Attention:
Mr. J. B. Martin, Regional Administrator '
Dear Sir:
t
Subject:
Docket No. 50-361 Special Report - Inservice Inspection of Steam Generator Tubes San Onofre Nuclear Generating Station, Unit 2 a
Reference:
Letter from M. O. Medford (Southern California Edison) to G. W. Knighton (Branch Chief, Licensing Branch No. 3, U.S. Nuclear Regulatory Commission), dated April 5, 1985, with the following enclosures:
(1) Metallurgical Defects in Steam Generator Tubes, San Onofre Unit 2, April 3, 1985 (2) Steam Generator Tubing Wear, San Onofre Unit 2, April 3, 1985 Pursuant to Section 6.9.2 of Appendix A, Technical Specifications to Facility Operating License NPF-10, this report is being submitted as required by Surveillance Requirement 4.4.4.5(b) associated with Limiting Condition for Operation (LCO) 3.4.4.
This Surveillance Requirement requires that a Special Report be prepared and submitted to the Commission within 12 months following the completion of each inservice inspection of steam generator tubes. The referenced letter forwarded two detailed reports of this inspection and associated analysis.
These reports addressed tube examinations and associated corrective actions.
.During the refueling outage, an inservice full length inspection of 100*s of the unplugged tubes in both steam generators was completed on January 27, 1985.
A total of 146 tubes were plugged in Steam Generator'E2d @ 3Wd 184 tubes were plugged in Steam Generator E-089.
As required by Surveillance Requirement 4.4.4.kbT(fWesGEtA0Nfsste recently completed inservice inspection are provided in the enclosures to this letter.
Enclosure (1) is a steam generator internal location reference guide. The eddy current defect / indication locations on various esilbsures are based upon this guide.

PDR ii pSg/
o Mr. J. B. Martin Enclosures (2) through (5) provide the inservice inspection results for Steam Generator E-088.
Enclosure (2) provides a list of defects including tube identification, defect depth and the axial location of the defect in the tube. A defect is an eddy current testing indication greater than or equal to 44% of nominal tube wall thickness.
If a tube contains a defect, the tube is defective and must be plugged.
Enclosure (3) provides a list of eddy current indications less than 44% but greater than or equal to 20% of nominal tube v.all thickness.
Enclosure (4) provides a list of eddy current indications that were detectable, but quantifiable only as less than 20% of nominal tube wall thickness.
Enclosure (5) provides a list of tubes plugged after the completion of the inservice inspection.
If a tube was plugged because of an eddy current test indication in the tube, the depth of the eddy current indication is provided.
The location is provided only for batwing related indications.
Batwings are illustrated on Enclosure (1) and are i
interchangeably referred to as diagonal bars.
Enclosures (6) through (9) are listings for Steam Generator E-C39.
They are 3
i formatted identically with the corresponding list for Steam Geno ator E-088.
If you require any additional information, please so advise.
Sincerely, b
