3.7 ELECTRICAL POWER SYSTEMS BASES 3.7.1 3.7.2 and 3.7.3 A.C. SOURCES D.C. SOURCES AND ONSITE POWER DISTRIBUTION The OPERABILITY of the A.C. and D.C. power sources and associated distribution systems during operation ensures that sufficient power will be available to supply the safety-related equipment required for: (1) the safe shutdown of the facility, and (2) the mitigation and control of accident conditions within the facility.

The ACTION requirements specified for the levels of degradation of the power sources provide restrictions upon continued facility operation commensurate with the level of degradation.

The OPERABILITY of the power sources is consistent with the initialcondition assumptions of the safety analyses and is based upon maintaining adequate onsite A.C. and D.C. power sources and associated distribution systems OPERABLE during accident conditions coincident with an assumed loss-of-offsite power and single failure of one onsite A.C.

source.

Two physically independent:

A.C. circuits exist between the offsite transmission network and the onsite Class 1E Distribution System of each unit by utilizing the following: (1) a total of eight transmission lines which lead to five separate transmission substations tie the Turkey Point Switchyard to the offsite power grid. (2) Two dual-winding startup transformers each provide 10096 of the A and B train 4160 volt power from the switchyard to its associated unit.

In addition, each startup transformer has the capability to supply backup power of the equivalent of one emergency diesel generator (approximately 2500 kW) to the opposite unit's A-train 4160 volt bus.

Two emergency diesel generators (EDG) provide onsite emergency A.C. power for both units.

EDG A provides A-train power for both Units 3 R 4 and EDG B in turn provides B-train power for both units.

Due to the shared nature of numerous electrical components between Turkey Point Units 3 and 4, the inoperability of a component on an associated unit. will often affect the operation of the opposite unit.

These electrical components consist primarily of both emergency diesel generators (EDG's), both startup transformers, four 4160 volt busses, most 480 volt motor control centers, four 125 volt D.C. busses, a particular five out of six battery chargers, and four battery banks.

Depending on the component(s) which is (are) determined inoperable, the resulting ACTION can range from the eventual shutdown of the opposite unit long after the associated unit has been shutdown (30 days) to an immediate shutdown of both units.

Therefore, ACTION times allow for an orderly sequential shutdown of both units when the inoperability of a

component(s) affects both units with equal severity.

When an ACTION statement requires a dual unit shutdown, the time to be in HOT STANDBY has been revised from 6 to 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months .

This is to allow the orderly shutdown of one unit at a time and not jeopardize the reliability of the electrical grid by imposing a dual unit shutdown.

SOURCES AND ONSITE POWER DISTRIBUTION Continued As each startup transformer only provides the limited equivalent power of one EDG to the opposite Units A-train 4160 volt bus, the allowable out-of-service time of 30 days has been applied before the opposite unit is required to be shutdown.

With both one startup transformer and one EDG inoperable, the unit with the inoperable transformer can continue to operate at full power for only 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months based on the loss of its associated startup transformer and one of the EDG's.

After 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months , if the unit with the inoperable start-up transformer is in MODE 1 it must reduce THERMAL POWER to 30% RATED POWER within the next 6 hours6.944444e-5 days 0.00167 hours 9.920635e-6 weeks 2.283e-6 months . The 30% RATED POWER limit was chosen because at this power level the decay heat and fission product production has been reduced and the operators are still able to maintain automatic control of the feedwater trains and other unit equipment.

At lower power levels the operators loose automatic control of the feedwater system and must use manual control with the feedwater bypass lines.

By not requiring a complete unit shutdown, the plant avoids a condition requiring natural circulation and avoids intentionally relying on engineered safety features for non-accident conditions.

If the unit with the inoperable start-up transformer is in MODES 2,3, or 4, then the unit will be required'to be cooled down in accordance with the time frames of specification 3.0.1.

The unit with the OPERABLE startup transformer is controlled by the limits for inoperability of the shared EDG.

With both start-up transformers inoperable, the unit(s) in MODE 1 are required to reduce THERMAL POWER to 30% RATED POWER within 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months .

By not requiring a complete unit shutdown, the plant avoids a condition requiring natural circulation cooldown and avoids intentionally relying on engineered safety features for non-accident conditions.

If the unit(s) with the inoperable start-up transformer is in MODES 2,3, or 4, then the unit willbe required to be cooled down in accordance with the time frames of specification 3.0.1.

If a unit returns its associated start-up transformer to OPERABLE status, then that unit may increase THERMAL POWER to 30% RATED POWER and both units enter ACTION a based on the time that the remaining inoperable start-up transformer was taken out of service.

When one diesel generator is inoperable, there is an additional ACTION requirement to verify that all required systems, subsystems, trains, components, and devices, that depend on the remaining OPERABLE diesel generator as a source of emergency power, are also OPERABLE.

This requirement is intended to provide assurance that a loss-of-offsite power event will not result in a complete loss of safety function of critical systems during the period one of the diesel generators is inoperable.

The term verify means to administratively check by examining logs or other information to determine if certain components are out-of-service for maintenance or other reasons.

It does not mean to perform the surveillance requirements needed to demonstrate the OPERABILITYof the component.

The notification of a loss of start-up transformer(s) to the NRC is to be performed through the resident NRC inspector.

The requirement for both units to reach HOT STANDBY within 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months upon loss of both diesel generators minimizes the possibility of transients while allowing the orderly shutdown of both units.

The OPERABILITYof the minimum specified A.C. and D.C. power sources and associated distribution systems during shutdown and refueling ensures that (1) the facility can be maintained in the shutdown or refueling condition for extended time periods, and (2) sufficient instrumentation and control capability is available for monitoring and maintaining the unit status.

In MODES 5 and 6, the specification for coolant loops requires at least 2 coolant loops to be OPERABLE.

To ensure that at least one coolant loop has a source of onsite AC power available, the shutdown specification for AC sources requires that the OPERABLE diesel generator be capable of supplying power to its associated OPERABLE 4160 volt bus.

This is so that during a loss of offsite power event at least one train of shutdown cooling will have a source of onsite AC power.

In addition to the above

actions, the Reactor Coolant System (RCS) must be depressurized and vented.

This is required because the pressurizer Power Operated Relief Valves (PORVs) may no longer bg OPERABLE to prevent overpressure in these MODES.

The minimum size of the vent ensures that overpressure can be adequately relieved without exceeding the RCS pressure/temperature limits.

During a unit shutdown the one required circuit between the offsite transmission network and the onsite Class IE Distribution System can consist of at least the associated unit startup transformer feeding one 4160 volt Bus A or B, the opposite unit's startup transformer feeding the associated unit's 4160 volt Bus A, or the associated unit's 4160 volt Bus A or B backfed through its main and auxiliary transformers with the main generator isolated.

As inoperability of numerous electrical components often affect the operation of the opposite unit, the applicability for the shutdown LIMITING CONDITION FOR OPERATION (LCO) for A.C. Sources, D.C.

The allowable out-of-service times for the battery chargers depicted in Table 3.7-1 are based on the following criteria:

1.

Battery chargers 3B, 4A and 4S are all required for the operation of both units.

EDG's A and B field flashing are powered by batteries 3A and 4B respectively.

With one of battery chargers 3B, 4A or 4S inoperable, a

single failure of Battery 3A or 4B could result in less than the minimum required number of battery chargers being OPERABLE.

Therefore, an allowable out-of-service time of 72 hours8.333333e-4 days 0.02 hours 1.190476e-4 weeks 2.7396e-5 months is applied due to the reliance on a particular EDG.

2.

With any two of battery chargers 3B, 4A and 4S, or with any two of battery chargers 3A, 4B and 3S, one D.C. bus is inoperable and the corresponding allowable out-of-service time of 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months is applied.

3.

With a total of three or more battery chargers inoperable, shutdown of both units is required after 1 hour1.157407e-5 days 2.777778e-4 hours 1.653439e-6 weeks 3.805e-7 months based on the loss of greater than or equal to one-half of the available battery chargers and one D.C. bus.

The ACTION requirements which concern the inoperability of certain Motor Control Centers (MCC's) and 4160 volt Busses are limited by the action requirements of certain equipment which receive power from them.

As MCC D is common between both Units 3 and 4, it has been given an aOowable out of service time of 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months to allow the performance of preplanned maintenance.

As MCC D automatically transfers from a normal power supply to a back-up power supply fed from the opposite train, allowable out-ofwervice times have been applied to the power supplies themselves based on their reliance on a specific EDG to provide the "only" power source for the MCC. Therefore, the normal and back-up power supplies for MCC D both have allowable out-of-service times of 72 hours8.333333e-4 days 0.02 hours 1.190476e-4 weeks 2.7396e-5 months (7 days for preplanned preventative maintenance) based on the reliance on the remaining power source (EDG A or B) to power the required two Emergency Containment Coolers (ECC's), two Emergency Containment Filters (ECF's) of each unit and one of the required battery chargers 4S.

Therefore, upon the loss of the normal power supply to the 3A MCC, the A EDG is not OPERABLE.

The ACTION statements for the 3A MCC are similar to those applied to an inoperable diesel generator.

With one unit shutdown the 4160 volt Busses on the associated unit are only permitted to be inoperable for up to 7 days, for periodic refueling outage maintenance, upon issuance of an engineering evaluation based on the single failure vulnerability of equipment powered by sources on the shutdown unit which is required for the opposite unit at power.

They also assure that the emergency generator system controls and the control systems for the safeguards equipment willfunction automatically in the event of a loss of normal power.

The EDG Surveillance testing requires that each EDG be started from normal conditions only once per 184 days with no additional warmup procedures.

Normal conditions in this instance are defined as the pre-start temperature and lube oil conditions each EDG normally experiences with the continuous use of prelube systems and immersion heaters.

Each unit, as a backup to the normal standby AC power supply, is capable of sequentially starting and supplying the power requirement of the required safety feature equipment.

Each willassume fullload within 60 seconds after the initialstarting signal. (1/2 X3).

The SURVEILLANCE REQUIREMENTS to demonstrate each Emergency Diesel Generator (EDG) OPERABLE requires that the aut~onnected loads to each EDG do not exceed 2750 kW.

This requirement can be demonstrated by following the ESF testing method where each unit is individually tested for two loading conditions (i.e., loads due to loss of offsite power (LOOP) and loads due to LOOP coincident with a Safety Injection (SI)).

The results of the test on one unit are then added arithmetically to the test on the other unit with a LOOP coincident with a Safety Injection (SI) for each EDG respectively.

The sum of the difference between these loads operated in the test mode and the actual expected loads (i.e., load differences due to pumps run in recirculation mode) are added to the test values for each EDG.

The sum of the two test condition loads on opposite units will be representative of the actual design basis auto-connect loads on each EDG.

The EDG 8-hour Surveillance test demonstrates each EDG's capability to power the maximum of all auto-connected and required manually loaded emergency shutdown load (2850 kW) followinga design basis accident, loss of offsite power (LOOP) and a single failure of one EDG.

The surveillance requirement for the full load rejection test requires the steady state voltage reading to be less than or equal to 4784 volts within 2 seconds following the load rejection.

The purpose of the subject surveillance is to verify the proper operation of the voltage regulator and overspeed circuits during a full load rejection.

Since the ability to measure instantaneous maximum transient voltage is dependent on the mechanical response of the measurement devices and not necessary reflective of actual regulator performance, the ability of the diesel generator to return to a steady state condition in a defined time period is a more accurate and useful measurement of the diesel generator's ability to properly regulate voltage during the performance of a fullload rejection test.
