/28/03 16 Examination Scope
- Ultrasonic examination (UT) from penetration tube ID
- Enhanced visual exam of J-groove weld surface
- Volumetrically interrogate vessel base metal for wastage
- Eddy current examination (ET) from penetration tube ID
- ET of J-groove weld surface
- Profilometry [tube inside roundness / ovality]
- Metallurgical analyses of removed nozzle remnants

Condition Limited to the Two Identified Nozzles
- Routine inspection identified very low leakage
- Extensive NDE confirmed condition limited to two penetrations
- Axial cracks in tubes
- No wastage
- Substantial safety margin existed
- Monitoring / inspection plan developed

MONITORING / INSPECTION PLAN and RETURN to SERVICE Ed Halpin Plant General Manager
/28/03 23
Monitoring / Inspection Plan Confirms Effective Corrective Action
- Continue bare metal visual inspections under boric acid control program
- Perform UT and EVT of penetrations at next Unit 1 vessel inservice inspection
- Perform periodic UT of vessel base material around repaired penetrations
- Perform volumetric examination of Unit 2 penetrations at next refueling outage with core barrel removal
- Online monitoring plan developed
/28/03 24
Outage Philosophy Three-phase outage approach for long-term focus on nuclear safety and reliability
- Phase One: Discovery
- Phase Two: Repair
- Phase Three: Return to Service
/28/03 25
Return to Service
- Comprehensive communications plan
- PORC reviewed selected activities
- Just-in-time training for plant operators
- Weekly plant walkdowns with key station management to assess readiness
- Increase in staff and manning onshift
- Specific readiness reviews including
- Integrated schedule review
- Refuel project readiness review
- Secondary plant startup review
