  • 4.0 PROGRAM METHODOLOGY 4.1 Determination of Maximum D/P For the valves listed. on Attachment 1, the limiting condition for Differential Pressure shall be determined.by the CE Owners Group and verified by plant engineering personnel. This verification may include adjustments to the differential pressure value as a result of plant arrangements or system parameters. For the valves listed on Attachment 2 and Attachment 3, the determination shall be performed by vendor or plant engineering personnel. During this determination the factor listed in 4.1.1 thru 4.1.6 below should be taken into consideration. Record completion on Table 1.

4.1.1 Pump suction and discharge conditions 4.1.2 Safety relief valve setpoints 4.1.3 Operational requirements under various conditions such as plant startup, normal plant operations, platn shutdoWn.,

plant emergency operations, special or infrequent opera-tions and system abnormal or emergency operations.

4.1.4 FSAR and technical specification conditions for the system and valve *

  • 4.2 4.1.5 4.1.6 Inadvertent equipment operation.

Whether the valve is to open or close against a full flowing system.

Data Base. Verification Data base verification is performed by conducting a visual.inspection of each valve and valve operator and recording data on Attachment 4.

Verify and update the AMMS data base for each valve and actuator, Record completion on Talbe 1.

4.3 As Built Data Collection Submit a written request to Limitorque Corporation to provide the information listed on Attachment 5 from the original ordering data for each motor operated valve. Record completion on Table 1.

4.4 Thrust Calculations 4.4.1 Conduct preliminary thrust calculations for each motor operated valve to verify sizing of the motor operator.

These calculations are performed in accordnace with paragraph 4.4.1.a thru 4.4.1.c below. Attachment 6 is a sample calculation.

MI0687-296A-MA05

  • NOTE:

4.4.1.a These calculations are conducted using average values for various factors as specified by the Limitorque Corporation sizing procedure. Actual required thrust values may differ due to actual factors for specific valves being different.

The thrust required to operate the valve during the design conditon will be calculated using the following formula which is derived from the Limitorque Corporation selection procedures (References 3.6.1 thru 3.6.6).

Thrust = Maximum D/P X Seat Area X Valve Factor + Stuffing Box Load + Stem Load NOTE: . The stem load (piston effect) is the force required to drive the valve stem into the valve. Although this force is not always present in globe valves in the terms de-scribed below, this factor will be included in all calcu-lations as a conservative measure.

As explanation of these terms are as follows:

Maximum D/P =Value obtained during paragraph 4.1 above.

Seat Area = Actual valve seat area subjected to the maximum

6 4.4.1.b In order to determine torque switch settings and as an aid in evaluating the condition of the actuator and valve, the output torque should also be calculated. Per Reference 3.6.2, required output torque necessary to provide the calculated thrust is determined as follows:

Torque = Thrust X Stem Factor The stem factor is obtained from the Limitorque Selection Procedure (Reference 3.6.6). A coefficient of friction of 0.20 is used to provide a conservative value to account for the possibility of poor maintenance and lubrication of the valve stem and stem nut threads. The correct stem factor is determined using the actual stem diameter, pitch and lead determined during paragraph 4.2 above.

4.4.1.c Using the data obtained during paragraph 4.3 above or an actual spring pack calibration curve for the applicable motor operator obtained during maintenance, verify the torque switches are set at the appropriate values to produce the required thrust.

4.5 Valve Vendor Thrust Recommendations 4.5.1 Submit a written request to the appropriate valve vendor to

  • 4.5.2 provide the information listed on Attachment 7. Record completion on Table 1.

Following receipt of the information requested in paragraph 4.5.1 above, compare the thrust. requirements to those calculated in paragraph 4.4 and resolve any deficiencies.

Verify each motor operator is correctly sized to produce the required thrust. If the operator is not correctly sized, provide the necessary information to Limitorque Corporation to obtain their recommendations for replacement parts (ie. gears, spring assemblies or motors). Process spec changes as neces~ary to authorize part replacement.

4.6 Operator Refurbishment and Testing NOTE: The actions specified in paragraphs 4.6.1 thru 4.6.6 shall be conducted during the 1987 maintenance outage for valve listed on Attachments 1 and 2.

4.6.1 At the earliest possible opportunity conduct an "as found" diagnostic test of each motor operated valve included on Attachment 1. If conditions permit, this test may be performed prior to plant shutdown. The purpose of this test is to demonstrate the as found operability of the motor operator. In addition the results of this test will aid in troubleshooting any possible deficiencies noted

  • MI0687-296A-MA05

7 4.6.2 If the motor operator has been overhauled recently prior to the 1987 maintenance outage, conduct the preventive maintenance specified in MSM-M-26, MSM-M-27 or PPAC's, as applicable, and correct any deficiencies noted. In addition, the belleville springs assembly may be removed and tested to determine the spring pack calibration curve for the specific spring assembly. Verify operator orien-tation is such to prevent grease buildup in the belleville springs assembly causing hydraulic lock.

4.6.3 If the designated motor operator has not been overhauled recently prior to the 1987 maintenance outage, disassemble, inspect and overhaul the operator in accordance with MSM-M-26 or MSM-M-27 as applicable. During this overhaul test the belleville springs assembly to determine the spring pack calibration curve for the specific spring assembly and verify operator orientation is such to prevent grease buildup in the belleville springs assembly causing hydraulic lock.

4.6.4 Perform the actuator modifications necessary as a result of paragraph 4.5.2 above during the performance of steps 4.6.2 or 4.6.3 above.

4.6.5 Perform an "as left" diagnostic test of each motor oper-

  • 4.6.6 ator. Adjust the switch settings as necessary to ensure the operator will produce 110% to 120% of the minimum thrust required to operate the valve at maximum D/P.

For those valves listed on Attachment 1, verify the ability of the operator to perform its design function at maximum D/P by performing Palisades test procedure T-249 or Palisades Test Procedure T-250 as applicable. Monitor valve performance with a diagnostic machine during perfor-mance of the test. If insufficient test machines are available to monitor all valves during a test sequence, monitor the operators that produced an operating thrust closest to the required thrust during* the as left diag-nostic _test of paragraph 4. 6. 5 above.

If the Movats data base for valve operation against a DP is sufficient to include these valves, the data base may be substituted for performance of these tests.

If data obtained during differential pressure testing of one "train" of valves in 2 redundant systems is sufficient to justify not testing the other train, the differential pressure testing of the second train may be def erred to a later outage.

Stem load is calculated as follows:

  • Stem load* line pressure X stem area Required actuator torque necessary to produce the calculated thrust is determined as follows:

Torque

  • thrust X stem factor
3. Assumptions a) Major Assumptions These calculations are performed assuming the Limitorque operator an~the valve installed have not been modified and are in fact the same as specified in paragraph 2 above, and are in good working order. In addition it is assumed the installed HPSI pumps will not produce a shutoff head in excess of 1245 PSI.

b) Minor Assumptions The stem load term, although not a factor during valve opening, is included in these calculations to provide a conservative factor.

4. Analysis Below is a listing of the values used for each term in the calculation and a basis for each:

Maximum D/P

  • 1238 PSID - Shutoff head of the HPSI pumps (corrected for elevation) vs. atmospheric pressure (ie.: line break between the PCS and MOV). Obtained from the CE Owners Group calculations.

Seat Area

  • 13.36 sq.in. - Obtained from Anchor-Darling Valve Company drawing 8494-01.

Valve Factor* 0.3 - Standard value used for all wedge.type gate valves.

NUCLEAR OPERATIONS DEPARTMENT EA -KR.K-lH-001 Analysis Continuation Sheet Sheet _3_of __i_

Obtained from the Limitorque Corporation sizing procedure

  • (SEL-3) per reference 2.

Stuffing Box Load

  • 2500 lbs. - Average value for stems between l 1/2" and 2 1/2" in diameter. Actual stem diameter of l 3/4" verified by visual inspection. Load value obtained from the Limitorque Corporation sizing procedure (SEL-3) per reference 2.

Stem Area* 2.404 sq.in - Calculated value based on a 1 3/4" stem diameter.

Line Pressure

  • 1238 PSI - A conservative value based on the shutoff head of the HPSI pumps. This term would not be necessary during the conditions of maximum D/P during valve opening as defined in this EA, however, it is included as a consrevative factor.

Stem Factor

  • 0.0210 - Obtained from the Limitorque Corporation sizing procedure (SEL-10) per reference 2. This value is off the table assuming a coefficient of friction of 0.20 which accounts
  • for the possibility of poor maintenance and lubrication of the stem and stem nut threads. A stem diameter of 1 3/4" with a l/4 pitch and l/2 lead, all verified by personnal observation, were used in determining this factor.

Under these conditi~ns, the minimum required thrust necessary to operate this valve during the postulated accident conditions is calculated as follows:

Thrust

  • 1238 X 13.36 X 0.3 + 2500 + (2.404 X 1238)

Thrust

  • 10,438.06 lbs.

Torque

  • 219.20 The current torque switch settings specified by the Limitorque Corporation for this actuator are as follows:

Normal 'nlis setting will produce a torque of 300 ft.lbs. with a thrust of 17,053 lbs.

Form 3250 4-83 NUCLEAR OPERATIONS DEPARTMENT EA -KBK-87-003

(@E' Analysis Continuation Sheet Sheet_Lof _L Maximum This setting will produce a torque of 300 ft.lbs. with a thrust of 17,053 lbs.

5. Conclusion The thrust currently produced by this actuator (17,053 lbs.) exceeds the minim.um required to operate the valve during accident conditions, therefore, no immediate action is necessary. Upon verification of the thrust calcu~ations of this EA with the valve vendor, this EA will be ammended to provide the correct torque switch settings to provide the minimum required thrust.

this torque*valua is based on a properly maintained and lubricated valve stem and stem nut. Although these conditions will be present during diagnostic testing and switch setting following the 87 maintenance outage, some degragation of the stem and stem nut conditions will occur prior to the next scheduled lubrication maintenance (18 month frequency). Therefore the required torque will be modified to ensure the minimum thrust will be produced even with 11. poorly maintained stem and stem nut.

As specified in reference 2, the torque/thrust relationship for a specific valve is determined as follows:

Torque

  • Thrust x stem factor In order to ensure operability with a poorly maintained stem and stem nut a stem factor based on a coefficient of friction of 0.2 will be used. In order to produce the required thrust with a poorly maintained stem and stem nut the necessary torque would be calculated as follows:

Torque

  • 223.44 ft.lbs.

Since torque switch setting will be conducted using a MOVATS diagnostic unit to determine stem thrust with a properly lubricated stem and stem nut the target thrust must be increased to ensure sufficient thrust will be produced under degraded conditions. This value is calculated by converting the necessary torque under degraded conditions to thrust produced under ideal conditiona as follows:

Torque + stem factor

  • Thrust 223.44 + 0.0175
  • Thrust 12, 768
  • Thrust It is also necessary to provide an additional margin to allow for inaccuracies of the diagnostic machine and repeatability of the operator and torque switch.

In this case the required thrust will be multiplied by a factor of 1.1 to provide this margin.

5. Conclusion Setting the torque switch on VOP-3080 to produce a minimum thrust of 14,045 lbs.

following maintenance will ensure the operator will produce at least 11,704 lbs.

under degraded stem and stem nut conditions. To provide a setting tolerance and still provide a safety margin to prevent exceeding the yield of the weakest valve member as specified in reference 3, the torque switch should be set to produce a thrust value as stated below:

6. Alternate Calculations Parameters identified by both the valve and operator vendors were used as inputs to B&W's comp!-lter program "MOVE" (Motor Operated Valve Evaluation) in order to verify the valve vendor's thrust and torque values. A comparison of the results is shown below.

Vendor Results MOVE Results

.Thrust 10.640 lbs

  • 11,385 lbs.

Torque 186.2 ft.lbs. 198 ft.lbs.

As seen above, there exists a disparity between the vendor and move values.

However, this difference is due to the stuffing box load used in the two evaluations. The valve vendor used 1750 lbs., whereas MOVE used 2500 lbs.,

a value identified by Limitorque methodology. It should be noted that both values are acceptable. If the move analysis used the 1750 lbs. _load, it would produce the following: .

thrust ~ 10,635 lbs. Torque

  • 185 ft.lbs.
