Dry cask storage is a technique for processing high-level hazardous waste, such as spent nuclear fuel, which has been stored in the spent fuel tank for at least a year and sometimes as long as ten years. Usually, casks are made from concrete and metal tubes and are either welded or locked. Inside, fuel rods are encircled by inert gas. The tanks provide leak-tight protection. The cylinder is covered by extra steel, concrete, or other material to provide radiation shielding.
