By "05000366/LER-1984-019, :on 840924,outboard Reactor Water Cleanup Sys (RWCU) Primary Containment Isolation Valve [[SSC" contains a listed "[" character as part of the property label and has therefore been classified as invalid. Closed & RWCU Pump 2G31-C001A Tripped.Caused by Failure of Two ATTS Master Trip Units.New Units Installed|letter dated October 12, 1984]], the NRC staff rquested certain additional information for use in the review of quipnent qualification deadline extension rquests submitted by Georgia Power Cmpany (GFC).
The staff rquested that this information be submitted by October 19, 1984.
Each of the four itms of infomation rquested by the above-referenced NRC letter, followed by the GPC response to each its, are presented below:
NRC Its No. 1 Your best estimate regarding the time necessary to cmplete the installation of all quipnent currently qualified and available, based on an extension of the fall 1984 outage.
GEC Response to Its No.1 GEC estimates that with a few exceptions, installation (i.e.,
placing into service) of all replacment quipnent on the Unit 1 master list for which replacment is rquired under 10 CFR 50.49, would rquire an outage of approximately 21 weeks duration.
In addition to quipncat associated with the I+jdrogen and Oxygen Analyzer Systs which has bcen addressed in previous correspondence, we have recently identified that cmponents Ell-N002 A,B (i.e., differential pressure tranmitters) were received with an incorrect rangc.
These differential pressure tranmitters have been returned to the factory and may not be returned in time for installation during the present outage.
A listing of those itms which are not currently qualified or available, for which GIC still rquests an extension of the qualification deadline to Novmber 30, 1985 is contained in Enclosure 1 to this subnittal.

%e feasibility of empleting the insta.lation of a substantial noter of the itens for which you have requested extensions, based on an extension of the current outage, if the installation of certain ajuipnent would reluire significant delay.
GIC Response to Item No. 2 GIC has determined that as alternatives to the installation plan outlined in the above response to Itan No.1, the following three other partial installation plans would be feasible:
a)
Option A:
his option describes the scope of installation activities previously scheduled by GPC during the present outage.
In addition, subsequent to our September 11, 1984 letter describing this scope, a few additional ATIS instrments are now included in the scope of Option A due to a physical relocation of instrment l
panels.
Installation of one of the instruments will require a l
change to the Technical Specifications. A separate letter is being l
subnitted on this subject.
his plan would require an outage of I
approximately 10 weeks.
Deadline extensions to November 30, 1985 would be required for the itens listed in Enclosure 2 to this letter.
b)
Option P:
@is plan would include installation of all itens in l
Option A above, as well as a nmber of additional equipnent itens.
I Deadline extension to November 30, 1985 would be needed for all itens listed in Enclosure 3 to this subnittal.
%is plan would result in an estimated outage length of approximately 15 weeks and l
would result in the installation of approximately one-iourth of those items for which schedular relief has been requested.
c)
Option C: %is plan includes installation of all items covered by both Options A and B atove, along with a neber of additional itens. @e few items which would retuire an extension to Novenber 30, 1985 are listed in Enclouste 4 to this subnittal.
%is plan would ratuire approximately 18 weeks of plant outage time to ceplete and would result in the installation of approximately two-thirds of those itens for which schedular relief has been reiuested.

(
GPC has ' determined that replacment of more than.a very fewiof' t p r
required itms during Unit 1 operation could severaly impu::t p1Mc operability and could significantly impact plant ' safety and r*
reliability.
Ibether, see equipent installation requires work ~in areas normally inaccessible during plant operation, due to radiation l
levels.
Installation of the few ites with the plant operuting for 7
which this option is feasible would not significantly refhr:e any of tie /.
l estimated outage lengths given in the responses to It ma No. I and No.'l above.
%erefore, GPC has determined that equipunt installa: ion with the plant operating (outside of the preliminary ectivities V1ich have 7

ATTAONENT 2 E41-C002 E41-C002 is the HPCI Turbine and auxiliaries [ including E41-C002(SV1)].
The ~ HPCI Turbine _could be subjected to a harsh enviroment due to tenperature ' after a HPCI stem line break, but no credit is taken for the operation of the HPCI W rbine following a rupture of its stem supply line.
In the event of a large break IOCA for which the HPCI systen cannot maintain RPV level, the Turbine may be subjected to high radiation. However, in this case the HPCI System-is not required since the PRV will be depressurized by the break and/or the actuation of the ADS Systen. Adaluate core cooling is then provided by the low pressure ECCS systens.
In the event of a snall break IOCA for which the HPCI can maintain RPV level, the core never uncovers and hence core cooling is maintained and the radiation enviroment is not present.
'Ihis piece of equignent has been used during normal operation in plants similar to Hatch 1 for the past eleven (11) years. To date, no age related comon mode failures have been reported.
These devices have experienced relatively limited service in Hatch 1 as they have been use.d during normal operation for only five (5) years. With this limited service this equipnent is not expected to fail before replacanent.
Based on the above, continued operation is justified.
