Our Mission

nuclear materials to ensure adequate protection of public health and safety, promote the common defense and security, and protect the environment.

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 4

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.

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 5
  • 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

What We Dont Do

  • Regulate nuclear weapons, military reactors, or space vehicle reactors 6
  • Own or operate nuclear power plants
  • Regulate some radioactive materials, such as X-rays and naturally occurring radon

How We Regulate

  • Establish rules and regulations
  • Issue licenses
  • Provide oversight through inspection, f

t d

l ti f

7 enforcement, and evaluation of operational experience

  • Conduct research to provide support for regulatory decisions
  • Respond to events and emergencies

Assurance of Plant Safety

  • Require defense-in-depth
  • Require long-term maintenance of equipment 8
  • Require continual training of operators
  • Verify compliance with regulations

What We Do - Nuclear Waste

  • The NRC regulates:

- Storage of spent reactor fuel in fuel pools or dry storage casks and 9

casks, and

- Any national spent fuel storage site, such as the proposed Yucca Mountain site.

What We Do - Nuclear Security

  • NRC Requires:

- Well-armed and well-trained security forces,

- Surveillance and perimeter patrols, 10 perimeter patrols,

- State-of-the-art site access equipment and

controls,

- Physical barriers and detection zones, and

- Intrusion detection systems and alarm stations.

NRC Performance Goals

  • Safety: Ensure adequate protection of public health and safety and the environment.

11

  • Security: Ensure adequate protection in the secure use and management of radioactive materials.

Finding data current as of 3/3/2011

Dresden Assessment Results January 1 - December 31, 2010

  • Dresden is in the Licensee Column of 18 the Action Matrix
  • There were eighteen (18) Severity Level IV or Green findings or violations identified

Dresden Assessment Results January 1 - December 31, 2010

  • Dresden began 2010 in the Regulatory Response Column of the Action Matrix for a White finding identified in 2009 19 White finding identified in 2009
  • After a Supplemental Inspection, the White finding was closed during the 2010 Mid-Cycle Assessment and Dresden transitioned back to the Licensee Response Column

Dresden Assessment Results January 1 - December 31, 2010

  • A Substantive Cross-Cutting Issue (SCCI) in Human Performance was opened in the 2009 End-of-Cycle Assessment due to 20 several findings associated with Human Error Prevention Techniques
  • Due to Exelons significant corrective actions in this area, as well as a significant decrease in the number of findings related to this area, this SCCI was closed in the 2010 Mid-Cycle Assessment

NRC Inspection Findings Dresden

  • Green - Exelon failed to monitor U3 drywell temperature to ensure that equipment operated within its environmental qualification limit 21 q
  • Green - Exelon failed to perform a tube leak test or calculations on the 3A LPCI/CCSW heat exchanger as required by procedures
  • Green - Exelon failed to properly classify LPCI pump mechanical seals as safety-related equipment
