ENCLOSURE 1 1

NOTICE OF VIOLATION Georgia Power Company Docket Nos. 50-321 and 50-366 Hatch Uriits 1 and 2 License Nos. DPR-57 and NPF-5 During the NRC inspection conducted on July 23 - August 19, 1988, violations of NRC requirements were identified. In accordance with the "General Statement of Policy and Procedure for NRC Enforcement Actions," 10 CFR Part 2, Appendix C (1988),theviolationsarelistedbelow:

A. 10 CFR Part 50, Appendix B, Criterion V, "Instructions, Procedures, and Drawings," requires that activities affecting quality be prescribed by documented instructions, procedures, or drawings of a type appropriate to the circumstances.

Contrary to the above, an inadequate Electrohydrculic Control (EHC) system drawing resulted in an inappropriate equipment clearance which, in turn, resulted in inadvertent closing of the Unit ?. low pressure turbine intercept valvec on August 9,1988. Drawing H-21243 did not accurately reflect the as-built EHC pump discharge piping. This inadequate drawing was used in the preparation of equipment clearance 2-88-1336 and resulted in a clearance that was inappropriate for existing plant conditions. The intercept valves were inadvertently closed when the clearance was being placed on the EHC system.

This is a Severity Level IV violation (Supplement I). (Unit 2 only) 3

8. Technical Specification 6.8.1.a requires that written procedures be

! established, implemented, and maintained for the applicable activities in  :

Appendix A of Regulatory Guide 1.33, Revision 2, February 1978. l j Appendix A of Regulatory Guide 1.33, Revision 2, recommends procedures for i operation of the turbine-generator system.

i

. Procedure 3450-N34-008-1N, "Turbine Generator Bearing Oil System,"

provides written instructions for operation of the Unit 1 turbine-l generator bearing oil system.

Contrary to the above, procedure 34S0-N34-008-1N was inadequate in that it did not provide instructions for the swapping of lube oil coolers. On April 19, 1988, operations personnel performed the swapping operation f without procedural guidance and inadvertently introduced air into the l turbine lube oil system. This resulted in a turbine trip and automatic scram in Unit 1. i 1
