recommendation contained In the report cal led for ful l~scale testing to demonstrate

operab 11 lty of rel ·I ef and safety valves utl I !zed In the reactor coo I ant system of

bolling water reactors and pressurized water reactors when subjected to the full range

of expected operating and accident conditions.

The util fty owners of pressurized water reactors CPWRs) elected to implement a relief

and safety valve testfng program managed by the Electric Power Research Institute

CEPRI). The PWR owners group provided EPRI with funding to conduct the program and

•established a Safety/Rel lef Valve Subcommittee and Technlcal Advisory Group to monltC:r

EPRI activities.

As the f lrst stage of the overal I program, EPRI Initiated test Ing of rel lef· valves

under real lstlc steam condltlpns. The test! ng was conducted at the Marshal I valve I

test.facfil lty located Jn the Marshal I Steam Station on Lake Norman Jn Terrel I, North I .

Carol Ina. Duke Power cooperated extensively with EPRI Jn making the Marshall faclllty

and test operations staff available for EPRI testing, and the Initial rel lef valve

testing began Jn late June, 1980.

The primary objective of this project was to perform fut I-scale steam tests of rel lef

valves representative of those tnstal led In PWRs operated by the sponsoring utll ity ___ ,-

owners. Addftlonal objectives were to obtafn rel Jef capacity f nformatf on on each rel fef valve and to obtain prel Jmlnary Information on electrlc motor operated CEMOV>

block valve performance.

At the Marshal I valve test facll fty, saturated steam at pressures up to 2500 psfg was

•uppl fed to the valve test sectfon through the steam supply.piping leading from the

. lgh pressure steam drum of Unit 12 at the Marshal I Steam Station. The valve test section Included a relfef valve and an OOV ln-llne. The steam was passed through ..

the valve test section and was discharged through the steam discharge piping to the

atmosphere.

documented several short-term recommendations as a resul.t of the Nuclear Regu I atory

recommendation contained In the report cal led for ful I-scale testing to demonstrate

operabll tty of· rel lef and safety val_ves uttl°tzed tn the reactor. coolant system of

bot I tng water reactors.and pressurt~ed water reactors when subjected to the full range

establ I shed a Safety/Rel lef Valve Subcommittee and Technical Advisory Group to monlta-

EPRI activities.

I The tnlttal effort\at EPRI lnvolved development of a program plan to establ lsh the

I

scope and magnitude of safety and rel fef valve testing required. As soon as pref fmfnary

program requirements had been developed;. f.t ·became evident that the requirements for

a test.facility with the capability to test full-scale relief andsafety valves were

beyond the resources of mo$1" exf stl ng test facf I ftl es •.

The only exfstf ng facl I tty which met sane of toe requf rerilents ·for. the overal I test

program was lnstal led at the Marshal I Stean Station on Lake Norman Jn Terrel I, North Carol f.na, ·and was being used by Duke Power,. the pf ant owner, for rel let valve testing.

The Marshal I valve test facll fty had the capabll fty for testing valves with saturated

stean at static .pressures up to 2,500 psf g and 300,000 lb/hr. flow.· This functional

capabf 1 lty was adequate for rel lef valve testlng under steam conditions but not for

afety valve testlng since the large PWR safety valves are rated at flOi¥s near 600,000

· _of block .valves utll Jzed Jn PWRs were acquired for testing •. A llst of the OOVs tested

arid the suppl ler ls given Jn Tabl~ 1.1-1;

A sequence of valve cycles under stean conditions was defined.and designated as the

·· eval uatr on test procedure. The evaluatr on test procedure· for. EMov·s r nc I uded. f I ow

capacity tests of about one .. hal f-mlnute duration and a series of valve stroke tests

where the.valve··was cycled five times· Jn. aboµt five minutes.·· The· flow test during

the EMOV eval uatl on test was Intended to assure that the PORV f I ow was not I imlted by

the EMOV. The flow and stroke tests were fol lowed by valve leakage tests.· The

evaluatlon test procedure was conducted on each test valve and normally Involved a

.total of 21 valve cycles.

Inlet of the test section and was fabricated from lengths of 4-ln., 6-ln.,,. and 3-fn •

. pipe. The secondarystean pressurfzatJ.on line from.the high pressure ste.am drum to

the· test sectfon was 3/4-fn~ pipe. The stean supply pf ping fs shown .In Ffgure 2.1-2.

The pr Jmary stean supply 11 ne was branched from an exf stf ng safety va Ive nozz I e on

the hfgh,pressure stean drum of Unit tJ.2 with a horizontal 4-fn~pfpe. ·The hor-fzontal

pfpfng from the.safety valve nozzle contained two ·4-ln. valves. whfch permitted the

valve- test facf I fty to be. f sol ated from ·the stean supply. lmmedf ately downsjrean fran

·the fsolatfon valves, a 4-ln. by 6-ln. reducer was lnstal led fol lowed by a 6-ln. ·90°

elbow whfch dfscharged vertically. A 3/4-ln. drain. was provfd.ed In the et·bow for

condensate removal.

A 16 ft long, vertfcal 6-fn. stainless steel. pipe extended .from .the elbow at'the stean

.·. drum on the sf xth I eve I of the Marshal I Pl ant up to the seventh I eve I. Th fs vertf cal

pfpe run contained an orf f fce flow meter f nstal led accordf ng to ASME specif lcatf ons.

The 6-ln. size for the vertfcal piping was selected to reduce the. f tow vel oclty and

mlnfmfze pressure drop through the orf f Jce flow meter.

At the top of ttie vertf·cal 6-fn. pf ping, a 3-fn •. by 6..;.Jn. reducer was fnstal led and

two 90° elbows effected a-180° bend In the 3-ln. piping. A thfrd 90° elbow attac:hed

to the downward discharge I eg of the 180° bend red I reCted the pf p Ing to a hor lzontal

The t nstrumentatl on of· the test sect I on ·for the EMOV tests was I dentJ.cal to the

Tnstrumentatt on .for· the PORV tests. A dTscusston of al I test Instrumentation ts

· presented here for user ~onven r ence. ·

The test Tnstrumentattoncan be categorized tntothree-.groups. The first group of

' .. Instrumentation measured valve 'performance paraneters •. the second group monitored

. structural res!Dnse of the·test facility, and the third group provided evaluation data

for acoust·tc .. sensors. The test data presented In Section ·3 were recorded from. the

valve paraneter Instrumentation •.

The Instrumentation which measured valve performance paraneters consisted of sensors

for pressure, differential pressure, temperature, valve stem position, Initiation of

valve actuation, and operata- mota- current.

.•.. .Taps for pressure sensors were I ocated at the or If Ice f I ow meter In the steam_ supp I y

'. piping, upstrean of the PORV tn· the PORV Inlet Instrument spool, downstream of the

PORV In the ·stean discharge piping, and either on the air supply 1 lne Cal r-operated

valves) or on the pt lot discharge· I lne :Csolenotd-operated valves) to the.PORV operata-.

An add! ti ona I pressure tap was . I ocated on the second a Ir, supp I y ii ne to. the Contra I , I .

Components International CCCI) operata- when the CCI POR~ was lnstal led In th~ test

sect I on. VI sua I readout of the PORV upstrean and downstrean pressures were prov I dad

by two pressure gauges which were located near the test section. A third pressure

gauge was added ·during the Crosby, Dresser, and Target Rock PORV tests to monitor

pf I ot discharge· pressure.

·One differential pressure was measured at·the orifice flow meter.

·-----There were f Ive thermocouples mounted on the valve test sectfon and the stean discharge

pfpfng. Two thermocouples measured the temperature of the steam flow through the

Instrument spool upstream of the PORV and through the PORV out I et p Ip f ng. Three

thermocoup I es measured the surface tanperature of the I ri I et, out I et, and body of the

PORV.

Indications of valve,stan. position were recorded for both the PORV.and EMOV vat.ve

types. For PORV valves with exposed stans, linear variable dlsplacement transducers

2-11

CLVDTs) were used .to Indicate stem position •. Acoustic sensors mounted on the body of.

the valve were used to Indicate total. opening and closing valve actuation times for

. . '

' . • . . .. •,. ' Crosby and Dresser PORVs. The stem position of the Target Rock PORV was Indicated two factory-suppl led position switches which Indicated open and closed positions •.

EJVOV operata- mota- current recordings wer.e obtained to monitor EMOV v~I ve action,

and PORV event sw Itch record I ngs were obta I ned to. mon I tor PORV operator performance. ·

Flgures-2 .. 2-1 and 2.2-2 show the location of the valve paraneter Instrumentation for . . the horizontal and vertical plplng.conf lguratlons of the test section, respectively.

Structural response of the test sect! on was measured by stral n gauges, accel eraneters,

LVDTs and strain ·pins lnstal led along the test section piping and on the valve bodies.

Strain gauges provided a measurement of strain at the 4-Jn. by 6-ln. reducer, the

6-ln. 90° elbow and the 3-in. 180° bend In the. stean supply piping, and at the 8-ln •.

elbow In the stean discharge piping during all tests. One additional strain gauge . i

was mounted on the valve stem of each Westlrghouse EJVOV block valve.

!

Linear variable displacement transducers CLVDTs_) and a·. triaxlal acceleraneter measured

motion· of· the test section piping. The accelerometer was mounted on the PORV outle

flange.- LVDTs were located at the 3-ln. 180° bend In the stean supply piping, at the

PORV Inlet Instrument spool, .and at the 8.-ln. ell;>ow In the_ stean discharge piping ..

Two stral..n pins were lnstal led In the snubbers which were· connected to the 8-ln. elbow

In the stean discharge piping.

Auxll lary data were gathered during the valve tests by three acoustic senscrs lcx:ated . 0

between the orlf Ice flow meter and the 3-ln. 180 bend In the stean supply piping, on

the body of the PORV, and on the 4-ln •. Isolation valve I lne- In the steam discharge

piping. These acoustic sensor measurements were recorded to provide performance

Information on the sensors under field conditions as wel I as to provide a data base

on valve actuation characteristics.

Figures 2~2-3 and 2.2-4 show the location of both the structural response and acoustic

sensor Instrumentation for the horizontal and vertical piping conf lguratlons of the

test section, respectively. . . •

Cal rbratron of the sensors whrch were provrded by Duke Power was routrnely conducted

as scheduled rn Table 2.2-2. The sensors which were provrded by W. est.lnghouse. and Wyle. :.

were calrbrated before arrival at the Marshall test facllrty.

2.2.2 Description of Pata AcQulsltlon Systems

Data from the Instr umentatf on descr I bed in Sect I on 2. 2. 1 were recorded on str Ip charts

. and magnet! c tape dur Ing the test Ing program.

Cables from the transducers were routed from the. test sectr on on I eve I seven to the

data acqursltlon roan on level one. Figures 2.2-5 and 2.2-6 are photographs showing

exterior and Interior views of the data acquisition room.

With the exception of.the thermocouple data, the transducer signals from-the valve

.parameter Instrumentation were recorded simultaneously on strip charts and magnetic

tape. The relatlvely slower response thermocouple data were recorded on sirlp charts

only. The transducer signals from the structural response rnstrumentatfon ~nd the acoustic sensors were recorded on magnetic tape only.

I There w_ere four str Ip chart recdrders and two magnet I c tape recorders used s r mu I taneous I y

during the Marshal I valve testing program. Table 2.2-2 I tsts the Instrumentation

·recorded on strip charts and Indicates signal assignment by recorder as wel I as the

descriptions of the transducers and the strip chart recorders. The Gould 2600 strip

chart recorders were recal lbrated prior to each test. The other strip chart recorders

were cal lbrated as Indicated In Table 2.2-2. The channel assignments for the two

14-channel tape recorders varied from test to test, and Figure 2.2-7 Is a typical

channel assignment log of the transducer signals recorded by one FM tape recorder.

· The magnetl c tape recorders were reca I I brated whenever a new reel of tape was I nstal I ed.

In addition, cal lbratlon signals were recorded on the tapes as:· needed during the

testing program.

The accuracy range for.each .Instrument Is also Included lnTable2.2-2. The accuracies

given for the pressure transnltters CPT1-PT5) Include the canblned effects of I lnearlty,

hysteresis, repeatabll lty, stabll tty, and temperature. In addition to these effects,

2.3.2 Summary of Instrumentation Procedures

. Prior to each day's testing of PoRVs or EMQVs, the data acgulsltlon equipment and .the.

sensors lnstal led around the test section. were checked and appropriate cal lbratJon

and startup activities we~e performed to assure that the test data were obtained and

recorded accurately. Administrative controls for these Instrumentation p.rocedures

were pr.av I ded In the Duke Power procedure number TS-019 • "EPR I RJRV Test I nstrumentatl on

at Marshall Stean Station". These procedures are summarized below.

Before the test section was pressurized each day, al I Instrumentation piping and wiring

were checked for functional readiness •. Records for al I transducers were checked to - .

verify that the cal lbratlons were current.

If the piping for test section pressure sensa-s Pfl, Pf2, Pf3 or PT4 had been disconnected

for any. reason since previous tests, the Duke Power procedure, "Start-up Procedure

for Pressure Loops" {Attachment to TS-019), was fol lowed. Also, If the piping for

the orifice differential pressure sensor FT1 or the orifice pressure sensor PT5 had

been. d T sconnected, · the Duke Power procedure,· "Start-up Pr.ocedure for Ft ow Loop"

(Attachment to TS-019), was fol lowed.

i

The strip chart recorders were energized:. and their cal Tbratlons checked_accordlng t

procedures provided by the manufacturer and Duke Power. The FM tape recorders were

also cal lbrated and cal lbratlon signals were· recorded as required~

Al I Instrumentation activities such as cal lbratTons, problems, and equipment changes

were documented.

Fol lowing the day's testing, the test section was depressurlzed, the strip chart

recorders were de-energized, and the recorded data were documented.

• Section 3 VPJ..VE TEST RESULTS

3.0 INTRODUCTION

The fol lowing seven subsectlons detaT I the test results for each electric mota- operated

valve CEMOV> tested as part of the EPRI progran conducted at· Marshal I.

All subsections are organized In the same manner. Each subsec.tlon begins with a

description of the valve, followed_ by a chronology of the test sequence for the valve.

The test results, given next, are divided Into two parts. The f Trst part presents

the evaluation test results for the valve. Because the evaluation tests were conducted

uniformly for al I valves In accordance with the operating procedures summarized Jn

Section 2.3.1, the results are formatted Identically In al I subsections. The second

part presents the supp I ementary test resu I ts wh f ch document a I I other eye I es of the

EMOV, either before or after the evaluation test, while ft was Installed In the flershall

valve test facll tty.

The eval uatf on and supplementary test data for each EMOV were read f ram the str Ip

chart data records and tabulated on summary data sheets. In these tables the data are

presented 1 n three groups for both the open 1 ng and c I os Ing portt ons of the valve cycle

. as Indicated by "-0" and "-C", respectlve·ly. The three groups of data are: lnltlal condftlons data, valve response data and final conditions data. The Inltlal condlttons

data are those test section data recorded before valve action was lnltlated. The

valve response data quantlfy the time Interval during whlch valve actlon occurred.

The f lnal conditions data are those test section data recorded after valve action was

concluded.

The entrre valve cycle Is characterized In Figure 3.0-1 as a plot of valve stan posltlon

versus time. A typlcal plot of pressure versus tlme ls given Jn the same f Tgure.

Both dtagrans are I abeled to Indicate the tfmes l·n. the valve cycle fa- whlch test data

were Included Jn the summary data tables and Jn the dlscussfon of test results. The

lnftlal condltlons and ffnal condltlons data presented for the valve opening actfon .I ·.;.

are those data recorded at the points on the time axls labeled t 1 and t 3, respectively.

The openlng actlon valve response data were recorded Tn the tlme lnterval between t 1

The orifice pressure upsi"rean of the EMOV varied from 2375 .to 2410 pslg prier to valve

opening· and from 2280 to 2305 pslg prior to valve closing against ful I flow. Prior

to EMOV closure, the PORV· upstrean ptessuria was between 2130 .and 2150 pslg-.whlle the

PORV downstrean pressure remalned.consi"ant at 200 pslg. For the three cycles the

total opening actuation time varied.from 7.0 to 7.1 seconds while the total closing

acttiatl on ti me was con st si"entl y 7 .6 seconds. The· open Ing stroke ti me was· between 6.3

and 6.4 seconds for. each cyc1·0,. and the. cl osl ng. stroke time. was between· 7. l and 7 .2

seconds.

OPERATION 11. The eleventh operation normally consisted of one leakage test. Hot/ever,

for this.test valve, the eleventh operation consisted of a leakage test, fol lowed by a s1"roke test, fol lowed by another leakage test. The rupture disc was.relns1"alled Jn

the test sect I on before Operatl on 1l was begun. Dur Ing the f I rst I eakage test In the

operation, a leak rate of 0.0 gpm.was measured with an orlflce pressure of 2400 psfg.

Dur Ing 'the stroke. test the or f .f Tee· pressure upstrean of the EMOV was· 2400 ps r g pr for to valve openf ng and 2300 psfg prior to valve closing against ful I flow .. The nanfnal·

PORV upstrean pressure was 2140 psfg, and the PORV · downstrean pressure.was 600 psi g.

The total opening actuatlon time was 7.3 seconds, the total closing actutatlon time

was 7.4 seconds, the openf ng stroke time was 6.4 seconds, and the closf ng stroke ·tfme

was 7;.0 seconds. The second leakage test of Operation 11 was cenducted with an crlffce

pressure of 2400 pslg. A leak rate of 0.0 gpm was measured.

26. 1980 with a Rotork 14-NAl operator .suppl led by Duke Power ... The operator was set

.. at a t6rque switch settrng of 4 to. produce 110 _ft-lb torque on the valve stem which

was reC:ommended by Westinghouse In order to close the valve.

On July 1, 1980 the test Et-OV was cycled against ful I flow at 2200 pslg for the first

time. The Et-OV did not close fully. The valve position Indicator' measured a valve.

position of 30% of ful I open. At ttie 30$ open valve position, the f I ow was approx! mate I y

138,500 lbs/hr. The torque swltc.h setting was Increased.to 4-1/2toproduce130 ft-lb ..

· torque. On demand, the valve was closed agar nst f u I I f I ow at 241 0. ps I g and went to

· 28% of ful I-open- valve positl on, I.e., It only closed 72% of rated stroke. The ta-que

switch setting was Increased to Its maximum setting of 5 to obtain 170 ft-lb torque.

The EMOV was closed again against ful I flow at 2400 pslg and stopped at 22% of full-Open

valve position. The leakage flow was below the range of the ·orifice measurement, so

· an attempt was. made to do· a seat I eakage test, . but th Is test was aborted when ttie FDRV

· downstrean pressure reached 260 ps I g. The PORV was then closed to stop the I eakage.

·The EMOV was closed with no flow, and the ?ORV.was opened to do a. final seat leakage

test. The EM:>V had closed to 0% of ful I-open and showed a 0.0 gpm leak rate.

On July 8, 1980 ttie Rota-k 14-NAl operatcr was removed fran the valve and the Westinghouse

manual operator with a handwheel adapter was. lnstal led. A cal lbrated torque wrench

was obtal ned to establ !sh the requl red torque needed to close the va Ive. The test

rig was pressurized, the EM:>V was cycled twice, and a seat leakage test was performed

w Ith a resu I ting I eak rate of 0.0 gpm. The EMOV was then· opened and the. PORV was

opened to establish ful I ·flow. The -Efv'OV was closed manually against ful I flow with

the torque wrench. The readings were as fol lows:

35 ft-lb - 60% valve position

95 ft-lb - 30% val.ve position

100 ft-lb - 25% valve position

120 ft-lb - 18% valve position

125 ft-lb - 17% valve position

140 ft-lb - 12% valve position

At th Is po r nt a seat, I eakage test was conducted. A I eak rate of a.aa8 gpm was measured •.

. The. test r I g .was then . I soi ated and test 1 ng was. d I scontf nued. The· next day the

estf.nghouse valve· representative added: grease ,to the the' I as+' four threads· of. the

stem.to aid r.n closing the valve.· The test rig was pressurfzeda~d again the EMOV. was manuallyclosed with the aid of a torque wrench. There was no observed reduction

rn the required torque. The ~pp.lied torque required to fully close the valve was 11a ft~ I b.

The West I hghouse representatr ve prov I ded two we I dab I e stral.n. gauges ·to be,: mounted on

the valve stem. This. work was flnfshed on the.·valve by July 21,, and testing was . . ' . .· . . . .

continued. A.Rotork. 16-NAX1 operator-was. Iilstal led on thevalve~and was callbr.ated

·for ful I-closing. torque of 1sa· ft-lb •. · The test rig was pressurized and the EMOV was

closed against ful I flow. The valve went to the 20% of .ful 1-open_valve position.

The EMOV was closed the rest of the way by hand and a seat leakage test was performed.

Leakage readings were a.a gpm.

The torque sw Itch oil the Rotork operator was el ectr teal ly bypassed w Ith a Jumper to

al low a ful:I torque.of 240_ft-lb to be appl fed to:·the stem~ The EMOV was then cycled

·against ful I flow. The valve, opened and closed· against ful I· flow·, but blew the fuse

n the electric supply to the operator on the closing portion of the cycle.

On July 22, 1980 an attempt: was made to.cycle ~the EMOV against ful I flow. wlthout::the

Jumper rnstalledand It closed to· the 20%?f full-open·:valve posftlon. The circ1uit

to bypass the torque switch was relnstal le~ and the EMOV was partially closed to[73% ' '

of ful I open and then fuf·ly closed twice against ful I flow. A seat leakage test !was

performed with a resuittng leak rate of o.o gpm.
