d' The allowable ranges specified in Table IWP-31'00-2 will be used for differential pressure, flow, and vibration measurements except as N'r provided for in relief requests.- In some cases, the performance of a 1
pump may be adequate to fulfill its safety function even though there may be a measurement that falls outside the allowable ranges as set 4
forth in Table IWP-3100-2.
Should this situation occur, an expanded i
- a.llowable range may be detemined, on a case base, in accordance with IWP-3210 and ASME Code Interpretation XI-1-79-19.-

3.1. 6 Cold Shutdown Testing For;those valves' designated to be exercised or tested during cold shut,fown, exercising / testing will commence as soon as practical after the t.lant reaches a stable cold. shutdown condition as defined by the Ranche, Seco Technical Specifications.
Due to scheduling and manning limitations, such testing may not be performed for cold shutdown periods that are not. expected to exceed 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br />.
Furthermore, valve testing will'not necessarily be performed more often than pnce every three (3) months.
Completion of all valve testing during a cold shutdown' outage will not be required if plant conditions preclude-testing of specific valves or.if the cold shutdown period is insufficient to complete all testing.
Testing not completed before startup,may be completed during subsequent cold shutdown outages.-
.A d t onal restrictions may be applied as stated in specific dii Note:
relief requests.
Refer to Appendix C of this Program for cold shutdown justifications.
3.1.7
~ Position Indication Testing For those valves with remote position indicators, tests will be performed to ensure the indication correctly reflects actual valve positico and operation in accordance with the requirements of IWV-3300.
3.1.8 Fail-saf e Tesi.ing The normal methods for exercising power-operated valves also tests the failsafe functions of these valves if they exist.
Thus, no additional testing is required and the respective cold shutdown justifications and relief requests apply to the requirements of paragraph IWY-3415, when applicable.

Loose cpupling sleeves are notorious troublemakers, especially in conjunction with long, heavy spacers.
Check tooth fit by placing indicators on top then lift by hand or a jack and note looseness (should not be more than 1-2 mils at standstill, at most).
Use hollow coupling y
spacers.
Make sure coupling hubs have at least 1 mil / inch interference i
fit on shaft.
Loose hubs have caused many shaft failures and serious vibration problems.
21.
Try field balancing more viscous oil (colder); larger, longer bearings with minimum clearance and tight fit; stiffen bearing supports and other structures between bearing and ground.
This is basically a design problem.
It may require additional stabilizing bearings or a solid coupling.
It is difficult to correct in the field.
With high-speed machines, adding mass at the bearing case helps considerably.

These are criti.cals of the spacer-teeth-overhang subsystem.
Often encountered wi'rh long spacers.
Make sure of tight-fitting tooth with a slight interference at standstill and make the spacer as light and stiff as possible (tubular).
Consider using a solid or membrane coupling if
-the problem is severo.
Check coupling balance.
23, ' Overhang criticals' can be cxcoedingly troublesome.
Long overhands shift the nodal point of the rotor deflection line (free-free modo) towards the bearing, robbing the bearing of its damping capability.
This can make critical speeds so rough that is is impossible to pass through them.
Shorten the overhang or put in an outboard bearing for stabilization.
24.
Casing resonance is also called " case-drumming." It can be very j
persistent but is sometimes harmless.
The danger is that parts may como i
loose and fall into the machine.
Also, rotor / casing interaction may, be involved.
Diaphragm drumming is serious, since it can cause i
catastrophic failure of the diaphragm.
25.
Local drumming is usually harmless but major resonances, resulting in vibration of the entire case as a unit, are potentially dangerous because of possible rubs and component failures, as well as possible I
excitation of other vibrations.
26.
Similar problems as ip 24 and 25 with the added complications of settling, cracking, warping and misalignment.
This cause may also produce piping troubles and possible case warpage.
Foundation resonance is serious and greatly reduces unit reliability.
ss 27.
Prnssure pulsations can excite other vibrations with possible serious consequences, Eliminate such vibrations using restraints, flexible pipe foundation, sway braces, shock absorbers, etc., plus isolation of the

Occurs most,1y at two times line frequency (7,200 cpm), coming from motor and generator fields.
Turn the fields off to verify the source.
Usually harmless, but if the foundation or other components (rotor 1
critical or torsional) are resonant, the vibrations may be severe.
There is a risk of catastrophic failure if there is a short cirduit or other upsets.
29.
This can excite serious vibrations or cause bearing failures.
Isolate the piping and foundation and use shock absorbers and sway braces.

Such vibrations are aerodynamically excited.

i 31.
The vibration is exactly one-half, one-quarter, one-eighth of the exciting frequency.
It can only be excited in nonlinear systoms, therefore, look for such things as looseness and aerodynamic or hydrodynamic excitations.
It may involve rotor " shuttling." If so 4
check the seal system, thrust clearances, couplings, and rotor-stator clearance effects.
32.
The vibrations are at 2x, 3x, 4x exciting frequency.
The treatment is l
the same as for direct resonance:
change the frequency and add dampirg.
33.
If the cause is intermittent, look into temperature variations.
Usually the rotor must be rebuilt, but first try to increase stator damping, add larger bearings (tilting-shoe), increase stator mass and stiffness, improve the foundation.
Thi's problem is usually caused by maloperation
{
such as quick temperature changes and fluid slugging.
Use membrane-type coupling.
l 34.
This is basica.lly a design problem but is often aggravated by poor i
balancing and a poor fo,undation.
Try to field-balance the rotor,at operating speed, lower oil, temperature, and use larger and tighter i
bearings.

" motor load" data. Results of the analysis may be used to estaolish 4
operability limits and to identify mechanical and electrical degradations in motor operated valves.
NOTE:
The motor load unit may be used at the operator if electrical leads to the motor are landed on a terminal strip i in the operator housing.
(The unit cannot be used at the operator if motor leacs are sealed with "Raychem" type connectors.)
A.
Attach the input cable to the motor load unit.
B.
Before connecting the motor load unit to the operator, locate the non-reversing phase on the terminal strip (usually the center terminal).
C.
Connect the red lead from the motor load unit to the terminal for the non-reversing phase. Then connect the while and blue leads to L

Clamp the Fluke current probe around the motor lead associated with non-reversing phase. The Fluke probe must be positioned such that the arrow on the label points toward the motor.
E.
Plug the two-conductor Fluke cable into the Fluke probe while ig) observing the polarity markings on the cable and Fluke.
(The Black socket on the Fluke is ground.)
GAUTION:
If the Fluke is placed on a reversing motor phase, is installed with the arrow pointing away from the motor, or is connected with reverse cable polarity, the unit will not s
verk properly.

Connecting the Motor' Load Unit at the Motor Control-Center (MCC) 1 A.
The steps for connecting the unit at the MCC are the same as' the J:
valve, but with the following constraints and precautions.
3 8.-
The.non-reversing phase must be identified by' careful review of the j
internal MCC wiring.
C.
The Fluke probe must be installed as far'as possible from hnt p
transformed or other sources of strong magnetic fields in the-1 MCC.. The termination compartment beside the MCC (if present) is the preferred point for Fluke attachment.
J D.
The switch. sensing leads must be attached to monitor conactor coil:
J voltage and valve position indication circuits that can be related to limit switch position changes. Plent wiring diagrams must be
,1 used to determine where to attach <these sensing leads.
