ENCLOSURE 1 NOTICE OF VIOLATION Georgia' Power Company Docket Nos. 50-321,-50-366.

License Nos. DPR-57, NPF-5 Hatch During the NRC inspection conducted on January 24 - February 20, 1987, a

. violation of NRC requirements was identified. The violation was for a failure to adequately test the mode changing operation of air systems used ' for containment isolation : (e.g., plant instrument air / nitrogen inerting and

.drywell pneumatic). In accordance with the " General Statement of Policy.and Procedure for NRC Enforcement Action," 10 CFR Part 2, Appendix C (1986), the violation is listed below:

Unit-1 Technical Specification (TS) 6.8.1.a requires . written procedures shall be established, implemented, and maintained covering the. activities-referenced - for applicable procedures - recommended in Appendix "A" of Regulatory Guide 1.33, Revision 2, February 1978.

Appendix "A", Section 8.b of Regulatory Guide 1.33, Revision- 2, February 1978, . requires that specific procedures for surveillance -test (i.e.,

functional ' testing) should be- written concerning containment isolation i functions.

!' Unit-1 TS 1.0 definition 0 "A logic system functional test means a test- -l of all relays and contacts of a logic circuit from sensor to activated device to insure that components are ' operable per design intent. . Where practicable, action will go to completion; e.g., pumps will be started and valves opened."

i Contrary to the above, as of February 20, 1987, no procedures were established to verify the activated devices for the following cases:

, 1. There was no verification of the automatic actuation of the valves

! (e.g., IP52-F875, -F876, -F877, and -F878) to ensure the transfer of non-interruptable service air from the plant instrument air system to the nitrogen inerting system, upon loss of instrument air. The F non-interruptable service air supplied a number of primary contain-ment isolation valves specified in - TS Table 3.7-1 (e.g., IP33-F002,

-F003, -F011, and -F014).

l 2. The integrated operation of the drywell pneumatic system was not tested, although portions of this system (e.g., flow transmitter and timer) were tested. There was no verification of the automatic actuation of the drywell pneumatic system isolation valves (e.g.,

IP70-F004, -F005, -F066, and -F067) in the event of a continuous high l.

flow for greater than 10 minutes indicating a drywell pneumatic downstream header rupture.
