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. | |||

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.

- ATTACHMENT 1 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. 1

ATTACHMENT 3 VIRGINIA ELECTRIC AND POWER COMPANY SURRY POWER STATION UNIT 2 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 Column 4 36 6 39 7 39 7 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. 1

- 1. ROW, COL COLUMN tube identifier numbers an X-Y coordinate system.
- 2. IND INDICATION Character codes and numerics that represent the analysis results of the data for that tube, e.g., SIA, 25%, etc.
- 3. LOCN LOCATION The location in the tube of the INDICATION called.
- 4. MAI MULTIPLE AXIALLY ORIENTED INDICATION - Describes multiple axially oriented indication signals from rotating Pancake Coil probe data.
- 5. NQI NON-QUANTIFIABLE INDICATION - A call to identify a bobbin probe signal that is >40% through wall and requires a RPC test to for final disposition.
- 6. NQN NON-QUANTIFIABLE INDICATION THAT DIDNT CHANGE FROM HISTORY - A NQI call that was looked up in past outage data and found to have had no change.
- 7. 55 A number in the indication column shows the% through wall depth of the indication.
- a. RST RESTRICTED - Indicates that the probe listed in the record would not physically pass the location specified.
- 9. SAI Describes a single axially oriented indication signals from Rotating Pancake Coil probe data.
- 10. UDS UNDEFINED SIGNAL - a signal that in the analyst's opinion does not at present represent tube wall loss - the signal is reported for future review purposes
- 11. DSI DISTORTED SUPPORT INDICATION - a possible tube wall loss condition that is unquantifiable with a numeric percent call due to the signal characteristics and is located at a support plate.
