either of the startup transformers, backf eed through the main transformer, the 4160 volt line from the Vernon Hydroelectric Station or either of the two diesel generators. The backfeed through the noin transformer and 4160 volt Vernon line are both delayed access off-site power sourcen. Backfeeding through the main transformer can be accomplished by disconnecting the main generator f rom the main transf ormer and energizing the auxiliary transformer from the 345 kV switchyard through the main transformer. The time required to perform this disconnection is approxinately six hours.

Two 480 V Uninterruptible Power Systems supply power to the LPCIS valves via designated Motor Control Centers. The 480 V Uninterruptible Power Systems are redundant and independent of any on-site power sources.
This Specification assures that at least two off-site and two on-site power sources, and both 480 V Uninterruptible Power Systems will be available before the reactor is taken beyond *just critical' testing. In addition to assuring power source availability, all of the associated switchgear must be operable as specified to assure that the emergency cooling equipment can be operated, if required, from the power sources.
This Specification assures that at least two off-site and two on-site power sources, and both 480 V Uninterruptible Power Systems will be available before the reactor is taken beyond *just critical' testing.
Station service power is supplied to the station through either the unit auxiliary transf ormer or the startup transformers.     In order to start up the station, at least one startup transformer is required to supply the station auxiliary load. After the unit is synchronized to the system, the unit auxiliary transformer carries the station auxiliary load, except for the station cooling tower loads which are always supplied by one of the startup transformers.
In addition to assuring power source availability, all of the associated switchgear must be operable as specified to assure that the emergency cooling equipment can be operated, if required, from the power sources.
The station cooling tower leads are not required to perform an engineered safety feature function in the event of an accidents therefore. an alternate source of power is not essential.       Normally one startup transformer supplies 4160 volt Buses 1 and 3, and the other supplies Buses 2 and 4; however, the two startup transformers are designed with adequate capacity such that, should one become or be made inoperable, temporary connections can be made to supply the total station load (less the cooling towers) from the other startup transformer.
Station service power is supplied to the station through either the unit auxiliary transf ormer or the startup transformers.
A battery charger is supplied for each battery. In addition, the two 125 volt station batteries have a spare charger available.

The objective of this Specification is to assure that adequate power will be available to operate the emergency safeguards equipment.

Adequate powar can be provided by any one of the following sources:

Two 480 V Uninterruptible Power Systems supply power to the LPCIS valves via designated Motor Control Centers. The 480 V Uninterruptible Power Systems are redundant and independent of any on-site power sources.

This Specification assures that at least two off-site and two on-site power sources, and both 480 V Uninterruptible Power Systems will be available before the reactor is taken beyond *just critical' testing.

In addition to assuring power source availability, all of the associated switchgear must be operable as specified to assure that the emergency cooling equipment can be operated, if required, from the power sources.

Station service power is supplied to the station through either the unit auxiliary transf ormer or the startup transformers.

In order to start up the station, at least one startup transformer is required to supply the station auxiliary load.

After the unit is synchronized to the system, the unit auxiliary transformer carries the station auxiliary load, except for the station cooling tower loads which are always supplied by one of the startup transformers.

The station cooling tower leads are not required to perform an engineered safety feature function in the event of an accidents therefore. an alternate source of power is not essential.

The objective of this Specification is to assure that adequate power will be available to operate the emergency safeguards equipment.

1 Adequate power can be provided by any one of the following sources:

either of the startup transformers, backfeed through the main transformer, the 4160 volt line from the Vernon Hydroelectric l

Station or either of the two diesel generators.

The backfeed through the main cransformer and 4160 volt Vernon line are both delayed access off-site power sources.

Backfeeding through the main i

transformer can be accomplished by disconnecting the main generator from the main transformer and energizing the auxiliary transformer from the 345 kV switchyard through the main transformer.

The time required to perform this disconnection is approximately six hours, t

The 4160 volt line from the Vernon Hydroelectric Station can be connected to either of the two emergency buses within seconds by simple manual switching operation in the Main Control Room.

Two 480 V Uninterruptible power Systems supp)v power to the bpCIS valves via designated Motor Centrol Centers.

The 400 V Uninterruptible Power Systems are redundant and independent of any on-site power sources.

This Specification assures that at least two off site and two on-site power sources, and both 400 V Uninterruptible Power Systems will be available before the reactor is taken beyond "just critical" testing.

In addition to assuring power source availability, all of the associated switchgear must be operable as specified to assure that the emergency cooling equipment can be operated, if required, from the power sources.

Station service power is supplied to the station through either the unit auxiliary transformer or the startup transformers.

In order to start up the station, at least ene startup transformer is required to supply the station auxiliary load. After the unit is synchronized to the systern, the unit auxiliary transformer carries the station auxiliary load, except for the station cooling tower loads which arc always supplied by one of the startup transformers.

The station cooling tower loads are not required to perform an engineered safety feature function in the event of an accident; therefore, en alternate source of power is not essential. Normally one startup transformer supplies 4160 volt Buses 1 and 3, and the other supplies Buses 2 and 4; however, the two startup transformers are designed with adequate capacity such that, should one become or be made inoperable, temporary connections can be made to supply the total station.oad (less the cooling towers) from the other startup transformer.

A battery charger is supplied for each battery.

In addition, the l

two 125 volt station batteries have a spare charger available.

Power for the Reactor protection Slatem is supplied by 120 V ac motor generators with an alternate supply from MCC-8B.

Two redundant, Class 1E, seismically qualified power protection panels are connected in series-with each ac power source.

These panels provide overvoltage,.undervoltage, and underfrequency protection for the system.

Setpoints are chosen to be consistent with the input power requirements of the equipment connected to the bus.
