'By letter dated ally 17,1984 (NED-84-383), Georgia Power Company .(GPC) rewested _ an - extension. of the 10 CFR 50.49(g) outage-based egripment m alification' deadline to March 31, 1985, for, the Plant Hatch Unit 2 Drywell Hydrogen ' (H )2. and Oxygen (0 2 ) Analyzers. %is extension was granted by the NRC on Algast 6,1984.- GPC hereby reglests a further extension of the

- gialification deadline.

GPC .albnitted the earlier - extension reglest die to delays which had occxtred in .the Ioss Of Coolant Accident (LOCA) environmental testing for these devices which is being performed by the man 2facturer - (Comsip, Inc.) .

GPC albmitted _what was then the latest available schedile from Cbmsip for completion of the test program as Encloalre 1 to NED-84-383. Camsip presented a revised testing schedlle to GPC on March 1, 1985, indicating that delays which had occared d2 ring and following the recently coupleted

. aging phases of the program would delay the schediled commencement -of - the LOCA testing by about six months. An outline of this. revised schedile is contained in Encloaire 1 to this letter.

GPC had previously expected to be able to declare these analyzers as fully gialified for use at Plant Hatch well before the March 31, 1985, extended 42alification deadline. However, the most recent schedlle does not

, allow an adestate period of time following receipt of the "Birty Day Interim Test Report" in which to perform the thorough engineering review

. necessary to establish gialification of this eslipment for its ' intended DR hkg

Georgia Powerkh Director of N1 clear Reactor Regulation Attention: Mr. John F. Stolz, Chief Operating Reactors Branch No. 4 March 1, 1985 Page N u se. Therefore, GPC rem ests that the carrent eosipment olalification deadline for the Unit 2 H2 and 02 analyzers be extended to November 30, 1985, under the provisions of 10 CFR 50.49(g). 'Ibe additional time reglested beyond the alrrently sche & led end of the test program will allow for any unforseen delays which calld occur & ring the qualification testing process.

GEC installed a new Comsip-Delphi H2 and O2 analyzer system on Unit 2 & ring the 1984 refueling and recira11ation pipe replacement autage.

4 Hatch maintenance personnel have been contlicting routine mrveillance and calibration of these instruments (as reglired by plant proce&res and

'Iwchnical Specifications) since the plant restarted A1 gust 29, 1984. A mmber of problems with calibration and operation of these devices have occurred, and for this reason GPC is paraling other 41alification alternatives. However, Comsip is the only H2 and O2 analyzer mamfacturer who offers environmental gialification for their instmments at this time. Therefore, the carrent GPC plan is still to use the Cbmsip-Delphi devices on both Hatch units to provide environmental gialification for this safety function by November 30, 1985.

GPC believes that the asperiority of the new Comsip-Delphi H2 and O2 analyzers over the eosipment which they replace in terms of 42alification asatrance, outweighs the problems and delays experienced d2 ring installation and testing and alpports the reglested short-term extensions of the gialification deadlines. In addition, by letter dated JL11y 24, 1984 (NED-84-395) , GPC has previously subnitted' "Jilstifications for Contimed Operation" for the plant using these instmments with incomplet.e gialification.
