The examination was conducted utilizing the multifrequency eddy current technique. The program was as follows:                                            >

1. Cold leg examinations were performed from the seventh support plate on the hot leg side through the tube end on the cold leg side on rows 2 through 46, row I -

tubes were ' examined from the seventh support plate on the cold leg side through the tube end on the cold leg side. These examinations were completed using magnetically biased 0.720 inch, 0.700 inch and 0.680 inch diameter bobbin probes.

2. Hot leg examinations were performed from the seventh support plate on the hot le'.;

side through the tube end on the hot leg side. These examinations were comn'eted using magnetically biased 0.720 inch diameter bobbin probes, All row 1 U-Bends were examined from the seventh support plate on the cold leg sido through the seventh support plate on the hot leg side using Zetec dual motion MRPC U Bend probes. Motorized rotating pancake coil (MRFC) techniques wer:, utilized extensively in both steam generators.. The inspection strategy was to examine all row 1 U-Bends and supplement the bobbin coil data to further characterize: indications of percent through wall, manufacturing burnish marks, undefined indications and distorted indications. The'following is a summary of MRPC examinations: 93 U-Bends examinations in 11 hot leg 71 U-Bends examinations in 12 hot leg 100 supplemental examinations in 11 het leg 32 supplemental examirations in _11 cold leg 168 supplemental examinations in 12 hot leg 25 supplemental examinations in 12 cold leg Conam Inspection was-contracted to acquire and evaluate the eddy current data. Zetec was , contracted to perform a completely independent evaluation of all_ data acquired

- by Conam Inspection. The scope of all -the work contracted was completed using remote positioning devices and the Zetec MIZ-18 digital test equipment along with as-sociated acquisition software. The-analysis was completed using Zetec, Inc. EDDYNET version 2J with ANALYSIS program revision 1H released 5/29/91, RPC program revision lE released 5/29/91 and CRACKMAP-program revision-0G released 5/29/91.
