5.2.3 Establishing an Additional Set of Reference Values l

1 A. If it is necessary or desirable, for some reason other than stated in Step  !

5.2.2,to establish an additional set of reference values, an Inservice Test shall first be run at the conditions of the existing set of reference values and the results analyzed.

B. If the Inservice Test discussed above is satisfactory, a second inservice l Test run at the new reference conditions shall be performed as soon as practical.

C. The results of the inservice Test run at the new refererice conditions shall establish the additional set of reference values.

~

GTP-301 REVISION 7 D. Whenever an additional set of reference values is established,the reasons for doing so shall bejustified and documented on Attachment I,

" Pump Reference Value Change Justification". Additionally, the requirements of Step 5.2.1 apply.

5.2.4 Allowable Variance From Reference Values for Variable Resistance Systems .

A. Since it is difficult to adjust system flow or pump discharge pressure to -

an exact value, a variance (plus or minus) of less than or equal to 0.5% of the adjusted pump parameter is permitted and may be incorporated into the associated inservice test proced ure. eb A

B. Variances between 0.5% and 2.0% (plus or minus) are also permitted with the following requirements:

1. The allowable variance shall be recorded on Enclosure 7.2

2. If, upon establishing trends in data, the adjusted pump parameter varies such that the readings are outside the accuracy of the instrument,the variance must be adjustments made as necessary. justified and acceptance crite 5.3 Instrumentation 5.3.1 General Requirements A. All instruments used for Inservice Tests may have nominal Accuracy errors wit hin the following limits:

Development of Pump Curves

1. Curves will be developed, or manufacturers pump curves will be validated when the pumps are known to be operating acceptably.

2. The reference points used to develop or validate the curve will be

- measured using instruments meeting or exceeding the requirements of Section 5.3.

3. Construct each curve with a minimum of five points, though fewer points may be acceptable for a narrow range.

4. Construct the curve with only those points beyond the " flat" portion (Iow flow rates) of the curves in a range which includes or is as close as practicable to design basis flow rates.

5. Vibration levels shall be validated for each reference point on the curve. If vibration levels varysignificantly overthe range of pump conditions, a method for assigning appropriate vibration acceptance criteria shall be developed for those regions of the pump curve. This may include the establishment of additional points where variation in vibration exists.

7. Acceptance criteria based on the curves should not conflict with

• Technical Specifications or Final Safety Analysis Report operability..

criteria for flow rate and differential pressure for the affected pump.

8. The use of pump curves for acceptance criteria requires relief  ;

because the Code does not allow for testing using pump curves.  ;

5.4.2 Frequency ofInserviceTests  ;

A. All quantities specified in the applicable Surveillance Test i Normally Procedure for each pump shall be measured or observed and record; every 92 days during normal plant operation unless a more restrictive frequency is specified by Technical Specifications. .

Quarterly test frequency shall be maintained, if possible, during

1. i plant shutdown to minimize accumulation of ad ditional tests.

2. For a pump in a system declared inoperable or not required to be operable and testing is undesirable, the pump shall be tested I I

within three (3) months prior to placing the system in an operable status and the test schedule followed.

3. Pumps which can only be tested during plant operation shall be tested within one week following plant startup.

C. Pumps in Regular Use

1. Pumps which are normally operated more frequently than every 3 months ma the pump. y be tested dun,ng normal operation without stop

2. The Pump Data Sheets must show that each pump was operated I at acceptable reference values in the required flow path and that the required quantities specified in the STP were measured or  ;

observed, recorded, and analyzed on the applicable Pump Data Sheets.

5.4.3 Duration of Tests - After pump conditions are as stable as the system permits, each pump shall be run for at leasttwo minutes. At the end of that period at least one measurement or observation of the quantities specified in the STP shall be made and recorded on the Pump Data Sheets provided in the  ;

IST PUMP TEST RELIEF REQUEST A.1 REVISION 1 System: Diesel Generators (DG)

Pumps: XPP0004A, XPP0004B, XPP0141 A, and XPP0141B Class: 3 Function: These pumps are required to perform a safety function by transferring fuel oil from the storage tank to the day tank under the combined loading conditions listed in the design specification (DSP-607).

Test Requirement: 1) When measuring flow rate, use a rate or quantity meter installed in the pump test circuit. (OM-6,4.6.5)

~2) An inservice test shall be conducted with the pump operating at specified test reference conditions. The test parameters shown in Table 2 shall be determined and recorded. Where system resistance can not be varied, flow rate and pressure shall be determined and compared to their respective reference values. (OM-6,5.2 and Table 2)

.s .

3) After pump conditions are as stable as the system permits, each pump shall be run at least 2 minutes. At the end of this time at least one measurement or observation of each of the quantities required shall be made and recorded. (OM-6,5.6)

Approval 5tatus: Approved for use per SER dated 5-31-95 for a period of one year from the date of the SER. Approval for use past the one year period is the based on i the implementation of the measurement of Diesel Fuel Oil Transfer Pump discharge pressure and comparing it to a reference value as required by O M-6, 5.2.

Basis for Relief: Flowmeters are not provided within the pump . test circuits. The

- modifications required to install flowmeters would be very costly and would not provide a significant enhancement of the monitoring capability for pump degradation over the monitoring capability provided by measuring the level change in the tank per unit time.

The amount of space available in each D. G. Day Tank is limited which, in turn, limits the amount of time these pumps can be run without overflowing the tank. Also,since the flow rate is determined by measuring the level change in the tank per unit time and rotary screw positive displacement pumps are not subject to the same flow oscillations as centrifugal pumps, observing the two minute hold time arior to taking pump data would not provide any benefit and would actua ly decrease the accuracy of the flow rate determination by limiting the sampling time for the data.

GTP-301 ENCLOSURE 7.5

.~ PAGE 2 OF 7 REVISION 7 IST PUMP TEST RELIEF REQUEST A.1 REVISION 1(Continued)

Alternate Test: The flow rate will be determined by measuring the rate of level increase in the fuel oil day tank using appropriate level instrumentation. This rate of level increase shall then be converted to flow rate via calculations. The level instrument and calculation accuracy shall meet the requirements of Table 1 (I 2 %). This,in conjunction with discharge pressure and vibration measurement, shall be performed at least once every 92 days prior to or subsequent to engine operation. The data will be taken independent of the two minute hold time.

". Additionally,luded should beinc in the reiki request.

Basis for Relief: Adjusting either the resistance of the system or the flow rate to achieve a single point reference value necessitates changing normal system confice;ations to achieve arbitrary test conditions which may not reflect actuai normal operating conditions. The use of individual l) ump curves will allow testing to occur at the point where the pump norma lly operates, also reducing the number of perturbations on the system.

Alternate Test: Individual pump curves, developed in accordance with Section 5.4.1.C and containing minimum and maximum dP Alert and Required Action Ranges, will be used to determine aump operability. The flow rate will be recorded and the dP will be verifiec to be within the acceptance limits for that flow rate. if necessary, curves will be developed for vibration using the Alert and Required Action Ranges specified in OM-6, Table 3a.

IST PUMP TEST RELIEF REQUEST C.1 REVISION O 4- System: CVCS Pumps: .XPP0043A j Class: 2 2

Function: Normal Charging and High Head Safety injection Pump i Test . ,

Requirement: Per ASME/ ANSI Oma-1988, Part 6, Article 6.1 rec uires the following:

i- " If deviations fall within the alert range of Ta ale 3, the frequency of the

, testing specified in para. 5.1 shall be doubled until the cause of the L deviation is determined and the condition corrected."

l Approv'al Status: ' Approved for use until the 10th Refueling Outage when it will no longer j . be applicable.

j Basis for Relief: The Charging /SI Pum >s are tested in accordance with NRC Generic Letter 89-04, Position 9. T1is position allows the use of a non-instrumented minimum flow path for quarterly testing with a test performed at

' substantial flow conditions during cold shutdowns or refueling outages. 1 Quarterly testing on minimum flow in conjunction with testing at

substantial flow conditions during refueling outag,es provides adequate j assurance that these pumps are capable of performing their design safety l

function upon demand.

l- This position is incorporated into the VCSNS Inservice Testing (IST) t Program. Through the IST Program, the acceptance criteria applied to

! pump performance is established through ASME/ ANSI Oma-1988, Part 6.

4 Part 6 is structured to address actions to be taken when performing t cuarterly tests for components within systems capable of demonstrating

) their design function performance during power operation.

+ -

The actions prescribed for components with parameters in the Alert range i- do not accommodate components relying on cold shutdown plant mode to

! demonstrate their design performance parameters. During the Spring 1996 refueling outage, Charging Pump A indicated one vibration po, int

> (pump vertical outboard) to be in the Alert range. It was noted that the 4 test frequency was impacted but that the pump was still recognized as

! operable to the Code acceptance criteria. VCSNS initiated an evaFuation to

determine the cause of the deviation and establish corrective actions.

T The evaluation included a review of Charging Pump A data collected to

determine a viable cause and establish corrective actions that could be

pursued at power to improve the vibration condition.

Efforts to determine the cause included

) e Analysis of the vibration data spectrum

e Review of past maintenance history 4

l' e Review of trend data (in particular, vibration and motor bearing )

temperatures)

Based on a review of available data, it was determined that the vibration deviation most likely originated from a seal replacement activity performed in November 1995. - Probable cause was concluded to be misalignment during pump restoration.

At power corrective actions performed to alleviate vibration and confirm cause included:

~

e Measured and recorded pump parameters while on mini-flow to establish comparison parameters prior to maintenance.

e Performed alignment check; discovered that gearbox and motor were both out of alignment and that both had a "so<t-foot".

3 .

e Corrected " soft-foot" problems and performed laser alignment for I

< pump, gearbox and motor.

e Measured and recorded post-maintenance pump parameters for evaluation.

e Monitored pump performance for two weeks following maintenance

while in normal operation.

Review of testing performed (pre-maintenance and post-maintenance) i and monitored data indicated that the tem >erature difference between '

motor inboard and outboard bearings 1ad decreased significantly

(~28' FAT down to ~10' FAT) and that the inboard bearing temperature had dropped (~165 F down to ~145'F) while the outboard bearing temperature had risen approximately 2*F (~133*F up to 135*F). This indicates that the two motor bearings are more equally loaded and lessen any bearing contribution to the vibration condition. -

There were no significant changes in vibration levels from pre-maintenance testing to post-maintenance testing (mini-flow).- A correlation between miniflow test results and full flow conditions cannot be established. However, the review of monitored data did reveal that the affected pump aarameter (pump vertical outboard vibration) was less for miniflow than t1e recorded value for full flow measured during the Spring 1996 outage. This condition was not as expected. The manufacturer was contacted and, upon considering the data ar.o maintenance history for Charging Pump A, expressed the opinion tha. the hi the full flow test was most likely attributed ~ 1 misab,gh vibration du i

. informed SCE&G that vibration has been obsenved to be higher at full flow  ;

conditions than at recirculation flow or mir How for pumps of this type i and model.

The manufacturer concluded that the pump could perform its design

function because the vibration recorded during full flow testing was not i excessive. Further discussion provided recommended actions that will be i' performed at the next available opportunity including

i j e Torque check the pump outboard fasteners for looseness.

l e Recheck alignment,if necessary, after torque check.

! e _ Measure and record vibration under full flow.

I

. Furthermore, the data collected during the Spring 1996 outage for the full i flow test of Charging Pump A indicated that the pum outboard vertical i vibration was higher than at other points on the pump y several orders of l

amplitude. The vibration was in the direction of hi est stiffness with respect to mounting; indicating a potential resonance condition.

~

} ~ Natural frequency testing performed during normal plant operation following the Spring 1996 outage confirmed that the pump b operatina in a natural frequency region of the casing. The data indicated that a wide natural frequency band exists from 20 to 200 hertz. ' Additionally, it was noted that the running pump speed falls to the left side of this region and that, at the point where the pump runs relative to the natural frequency, there is a steep decreasing slope in the area of the exciting force in the region of the natural frequency. _ A natural frequency in tiie area of the-exciting force of running speed makes a resonance condition possible. The fact that the running speed of the pump falls to the left side, but within the natural frequency region, allows small speed changes to affect the resulting pump casing vibration levels.

Ireview of Charging Pump A speed shows that the pump runs at a slower speed during full load, full flow conditions compared to inservice testing (IST), miniflow testing. While operating in the natural frequency region, the result of a load changi,ng variable, such as vibration due to misalignment, may produce a significant change as a result of resonance.

Resonance is a condition affected by either mass or stiffness. Decreases in the stiffness of the machine may shift the natural frequency region to the left, increasing the possibility of a resonance condition. In this case only a small change in sti1 ness is required due to the left side position of the exciting force inside the natural frequency region. Stiffness changes may have occurred between full flow testmg performed in November 1994 and .

the full flow testing performed in April 1996.

In summary, SCE&G has determined that Charging Pump A is operating satisfactorily, is not susceptible to catastrophic failure, and can perform its design basis function. This conclusion is supported by the pump manufacturer. Therefore, the proposed alternative monthly on-line monitoring program is considered sufficient to assure that the pump continues to operate satisfactorily.

AlternateTest: Perform monthly on-line vibration monitoring and analysis at normal plant operating conditions to verify pump performance and identify any pump degradation until the 10th Refueling Outage when full flow testing can be performed. Full flow testin during the next refueling outage will confirm the suspected cause and ven that maintenance actions performed during the cycle corrected the con ition or will identify that further action is necessary.

These pumps are required to perform a safety function by transferring fuel oil from the storage tank to the day tank under the combined loading conditions listed in the design specification (DSP-607). The pump motors are powered by a safety class 1E supply. These pumps are not required to operate during a seismic event , but shall be capable of operating at full capacity and pressure after a seismic event. The FUEL OIL TRANSFER pumps receive a start / stoa signal from the day tank level switches.

. The day tank capacity is 550 gallons wh ch is sufficient for 90 minutes of engine operation. The fuel oil transfer pumps provide long term supply of fuel oil (7 days) lC to the engines, under full load condrtions.

ASME/ ANSI OM Part 61988a requires vibration, flowrate, and discharge pressure to be measured and recorded. Relief has been requested and granted for the following:

9 -

Acquiring IST data during pump testing independent of the two minute hold time.

Measure the change in day tank level per unit time in lieu of installing instrumentation to monitor flow directly provided the acceptance criteria for flow as specified in OM-6, Table 3b is used.

ASME/ ANSI OM. Part 6 1988a Article 4.6.4 Vibration Measurements, provides guidance for the location and number of vibration reference points for pumps. The Fuel Oil Transfer Pumps are rotary screw positive displacement pumps and as such are not described in Article 4.6.4.

With the implementation of REE 94-024M the following conflict occurred between the original reference point and the new reference point in that the vibration pad can not be placed on top of a mating surface that could affect pump assembly. The measurement point was therefore relocated to a point near the pump center vertical C position. The vibration spectra of each pump was evaluated for differences at the old IST location and the new point. Information collected in the old location was taken with a stinger since a pad could could not be located at this point while the new point was taken with the magnet as intended. The comparison of each spectra, original vs new point, showed a large difference in the overall amplitude of each point as a result of low end integration error. The low frequency vibration error is a result of utilizing the stinger. The frequency content of each spectra are otherwise similar with comparable amplitudes.
