ENCLOSURE 1 NOTICE OF VIOLATION Georgia Power Company Docket Nos. 50-321 and 50-366 Hatch Units 1 and 2 License Nos. DPR-127 and NPF-5 During the Nuclear Regulatory Commission (NRC) inspection conducted on August 30 - September 20, 1986, violations of NRC requirements were identified.

The violations were for not establishing test conditions and for exceeding surveillance frequencies required by the main control room environmental Technical Specifications (TSs). In accordance with the " General Statement of Policy and Procedure for NRC Enforcement Actions," 10 CFR Part 2, Appendix C (1985), the violations are listed below:

A. TS 4.12.A.1.a for Unit 1 and TS 4.7.2.e.1 for Unit 2 require verification of less than a 6 inches water (gauge) pressure drop across the main control room combined HEPA filters and charcoal adsorber banks while operating at the system design flow rate, 2,500 cfm +/- 10%.

TS 6.8.1.c for Units 1 and 2 requires written procedures for surveillance and test activities of safety related equipment. The procedure for the preparation and control of procedures,10AC-MGR-003-0S, Revision 4, Section 8.3.2.3.12, requires that acceptance criteria shall be contained in the text of a procedure and must include acceptance range where applicable.

Surveillance procedure 57SV-Z41-002-1, Revision 0, is the written procedure for accomplishing the above TS required surveillance.

Contrary to the above, surveillance procedure 57SV-Z41-002-1, Revision 0, was inadequate in that it did not ensure that the volumetric flow rate was at the TS required flow prior to measuring the pressure drop across the main control room HEPA filters and charcoal adsorber banks. This procedure did not provide a manometer differential pressure acceptance criterion nor a conversion method to obtain the required volumetric flow rate.

This is a Severity Level IV violation (Supplement I) - Both units.

B. TS 4.12.A.1.a for Unit 1 and TS 4.7.2.e.1 for Unit 2 require verification of the pressure drop across the main control room combined HEPA filters and charcoal adsorber banks at least once every 18 months.

TS 4.0.2.b for Unit 2 requires the frequency of each TS surveillance requirement not exceed 3.25 times the specified surveillance interval for any 3 consecutive surveillance intervals.

Contrary to the above, surveillance procedure 57SV-Z41-002-1, Pevision 0, was not performed within the TS required 18 month interval for two intervals since 1979. In addition, the Unit 2 limit of 3.25 times the 18 month surveillance interval for three consecutive surveillances was exceeded by 8610280459 861020 PDR ADOCK 05000321 G PDR

r r Georgia Power Company 2 Docket Nos. 50-321 and 50-366

. Hatch Units 1 and 2 Licensee Nos. DPR-127 AND NPF-5 more than 2 years. The last four times that surveillance procedure 57SV-Z41-002-1 was done were: September 25, 1986; October 25, 1984; March 13, 1981; and May 8, 1979. The periods of 43 months between 1981 and 1984 and of 23 months between 1984 and 1986 both exceeded the 18 months surveillance frequency of each unit. The period of 85 months between the 1979 and 1986 surveillances exceeded the TS limit of 3.25 times the surveillance interval for three consecutive surveillances by more than 2 years (Unit.2).

This is a Severity Level IV violation (Supplement I) - Both units.

Pursuant to the provisions of 10 CFR 2.201, Georgia Power Company is hereby required to submit to this Office within 30 days of the date of the letter transmitting this Notice a written statement or explanation in reply including (for each violation): (1) admission or denial of the violation; (2) the reason for the violation, if admitted; (3) the corrective steps which have been taken and the results achieved; (4) corrective steps which will be taken to avoid further violations; and (5) the date when full compliance will be achieved.

Where good cause is shown, consideration will be given to extending the response time.
