COOK - UNIT 1 3/4 8-14 Amendment No-86

3/4.8 ELECTRICAL POWER SYSTEMS BASES The OPERABILITY of the A.C. and D.C. power sources and associated distr'bution 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 minimum specified independent and redundant A.C. and D.C. power sources and distribution systems satisfy the requirements of General Design Criteria 17 of Appendix "A" to 10 CPR 50.

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

The OPERABILITY of the power sources are consistent with the initial condition assumptions of the accident analyses and are based upon maintaining at least one of each of the 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 the other onsite A.C. source.

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 facility status.

The train N station battery system provides an independent 250 volt DC.

power supply for power and control of the turbine driven auxiliary feedwater pump train.

The limiting conditions of operation for the train N battery are consistent with the requirements of the auxiliary feedwater system.

The surveillance requirements for the train N battery system are consistent with the requirements of the AB and CD station batteries.

The train N battery loads are derived from equipment in the turbine driven auxiliary feedwater pump train and battery sizing is consistent with the functional requirements of these components.

Simulated loads for battery tests are loads equivalent to measured actual loads.

b.

At least once per 92 days by verifying that:

1.

The voltage of each connected cell is + 2.10 volts under float charge and has not decreased more than 0.05 volts from the value observed during the original acceptance

test, and 2.

The specific gravity, corrected to 77 F and full 0

electrolyte level (fluid at the bottom of the maximum level indication mark), of each connected cell is 1.200 and has not decreased more than 0.03 from the value observed during the previous test, and 3.

The electrolyte level of each connected cell is between the top of the minimum level indication mark and the bottom of the maximum level indication mark.

c.

At least once per 18 months by verifying that:

1.

The cells, cell plates and battery racks show no visual indication of physical damage or abnormal deterioration.

2.

The cell-to-cell and terminal connections are clean, tight, free of corrosion and coated with anti-corrosion

material, 3.

The battery charger will supply at least 10 amperes at E 250 volts for at least 4 hours4.62963e-5 days 0.00111 hours 6.613757e-6 weeks 1.522e-6 months .

d.

At least once per 18 months, during shutdown (MODES 5 or 6), by verifying that the battery capacity is adequate to supply and maintain in OPERABLE status the emergency loads for the times specified in Table 4.8.2 with the battery charger disconnected.

The battery terminal voltage shall be maintained

+ 210 volts throughout the battery service test.

e.

At least once per 60 months, during shutdown (MODES 5 or 6), by verifying that the battery capacity is at least 80%

of the manufacturer's rating when subjected to a performance discharge test.

This performance discharge test shall be performed in place of the battery service test.

COOK - UNIT 2 3/4 8-Z3 Amendment No. 72

3/4.8 ELECTRICAL POWER SYSTEMS BASES 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 minimum specified independent and redundant A.C. and D.C. power sources and distribution systems satisfy the requirements of General Design Criteria 17 of Appendix "A" to 10 CFR 50.

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

The OPERABILITY of the power sources are consistent with the initial condition. assumptions of the accident analyses and are based upon maintaining at least one redundant set of 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 the other 'onsite A.C. source.

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 facility

'.status.

The train N station battery system provides an independent 250 volt DC.

power supply for power and control of the turbine driven auxiliary feedwater pump train.

The limiting conditions of operation for the train N battery are consistent with the requirements of the auxiliary feedwater system.

The surveillance requirements for the train N battery system are consistent with the requirements of the AB and CD station batteries.

The train N battery loads are derived from equipment in the turbine-driven auxiliary feedwater pump train and battery sizing is consistent with the functional requirements of these components.

Simulated loads for battery tests are loads equivalent to measured actual loads.
