Page 01 of 17 VIRGINIA ELECTRIC AND POWER COMPANY SURRY NUCLEAR POWER STATION UNIT NO. 1 1986 ANNUAL STEAM GENERATOR INSERVICE INSPECTION REPORT EDDY CURRENT EXAMINATION During 1986 the steam. generator tubes were examined once. This examination occurred during the June refueling outage. Tubes in "A", "B",
and "c" steam generators were examined during the outage. The material that follows presents the results of the examinations. These results include the number and extent of the tubes examined, the location and percent of wall-thickness penetration for each indication of an imperfection, and the identification of the tubes that were plugged. Also included are a "Tubesheet Cross Section Plot" (Figure 1) and "Tube Support Plate/Tubesheet Nomenclature" (Figure 2).

SUMMARY
In "A" Steam Generator there were 3339 tube examinations from the inlet side. There was one tube examined to* the seventh support plate on the inlet side, 469 tubes were examined to the seventh support plate on the outlet side, and 2869 tubes were examined full length (tubesheet-to-tubesheet). This is approximately 100 percent of the available tubes. The tubes examined were found to have a total of 120 indications that are less than 20% through wall, and 24 indications that are between 20% and 40% through wall. No tubes were found to have indications greater than 40% through wall. No tubes were plugged. Refer to the table below for details.

SUMMARY
In "B" Steam Generator there were 1608 tube examinations from the inlet side. 55 tubes were examined to the seventh support plate on the outlet side and 1553 tubes were examined full length (tubesheet-to-tubesheet).
This is approximately 48 percent of the available tubes. The tubes examined were found to have a total of 52 indications that are less than 20% through wall, 24 indications that are between 20% and 40% through wall and two indications that are greater than 40% through wall. Two tubes were plugged. Refer to the table below for details.

SUMMARY
In "C" Steam Generator there were 3342 tube examinations from the inlet side. One tube was examined to the seventh support plate on the inlet side, 467 tubes were examined to the seventh support plate on the outlet side, and 2874 tubes were examined full length (tubesheet-to-tubesheet).
This is approximately 100 percent of the available tubes. The tubes examined were found to have a total of 98 indications that are less than 20% through wall and 39 indications that are between 20% and 40% through wall. No tubes were found to have indications greater than 40% through wall. Two tubes were plugged (one for a restriction and one for indication evaluation and testing).

This examination occurred during the October refueling outage. Only tubes in "B" and "c" steam generators were examined during the outage. Tubes in "A" steam generator were not examined. The material that follows presents the results of the examinations. These results include the number and extent of the tubes inspected, the location and percent of wall-thickness penetration for each indication of an imperfection, and the identification of the tubes that were plugged. Also included are a "Tubesheet Cross Section Plot" (Figure 1) and "Tube Support
- Plate/Tubesheet Nomenclature" (Figure 2).

SUMMARY
In "B" Steam Generator there were 721 tube examinations from the inlet side. 135 tubes were examined to the seventh support plate on the outlet side and 586 tubes were examined full length (tubesheet-to- tubesheet).
This is approximately 22 percent of the available tubes. The tubes examined were found to have a total of 11 indications that are less than 20% through wall and one indication that is between 20% and 40% through wall. No tubes were foµnd to have indications greater than 40% through wall. No tubes were plugged. Refer to the table below for details.
