' 8. 3 Onsite Emergency Power Systems 8.3.1 AC Power System The ac onsite power system is a Class 1E system which serves as a standby to the offsite power system.

The safety function of the ac onsite emergency power system (assuming the offsite power system is not functioning) is to provide sufficient capacity and capability to ensure that the structures, I

systems, and components important to safety perform as intended.

The objec-

-i' tives of the staff review are to determine if the ac onsite emergency power system has the required redundancy, meets the single-failure criterion,'is testable, and has the capacity,~ capability, and reliability to supply power to all required safety loads in accordance with the requirements of GDC 5,17, i

and 18.

Ii The onsite ac power system consists of various auxiliary electrical systems designed to provide electric power to Class 1E and non-Class 1E station loads.

The standby ac power systems is an independent, onsite system designed to automatically start and provide adequate power for Class 1E loads to ensure

.l safe plant shutdown when preferred and alternate power sources are not available.

The Class 1E portion of the onsite power system is comprised of two redundant and independent 6.9-kV distribution systems with their 480-V load centers and i

0 motor control centers,118-V ac power system,125-V de system, and the standby power supplies (diesel generator units).

Onsite emergency power for each unit is supplied by two diesel generators.

Each diesel generator is automatically started by either a safety injection actuation signal or an emergency bus undervoltage signal on its respective 1-emergency bus.

Each diesel generator is capable of attaining rated voltage and frequency within 10 sec after receiving a starting signal. After obtaining rated voltage and frequency, the generators are connected automatically to their respective emergency buses.

Under accident conditions the safety loads will be connected in a precetenmined sequence to their respec,tive diesel generator. There is one diesel generator per bus.

Each diesel generator and 1

its associated equipment is located in a separate seismic Category I structure and is rated at 7000 W for continuous operation, and has a 2-hr rating of 7700 W.

The continuous rating exceeds the maximum predicted operating loads.

The applicant has documented tsat tests will be performed to demonstrate that during the loading sequence, the frequency and voltage are maintained above a level which would degrade the perfonaance of any load below einimum requirements.

The design and continuous rating are consistent with Regulatory Guide 1.9 and IEEE 387-1977 and, therefore, are acceptable.

Branch Technical Position ICSB 2 (PSB) (in Appendix 8A of the Standard Review Plan) requires that new and previously untried diesel generator designs to be used in nuclear testing program. power plant service undergo a prototype reliability verification The staff review indica".es that the diesel generators have successfully passed a prototype reliability veril'ication program of 300 valid start and load tests with no more than three allowed failures. This is in conformance with the staff position and is acceptable.

1; During the periodic testing of a diesel generator, if a safety-injection i

actuation signal occurs, the generator breaker will be tripped automatically by an "S" signal.

This permits the unit to be cleared from parallel operation with the system and enables the diesel generator to attain the emergency standby mode.

In this mode of operation, the diesel governor control changes automatically to the isochronous mode which maintains the engine running at a synchronous speed corresponding to 60 Hz at the generator terminals.

This is in full conformance with the staff position and is acceptable.

'i Page 38 of 42 The 118-V ac single phase, 60-Hz, grounded uninterruptible power is supplied to critical instrumentation and control circuits.

There are two static uninter-i ruptible power supplies (SUPS) for balance-of plant instrumentation and control systems, four uninterruptible power supplies (UPS) for the reactor protection system and one UPS for the plant computer.

Each SUPS consists of an inverter, ac input rectifier, bypass transformer, and static (automatic) and bypass (tanual) switches.

Each Class 1E inverter receives incoming normal power from a Class IE 480-V motor control center and backup de power from the Class 1E i

125-V battery by means of an suctioneering-type circuit.

If the ac power scurce fails, the inverter onstput will be mafs,tained without interruption: by the de power from the battery.

In the absence of inverter output, the static switch disconnects the inverter from the load and connects the load to the alternate supply line from the bypass (nonregulating) transformer within 1/4 cycle.

Each bypass transformer receives incoming power supply from a Class 1E 480-V MCC. The inverte.r will automatically resynchronize with the bypass source following restoration of this reference source.

A manual bypass transfer switch, provided for equipment maintenance, can be used to bypass the static switch and supply power to the load directly from the inverter or bypass

~

transformer.

Operation of the bypass switch to any position will not cause power interruption to the loaa., Bypassing of the static switch or inverter is annunciated locally and in the control room.

The ac instrument buses have two incoming circuit breakers to power the loads from either the SUPS or directly from the bypass transformers.

These manually cperated circuit breakers are mechanically interlocked to prevent paralleling

[

of sources.

t Based upon its review, the staff has determined that the four uninterruptible I

power supplies for the reactor protection systems are independent.

A Nuclear-safety related loads common to both units are powered from Class 1E MCCs and distribution panels which have supplies from each unit.

These dual unit supplies are interlocked to preclude supplying power to one MCC or distri-bution panel from both units simultaneously.

Incoming feeders to train A MCCs t 4 or distribution panels common to both units are supplied only from train A power systems of both units (a similar arrangement exists for train B equipment and incoming feeders).

This ensures the proper train separation between cquipment common to both units.

q t.il The applicant has applied the fo? lowing design criter9 to the Class IE r

equipment.

?

(1) All safety-related continuous-duty Class 1E motors are sized with a nameplate service factor of 1.15, except for some totally enclosed Cisss 1E motors that are sized for 115% of full load and have a 1.0 service factor.

(2) All safety-related Class 1E motors are designed to accelerate their i,.

driven loads with 80% of the motor-rated voltage available at the i

terminals.

Transformer impedances are selected to permit starting of the largest t

motor on the bus without exceeding a maximum voltage drop of'20% and at the saae time remaining within the interrupting and momratary capabilities of the breakers.

(4)

System grounding and equipment grounding are provided to reduce the electrical hazard to plant personnel.

The 6.9-kV system is low resistance grounded and is designed to trip on ground faults to protect the 6.9-kV equipment.

The diesel generator units are high-resistance grounded to allow the generator to continue to supply power without tripping on a single ground fault condition.

The 480-V system is high-resistance grounded with a ground detection scheme.

A ground fault condition on the 480-V system or in the diesel generator sys+am is annunciated in the control room.

'he above criteria are in conformance with Section 8.1 of this report and are ecceptable.

I As a result of its review of the emergency onsite ac power system, the staff.

has determined that there are no automatic transfers of loads or sources I

between redundant emergency buses, which is in accordance with Regulatory Guide 1.6.

Therefore, the staff finds 8.3.2 DC Power Systems The station de systems supply power to the plant instrumentation and control under all modes of plant operation.

In addition, upon loss of ac power, the de systems provide power for emergency lighting and turbine generator auxiliary motors.
