ENCLOSURE I NOTICE OF VIOLATION Georgia Power Company Docket No. 50-424, 50-425 I
Vogtle Unit 1 and 2 License No. NPF-68, NPF-81 During the NRC inspection conducted on February 28 - March 27, 1993, a violation of NRC requirements was identified.
In accordance with the " General Statement of Policy and Procedures for NRC Enforcement Actions," 10 CFR Part 2, Appendix C, the violation is listed below.
i Technical Specifications (TS) 6.7.la and 6.7.lf require that written procedures be established, implemented, and maintained covering activities delineated in Appendix A of Regulatory Guide 1.33, Revision 2, February 1978, and activities implemented in the Offsite Dose Calculation Manual (ODCM).
Regulatory Guide 1.33, Rev. 2, February 1978, delineates the types of safety-related activities that should be covered by written procedures for startup, operation, shutdown, and procedures for performing maintenance.
The ODCM describes the methodology and parameters to be used in the calculation of offsite doses due to radioactive liquids and gaseous effluents.
Procedure 35110-C, Chemistry Control of the Reactor Coolant System implements in part the ODCM.
Procedure 14805-1, Residual Heat Removal Pump and Check Valve IST and Response Time Tests-Train B, step 5.2.9, requires that RHR valve 1-HV-i 8716A be closed and independently verified to be closed.
Procedure 14612-2, SSPS Slave Relay K603 Train A Test Safety Injection, step 5.15.4, requires that equipment, including centrifugal charging pump A and B miniflow valve, 2HV-8110, be restored to the status recorded in an earlier step.
Procedure 35110-C, step 4.5.5.3, requires in part that if reactor coolant system Dose Equivalent Iodine (DEI)-131 has increased by a factor of three, change out plant vent gaseous monitor charcoal and particulate filters at least once per 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> for at least 7 days.
Procedure 13431-1,120V AC Vital Instrument Distribution System, Checklist 1, step 2.C. requires that handswitch A-HS-2532C be placed to the TEST / BLOCK CHAN II position.
Contrary to the above, procedures were not implemented as required by TS 6.7.la and 6.7.lf, in that, 9305100077 930421 PDR ADOCK 05000424 G

On March 3,1993, licensed operators failed to follow procedure 14805-1, step 5.2.9 when Residual Heat Removal (RHR) valve 1-HV-8716B was closed instead of valve 1-HV-8716A and when this error-l was independently verified incorrectly.
2.
On March' 18, 1993, a licensed operator failed to follow procedure 14612-2, step 5.15.4, when centrifugal charging pump (CCP) miniflow isolation valve, 2HV-8110, was incorrectly left closed
}
while restoring valves to their positions recorded-in an earlier j
step in the procedure.

3.
On March 16, 1993, following the Unit 1 plant shutdown when_ DEI
{
increased by more than a factor of three, chemistry technicians failed-to follow procedure 35110-C, step 4.5.5.3, when plant vent gaseous monitor filters were not changed out at the required frequency.
4.
On March 23, 1993, a licensed operator failed to follow procedure l
13431-1, step 2.c, in that, handswitch A-HS-2532C was incorrectly i
placed to the TEST / BLOCK CHAN 1 position instead of the CHAN II l
position.
t This is a Severity Level IV violation'(supplement 1).
Pursuant to the provisions of 10 CFR 2.201, Georgia Power Company is hereby.
l required to submit a written statement of explanation to the U. S. Nuclear Regulatory Commission, ATIN: Document Control Desk,-Washington, D.C. 20555, with a copy to the Regional Administrator, Region II, and a copy to the NRC i
Resident Inspector Vogtle Nuclear Plant, within 30 days of the date of the letter transmitting this Notice of Violation (Notice). This reply should be-clearly marked as a " Reply to a Notice of Violation" and should include for each violation:
(1) the reason for the violation, or if contested, the basis for disputing the violation, (2) the corrective steps that have been taken and the results achieved, (3) the corrective steps that will be taken to i
