Corrosion-Resistant Metallic Canisters for Nuclear Waste Isolation
A program with the goal of estimating the potential of a material to survive 300 years as a nuclear waste canister is underway at Sandia Laboratories. The corrosion and stress corrosion cracking behavior of the leading candidate, TiCode-12***, is contrasted to that of a commonly used engineering alloy, 304 stainless steel. Experimental evidence is presented which shows the inadequacy of 304 stainless steel in potential repository environments and shows that TiCode-12 could endure the desired 300 years. Further work required to qualify TiCode-12 is outlined.
