Quad Cities Nuclear Power Station Annual Assessment 1

Annual Assessment Meeting Reactor Oversight Process - 2011 Nuclear Regulatory Commission - Region III Cordova, IL June 12, 2012

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.

Japan Earthquake and Tsunami March 11, 2011

Sequence of Events Three operating units shutdown at time of earthquake Offsite power lost; emergency diesels supply power 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> later Tsunami strikes site and wipes-out emergency power.

Extended station blackout -loss of all AC power Extended station blackout loss of all AC power DC batteries deplete and subsequent loss of reactor cooling Late injection of seawater using fire trucks Significant core damage at units 1, 2, and 3 Hydrogen generated from metal water reaction in cores Hydrogen explosions in Units 1, 3, and 4 reactor buildings Spent Fuel Pool status indications lost -distracted attention from damaged reactors Tsunami exceeded the design assumption that led to extensive plant damage and extended station blackout

Reactors 3 & 4 Post-Event

NRC Actions Post Fukushima

  • Immediate response measures including NRC assist team to Japan
  • Prompt (April & May) inspections of
  • Prompt (April & May) inspections of capability of US nuclear plants
  • Near Term Task Force

Conclusions:

- US nuclear plants are safe

- Use Fukushima Lessons Learned to enhance safety at US nuclear plants

NRC Orders and Information Requests

  • Strategies and equipment for beyond-design-basis phenomena
  • Reevaluation of seismic & flood hazards
  • Design basis check for seismic & flood
  • Prolonged blackout communications
  • Staffing for multi-unit and prolonged blackout events
