- b. At least once per 92 days and within 7 days after a battery discharge with battery terminal voltage below 105 volts, or battery overcharge with battery terminal voltage above 145 volts, by verifying that:
- 1. The parameters in Table 4.8-2 meet the Category B limits, 2.. There is no visible corrosion at either terminals or connectors, or the connection resistance of these items is less than 150 x 10- ohms, and
- 3. The average electrolyte temperature of six connected cells is above 60~F.
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, and coated with anticorrosion material,
- 3. The resistance of each cell-to-cell and torminal 'connection is less than or equal to 150 x 10- ohms, and
- 4. The battery charger will supply at least 400 amperes for batteries A and B and 300 amperes for batteries C and 0 at 125 volts for at least 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />.
- d. At least once per 18 months, during shutdown, by verifying that the battery capacity is adequate to supply and maintain in OPERABLE status all of the actual or simulated emergency loads for the design duty cycle when the battery is subjected to a battery service test.
- e. At least once per 60 months, during shutdown, by verifying that the battery capacity is at least 80K of the manufacturer's rating when subjected to a performance discharge test. This performance discharge test may be performed in lieu of the battery service test required by Surveillance Requirement 4.8.2.1d.
Annual performance discharge tests of battery capacity shall be given to any battery that shows signs of degradation or has reached 85$ of the service life expected for the application. Oegradation is indicated when the battery capacity drops more than 10K of rated capacity from its average on previous performance tests, or is below 90K of the manufacturer's rating.

ELECTRICAL POMER SYSTEMS SURVEILLANCE RE UIREMENTS Continued (c) For each'ircuit breaker found inoperable during these functional tests, an additional representative sample of at least 10K of all the circuit breakers of the inoperable type shall also be functionally tested until no more failures are found or all circuit breakers of that type have been functionally tested.
- 2. By selecting and functionally testing a representative sample of at least 10K of each type of lower voltage circuit breakers.
Circuit breakers selected for functional testing shall be selected on a rotating basis. Testing of these circuit breakers shall consist of injecting a current with a value equal to 300K of the setpoint (pickup) of the long-time delay trip element and 150K of the setpoint (pickup) of the short-time delay trip element, and verifying that the circuit breaker operates within the time delay band width for that current specified by the manufacturer.
The instantaneous .element shall be tested by injecting a current for a frame size of 250 amps or less with tolerances of +40%/-25K and a frame size of 400 amps or greater of +25K and verifying that the circuit breaker trips instantaneously with no apparent time delay. Molded case circuit breaker testing shall also foll,ow this procedure except that generally no more than two trip elements, time delay and instantaneous, will be involved. Cir-cuit breakers found inoperable during functional testing shall be restored to OPERABLE status prior to resuming operation. For each circuit breaker found inoperable during these functional tests, an additional representative sample of at least 10K of all the circuit breakers of the inoperable type shall also be functionally tested until no more failures are found or all circuit breakers of that type have been functionally tested. +
- b. At least once per 60 months by subjecting each circuit breaker to an inspection and preventive maintenance in accordance with procedures prepared in conjunction with its manufacturer's recommendations.
