permanently closing the tanks and associated facilities.

SCC Susceptibility Potential Range for Carbon Steels Used in Nuclear Waste Tanks Determined with a Crack Growth Rate Technique

Product Number: 51324-21154-SG

Author: B.C. Rollins; S. Chawla; J.S. Page; C.L. Girardot; S.T. Campbell

Publication Date: 2024

Stress corrosion cracking (SCC) is a documented threat to the integrity of carbon steel radioactive waste storage tanks at the Hanford Nuclear Reservation. A previously published study compared the slow strain rate (SSR) test technique to three alternative SSR methods. That study showed that, regardless of the technique employed, inconclusive results due to subjective aspects of the post-test evaluation are possible. Additionally, the study suggested that the crack growth rate (CGR) technique might reduce ambiguity and more accurately define the critical cracking potential (CCP). The focus of the current study was determining the potential window of SCC susceptibility using the CGR technique as compared to multiple SSR techniques. The results of the study showed the minimum applied potential required to sustain cracking was dependent on whether intergranular SCC was already established. A more noble potential was required to activate intergranular SCC than it was to maintain cracking.
