Sequoyah Nuclear Plant Unit 2 Cycle 12 RFO Inspection November 2003 Table 2.1 SG 1 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 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 I volt but not confirmed with plus point probe, the indication may remain in service via the ARC.

Sequoyah Nuclear Plant Unit 2 Cycle 12 RFO Inspection November 2003 Table 2.2 SG 2 Indications The following indications are outside diameter stress corrosion cracking at tube support plates.

The eddy current call ODSI" 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.

Sequoyah Nuclear Plant Unit 2 Cycle 12 RFO Inspection November 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 "SAl' 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.

Sequoyah Nuclear Plant Unit 2 Cycle 12 RFO Inspection November 2003 Table 2.4 SG 4 Indications The following indications are outside diameter stress corrosion cracking at tube support plates.

The eddy current call 'DSI1 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.
