Beaver Valley Assessment Meeting U.S. Nuclear Plant Safety in Light of Japan Events 9

U.S. Nuclear Plants Remain Safe

  • NRC requires plants to be designed to withstand external events
  • NRC requires a defense-in-depth approach to safety
  • NRC performs independent safety inspections
  • NRC assesses new safety information and requires improvements 10 5

Designed for Site Specific Natural Events

  • Tsunamis
  • Hurricanes
  • Floods
  • Tornadoes 11 The NRC Requires Defense-In-Depth
  • Redundant and diverse safety systems
  • Multiple physical barriers to contain radioactive material
  • Testing and inspection of systems important to safety
  • Emergency planning 12 6

NRC Independent Safety Inspections Reactor Oversight Program

  • NRC inspectors have unfettered access to all plant activities related to nuclear safety and security
  • At least two full-time NRC resident inspectors at each nuclear plant
  • NRC specialists conduct additional inspections at each nuclear plant 13 NRC Requires Safety Improvements NRC assesses new safety information, develops lessons learned, and requires safety enhancements:
  • NRC operating experience program
  • Rulemaking (Station Blackout)
  • Post TMI Actions
  • Post 9/11 Orders
  • Generic Safety Issues 14 7

NRC Response to Events in Japan

  • NRC conducting a methodical and systematic review
  • Near-term actions (<90 days)
