Nickel Alloys, stainless steel & Titanium Canisters

The metal canisters that will hold the spent fuel or other high-level nuclear waste form part of barrier system; the canisters directly protect the waste from mechani­cal impact, exposure to the chemical environment, and contact with fluids. One of the key decisions then, to ensure the canister’s usefulness as a barrier, is the choice of material used. One of the most common is highly corrosion-resistant nickel-chromium-molybdenum (Ni-Cr-Mo) alloys which are very stable in the deep underground environment. These alloys also have high strength and are readily fabricable by conventional methods.
