BASES SURVEILLANCE SR 3 8 1 2 and SR 3.8.1.7 (continued)

SR 3.8.1.7 recuires that, at a 184 day Frequency, the Division 1 anc 2 DGs start from standby onditions and achieves required voltage and frequency within 10 seconds.

Also, this SR requires that the Division 3 DG starts from l 109 D'

standby conditions and achieves a minimum required frequency within 10 seconds and required voltage and frequency within l 96'f 13 seconds. The start time requirements support the /O t assumptions in the design basis LOCA analysis (Ref. 5). The start time requirements are not applicable to SR 3.8.1.2 (see Note 3 of SR 3.8.1.2). Since SR 3.8.1.7 does require timed starts, it is more restrictive than SR 3.8.1.2, and it may be performed in lieu of SR 3.8.1.2. This procedure is the intent of Note 1 of SR 3.8.1.2. Similarly, the performance of SR 3.8.1.12 or SR 3.8.1.19 also satisfies the requirements of SR 3.8.1.2 and SR 3.8.1.7.

,a. e 3 P.1 1 Tiece! Eencrator f est Rhcdulc") is CE consistent with the industry guidelines for assessment of diesel generator perfon.r.ce (Ref.14). The 184 day Frequency for SR 3.8.1.7 is a redPtion in cold testing consistent with Generic Letter 84-15 (Ref. 7). These Frequencies provide adequate assurance of DG OPERABILITY, while minimizing degradation resulting from testing.

SR 3.8.1.3 This Surveillance demonstrates that the DGs are capable of synchronizing and accepting greater than or equal to the equivalent of the maximum expected accident loads. A minimum run time of 60 minutes is required to stabilize engine temperatures. while minimizing the time that the DG is connected to the offsite source.

Although no power factor requirements are established by this SR. the DG is normally operated at a power factor between 0.8 lagging and 1.0. The 0.8 value is the design rating of the mi ; hine, while 1.0 is an operational limitation to ensure circulating currents are minimized.

The load band for the Division 1 and 2 DGs is provided to avoid routine overloading of these DGs. While this Surveillance allows operation of the Division 1 and 2 DGs in the band of 5600 kW to 7000 kW. a range of 5600 kW to 96-5800 kW will normally be used in order to minimize wear on 109 (continued)

For the Division 3 DG, 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.
