'Ibe charge would also modify the (a) fmtnote to state that

" Suppression chamber water taperature instrumentaticn m2st satisfy the availability requirments of Specification 3.6.2.1, ACTIN c. and d." And, finally, footnote (c), which was a one-time-enly charge, is cutdated arri should be renoved.

II. REASW R31 'mE GmHGE

'Ibe pupM changes will make the Hcpe Creek Generatirq Staticn (1KES) TS regiimnt for this irstrumentaticn agree with the meiated intrumentation

. requirment of HCES TS 3.6.2.1, Suppression Ovsmber, ACTICHS c and d, with the GE Standard TS ard with the criteria of IMgulatory Guide 1.97.

III. autinnCATICH fut 'IM GANGE

'Ibe Suppression cumhar Water 'limperature instrumentation consists of two cimnnels of eight W=parature detectors each (plua installed spares) which are averaged electronically to provide two average inik water taperatures. 'Ibese can be read at several locaticos in, and outside of, the control rocan. In the event that one channel's averagirg circuit barrmaainoperable, the outputs of each of the tenperature detectors in that charnel can be read and averaged manmily and then comared to the Isamining OPERAKE channal in the cxmtrol room ard/or to Remote Shutdown Panel irdication of sqpressicn dumhar water tenperature.

'Ibe existirq HCGS TS Table 3.3.7.5-1 shows the REQUIRED CHANNEIS OIERABIE and the MDTDiM 0%NNEIS OPERAEE as the .3ame numbar, two. 'Durefore one channel's inoperability 4Mintely places the staticn in the AcrICH for 900 channel less than the MDTDU4 GANNFM OPERAEE. 'Ihis error bypasses the AcrION that would permit 7 days to restore a single inoperable channel of sw_ sicn pool temperature mcnitorirq irstrumentaticn to OPERAME status.

'Ihis specification is in direct contradicticn to HCCS TS 3.6.2.1, ACTICN c.

t III. JUSTIFICATIQi Im 11IE QWCE - Omtintxxi The current 'IS Table 3.3.7.5-1 is not in agreement with either tM GE Standani TS or Regulatory Guide 1.97, Sectico 1.3.2.c. Ecg. Guide 1.97, Table 1 lists suppression p:cl tenperature instruments as Category 2 ard Section 1.3.2.c of that guide states (for Category 2 criteria) that "Ihe out of service interval should be based cn nonnal Technical Specifications for out of service for the syntaa it servm where applicable or where specified by other requiruments".

Footrote (a) of TS Table 3.3.7.5-1 specifies that " Suppression chamber water teniperature instrumentation must satisfy the availability requixuments of 'IS 3.6.2.1." and 'IS 3.6.2.1 ACTIQi c (the 'IS for the system served by the subject instruments) requires that "With one stppression pool temperature monitoring channel incperable, restaru the inoperable channel (s) to OPDWBE status within 7 days or verify suppression pool temperature to be within the limits at least once per 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />." 'IS 3.6.2.1 ACTIQ 1 d. permits 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> to restore at least one channel of suppression chamber water temperature indication when both channels are inoperable, s ldditionally, TS 3.6.2.1. ACTIQ 1 d (8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> for rustoration) is in conflict with the IS Table 3.3.7.5-1 ACTIQ 180 requirement of rustoration within 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br />. The requested change will bring the Accident Monitoring Instrumentation TS Table 3.3.7.5-1 into agreenent with HOGS 'IS 3.6.2,1, ACTIQis c and d.

IV. 10CIPSO.92 SIGNIFICANT HA7ADIE Q1GIIMRTIGi AN71YSIS PSE&G has, pursuant to 10CFR50.92, ruviewed the proposed amentrent to determine whether our request involves a significant hazards consideration. We have determimd that:

1. The operatim of Ikre Crvek Generatim Statim (HOCS) in accordance with the pucni chame will not involve a eittnificant ircrrase in the nrtinbility or nucymnoes of an accident nrrviousiv evaluated.

'Ibe proposed amendment does not involve a physical or procedural change to any structure, cmponent or system that significantly affects the probability or consequences of any accident or malfunction of equipnent important to safety previously evaluated in the Updatal Final Safety Aralysis Report (UFSAR) . The proposal change will, in agreement with the GE Standard TS and HCCS TS 3.6.2.1, ACTION c., provide a reasonable period of time in which to restore the inoperable channel to OPERABE status while contirsuing to monitor average bulk tecperature. This proposed zwision will not affect the probability of the r m rrence of any accident and, since this proposed revision will not significantly degrade suppression pool temperature monitoring capabilities, there is to increase in the consequences of any accident or malfunction of equipmnt important to safety previcosly evaluatal, i

^

l .

2. The coeratim of 11oce Ctw* Cmeratim Statim UKUS) in accortlance with the ortocoed dmne vill not crmte the pocsibility of a new or diffemnt kinLpf amiannt frun any cruviousiv evalmted.

Them are no physical dages to the plant or to the mnner in which the plant is operated involved in the pupcm:1 revisicn. Therefore, no new or diffemnt accident is created by the proposed charge.

3. The cocratim of Hooe Crmk Cmeratim Station 0100S) in accordmoe with the muxxxd chame dom not involve a einnificant ruluctlan in a mruin of safety.

The prtposed revision will, by mkiry t.ll affecta:1 TS agtm, clarify the specifications for the plant operators. Since alternate mthods are avai' sable to detemine swussion pool ter:perature and are permitted by TS 3.6.2.1,,

ACTICH c, with one average bulk terporature dunnel inoperable, this chand can be made with no significant resultant chan,e in any mrgin of safet,y.

Ctnclusicm Based upon the above, we have detemined that this propcced change does not involve a Significant Hazards Consideration.
