Page 3 of 20 Steam Generator Tubes Inspected Catawba Unit 2 EOC14 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 wear. 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 % 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
Page 4 of 20 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 were 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.
