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

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 7

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 8

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.

Examples of Baseline Inspections

  • Equipment Alignment ~80 hrs/yr
  • Triennial Fire Protection ~250 hrs every 3 yrs
  • Operator Response ~125 hrs/yr
  • Emergency E Preparedness P d ~80 80 h hrs/yr

  • Rad Release Controls ~110 hrs every 2 yrs
  • Worker Radiation Protection ~95 hrs/yr
  • Corrective Action Program ~250 hrs every 2 yrs

Fukushima Dai-ichi Before Earthquake Reactors 5 & 6 Reactor #1 Reactor #2 Shutdown Operating Operating Reactor # 3 Operating Reactor

  1. 4 Shutdown

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 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 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
