The following describes the scope of the Inspection performed at Catawba Unit 2 for EOC-14 in March 2006:
A bobbin coil eddy current inspection was performed at Catawba Unit 2 EOC-14 in March 2006. The tubes selected for the bobbin inspection included tubes with previous indications, tubes on the periphery of the bundle two rows deep, tubes surrounding plugged tubes and a minimum sample of 20 %of remaining tubes including all tubes not inspected with bobbin since EOC -10. During the outage additional tubes were added to the inspection plan to bound possible loose parts identified by eddy current and visual inspection. The total tubes inspected by bobbin per steam generator can be found in Table 1.

The tubesheet region was inspected with the array probe. The tubes selected for the inspection included a 20 %
random sample, all periphery tubes, all of the historical overexpansions and 20 %of the newly identified overexpansions. Relative to the latter, there was a new criterion developed to more consistently identify overexpansions. The tubesheet inspection was performed from two inches above the top of tubesheet through the tube end. The total number of tubes inspected by the array probe in the tubesheet region per steam generator can be found in Table 1.

The total number of tubes inspected by the array probe in the tubesheet region per steam generator can be found in Table 1.
Small radius u bends were also inspected by the array. The tubes selected include a 20 % sample of rows one, two and ten. The tubes selected by the bobbin plan in row 3 and 4 were also inspected with the array. Row ten is the first row that was not stressed relieved after bending and was sampled for monitoring purposes. The total number of tubes inspected by the array in the u-bends per steam generator can be found in Table 1.

The total number of tubes inspected by the array in the u-bends per steam generator can be found in Table 1.
Bobbin coil indications of special interest were also inspected by the array probe. The indication selected for array special interest were degradation identified during the inspection (I-codes, PLP, and permeability variations), 50% of previously identified dents greater than two volts, new dents and new wvear. The number of tubes inspected for special interest per steam generator can be found in Table 1.

The number of tubes inspected for special interest per steam generator can be found in Table 1.
Preheater expansions were also inspected by the array probe. The tubes selected for the inspection include 20 %of the tubes expanded at the 17C and 18C tube support plate. The total number of tubes inspected by the array in this region per steam generator can be found in Table 1.

Page 3 of 22 Number Steam Generator Tubes Inspected Catawba Unit 2 EOC14 Tech Spec 5.6.8a (Scope of Inspection):

The following describes the scope of the Inspection performed at Catawba Unit 2 for EOC-14 in March 2006:

A bobbin coil eddy current inspection was performed at Catawba Unit 2 EOC-14 in March 2006. The tubes selected for the bobbin inspection included tubes with previous indications, tubes on the periphery of the bundle two rows deep, tubes surrounding plugged tubes and a minimum sample of 20 % of remaining tubes including all tubes not inspected with bobbin since EOC -10. During the outage additional tubes were added to the inspection plan to bound possible loose parts identified by eddy current and visual inspection. The total tubes inspected by bobbin per steam generator can be found in Table 1.

The tubesheet region was inspected with the array probe. The tubes selected for the inspection included a 20 %

random sample, all periphery tubes, all of the historical overexpansions and 20 % of the newly identified overexpansions. Relative to the latter, there was a new criterion developed to more consistently identify overexpansions. The tubesheet inspection was performed from two inches above the top of tubesheet through the tube end. The total number of tubes inspected by the array probe in the tubesheet region per steam generator can be found in Table 1.

Small radius u bends were also inspected by the array. The tubes selected include a 20 % sample of rows one, two and ten. The tubes selected by the bobbin plan in row 3 and 4 were also inspected with the array. Row ten is the first row that was not stressed relieved after bending and was sampled for monitoring purposes. The total number of tubes inspected by the array in the u-bends per steam generator can be found in Table 1.

Bobbin coil indications of special interest were also inspected by the array probe. The indication selected for array special interest were degradation identified during the inspection (I-codes, PLP, and permeability variations), 50% of previously identified dents greater than two volts, new dents and new wvear. The number of tubes inspected for special interest per steam generator can be found in Table 1.

Preheater expansions were also inspected by the array probe. The tubes selected for the inspection include 20 % of the tubes expanded at the 17C and 18C tube support plate. The total number of tubes inspected by the array in this region per steam generator can be found in Table 1.

Tubes were inspected at baffle 18 C by the array probe. This region acts as a loose parts collector since it is at the bottom of the preheater. The total number of tubes inspected by the array probe in this region per steam generator can be found in Table 1.

Rolled plugs were inspected with a rotating coil probe on the hot leg. Twenty percent of the rolled plugs installed on the hot leg were inspected. The total number of tubes with rolled plug examinations per steam generator can be found in Table 1.

All plugs wvere inspected visually on both the hot and cold leg sides. The total number of plugged tubes visually inspected per steam generator can be found in Table 1.

There are 4578 tubes in each steam generator.

Service induced degradation identified in the Unit 2 Steam Generators includes wear at support structures, volumetric wear from foreign objects, and SCC in the tubesheet region. All SCC identified during EOC14 inspection was below the H* dimension of 17" and were not plugged as allowed with alternate repair criteria approved by Tech Spec amendment #224.

Tech Spec 5.6.8.c (NDE Techniques):

NDE techniques listed below are taken from the CNS 2E0C14 Degradation Assessment and represent techniques qualified for the CNS examination. The bobbin (B) rotating pancake (Pan) and array (XP) were the only probes utilized during the inspection.

Page 7 of 22 Tech Spec 5.6.8.g (Results of Condition Monitoring, including tube pulls and In-situ test):

The evaluation was performed according to NEI 97-06 using the EPRI Tube Integrity Assessment Guidelines. The only observed tubing degradation at EOC 14 not exempted by alternate repair criteria was wear. All CM requirements were met. OA issues include a small population of tubes which were last inspected at EOC I11 and will not be inspected again until BOC 15 and growth of the wear scars left in service at BOC 14. Conservatively projected worst case depths meet the limiting 1.4 FLB structural integrity requirement of 3969 psi with at least 0.95 probability with 50% confidence. Since burst or leakage will not occur at 1.4 FLB, leakage integrity at an accident differential pressure of 2560 psi is also demonstrated.

No tube pulls or in-situ testing were performed during unit 2 EOC14.
