Davis-Besse Nuclear Power Station Annual Assessment Meeting 1
2009 Reactor Oversight Program Nuclear Regulatory Commission - Region III Oak Harbor, Ohio July 29, 2010
Purpose of Todays Meeting
- A public forum for discussion of Davis-Besses performance in 2009
- NRC will address the performance issues identified in the annual assessment letter 2
- The recent CRDM nozzle cracking issues on the reactor head were discovered after the 2009 assessment period
- A Special Inspection exit meeting will be scheduled soon to discuss these issues in depth
- Plant management will be given an opportunity to respond and inform the NRC of new or existing programs to maintain or improve 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 i

appointed by the President and confirmed by the Senate for staggered five-year terms.

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 radiation sources, 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

Safety Significant Findings or PIs January 1 - December 31, 2009
- One White Finding identified during the 4th Quarter of 2009
- On June 25, 2009, an explosion in the switchyard 23 p
y was observed by plant personnel, caused some plant equipment to lose power, and generated main control room alarms.
- Davis-Besse did not correctly assess that these conditions met the criteria in plant procedures for declaring an Alert

Davis-Besse Annual Assessment Summary January 1 - December 31, 2009 FirstEnergy Nuclear Operating Company operated Davis-Besse Unit 1 in a manner that preserved public health and safety.
All cornerstone objectives were met.
25 One White Finding was identified for Unit 1 in the 4th Quarter of 2009.
No Substantive Cross-Cutting Issues were identified.
NRC will increase oversight of Davis-Besse Unit 1 in 2010 through a supplemental inspection to evaluate actions taken in response to the White Finding.
