I. ABSTRACT A wattmeter has been used on two occasions to determine "in" rod position and on many other occasions in the recent past to establish conditions such as freedom of motion, high loads, or other abnormal parameters. A request was made in the near past to justify the basis for this test; the following document.

provides a sound technical basis for the use of this test.

II. BACKGROUND When a control rod is shimmed in either direction, the drive motor is activated which in turn raises or lowers the absorber pair via a gear _ train and wire rope riding _over a drum and guide pulleys to the absorber pair itself. Normal mechanical losses (bearing, gear, pulleys, seal, etc.) in addition to absorber weight represent a load on the motor against which work must be.

done when the rod pair is raised. In addition, I2R losses in the motor represent a regular electrical loss. The result of these is that movement of a control rod pair in either direction causes distinctive transients which, to a knowledgable observer, contains a multitude of information that goes far beyond the provided instrumentation (motor overload trip, etc.) and can be i used in unusual circumstances to establish condition and location (in some specific cases) of the absorber pair.

III. DESCRIPTION - TRANSIENTS IN/ CUT A typical shim wattage transient always includes (in and out) a jump in wattage to a peak as the mechanism accelerates, a reduction to an approximately steady value in 5-10 seconds, and a steady (but slowly varying) wattage for the shim duration as the cable winds or unwinds on the drum sheave. The shim always terminates with a decay in wattage to a zero baseline in 5-10 seconds.

3 The theory for this behavior is as follows: the shim motor consists of a 4 pole, 3 phase induction motor. A capacitor bank is paralleled across the motor winding phases, but has no effect on torque when the unit is driven from the AC power supply, since the bank's only effect is to change power factors. An induction motor develops torque by the principle of rotor slip; 4

it is assumed that the reader is' familiar with this idea. The greater the slip, the larger the induced fields on the rotor, the larger the torque, and the larger the electrical load.

Wattage will increase rapidly for a freely-moving mechanism as

, the transient begins, and the rotor and mechanism acclerate. As -

the driving torque is developed, the rotor approaches steady speed (corresponding to some steady slip value), and the wattage declines to a steady value.

<s e Ai, s.cc efm)

Note that, for no load on the motor (i.e.; such as during a bench test), a positive power consumption results due to I2R losses in the stator windings and bearing friction, which should be the same in either direction, i.e.;

p ...w CW oc.w i

il n

This is a useful reference item for the following discussion.

For an outward shim, the opposing weight of the rod pair causes more slip due to the greater rotor load. Hence the rotor-stator field interaction is greater, greater current demand on the stator occurs, and a higher motor load results.

i For an inward shim, the assisting weight of the rod pair causes less slip, tending to drive the rod in. (Note that the direction is reversed.) In this case, a reduction in the field interaction occurs, and less motor load results (or equivalently, tne operating point is closer to the synchronous speed).

4 Note that if the motor could be driven externally at exactly synchronous (stator) field speed,'n_o load would result, and any

~

power consumption -would represent only the 18R losses of the stator field.

j- Also n'ote that physically, .one expects a higher lo'ad for an outward shim, when the motor must do work against gravity in addition to.its own internal. losses, than an inward shim, where work is actually done on the motor.

Note also that for an inward shim, again, the mechanism inertia .

- means that instantaneously after the start of the shim, the 4

rotor fields are moving slower than the stator fields. In this

-case, however, both the gravity torque and the developed torque assist to accelerate the rotor in the "in" direction, so that the transient duration is shorter (i.e.; the "in" shims tend to i

be more sharply peaked than the "out" ones).

Average of nominal in/out steady values; 90 + 46 = 136 watts or 68 watts.

2 2 The work done raising the control rods, neglecting 18R losses, and neglecting any frictional load (from viscous drag on the absorber pair, drag in the graphite / guide tube channels, and

. gear train losses), should be less than 90 watts. The following check, assuming no frictional loss in the mechanism confirms this.

Nominal speed 1.05 in/sec ( 190 in )

= 28.5 watts Hence 90 - 29 = 61 watts represent the nominal electrical and mechanical losses in the system. For a mechanical transmission ~

efficiency of 90% per mesh, and a motor efficiency of 80% (both nominal values for similar equipment), the expected out shim power would be 28.5 watts 0.8 (0.9)* = 54.3 watts.

This compares with an observed range of steady values varying from 80 to 110 watts from all testing, for outward shims.

Hmin)

Instantaneously, a shim, since the'~ drum'is not wound, does no work against the rod pair weight; i.e., until the drum reaches one quarter turn, the motor is not working fully against the weight of the rods, as the moment load has not completely -

developed. The distance travelled by the rods is d= C = 23r = _23(6 in) = 9.42 inches, and 4 4 4

. t = 9.42 inches = 9 seconds.

For the last 5 seconds on an "in" shim, or the first 5 seconds on an "out" shim, a change in the steady wattage value should be seen; this is the observation. All "in" shtms terminate with the following:

Final _1y, note-that the direction of drum rotation is irrelevant.

If the motor could be driven in beyond the "in" limit switch ,

cutoff position, the rod pair would be raised as the mechanism wound around the drum in the reverse direction. In this case, an "in" shim transient should appear as an "out", and vice versa.

i It is on these observations that the wattage Verification of rod

position incorporated in TSP-30 (proposed) is, based.

Objectives F'i rst , the test must verify freedom of rod motion. .

Second, it must establish position for rods as- being in ,

(not just cam drum or equivalent pulley position). Third, O

. it should establish that both rods are supported on the- O mechanism, if possible (actually, this is only " nice to

~

i;l) ahave"). '1 The wattage test establishes freedom of gear train motion obviously; impeded motion or locked rotor conditions are i easy to identi fy. Rod motion is determined by' observing correct nominal values for_ in/out shims, with- the magnitude of the out wattage in excess of 78 watts, (if, in fact, both strings are supported). A steady value of d

less than 68 watts should be taken as evidence that one -

. rod is not supported, particularly in conjunction with slack cable indication.

Background

TSP-30, Evaluztion of Shim Motor Wattage Characteristics,

.is the culmination of an extensive review of all h '

applications of wattmeter testing performed in the past, particularly that done under T-214,. Wattmeter Testing. As-  %

a result of an intense examination, a number of -

clarifications and conclusions can be made.

Refer -to Attachments 1-4. These represent a summary of measurements-of data on shim transients collectec;i under .

T-214 in two general time periods. The first was post-third refueling, from about- March 11, 1984 to.

April 15, 1984; the -second- was ' post June 23, 1984

Failure-to-scram Event,y ~ collected June 23, 1984 to June.25, 1984. There ?rtcains additional data collected from July 1,1984 through November 1,1984 which was taken on mechanisms in the Fot Service Facility, primarily, and has not been extensiveiy evaluated. It appears,- from prel,iminary review, to be completely consistent with the other data, very sidilar to that collected in the March 11, 1984 to April. 15, 1984 time period.

s 6. An "out" shim transient starting at the' fully

$' other "out" shim transient. Two aspects of the transient are different - the peak wattage value In almost all cases the -

and the rate of decay.

. rate of the transient decay is so much faster that a pronounced " dip" in wattage below the final steady-state value is observed, due to the winding off the drum sheave phenomena; in every case, the decay to the steady value is significantly faster.

7. An "in" shim transient terminating at the fully -

inserted position exhibits a distinct rise. in steady wattage value as the drum sheave unwraps not observed at any other location.

3; Even on mechanisms with poor wattmeter traces, the above behavior is distinct from other transients since the results can be repeated (i.e.,

spontaneous variations in the wattage record of a poor rod are not duplicatable).

9. A mechanism with only one absorber pair supported will have an "out" steady wattage of about 60 watts, based on Instrumented -Control Rod Drive (ICRD) data.

12. Variations in' voltage at the MCC can have a significant effect on the. level of all values observed. For effective' . test results, voltages should be at 105 nominal' phase-to ground RMS volts.

13. Although T-214 did not have provision.for voltage measurement and control, cursory -examination of applied voltage during drive, performed under T-227 periodically, indicated the nominal phase-to ground RMS voltage to be close to 105 volts. However, the failure to monitor and record voltage during test

< presents a significant limitation to data-interpretation, except where results are

" normalized".

14. When driving the mechanism in beyond the "in" ,

limit, a change in transient behavior does occur; continued shimming in the "in" direction exhibits characteristics of an "out" shim, while shimming out exhibits characteristics of an "in" shim (while the mechanism is still beyond the normal inserted position.).

Operations and Maintenance (0&M) Manual and FSAR References to shim motor wattage are made in the O&M Manual and FSAR, as indicated on Attachments 14 and 15.

No steady wattage outside the 80-110 watts for outward shims of normal rods has been observed, although. that i referenced by the O&M Manual is 72 watts. This might be consistent with references to an 18 watt increase being required to cause failure to scram, although there is another reference to 60 watts as the value at which failure to scram is possible (steady out wattage), at 105 volts, which is clearly inconsistent. Operational measurements, indicated nominal values of 90 watts, with the icwest values being 80 watts on a normally configured

CRDOA. It must be emphasized that all measurements

! collected were done without voltage monitoring or control, hence were subject to wide variation.

The FSAR also references 72 watts for normal outward shims, and 90 watts as the steady outward shim wattage beyond which scram capability cannot be assured.

The manner in which a wattage device is hooked up can 1 affect the output. The Fort St. Vrain devices have been carefully checked to verify that they are correctly  !

Procedure Logic Technical Services Procedure (TSP-30) allows measurement of wattage for monitoring purposes, as done in the past, with a clear guide for interpreting the results. This can be used to establish freedom of motion, estimate position from a kn wn position, and verify cable weight. These functions are useful for monitoring purposes during maintenance, trending, and monitoring performance in the PCRV under various operating conditions.

With regard to rod "in" position verification, TSP-30 uses a three-step approach which starts with the most easily identifiable (and obtainable) indication of rod full-insertion, prrgressing to a second more detailed evaluation if the requirements for the first evaluation are not met, and proceeds to a final, definitive test and evaluation if the first two simpler evaluations cannot meet the test basis requirements. Each step involves ,

repeated step performance so that postulated data collection irregularities should have an almost trivial chance of affecting the conclusion. Note that in the volumes of data reviewed, no da.. has been observed that would indicate invalidation of these tests.

Because of the repetition requirements, it is possible that ~ a given test performance would not meet the requirements for concluding the rod pair was inserted, even though a preponderance of data indicated that it was.

Failure to reach the requirements for certifying insertion does not mean that the rod is not inserted or that additional testing may not be done. In fact, the best approach to the test would be to perform the test, and if there was very marginal indication of insertion based on that step approach, continue on to the next, stronger version of the test. (If the results looked very good except that one data point was not distinct, repetition of that step should allow conclusive results).

Two major points should be made with regard to criticism voiced on these tests in the past. First, the acceptance criteria are now spelled out formally in terms of numerical values and guidelines based on data collected under T-214 on all Cit 00As. There are margins included here that in many instances would invalidate position conclusion from data runs on rods that were-known inserted at the time of collection (under T-214). Most data runs would however, allow the correct conclusion without repetition of that test step. Secondly, each test sequence repeats the sequence.

12

' This provides additional assurance that electrical system variations will not yield any transient which could be incorrectly taken to indicate inserted condition. In addition, note that all results are normalized, and absolute levels not used for acceptance criteria, again minimizing-any effects of electrical system variations. _

For the scrammed condition, for freely running rod pairs, the rods will be bottomed out. Each test sequence starts from this condition (scrammed), so that presumably the rods are bottomed. .

The first test approach merely shims the rod pair "out",

then "in", repeating twice, and looks for the dip in wattage on the "out" shim (after the peak) and the rise in wattage at the end of the "in" shim. If these location indicators are observed (within the numerical limits specified), the rods are considered "in".

This second test is based on results observed consistently under depressurized/ cooled-down conditions seen in T-214.

Its one weakness is that the initial dip is not quite so pronounced under other conditions, so that the requirements might not be met if the test were desired to be used under other conditions. Hence the second test.

This test consists of evaluating the inserted condition-again based on shimming "out" from the "in" position, but using the combination of wattage peaks and decay times to discern the difference between the first "out" shim and the subsequent "out" shim characteristics in the sequence of three shims. Again, these two aspects of behavior are easy to discern, and the test, although more complicated to evaluate, is still straightforward with respect to data collection. The possibility occurs, however, that the results will not allow a definite conclusion due to data spread, poor test conditions, or otherwise.

e

4 13

.The final test, and most definitive, is the worst to actually perform because it will almost certainly break the multijaws coupling, hence should only be used on a damaged mechanism with a damaged multijaws coupling (no analog / digital indication or inconsistent indication compared to in/out limit switches), with no "in" limit -

indication. This test involves scramming to establish "in" position (presumably), and then performing an "out"/"in" shim pair, which should approximately return the rod pair to its original "in" position, to establish reference shim values, for normal shims. An "in"/"out" sequence is then performed, which should drive the drum sheave beyond its normal limit, raising the rod pair on the drum in the reverse direction. Hence the characteristic is reversed. The "in" shim is actually lifting the rod pair, while the "out" shim is lowering it.

By observing this reversal "in" shim behavior, which is easily discernable so long as the drum wraps to a quarter turn (to develop the moment arm, where the wattage values l are nominally 90 watts to raise and 44 watts to lower),

the rod pair position is absolutely determined. Again, the sequence is repeated to confirm the behavior.

Finally, the question of the condition of the absorber pair, supported or not, can be addressed in part using data collected from an ICR0 (only one supported rod). The nominal wattage observed here was 60 watts for an "out" shim, compared to 90 watts for a normally configured rod

(range 80-110 watts for "out" shims). This suggests a limit of between 60 and 80 watts to determine the normal condition with both strings supported. In conjunction with trending, any sudden reduction in nominal steady "out" wattage could probably be used to confirm slack l

cable indication. A review of the slack cable shimming on Region 7 CRDOA SN 25 done July 20, 1984 indicated a steady wattage value of 76 watts (the same -CRDOA, SN 25, exhibited 88 watts on March 13, 1984 and 86 watts on June 25, 1984 for nominal out shim steady wattage), while installed in Region 14).

14 V. CONCLUSION The 'CRDOA wattage test is viable for monitoring motor, train, i and rod condition, can extract substantial information under a -)

variety of conditions, and can be used to establish rod pair inserted position. Additional testing should be done under more controlled conditions to confirm results obtained thus far and determine data spreads. Trending of this information should continue to monitor performance. Apparent discrepancies between FSV data and the FSAR and O&M Manual should be resolved and corrected.

Examination of a digital or other wattrecording device to increase the sensi tivity of the measurements should be considered, although may not be necessary if voltage variation is found to be the factor limiting test sensitivity. The test is entirely normalized with respect to test values so that absolute levels are not important.

1 EXPLANATION OF WATTAGE TEST EVALUATION SUPPORTING DATA This ' data was collected on either cf (2) Esterline Angus Model A 601C Graphic (recording) Wattmeters! rated at 100 volts and .1000- watts, full scale -(3 phase, 3 wird,160 Hz), serial numbers 182693,' 182699, calibrated July 7, 1984, with a.cuaranteed accuracy of 1% full scale

(10w). Precision, as' indicated by. peak and nominal values reached over many shims at approximately the same drum condition, appears to E.

i- be about: 1 watt. This means, provided voltage conditions are kept

. constant, tne readings can be compared between . shims on a given chart, so that very precise conditions can be achieved, which is important for the -use of the wattage test done here (Note -

variations in voltage over the time required to perform the test will generally not pose a problem, as these are typically slight). All 4

wattage values .are recorded assuming a precision of 1 watt. Also note that voltage variations have no effect on the watt recorder's

< ability to accurately determine wattage; rather, they change the

' mot 6r operating point so that power consumption, for the same load,

~

will be different. Finally, note that absolute determinations of ,

power in watts, for comparison against FSAR, O&M, and other values, are admittedly a problem because the test did not include voltage data; the proposed procedure corrects this problem. Consequently, these comparisons and any conclusions should be very tentative.

  • Remember the guaranteed accuracy is only 110w, even if the precision ,

is Iw. t

All-data values were recorded on a 0-500 scale where 500 corresponded to 1000w. Hence the reading in watts is that recorded timert two.

4 Also, the two wattmeters were adjusted for different chart speeds on +

the slow speed scale, as follows: t a

d SN 182698 (East Rx) 5 sec/ minor. division SN 182699 (West Rx) 2.5 sec/ minor division .

I Because the speeds for various charts were different, evaluation of overall mean decay times for reference purposes was intentionally not .I f done. This has no effect on the proposed test, as any given .

Individual CRDOA Shim Sequence Variation Analysis This !s the summary of detailed evaluation of shim sequences on individual CRDOAs to determine the variation in nominal values for out peak (drum wrapped), out' decay, in peak, and in decay. The purpose is to illustrate the mean and variation in these parameters, to allow comparison against the tested value, to examine the significance of the variation:

First Peak vs. Mean Peak First Decay vs. Mean Decay In shim data is again provided for information.

Note that -.10 shim sequences from 10 different mechanisms tested on various dates were selected. Selection was random, with the exception that several charts could not be used due to incomplete or

.awltiple shim activations during the transient periods, which

' required elimination because peak or other values could not be

,claarly' defined. The proposed test also eliminates this possibility by requiring complete repition of the sequence, should this occur.
