Our Mission

nuclear materials to ensure adequate protection of public health and safety, promote the common defense and security, and protect the environment.

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 6

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.

The 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 7
  • 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

What We Dont Do

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

How We Regulate

  • Establish rules and regulations
  • Issue licenses
  • Provide oversight through inspection, f

t d

l ti f

9 enforcement, and evaluation of operational experience

  • Conduct research to provide support for regulatory decisions
  • Respond to events and emergencies

Assurance of Plant Safety

  • Require defense-in-depth
  • Require long-term maintenance of equipment 10
  • Require continual training of operators
  • Verify compliance with regulations

What We Do - Nuclear Waste

  • The NRC regulates:

- Storage of spent reactor fuel in fuel pools or dry storage casks and 11 casks, and

- Any national spent fuel storage site, such as the proposed Yucca Mountain site.

What We Do - Nuclear Security

  • NRC Requires:

- Well-armed and well-trained security forces,

- Surveillance and perimeter patrols, 12 perimeter patrols,

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

controls,

- Physical barriers and detection zones, and

- Intrusion detection systems and alarm stations.

NRC Performance Goals

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

13

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

Byron Assessment Results January 1 - December 31, 2009 Byron Units 1 and 2 were within the Licensee Response column for the last three quarters of 2009.

20 Byron Units 1 and 2 were within the Regulatory Response column for the first quarter of 2009 due to a White Finding in the Mitigating Systems Cornerstone identified in the first quarter of 2008.

The White Finding was related to the Essential Service Water piping degradation.

The supplemental inspection for the White finding was completed in January of 2009 with no finding.

Safety Significant Findings or PIs January 1 - December 31, 2009

  • All inspection findings were of very low safety significance 21 low safety significance.
  • All performance indicators required no additional NRC oversight.
