1.0 PURPOSE 1.1 i,.,arpose of this report is to provide the results and su..quent conclusions based upon the analysis of preliminary steam blowdown data acquired during open-to close stroking of a prototype test valve at Wyle Laboratories during the week of November 18, 1991.
1.2 An additional purpose of this *eport is to show by conservative calculations, based on these test results, that the as installed configuration of the in plant PORY block valves is adequate to perform their-intended safety function.
1.3 The results and conclusions discussed within this report are provided so sufficient justification is available to close all remaining issues associated with NUREG 0737. Item !!.D.1 at the Fort Calhoun Station.
1.3.1 Since OPPD has not yet received the final report from the testing vendor, all data presented herein is considered preliminary, 1

2.0 BACKGROUND
2.1 Requirements for the operation of Power Operated Relief Valve (PORV) Block Valves were discussed in NUREG-0737 Item II.D.1, paragraph B.
For convenience, this peragraph is stated below:
" Block Valves--Qualification of PWR block valves is a new requirement.
Since block valves must be qualified to ensure that a stuck-open relief valve can be isolated, thereby terminating a small loss-of-coolant accident due to a stuck-open relief valve.
Isolation of a stuck-open power-operated reliefvalve(PORV)isnotrequiredtoensuresafe plant shutdown.
However, isolation capability under all fluid conditions that could be experienced under operating and accident conditions will result in a reduction in the number of challenges to the emergency core-cooling system. Repeated unnecessary challenges to these systems are undesirable."
4 2.2 In general, the nuclear industry satisfied the above requirementsby)taskingtheElectricPowerResearch Institute (EPRI with performing steam blowdown testing of various gate valves and motor actuators.
This testing was performed at Duke Power's Marshall Station in 1980.
2.3 However, the NRC expressed concern to OPPD in that the EPRI steam blowdown testing did not include the same type of gate valves and actuators that were installed at Fort Calhoun Station. Additionally, OPPD did not submit any other full size, full flow test data to demonstrate the operability of the block valves that would satisfy the NUREG-0737, Item II.D.1 requirements.
2.4 Based on these NRC concerns, OPPD committed to perform tests of anidentical(inform,fitandfunction)PORVblockvalve.
The NRC staff found this committment acceptable for meeting the II.D.1 requirements to cualify the in-plant PORV block valves by testing.
2.5 Until a suitable prototype valve could be procurred and-tested, OPPD 3erformed interim measures such as adjusting the torque switcles on the actuators to provide the maximum available torque from the motors and.to install new spring packs to allow the resulting maximum force to be applied-to the valve stems.
The NRC staff accepted these measures for providing reasonable assurance of valve operability for the interim time period until the existing block valves were fully qualified by testing.
2
4 2.6 In order to fulfill the above comittment, OPPD purchased a prototype test valve, configured a spare SMB-00 motor actuator, purcho, sed a motor and contracted with a testing facility to perform the necessary tests.

4.0 VALVE AND ACTUATOR DESIGN DATA 4.1 in order to perform the required testing, a prototype test valve was procurred from CRANE.AL0tr.0, INC., the in plant PORV block valves' original manufacturer.
This test valve was procurred under Furchase Order 5061012.
The test velve was built to the same drawings and bill of materials as the in plant PORV b1ner valves, inclJding manufacturing tolerances.
4.2 Differcnces between the prototype test valve and the in plant PORY block valves can be sumarized as follows:
.[hf1@ LX E S
^1ES1 VALVE Packing:
A:.bestus Braid O bestos with Inconel Wire Gland flange:
A351 Grace sf8H A182 Grade f316 (Casting)
(Forging)
Bonnet Clamp:
AU6 WCB A516 Grade 70 (Casting)
(Plate) 4.3 Of the above nnted differences, the valva stem packing is the only item that could posribly affect the valve stem thrust by changing the friction loading on the valve stem. However, packing friction is nore dependent upon the packing gland nut torque than on the pading type.
Additionally, valve stem packing friction load was measured separately from all other valve stem thrust parameters, thus not masking nor affecting other critical stem thrust measurements.
4.4 The inalant block valves were built to nuclear specifications while t1e prototype test valve was built to commercial grade specifications with additional self-imposed requirements (RT, UT,PT,etc.).
4J Based on the above discussion, the assumption of the prototype test valve and the in plant PORV block valves being identical in form, fit and function, is reasonable and correct.
Figure 4.1 is a drawing of the prototype test valve.
4.6 The test valve actuator was acquired from Fort Calhoun Station spare parts inventory, it was configured under Maintenaro Pork Order 911783 to make the overall actuator ratio and spring pack assembly the same as the installed motor-actuators on the in plant PORV block valves. A new motor was also installed under the same maintenance work order.
4.7 The new motor was purchased from Limitorque Corportt'on under Purchase Order C169350. A 7% ft-lb motor (as installed 5
~.
r on the in-plant PORV block valves) could not be pro:o red.
Therefore, a 10 f t-lb motor was installed on the test valo motor actuator.
Differences between this motor ard the 7 ft-lb motor will be discussed in Section 8.5 of this report.
4..' A different stem lubricant was used on the test valve tha, what is currently being used on the in-plant PORV hlock va vos.
ihis was done as the new lubricant will be used oa the in viant valves beginning with the 1992 refueling outtge.
Diiferen.es between the stem lubrication will be discussed in Sec+1on 8.5 of
}
this report.

5.0 VALVE BLOWOOWN TESTING 5.1 Selection of Test Vendor 5.1.1 WYLE Laboratories in Norco, California was selected as the test facility to perform the blowdown testing under Purchase Order 5067877.
5.2 Test Loop Configuration 5.2.1 The steam test loop was configured so pressure losses during steam blowdown conditions could be matched as closely as expected to the in-plant steam blowdown conditions.
This was accomplished by evaluating the in-plant PORV piping arrangement from the pressurizer up to and including the PORY and configuring the steam test loop accordingly.
5.2.2 After evaluating the in-plant piping arrangement, the following piping configuration requirements were dictated to the test facility:
5.2.2.1 Piping upstream of the test valve to the steam accumulator shall have an effective resistance coefficient of 4.6.
5.2.2.2 For flow stabilization and instrumentation considerations, the pipe shall be 2 inch, Schedule 160, for at least 10 pipe diameters upstream of the test valve.
5.2.2.3 For flow stabilization and instrumentation considerations,hpingdownstreamofthetest i
valve shall be 2 inch, Schedule 160, 2 feet long.
5.2.2.4 Installation of a PORV or equivalent valve / orifice combination with a flow area of
.00553sq. feet (1.094inchesdiameter) downstream of the test valve.
5.2.2.5 Piping downstream of the PORV or valve / orifice combination shall be 4 inch size for a minimum length of 5 pipe diameters.
Beyond this point, any larger pipe size may be used.
5.2.2.6 The resulting steam test loop configuration is shown in Figure 5.1.

6.0 STEAM BLOWOOWN TESTING RESULTS 6.1 Steam blowdown testing was conducted in accordance with the system configuration and steam conditions, with the exception of steam flow, as discussed in previous sections of this report.
F6gures 6.1 through 6.4 show the results of the actual blowdown testing with the test valve going from full open to full closed.
6.2 Actual maximum steam conditions obtained during the testing are shown in the table below and based on calculations discussed in Section 7.0 of this report.

However, the design steam flow rate of the PORVs was exceeded.
Therefore, the steam flow conditions were considered conservative and therefore acceptable.
6.4 In order to determine the test valve's stem thrust requirements, raw data taken at 100 Hz intervals for approximately the last 30% of the test m1ve stroke was analyzed.
This raw data is tabulated in Appendices A through 0 of this report.
6.5 Figures 6.5 through 6.8 are the resulting valve stem thrust 1
plots taken from the instrumented load washers on the actuator upper bearing housing for the last 30% of valve stroke.
Analysis of these and steam flow plots clearly show there are three distinct points of valve performance to be examined.
Thesepointsare1)flowisolation,2)pressuresealand3) valve disc wedging.
6.5.1
" Flow isolation" is the point where steam blowdown flow is stopped.
It occurs prior to valve upstream pressure isolation.
The point of flow isolation was determined where the flow venturi differential pressure became "zero".
This zero flow point was also verified by comparing the measured venturi upstream pressure to the measured test valve upstream pressure. Flow isolation occured where the differential pressure between these two measured )ressures became zero.
It is important to no% t1at the valve disc is not fully seated at this point. This appears to be a significant valve design attribute.

__i
6.5.2
" Pressure seal" is the point where the valve upstream pressure is " sealed" or isolated from the downstream side of the valve.
This point was conservatively determined from the raw data where the valve downstream pressure was effectively zero.
Verification of this pressure seal point was where a change in slope occurred in the stem thrust plots prior to valve disc wedging.
Again the valve disc is not fully seated at this point in the valve's closing stroke.
This is also a significant valve design attrribute.
6.5.3 " Disc wedging" it se point where the valve disc is fully inserted into the valve seat but has not been " wedged" in place.
This wedging was identified as the instant just prior to the essentially vertical section of the valvestemthrustplot(asshowninFigures6.5through 6.8).
6.6 It is important to realize that the instrumented load washers show only the valve stem thrust developed above valve stem packing friction load.
This valvo stem thrust developed above stem packing friction load is what is needer' to be analyred for valve opera)ility concerns since +.his is the developed stem thrust needed to overcome the fi id forces caused by the steam flow and differential pressure.
6.7 for all valve strokes, valve stem packing friction load was measured by valve stem strain gauges and determined to be constant at 1500 lbf.
6.8 Table 6.1 is a summary of the resulting acquired valve stem thrusts (includinastempackingfrictionload).
In order to coinpare this measured data with expected valve stem thrusts at the steam blowdown test conditions (using the various industry equations), figure 6.9wasdevelopedtoshowthiscomparison.
As can be seen by this figure, the test valve reouired sianificant'v less stem thrust to successfully stop and isolate the steam b'owdown flow than what had been predicted by the industry equations.
6.9 An interesting phenomenon observed during blowdown testing at 2000, 2250 and 2500 psi, was a reduction in measured valve stem thrustsat43%ofvalveopen(goingfromfullopentofull closed).
This phenomenon was also observed durin theIdahoNationalEngineeringLaboratory(INEL)gsomeofvalve testing and has been explained as follows:
6.9.1 As the valve is going closed and reducing the flow area through the valve bore, the reduction in flow area causes areductioninpressurebelowthevalve-disc (venturi effect).
6.9.2 All through the valve s' oks, valve u) stream pressure exists in the valve bonnet cavity. Tais bonnet cavity pressure is attempting to push the valve stem out of the 11
valve body.
This-is generally referred to as " piston effect" or " stem rejection load." However, this bonnet cavity pressure is also pushing on the top of the valve disc.
6.9.3 When the pressure below the valve disc drops to a certain-value, the force caused by the differential pressure from the top of the valve disc to the bottom of the valve disc overcones the " stem rejection load" and aids in closing the valvo disc.

7.0 DATA ANALYSIS 7.1 Apparent Valve factor Determination 7.1.1 in order to utilize tne acquired raw data to resolve the in-plant PORY block valve operability concerns,
" apparent" valve factors were calculated for the test valve at flow isolation, pressure seal and disc wedging for the various steam blowdown test pressures.
7.1.2 These apparent valve factors (AVFs) were determined using the equation below from Reference 10.5, which is derived from the classic form Uf the industry valve stem thrust equation for gate valves going in the closed direction.
The word " apparent" is used becsuse it is assumed the valve stem thrust agi due to valve stem packing friction loads or stem rejection loads is due solely to friction between the valve disc and disc guides / seats.
Fs - (P A) s DP AD where: AVF - Apparent Valve Factor F
- Heasured Valve Stem Thrust (lbf) 3 DP - Heasured Valve Differential Pressure (psid)
A
- Cross-sectional Area of the Valve Stem (in )
2 s
P - Measured Test Valve Inlet Pressure (psig) 2 AD - Valve Disc Area (in )
7.1.3 F, DP and P were taken directly from the acquired 100 s
Hz raw data-(Appendices A through D). A and AD are 3
based upon valve geometry. The valve disc area (A ) is based on the mean contact diameter between the D
downstream valve disc and seat. This diameter was obtained from a dimensional inspection at the CRANE manufacturing facilities prior to the test valve final assembly.
For convenience and clarification, this measurement location is shown in Figure 7.1.
7.1.4 Since the test valve was not marked as to the direction of flow (immaterial for gate valves), it was not clear as to which "mean seating diameter," as measured by CRANE, to use in the AVF determinations. Therefore, for conservatism, the calculated AVFs were maximized by using the smallest measured "mean seating diameter."
13 l
7.1.5 Table 7.1 shows the results of the determination of AVFs for flow isolation, pressure seal and valve disc wedging.
7.2 Steam Flow Rate Determination 7.2.1 The determination of a maximum steam flow rate for each test run was calculated by the following formula:
SFR=12,063.(VDP)h-(RHO)b where:
sFR
= Steam Flow Rate (ibm /hr) 12,063 = Venturi Flow Constant V0P
= Corrected Flow Venturi Differential Pressure (psid)
RHO
= Density.ofSteamattheMeasurgdFlow Venturi Inlet Pressure (lbm/ft )
7.2.2 Flow Venturi Differential Pressure was "zero shift" corrected to obtain a maximum flow rate.
This zero shift correction was obtained from static test valve strokes at the pressures of interest.
7.2.3 The steam density (RHO) was calculated using-the following formula generated by the testing vendor.
This formula for steam density is based on a "best fit curve" from standard steam tables for the steam pressures of interest.
[a+c-(P1)+e-(P1)2]
RHO =
[1+b-(P1)+d.(P1)2]
where:
P1 = Measured Flow Venturi' Inlet Pressure (psig) a = 3.38956 E-6 b = -0.0003156853 c = 0.0019975794 d = 1.3587223 E-8 e = -4.3731674 E-7 7.2.4 Table 7.2 shows the results of the calculated maximum steam flow rates used during the blowdown test runs.

7.3 Appendices E through H show the resulting plots taken from the raw data generated for approximately the last 30% of test valve stroke.

8.0 APPLICATION OF TEST VALVE RESULTS TO IN-PLANT VALVES 8.1 Safety Function Operation 8.1.1 Because of the unique operating / design characteristics of the test vah e and the in-plant PORV block valves, tre point of " pressure seal," as determined from the,open to close valve stroke data, was considand to be where the valve completely isolated steam blowdown flow.
8.1.2 Because of identical valve designs, this pressure seal valve position is considered to be applicable to the in-plant PORY block valves.
8.1.3 Therefore, the valves' motor operator must be able to provide enough valve stem *.hrust to close the valve to the pressure seal position for the valve to satisfactorily perform its safety function of isolating steam blowdown flow.
8.1.4 The use of the pressure seal valve position is considered to-be valid for safety function operation because of th. following:
8.1.4.1 PORV block valves are not considered containment isolation valves and therefore do not have to be
" leak tight" as would be applicable at the valve disc wedging position.
8.1.4.2 The design and performance characteristics of the test valve promotes pressure sealing / pressure isolation nrior to full valve disc wedging.
8.2 Determination of Worst Case Valve Factor 8.2.1 In onbr to perform an in-plant PORV b1' 3 valve ops < dity evaluation, a " worst case" valve stem thrust anJ pparet" valve factor must be determined.
8.2.2 The load washers used to measure the test valve stem thrust in the closing direction have a vendor stated total inaccuracy of + 14%.
Applying this inaccuracy to the measured pressure seal' valve stem thrust (and neglectingstempackingfrictionloads)fromtimepoint 206, for the 2500 psig steam blowdown test run,-results in:
(TotalStemThrust-PackingLoads)X1.14=WorstCaseStemThrust (4590 - 1500) X 1.14 = 3523 lbf 16-
i, 8.2.3 This value of 3523 lbf is the worse case stem thrust reauired above the valve stem oackina friction load for propersafetyfunction(isolatingsteamblowdown flow at 2522 psig/2518 osid) operation of the test-valve.
8.2.3 Pressure and differential pressure measurements have an inaccuracy of 1 0.25% of 3000 psig (1 7.5 psig).
In order to maximize the apparent valve factor calculation, the valve inlet 3ressure and differential
)ressure must be minimized.
T1us, at the maximum steam alowdown conditions for pressure seal (time p int 206 for the 2500 psigsteamblowdowntestrun),thevalveinletpressure and valve differential pressure could have been as low as:
Valve Inlet Pressure:
2522 psig - 7.5 psig = 2515 psig Valve Differential (2522psig-7.5 psi))=2503psig (4 psig + 7.5 ps g Pressure:
8.2.4 Utilizing the formula for determining apparent valve 4
factors (Section 7.1.2), applicable test valve geometry parameters, the above worst case valve stem thrus', of 3523 lbf, minimized valve inlet pressure and vsive differential pressure results in a worst case aonarent valve factor of:

l-8.3 Required Valve Stem Thrust of In-plant Valves 8.3.1 In order to determine the-required actuator output stem thrust at the design basis condition : established in Section 3.0, the stariard ve.lve equation will.be conanined with a conservative apparent valve factor.

8.3.3 Since no iaeasun ments dave-been =taken on the in-plant PORV block valves, the no M 1 "mean" seat-diameter and valve stem diameter, ass

Stem Olameter =-1.125 in.
2 As = 0.994 in 8.3.4 To account for' aging and_ wear differences between;the Lin-plant valve and:the test valve, the. apparent valve-factor will be increased from 0.081-to a value of 0.1.-
This is considered conservativa since the in-plant valves-have never been operated under a steam blowdown differential-pressure situation.--Therefore material wear is considered minimal. -Additional'y, the worst case valve factor is already-based upon steam conditions r
greater than.the-design basis-conditions.

8.3.3 Substituting the apprapriate values into the above required stem thrust equation results in the following requi cd stem thrust:
F3 = (0.1 2485 5.39) + (2485 0.994)
F3 = 3810 lbf 8.3.6 This valua of 3810 lbf is the valve stem thrust, above the ste:n packing friction load, required for valve operation at design basis conditions, 8.4 Evaluation of Preiiotn MOV Test Data 8.4.1 (o show that an MOV has sufficient capability to operate e va'.ve at the design basis cond'tions, the total measuredva'Ivestemthru,tattorqueswitchtrip(TST),
including instrument inaccuracies and " rate-of-loading" effects penalties, must be greater than the
.I valve stem thrust required for the valve to perform its safety function under differential pressure conditions.
8.4.2 The last LOV test data packages for the in-plant PORV block salves were examined and the following valve thrusts were noted:
I VALVE TAG THRUST AT TST PACKING LOAD HCV-150 7200 lbf 360 lbf HCV-151 7650 lbf 700 lbi 8.4.3 It should be noted that the packing loads identified in the last diagnostic tests are not "true" packing-loads but are rather " running loads." These running loads occur during the entire valve stroke and include stem packing friction loads.
It is not possible to quantify valve stem packing friction loads using the M0 VATS test methodology in use at Fort Calhoun Station.
8.4.4 The test valve exhibited a 30% reduction in thrust output-atTSTunderdynamic(blowdown)testconditionsas compared to static (no-flow) test conditions. This is commonly referred to as a " rate-of-loading" effect.
8.4.5 For the above noted valve stem thrusts, a test equipment inaccuracy of 7.6% will be utilized to show a " worst case" stem thrust measurement.

_____.___.__.___--.m_
8.4.6 To determin, the value of stem thrust at TST considering
" rate-of-loading" effects and test equipment inaccuracies, the following application of these penalties will be utilized:
Measured Stem Thrust at TST - 7.6% - 30% - Packing Loads = Corrected Stem T.hrust 8.4.7 The corrected stem thrusts for the in-plant PORV block valves are as follows:
VALVE TAG CORRECTED STEM THRUST HCV-150 4297 lbf HCV-151 4248 lbf 8.4.8 When comparing these corrected valve stem thrusts to the calculated reouired stem thrust of 3810 lbf, it is clear that margin exists at TST for satisfactory operation of the in-plant PORV block valves to isolate steam blowdown flow at design basis conditions.
8.5 Comparison of Test Valve Motor and Lubrication to In-plant Valves 8.5.1 There are two differences between the test valve and actuator and the existing in-plant PORV block valves and their actuators.
8.5.1.1 The test valve had a 10 ft-lbf motor installed on its actuator while the existing motors on the in-plant PORV block-valve actuators are 7%
ft-lbf motors.
8.5.1.2 The test valve stem lubricant was Mobilux EP-1 grease while the existing stem lubricant on the in-plant PORV block valve stems is Never-Seez NG-165.
8.5.2 To evaluate hese differences, the following analysis was performed.
8.5.2.1 Applying the worst _ case valve stem thrust (3523 lbfasdiscussedinSection8.2.2)andincluding the constant measured stem packing friction load of 1500 lbf results in a total worst case measured test valve stem thrust of 5023 lbf.
20
~
8.5.2.2 To calculate the required motor torque to operate the valve at this stem thrust value, Limitorcue Corporation's-sizing procedure was utilizec.
8.5.2.2.1 Valve stem thrust is converted to torque by the usa of a " stem factor" (SF).
Its application follows:
Required Stem Thrust SF = Required-Stem Torque 8.5.2.2.2 A stem factor of 0.0158 was utilized-in the conversion of-stem thrust to torque.
8.5.2.2.3 This stem factor value is based on na lu'urication for a bronze actuator stem nut rotating on a-1.125--inch diameter steel valve stem with a pitch of and a lead of-.
8.5.2.2.4-Using this-stem factor with the required valve-stem thrust results in a required actuator stem torque output.of:
5023 lbf. 0.0158 = 79.36 ft-lbf-8.5.2.2.5 To calculate the required motor torque for this actuator output:
stem torque, the following formula was-used.
I Required Motor Torque =

where POE = Pullout Efficiency (0.4-for these.

21
.1
o 8.5.2.2.6 Substituting the appropriate values results in a required motor torque oft Required Motor Torque =
(0.4) (O.
6.8)(1.0)2 Required Motor Torque =
4.71 ft-lbf 8.5.3 When comparing the required motor torque of 4.71 ft-lbf to the available motor torque of 7 ft-lbf as exists on the in-plant PORY block valves, it is clear that a7 ft-lbf motor could have successfully o)erated the test valve. 'Thus, the use of a 10 ft-1)f motor on the test actuator is-acceptable.
8.5.4 When petforming the above calculation, it is significant that the required valve stem torque was determined assuming a lubrication between the actuator stem nut and valve stem.
Thus, the lubrication differences between-the test valve and the in-plant PORV block valves are acceptable since both-the Never-Seer and the Mobilux EP-1 do provide soam lubrication while the calculation assumes a lubrication.
8.5.5 To ensure the-in-plant PORV block valves' actuator motors are sized-appropriately, the calculated required valve-stem thrust (3810 lbf) is added to the highest measured
" packing loadd (700lbf)from-thelastMOVdianostic test.- This results-in a total. thrust of=4510 bf.
8.5.5.1-This-total thrust is less than the 5023 lbf used--
in the above evaluation. Therefore, the.
I in-plant 7 ft-lbf-motors are adequately sized.

9.0 CONCLUSION
S 9.1 Based on the discussion provided in the previous sections of the report, it can therefore be concluded:
9.1.1 The test valve and actuator accurately modeled the m
in plant PORY in performance characteristics.
9.1.2 The steam blowdown test conditions exceeded the maximan design basis conditions for the in-plant PORV block valves and are therefore conservative and acceptable.
9 9.1.3 Based upon a conservative analysis, the in-plant PORY block valves have margin at actuator torque switch trip to perform their safety function of isolating steam blowdown flow through a " stuck-open" PORV.
9.2 Based on these conclusions, the in-plant PORV block valves will stroke closed in 10 seconds (or less) under the maximum expected differential pressure and flow conditions and therefore meet their most severe design basis function. As a result, all remaining NUREG-0737, Item II.D.1 issues have been addressed by this testing.
