• NRC requires plants to be designed to withstand external events

• NRC requires a defense-in-depth approach to NRC requires a defense in depth approach to safety

• NRC performs independent safety inspections

• NRC assesses new safety information and requires improvements 10

Designed for Site Specific Natural Events

• Earthquakes

• Tsunamis

• Floods

• Tornadoes 11

The NRC Requires Defense-In-Depth

• Redundant and diverse safety systems

• Multiple physical barriers to

• Multiple physical barriers to contain radioactive material

• Testing and inspection of systems important to safety

• Emergency planning 12

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 14

• Rulemaking (Station Blackout)

• Post TMI Actions

• Post 9/11 Orders

• Generic Safety Issues

NRC Response to Events in Japan
