STEAM GENERATOR INSERVICE INSPECTION -

CYCLE 5 TWELVE MONTH REPORT (TAC No. MC1048)

In accordance with the requirements in WBN Technical Specification 5.9.9, "SG Tube Inspection Report," the enclosure provides the Steam Generator Inservice Inspection Report for Cycle 5. This report is required to be submitted within twelve months following the refueling outage and provides the complete results of the tube inspections.

Other reports required by Technical Specification 5.9.9 were previously submitted on October 13, 2003, F* Alternate Repair Criteria Report, and October 13, 2003, 15-day Report.

TVA also submitted a 90-day Report concerning the use of an alternate repair criterion for outside diameter stress corrosion cracking (ODSCC) on January 15, 2004, as committed in TVA's letter dated April 10, 2000, concerning the license amendment request for use of this alternate repair criterion.

The metallurgical examination results of the pulled steam generator tube from the Cycle 5 Refueling Outage were submitted May 20, 2004.

In addition, TVA responded to a request for additional information concerning the Cycle 5 steam generator inspections on July 19, 2004.

During preparation of the subject report, TVA identified five tubes which were repaired during the refueling outage with Alloy 800 sleeves, and also had a single indication of greater than forty percent of the nominal wall below the level of the sleeves in the tubesheet region.

TVA personnel interpreted the Watts Bar Unit 1 Technical Specification Section 5.7.1.12.g(f),

Pwedon mecycd p3

U.S. Nuclear Regulatory Commission Page 2 SEP 2 4 2004 "Plugging Limit," as allowing the tubes to remain in service by using the alternate repair criteria, F-star (F*).

The tubes were also sleeved during this outage thus, the location of the bottom of the roll transition was known.

Each of the indications was well below the bottom of the tube sleeve.

TVA has documented this condition on a Problem Evaluation Report, 67155. A functional evaluation has been performed and determined that the sleeved tubes are fully capable of performing their specified safety function, considering the distance of the indications within the tubesheet region and below the bottom of the sleeve.

No operability concerns exist.

The enclosed report completes the reporting requirements for the steam generator inspections during Unit 1 Cycle 5 outage.

There are no regulatory commitments identified in this submittal.

If you have any questions about these responses, please contact me at (423) 365-1824.

Watts Bar Nuclear Plant Unit I Cycle 5 RFO Inspection October 2003 Table 2.1 SG I Indications The following indications are outside diameter stress corrosion cracking at tube support plates.

The eddy current call 'DSI" is a bobbin probe call with the associated voltage listed. The call

'SAI" is a plus point probe call with the associated voltage listed. If the bobbin voltage is less than 1 volt, the indication may remain in service via the ODSCC Generic Letter 95-05 Alternate Repair Criteria (ARC). Details of these indications were reported in the required 90-Day Report.

If the indication is greater than I volt but not confirmed with plus point probe, the indication may remain in service via the ARC.

The eddy current call 'DSI" is a bobbin probe call with the associated voltage listed. The call

'SAI" is a plus point probe call with the associated voltage listed. If the bobbin voltage is less than I volt, the Indication may remain in service via the ODSCC Generic Letter 95-05 Alternate Repair Criteria (ARC). Details of these indications were reported in the required 90-Day Report.

If the indication is greater than 1 volt but not confirmed with plus point probe, the indication may remain in service via the ARC.

Watts Bar Nuclear Plant Unit 1 Cycle 5 RFO Inspection October 2003 Table 2.3 SG 3 Indications The following indications are outside diameter stress corrosion cracking at tube support plates.

The eddy current call 'DSI" is a bobbin probe call with the associated voltage listed. The call "SAI' is a plus point probe call with the associated voltage listed. If the bobbin voltage is less than 1 volt, the indication may remain in service via the ODSCC Generic Letter 95-05 Alternate Repair Criteria (ARC). Details of these indications were reported in the required 90-Day Report.

If the indication is greater than 1 volt but not confirmed with plus point probe, the indication may remain in service via the ARC.

The following indications were plugged due to loose parts wear. The "LPI" call is a bobbin coil probe call with associated voltage. This call indicates a need to further evaluate with plus point. The 'SVI" is a plus point probe call with associated voltage indicating the indication is volumetric wear. The TBP is a lead analyst call to ensure the surrounding tubes are plugged preventively:
