I 4.7 EMERGENCY POWER SYSTEM PERIODIC TESTS 4.7.1 4.7.2 Applies to periodic testing and surveillance requirements of the emergency power system.
Objective To verify that the emergency power system will respond promptly and properly when required.
Specif !cations Diesel Generators
- a.
Each diesel generator shall be manually started each month and demonstrated to be ready for loading.within 10 seconds~ The signal initiated to start the diesel shall be varied from one test to another to verify that A and B starting circuits are operable.
The generator shall be synchronized from the control room, and loaded to 2400 +/- 100 kW.
- b.
A test shall be conducted during ea~h 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.* Diesel generator electric loads shall not be increased beyond the continuous rating of 2500 kW.
- e.
The fuel transfer pumps shall be verified to be operable each month.
.Station Batteries
- a.
Eachmonth, 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.
