Our Mission

  • To license and regulate the nations civilian use of byproduct, source, and special nuclear materials to ensure adequate protection of public health and safety, promote the common defense and security, and protect the environment.

5

Some Nuclear Facts

  • 104 nuclear power plants supply about 20 percent of the electricity in the U.S.
  • Nuclear materials are used in medicine for diagnosis and cancer treatment.
  • Nuclear materials are widely used in industry, such as in density gauges, gauges flow measurement devices, radiography devices, and irradiators.

6

The NRC Regulates g

  • Nuclear reactors - commercial power reactors reactors, research and test reactors, new reactor designs
  • Nuclear materials - nuclear reactor fuel fuel, radioactive materials for medical, industrial, and academic use
  • Nuclear waste - transportation, transportation storage and disposal of nuclear material and waste, decommissioning of nuclear facilities
  • Nuclear security - physical security of nuclear facilities and materials from sabotage or attacks 7

What We Dont Do

  • R Regulate l t nuclear l weapons, military ilit reactors, or space vehicle reactors
  • Own or operate p nuclear power p plants p
  • Regulate some radioactive materials materials, such as X-rays and naturally occurring radon 8

How We Regulate g

  • Establish rules and regulations
  • Issue licenses
  • Provide P id oversight i ht th throughh inspection, i ti enforcement, and evaluation of operational experience
  • Conduct research to provide support for regulatory decisions
  • Respond to events and emergencies 9

Assurance of Plant Safety y

  • RRequire i defense-in-depth d f i d th
  • Require long-term maintenance of equipment
  • Require q continual training g of operators
  • Verify compliance with regulations 10

What We Do - Nuclear Waste

  • The NRC regulates:

- Storage of spent reactor fuel in fuel pools or dry storage casks, and

- Any national spent fuel storage site.

11

What We Do - Nuclear Security y

  • NRC Requires:

- Well-armed and well-trained security forces,

- Surveillance and perimeter patrols,

- State-of-the-art site access equipment and controls,

- Physical barriers and detection zones, and

- Intrusion detection systems and alarm stations.

12

NRC Performance Goals

  • SSafety:

f t Ensure E adequate d t protection t ti off public health and safety and the environment.

i t

  • Security: Ensure adequate protection g

in the secure use and management of radioactive materials.
