Data Report on Corrosion Testing of Stainless Steel SNF Storage Canisters

The report assesses the localized corrosion performance of container/cask materials used in the interim storage of used nuclear fuel. A detailed evaluation of the storage system environment, including uncertainties in temperature, humidity, and sea and continental salt occurrence is provided, and the potential impacts on corrosion are discussed.  Initial results from a sampling program of in situ dust deposits on in-service storage canisters are provided.  The results of dust deliquescence testing, to evaluate potential stifling of corrosion due the limited mass of the deposited salts, are presented.
