R. E. Ginna Nuclear Power Plant Assessment Meeting 10 U.S. Nuclear Plant Safety in Light of Japan Events
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 11
Designed for Site Specific Natural Events
- Tsunamis
- Hurricanes
- Floods
- Tornadoes 12
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 13
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 14
NRC Requires Safety Improvements NRC assesses new safety information, develops lessons learned, and requires safety enhancements:
15
- NRC operating experience program
- Rulemaking (Station Blackout)
- Post TMI Actions
- Post 9/11 Orders
- Generic Safety Issues
NRC Response to Events in Japan
- NRC conducting a methodical and systematic review 16
- Near-term actions (<90 days)
- conducting additional inspections
- identifying near-term operational issues
- Longer-term actions
Directors Comments 17 Darrell Roberts, Director Division of Reactor Projects USNRC, Region I
