1.0 PURPOSE l

This procedure provides instructions for the Static or Dynamic testing of motor-operated l

valves (MOVs) using Liberty Technology's Valve Operation Test and Evaluation System (VOTES). This procedure is to be followed in order to comply with the requirements of NRC Geneeric Letter 89-10 to verify, trend and track MOV performance and/or ability to perform i

its intended safety function.

l NOTE:

As a matter of practice, the first "as left" test on a valve is considered the baselirte test. Each subsequent test is compared to the baseline test for i

trending and evaluation. A new baseline test should be performed as soon as possible after any major work which may be done on the valve or operator which may change the valve's baseline characteristics. This may t

include but is not limited to: valve disassembly, reseating, repacking, stem replacement, MOV gear, bearing, bearing housing gaskets, torque switch or stem nut replacements.

i 2.0 PRECAUTIONS AND LIMITATIONS 2.1 Review applicable Radiation Work Permit (RWP) for regt.irements in the work area.

l 2.2 Do not allow the entry of foreign materials into working parts of the valve operator.

2.3 Only individuals that have completed VOTES Training / Certification or individuals under the direct supervision of qualified personnel may operate the VOTES equipment.

(

i 2.4 Only individuals that have completed VOTES Signature Analysis or MOVATS Signature

.l Analysis training may perfc.m Signature Analysis for purposes of completing the Degradation Data Sheet, Attachment 2.

L 2.5 Ensure all power connections to VOTES System are 120Vac,60 Hz.

2.6 Ensure the VOTES System is deenergized while installing test equipment, associated sensors and wiring connectors to prevent voltage / current spikes from damaging the

-[

computer / test equipment.

2.7 Do not operate computer in area where ambient temperature is less than 50 F or I

0

~

0 greater than 104 F.

f 2.8 When a problem or nonconformance is noted, work shall stop if the testing is l

detrimental to the valve or system. Notify the NSS to ensure that required

{

deficiencies are resolved before a valve is returned to service All deficiencies noted shall be listed on the Work Request as appropriate.

[

i 2.9 If there must be jumpers installed or wires lifted to stroke valve, the use of an Interim Alteration Checklist is required.

2.10 As-Found signatures should be acquired before altering setting of torque switch or i

limit switches.

2.11 Electrical circuits associated with MOVs cannot be isolated during certain plant conditions. These must be identified prior to work.

i f

l

i 47.306.02 Revision 5 Page 3 2.12 The following improper actions may damage MOV actuators:

l 2.12.1 Lifting the actuator by the handwheel.

2.12.2 Use of excessive force on the declutch lever when engaging into manual l

drive mode.

i 2.12.3 Use of excessive force on the declutch lever in attempt to return the actuator to the electrical operation position. Internal damage is possible.

j 2.12.4 Use of,nauthorized mechanical lever on the handwheel to seat or unseat the valve could cause damage to actuator and valve.

l 2.13 The sequence and method of testing may be repeated or a.'tered at the discretion of the Test Leader to ensure complete data acquisition for subsequent signature

.l analysis. Re-tests may be performed under this procedure provided the tests are sequentially numbered and each is documented on a separate consecutively numbered Test Data Sheet, Attachment 1.

2.14 If during performance of this procedure, it is discovered that actuator rework is l

required, it should be done in accordance with Procedure 35.306.006, Enclosure C.

2.15 If during performance of this procedure, it is discovered that the' VOTES Force Sensor is not properly attached to the valve yoke (e.g. not preloaded), it shall be removed i

and a new sensor installed per 35. LIM.009.

2.16 Any discrepancies noted during the conduct of this procedure must be reported to the appropriate Supervisor for disposition.

2.17 Verify duty cycle for each valve is followed.

2.18 As steps are performed / completed, the boxes at the end of the step may be checked i

off (optional).

j 2.19 Ensure calibration device will fit the valve stem (e.g. mini C Clamp - 1 1/8 inches

[

max, C Clamp - 17/8 inches max [or 21/4 inches for newer style], D Clamp - 31/2 inches max, U Clamp 51/2 inches max, maxi U Clamp - 8 inches max).

t 2.20 Use of the computer / printer in an " Airborne Radioactivity

• or " Loose Surface Contamination" area may result in internal contamination of the computer / printer due -

i to the requited cooling air flow through the computer / printer, 2.21 A short adapter cable is provided to conr.ect cable from the Breakout Box to Signal l

Conditioning Box. Every attempt should be made to locate the short cable at the Signal Conditioner Box to avoid its contamination. Up to 500 ft. of signal cable can -

be used between Breakout Box and Signal Conditioning Box.

2.22 A Torque Switch Transducer (TST) or a Thrust Measuring Device (TMD) may be f

utstized if needed to determine spring pack displacement. This will normally be utilized in a spare channel in the breakout box.

2.23 The VOTES Technical Manual can be utilized as a reference for guidelines on this l

testing.

Revision 5 Page 4 i

2.24 If the maximum values as contained in the test data sheet are exceeded, the valve shall be declared inoperable either until the valve is adjusted within the limits or Nuclear Engineering analyzes and accepts the out of specification condition'.

2.25 An *as found" LLRT should be performed prior to any adjustments, repair, or enhancements to the valve, packing gland, stem or operator. This includes but is not timited to stem lubrication or nut tightening.

2.26 in some cases, to perform a sensor calibration, it may be necessary to loosen and remove the packing gland nuts or follower to prevent calibrator clamp interference.

The performance of this on an LLRT valve will inop the valve and invalidate the valve's LLRT results. Ensure the Test Supervisor is notified PRIOR TO loosening the gland nuts to assure that the *as found" LLRT results are not jeopardized and that a i

• post" LLRT can be performed immediately after the thrust test.

t 2.27 Peak motor seating current should not exceed 60% of locked rotor amps (LRA) on safety related MOVs. This value is the " Rule of Thumb

• and if exceeded, must be evaluated in the Degradation Data Sheet, Attachment 2. Exceptions to this

• Rule of i

5.4 Calibrating the VOTES Force Sensor NOTE (1):

The calibration procedure must be performed at least twice for every sensor mounted on a valve yoke. The calibration procedure should be j

repeated if the close torque switch setting has been changed by greater than one (e g. from 2-1/2 to 1-1/2), if ;he actuator body or valve has been physically altered, a new VOTES sensor installed, or a l

new stem has been installed.

NOTE (2):

In some cases, to perform a sensor calibration it may be necessary to l

loor,en and remove the packing gland nuts or follower to prevent calibrator clamp interference. The performance of this on an LLRT I

valve will inop the valve and invalidate the valve's LLRT results.

l Ensure the Test Supervisor is notified PRIOR TO loosening the gland nuts to assure that the "as found" LLRT results are not jeopardized and that a " post" LLRT can be performed immediately after the thrust test.

CAUTION l

Loosening and removing packing gland nuts will invalidate the valves LLRT.

i f

CAUTION C-clamp must not strike any portion of valve during calibration or it will be damaged. It should be attached to valve stem in a position free of interference with other valve components so that there is sufficient clearance during seating, taking into account slight stem rotation during operation.

NOTE:

Whenever possible position the clamp bridging the anti-rotation slots.

2.

For gate valves, place the valve in an open-stressed condition. The perfect condition is just before disc pullout. This will mean that the valve never gets fully unseated.

j I1 3.

For globe valves, fully unseat the valve, ensure cal stroke is done after handwheeling in open direction.

5.4.9 Calibration of VOTES Force Sensor using D-clamp. U-clamp, or maxi U-clamp.

1.

Connect DC Voltmeter to test points on Proximetor Box and verify initial gap voltage is -5.5 volts DC 4/- 0.25 volts for U or maxi U-clamp or -12.0 +/ 20 volts for the D-clamp. If the gap voltage -

does not fall into this range, reset the Proximity Probe.

II NOTE:

As used in this section, U-clamp refers to either the D-clamp. U-clamp or maxi U-clamp.

CAUTION Do not mount U-clamp on the unthreaded portion of stem within 1 stem diameter of the transition point from threaded to unthreaded, or 1/2 stem diameter into the thread. See Enclosure 8 for illustration.

2.

Clean that portion of the valve stem where the U-clamp is to be attached using an approved degreasmg solution.

[]

I CAUTION 1

Loosening and removing packing gland nuts will invalidate the va!ves LLRT.

CAUTION U-clamp must not strike any portion of valve during calibration or it will be i

damaged. U-clamp should be attached to valve stem in position free of interference with other valve components so that there is sufficient axial clearance during seating, taking into account slight stem rotation during operation.

5.4.10 Trace point selection for sensor calibration.

1.

Ensure the two traces follow each other. If one plot levels off before

{

the other plot, the device whose plot leveled should have its gain reduced and the test re performed.

I]

2.

Votes uses automatic spike suppression / removal for the cahbration t

traces, but it is still a necessity to redo test which display a significant amount of noise.

[]

3.

The two traces should show an initial sharp change from a stem f

tension condition to a transition area then another sharp change as l

the valve seats. The first priority is to find and mark the "zero* force spot (this is essentially the same point as the C3 mark placed on full stroke traces).

!I s

4 Next, with the cursor on the initial flat line area to the left (before the first sharp change) press F3-Mark to place the left boundary mark for calculation. Move the cursor to the far right flat area (just after the j

sharp seating slope) and press F3-Mark to establish the right side boundary. Now, press F10-Continue to allow the computer to calculate the correlation slope.

CFA - Curve Fit accuracy

[]

6.

For the calibration to be acceptable the CFA must be between.970 and 1.00. If CFA is within that acceptance criteria then the value of f

RSO is meaningless. If true zero value had not been identstsed (or marked) then an N/A will appear after CFA, which makes an RSO value the determining factor for meeting the.970 - 1.00 acceptance criteria.

In that case it is also highly desirable to make every effort to obtain an RSO of at least >.997, so that system accuracy is not degraded.

[]

i 7.

If the values are acceptable save the calibration to the hard disk then repeat the calibration to verify that the two slope values (BFSL sens) i are within 5% of each other. Record the applicable values on the test data sheet. If the second calibration had a better CFA (or RSO) then save it to the hard disk, which overwrites the first cal. If the first cal had better values then simply do not save the second test.-
