NRC CY2003 Annual Assessment Meeting Oconee Nuclear Station Seneca, South Carolina April 13, 2004
Purpose of Todays Meeting l A public forum for discussion of the licensees performance l NRC will address the licensee performance issues identified in the annual assessment letter l Licensee 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 l Introduction l Review of Reactor Oversight Process l National Summary of Plant Performance l Discussion of Plant Performance Results l Licensee Response and Remarks l NRC Closing Remarks l Break l NRC available to address public questions
Region II Organization Luis Reyes Regional Administrator Loren Plisco Deputy Regional Administrator Victor McCree Charles Casto Director Division of Reactor Projects Director Division of Reactor Safety Len Wert Harold Christensen Deputy Director Deputy Director Robert Haag Branch Chief Oconee Resident Inspectors Project Engineers Mel Shannon Robert Carroll George Hutto Michael Pribish Eric Riggs
NRC Performance Goals l Maintain safety and protect the environment l Enhance public confidence l Improve effectiveness, efficiency, and realism of processes and decision making l Reduce unnecessary regulatory burden
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 l Equipment Alignment ~92 hrs/yr l Triennial Fire Protection ~200 hrs every 3 yrs l Operator Response ~125 hrs/yr l Emergency Preparedness ~80 hrs/yr l Rad Release Controls ~100 hrs every 2 yrs l Worker Radiation Protection ~100 hrs/yr l Corrective Action Program ~200 hrs every 2 yrs l Corrective Action Case Reviews ~60 hrs/yr
Oconee Nuclear Station 5100 Hours of Inspection Related Activities (Jan 1 - Dec 31, 2003) l Supplemental Inspection (95001 - HPI cable) l Special Inspection (main steam ADVs) l Engineering Inspections l Emergency Preparedness Inspection l Initial Operator Exam and Requalification Inspection l Reactor Vessel Head/Steam Generator Replacement and Lower Head Inspections l Radiation Protection and Security Inspections l Problem Identification and Resolution Inspections l ISFSI Inspection
Significance Threshold Performance Indicators Green: Only Baseline Inspection White: May increase NRC oversight Yellow: Requires more NRC oversight Red: Requires more NRC oversight Inspection Findings Green: Very Low safety issue White: Low to moderate safety issue Yellow: Substantial safety issue Red: High safety issue
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 2003 Licensee Response 75 Regulatory Response 22 Degraded Cornerstone 2 Multiple/Repetitive Degraded Cornerstone 3 Unacceptable 0 Total 102*
- Davis-Besse is under a special restart inspection process (IMC 0350)
Oconee Nuclear Station Assessment Results For CY 2003 l All Performance Indicators Were Green Requiring No Additional NRC Inspection l One White Inspection Finding
