Joseph M. Farley Nuclear Plant Purpose of Todays Meeting Annual Assessment Meeting Reactor Oversight Program - CY 2008 A public forum for discussion of the licensee licensees performance NRC will address the licensee performance issues identified in the annual assessment letter Licensee will be given the opportunity to respond to the information in the letter and Nuclear Regulatory Commission - Region II inform the NRC of new or existing programs to Dothan, AL maintain or improve their performance March 19, 2009 Agenda Region II Organization Luis Reyes Regional Administrator Victor McCree Introduction Deputy Regional Administrator Review of Reactor Oversight Process National Summary of Plant Performance Division of Reactor Projects Len Wert, Director Division of Reactor Safety Kriss Kennedy, Director Richard Croteau, Deputy Director Joel Munday, Acting Deputy Director Discussion of Plant Performance Results Harold Christensen, Deputy Director Licensee Response and Remarks NRC Closing Remarks Projects Branch 2 Scott Shaeffer, Chief (404)562-4521 Regional Specialist Inspectors Break NRC available to address public questions Resident Inspectors (RI)

Our Mission Some Nuclear Facts To license and More than 100 nuclear regulate the nation nations power plants supply about 20 percent of the civilian use of electricity in the U.S.

byproduct, source, and special nuclear Nuclear materials are used materials to ensure in medicine for diagnosis and cancer treatment.

adequate protection of public health and Nuclear materials are safety, promote the widely used in industry, common defense and such as in density gauges, security, and protect flow measurement devices, radiography devices, and the environment. irradiators.

The NRC Regulates What We Dont Do Nuclear reactors - commercial power reactors, Regulate nuclear weapons, military research and test reactors, new reactor designs reactors, or space vehicle reactors Nuclear materials - nuclear reactor fuel, radioactive materials for medical, industrial, and academic use Own or operate nuclear power plants Nuclear waste - transportation, storage and disposal of nuclear material and waste, Regulate some radioactive materials, decommissioning of nuclear facilities such as X-X-rays and naturally Nuclear security - physical security of nuclear occurring radon facilities and materials from sabotage or attacks

How We Regulate Assurance of Plant Safety Establish rules and regulations Require defense-defense-in-in-depth depth Issue licenses Provide oversight through inspection, Require long-long-term maintenance of enforcement, and evaluation of equipment operational experience Conduct research to provide support Require continual training of for regulatory decisions operators Respond to events and emergencies Verify compliance with regulations What We Do - Nuclear Waste What We Do - Nuclear Security The NRC regulates: NRC Requires:

  • Well-Well-armed and well-well-
  • Storage of spent trained security forces, reactor fuel in fuel
  • Surveillance and pools or dry storage perimeter patrols, casks, and
  • State-State-of-of-the-the-art site access equipment and controls,
  • A national spent
  • Physical barriers and fuel storage site--

  • Intrusion detection systems and alarm stations.

2008 Assessment Summary Overall Assessment Impact Overall, Farley Farleys performance has improved over the assessment period Southern Nuclear operated Farley in a manner that preserved public health and Both units improved their standing on the NRC NRCs Action Matrix safety with moderate degradation in safety All NRC Supplemental inspections conducted during 2008 were successfully completed with no new significant regulatory issues being performance identified.

All cornerstone objectives were met Specific corrective actions associated with breakers, EDGs and RHR sump valves have been effective For the remainder of 2009: Programmatic corrective actions in the area of root cause evaluations evaluations NRC plans baseline inspections and corrective action program improvements have been implemented.

implemented.

Although all effectiveness reviews have not been completed, the NRC will be looking for sustained performance in the areas noted above.
