Byron Station Annual Assessment Meeting Reactor Oversight Program - 2008 Nuclear Regulatory Commission - Region III Lisle, Illinois April 2, 2009

2 Purpose of Todays Meeting

  • A public forum for discussion of the licensees performance in 2008
  • NRC will address the performance issues identified in the annual assessment letter
  • Licensee will be given the opportunity to respond and inform the NRC of new or existing programs to maintain or improve performance

3 Agenda

  • Introduction
  • Review of Reactor Oversight Process
  • National Summary of Plant Performance
  • Discussion of Plant Performance Results
  • Licensee Response and Remarks
  • NRC Closing Remarks
  • Break
  • NRC available to address public questions

4 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

  • More than 100 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.

6 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
  • 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

7 What We Dont 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

8 How We Regulate

  • 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

9 Assurance of Plant Safety

  • Require defense-in-depth
  • Require long-term maintenance of equipment
  • Require continual training 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

- A national spent fuel storage site--Yucca Mountain.

11 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.

12 NRC Performance Goals

  • Safety: Ensure adequate protection of public health and safety and the environment.
  • Security: Ensure adequate protection in the secure use and management of radioactive materials.
