Program Objective review of licensee performance Action Matrix identifies agency response commensurate with safety significance Increasing safety significance results in:

- Increased levels of inspection

- Involvement of higher levels of NRC and Licensee Management

- Increased regulatory action 14

SAFETY SIGNIFICANCE GREEN - very low WHITE - low to moderate YELLOW - substantial RED - high 15

Reactor Oversight Process Licensee safety performance is monitored by:

• performance indicators

• evaluating inspection findings Safety performance letter written every six months Public meetings on annual basis www.NRC.gov/reading-rm/adams.html 21

Performance Summary 22

Inspection Results

• NRC and Licensee identified inspection findings were of very low safety significance

• Inspection results within the Licensee Response Band

• No special or supplemental inspections necessary 23

Results All performance indicators within the Licensee Response Band 24

Assessment Conclusion Licensee effectively managed:

- Reactor safety

- Radiation safety

- Plant security Arkansas Nuclear One operated in a manner that protected the health and safety of the public 25

Additional Focus Areas

• NRC Responds As-Needed

• Mandate Licensee Actions

• Implement Emergency Response 28

Nuclear Industry Issues Potential Reactor Vessel Head Degradation Security at Nuclear Power Plants 29

Reactor Vessel Head Degradation Wastage found on Davis-Besse reactor vessel head Inspections required by Bulletins Lessons Learned Order Issued 30

Reactor Vessel Head Degradation NRC specialists monitored ANO reactor vessel head inspection during Unit 1 and Unit 2 Outages Reactor vessel heads did not have wastage 31

Security at Nuclear Power Plants

• NRC created Office of Nuclear Security and Incident Response

- Provides more efficient counterpart to Office of Homeland Security

• Top-to-bottom review of Security Program Initiated 32

Security at Nuclear Power Plants Issuance of Orders/Interim Compensatory Measures (ICM)

Verification of licensee actions regarding ICMs 33

Security at Nuclear Power Plants Pending Orders on fatigue/guard training Initiation of pilot Force-on-Force Exercise NRC working with FAA has prohibited planes from circling or loitering above nuclear power plants Has expanded involvement with other federal agencies 34

Threat Advisory and Protective Measures System communicates threats affecting NRC licensees corresponds to color-coded Homeland Security Presidential Directive Identifies specific actions to be taken by NRC licensees for each threat level 35
