-REVISION OF-INTERIM COMPENSATION FOR SCHEDULAR

. EXTENSION FOR NON-0UTAGE RELATED APPENDIX R MODIFICATIONS Gentlemen:

-In letter NED-84-518-dated October 2,1984, Georgia Power Company (GPC)

-proposed ~ _ a = roving fire watch as compensation for an extension in the

' ' implementation- schedule of Appendix- R modifications for four areas of Plant Hatch. Specifically, these areas are:

-Unit 1 Reactor Building North of Column Line R7 on elevations 130'

~

o and 158' o Unit-2 Control Building Health Physics Area o Unit 2 Reactor Building North of Column Line R19 on elevation 158' o Control Building Consnon Corridor The watch,'as proposed, would have toured these four areas at least once per every thirty minutes. In the. judgement of the NRC staff, reported to GPC in

-a conversation with the NRC Licensing Project Manager for Plant Hatch, the proposed tour. frecuency ..would not provide adequate assurance of fire detection and suppression despite the other items of mitigation cited by our

. letter. In the judgement of the NRC staff, an inspection of the four areas c

every twenty minutes would provide sufficient compensation and justification for a schedule extension. Although such an increased frequency will have

' adverse impact on -personnel exposure and resource expenditure, GPC can find no other practical method of meeting the informal guidance established by the - NRCi staff for the granting of schedular exemptions. Therefore, GPC hereby proposes to establish by January 15,-1985, a- roving fire watch whose

< patrol path will pass through the four areas in question, including the Unit 1 Reactor Building " South of Column Line R-7" on the 130' elevation, at least once every twenty minutes. Upon completion of the installation of a fire protection feature, such as a sprinkler system, which complies with the NRC guidance for interim compensatory measures for a specific area, the fire watch will be discontinued in that particular area. Attached are figures outlining the general path to be followed. The specific sequence of area coverage may vary, but each area will be inspected at -an interval not l greater than twenty minutes.

With the establishment of the proposed roving fire watch, the wrapping of conduits in the Unit -1 Reactor Building South Column Line R-7 (paragraph 4.1.6, page 3, Enclosure 1 to GPC letter NED-84-444 dated September 4, 1984) proposed in - our- earlier letter is no longer necessary. That proposed mitigating action will not be taken and is hereby withdrawn from our September 4, 1984 proposal submitted for your consideration.

With the submittal of this specific information concerning compensatory measures for those non-outage-related Appendix R mo/ifict.tions that cannot be completed in the time frame allowed by 10 CFR 5L.48, GPC requests that our proposed schedular exemption be granted by NRC. The staffs of GPC and

-its consultants are available for additional discussion of these interim compensatory measures should the NRC so desire.

Should you have any questions in this regard, please contact this office.

Sincerely yours, WT &
