b. Degradation mechanisms found

Degradationfound included wear at support structures; wear from foreign objects, crack like indication at and above the tube support plates and crack-like indications near the tube ends.

c. Non-destructive examination techniques utilized for each degradation mechanism The bobbin probe was utilized for the detection of wear at support structures, frees pan locations and crack like indication at and above the tube support plates and to size wear at support structures. The array probe was used for detection of indications within the tubesheet, U-bend regions, and the 2 sigma high stress tubes. The array probe was used to size the foreign object wear. The plus point probe was used to size crack like indication at and above the tube support plates
d. Location, orientation (if linear), and measured sizes (if available) of service induced indications.

The complete listing for service induced indications is attached.

e. Number of tubes plugged during the inspection outage for each degradation mechanism Steam Generator 2A:

There were three (3) tubes plugged. Two (2) tubes were plugged due to a wear with a foreign object present. One (1) tube was plugged/or crack like indication at the 3H tube support plate. The tubes plugged were as follows:

g. The results of condition monitoring, including the results of tube pulls and in-situ testing.

The cumulative EFPYfor EOC-20 was 24.24, EOC-21 was 25.67 and EOC-22 was 27.10 and EOC-23 was 28.50.

Condition monitoring was met for all degradation. All structural performance criteria were met for wear with more than adequate margin. Axial outside diameter crack like indications were demonstrated to meet condition monitoring by the length of the flaws being less than the structural length for a limiting through-wall crack. For the two axial outside diameter crack like indications at the same location, the flaws were combined by applying a conservative depth to the intact ligament between the flaws. This combined flaw also met condition monitoring based on a burst pressure calculation. All axial outside diameter crack like indications met condition monitoring for leakage because the voltages were less than the threshold voltage for leakage Foreign Object Search and Retrieval (FOSAR) was performed in areas ofknown foreign object accumulation or where indicated by eddy current examination. FOSAR was performed at the top of tube sheet and the waterbox/preheater section. All historical foreign objects that were not removed have a technical evaluation demonstrating that tube integrity will be met through the next scheduled inspection of this region at EOC-25.

An upper bundle visual inspection was performed in the steam generator 2A, no degradation was detected.

No degradation was detected in the plug visual.

Bowl cladding inspections at EOC-21 did identify an area of missing stainless-steel cladding in the Catawba Unit 2 SG D hot leg channel head. The area ofmissing stainless-steel cladding was inspected at EOC-23 no changes were noted.

There was no degradation detected in any of the other bowl cladding inspections.

No in-situ tests or tube pulls were performed.

h. For Unit 2, the primary to secondary LEAKAGE rate observed in each SG (if it is not practical to assign leakage to an individual SG, the entire primary to secondary LEAKAGE should be conservatively assumed to be from one SG) during the cycle preceding the inspection which is the subject of the report.

There was no primary to secondary leakage above detection limits during the preceding cycle 23 operation.

i. For Unit 2, the calculated leakage rate from the portion of the tubes below 14.01 inches from the top of the tubesheet for the most limiting accident in the most limiting SG. In addition, if the calculated accident leakage rate from the most limiting accident is less than 3.27 times the maximum primary to secondary LEAKAGE rate, the report shall describe how it was determined.

There was no calculated leakage from the portion of the tubes more than 14.01 inches from the top of the tubesheet, for the most limiting accident in the most limiting SG.

j. For Unit 2, the results of monitoring for tube axial displacement (slippage). If slippage is discovered, the implications of the discovery and corrective action shall be provided.

No indications of slippage were detected.
