Watts Bar CY2004 Inspection Activities Approx. 4100 hours0.0475 days <br />1.139 hours <br />0.00678 weeks <br />0.00156 months <br /> of inspection related activities, including:

• Licensed operator requalification inspection

• Radiation protection inspections

• Maintenance inspection

• Triennial Fire protection inspection

• Emergency preparedness inspections

• Reactor operator initial exam

• Unit 2 Systems layup inspection

Watts Bar CY2004 Assessment Results At the time the Assessment Letter was issued on March 2, 2005:

• All performance indicators were Green

• All Unit 1 inspection findings for CY 2004 were classified as very low safety significance (Green)

• Unit 1 performance was considered within the Licensee Response Column of the NRCs Action Matrix

Watts Bar CY2004 Assessment Results We subsequently issued a final significance determination letter and notice of violation on April 11, 2005:

Issue involving silt clogging of a back-up raw cooling water line to the 1A Charging Pump discovered by TVA in November 2004 We identified an inspection finding for inadequate corrective action on previous silt problems that did not prevent this clog Finding was unresolved while the NRC determined safety significance and allowed TVA to supply additional information. Issue was determined to be a White Finding (issue with low to moderate safety significance).

Unit 1 performance now considered within the Regulatory Response Column of the NRCs Action Matrix effective from the 4th Quarter of CY 2004

Watts Bar Annual Assessment Outcome Summary

• TVA operated Watts Bar in a manner that preserved public health and safety

• All cornerstone objectives were met

• NRC had planned baseline inspections at Watts Bar for the remainder of CY 2005 as well as:

- Routine Unit 2 Lay-up inspections

- Steam generator replacement preparation inspections

• We will now also perform a Supplemental Inspection of TVAs root cause evaluation on the White finding (schedule is being planned)

Watts Bar CY2005 Planned Inspection Activities

• Resident inspector daily inspections

• Radiation protection inspections

• Maintenance inspection

• Emergency preparedness inspections

• Problem identification and resolution inspection

• Engineering modification inspection

• Safety system design and performance inspection

• Supplemental Inspection for the White Finding
