Symposium Resisting Degradation from the Environment: A Symposium Honoring Carolyn M. Hansson’s Research and Pioneering Experiences as a Woman in STEM
Presentation Title Evaluating the Sensitivities of SCC Susceptibility in Stainless-steel Nuclear Waste Storage Containers
Author(s) Sarah Blust, James T Burns
On-Site Speaker (Planned) Sarah Blust
Abstract Scope Used nuclear fuel (UNF) is currently stored across the US in passively cooled stainless steel dry storage canisters (DSC). Due to the design of the DSC, aerosols from the outside environment are able to deposit on the stainless-steel canisters. Over time the deposited aerosols will deliquesce on the canisters to form concentrated salt brines resulting in localized corrosion, which when coupled with the high residual stress around the welds can lead to stress corrosion cracking (SCC). The scope of the work presented is to investigate the boundaries of SCC to varying sensitivities such as environmental factors, microstructure variability, and material composition. These sensitivities will allow for recommendations to be made for canister environmental monitoring and which variables are of the greatest concern for SCC of the UNF canisters.
