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 i

Our Mission To license and regulate the nations civilian use of byproduct, source, and special nuclear materials to 6
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 7
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 8
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
What We Dont Do
- We do not regulate nuclear weapons, military reactors, or space vehicle reactors 9
- We do not own or operate nuclear power plants
- We do not 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
10 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 11
- 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 12 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, 13 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.
14 Security Ensure adequate protection in the secure use and management of radioactive materials.
Reactor Oversight Process
3 Strategic Performance Areas are divided into 7 g
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

22 One White Finding identified associated with a Unit 1 emergency core cooling valve failing to stroke open during periodic testing 16 Green findings and 1 Severity Level IV violation All performance indicators were Green Human Performance Substantive Cross-Cutting Issue remains open
Braidwood Assessment Results January 1 - December 31, 2009 Human Performance Substantive Cross-Cutting Issue regarding conservative assumptions in decision-making remains open I iti ll d i J l 2009 23
- Initially opened in July 2009
- Licensee has implemented comprehensive improvement actions
- NRC will continue to evaluate the effectiveness of the licensees actions
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 24
- 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
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) 25 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)
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 26 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
