What We Regulate
There are two acceptable storage methods for spent fuel after it is removed from the reactor core:
- Spent Fuel Pools - Currently, most spent nuclear fuel is safely stored in specially designed pools at individual reactor sites around the country.
- Dry Cask Storage – Licensees may also store spent nuclear fuel in dry cask storage systems at independent spent fuel storage facilities (ISFSIs) at the following sites:
- At Reactor – Licensees may use dry storage systems when approaching their pool capacity limit.
- Away-From-Reactor – Licensees may use dry storage systems at one of the following locations:
- Decommissioned Reactor Sites – After terminating reactor operations and removing structures used in reactor operations, the licensee stores spent fuel on-site pending off-site transport to either a site-specific ISFSI that is authorized to receive the spent fuel, or a permanent geologic repository licensed for disposal.
- Consolidated Interim Storage Facility (CISF) – Dry cask storage at an away-from-reactor site pending disposal at a permanent disposal facility

How We Regulate
The NRC regulates spent fuel through a combination of regulatory requirements, licensing; safety and security oversight, including inspection, assessment of performance; and enforcement; operational experience evaluation; and regulatory support activities.
