Office of Inspection and Enforcement RII: VLB Region II - Suite 2900 50-321/50-366 101 Marietta Street, NW I&E Report Atlanta, Georgia 30323 85-26 ATTENTION: Dr. J. Nelson Grace Gentlemen:

Georgia Power Company hereby provides the following information in response to the violation cited in NRC I&E Report 50-321/85-26 and 50-366/85-26. The subject violation was identified during the NRC inspection conducted at Plant Hatch Units 1 and 2 by Mr. B. R. Crowley of your staff on September 9-13, 1985. The violation cited was applicable to Hatch Unit 1 only.

VIOLATION:

10 CFR 50, Appendix B, Criterion X, as implemented by paragraph 17.2.10 of the FSAR, requires, in part, that a program for inspection of activities affecting quality be established and executed to verify conformance with documented instructions, procedures and drawings.

Implementing procedures 40AC-QCX01-0, R0, paragraph 5.3.2, and 50AC-MNT01-0, R2, paragra@ 8.5.12, require that work not proceed beyond QC inspection hold points. Paragraph 8.6.1 of procedure 40AC-QCX01-0 requires that completed inspections be documented in applicable procedures, inspection plans, and QC hold point sheets. Paragraph 8.5.2 of procedure 40AC-QCX-01-0 requires that QC perform inspections in accordance with approved procedures. Implementing procedure 52IT-MNT-001-0, R0, requires that the minimum socket weld leg size be 1-1/4t where t is the nominal pipe thickness.

Contrary to the above, on September 9-13, 1985, the program for inspection of activities affecting quality were (sic) not properly executed in that:

Georgia Power d U. S. Nuclear Regulatory Commission Office of Inspection and Enforcement Region II - Suite 2900 November 4, 1985 Page Two VIOLATION: (Continued)

1. For Analog Transmitter Trip System (ATTS) ASME Class 2 welds F6709 and F6718, fitup inspection hold points were not signed off prior to welding the root passes.

2. For ATTS ASME Class 2 welds F6711, F6715, F6713, F6709, F6710, F6716, F6718 and F6713, the licensee's inspector was not aware of the 1-1/4t minimum socket weld leg size required by procedure and inspected the welds to different criteria (minimum leg size equal toheightoffittingshoulder).

This is a Severity Level V violation (Supplement I).

RESPONSE

Admission or denial of alleged violation: The violation occurred.

Reason for the violation: The failures to sign off fitup inspection hold points and to be aware of the proper weld inspection accept / reject criteria were the results of personnel errors. In the first case identified in the above cited violation, the wrong joint was signed off although the inspector's examination of the subject weld was clearly documented in written notes. In the second case, the inspector failed to adequately review the implementing procedure denoted on the weld process sheet. In both cases, the inspector failed to utilize inspection controls per procedure 51GM-MNT-012-0, Weld Process Sheets.

These deficiencies are considered to be isolated cases based on ~ a lack of attention by one inspector.

Corrective steps which have been taken and the results achieved: The documentation deficiencies were immediately corrected. As noted in the Report Details of I&E Report 85-26, ".... although the examiner was not aware of the procedure acceptance criteria, the acceptance criteria being used would insure the correct weld size for the subject weld".

Letter LR-QCX-002-1085 was issued to all inspectors to reemphasize signing off inspection documents at the time of the inspection and consulting the procedure or inspection document for accept / reject criteria. In addition, a meeting was held with Quality Control inspectors in which supervision elaborated on the details of the letter and the incident. A statement of warning was issued for any recurrences.

Corrective steps which will be taken to avoid further violations: The above actions are sufficient to prevent recurrence.
