Spent nuclear fuel is stored either in spent fuel pools (SFPs) or in dry casks. In the United States, SFPs and casks containing spent fuel are located either directly on nuclear power plant sites or on Independent Spent Fuel Storage Installations (ISFSIs).
Where is most nuclear spent fuel stored?
The second approach stores pre-cooled spent fuel rods in a container filled with inert gas. Each container is surrounded by steel, concrete, or other material to provide a stronger shield from radiation. In the United States, nearly all spent nuclear fuel is currently stored onsite at commercial nuclear power plants.
What are 2 ways that spent fuel can be stored?
There are two storage methods used for spent fuel: spent fuel pools and dry cask storage.
Where is spent nuclear energy stored?
from the reactor following power production are called spent nuclear fuel. SNF is stored in one of two ways: in wet storage pools and in dry casks. Immediately following power production, SNF is discharged from the reactors and stored in wet storage pools on site, as it remains intensely radioactive and thermally hot.
Where is spent uranium stored?
Spent Fuel Pools – Currently, most spent nuclear fuel is safely stored in specially designed pools at individual reactor sites around the country.
Can nuclear waste be reused?
Used nuclear fuel can be recycled to make new fuel and byproducts. More than 90% of its potential energy still remains in the fuel, even after five years of operation in a reactor.
How is spent nuclear fuel recycled?
For recycling, spent nuclear fuel is fed into a chemical processing system that separates actinide elements that can be recycled as mixed-oxide fuel to produce more electrical power. At PNNL, this research is done in the Radiochemical Processing Laboratory, a Hazard Category II non-reactor nuclear research facility.
What is in spent nuclear fuel?
About 95% of the spent fuel is still uranium-238, which can be used again. The other compounds that now exist in the fuel are heavy isotopes (plutonium, americium, neptunium and curium) and other products of fission. Because uranium exists in this waste, it can be used in fast reactors as a fuel.
What is done with spent nuclear fuel?
For recycling, spent nuclear fuel is fed into a chemical processing system that separates actinide elements that can be recycled as mixed-oxide fuel to produce more electrical power. At PNNL, this research is done in the Radiochemical Processing Laboratory, a Hazard Category II non-reactor nuclear research facility.
How is uranium stored?
Depleted uranium is primarily stored at the enrichment facilities in the form of uranium hexafluoride (UF6), a chemical form required for enrichment but not optimal for long-term storage. This depleted uranium hexafluoride (DUF6) is typically stored in 14-ton cylinders near the enrichment facilities.
