Purpose of Todays Meeting

• A public forum for discussion of the licensees performance in 2011

• 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 2

Agenda

RIII ORGANIZATION 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

• 104 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, f t andd evaluation l ti off 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 casks,

- Any national spent fuel storage site 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

- 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 13

Safety Significant Findings or PIs

• The NRC identified one finding of moderate safety significance and twenty findings of low safety significance in 2011.

• The White finding was due to a design issue which impacted the way the Unit 1 safety related battery chargers operated during specific plant events.

• The Unit 1 performance indicators remained green throughout 2011 21

Prairie Island Unit 1 January 1 - December 31, 2011

• Unit 1 operated in the Licensee Response Column for the 1st quarter of the assessment period

• Unit 1 operated in the Regulatory Response Column for the remaining 3 quarters of 2011, based upon the White finding for the battery chargers

• A supplemental inspection for the White finding was completed in February 2012.

22

Prairie Island Unit 2 January 1 - December 31, 2011

• Unit 2 operated in the Licensee Response C l Column d due to t all ll findings fi di and d performance f

indicators being assessed as Green.

• There were no supplemental inspections for Unit 2 during the assessment period 23

Prairie Island Units 1 and 2 January 1 - December 31, 2011

• Xcel operated Prairie Island Units 1 and 2 in a manner that preserved public health and safety

• NRC will perform baseline inspections at both Units for 2012.
