SURRY UNIT 1, SEPTEMBER 1995 RFO S/G "C", EDDY CURRENT EXAMINATION SUMMARY

In St~am Generator "C", all available tubes were inspected full length with bobbin probes. A 301 tube sample was tested with Rotating Pancake Coil (RPC) probes in the hot leg t~ansition (TSH + /- 3") region. Supplemental examinations were also perf armed using RPC probes where additional confirmatory or other data was desired. Tube R38-C74 was plugged as a precautionary measure. This Steam Generator contains a total of five plugged tubes. All NQI and NQN calls were resolved by RPC examination or history review. Bobbin signals greater than 20% throughwall may also have been subjected to further resolution by either of these methods. See the attached list for details.

1995 ANNUAL STEAM GENERATOR INSERVICE INSPECTION REPORT

• ATTACHMENT 3

SURRY UNIT 2, FEBRUARY 1995 RFO S/G "A", EDDY CURRENT EXAMINATION SUMMARY

In Steam Generator "A", all available tubes were inspected full length with bobbin probes. A 301 tube sample was tested with Rotating Pancake Coil (RPC) probes in the hot leg transition (TSH + /- 3") region. supplemental examinations were also performed using RPC probes where additional confirmatory or other data was desired. All NQI and NQN calls were resolved by RPC examination or history review. Bobbin signals greater than 20% throughwall may also have been subjected to further resolution by either of these methods. The following tubes were plugged for axially oriented indications:

Row 4 6 7 7

Column 36 39 39 50

Tube Rl-C59 was plugged as a precautionary measure due to a restriction at the tubesheet on the hot leg. This Steam Generator contains a total of seven plugged tubes. See the attached list for details.
