B. The detailed steps necessary for the Inservice Testing of those pumps listed in Enclosure 7.1 are contained in separate i Surveillance Test Procedures. Enclosure 7.1 lists the 4 Surveillance Test Procedures that are applicable to each Code Class pump.

C. 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. l 1

2. The reference points used to developor validate the l 2

curve will be measured using Instruments meeting or l exceeding the requirements of Section 5.3.

4. Construct the curve with onl those points beyond the

" flat" portion (Iow flow rates of the curves in a range which includes ore as is practicable as clos)y to design basis flow rates.

- 5. Vibration levels shall be validated for each reference point on the curve. If vibration levels vary significantly over the 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.

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

5.4.2 Frequency of Inservice Tests A. Normally - All quantities specified in the applicable  ;

Surveillance Test Procedure for each pump shall be measured '

or observed and recorded every 92 days during normal plant operation unless a more restrictive frequency is specified by  ;

during plant shutdown to minimize accumulation of
additional tests.

O PAGE80F14

GTP-301 REVISION 7 O C. Pumps in Regular Use ~

1. Pumps which are normally operated more frequently than every 3 months may be tested during normal operation without stopping the pump.
2. The Pump Data Sheets must show that each pump was operated at acceptable reference values in the required

' flow path and that the required quantitles specified in the STP were measured or observed, recorded, and analyzed on the applicable Pump Data Sheets.

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

5.4.4 Charging /SI Pumps - The Charging /SI Pumps (XPP0043A, XPP0043B, and XPP0043C) are tested in accordance with NRC Generic Letter 89-04, Position 9. This position allows the use of a I non- instrumented minimum flow path for quarterly testing with a test performed at substantial flow conditions during Cold Shutdowns or Refueling Outages. Quarterly testing on minimum flow in conjunction with testing at substantial flow conditions

.h V

during Refueling Outages provides adequate assurance that these pumps are capable of performing their design safety function upon demand.

5.4.5 Emergency Feedwater Pumps - The Emergency Feedwater Pumps (XPP0008, XPP0021 A and XPP0021B) are tested in accordance with NRC Generic Letter 89-04, Position 9.

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 transfernng 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)

,d 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)  ;

i Approval Status: Approved for use per SER dated 5-31-95 for a period of one year I from the date of the SER. Approval for use past the one year period is the based on the implementation of the measurement of Diesel Fuel Oil Transfer Pump discharge pressure and ,

comparing it to a reference value as required by OM-6,5.2.  ;

4 Basis for Relief: Flowmeters are not provided within the pump test circuits. The modifications required to install flowmeters would be very costly 4

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 tum, lir.iits the amount of time these pumps can be run

, without overflovMng the tank. Also, since the flow rate is

determined by rrcasuring the level change in the tank per unit I time and rotary screw positive displacement pumps are not i

, subject to the same flow oscillations as centrifugal pumps,  !

l observing the two minute hold time prior to taking pump data '

would not provide any benefit and would actually decrease the accuracy of the flow rate determination by limiting the sampling time for the data. l

GTP-301 ENCLOSURE 7.5 PAGE 2 OF 3 REVISION 7 O 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 01: 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

(* 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.

Class: 2 and 3 Function: N/A I Test Requirement: The resistance of the system shall be varied until the flow rate i equals the reference value. The pressure shall then be i determined and compared to its reference value. Altematively, j the flow rate can be varied until the pressure e uals the

- reference value and the flow rate shall be determ ed and

! compared to the reference flow rate value. (OM-6,5.2(b) )

Approval Status: Relief not granted per SER dated 5-31-95. If the use of pump curves becomes warranted in the future, a relief re uest snould

be written to include only those pumps for which te ing per the

! Code is impractical. Additionally, the seven elements discussed in NUREG-1482, Section 5.2 should be included in the relief request.

(

l 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 configurations to achieve arbitrary test conditions which may not reflect actual normal operating conditions. The use of individual pump curves will allow testing to occur at the point where the pump normally operates, also reducing the number of perturbations on the system.

Attemate Test: Individual mp 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 pump operability. The flow rate will be recorded and the dP will be verified to be within the acceptance limits for that flow rate. If 3

necessary, curves will be developed for vibration using the Alert and Required Action Ranges specified in OM-6, Table 3a.
