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.

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.

Holtec’s HI-SAFE storage system provides an extremely safe and cost effective solution for on-site storage of non-fuel waste generated from operation and decommissioning of commercial nuclear power plants.

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. The heat generated by a loaded spent fuel cask is typically less than is given off by a home ...

2024年10月7日 · What is dry cask storage? Dry cask storage allows spent fuel that has already been cooled in the spent fuel pool for several years to be surrounded by inert gas inside a container called a cask. The casks are typically steel cylinders that …

Dry cask storage is safe and environmentally sound. 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. The heat generated by a loaded spent fuel cask is typically less than is given off by a home-heating ...

The dry cask storage is less prone to catastrophes. Different from spent fuel pool, dry casks exploits passive cooling by natural convection that is driven by the decay heat of the spent fuel itself. In other words, dry cask is not vulnerable to loss of coolant, which, in comparison, will result in cascade of accidents in spent fuel pool.

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).

An underground dry cask storage facility has been proposed at the Humbolt Bay power plant in California to store old, low decay-heat fuel. The underground design is being proposed primarily because the site has very demanding seismic design requirements and is possible only because the fuel to be stored generates little heat.

The purpose of this report is to research and document the dry storage design criteria for the cask systems currently storing or planned for storage of UNF and GTCC at from permanently shutdown reactor sites by 2019.
