ELECTRICAL POWER SYSTEMS 3 4.8.3

'Alternative A.C. Power Sources Limitin Condition for 0 eration 3.8.3.1 The steady state bus 'voltage for the manual alternate reserve source*

shall be 90'A of the nominal bus voltage.

APPLICABILITY:

Whenever the manual alternate reserve source(69 kV) is connected'o more than two buses.

ACTION:

With bus voltage less than 90Ã nominal, adjust load on the remaining buses to maintain steady state bus voltage 90%

limit.

SURVEILLANCE RE UIREMENTS 4.8.3.1 No additional surveillance requirements other than those required by Speci ficati ons 4.8.1.1.1 and 4.8.1.2.

Verifying that a sample of diesel fuel from the fuel storage tank is within the acceptable limits specified in Table 1 of ASTH 0975-68 when checked for viscosity, water and sediment, 4.

Verifying the fuel transfer pump can be started from the control panel and transfers fuel from the storage system to the, day tank, 5.

Verifying the diesel starts from ambient condition, 6.

Verifying the generator is synchronized, loaded to

> 1750 kw, and operates for > 60 minutes, and 7.

Verifying the diesel generator is aligned to provide standby power to the associated emergency busses.

At least once per 18 months during shutdown by:

1.

Subjecting the diesel to an inspection in accordance with procedures prepared in conjunction with its manufac urer 's recommendations for this class of standby service, 2,

Verifying the generator capability to reject a load of >

600 kw without tripping, 3.

Simulating a loss of offsite power in conjunction with a safety injection signal, and:

a)

Verifying de-energization of the emergency busses and load shedding from the emergency busses.

b)

Verifying the diesel starts from ambient condition on the auto-start signal, energizes the emergency busses with permanently connected

loads, energizes the auto-connected emerqency loads through the load sequencer and operates for 5 minutes while its generator is loaded with the emergency loads.

c)

Verifying that on diesel generator trip, the loads are shed from the emergency buses and the diesel re-starts on the auto-start signal following manual resetting of the diesel trip lockout relay, the emergency buses are energized with permanently con-nected

loads, the auto-connected emergency loads are energized through the load sequencer and the diesel operates for + 5 minutes while its generator is loaded with the emergency loads.

8.

Verifying that on a simulated loss of the diesel gener-ator (with offsite power not available),

the loads are shed from the emergency busses and that subsequent loading of the diesel generator is in accordance with design requirements.

Simulating a loss of offsite power in conjunction with an ESF actuation test signaI, and a)

Verifying de-energization of the emergency busses and load shedding from the emergency busses.

Verifying the diesel starts from ambient condition on the auto-start signal, energizes the emergency busses with permanentIy connected

loads, energizes the auto-connected emergency (accident) loads through the load sequencer and operates for >

5 minutes uhile its generator is loaded with the emergency loads.

cP Verifying that on diesel. generator trip, the loads are shed from the emergency buses and the diesel re-starts on the auto-start signal following manual resetting of the diesel trip lockout relay, the emergency buses are energized with permanently connected

loads, the auto-connected emergency loads are energized through the load sequencer and the diesel operates for ) 5 minutes while its generator is loaded with the emerqency loads.

Verifying that all diesel generator trips, except engine overspeed and generator differential, are

'utomatically bypassed upon loss of voltage on the emergency bus and/or safety injection actuation signal.
