CX-270431: Identifying, Predicting, and Preventing Localized Corrosion in Kr-85 Storage Canisters – The University of Virginia

The University of Virginia, in collaboration with Pacific Northwest National Laboratory (PNNL), proposes to elucidate the controlling mechanisms of the extensive corrosion within the Kr storage canisters. Three key issues associated with the role of Rb in the localized corrosion processes will be resolved: 1) to investigate the chemical species that were, or could have been present in the container to determine the likelihood that Rb was present in the metallic or ionic state; 2) to investigate the nature of the interaction between metallic Rb and steel and 3) to investigate the corrosion of steel in the presence of Rb+ ions and other likely species in the presence of water.
