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, inspection enforcement, and evaluation of 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

- 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; and

- 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

2009 Dresden Inspection Activities January 1 - December 31, 2009

• Baseline inspections comprised of both Resident Inspector inspections and regional specialist inspections

• Resident baseline inspections (e.g., plant status reviews, equipment lineup walkdowns, maintenance and testing verifications, operator qualification observations, refueling and forced outage activity specific inspections)

• Regional specialist inspections (e.g., license renewal, plant modifications, security, radiation protection, emergency preparedness) 20

Resident Inspector Activities

• Two full time Resident Inspectors assigned to Dresden that have unfettered access at the site

• Monitor plant daily activities and issues (e.g.,

observe control room turnover and plan of the day meetings, ti review i every condition diti report) t)

• Perform independent inspections based on a risk informed approach and knowledge of plant issues

• Respond to the station during abnormal occurrences to observe and assess performance and plant conditions 21

Dresden Overall Assessment Results January 1 - December 31, 2009

• Exelon operated Dresden Units 2 & 3 i a manner that in th t preserved d public bli health and safety

• All NRC cornerstone objectives were met 22

Dresden Assessment Results

• We opened a substantive cross-cutting issue in the Human Performance Area, Work Practice Component, Human Error Prevention Technique Aspect

• Unit 2 is in the Licensee Response Column of the NRC Action Matrix. All Green Findings and Performance Indicators

• Unit 3 is in the Regulatory Response Column of the NRC Action Matrix. 1 White finding and all Green Performance Indicators 23

Safety Significant Findings or PIs

• Unit 3 White Finding - Unplanned Control Rod Withdrawals

• Licensee was isolating all 177 control rods for maintenance.

Non-licensed operators caused three control rods to be partially driven out of the core

• Si il events Similar t have h occurred d outside t id off the th United U it d States St t

• Operating Experience was not adequately utilized by the licensee

• Reactor remained shutdown

• NRC Information Notice 2010-006, Inadvertent Control Rod Withdrawal Event While Shutdown 24

Station Substantive Cross-Cutting Issue in Human Performance

• 22 overall findings

• 14 Green findings in 2009 involved a Human Performance Issue

• 5 out of the 14 findings shared the common aspect of the inadequate usage of human error prevention techniques (i.e.,

self and peer checking, pre-job briefs, proper documentation of activities). H.4(a) (ref. IMC 0310)

• These findings affected multiple NRC cornerstone objectives

• The station has not made sufficient progress to date to address this issue 25

Human Performance Issue Examples

• FIN 2009002-005: Inadvertent actuation of the standby gas ventilation system

• NCV 2009006-001: NRC identified a diesel driven fire pump discharge valve was out of position (i.e.,

shut) h t)

• NCV 2009005-001: Operations personnel incorrectly placed tags

• NCV 2009005-005: Spent fuel assembly moved to the wrong location in the spent fuel pool 26

NRC Inspections Planned for 2010

• Baseline annual ROP inspections

• Baseline Biennial Problem Identification and Resolution team inspection

• Baseline Independent Spent Fuel Storage Installation inspection

• Baseline Triennial Component Design Basis team inspection

• Supplemental IP 95001 inspection to ensure the licensee has taken adequate corrective actions to address the Unit 3 White finding 27
