NRC Performance Goals
! Safety:Ensure protection of the public health and safety and the environment
! Security: Enhance the secure use and management of radioactive materials
! Openness: Ensure openness in our regulatory process
! Effectiveness: Ensure that NRC actions are effective, efficient, realistic, and timely
! Management: Ensure excellence in agency management to carry out the NRCs strategic objectives
Reactor Oversight Process Strategic Performance Areas Safety Cornerstones Performance Indicator Baseline Inspection Results Results Significance Significance Threshold Threshold Action Matrix Regulatory Response
Examples of Baseline Inspections
! Equipment Alignment ~92 hrs/yr
! Triennial Fire Protection ~200 hrs every 3 yrs
! Operator Response ~125 hrs/yr
! Emergency Preparedness ~80 hrs/yr
! Rad Release Controls ~100 hrs every 2 yrs
! Worker Radiation Protection ~100 hrs/yr
! Corrective Action Program ~200 hrs every 2 yrs
! Corrective Action Case Reviews ~60 hrs/yr
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
Purpose of Todays Meeting
! A public forum for discussion of the licensees performance
! NRC will address the licensee performance issues identified in the annual assessment letter
! Licensee will respond to the information in the letter and inform the NRC of new or existing programs to maintain or improve their performance
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 Units 102
- Davis-Besse is in IMC 0350 process

Dresden Assessment Results (Jan 1 - Dec 31, 2004)
! Licensee Response Column of Action Matrix
! Special Inspection on Unit 3 Loss of Offsite Power in May 2004 -resulted in three self-revealed Green Findings
! Supplemental Inspection (95001) for Scrams in October 2004 - no significant findings identified
Safety Significant Findings or PIs
! No greater than Green Findings
! No greater than Green Performance Indicators at the end of the year
< White PI on Unit 3 Safety System Unavailability from 2001 HPCI Waterhammer turned Green in 3Q2004
< White PI on Unit 2 Unplanned Scrams in 2Q2004, completed Supplemental Inspection, PI turned Green in 3Q2004
! Continued Substantive Cross-Cutting Issue in Human Performance
Dresden Inspection Activities (Jan 1 - Dec 31, 2004)
! 27 Green Findings
! Problem Identification & Resolution Inspection -February 2004
! Special Inspection on Unit 3 Loss of Offsite Power -May 2004
! IP 95001 Supplemental Inspection for scrams PI -October 2004
< January 24 - Unit 3 scrammed due to the failure of the master trip solenoid valve
< January 30 - Unit 3 experienced a turbine trip followed by a reactor scram
< April 24 - Unit 2 scrammed due to a Group 1 isolation
< April 28 - Unit 2 manually scrammed due to a trip of the 2 A reactor recirculation pump
< May 5 - Unit 3 scrammed due to a loss of offsite power
Dresden Inspection Activities (continued)
(Jan 1 - Dec 31, 2004)
! License Renewal for Units 2 & 3 - October 2004
! Unit 3 Refueling Outage - October 2004
< Cracking identified on steam dryer and main generator rotor
< Repair of steam dryer and main generator rotor shaft
! Unit 2 main generator and steam dryer inspection -November 2004
< Cracking identified on steam dryer and main generator rotor
< Repair of steam dryer and main generator rotor
Dresden Annual Assessment Summary January 1- December 31, 2004
! Exelon operated Dresden Units 2 & 3 in a manner that preserved public health and safety
! All cornerstone objectives were met with only one White PI identified (Unplanned Scrams per 7000 Critical Hours) which subsequently turned Green
! NRC plans baseline inspections at Dresden for the remainder of the assessment period and IP 71004, Extended Power Uprate (EPU), if Exelon decides to replace the steam dryers
