Nuclear power accounts for approximately 20 percent of our nation’s electrical generation, provided by 100 commercial nuclear reactors licensed to operate at 62 nuclear power plants.

The sector includes:

• Nuclear power plants
• Non-power nuclear reactors used for research, testing, and training
• Manufacturers of nuclear reactors or components
• Radioactive materials used primarily in medical, industrial, and academic settings
• Nuclear fuel cycle facilities
• Decommissioned nuclear power reactors
• Transportation, storage, and disposal of nuclear and radioactive waste

The sector is interdependent with other critical infrastructure sectors:

• Chemical Sector, as a consumer of chemicals through the nuclear fuel cycle and at reactor sites
• Energy Sector, as a supplier of electricity to our nation’s electrical grid
• Healthcare and Public Health Sector, as a supplier of nuclear medicine, radiopharmaceuticals, and in the sterilization of blood and surgical supplies
• Transportation Systems Sector, through the movement of radioactive materials.
