Purpose:
I
! This calculation evaluates the capatality of susceptable MOVs to overconne pressure locking conditions in i order to ensure they can perform their safety functions. It was prepared to document the operability of
- these MOVs in response to NRC Generic I4tter 95-07, which roquares that such an operability 4
deter =n==tian be made within 90 days ofiemance of the genenc letter. This calculation is not intended to I be a Anal prorrs===*ie resolution to Generic IAtter 95 07 concerns at CCNPP, but rather deananstrates l that the susceptible MOVs are operable in their current status.
, 'f*ans review is not intenderi to be a veri &=sian of which MOVs are ==rapeihte to pressure locking ,
- Rather, it is an independent check of the application of the calcutatmn's mathadalogy to valves selected by l
- the MOV Prcsect and Plant hi-ing. Attachment I gives the MOV Project's analysis of power 1 operated gate valves at CCNPP and winch valves they have daamad to be susceptible to pressure locking.
l 'niis review is not intended to be an indarendent verification of this MOV Prcsect effort.
- . Methedalogy
i l Calculation of valve seat reaction forces due to bonnet pressure loads was performed using standard j relationslups from Roark and Young's "Fonnulas for Stress and Strain." Since the standard formula in
- Roark that best approximates the valve disc geometry does not include the effect of pressure on the hub l
j area, a fbroe based on the valve differential pressure and hub area was added to the force predicted by j Roark. The unwedging force was also calculated using standard static relationships between seating and i namentmg forces and resultant frictional forces based on wedge geometry. All of these computatnons, I i which make up the " standard evaluation" portion of this calculation are based on r~a==i=d engineenng
! practice 'ntis methodology is in use for this application at other nuclear power plants and is outlined in i NUREG/CP-0146.
I i
4 l General Cossanents:
[ Since this calenlasian was prepared as an assessment of the operability of MOVs susceptible to pressure i locking, it is based upon the current "as left" conditions of these MOVs. Saaribally, the maximum
- closing thrusts used to form the basis for the calculation of unwedging forces are based upon data 1
determined in the most recent j h e.2 of MOV static VOTES testing. Therefore, this evaluation only remains valid as long as test data (including the ofrecss of t=g - ek inaccuractes) indicates
. msxunum thrusts at or below the values in this calculation. Should future testing indicate higher seating
- thrusts, operability of that MOV will have to be re-==ana4 Consideration should be made to establishing j a maximum allowed value for seating thrust based on pressure locking concerns Establishing this upper bound would reduce the potential for having to revise this calculation if future testing indicated thrust i values above the current "as left" conditions.
i i 2-MOV 651 and 1/2-MOV452 require force appranching the manafLa's one time limit for the valve stem. Since the continuous duty rating is eveeaded, operation of these valves under a pressure lock j scenario will require evaluation of the valves' capability for future operations. This calculation only darn =wnts operability of the valves in their current status. If these valves are over operated up to the one-l time rating in order to overcome pressure locking, additional evaluation will be required.
l' Two of the valves addressed by this calculation should be reconsidered for =- Wility to pressure locking. 1/2-MOV-2080 are the instrument air containment isolation valves. These valve are in air versus water service, so the standard pressure locking ecmaarao due to water trapped in the valve bonnet does not apply. Even if the valve bonnets were air tight, such that air could become trapped, the effects l would not be as severe as in the case of a trapped liquid. In contrast to liquid, any air trapped in the valve 1

+
bonnet would be escreasible, providing much less resistance to the valve disc being moved by the valve actuator. Also, the rmsure increase in a trapped gas due a rise in temperature is less severe than for the j same quantity of trapped liquid. The air pressure rise would closely follow the ideal gas relationship for j pressure and : with constant volanse (P - Pi T: / T ),i rather than the 0.4 psi /T predicted for i liquid. For ~*P. the 507 temperature change for 1/2-MOV-2080 would cause pressure to rise from
- ~
100 psig to about 110 peig, rather than the 20 psig increase predicted by the test data for trapped water.
This calculation is conservative by treating these valves as susceptable to pressure locking and by j evatusting bonnet pressure increases as if water were trapped inside Although treatment of these valves
- by this calculation is conservative, their inclusion may not be necessary. The MOV Project may want to mn ider removing these valves from the scope of this concern as progress is made towards Saal resolution
- of the pressurelockingissue.

(I) PURPOSE
^
In response to Generic later 95 07 Pressure T dne and Thermal Biadia= of Sa_ fan-j Related Power-Opera *M Gata Valves. this calculaten was p fui.i.6d to i.r.cantam that 4
all valves deemed susceptible to pressure lockmg (See Attach- 1) are capable of l overco..q the mammum pressure locking condition for each valve.
1 a I I
I (II) RESULTS r
4 All valves within the scope of this evaluation have been shown to be capable of operatmg i
under the maximum pressure locking cceditions, that is with maximum pressure withm the i bonnets of the valves. The valves have been shown to have sufEcient capacity directly by l
! analysis or by reducing some inherent conservatism. 1/2-MOV-651 and 1/2-MOV-652
{ were evaluated to show sufHcient capacity based upon allowables for the valve materials.

i (1) Maximum nrust values are rounded DOWN to the nearest Ib.
Justification: Conservative 1
j (2) Muumum nrust values are rounded UP to the nearest Ib.

1 (3) ne VALVE DISC TO SEAT FRICTION FACTOR is 0.40.
J# =4-1 A disc-to-seat friction factor that is based upon Stellite to Stellite contact per Reference 49. His coefHeient of friction conservatively assumes non-lubrication. Note - Velan design 4hdan, BGE i D=- No. M-91-044 (Ri,few 12) uses a friction factor of i
0.25. 0.40, used in this calculation, is mere conservative.
- (4) POISSON'S RATIO is 0.30.
4 I
Justification The ratio of the lateral stram to the axial strain that is typically taken 3 as 0.3 for steel (Reference 11). Note - Velan design calculation, 9
BGE Dx- --=4 No. M-91-044 (Reference 12) uses a Poisson Ration of 0.27 for these valves. 0.3, used in this calculation, is more
{ conservative.
1 (5) He assumed BONNET PRESSURE is the maximum pressure that the valve will be
- subject to under design basis con &tions.
1 Justificatierr %e assumption in a pressure lockmg scenano is that the pressure in j the bonnet is that maximum pressure of the fluid on one side of the disc. That pressure flows into the bonnet since the pressure pushes
- the flexible disc to scat on the opposite side valve seat. When the
! pressure side of the valve disc depressunzes, the flexible disc will
)
seat on both seats, trapping the maximum pressure in the bonnet of the valve. %c force exerted by the pressure in the bonnet is the i equivalent force on the disc and therefore, the disc on the seat. This i is an ad&tional force that the valve must overcome to open. The followmg is a list of the assumed pressures for each valve.
4
! 1/2-MOV-504 - Per the applicabic pressure calculation (Reference 20), the maximum pressure
- these valves will be subject to is 35 psig. De valycs are located in the auxiliary building, in space
- A218. Per Reference 43, this space is subject to a maximum temperature during a LOCA of j 121*F. Based on an ambient temperature of 80'F, the temperature rise in the area may be as Idgh as 41*F. Based upon the results of Reference 21, this could result in an increase to the pressure in 4
Page 9 of 36 11/20/95 1
CA00831 Revision 0 the bonnet of 16.4 psig. This results in a total bonnet pressure of 51.4 psig. The pressures on the inlet and outlet sides of the valve would be O psig.
1/2-MOV-514 'Ihe maxunum line pressure that this valve would ever exponence is 113.6 psig 2
(257 A of head
- 62.4 lb/ft* *l.02
- 1/144 A f;,2) which is the dead head value of the pump (Reference 44). In =M% there is heat tracing that is present that causes L..y wore swmgs of between 140 and 160 'F. A 20 'F rise in Loy-Mare could result in a 5 psig pressure rise. This is based upon testag p Two.4 by Northeast Utahtnes (Reference 21). This results in an assumed bonnet pressure of 118.6 psig. Conservatively, the valve is mammarl to open without the Boric Acid Pump started, so both inlet and outlet pressures are 0.
1/2-MOV-651 & 652 - Per the applicable pressure +d=+inae (Rd .se 13,14 and 15), the maxmmm preasure that these valves are subjected to is Reactor Coolant Pressure of 2250 psig.
The inlet side of the 1/2-MOV-651 is subjected to a mammum pressure of 256 psig. The inlet side of 1/2-MOV-652 is subjected to a maximum pressure of 253 psig.
1/2-MOV-20M - The maximum pressures that these valves are subject to is the discharge pressure of the compressors,100 psig. The normal Lup ;rEure will range from 80 'F to 130 'F during an accident scenano (Reference 43). Per the Northeast Utility testms performed to determine pressure rise in a valve bonnet per i gm. hare rise (RJ--s 21), the rate was deteratined to be 0.4 psig rise per degree Fahrenheit. Applying this to the 50 'F change in i ..e-eure during an ac++ ,
the total pressure in the bonnet may be as high as 120 psig for these valves.
1/2-MOV-4144 & 4145 - Per the applicabic pressure 4da*1aa (RJmos 16), the maximum pressure these valves will be subject to is maximum contamment pressure,50 psig. Due to elevation differences, the valve can experience 57 psig. The pressure calculatina also states that the valves open 36 minutes after Reactor Coolant Pipe Rupture. At that poet, the i-uyviMure in the sump is 240 'F (RJwus 48). Conservatively assuming that this t.;+inare will be transferred to the bonnet, the bonnet 6-y-Mure could rise 160 'F (240 'F minus valve location ambient i gw4ure,of 80 'F). Per the Northeast Utilities testag report (Reference 21), the pressure in the bonnet could rise 64 psig. Therefbre, pressure in the bonnet is assumed to bc 121 psig. In addition, at that time, contammaar pressure has da.;i.e.54 to between 8 to 15 psig.
Addmg for pressure caused by differences in elevation results in pressures between 15 and 22 psig on the inlet disc of the valve. For conservatism, the lower pressure,15 psig, is =="ned to be the pressure at the inlet side of the valve. Per Reference 16, the outlet side of the valve would be at 0 psig.
1/2-MOV-4516 & 4517 - Per the applicable pressure calculation (Reference 47), the maximum pressure these valves will be subject to is maximum discharge pressure of the feed pumps. I 165 ,
psig. 'lhe inlet pressurc would be the shutoffhead of the condam* pumps, approximately 275 psig. The outlet side of the valve would be at 0 psig.
1/2-MOV-6900 & 6901 - Per the applicable pressure calculation (RJmus 18), the rr.4xanum pressure that these valves would see is 50 psig, maxiinum containment pressure. In addition, the temperature in containment at the time the 6900 and 6901 are required to open (9.55 days per i Reference 48, Section 14.21) would be approximately 135 *F (Reference 48, Section 14.20). This is assumed to be 55 'F above normal contamn'ent temperature. Per Reference 21, this would i
constitute a pressure rise in the bonnet of 22 psig. Therefore, the pressure that is assumed to be Page 10 of 36 11/20/95 l
I
' CA00831 Revision 0 locked in the bonnet is 72 psig. Note - 1/2-MOV-6901 are located in the cast piping penetration room which has a lower tanperature than contai , but 135 'F will be conserveively applied to i
1/2 MOV 6901, as well. Per the pressure calculation, based on the time requirc.nent for these valves to open, the maximum pressure on the inlet side of the valves by the tiny; the valve is 4
required to open would be 6 psig. Therefore, 72 psig is assumed to be the pres sure in the bonnet l
4 and 0 psig is conservatively -mad to be the pressure on both sides of the valve disc.
i l (6) MAXIMUM CLOSING THRUSTS are the boimdmg values.

(VI) DISCUSSION / METHOD OF ANALYSIS 1
1 To &&m-e whether or not there is sufBeient margm in the design of the subject Motor l j
Operated Valves (MOVs) to open under pressure lockmg conditions, the following forces l 4
are calculated; i Reaction fort: due to the bonnet pressure loads on both the downstream and j i.p.hw sides of the disc.
The maxunum additional seat reaction force due to the differential pressure
- loadmg on the hub l
W The unwedgmg thrust required to open a closed valve Once these forces are c=W1= tad they are added together to obtam the muumum thrust
} 1 needed to open the valves under pressure locking conditions. The internal pressure for '
j cach valve will be analyzed using analysis from Reference 22. This analysis will provide the force exerted on the seat ring by the disc with the internal pressure. The analysis for this calculation was performed using an EXCEL Spraad= hear J,
l Once the total force required to overcome the potential pressure locking force is calculated, i it will be compared to the M=vi= = Control Switch Trip (CSTwax) value which was i developed in the applicabic thrust calculation for cach valve. This comparison will show whether there is sufEcient thrust margm available to open the valves umler pressure
- lockmg cosubtions. CSTuax is defined as the maxunum force allowed during the strokmg j of the valve. It is based upon component allowables or capabilities.
1 This calculation is performed in three steps. In the first step, the standard evaluation, the l
} calculation results may indicate that the MOV does not have the maram to overcome the l
pressurc locking scenario. It should be noted that when calculating CSTuAx. the thrust
! calculations are extremely conservative in the interest of ==vi=% MOV reliability.
i 4
' If the initial evaluation does not riamanstrate margin, an ' - "=a evaluation will be performed erther raalad=: stamiard inputs and generic assumptions with MOV specific data. Also some conservatism can bejustifiably removed based on actual MOV performance.
1 Lastly, if the MOV is still shown to be ia d~== after completion of the intermediate evaluation, an engmeenng evaluation will be performed. The objective of this evaluation is to assess the operability of the specific MOVs.

, needed to overcome pressure 'xkmg for both 1-MOV-2080 (4685 lbs) and 2-3 MOV-2080 (3968 lbs). ) Conclusion - MOVs have sufficient capability to overcomo pressure LWa= l 1 1/2-MOV-4144 =ad 1/2-MOV-4145 1 l Limit controlled MOVs, such as 1/2-MOV-4144 and 1/2-MOV-4145, control the l MOV by opening a contact in the control circuit after a specified number of turns of i the limit switch gean, (marked C8 on the VOTES trace). The torque switch is in series with the limit switch contact which provides backup protection for the operator if a higher load is exper==d prior to limit switch trip. In contrast, a ! torque controlled MOV opens only on actuator toedmg De limit switch trip point ' ] (C8) changes the indication from ih..edisse to shut. j Technicians set the limit switch trip point (C8) during static VOTES testmg to ensure it occurs after hard sest contact (Cll) and prior to the torque switch trip [ point (Cl4). This results in the valve disk c-**daa the hard seat and begmnmg to l I build load before tripping the MOV. However, since all gate MOVs are torque { ter-i (regardless of the ccatrol ..-t.,
. ode:ogy), the final force value (C16) is l 1
o rendent on the higher torque switch value versus the limit switch trip value. In I
- maa, after VOTES testing is complete, e nM=4 remove the limit switch jumper and Operations strokes the MOV (now on limit control). This reduces the j maxunum seating thrust (C16) considerably, but it is not measured.
i Since the torque switch acts on load only, an increase in loadmg prior to reaching the limit switch trip point (as with a design basis flow, line pressure and differential ! pressure) may cause the MOV to trip carher in the stroke but never further than the a limit switch trip point (C8). Under the maximum loading, the valve never reaches l the valve seat and thus wouki require mmimal disk pullout force (09) to unseat. 4 Derefore, the lughest seating thrust is produced during static testmg (plus torque
- switch repeatability and measurement error).
i ne maximum baschne static scatmg thrust (marked C16 on the VOTES trace) is i based on the torque switch trip point plus inertia His makes this value overly conservative for limit controlled MOVs. However, an equivalent thrust based on
- the limit switch trip can be derived.
l To compute this maximum seatmg thrust the followmg is performed Inertaa is } calculated as the difference between the maximum baseline static seatmg thrust and i the torque switch trip point (C16 - C14). This inertza is then added to the value of j the limit trip switch (C8). 10 % is then added for conservatism. Finally, this value d is added to the total error factor based on diagnostic inaccuracies and a limit switch repeatability value of 5% (very conservative). j The followmg table shows the numbers used to calculate the original maxmium j closing thrust (Ttotal -torque) and the revised maximum closing thrust (Ttotal - i torque and limit).

The following analysis shows capability for these valves. The value of CSTuxx calculated in the applicabic thrust calculations (Reference I I and 2) is based upon a valve limit of 24,056 lbs. Reducing the diagnostic tnaccuracies and torque switch repeatability value of 13 %, the limit for the valve
- is 27,650 lbs which is still not sufficient to overcome pressure locking. However, the Velan calculation (Reference 12) lists this value as only limiting in the closing direction. The limit in the opening direction is 46,276 lbs, well above the force needed to overcome pressure locking. Per the thrust calculations, the next limiting component is the motor at reduced voltages,40,471 lbs, which is also above the force required to overcome pressure lockmg J
Conclusion - MOVs have sufficient capability to overcome Pressure Locking. I 1/2-MOV-4516 and 1/2-MOV-4517 The value of CSTuix is based upon thrust at reduced startmg voltages calculated in the applicable thrust calculation (References 45 and 46). These numbers are Page 29 of 36 11/20/95

i 1 l i DOC. I.D. : M 128 i Revision 0 (VI) DISCUSSION / METHOD OF ANALYSIS 1 i i MOVE 3.0 (Motor Operated Valve Evaluation) is a PC based computer I program which evaluates MOV configurations and capabilities. j MOVE is the mechanism that is utilized to calculate design parameters, and ultimately, determine the " Thrust Window". i ( Program requirements, including a description of program inputs, { outputs, and a comparison with an independent solution are documented t 1 in Ref.(3). ' l 4 The calculational results may indicate that the MOV is NOT capable of } adequately performing its function utilizing standard inputs and
- generic assumptions (Section VII.A). It should be noted that initial
} inputs and assumptions are extremely conservative in the interest l 4 of maximizing MOV reliability. i i i If adequate margin can not be obtained, an Intermediate Evaluation i will be conducted (Section VII.B) . This evaluation replaces standard j inputs and generic assumptions with MOV specific data. Also, some conservatisms can be justifiably removed based on actual MOV l performance. Depending upon the extent of relief taken, a hardware f l modification say or may not be required. i i i l 1 1 i j 09/29/94 j 11 of 24 i l i a I J

- Lastly, if the MoV is STILL shown to be inadequately sized after i i
4 completion of the Intermediate Evaluation, an Engineering Evaluation ! I will be performed (Section VII.C) . The objective of this evaluation i , is to assess the operability of the MOV in question. The operability i i assessment may impose operational restraints or limit the life of the t MOV in question. As discussed in detail per Ref.(3), a modification l is required at this stage of the process. This approach ensures that the necessary design margin will be restored, thereby, fully meeting j the intent of maintaining long ' berm MoV reliability. i i 2 In the event that a modification is required (Section VII.B or VII.C I serves as the basis), it will be necessary to determine the j i appropriate replacement as well as the impacts associated with the l modification. The design parameters (" Thrust Window" and " Max. Torque") l
- reflecting the modified configuration will also be established.
l This calculation (Section VII.D) should be sufficient for initiation ! of the modification documentation process. i l 1 l 2 e 09/29/94 j 12 of 24 i 1
i i i f l DOC. I.D. : M 128 i Revision 0 1 f Due to the high probability of existing spring packs no longer being } optimal, it is essential to identify all available spring packs that ! are suitable replacements for the MOV in question. This is a concern l i-due to the fact that Limitorque does not offer functional like-for-like j replacements for the older vintage spring packs (a high percentage of i packs currently utilized at CCNPP). Since many of these packs have not j i yet been replaced, relaxation and/or degradation which is possible j after a long period of time and/or use, render the packs incapable- of l performing as desired. Spring pack testing performed prior to VOTES ~ { f i diagnostic testing will serve as the mechanism to identify existing j packs that are deficient. This evaluation (VII.E) will identify all l available spring packs that are suitable replacements. If any of the suitable replacement spring packs happen to change the design parameters (" Thrust Window" and/or " Max. Torque") , the new j parameters and associated spring pack will be coecified. This
- information, if applicable, will be provided in Section VII.E.

SUMMARY
---===_======
Max TT = 24,056 lbs. CSTmax = 22,745 lbs. ; Maximum Torque = 541 ft-lbs. Tain = 10,295 lbs. Evaluation of the above values indicate that the existing MOV i configuration is adequately-sized to perform its design basis function. However, due to the high-speed operating characteristics of this MOV (i.e. 3400 rpm motor), OVERTHRUSTING is a concern. Proceed to Section VII.D for recommended modifications. 1

t (VI) DISCUSSION / METHOD OF ANALYSIS f l ] MOVE 3.0 (Motor Operated Valve Evaluation) is a PC based computer { program which evaluates MOV configurations and capabilities. 4 i MOVE is the mechanism that is utilized to calculate design parameters and ultimately, determine the " Thrust Window". l Program requirements, including a description of program inputs, ! outputs, and a comparison with an independent solution are documented in Ref.(3). i l The calculational results may indicate that the MOV is NOT capable of adequately performing its function utilizing standard inputs and
- generic assumptions (Section VII.A). It should be noted that initial inputs and assumptions are extremely conservative in the interest of maximizing MOV reliability.
1 i If adequate margin can not be obtained, an Intermediate Evaluation will be conducted (Section VII.B) . This evaluation replaces standard ] l inputs and generic assumptions with MOV specific data. Also, some J4 conservatisms can be justifiably removed based on actual MOV 1 j performance. Depending upon the extent of relief taken, a hardware j modification may or may not be required. i 11/11/93 11 of 25
i i i i DOC. I.D. : M 087 Revision 0 l, l i Lastly, if the MOV is STILL shown to be inadequately sized after completion of the Intermediate Evaluation, an Engineering Evaluation j will be performed (Section VII.C). The objective of this evaluation 1 is to assess the operability of the MOV in question. The operability assessment may impose operational restraints or limit the life of the MOV in question. As discusned in detail per Ref.(3), a modification I
- is required at this stage of the process. This approach ensures that
! the necessary design margin will be restored, thereby, fully meeting l 1 ! the intent of maintaining long term MOV reliability. l In the event that a modification is required (Section VII.B or VII.C serves as the basis), it will be necessary to determine the appropriate replacement as well as the impacts associated with the modification. The design parameters (" Thrust Window" and " Max. Torque' l. reflecting the modified configuration will also be established. This calculation (Section VII.D) should be sufficient for initiation of the modification documentation process. 11/11/93 12 of 25

- Due to the high probability of existing spring packs no longer being optimal, it is essential to identify all available spring packs that
} are suitable replacements for the MOV in question. This is a concern l l due to the fact that Limitorque does not offer functional like-for-li) ' I replacements for the older vintage spring packs (a high percentage of i packs currently utilized at CCNPP) . Since many of these packs have noi i yet been replaced, relaxation and/or degradation which is possible
- after a long period of time and/or use, ronder the packs incapable of I l
i performing as desired. Spring pack testing performed prior to VOTES l diagnostic testing will serve as the mechanism to identify existing l packs that are deficient. This evaluation (VII.E) will identify all available spring packs that are suitable replacements. If any of the suitable replacement spring packs happen to change the 1 j design parameters (" Thrust Window" and/or " Max. Torque"), the new parameters and associated spring pack will be specified. Thul l information, if applicable, will be provided in Section VII.E. i i l l t i l i i i i j 11/11/93 i 13 of 25

I f l Max TT (Maximum Total Thrust)
=====-----====
f i Per Ref.(4), Limitorque allows continuous thrust / torque loads up ! to (1.1) times the unit rating, allowing for inertial loads i beyond control switch trip (CST). MOVE 3.0 does not take credit l for this additional design margin. ! Per Att.3, Max TT (Operator) = 60,900 lbs. l 4 Therefore, the allowed Max TT (Operator) is: l Max TT (Operator) = (60,900) * (1.1) = 66,990 lbs. i j However, this value is NOT as limiting as the " Maximum Valve
- l. Limit" which, per Attachment 3, is 24,056 lbs.
l Max TT = 24,056 lbs. i j j i Prior to static testing, a maximum torque switch setting (TSS) will be assigned. The purpose of assigning this parameter is to ensure that the limiting " Torque" allowable of the operator is NC exceeded. In order to determine the Maximum TSS, the limiting j " Torque" allowable must be identified. f Per Att.3, limiting " Torque" = 518 ft-lbs. (MOTOR 0 RV) i

i l t DOC. I.D. : M 087 i Revision O l D. DETERMINATION AND EVALUATION OF MODIFICATION i i i Section VII.A identified the susceptibility of these MOV's to j "overthrusting" due to their high-speed operating characteristics. { The purpose of this section is to identify the MOV radifications required to alleviate overthrusting concerns.

4 l t To provide a reasonable level of assurance that Inertial loads (loads imparted after control switch trip) will not challange l j component allowables, OPERATOR GEARING modifications are recommended. Increasing the overall Actuator Ratio (OAR) from { i 36.99 to 82.50 via motor pinion and worm shaft gear replacements j will significantly reduce inertial loads. l I 1 IMPACTS : (a) As a result of the proposed OPERATOR GEARING j modifications, the MOV calculated stroke time i 4 will increase from 63 sec to 140 sec (per Att.3). (b) The slower MOV will decrease the inertial loads, thereby, enhancing the ability to satisfy the 1

DOC. I.D. : M 087 Revision 0 provides a MOVE 3.0 printout of the calculational results reflecting the proposed modified configuration.

*Due to the'high-speed operating characteristics of this MOV, l overthrusting is a concern. To provide a reasonable level of assurance l
j l l
- that inertial loads will not challange component allowables, OPERATOR 1
l GEARING modifications are recommended. Increasing the Overall Actuator Ratio (OAR) from 36.99 to 82.50 via motor pinion and worm shaft gear l replacements will significantly reduce inertia loads. 1
- As a result of the proposed modifications, the MOV calculated stroke time will increase from 63 see to 140 sec.
