NRC Annual Performance Assessment of Three Mile Island 2007 Reactor Oversight Program 2 Purpose of Today's Meeting

• Discuss AmerGen's Plant Performance for CY 2007 *Provide AmerGen the opportunity to respond to the NRC's Annual Performance Assessment

for Three Mile Island and to identify new or existing programs to continue to improve performance

• Provide stakeholders the opportunity to engage the NRC staff on plant performance issues and our role in ensuring safe plant

operations 3 Agenda*Introduction

• 5933 hours of inspection and related activities

• Two resident inspectors on-site

• 16 regional inspections

• Three major team inspections:

Emergency Preparedness Exercise Physical Security Inspection

Component Design Basis Inspection 16 Three Mile Island PIs / Findings

• All Performance Indicators were Green for CY2007

• 13 Green or Severity Level-IV inspection findings for CY2007 17 NRC Example Inspection Findings

• Severity Level IV -Deficient Control of Overtime during Refueling Outages

• Several Green Findings during Fall Refueling Outage

-Reactor Vessel Water Level anomaly led to Unusual Event-Inadequate Reactor Coolant System Vent Areadue to deficient work controls

-Damaged Control Rod Assembly during Refueling Bridge Operations

-Damaged Fuel Assembly during Refueling Bridge Operations 18 Three Mile Island Performance IndicatorsUnplanned Scrams (G)Unplanned Scrams with Complications (G)Unplanned Power Changes (G)Emergency AC Power System (G)High Pressure Injection System (G)Residual Heat Removal System (G)Heat Removal

• AmerGen operated the plant safely and in a manner that preserved public health and safety and protected the environment.

• TMI was in the Licensee Response column of the NRC's Action Matrix for all four

quarters of 2007.

• NRC plans baseline inspections at TMI for the remainder of CY 2008. Additional

inspections are planned in the areas of

license renewal, and mitigation strategies.
