NRC CY2004 Annual Assessment Meeting Oconee Nuclear Station Seneca, South Carolina April 27, 2005

Purpose of Todays Meeting z A public forum for discussion of Oconee Nuclear Stations performance z NRC will address the licensee performance issues identified in the annual assessment letter z Oconee Management will be given the opportunity to respond to the information in the letter and inform the NRC of new or existing programs to maintain or improve their performance

Agenda z Introduction z Review of Reactor Oversight Process z National Summary of Plant Performance z Discussion of Plant Performance Results z Oconee Management Response and Remarks z NRC Closing Remarks z Break z NRC available to address public questions

Region II Organization William Travers Regional Administrator Loren Plisco Deputy Regional Administrator Victor McCree Charles Casto Director Division of Reactor Projects Director Division of Reactor Safety Anne Boland Harold Christensen Acting Deputy Director Deputy Director Michael Ernstes Branch Chief Regional Specialists Oconee Resident Inspectors Project Engineers Mel Shannon Robert Carroll George Hutto Brian Anderson Eric Riggs

NRC Performance Goals PRIMARY GOALS Ensure protection of the public health and safety and the environment Enhance the secure use and management of radioactive materials OTHER GOALS

• Ensure openness in NRC regulatory process

• Ensure that NRC actions are effective, efficient, realistic, and timely

• Ensure excellence in NRC management to carry out the NRCs strategic objective

Reactor Oversight Process Strategic Performance Areas Safety Cornerstones Baseline Inspection Performance Indicator Results Results Significance Significance Threshold Threshold Action Matrix Regulatory Response

Examples of Baseline Inspections z Equipment Alignment ~92 hrs/yr z Triennial Fire Protection ~200 hrs every 3 yrs z Operator Response ~125 hrs/yr z Emergency Preparedness ~80 hrs/yr z Rad Release Controls ~100 hrs every 2 yrs z Worker Radiation Protection ~100 hrs/yr z Corrective Action Program ~200 hrs every 2 yrs z Corrective Action Case Reviews ~60 hrs/yr

Oconee Nuclear Station 5400 Hours of Inspection Related Activities (Jan 1 - Dec 31, 2004) z Supplemental Inspection (95002 - HPI cable and SSF PZR heaters) z Reactor Containment Sump Blockage Inspection z Engineering and Maintenance Inspections (e.g., SSDPC, ISI, etc..)

z Emergency Preparedness Inspection z Operator Licensing Exam z Reactor Vessel Head/Steam Generator Replacement and Lower Head Inspections z Radiation Protection Inspections z Spent Fuel Material Control and Accountability Inspection z ISFSI Inspections z Offsite Power System Operational Readiness Inspection

Performance Thresholds Safety Significance Green: Very low safety issue White: Low-to-moderate safety issue Yellow: Substantial safety issue Red: High safety issue NRC Inspection Efforts Green: Only Baseline Inspections White: May increase NRC oversight Yellow: Increased NRC oversight Red: Increased NRC oversight and other NRC actions

Action Matrix Concept Licensee Regulatory Degraded Multiple/Rep. Unacceptable Response Response Cornerstone Degraded Performance Cornerstone Increasing Safety Significance Increasing NRC Inspection Efforts Increasing NRC/Licensee Management Involvement Increasing Regulatory Actions

National Summary of Plant Performance Status at End of CY 2004 Licensee Response 78 Regulatory Response 21 Degraded Cornerstone 0 Multiple/Repetitive Degraded Cornerstone 3 Unacceptable 0 Total 102*

• Davis-Besse is under a special inspection process (IMC 0350)

Oconee Nuclear Station Assessment Results (Jan 1 - Dec 31, 2004) z All Performance Indicators Were Green Requiring No Additional NRC Inspection z One White Inspection Finding 3/4Failure to maintain the licensing basis commitment for staffing the SSF in the event of a confirmed plant fire:

Affected All Three Units 3rd and 4th Qtr 2004 z One White Inspection Finding Carried Over From CY2003 3/4Inadequate SSF Pressurizer Heater Capacity:

Affected All Three Units 1st through 3rd Qtr 2004

Oconee Nuclear Station Assessment Results (Jan 1 - Dec 31, 2004) z All Three Units - Regulatory Response Column of Action Matrix for 1st and 2nd Qtr 2004:

3/4 Due to White SSF Pressurizer Heater Finding z All Three Units - Degraded Cornerstone Column of Action Matrix for 3rd Qtr 2004:

3/4 Due to Overlap of Two Mitigating Systems Findings (i.e., SSF Pressurizer Heater and SSF Manning) in the Same Quarter z All Three Units - Regulatory Response Column of Action Matrix for 4th Qtr 2004 3/4 Due to White SSF Manning Finding

Oconee Nuclear Station Assessment Results (Jan 1 - Dec 31, 2004) z Severity Level III Violation (with $60,000 civil penalty) z Failure to Obtain NRC Approval Prior to Making a Change to the Facility Which Involved Unreviewed Safety Questions z Corrective Actions to be Followed Up On During a Future Baseline Inspection

Application of Action Matrix (Jan 1 - Dec 31, 2004)
