Diesel Generators (DG)

3 Function:
To transfer diesel f uel oil f rom the storage tank to the day tank.

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) Pressure (discharge) shall be determined and compared with corresponding reference values. (OM-6,5.2 (d) and Table 2) i
- 3) After pump conditions are as stable as the system permits, each pump shall be run at least 2 minutes prior to measuring l
required test parameters. (OM-6,5.6)
Basis for Relief:
Flowmeters are not provided within the pump test circuits. The modifications required to install flowmeters would be very costly O
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.
These positive displacement pumps discharge into a vented tank with no means provided to vary discharge pressure.
The i
discharge pressure of a positive displacement pump is directl,y proportional to the pressure of the system into which it is aum aing The system pressure in this instance is provided by the 1eac of the oil above the tank inlet. Therefore, the pump discharge pressure is low and virtually constant during pump operation and, in this case, is not a significant performance indicator.
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
'"'iing the two minute hold time prior to taking pump data'
-(J observ would not provide any benefit and would actually decrease the accuracy of the flowrate determination by limiting the sampling time for the data.

Test Requirement:
The resistance of the system shall be varit.

The pressure shall then be determined and com aared to its reference value. Alternatively, the flow rate can ae varied until the pressure equals the 1
reference value and the flow rate shall be determined and compared to the reference flow rate value. (OM-6,5.2(b))
j 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 (d'
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.
Alternate Test:
Individual pump curves, developed in accordance with Section 5.4.1.C and containing minimum and maximum AP Alert and Required Action Ranges, will be used to determine pump j
operability. The flow rate will be recorded and the AP will be verified to be within the acce atance limits for that flow rate. If necessary, curves will be deve oped for vibration using the Alert and Required Action Ranges specified in OM-6, Table 3a.

This attachment includes discussion pertaining to the reasoning, and provides justification for both inclusion or exclusion of pumps applicable to the requirements of GTP-301, " Inservice Testing of Pumps Second Ten Year interval". The intent of the pump selection basis is to provide a documented reference for responding to questions and concerns regarding the selection of components or lack thereof. The bases contained in this attachment will not completely avoid all inquiries, but by documenting the logic for decisions made, should minimize the amount of time and effort required to respond to those questions.
The basis also provides a means of documenting certain SCE&G positions where the code may be unclear and increase consistency of the testing performed.
