SUMMARY

, t 1
a 4 I Due to the design of the Posi-Seal butterfly valve with the
~
i disc being asyssetrical, flow in the preferred direction tends to close the valve. .In the nonproferred direction the disc tends to stay in the open position until it reaches an i
, angle of approximately 75 degrees open, then tends to close.
See Figure 1 on Page 2 for an illustration of what direction is preferred. For the subject valves those inside containment are in the r nonpreferred direction and those outside containment are in lj the preferred direction. *
~[ If a LOCA does occur the scenario given below describes what
_f effect the large flows resulting from the LOCA will have on the subject valves. 1
.A. If all the subject valves are fully open.
l '*:
,, Under normal flow conditions the subject valves would pass 25,000 SCFM with an approximate pressure drop of
- ,-J' 36 in. water.
- i 7 If a LOCA were to occur the initial flow due to a LOCA l will create an aerodynamic torque of such a magnitude l
! that the valves inside containment will remain open possibly causing damage to the actuator.
!.3 i. i l! b
- For the valves outside containment the aerodynamic
! torque will override the actuators and cause the valves i'[l to partially close and damage the valve disc pins. Upon j U receiving the signal to close, the valves outside i g containment will close, however, due to the damage to L m the dise pins a tight shut off will not be obtained. 4 L (? -

a . ., isolation valves can withstand a loss of coolant accident (LOCA) as well as a' seismic event of magnitude as given in customer's specification and still'
,, mair.cain operability.
i .,

~~
The escape of containment staosphere during a LOCA will result in
.; p- ' aerodynamic torques acting on the valve assembly if it is in the open
!j position. These torques are a result of the disc acting like an airfoil wanting to rotate about the axis of the stem. This analysis will determine q the magnitude of.the aerodynamic torque and its effect on the operation of the valve assembly. Also taken into consideration is the effect of 1
building atmospheric pressure on the actuators. t The seismic aspect of the analysis will consist of determining the . natural frequencies and stresses of the valve assembly, assuming the basic valve body'to be rigid and the actuator to act as a lumped mass q : [j concentrated at its C.G. and rigidly connected to the valve bracket through the bracket bolting.
'.*7 l
I Those critical sections of the valve assembly such as the bolting.. {l U neck, staa and pin are analyzed assuming a g static load (magnitude per j customer specification) applied at either actuator or disc C.C., in
- r
-; 1 each of the orthogonal directions simultaneously. Seismic stresses are - .] ' L! combined with operating stresses as well as the stresses-due to the LOCA
[ aerodynamic torque. Section modulus of the valve body and deflection of the actuator n relative to the valve due to sairaic loading are also analysed. L

RECOMMENDATIONS AND CONCLUSTONS
?
Based on the results of the analysis Posi-Seal recommenda that the amount of valve opening for all the subject valves
~
be restricted to 65 degrees. .This can be accomplished by bolting a stop to the internals of the -Matryx piston cartridge which would limit the stroke of the actuator. See Figure 2 on Page 8. y
, To insure that the valves are not overstressed during a
~-
~
combined LOCA and seismic event, it is recommended that tra bolt material for valve A07123 be changed to A354GRBD. 1, It is concluded that 1"f the amount of valve opening is 1 restricted to 65 degrees and the change in bolt material l_ - ande as recommended above, the subject valves will properly i! operate within the required time during a combined LOCA and seismic event. Whether the amount of pressure drop across the valves under normal flow conditions is acceptable with l the amount of valve opening restricted to 65 degrees remains
-. . for Stone & Mobster to determine.
>q The ability of the Tetzel seals to provide a proper shut off
, .' is based on the following:
., 1. Posi-Seal's experience with Tefsel seals in applications
+
where the velocities are comparable to those the. subject L. valves will experience during a LOCA.
- 2. Radiation testing performed by DuPont as reported in d[1 Reference (b). For Posi-Seal's application we have rated the Tefsel seals to 3 I 10 rada.

LOCA ANALYSIS The purpose of this analysic is to determine what effects the aero-
~
dynamic torque resulting f:cm a LOCA vill have on a valve assembly. Since s 7 aerodynamic torque is, dependent upon the flow conditions and the valve
. angle. computer programs are developed which: I
- 1. Models the piping system
- 2. Dete:r.ines the flow at various valve angles 3 Simulates the actuator as it strokes the valve from fully open to fully close a
p , Modeling the Piring System
.For the subject order there are two piping systens which are to be investigat ed. They are:
.. Case 1 A Valve A0V123 closes, Valve A0V165 remains open
, B Valve ADV165 closes Valve A0V123 remains open Il Case 2 A Valve A0V128 c3oses, Valve ADV166 remains open -

These factors are inputted into the computer program either as a K value, as a length of pipe, a change in pipe diameter, or i u as a valve C7.

',-- The torque equations are formulated into the computer program F- I
" FLOW-C '.- This program calculates the various torques acting on the valve and the amount of valve closure as time is incremented until

"~
dMaic torque for angles other than the ten degree increments i 7' calculated by " FLOW-GAS" the values for the densities, pressure drops U and velocities are taken from " FLOW-GAS". interpolated to correspond to the angle of interest and then the aerodynamic torques are calculated based on those values. The reason for calculating aero-i dynamic torque in this manner is that density, pressure drop and [ velocity are more linear between the ten degree increments than is the aerodynamic torque. A i

- - A 7 Per Reference ( d )' when a Loss of Coolant Accident (LOCA)
L, occurs the pressure inside containment will increase to 9 psig and the temperature to 185 degrees F. For the , , auxillary building the pressure will go up to 3 5 psig and E
-the temperature to 160 degrees F.
i
~
To perform the LOCA analysis it is assumed that the LOCA t, occurs inside containment and the pressure inside ~the auxillary building is atmospheric. Consequently _ the q pressure drop across the piping systems containing the l : Posi-Seal isolation cobtainment valves is 9 psig. This assumption is made for conservatism since the larger the
,c pressure drop, the larger the flow; consequently the larger
[ I the aerodynamic torques acting on the valve. l l "1 Since the make up of the media is not known, it is first l ' ~ l assumed to be steam with its density based on a saturated pressure of 9 psig. Then the analysis is performed assuming
~q. the media as air. When the media is steam it will be
'; referred to as Condition 1 and when it is air it will be i considered Condition 2.
l
~
The torques resulting from a LOCA based on the above j conditions and assumptions were determined using the prograa
' FLOW-GAS *. The computer results can be seen in Appendix B q on the pages as described below:

( ~i !^ 1 a 7- For.the valves inside containment (A07123 & 128) the torques
- resulting-from the LOCA at 90 degrees exceed the maximum allowable torque of their 33122-SR80 actuator. This maximum
-. allowable torque is 66,800 in.lbs. Consequently the amount of valve opening has to be restricted. Since the flow with j the valve in the .nonproferred direction, as are the valves
^'
inside containment, causes a torque reversal of . approximately 75 degrees, Posi-Seal recommends that the _; amount of valve opening be restricted to 65 degrees. m 1 With the aucunt of valve opening restricted, the pressure
~
drop across the valves under normal flow conditions will be greater than with the valves fully open. The amount of
, pressure drop to 65 degrees open and 90 degrees open is J determined on Pages B-33 and B-34, respectively.
1 . n:
~
For the ' valves outside containment the torques resulting from the LOCA at 80 degrees will cadse the valve disc pins 2 to be over stressed when combined with the loeds resulting from a seismic event. See Page E-9 of Appendix E. Since 1 u the calculated LOCA torques do not take into consideration the . effects of the flow coming from the valves inside containment, it is recommended that the amount 'of valve opening be restricted to 65 degrees. Not only will this add conservatism to the amount of torque resulting from the LOCA i r, but will be consistent with the valves inside containment. I : . Shown in Appendix C are the calculated closing times with
- the valves fully open and with the valve openings restricted
, "I to 65 degrees. These closing times were determined using
- a. the computer prograa ' FLOW-CL*. Shown in Appendix D is a

l THE' INFLUENCE OF A BEND
~T l
._J j -
As can be seen in Appendix A just upstream from valve A0Y123 i is a bend. The purpose of this section is to. determine the effect of this bend on the aerodynamic torques valve A0Y123 will be subject to during a LOCA. ( Posi-Seal has performed an investigation to determine what r effect a pipe bend will have. To date this investigation has not revealed anything Posi-Seal can use with confidence. Consequently, Posi-Seal has taken the following approach: 1 1. Assume the flow results in a resultant' load acting at
- u. the midpoint between the edge of the-disc and the stem centerline.
;D
] 2. Determine the load based on the principles of impulse and momentum.
3 Calculate the resulting torque choosing the angle of attack which results in the largest to'rque when added to a the aerodynamic torque of the normal flow thru the p valve. ~ d ! , The assumptio n tha't the flow resultant acts at the midpoint l between the edge of the disc and the stem center line with a l " tee upstream is as follows:
, C 1. For flow through a straight pipe the largest aerodynamic l
b torque will occur at 80 degrees open. This torque is predominately due to the lift and drag forces acting on m the disc. Only a small amount of torque is due to the flow impacting on the disc since the soment are is
" relatively small.
g I!d[l 2. In determining the aerodynamic torque as a result of having a bend upstrema of the valve for the case where
; the torque due to flow impacting the disc outboard of
'; the stem is added to that due to the lift and drag _
j forces, the latter torque will be sasumed to be that at 80 degrees. This assumption is conservative since the _ flow angle of attack will be less than 80 degrees. a

. .4 3 It is assumed that the. resultant of the flow impacts the disc at the midpoint between the dise edge and the stem
" center line throughout_the closure from 90 degrees open to fully closed. Although this may not be conservative
[ at the smaller angles, it will result in very
- conservative results at 80 degrees where the maximum torques due to the lift and drag forces occur. See the diagram below.

, Based upon the flow te. sting performed'at Posi-Seal, the following
}. . general . observations concerning Hydrodynamic Torque of Trunnion Valves [))
~
'ca'n be ma'de:L _
(1) ~ For preferred flow, 'the Hydrodynamic Torque will always . x n want to close the valve.~ See Fiour~e 3.
~
~
LM . (2)_ Fof non-preferred flow, the Hy'drodynamic Torque will, through' b '
. 70* to 80.* of valve rotation (the exact location varies with valve ' class), want to close the : valve. Beyond this point,- the 1
- [- "
Hydrodynamic Torque will want to open the valve. See Figure 4.. o . 1 f N.7% (3) Except for the 90*: valve location where the Hydrodynamic Torque . +E~ , factors are of equal magnitude.fer both preferred' and non-pre - _. ferred. flow but of opposite sign, the non-preferred. Hydrodynamic 9 Torque factors are considerably less in magnitude than thos,e d.! *
.- for preferred flow. See- Figures 3 and 4.
t':
~
M- ~ (4): _ All of the Hydrodynamic Torque factors (for both preferred and non-preferred flow)-decrease ~ with increase in valve class. ex: Qd . ~ _ ,1 Hydrodynamic Torque factors for a. 600 lb. valv'e are.significantly
. -less than those for a 150 lb. valvec . See Figures 3 and 4.
~
(5) The Hydrodynamic Torque factors increase approximately proportional-
-N lJ
.. on alve c as
. The total Trunnion Valve. Torque at seine angular position (other than -
L opening or closing) is in actuality a sumation of three separate torques,
- k -
. .s stsn packing torque, bearing friction torque and the Hydrodynamic Torque 71.-
~
discussed above. Except for.small size valves (6" and less), the stem y' . . packing torgue is a -smai1' percentage of the total valve torque. For large J- .' sized valves, above approximately. 45*, the Hydrodynamic Torq'ue is the major d- -
,V component of the total valve torg'ue, below 45' bearing friction torque be-comes the major contributor. All three components must be considered inorder cO b' : to' accurately evaluate a valve's performance. >
r Inordek to better understand the reason for Hydrodynamic Torque occuring, k one must visualize. the valve's disc ,as an airfoil. The Hydrodynamic Torque c . Epi generated at some angle is a com' osite of fluid flow lift and drag forces
