Dry cask storage

Dry cask storage is a method used to safely store used nuclear fuel after it has been cooled in a spent fuel pool. The spent fuel is sealed in large, robust metal cylinders called casks, which are often made of steel and concrete. These casks provide shielding from radiation, prevent leaks, and protect against environmental factors like weather and natural disasters. They are stored on-site at nuclear power plants or in specialized facilities. Dry cask storage is a secure, passive means of containing radioactive material, allowing for safe, long-term management until the fuel can be further processed or permanently disposed of.
