- The proposed change is a one-time extension of-Surveillance Reglirement 4.5.B.l.a.,. which reg 11res air testing of the drywell.and torus _ headers and nozzles once ' per 5 years to demonstrate. operability of the containment.
cooling mode of RHR. Under otirrent reglirements, which include a 25 percent grace period, the airveillances mast be performed prior to Jiane 19, 1984, 1
l-(torus) and Jiane. 22, '1984 -(drywell).. In order-to prevent a unit 'shitdown solely for. the performance of this alrveillance, we'.hereby. reglest an-extension of ' the alrveillance ' interval until-the. end of cycle 8, schediled approximately for September 1,1984.- The. extension would 1be the. eglivilant of extending the grace period from 25 to approximately 30 percent.3

GeorgiaPower d U. S. Riclear Regalatory Comnission Director of Reactor Regulation May 25,1984 Page 2 details our determination, puraiant to 10 TR 50.92, that the proposed amendment does not involve significant hazards considerations.
In order to avoid unit shutdown, it is necessary that we obtain staff review and isa2ance of the license amendment prior to the surveillance &e date of aine 19, 1984.
This win reg 2 ire an exemption from prior notice and opportunity for a hearing or for public comment under the provisions of 10 GR 50.91(a) (5).
We hereby reglest alch an exemption.
10 GR 50.91(a) (5) further states that the licensee mist explain why the emergency situation occurred.
In this case, failure to sche &le the alrveillance in a prior outage was &e to an isolated problem in the site sirveillance assigment system.
The missed assignment was not detected until it was recently identified by the fonowup tickler file maintained by the site Regulatory coupliance staff.
Due to this late discovery, we mist reglest emergency licensig relief to avoid unit shutdown.
Should an outage of alfficient & ration to perform the albject airveinance oco2r, either before or after approval of the reglested exenption, we win perform the airveinance at that time.
Enclosed along with the proposed charges is a determination of amendment class and payment of applicable licensing fees.
Riraiant to the regiirements of 10 GR 50.91, Mr. J. L. Ledbetter of the Envirorsnental Protection Division of the Georgia Department of Natural Resources will be sent a copy of this letter and all applicable attachments.
J. T. Beckham, Jr. states that he is Vice President of Georgia Power Conpany and is althorized to exeatte this oath on behalf of Georgia Power Company, and that to the best of his knowledge and belief the facts m t forth in this letter are true.

DETERMINATICE OF NO SIGNIFICANT HAZARDS 1.
One-time. extension of surveillance requirement for drywell and torus containment spray system headers and nozzles.
BASIS This change is not a significant hazards consideration in that:
- 1) It does not involve a significant increase in the probability or consequences of an accident previously evaluated. The requested one-time surveillance interval extension involves a system that is not required to meet design basis conditions.
The FSAR accident analysis does not assume operability of the system. Therefore, the slight increase in probability of potential system inoperability remaining. undetected, due to the extended surveillance interval, has no effect on analyzed accidents.
- 2) It does not create the possibility of a new or different kind of accident from any accident previously evaluated, since no new modes of operation are involved.
- 3) It does not involve a significant reduction in a margin of safety.
The margin of safety would be maintained without operability of the system.

a)
The proposed amendment does not reglire the evaluation of a new Safety Analysis Report or rewrite of the facility license; b)
The proposed amendment does not contain several couplex ismes,
does not involve ACRS review, and does not reglire an environmental inpact statement; c)
The proposed amendment does not involve. a couplex isme or more than one environmental or safety isme; d)
'Ihe proposed amendment does involve a single safety isme; namely, a one-time extension of a sirveillance interval.
e)
'Ihe proposed ' amendment is therefore a Class III amendment.
