i NOTICE OF VIOLATION l 1

Georgia Power Company Docket Nos. 50-321. 50-366 l Hatch Units 1 and 2 License Nos. DPR-57. NPF-7  ;

During the NRC inspection conducted on October 27, 1996 through December 7.

1996, a violation of NRC requirements was identified. In accordance with the

" General Statement of Policy and Procedure for NRC Enforcement Actions." NUREG 1600, the violation is listed below:

10 CFR 50. Appendix B. Criteria III. Design Control, requires, in part, that measures shall be established to assure that applicable regulatory requirements and the design basis are correctly translated into specifications, drawings, procedures and instructions. Measures shall also be established for the selection and review for suitability of application of materials parts, equipment, and processes.

The E.I. Hatch Nuclear Plant Configuration Management Program Reference Manual establishes the policy that an ongoing Configuration Management Program for the Hatch Project will be implemented. The Configuration Management Program is designed to ensure effective control of plant changes and processes to maintain design and licensing integrity.

Procedure 10AC-MGR-015-05. Configuration Management Program. Revision 0. l establishes the responsibility and requirements for implementing the  ;

Plant Hatch Configuration Management Program. 1 Procedure 40AC-ENG-003-05. Design Control . Revision 8. establishes the requirements and responsibilities for alant design control of systems, structures and components and states t1at plant design control policy l serves to ensure that basic design criterion is maintained and revised in a planned, controlled and documented manner.

Procedure 50AC-MNT-001-05. Maintenance Program. Revision 24. establishes the requirements and responsibilities for the control of maintenance activities at Plant Hatch and states that safety related work will be i controlled by approved documents that include approved procedures and j Architect / Engineering approved drawings and documents.

Contrary to the above, configuration management and adequate design '

control measures were not implemented in that:

1. On October 20, 1996, a relief valve was installed on the Unit 2 nitrogen tank with a conflict on the proper lift setting

- specifications. This resulted in a failure to ensure that the J$ basic design criteria was maintained. Subsequently on October 28.

S80- 1996, the tank relief valve prematurely lifted. discharging oo nitrogen into the tank enclosure area. creating a hazardous '

SS condition for personnel in the area.

3d 2. During the implementation of an engineering specification 88 implementation in about 1988 for the Torus-to-Drywell Vacuum C;< Breakers an electrical connection drawing was not adequately

- changed to reflect the new installation. The inadequately changed RE electrical connection drawing resulted in the operators '

M8 unexpectedly de-energizing the 1H Torus-to-Drywell Vacuum Breaker on September 20. 1996.

Notice of Violation 2

3. A wiring error was not identified during a work verification (red-line) of a circuit following Design Change 94-044. resulting.

in a failure to maintain basic design criterion. The wiring error caused the loss of safety related 600v bus 1D, which resulted in an Engineered Safety Features actuation on April 14, 1996.

4. During the implementation of maintenance work order 1-88-7355, the.

overcurrent trip setpoint for the normal sup)1y breaker to Motor Control Center 1R24-5026 was not controlled ]y approved documents.

This was discovered on November 6, 1996 and resulted in the 1B Diesel Generator being declared inoperable for a short period of time.

This is a Severity Level IV Violation (Supplement I).

Pursuant to the provisions of 10 CFR 2.201. Georgia Power Company is hereby required to submit a written statement or explanation to the U.S. Nuclear Regulatory Commission. ATTN: Document Control Desk. Washington. D.C. 20555.
