Nuclear Reactors, Materials, and Waste Sector

From the power reactors that provide electricity to millions of Americans, to the medical isotopes used to treat cancer patients, America has an extensive civilian nuclear infrastructure.

Critical Infrastructure Sectors

  • Chemical Sector
  • Commercial Facilities Sector
  • Communications Sector
  • Critical Manufacturing Sector
  • Dams Sector
  • Defense Industrial Base Sector
  • Emergency Services Sector
  • Energy Sector
  • Financial Services Sector
  • Food and Agriculture Sector

  • Nuclear Reactors, Materials, and Waste Sector
  • Transportation Systems Sector
  • Water and Wastewater Sector

From the power reactors that provide electricity to millions of Americans, to the medical isotopes used to treat cancer patients, the Nuclear Reactors, Materials, and Waste Sector covers most aspects of America’s civilian nuclear infrastructure. The Nuclear Sector Risk Management Agency within the Department of Homeland Security is responsible for coordinating the security and resilience of the Nuclear Sector.

Nuclear Power Plant

Sector Overview 

The Nuclear Reactors, Materials, and Waste Sector includes:

  • 92 Active Power Reactors in 30 states that generate nearly 20 percent of the nation’s electricity. In the United States, there have been no civilian deaths associated with the operation of a nuclear power plant since the technology’s introduction over 60 years ago, making nuclear power one of the safest forms of energy in the country.
  • 31 Research and Test Reactors located at universities and national labs. These reactors produce medical and industrial isotopes used to treat cancer and perform radiographic services, as well as to conduct academic research across multiple fields, including chemistry, physics, and material science.
  • 8 Active Nuclear Fuel Cycle Facilities that are responsible for the production and reprocessing of nuclear reactor fuel. These facilities take natural uranium from the ground and enrich it to approximately 5 percent Uranium-235. This enriched uranium is turned into solid Uranium Dioxide fuel pellets for use in nuclear reactors.
  • More than 20,000 licensed users of radioactive sources. These radioactive sources are used for medical diagnostics and treatment in hospitals, depth measurements at oil and gas drilling sites, sterilization at food production facilities, research in academic institutions, and examining packages and cargo at security checkpoints.

Over 3 million yearly shipments of radioactive materials. Special security measures are taken when radioactive materials are shipped to ensure the safety of the transportation workers, and to prevent theft or sabotage of the radioactive material itself.

The sector is interdependent with other critical infrastructure sectors:

  • Chemical Sector – Chemicals are used daily in the production of electricity.
  • Emergency Services Sector – The Nuclear Sector’s uniquely hazardous characteristics require trained emergency responders during any incident.
  • Energy Sector – Nuclear facilities both supply electricity and depend heavily on uninterrupted power for continuous safe operation.
  • Healthcare and Public Health Sector – North America performs about 20 million medical procedures each year using radioactive materials.
  • Transportation Systems Sector – Nuclear and radioactive materials are shipped worldwide via air, rail, highway, and water.
  • Water and Wastewater Systems Sector – Nuclear power plants use large quantities of water for cooling. Interrupted water supply may require shut down.

Sector-Specific Plan

The Nuclear Reactors, Materials, and Waste Sector-Specific Plan details how the National Infrastructure Protection Plan's risk management framework is implemented within the context of the unique characteristics and risk landscape of the sector. Each Sector Risk Management Agency (SRMA) develops a sector-specific plan through a coordinated effort involving its public and private sector partners. The Department of Homeland Security is designated as the SRMA for the Nuclear Reactors, Materials, and Waste Sector.

Nuclear Sector Cybersecurity Framework Implementation Guidance

The National Institute of Standards and Technology (NIST) released the voluntary Framework for Improving Critical Infrastructure Cybersecurity (Framework) in February 2014 to provide a common language that critical infrastructure organizations can use to assess and manage their cybersecurity risk. The Framework enables an organization—regardless of its sector, size, degree of risk, or cybersecurity sophistication—to apply the principles and effective practices of cyber risk management to improve the security and resilience of its critical infrastructure.

The U.S. Department of Homeland Security (DHS), as the Sector Risk Management Agency (SRMA), worked with the Nuclear Reactors, Materials, and Waste Resources Sector Coordinating Council (SCC) and Government Coordinating Council (GCC) to develop the Nuclear Sector Cybersecurity Framework Implementation Guidance specifically for Nuclear Sector owners and operators. This Implementation Guidance provides Nuclear Sector organizations with:

  • Background on the Framework terminology, concepts, and benefits of its use.
  • A mapping of existing cybersecurity tools and resources used in the Nuclear Sector that can support Framework implementation.
  • Detailed Framework implementation steps tailored for Nuclear Sector owners and operators.
