-4.7 EMERGENCY PO~ SYSTEM PERIODIC TESTS 4.7.1 Diesel Generators

a. Verify, each 31 days:

1) that each DG starts from standby conditions and achieves

~ 2000 V in ~ 10 seconds, steady state voltage ~ 2280 and

~ 2520 V, and frequency~ 59.5 and~ 61.2 Hz, and

2) that each DG operates for ~ 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />; for ~ 15 minutes loaded above the peak accident loading, and for the remainder of the test loaded ~ 2300 and ~ 2500 kW. Momentary transients outside the load range do not invalidate this test.

b. A test shall be conducted during each refueling outage to demonstrate the overall automatic operation of the emergency power system. The test shall be initiated by a simulated simultaneous loss of normal and standby power sources and a simulated SIS signal. Proper operations shall be verified by bus load shedding and automatic starting of selected motors and equipment to establish that restoration with emergency power has been accomplished within 30 seconds.

c. Each diesel generator shall be subjected to an inspection, in accordance with procedures prepared in conjunction with the manufacturer's recommendations for this class of standby service, at least once per refueling cycle during plant shutdown. The licensee shall utilize his best efforts to conduct additional major diesel generator inspections and overhauls during shutdown periods.

d. Verify, by analytical means, each 18 months that diesel generator steady state automatically connected electric loads do not exceed the continuous rating of 750 amp at 2400 volts.

e. The fuel transfer pumps shall be verified to be operable each month.

4.7.2 Station Batteries

a. Every month, the voltage of each cell (to the nearest 0.01 volt),

the specific gravity and the temperature of a pilot cell in each battery shall be measured and recorded.
