With one Unit 2 startup transformer (2A or 2B) inoperable and with a Unit 1 startup transformer (1A or 1B) connected to the same A or B
offsite power circuit and administratively available to both units, then should Unit 1 require the use of the startup transformer administratively available to both units, Unit 2 shall demonstrate the operability of the remaining A.C. sources by performing Surveillance Requirements 4.8.1.l.la.

SURVEILLANCE RE UIREMENTS 4.8.1.1.1 Each of the above required independent circuits between the offsite transmission network and the onsite Class lE distribution system shall be:
a.
Determined OPERABLE at least once per 7 days by verifying correct breaker alignments, indicated power availability; and b.
Demonstrated OPERABLE at least once per 18 months by transferring (manually and automatically) unit power supply from the normal circuit to the alternate circuit.
4.8.1.1.2 Each diesel generator shall be demonstrated OPERABLE:

Verifying the diesel starts from ambient condition and accelerates to approximately 900 rpm in less than or equal to 10 seconds**.
The generator voltage and frequency shall be 4160 + 420 volts and 60 + 1.2 Hz within 10 seconds after the start signal**.
The diesel generator shall be started for this test by using one of the following signals:
a)
Manual.
b)
Simulated loss-of-offsite power by itself.
c)
Simulated loss-of-offsite power in conjunction with an ESF actuation test signal.
d)
An ESF actuation test signal by itself.

Verifying the generator is synchronized, loaded*** to greater than or equal to 3685 kW in less than or equal to 60 seconds, and operates within a load band of 3450 to 3685 kM at least an additional 60 minutes, and 6.
Verifying the diesel generator is aligned to provide standby power to the associated emergency busses.

From the storage tank at least once per 31 days.
- The diesel generator start (10 sec) from ambient conditions shall be performed at least once per 184 days in these surveillance tests.
All other diesel generator starts for purposes of this surveillance testing may be preceded by an engine prelube period and may also include warmup procedures (e.g., gradual acceleration) as recommended by the manufacturer so that mechanical stress and wear on the diesel generator is minimized.
- Generator loading in less than or equal to 60 seconds shall be performed at least once every 184 days; timing for this loading test shall start upon the closing of the diesel genera'tor breaker.
All other loading for the purpose of this surveillance test may be performed according to manufacturer's recoomendations.
The indicated load band is meant as guidance to avoid routine overloading.
Variations in loads in excess of the band due to changing bus loads shall not invalidate this test.
