6 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, flow measurement devices, radiography devices, and irradiators.

7 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.

8 Assurance of Nuclear Plant Safety

• Require defense-in-depth

• Require long-term maintenance of equipment

• Require continual training of operators

• Verify compliance with regulations

9 What NRC Regulates

• Nuclear reactors - commercial power reactors, research and test reactors, new reactor designs

• Nuclear materials - nuclear reactor fuel, radioactive materials for medical, industrial, and academic use

• Nuclear waste - 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

10 How NRC Regulates

• Establish rules and regulations

• Issue licenses

• Provide oversight through inspection, enforcement, and evaluation of operational experience

• Conduct research to provide support for regulatory decisions

• Respond to events and emergencies

11 What We Do - Nuclear Waste NRC regulates:

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

- Any national spent fuel storage site or reprocessing facility

12 What We Do - Nuclear Security 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.

13 NRC Performance Goals

• Safety: Ensure adequate protection of public health and safety and protect the environment.

• Security: Ensure adequate protection in the secure use and management of radioactive materials.

Protecting People and the E,w;ronment

14 What NRC Doesnt Do

• Regulate nuclear weapons, military reactors, or space vehicle reactors

• Own or operate nuclear power plants

• Regulate some radioactive materials, such as X-rays and naturally occurring radon
