PROPOSED CHANGE TO '1HB TECHNICAL SPECIFICATIONS PhCILI'IY OPERATING LICENSE NPF-57 ilOPE CREEK GENERATING STATION DOCKET NO. 50-354 l
ref: LCR 90-08
. DES,CRIPTION OF THE C0ANGE As shown on the marked-up Technical Specitication6 (TE) pages in Attachmont.2, PSE&G _ requests that TS Surveillance 4.8.'1.1.2.h.8, A.C. Sources.--Operating, be revised by removing the following requirement:
"within 5 minutes after completing this-24 hour test, perform Suveillakce.
Requirement 4.8.1.1.2.h.4.b).**" and its associated "**" f ootnote-.
A4ditionally, Surveillance Requirement 4.8.1.1.2.h.4.b would be-modified b) revising its "*" footnote to' read:
"*This diesel generator start (10 sec) and subsequent loading (130 sec) shall-be preceded by an engine'prelube period,and operation at rated load for-one hour, or until operating temperatures have-stabilized."
i t
REASON FOR-THE~ CHANGE i
The proposed changes will provide testirg flexibility while ensuring that:
mechanical stress and wear on.the diesels are minimized. The curre.it testing requirements incorporate a level of redundancy that provides no meaningful additional test information while increasing the mechanical stresu and voar imposed on the Emergency Diesel Generators.
JUSTIFICATION FOR THE CHANGE The proposed change involves testing of the Emergency Diesel Generat'or (EDG) start and loading capabilities f rom ambient'and irom normal' operating temperatures.
Requiring that the EDG has been run and loaded for at least 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> and/or that operating temperatures have stabilized prior to performing-the-TS 4.8.1.1.2.h.4, Loss Of offsite Power test, will ensure that theisarveillance test is conducted at nominal operating ttmperatures.
Removing the. requirement that the test be initiated within 5 minutes of completing the 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> test run does not have any adverse impact on probabilities of= equipment malfunction or of any-accident.
y The current TS 4.8.1.1.2.h.6 demonstratas the EDG's ability to start and load from ambient conditions on locoro?-power in conjunction with an ECCS actuatica signal.
Initiating the loss-of-o(fpite-power-only test prescribed in TS 4.8.1.1.2.h.4 from normal oporating temperature demonstrates loss-of-power detection, raergency bua deenergization and load sheddira, diesel etart with ermanently connected loads and auto-sequencing of shutdown Joods, regardless o' the EDG's starting te iperaturer. Therefore, the redundaal p(;forstthe of this test f rom ambient conditicos (in the current TS 4.8.1.1.2.n.4) and then agair f rom porsal operating tecpes atures at the end of the current TS 1.8.1.1.2.h.8 is aQ additional cycling of the EDG's (wit.h its at te> dant mechanical stress and wear) that provides no meaningful additionn1 test information.
10CFR50.92 SIGN'FTCANT HAZARDS CONSIDI: RATION AWALYSLS PSE&G hac, pursuant tc 10CFR50.92, reviewed the prep 9 sed amendment to determine whether OLr requert involves a significant hazards consideration.
We have determined that:
The opSration__of Hope. Creek Generating Station (HCGS) in accordanco with the proposci chance will not involvq a__siJnificant increase -in the probability or consequences pf an accident or malfunction of equipment _ipporj; ant to safety a
previously evalgated.
The proposed 4teadment does not involve a pryrical or procedural change to any stracture, couponer t or system tha.t significantly af tects accident / malfunction probabilities or consequences previcts'ty ora 9" lated fra the 'Jpdated Final Saf ety Analysis Report (UFSAR).
The propose 6 changu involives the testing of the Emergency D$esel Getarator -(EDG) start and leading capabilities at normal operating temperatures.
By requirinq'tlat tae EDG han been run and loaded for at leact I hour r.n('Jor that operating tempet at ures have stabilized prior to perf orking the sta'rt an'J load tent, we easase that the surveillance test is ecoducted at noe.inal operating temper thren.
R3 moving the requirement that the test be initiated within 5 minutos of conpteting the 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> teet run does not advernely impact the probability of equipaent malfunction or that of any eccident. TU 4.0.1.1.2.h.6 &;monstrates the EDG's ability to otart f rom arabient conditions on loss-o(-power in_ cyniunction with an ECCS_ actuation sjsyyd..
Initiating the loss-ot-offsite-power prescribed in TS 4.a.1.1.2.h.4 f ecm Dormal operating temperature demonst rates loss-of-power detection, energeoey bus deenergization and load shedding, diesc' etart with permanently connected loadt, auto-sequencing of shutdown loads, etc., regardlese of the EDG's starting temperatures. Therefore, performing this tert from ambient conditions (in the current TS 4.3.1.1.2.h 4) and then again f rom norral operatisq temperatures at the end of the current TS 4.8.1.3.2.h.3 is an additional cycling of tha EDG's (with its attendant mechanical stress and wear) that provides no meaningful test information.
i The proposed revision vill provide operational testing flexibility and reduce mechanical stress and wear while ensuring the same level of emergency diesel generator performance.
