E)tAMINATION

SUMMARY

In "C" Steam Generator there were 3008 tube examinations from the inlet side.

This is approximately 100 percent of the available tubes.

These tubes were examined full length (tubesheet-to-tubesheet).

Supplemental examinationa were also performed using Rotating Pancake,

0x1, and Profilometry probes where additional confirmatory or other data was desired.

The tubes examined were found to have a total of six indications that are less than 20% through wall, 153 indications that are between 20% and 40% through wall and four indications greetar than 40%

through wall.

Sixty-five tubes were plugged.

Page 1 of 6 VIRGINIA ELECTRIC AND POWER COMPANY NORTH ANNA POWER STATION UNIT 2 1989 ANNUAL STEAM GENERATOR INSERVICE INSPECTION REPORT EDDY CURRENT EXAMINATION During 1989 the steam generator tubes were examined once.

This examination occurred during the February 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.

EXAMINATION SUl&_ARY In "A"

Steam Generator there were 3237 tube examinations from the inlet side.

This is approximately 100 percent of the available tubes.

These tubes were examined full length (tubesheet-to-tubesheet).

Supplemental examinations were also performed using Rotating Pancake, 8 x 1, and Profilometry probes where additional confirmatory or other data was desired.

The tubes examined were found to have a total of three indications that are less than 20% through wall, and forty indications that are between 20% and 40% through wall.

No tubes were found to have indications greater than 40% through wall.

Four tubes were plugged.

EXAMINATION

SUMMARY

In "B" Steam Generator there were 3258 tube examinations from the inlet side.

This is approximately 100 percent of the available tubes.

These tubes were examined full length (tubesheet-to-tubesheet).

Supplemental examinations were also performed using Rotating Pancake,

8x1, and Profilometry probes where additional confirmatory or other data was desired.

The tubes examined were found to have no indications that are less than 20% through wall, and eighteen indications that are between 20%

and 40% through wall.

No tubes were found to have indications greater than 40% through wall.

Ten tubes were plugged.

REFUELING OUTAGE - FEBRUARY 1989 UNIT 2 STEAM GENERATOR "C"

EXAMINATION SUMMAftY In "C"

Steam Generator there were 3220 tube examinations from the inlet-side.

This is approximately 100 percent of the available tubes.

These tubes were examined full length (tubesheet-to-tubesheet).

Supplemental examinations were also performed using Rotating Pancake,

8x1, and Profilometry probes where additional confirmatory or other data was desired.

The tubes examined were found to have a total of four indications that are less than 20% through wall, twenty-four indications that are between 20% and 40% through wall, and seven indications greater than 40% through wall.

Fifteen tubes were plugged.

Refer to the table below for details.

2)

D.1 - Distorted Indication - a possible tube wall loss condition that is unquantifiable with a numeric percent call due to the existing signal characteristics.

3)

IHH - Indication Not Reportable - indicates that a very small tube wall loss condition exists in the data being analyzed that is below the reportable criteria threshold for this specific inspection can be used to address indications called in previous inspections that are still detectable but fall below current criteria.
