1Davis-Besse Nuclear Power Plant Annual Assessment Meeting/Open HouseReactor Oversight Process -2012Nuclear Regulatory Commission -Region III Lisle, IllinoisJune 11, 2013 2 Purpose of Today's Meeting*A public forum for discussion of Davis-Besse Nuclear Power Plant's

performance in 2012*NRC personnel will be available to answer questions on NRC activities and identified licensee performance

issues 2 3 Our Mission To license and regulate the nation's 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.

4 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.

3 5 Some Nuclear Facts*102 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.

6The 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 4 7What We Do -Nuclear WasteThe NRC regulates:-Storage of spent reactor fuel in fuel pools or dry

storage casks, and-Any national spent fuel storage

site.8What 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.

5 9What We Don'tDo*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 10 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 6 11Assurance of Plant Safety*Require "defense-in-depth"*Require long-term maintenance of equipment*Require continual training of operators*Verify compliance with regulations 12 Reactor Oversight ProcessSafetyCornerstonesBaseline Inspection ResultsSignificance ThresholdAction MatrixSignificance ThresholdPerformance IndicatorResultsRegulatory ResponseStrategicPerformance AreasSafetyCornerstonesBaseline Inspection ResultsSignificance ThresholdAction MatrixSignificance ThresholdPerformance IndicatorResultsRegulatory ResponseStrategicPerformance Areas 7 13Action Matrix ConceptIncreasing Safety SignificanceIncreasing NRC Inspection Efforts Increasing NRC/Licensee Management Involvement Increasing Regulatory ActionsLicenseeResponseRegulatoryResponseDegradedCornerstoneMultiple/Rep.DegradedCornerstoneUnacceptablePerformance 14Examples of Baseline Inspections*Equipment Alignment ~80 hrs/yr *Triennial Fire Protection ~250 hrs every 3 yrs*Operator Response ~125 hrs/yr

This includes the following team inspections:Triennial Fire Protection (completed In

March)Graded Emergency Plan Exercise (conducted in May)Biennial Problem Identification and

Resolution Initial review of Steam Generator

Replacement Activities NRC Security Inspection Plans 2013On August 10, 2012, NRC identified one or more "greater-than-green"/blue Security Cornerstone inputs NRC will follow Reactor Oversight Process Action Matrix for plants in

Regulatory Response ColumnSecurity Inspection Plans were discussed with licensee at a non-public

meeting 24 13 25 Open to the Public*The NRC places a high priority on keeping the public and stakeholders informed of its

activities. *At www.nrc.gov, you can:-Find public meeting dates and transcripts;-Read NRC testimony, speeches, press releases, and policy decisions; and -Access the agency's Electronic Reading Room to find NRC publications and documents.
