Prairie Island Annual Assessment Meeting CY2008 Reactor Oversight Program Welch, MN May 13, 2009
Purpose of Todays Meeting A public forum for discussion of the licensees performance NRC will discuss 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 inform the NRC of new or existing programs to maintain or improve their performance

Who We Are The Atomic Energy Commission was established by Congress in 1946 to encourage the use of nuclear power and regulate its safety In 1974 Congress divided the AEC into two parts U.S. Nuclear Regulatory Commission Department of Energy The NRC is headed by a Chairman and four Commissioners, all appointed by the President and confirmed by the Senate for staggered five-year terms.
Vacant Commissioner Commissioner Chairman Commissioner Kristine L. Svinicki Gregory B. Jaczko Dale E. Klein Peter B. Lyons

Who We Are The NRC employs approximately 3,500 people NRC inspectors are assigned full-time to each nuclear power plant and fuel cycle facility
Who We Are The NRC Mission:
To license and regulate the nations civilian use of b
byproduct, d t source and d special i l nuclear materials to ensure adequate protection of public health and safety, promote the common defense and security, and protect the environment.
Nuclear Power Facts 104 nuclear plants at 65 sites produce approximately 20%
of U.S. electricity Nuclear electrical generation in 2007 totaled 806 billion kilowatt-hours World-wide, there are 437 nuclear plants in 30 countries (as of 2007)
Nuclear Materials Facts Nuclear materials are used in medicine for cancer treatment and diagnosis Nuclear materials are widely used in industry, such as in density gauges flow measurement gauges, devices, radiography devices and irradiators Approximately 22,000 licenses are currently issued for academic, industrial, medical, and other uses of nuclear material
Nuclear Waste Facts Nuclear fuel spends 4-6 years in the reactor until it cannot be used anymore Fuel is removed from the reactor and placed in large water pools that ensure adequate cooling and shielding After time in the pool fuel can be moved to gas-filled steel and concrete casks that continue to ensure adequate cooling and shielding If a license application is submitted, NRC would review the application and regulate a geologic repository
NRC Primary Functions Establish Rules and Regulations Evaluate license applications and issue licenses if appropriate Provide oversight through inspection of facilities, enforcement of regulatory violations, and evaluation of industry operational experience Conduct research to provide technical support for regulatory decisions Respond to events and emergencies at licensed facilities
NRC Regulatory Functions What We Regulate What We DONT Regulate Nuclear Reactors Nuclear Weapons Commercial power, research, Military Reactors test, and new reactor designs Space Vehicle Reactors Nuclear Material Naturally Occurring Radon or X-Reactor fuel, radioactive rays y
material t i l ffor medical, di l iindustrial, d ti l and academic uses These are regulated by other federal agencies Nuclear Waste Transportation, storage, disposal, and facility decommissioning Nuclear Security Facility physical security
How NRC Regulates Oversight and Inspection Full-time Resident Inspectors at each nuclear plant and fuel facility Regional Inspection Specialists Assessment Inspection results are assessed to provide a comprehensive picture of facility performance NRC adjusts dj t inspection i ti effort ff t Enforcement NRC Issues Findings and Violations Investigation of allegations of wrong-doing Emergency Response NRC Inspectors are on-call 24/7 to respond to events at any nuclear plant and fuel facility
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
Ensuring Nuclear Safety Defense-in-Depth design philosophy Safety systems must be fully independent and redundant Multiple physical barriers Routine testing of licensee Emergency Plans Ensure Compliance with Regulations and License NRC inspectors perform daily on-site inspections Reporting requirements for certain plant issues and safety data Maintenance Programs Equipment reliability, unavailability, and failures are tracked and verified Continuing Training Nuclear Plant Operators are required to undergo continuing training to retain their Operating License
Ensuring Nuclear Security 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 Intrusion detection systems and alarm stations
Reactor Oversight Process 3 Strategic Performance Areas are divided into 7 Cornerstones of Safety Inspection Findings and Performance Indicators are assigned to a Cornerstone Inspection Findings can be assigned a cross-cutting aspect (a causal factor for the issue)
Human Performance Problem Identification and Resolution Safety Conscious Work Environment Numerous findings with a common cross-cutting aspect results in a Substantive Cross-Cutting Issue

Baseline Inspections Routine inspection effort performed, as a minimum, at all reactor sites Includes daily unannounced resident inspector activities and periodic regional team inspections Over 2,000
, person-hours p of direct inspection p
effort annually Major focus areas Reactor safety Radiation safety Emergency preparedness Security
Beyond Baseline Inspections Special Inspections Inspection response to unusual or unexpected plant issues Conducted during an ongoing event or soon after Focus on the licensees evaluation and response to ongoing plant issues Supplemental Inspections Inspection response to White, Yellow, and Red inspection results and performance indicators Conducted upon completion of licensee actions to address the issue Focus on the licensees evaluation of the issue and adequacy of corrective actions
Significance Threshold Inspection Findings and Performance Indicators Green Implement Baseline Inspection program White Increasingly intrusive supplemental Yellow inspections to ensure causes are Red determined and corrected Significance Definitions Green: Very Low safety significance White: Low to Moderate safety significance Yellow:
