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 i d by b the h President P id and d confirmed fi d byb theh Senate S for f

staggered five-year terms.

Chairman Commissioner Commissioner Commissioner Commissioner Gregory B. Kristine L. George William D. William C.

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.

6

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.

7

The NRC Regulates

  • Nuclear reactors

- commercial power reactors, research and test reactors, new reactor designs

  • Nuclear materials

- nuclear reactor fuel fuel, radioactive materials for medical 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 8

What We Dont Do

  • We do not regulate nuclear weapons, military reactors, or space vehicle reactors
  • We do not own or operate nuclear power plants
  • We do not regulate some radioactive materials, such as X-rays and naturally occurring radon 9

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 10

Assurance of Plant Safety

  • Require defense-in-depth
  • Require long-term maintenance of equipment
  • Require continual training of operators
  • Verify compliance with regulations 11

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, such as the proposed Yucca Mountain site.

12

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, and

- Intrusion detection systems and alarm stations.

13

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.

14

Reactor Oversight Process 3 Strategic g 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 performance deficiency)

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 15

Examples of Baseline Inspections Some of the Routine Inspections Conducted at Every Plant

  • Equipment Alignment ~80 hrs/yr
  • Operator Response ~125 hrs/yr
  • Worker Radiation Protection ~95 hrs/yr
  • Corrective Action Case Reviews ~60 hrs/yr
  • Corrective Action Program ~250 hrs every 2 yrs
  • Rad Release Controls ~110 hrs every 2 yrs
  • Triennial Fire Protection ~250 hrs every 3 yrs 17

Braidwood Assessment Results January 1 - December 31, 2009

  • Human Performance Substantive Cross-Cutting Issue regarding conservative assumptions in decision-making remains open

- IInitially iti ll opened d in i July J l 2009

- Licensee has implemented comprehensive improvement actions

- NRC will continue to evaluate the effectiveness of the licensees actions 23

Safety Significant Findings or PIs January 1 - December 31, 2009

  • One White Finding identified for Unit 1

- Emergency core cooling system valve failed a periodic surveillance test

- Purpose of the valve is to provide a secondary source of cooling water to the emergency core cooling system after the useable volume of primary water runs out

- Cause of the valve failure was corrosion of the valve torque switch due to standing water in the valve actuator housing

- Source of the water was rainwater leaking through a roof hatch and dripping into an open-ended conduit containing a cable associated with the valve 24

Braidwood Inspection Activities January 1 - December 31, 2009 Examples of inspections conducted in addition to daily resident inspector activities

  • Dry Cask Storage Infrastructure Construction (Ongoing)
  • Triennial Fire Protection Inspection (January 26 to March 6)
  • Unit 1 Refueling Outage (March 30 to April 19
  • Initial Operator License Examination (October 5 to 29)
  • Unit 2 Refueling Outage (October 12 to 29) 25

Braidwood Annual Assessment Summary January 1 - December 31, 2009

  • Exelon operated Braidwood Units 1 & 2 in a manner that preserved public health and safety.
  • All cornerstone objectives were met
  • One White Finding was identified for Unit 1
  • Human Performance Substantive Cross-Cutting Issue remains open
  • NRC will increase oversight of Braidwood Unit 1 in 2010 through a supplemental inspection to evaluate actions taken in response to the White Finding 26
