DC Sources Operating 3.8.4 SURVEILLANCE REQUIREMENTS continued SURVEILLANCE FREQUENCY SR 3.8.4.5 Verify battery connection resistance is 12 months

< 24.4 E-6 ohms for inter-cell connectors of the Division 1 and 2 batteries,

< 169 E-6 ohms for inter-cell connectors of the Division 3 battery, and < 20% above the resistance as measured during installation for inter-tier and inter-rack connectors.

SR 3.8.4.6 Verify each required battery charger 24 months supplies the required load for a 1.5 hours at.

a. a 126 V for the 125 V battery chargers; and

b. a 252 V for the 250 V battery charger.

SR 3.8.4.7 -NOTES

1. The modified performance discharge test in SR 3.8.4.8 may be performed in lieu of the service test in SR 3.8.4.7 once per 60 months.*

2. This Surveillance shall not be performed in MODE 1, 2, or 3.

However, credit may be taken for unplanned events that satisfy this SR.

Verify battery capacity is adequate to 24 months supply, and maintain in OPERABLE status, the required emergency loads for the design duty cycle when subjected to a battery service test.

(continued)

• Rote 1 is modified to allow the performance gscharge test in SR 3.8.4 8 to be performed in lieu of the

~

service test in SR 3.8.4.7 for Battery E-81-2 until SR 3.8.4.7 is performed during the R-14 refueling outage or a forced outage of sufficient duration to perform the service test and accomplish the necessary post test battery recovery actions.
