Operability Analysis and Test PURPOSE h purpose of the operability analysis is to demonstrate by a combina-tion of analysis and testing that the referenced valve and actuator meet the following requirements.

1. h available actuator torque must be twice that required at all angles of disk opsmimt when considering valve differential pres-sures of 48.4, 24.2, and 0 poi.

2. h actuator torque pMM by the actuator spring alone must be

, twice that required to close and seat the valve with no flow assist.

3. Valve and actuator stresses critical to operability must have a ratio of allowable to actual stress equal to or greater than two.

Stresses will be r=1mfated based on the worst case torques / loads.

PROCEDURE h theoretical torque analysis for requirement neber 2 above and an analysis of valve and actuator stresses for requirement nimber 3 above were perforined in the operability pre-analysis (Appendix A of this report).

Operability tests were perforined to verify the torque requirements of the valve and the torque capability of the actuator.

n e detailed stress analysis and/or static deflection operability test required to qualify the valve and actuator are included in the valve Design Report which will be issued at a later date.

Environmental qualification of the valve seat is by test. A Qualifica-tion Test Report will be issued at a later date.

We operability tests were perforised on valve serial number V34752-048-1.

10RQUE REQUIREMENT

% e torque required to operate the valve consists of three components.

a) Dynamic Torque b) Frictional Torque c) Seating Torque (occurs at 0 degrees open)

l In the operability g . r lysio the marimam torque required to operate the valve as asstmed to be 7351 in-lbf, which was the estimated seating plus i i frictional torque at the fully closed position. h stress analysis in the operability pre-analysis m port was h==ad on 7351 in-lbf.

Operability tests were performed to verify the dynando, frictional, and seating torque, and to verify that the actuator would produce the torque required to operate the valve, including a 2-to-1 margin.

TOREJE MEASUREMENT PROCEDURE h dynamic, frictional, and seating torque, and actuator torque output were all measured by means of strain gases attached to the valve shaft. Two strain sages were placed diamatrically opposite each other on the valve shaft approximately 1.75 inch down from the top of the actuator yoke.

A data acquisition / control smit was used to read the strain sages and calculate the correspnndinn torque on the valve shaft. Both the excitation and the ir-had voltages were monitored. Each torque measurement consisted of two raading= of excitation and induced voltages. A sample of the data is

shown in Figure 1. h time and date of the measurement are printed for reference. Actuator pressure (P) and disk position (% rot) are both input by the operator and printed for reference only. h y do not affect the torque calculation. He values of shaft diameter (D), Poisson's Ratio, endulus of elasticity (E), and strain sage factor which are used in the torque calcula-tion are printed for reference. Next, the data for each of the two raadings are printed. Excitation voltage is ei, irwhead voltage is eo. h calcu-lated strain, shear stress and shaft torque are printed. h polarity of the calculated strain is such that a positive torque indicates the actuator is tending to open the valve, opposed by friction or dynamic torque as the case say be.

At the start of each test the strain sage bridge was zeroed at a known j operation condition (usually while the valve was streking open with no flow through the valve). Torque measurements were made with the valve stroking open and closed to establish a frictional hysteresis null value. his null value, which is the average of the opening and closing frictional torques, was subtracted from each torque reading. In the case of dynanic torque measurements, the frictional torque and null torque were eliminated by the method used to perforin the calculations.

Seating Torque h valve seat was installed in the valve and the valve was installed between flanged fixtures. h valve was opened to 100% open and the strain sage bridge was zeroed. H e null torque reading was established as -515 in-

-lbf.

h valve was allowed'to stroke closed several times while the induced voltage from the stain sages was monitored to verify that the maximum seating

. torque does indeed coeur when the disk av=== to a stop against the seat.

He valve was opened and allowed to close due to the actuator spring torque only. A seat leakage test was performed to ensure that the disk was fully closed: leakage was zero bubble per minutes at 54 psig.

h valve was opened and closed (by spring only) six times. After each closure, the shaft torque was measured. h average of the six tests, corrected for the null torque raarHng, was 4403 in-lbf. His value includes both seating torque and frictional torque.

h required actuator torque to close and seat the valve is therefore 8806 in-lbf, including the 2-to-1 margin.

DYNAMIC '!UGUE PREDICTION

REFERENCE:

Floyd P. Harthtm, ' Effects of Fluid Compressibility on Torque in Butterfly Valves,' ISA Transactions Vol. 8, No. 4, p. 281.

S e valve specification requires thit the valve actuator be able to produce at least twice the torque requin d to operate the valve. Se torque required to operate (stroke), but not seat or unseat the valve, consists of two components: dynamic and frictional.

%e dynamic torque (Te) is caused by fluid reaction forces acting on the valve disk. h e friction torque (T,) is caused by bearing friction.

H e dynamic torque can be determined experimentally from tests conducted with water flowing through the valve. However, the dynamic torque due to compressible flow (r.ir or steam) will not be the same as the dynamic torque predicted by a test using water. The ISA paper referenced above contains a method to predict dynamic torque due to compressible flow once a test has been performed with incompressible flow.

Two equations from the ISA paper are used Ka = To/D8^P (test with incompressible flow) (1)

Ts ' = Ka D8 Pa (Ca C /59.64)8 Sint8 (2)

Page 6 of 20

In equation (1), To and AP are dynamic torque (in-lbf) on the valve disk and pressure drop (psid) through the valve measured during a test with water flowing through the valve. D is the disk diameter (inch). E is the dimensionless torque coefficient which relates torque to pressure drop. E varies with disk position and must be =1 & 1=ted at different disk angles.

In equation (2), To ' is dynamic tortpe (in-lbf) due to compressible flow through the valve when upstream pressure is Pi (psia) and disk angle is 9 (closed = 0, open = 90 degrees). S e factors C and Cs are used in a particular valve flow sizing equation. C is a correction factor for variation in specific heat ratio and for all practical purposes can be assumed to be 1.0. Cs is a correction factor which corrects the flow

. coefficient (Cv) for gaseous flow. Valtek Incorporated uses the valve sizing equation based on ANSI /ISA standarti S75.01, which does not use the factor C .

Werefore values of Ci are not available for the valve. However, typical values of Ci for a similar valve con be found in Fisher Catalogue 10, October 1984, page 1-15. For valves 18-inch and larger, size does not have a large effect on the value C,. S e values for C are listed in Table 1 of this report.

DYNAMIC ltElUE TESTS Tests were performed.to determine the torque coefficient E . He results are shown in Figure 3 and Table 1, where dynamic torque divided by pressure drop, rather than K , is shown, Frictional torque has been elim-insted in the prMnw (see Discussion of Dynamic Torque Tests).

Ts/oP = E Ds (Test with incompressible flow) (3) 1 In all cases, the dynamic torque tends to close the valve.

Equation (2) becomes Ts ' =(L D8 ) (C )8 sin 8 9 Pi (4) i (59.64)8 where & D8 'is given by equation (3)

! Values' of the squared terms are given in Table 1.

S e valve specification requires the actuator to be able to close the valve with a 2-to-1 torque margin at pressure drops of 48.4, 24.2 and 0 paid.

With no pressure drop (0 paid) there will be no flow and no dynamic torque.

Asstating that the downstream pressure in the other 2 cases is 14.7 psia, the dynmaic torque must be predicted at 63.1 and 38.9 psia upstream (P ).

Table 1 lista values of dynamic torque (which tends to close the valve) less frictional torque (which resists closing) for 24.2 and 48.4 pcid pres-sure drop. Se torque values listed for 0 paid are simply zero dynamic Page 7 of lo

l torque less frictional torqua. % ese torque values are also shown in Figure

4. A negative value indicates that the dynrunic torque tending to close the valve is less than the frictional torque which resista closing, so the~

actuator torque must exceed the negative value by a 2-to-1 margin. %e required actuator torque hamad on dynamic and frictional torque is listed in Table 1.

DISCUSSION OF DYNAMIC 'IERQUE TESTS h dynamic torque testa presented two problems. First, the water flow rate available for test was limited, so the pressure drop that could be

, developed across the valve was limited. h dynamic torque exerted on the valve disk was therefore limited. Second, the pressure fluctuations at the pressure tape, due to turbulent flow, were large enough that the small pressure drop through the valve could not be accurately deterimined with a manometer. A thirti problem was that during the test the valve disk position would change slightly because the valve does not have a positioner. %ese problems were solved by using the procedure explained below to calculate the change of dynamic torque due to change of pressure drop.

% e valve was installed as shown in Figure 5. Se valve downstream of the test valve was used to change the pressure drop through the test valve..

h flow meter was used to measure flow rate, which uns later used to calculate pressure drop.

, (Q (gpa))8 j aP = (5)

(Cv)2 Values of Ov were taken from Valtek Engineering Data 2, Rev 8/85 Section 16 Table 1. %e flow meter was calibrated in accortlance with 7altek proce-dures, and the calibration was checked after the torque tests were completed to verify the calibration had not been affected during the tests.

h procedure to take a measurement at a given disk position is as follows. First, with no flow through the valve, the actuator pressure was adjusted until the valve disk moved to the desired position and stopped. %e l disk position was recorded. % e downstream valve ~would then be opened. A

torque and flow measurement would be taken simitaneously and the disk l position would be recortled. h downstream valve would be opened further to l

produce a higher pressure drop through the test valve. A second torque and flow measurement would be taken and the disk position would be recortied.

h e pressure drop at each of the two flow conditions was calculated,

using equation (5). %e torque at each flow condition was taken as the

! average of the two readings taken at the flow condition, without subtracting j the null readings or correcting for friction.

I

%e factor T/oP was calculated by dividing the difference in the torque for the two flow conditions by the difference in pressure drop for the two flow conditions.

Page 8 of to

T - Tt ._

e T/aP = (T is average of two torque raariings (6) aPa-oP at a flow condition) h calculation eliminated the need to subtract the null torque rearling or frictional torque harmina the difference in torque for the two flow conditions was used, rather than the torque at one condition.

His prnrwhere was repeated approximately even 10 des _ from fully closed to fully opened and then back to fully closed.

As stated before, the disk position would change slightly during a test.

h is was due to the fact that with a constant pressure on the valve actuator the valve would move to a particular position with a residual torque opposing the motion left in the bearing-shaft. When water started to flow, the resulting vibrations would tend to ' jog' the valve shaft slightly further in the same direction as tha original motion. h average of the disk positions for the two flow conditions was used.

h re was considerable scatter in the data due to the small pressure drops and the resulting low torques. h data shown in Table 1 and Figure 3 envelop the lowest values from the tests. In all cases, the dynamic torque tends to close the valve. Because the valve is required to close during an accident, the use of the highest values of dynamic torque would result in smaller required actuator torque to close the valve. h refore, the use of the lowest dynamic torque is conservative in that it requires hisher actuator torque.

h question of highest or lowest dynamic torque is actually a moot point, because as shown in Table 1, the highest actuator torque is required when there is no flow through the valve to assist closing.

ACIUA'IOR 'IORQUE OUTPUT

%e actuator torque output test was perforined on the valve with no seat installed, and no flanges installed. h is was necessary in ortler to be able to lock the disk in position.

%e strain gage bridge was zeroed while the disk una stroking open. he null torque raading was established as -493 in-lbf.

he valve was opened and allowed to close, by the actuator spring only, against a wooden block set between the disk and body stop. A torque reading was taken. h n air pressure was applied to-the actuator, tending to close the valve. A torque raadinn was taken. his procedure was repeated at various disk positions.

The results of the test are shown in Table 2 and Figure 6. he torque values shown are corrected for the null torque reading. % e actuator torque at 70 psi actuator pressure was found by subtracting the torque due to the Page 9 of 20

. o spring from the torque due to spring-plus-air pressure and divided the result by the applied air gessure. H is value of T/ psi was then multiplied by 70 psi. h net torque to open the valve is the difference between the torque due to 70 poi pressure opening the valve and the spring torque closing the valve. h torques p M M with 70 psi actuator pressure are shown for comparison with the theoretical values shown in Appendix A of this report.

VALVE AND ACIUA10R m*=

h e Operability Pre-Analysis Report (Appendix A of this report) explains the =len1= tion of atresses and allowable stresses. N =len1=ted stresses in the Operability Pre-Analysis Report were all based on a maximum torque of 7361 in-lbf (seating), and a ratio of allowable to calculated stress of 2 to 1 or more is shown.

h Operability Tests showed that the maxista torque actually is 4403 in-lbf. h erefore, the analysis in Appendix A is conservative. Stresses and stress ratios which are calculated h==ari on 7351 in-lbf torque should be adjusted to correspond to 4403 in-lbf. h corrected values are shown in Table 3 of this report. Calculations are shown in Appendix B.

l Operchility Pre-Analysis FURPOSE ,

- N purpose of the operability analysis is to demonstrate by 'a oombination of analysis and testing th~at the referomoed valve and actuator  !

meet the following requirements.

1. h available setuator torque must be twice that required at all angles of disk opening when considering valve differential pressures of 48.4, 24.2, and 0 psi.

2. The actuator torque produced by the satsator spring alone must be i

twies that required to elose and seat the valve with no flow assist.

3. Valve and setuator stresses eritical to operability must have a ratio of allowable to natual stress ogsal to or greater than tso.

Stresses will be calesisted based on the worst case torques / loads.

PROCEDURE N operability pre-analysis will isolsde only the theoretical torgne analysis for requirement number 2 above and sa analysis of valve and metaator stresses for requirements asaber 3 above.

Operability tests which will verify the torque requirements of the valve and the torque capability of the motsator will be isoladed in the final operability smalysis report. See Appendia A for a brief description of the operability tests that will be performed.

The detailed stress analysis and/or statio defloation operability test

~

required to gsalify the valve and actuator will be isolsded in the valve Design Report and/or Qualifloation Test Report but will be referessed in the final operability report. The final operability report will address all operability questions in Requisition 4409/8409 Rev 15 and in the April 18, 1986 meeting.

h operability pre-analysis is based on the design which is detailed in'the valve Assembly Drawing A34753/3-48 Rev 1 and the valve Bill of Material V34753/2-48 Rev 1.-

TORQUE REQUIREMENT I -

ne torque required to close and seat the valve with no flow assist is

{ simply the torque required to overcome bearing sad seat friction. It osa be i

estimated by the following formula, which was.eapirically developed from aumerous tests by Valtok on various sizes of valves.

l T, = 27(Dd I*

i where T, is disk seating torque with no flow assist (f a-1bf)

Dd is disk disaster (la).

Pye A-2 l

l L_. - - - - - - - - - - ~ - - ~

T, = 27(16.5) * = ~ 7351 ia-1bf Note that this torgue oseurs at the fully closed disk position.

m valves will be installed so that flow from 'the oostainment vessel will as.sist the seating.of the disk and will more tham.eospensate for the additional frietion eassed by the pressure drop through the valve. It is assumed that the dynamis torque on the valve disk due to flow through the valve is less than the disk seating torque. This assumptio's will be verified by the operability tests whiek will be eondmoted later (see Appendix A).

m required torque at which the sotuator torgue (spring only) sad stresses' will be analysed is therefore 7351 in-lbf. This value will be verified by test (see Appendix A).

TERORETICAL ACTUATDE M M N theoretical torgue output of the valve setustor with 70 psi pressure applied to the actuator is listed in Table 1. These values were calculated ignoring frietional losses.

m first solana of Table 1 lists the torgue due to 70 psi actuator pressure only.

m second oolana of Table 1 lists the torque due to the actuator spring only. The third solema is the met torgue available to opes the valve. hee three sets of torgue values are plotted la Figures 1-3.

Table 1 shows that the sotsator spring will supply 20443 in-ibf of torque at the closed position, which is greater than twice the required seating torque.

(2)(7351) = 14702 20443 > 14702 -

J,& H Atg ACTUAIDE STRESSES .

The stresses in valve and sotuator composeats which are critical to valve operability we're smalyzed. Other ocoponents which are not critical to valve operability were not analyzed.

m aseeptsase criteria is that the stress must have a ratio of allow-able stress to notaal (calculated) stress ogsal to or greater than two.

Nome of the composeats which were analyzed are classified as pressure retalning and acas of the materials for these components are ASME code-controlled. In addition, all of these components, with the exception of the valve shaft, are external to the pressure boundary and are not subject to the harsh environment (323*F). The valve shaf t is exposed to the harsh

' environment for the short duration of the elevated temperature. The rules for dete,rmining allowable stresses given la ASME Sec III NB-3546.3(a) apply P% e. A- 4

.._= _- . . _ . - - - - . - - . - _ - -_ __ . .- _ . . _.

, specifically to tho volva sh,ft. Be 3ts3 no rules are gives for determining the allowable stresses for the other sosponents, 'the same rules given la NB-3546.3(a) will be used.

m rules in ND-3546J(a) state that the allowable (tensile) stress is the lesser of two-thirds'of the minimum specified yield strength or one-fourth of the minissa specified tessile strength. . N allowable stress in shear will be takes as 58% of the allowable tessile stress in scoordance with the eaziana distortion energy failure theory.

I m a ma Coun m 0NS h valve actsstor is designed so that the actuator limit stops absorb

the portion of' the trust of the pistos/ spring which eseeeds the thrust that is required in order to produce the assessary torque at the valve shaf t.

The valve shaf t and setuator linkage seaposeats are subject only to the forces and torques aseded to prodsee the required torque at the valve shaf t.

' Based on the assumption that the nazimaa torgue oeeses as the valve (isk oloses against the seat (or breaks out of the seat) and based on the fact i

that side loads are greatest at that same position, the valve shaf t and linkage components will be analysed at the seating torque (7351 in-1bf).

h pistos stem and spring stem will be analysed at the worst combination of pistos thrust and side load.

Operability Qualification of purse and Vent Valves - Attehment 1 1A. Dynamic torque coefficient test results shown in Figure 1 and Table

1. h e test setup is shown in Figure l

1B. Operability Demonstration is by a combinat on of analysis and bench testing. See Demonstration, page C-2 of this report.

1C. Stress analysis of the valve and actuator, to show operability, is shown in Table 3 and Appendix B of this report.

1D. Seismic analysis and testing will be included in the valve Design Report which will be issued at a later date. Note that the environmental qualification test of the valve seat includes a static operability test which, while not intended specifically to riaernstrate operability or the valve, does demonstrate the integrity of the seat- disk seal under seismic loads. A dynamic test was performed to qualify the valve actuator and % trate operability during a seismic event. RI 1E. Refer to assembly drawings A34753-49 and A34752-48 for

1. Flow direction - nomal purge and accident

2. Disk closure direction is clockwise viewed from the actuator end of the valve shaft.

3. Curved side of disk is away from containment

5. he valve was originally intended to be installed with the shaft vertical, actuator up. Operability testing was perfomed with the valve oriented that way. See c e t A2 under Attachment 2. he R1 valves were later installed with the shaft horizontal, spring case up.

4,6. Orientation of pipe and other valves is not considered here per instructions from Bechtel Energy Corporation. ~

1F.  % e torque tests reported in this report demonstrate that the actuator pr~h m sufficient torque to operate the valve. See Figure 7.

2. Specific valve type questions are not applicable, per Bechtel Energy Corporation.

3. he torque coefficients were detemined by test. Piping did not simulate field installation. However, the ratio of actuator torque to required torque is sufficient to overcome twice the dynamic torque even in the event that piping effects cause the dynamic torque to reverse direction.

Operability l

%e operability tests showed that the valve actuator torque capability is at l least two times the required torque to overcome valve friction. Se worst case valve torque requirements is with the valve closed. See Discussion of Dynamic Torque Tests page 7.

1. Valve closure rate is asstamed to be linear. However, no credit for pressure buildup to assist valve closure is taken so the closure rate is not important to the operability analysis.

2. In accidental conditions, flow is toward the shaft side of the disk and tends to close the valve. However, no credit is taken for this dynamic torque when calculating the worst case torque requirements.

3,4,5,6. Not applicable per Bechtel Energy Corporation.

7. See <wn-nt 3 to Atteh-nt I above.

8. Not applicable here.

Demonstration Operability has been demonstrated by a combination of analysis and bench testing as reported in this report.

'lhe stress analysis contained in this report shows that the components critical to operability have a stress margin of at least 2 to 1. Seisedc loading has negligible effect on the components analyzed in this report in Appendix B. See also cam-nt ID on page C-1.

Sealing integrity of the valve seat-disk is ensured by the environmental qualification test performed on the valve seat. H is test includes thermal

, aging, mechanical aging, irradiation, and LOCA simulation with chemical spray. %e environmental qualification test is being perforsned on a valve of identical size and construction as the production valves. %e results of this test will be reported later.

Bench Testing A1. All tests reported in this operability repart have been perforined on a production valve or on a valve of identi::ai size and construction as the production valves.

pcge C3 of Cq

w - .

A2. With the exception of the actuator torque output test and seating torque test, all tests were conducted with the valve oriented with shaft vertical, actuator up. h valves were later installed with shaft g horizontal, spring case up. Piping during the testa did not simulate field installation. See comment 3 on page C-1.

A3. he following factors 'have been included in the operability tests and -

analysis.

a) IACA similation (internal components only) b) Seismic l<=dina will be considered in the valve Design Report as stated in Cr== ant ID on page C-1.

c) Temperatum soak d) Radiation exposure (internal components only)

Chemical exposure (as part of the I4CA similation) e)

f) Debris could affect operability in two ways. First, in a gross sense, large objects left in the pipe line could prevent the disk from closing. Obviously, construction tools and materials, etc.,

cannot be left in the pipe line. Second, small debris such as pipe scale or weld slag left in the pipe line could <iamare the disk and/or seat or become lodged between the disk and seat, which would affect the ability of the valve to shut off tightly. Pipe scale did cause a sealing problem during the IDCA simulation of the i

environmental qualification test of the seat (as will be reported in the Qualification Test Report to be issued at a later date).

he pipe scale in the test came from the boiler and ILCA chamber used to perfom the IDCA simulation. During the IDCA simulation the valve outlet consisted of a 1/2-inch pipe. h e velocity of steam through the valve was very low and allowed the pipe scale to e-late in the bottom of the valve. In the field, the valve will be installed in a galvanized pipe system which will prevent the fomation of pipe scale . The pipeline must be properly cleaned before the valve is installed.

In-situ testing is not applicable.

3.

Analysis if used, should be supported by tests which establish torque

. coefficients of the valve at various angles. As torque coefficients closure flow direction and approach flow, these things should accurately represented during tests.

Specifically, piping installation (upstream and downstreans of the valve) during the test should be repre s sentative of actual field installations. For example non synetric approach flow from an elbow upstream of a valve can re,sult in fluid dynamic torques of double the magnitude of those found for a valve with straight piping upstream and downstream. l

4. In-situ tests, when performed

~ performed on a valve of each si a representative valve, should be represent the' worst case load. e/ type which is determined to should be considered. orst' case flow direction, for exar.ple, For two valves in series where the second valve is a butterfly valve, the effect of non.symetric flow from the first valve should be considered if the valves are within 15 pipe diameters of each other.
