Dry cask storage is a method of storing high-level radioactive waste, such as spent nuclear fuel that has already been cooled in a spent fuel pool for at least one year and often as much as ten years.

2023年6月16日 · Dry cask storage allows spent fuel that has already been cooled in the spent fuel pool for at least one year to be surrounded by inert gas inside a container called a cask. The casks are typically steel cylinders that are either welded or bolted closed. The steel cylinder provides a leak-tight confinement of the spent fuel.

2023年6月12日 · Dry cask storage is safe for people and the environment. Cask systems are designed to contain radiation, manage heat and prevent nuclear fission. They must resist earthquakes, projectiles, tornadoes, floods, temperature extremes and other scenarios.

Orano TN is an expert manufacturer and service provider of NRC-licensed packages (canisters, casks, cylinders) for managing, storing, and transporting radioactive materials. Canisters and cylinders are used to contain nuclear material. Casks are used to …

Bolted casks have thick steel shells, sometimes with several inches of radiation shielding inside. Plants use special transporters to move the loaded cask outdoors to where it will be stored. At that point, the radioactivity from the cask must be less than 25 millirem per year at the site boundary.

Conceived in 1992, HI-STAR 100 is the nuclear industry’s first high-capacity, multi-purpose canister (MPC) technology-based system which is equally proficient at storing the spent nuclear fuel on an ISFSI pad, or at transporting its highly radioactive payload over land or water.

2021年9月15日 · To design and build a reliable dry storage cask that can provide efficient storage for these radioactive hazardous materials some considerations must be achieved. Safe enclosure of the spent nuclear fuel rods besides adequate radiation shielding and protection against all possible kinds of hazardous radiation must be insured over long periods.

It is often highly radioactive and it generates huge amount of decay heat as a result of beta decay of fissile products, although the fissile chain reaction has ceased. Quantitatively, spent fuel, five minutes after reactor shutdown, still releases about 800 …

Some advantages of the dry cask storage system include the mobility of the casks and its safety against earthquakes. The casks are not fixed to the ground, so if it needs to be relocated, it can be easily moved, making the cask a dual-purpose system (transportation and storage).
