Catawba I EOC21 Steam Generator Tube Inspection Report Pursuant to ASME Section XI and Catawba technical specification 5.6.8 the following information is provided:

a. The scope of inspection performed on each SG The unit 1 steam generatorshad an accumulatedservice life of 14.6 EFPY at the end of cycle 20 and 16 EFPY by the end of cycle 21.

Baseline inspection scope shall includefull length data acquisitionand bobbin coil analysisfor allfour (4) steam generatorsas follows.

1) All tubes with previous indications.

2) All tubes surroundingplugged tubes.

3) Peripherytubes two rows deep of the hot leg and cold leg (outer perimeterand open lane) with bobbin probe.

4) Arrayprobe acquisitionand analysisfive tubepitches deep on periphery- hot leg, cold leg, and along open lanefrom top of tubesheet up to the first lattice grid.

5) 50% random sample of remaining in-service tubes.

Note: There were 3,742 tubes inspected with bobbin in the A SG, 3,739 in the B SG, 3, 738 in the C SG, and 3,783 in the D SG.

Special interest inspection scope shall include data acquisitionand arraydata analysis as follows:

1) Locations where bobbin coil indicationsare observed that requirefurther characterization.

2) New dent and new % through wall indications.

3) Bounding inspections aroundall PLP indicationsconfirmed with array.

4) Ten pairs ofperiphery tubes in SG ID, monitoringfor evidence of tubes touching.

No touching is evident.

Plug inspectionscope shall be asfollows:

1) Visual inspection of all plugs. There was no degradationobserved.

2) Bowl cladding inspection (NSAL 12-1). There was no degradationobserved.

b. Active degradation mechanisms found Active degradationfound in allfour (4) steam generatorsinclude wear at support structures and wearfrom loose objects.

Page 5 of 15

c. Non-destructive examination techniques utilized for each degradation mechanism Bobbin was used to detect wear at support structures.Bobbin and array were used to detect wearfrom loose objects.

d. Location, orientation (if linear), and measured sizes (if available) of serviced induced indications The complete listingfor service induced indicationsis attached.

e. Number of tubes plugged during the inspection outage for each active degradation mechanism No tubes werefound to requireplugging.

f. The total number and percentage of tubes plugged to date I SG A SG B I SG C SG D Total Priorto EOC21 8 0 24 17 49 EOC21 0 0 0 0 0 Total 8 0 24 17 49

% Plugged 0.12 0.00 0.36 0.26 0.18 Each SG contains 6,633 tubes

g. The results of the condition monitoring, including the results of tube pulls and in-situ pressure testing Condition monitoringand operationalassessment evaluationsfor the Catawba Unit 1 steam generatorswere performed based on the inspection resultsfrom JEOC21. These evaluations were performed accordingto NEI 97-06 using proceduresfrom the EPRI Steam GeneratorIntegrity Assessment Guidelines and the EPRI Steam Generator DegradationSpecific Management Flaw Handbook.

The observed tubing degradationat JEOC21 consistedof wear at tube support locations and two instances ofpreviously detectedforeign object wear. The maximum observed NDE degradationdepth for wear at support structureswas 31% TW. The projected worst case support structurewearfrom the JEOCJ9 CMOA was 48% TW. As predicted by the previous CMOA, there was no growth offoreign object wear locationsfrom JEOC19 to JEOC21. Therefore, the 1EOC19 CMOA calculationwas appropriateand conservative.

No tube plugging was performed at CNS JEOC21. The present state of degradationof the Catawba Unit I steam generatortubing is very mild and does not challenge structuraland leakage integrity requirements.Acceptable structuraland accident leakage integrity is projectedfor the next 3.0 EFPY of operation.
