03/21/200306:00:00 DANIELFROST (NUD2F)It is expectedthat the bypassvalves willperform theirdesign functionduring a turbinetrip. Power iscurrently notabove 25% and theBypass valves arenot required tobe operable. ATracking LCO iscurrently openagainst thebypass valves.LCO #03-145.03/21/200313:18:34 RICHARDCUMMINS (NUR2C)Condition wascorrected whenload-set was setdown further fromindicated zero.

R11 OMAP-3submitted.03/21/200313:49:03 RICHARDCUMMINS (NUR2C)Engineering toprovideadditional inputas to likelyfailure cause.The load set wascausing controlvalves to cycleslightly, causinga responsivecycling of bypassvalves.03/21/200316:34:32 JOHNTHOMPSON (NUJRT)Engineeringobtained GETARStraces of EHCsystem parameterswhile the BPVswere oscillating.The following wasobserved:

1. BPV Demand(PID 138) wasoscillating from21.3% to 24.3% ina sine wave witha 6-7 secondperiod. A stepchange reductionof 0.6% was seenjust after eachpeak.

2. CV Flow Demand(PID 136) wasoscillating from2.6% to 3.7% in asine wave with a6-7 secondperiod. A stepchange increaseof 0.13% was seen

just after eachlow point at2.87%. The CVFlow Demandincrease precededthe BPV Demandincreases.

3. Sensedpressure (PID145) wasoscillating from928.4 psig to929.0 psig in asine wave with a6-7 secondperiod.

4. Load Set (PID148) was at 3.48%and steady.

5. Main TurbineSpeed (PID 140)was varying 0.6rpm around 1810rpm with sameperiod. Speedincreased afterthe CV FlowDemand increase.

6. CV#1 Position(PID-128) wasoscillating from1.3% to 1.9% withthe same period.Position followedthe CV FlowDemand.

The following wasrecorded afterthe Load Set wasreduced.

1. All parameterslisted above weresteady except BPVFlow Demand which

was varying about0.8% randomly.Load Set was at2.5%, CV#1position 1.6%,BPV Demand 19%,CV Flow Demand2 .5%.

Conclusions:The notch changesseen in CV andBPV Flow Demandindicate sometype of switchingaction. There isa voltagecomparator switchshown as VCP004on drawing PM003-T1-0036 thatfunctions toswitch the CVFlow Demandsignal from thespeed/loadcontrol into theBPV Amplifier A60when the signalincreases above0.00 vdc (0%demand) andswitches back outat #0.10 vdc(negativedemand). If thiscomparatorsetpoint was highand switched at2.87 vdc insteadof 0.0 vdc, aneffectivepressure setpointchange wouldoccur because theCV Flow demandwould not besubtracted fromthe BPV Demandper design until

it had alreadyincreased to2.87%. However,the BPV Demandshould have beenreduced by 11.51and this did notoccur (0.6%).

The oscillationsbegan whenturbine speed wasincreasingthrough about1500 rpm. Thisindicates theproblem waslikely to becoming from thespeed controlsection. CVoscillations arenot normal forspeed control andwould cause BPVoscillations duethe BPV Demandsummer thatsubtracts CV Flowfrom Total Flowfrom pressurecontrol. TheLoad Set outputis not the likelycause because itindicated steadyboth before andafter theoscillations andthe oscillationsshould have beenseen before 1500rpm also.

BPV-2 indicated aslower responseduring the BPVtime responsetest performedprior to startup.

This can be ruledout as a causebecause theoscillationsoccurred whenBPV-3 wasoperating.

Anotherpossibility isthe PMG powersupplies. Thesepower suppliesare energizedaround 1200 -1500 rpm andcould take overthe 30 and #22vdc buses. Thepower buses canaffect systemsetpoints ifvaried. The powersupply outputswere observed tobe normal and notin control afterthe unitsynchronized.This isconsideredunlikely.

The cause of theoscillation isunknown at thistime. The impacton plantoperation wasactually minimalas reactorpressure variedonly about 0.5psig. Speedcontrol isswitched out byPressure Controlfor normaloperations.

Recommendationsfor R11:

1. Verify thecalibration ofVCP004 FLOC H1CH-1CHXS-C363A15.2. Perform aspeed controlsimulation at theLoad Set valueslisted above andmonitor thesystem forunusual behavior.This wouldconsist ofconnectingfrequency sourcesto the speedinputs (seeHC.IC-CC.AC-0001), simulatingmain steampressure,selecting 1800rpm and observingthe CV Demandsignal.

03/18/2 00308:13:06 JOHNTHOMPSON (NUJRT)1. Description ofcondition:Hope Creek mainturbine bypassvalves selectedon the bypassvalve selectorswitch opens toapproximately 15%when the selectorswitch is rotatedto select asingle bypassvalve.

2. Impact onPlant/PersonnelSafety:

Affects operationof BPV test andwill cause BPV-1to stay 15% openduring normaloperation.

3. Requirementnot met:

BPV-1 shouldremain at zerowith the BPV Jackat zero

4. What causedthe condition tooccur:

Unknown

5. Actions takento correctcondition:Testing performedon 03/17/03 atapprox. 2000:

Rotated the BPVselector switchfrom BPV #1 thru#9. When theselector switchwas placed on BPV#1, the valve wasobserved to openapproximately15%. As theselector switchwas rotated fromBPV #1 to #2, BPV#1 remained open,and BPV #2 wasobserved to openapproximately15%. As the BPVselector switchwas rotated fromBPV #2 to BPV #3,BPV #2 wasobserved to closeand BPV #3 wasobserved to openapproximately15%. As theselector switchwas rotated from#3 thru #9, theprevious valvewould close.Only BPV #1remained openwhen notselected.

Main steam linepressure was 0psig and EHCpressure setpointwas 150 psig (atminimum) duringthe testing.

At 2230 BPV #1closed when EHCpumps wereremoved fromservice to

support troubleshooting forBPV#2. Demandsignal remainedslightlypositive, and thesame as at theend of the 2000testing.

At 2300, maincondenser vacuumwas broken.

At 2345,Operationschecked the BPV#1demand andreported thedemand is nowslightly belowzero (a changefrom slightlypositive). Thisindicates the BPVJack outputchanged slightlyand is producingthe expecteddemand signal.Loss of maincondenser vacuumremoves theoutput of the BPVamplifier to the9 BPV#s. Theslightly negativedemand is normalfor BPV#1 sinceit is the firstBPV to respond.

Voltage readingstaken on the BPVamplifierindicate the BPVJack motor driveis either notdriving farenough to achieve

0.00 vdc or thepotentiometer isbad.

NOTF# 2013600603/18/2003 16:22:57CHRISTOPHER SERATA(NUCLS)1. DESCRIPTIONDuring plant shutdownon March 17, thebypass valve responsewhen controlled by theBYPASS VALVE JACK waserratic. At one pointwith EHC PRESSURE SETin control, 2 bypassvalves fully open, andthe BYPASS VALVE JACKdemand just below thePRESSURE SET demand, atap on the BYPASSVALVE JACK INCREASEpushbutton resulted inthe #3 bypass valvepulsing from 0% to 75%open. This conditioncaused a 50# drop inreactor pressure inone minute. The dropin pressure caused alowering in coolanttemperature addingpositive reactivityand a rise in power.The power riseapproached the theAPRM upscale SCRAM of15% and caused the ROto have to range up on4 IRMs within aminute. It alsoresulted in a loweringof level from 33" to25" requiring manualcontrol to maintainlevel between the lowlevel SCRAM and thehigh level RFP tripsetpoints.

2. IMMEDIATE ACTIONSTAKENThe plant wasstabilized and theIPTE terminated.After evaluating plantresponse, a meetingwas convening. Thosepresent included theIPTE Test Manager andTest Engineer, theShift Manager andControl Room

Supervisor, theimmediate ResponseTeam manger, anda d d i t i o n a 1representatives fromthe OCC Team. Afteran evaluation of theconditions anddevelopment of aconcensus approach,r e a c t o rdepressurization wascontinued using EHCPRESSURE SET. Noadditional anomalieswere noted.

4. ADDITIONAL ACTIONSTAKENInitiated thisnotification.Discussed theperformance of theBYPASS VALVE JACK withthe EHC Specialist(NUJRT). The

specialist referred tothe BYPASS VALVE JACKperformance aserratic, and anotification toreplace the BYPASSV A L V E J A C Kpotentiometer wasinitiated.

Additional Information

1) Core Thermal Power(CTP) stayed below 25%RTP so there are noissues involvingthermal limitcompliance or effects(T/S 3.2.1 through3.2.4). Similarly, theLicense Limit on CTPwas not approached.2) Since the APRMsstayed below the scramsetpoint, there are noissues involving the:RPS system response.3) Control rodinsertions wereconsistent with theShutdown Sequence sothere are no issuesinvolving control rodmovement.4) The CTP increaseportion of this eventwas similar to anincrease in Total CoreFlow (i.e. a globaleffect) and thusviolated the 1i RTP/hrlimitation for thef a i 1 e d f u e 1reliability rules.Although this eventpotentially couldcause a furtherdegradation of thefuel defect, there arecurrently noindications ofs i g n i f i c a n tdegradation and nocorrective actions arepratical (consistentwith Appendx B of theCycle ManagementReport for post fuelreliability rulev i o 1 a t i o n s ) .Increased monitoringof the fuel defect isalready in place forthe startup due tocesium increasesfollowing both recentscrams. The changesin cesium response cannot be directly linkedto this event since it

also occurred on theprevious scram.
