Fjeii SHAFT REACTIVITY CONTROL SYSTEMS BASES BORATION SYSTEMS (Continued)

The boration flow path specification allows the RWST and the boric acid storage tank to be the boron sources.

Due to the lower boron concentration in the RWST, borating the RCS from this source is less effective than borating from the boric acid tank and additional time may be required to achieve the desired SHUTDOWN MARGIN required by ACTION statement restrictions.

The ACTION statement restrictions for the boration flow paths allow continued operation in mode 1 for a limited time period with either boration source flow path or the normal flow path to the RCS (via the regenerative heat exchanger) inoperable.

In this case, the plant capability to borate and charge into the RCS is limited and the potential operational impact of this limitation on mode 1 operation must be addressed.

With both the flow path from the boric acid tanks and the regenerative heat exchanger flow path inoperable, immediate initiation of action to go to COLD SHUTDOWN is required but no time is specified for the mode reduction due to the reduced plant capability with these flow paths inoperable.

Two charging pumps are required to be OPERABLE to ensure single functional capability in the event an assumed failure renders one of the pumps or power supplies inoperable.

Each bus supplying a pump can be fed from either a

e Emergency Diesel Generator or the offsite grid through a startup transformer.

The boration capability of either flow path is sufficient to provide the required SHUTDOWN MARGIN in accordance with Figure 3. 1-1 from expected qperating conditions after xenon decay and cooldown to 2004F.

The maximum expected boration capability requirement occurs at BOL from full power equilibrium xenon conditions and requires 3080 gallons of 20,000 PPM borated water from the boric acid storage tanks or 320,000 gallons of 1950 PPM borated water from the refueling water storage tank (RWST).

With the RCS temperature below 200'F, one boron injection source flow path is acceptable without single failure consideration on the basis of the stable reactivity condition of the reactor and the additional restrictions prohibiting CORE ALTERATIONS and positive reactivity changes in the event the single boron injection system source flow path becomes inoperable.

The boron capability required below 200'F is sufficient to provide a

SHUTDOWN MARGIN of 1X hk/k after xenon decay and cooldown from 200'F to 140 F.

This condition requires either 500 gallons of 20,000 ppm borated water from the boric acid storage tanks or 20,000 gallons of 1950 ppm borated water from the RWST.

More specifically, LCO's 3.5.2 and 3.8.2. 1 require that associated EDG's be OPERABLE in addition to requiring that Safety Injection pumps, battery chargers, and battery

banks, respectively also be OPERABLE.

This EDG requirement was placed in these particular LCO's due to the shared nature of these systems to ensure adequate EDG availability for the required components.

A situation could arise where a unit in MODES 1, 2, 3, or 4 could be in full compliance with LCO 3.8. 1. 1, yet be using shared equipment that could be impacted by taking an EDG out-of-service on the opposite unit.

In this situation, diesel generator ACTION 3.8. 1. I.d, which verifies redundant train OPERABILITY, may not be applicable to one of the units.

Thus, specific requirements for'EDG OPERABILITY have been added to the appropriate LCO's of the shared systems (3.5.2 and 3.8.2. 1).

It is important to note that in these particular LCO's the inoperability of the required EDG does not constitute inoperability of the other components required to be OPERABLE in the LCO.

Specific ACTION statements are included in 3.5.2 and 3.8.2. 1 for those situations where the required components are OPERABLE (by the definition of OPERABILITY) but not capable of being powered by an OPERABLE EDG.

Two emergency diesel generators (EDG) provide onsite emergency A; C. power for each unit.

EDG's 3A and 3B provide Unit 3 A-train, and B-train emergency power, respectively.

EDG's 4A and 4B provide Unit 4 A-train and B-train emergency power, respectively.

Due to the shared nature of numerous electrical components between Turkey Point Units 384, the inoperability of a component on an associated unit will often affect the operation of the opposite unit.

These shared electrical components consist primarily of both startup transformers, three out of four 4160 volt busses, and associated 480 volt motor control centers, all four 125 volt D.'C. busses, all eight 120 volt vital A. C. panels and eight out of twelve vital A.C. inverters,.four out of eight battery chargers, and all 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 a single unit is affected, the

This is to

~

allow the orderly shutdown of one unit at. a time and not jeopardize the stability of the electrical grid by imposing a dual unit shutdown.

As each startup transformer only provides the limited equivalent power of approximately 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.

The 30K RATED THERMAL 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 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.

The notification of a loss of startup transformer(s) to the NRC is not a 10 CFR 50.72/50.73 requirement and as such will be made for information purposes only to the NRC Operations Center via commercial lines.

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.

This requirement allows continued operation to be governed by the time limits of the ACTION statement associated with the inoperable diesel generator.

A footnote is added to ensure the remaining required EDG's are tested for OPERABILITY if one of the required EDG's becomes inoperable due to reasons other than preplanned preventative maintenance.

This statement will ensure that tests are performed to verify common mode failures do not exist.

When in Nodes 1, 2, 3 or 4, a unit depends on one EDG and its associated train of busses from the opposite unit in order to satisfy the single active failure criterion for safety injection (SI) pumps and other shared equipment required dur'ing a loss-of-coolant accident with a loss-of-offsite power.

Therefore, one EDG from the opposite unit is required to be OPERABLE along with the two EDG's associated with the applicable unit.

Revision 1, October 1979.

The OPERABILITY of 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.

As inoperability of numerous electrical components often affect the e

To satisfy the single failure criteria, when assuming a

loss-of-offsite power with the loss of an

EDG, an additional restriction is stipulated which requires each battery charger to have its associated diesel generator(s),

OPERABLE.

This requires both EDG's associated with a swing bus battery charger to be OPERABLE.

Provisions for requiring the OPERABILITY of the EDG associated with the battery charger is explicitly specified in the LCO.

This is because conditions exist where the affected unit would not enter the applicable ACTION statement in the LCO without this provision.

For example, with Unit 3 in.

MODE 1 and Unit 4 in MODE 5, the operability of both EDG 4A and 4B is not required.

One could postulate conditions where battery chargers 4Al, 3A2, 3B2, or 4B1 could be used to satisfy the LCO without having an associated OPERABLE EDG, unless specific provisions were made to preclude these conditions.

Verifying average electrolyte temperature above the minimum for which the battery was sized, total battery terminal voltage on float charge, connection resistance

values, and the performance of battery service and discharge tests ensure the effectiveness of the charging system, the ability to handle high discharge

rates, and verifies the battery capability to supply its required load.

Table 4.8-2 specifies the normal limits for each designated pilot cell and each connected cell for electrolyte level, float voltage, and specific gravity.

The limits for the designated pilot cell's float voltage and specific gravity, greater than 2.13 volts and not more than 0. 015 below the manufacturer's full charge specific gravity or a battery charger current that had stabilized at a low value, is characteristic of a charged cell with adequate capacity.

FINAI. DRAFT ELECTRICAL POWER SYSTEMS BASES Continued Operation with a battery cell's parameter outside the normal limit but within the allowable value specified in Table 4.8-2 is permitted for up to 7 days.

During this period:

(1) the allowable values for electrolyte level ensures no physical damage to the plates with an adequate electron transfer capability; (2) the allowable value for the average specific gravity of all the cells, not more than 0.020, below the manufacturer's recommended full charge specific gravity, ensures that the decrease in rating will be less than the safety margin provided in sizing; (3) the allowable value for an individual cell's specific gravity ensures that an individual cell's specific gravity will not be more than 0.040 below the manufacturer's full charge specific gravity and that the overall capability of the battery will be maintained within an acceptable limit; and (4) the allowable value for an individual cell's float voltage, greater than or equal to 2.07 volts, ensures the battery's capability to perform its design function.

The ACTION requirements specified for the inoperability of certain Motor Control Centers (MCC's),

Load Centers (LC's) and the 4160-Volt Busses provide restrictions upon continued facility operation commensurate with the level of degradation on each unit and the amount of time one could reasonably diagnose

. and correct a minor problem.

The level of degradation is based upon the types of equipment powered and the out-of-service limit imposed on that equipment by

~

the associated ACTION statement.

If this degradation affects the associated unit only, then no restriction is placed on the opposite unit and an out-of-service limit of 8 hours9.259259e-5 days 0.00222 hours 1.322751e-5 weeks 3.044e-6 months (except for MCC's 3A, 3K, 4J and 4K) is applied to the associated unit.

then an out-of-service limit of 8 hours9.259259e-5 days 0.00222 hours 1.322751e-5 weeks 3.044e-6 months is applied to the associated unit and an out-of-service limit based on the most restrictive ACTION requirement for the applicable shared or cross-unit load is applied to the opposite unit.

For example, if being used to satisfy 3.8.2.1, the Battery Chargers 3A2, 3B2, 4A2, and 4B2 are cross-unit loads and have out-of-service limits of 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months .

This is the most restrictive limit of the applicable equipment powered from MCC 3D and 40.

Therefore, an out-of-service limit of 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months is applied if the battery charger is required to be OPERABLE.

The ACTION requirements specified when an A.C. vital panel is not energized from an inverter connected to its associated D.C.

bus provides for two phases of restoration.

Expedient restoration of an A.C. panel is required due to the degradation of the Reactor Protection System and vital instrumentation.

The first phase requires reenergization of the A. C. vital panel within two hours.

During this'hase the panel may be powered by a Class lE constant voltage transformer (CVT) fed from a vital MCC.

However, the condition is permissible for only 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months as the second phase of the ACTION requires reenergization of the A.C. vital panel from an inverter connected to its associated D.C.

bus within 24'hours.

Failure to satisfy these

ACTIONS, results in a dual unit shutdown.

With one unit shut down one 4160-volt Bus on the associated unit can be deenergized for refueling outage maintenance.

The associated 480-Volt Load Centers can th n be cross-tied upon issuance of an engineering evaluation.
