4.7 EMERGENCY POWER SYSTEM PERIODIC TESTS WO Applicability 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.

Specifications 4.7.1 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,anyloadedto 2400 + 100 kW.

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 nonnal and standby power sources and a simulated SIS signal.

Proper operations shall be verified by bus load shedding and automatic starting of selected motors a

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 750 amp at 2400 volts.

I i

e.

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

l 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 i

battery shall be measured and recorded.

b.

Every three months, the specific gravity of each cell, the temperature reading of every fifth cell, the height of electro-lyte, and the amount of water added shall be measured and recorded.

4.7.3 Emergency Lighting The correct functioning of the emergency lighting system outside of containment shall be verified at least once a year. The emergency lighting system inside containment shall be verified operable prior to each removal of the reactor head.

Basis The emergency power system provides power requirements for the engineered safety features in the event of a DBA. Each of the two diesel generators is capable of s equipmentfromindependentbuses.yp{yingminimumrequiredsafeguards This redundancy is a factor in establishing testing intervals. The monthly tests specified above will demonstrate operability and load capacity of the diesel generator. The fuel supply and various controls are continuously monitored and alarmed for abnormal conditions. Starting on complete loss of off-site power will be verified by simulated loss-of-power tests at approximately yearly intervals (during refueling shutdowns).

Considering system redundancy, the specified testing intervals for the station batteries should be adequate to detect and correct any malfunction before it can result in system malfunction. Batteries will deteriorate with time, but precipitous failure is extremely unlikely.

The surveillance specified is that which has been demonstrated over the years to provide an indication of a cell becoming unserviceable long before it fails. The emergency diesel generator limit of 750 amperes at 2400 volts corresponds to the manufacturer's nameplate kVA and kW rating of these machines.
