AC Sources-0peratint' B 3.8.1 BASES SURVEILLANCE SR 3.8.1.2 REQUIREMENTS (continued)
This SR helps to ensure the availability of the standby electrical power supply to mitigate DBAs and transients and maintain the unit in a safe shutdown condition.
To minimize the wear on moving parts that do not get lubricated when the engine is not running, thir SR is modified by a Note to indicate that all DG starts for this Surveillance may be preceded by an engine prelube period and followed by a warmup period prior to loading.
For the purposes of this testing, the DGs are started from standby conditions. Standby conditions for a DG mean that the diesel engine coolant and oil are being continuously circulated and temperature is being maintained consistent with manufacturer recommendations for DG 11 and DG 12.
For DG 13, standby conditions mean that the lube oil is heated by the jacket water and continuously circulated through a portion of the system as recommended by the vendor.
Engine jacket water is heated by an immersion heater and circulates through the system by natural circulation.
SR 3.8.1.2 requires that the DG starts from standby conditiens and achieves required voltage and frequency within 10 seconds. The DG's ability to maintain the required voltage and frequency is tested by those SRs which require DG loading. The 10 second start requirement supports the assumptions in the design basis LOCA analysis (Ref. 5).
The DGs are started for this test by using one of the following signals: manual, simulated loss 7f offsite power by itself, simulated loss of offsite power in conjunction with an ESF actuation test signal, or an ESF actuation test signal by itself.
The 31 day Frequency for SR 3.8.1.2 is consistent with the industry guidelines for assessment of diesel generator performance (Ref. 14). The Frequency provides adequate assurance of DG OPERABILITY, while minimizing degradation resulting from testing.

REQUIREMENTS Although no power fsetor requirements are established by this SR, the DG is normally cperated at a power factor between 0.9 lagging and 1.0.
The 0.9 value is conservative with respect to the design rating of the machine, while 1.0 is an operational limitation to ensure circulating currents are minimized. The load band for DG 11 and 12 is provided to avoid routine overloading of the TDI DG.
Routino overloading may result in more frequent taardown inspections in accordance with vendor recommendations in order to maintain DG OPERABILITY.
The 31 day Frequency for this Surveillance is consistent l
with the industry guidelines for assestment of diesel generator performance (Ref. 14).
Nete 1 modifies this Surveillance to indicate that diesel engine runs for this St.rveillance may include gradual loading, as recommended by the manufacturer, so that mechanical stress and wear on the diesel engine are l
minimized.
Note 2 modifies this Surveillance by stating that momentary transients because of changing bus lomis do not invilidate this test.
Note 3 indicates that this Surveillance shall be conducted on only one DG at a time in order to avoid common cause l
failures that might result from offsite circuit or grid perturbations.
Note 4 stipulates a prerequisite requirement for performance of this SR. A successful DG start must precede this test to credit satisfactory performance.
SR 3.8.1.4 This SR provides verification that the level of fuel oil in the day tank is at or above the level at whleh fuel oil is automatically added. The level is expressed as an equivalent volums in gallons, and ensures adequate fuel oil for a minimum of 30 minutes of DG operation at the maximum expected post LOCA load.

REQUIREMENTS This SR is modified by a Note. The reason for the Note is to minimize wear on the DG during testing.
For the purpose of this testing, the DGs must be started from standby conditions, that is, with the engine coolant and oil continuously circulated and temperature maintained consistent with manufacturer recommendations for DG 11 and DG 12.
For DG 13, standby conditions mean that the lube oil is heated by the jacket water and continuously circulated through a portion of the system as recommended by the vendor.
