5.6 EMERGENCY POWER SYSTEMS - SURVEILLANCE REQUIREMENTS Applicability Applies to the surveillance of the equipment supplying electrical power to the essential plant services.
Objective l
To establish the minimum frequency and type of surveillance for equipment supplying electric power to the plant auxiliaries to ensure that the motive power sources required to safely shut down the plant are available.
Specification SR 5.6.1 - Standby Diesel Generator Surveillance The surveillance of the standby diesel generators shall be as follows:
a)
Each standby generator set will be started and loaded to at least 50% of rated full load capacity once per week.
The test shall continue for at least two hours to enable the engine (s) and the generator to attain their normal operating temperatures.
b)
A loss of outside source of power and turbine trip shall be simulated to demonstrate that the standby generators and automatic controls are operable. This Surveillance Requirement shall be performed at least once per 6 months with a maximum allowable extension of 2 months per surveillance interval such that the maximum combined time interval for 3 consecutive surveillance intervals shall not exceed 20 months, c)
The diesel engine protection functions shall be calibrated annually.
d)
The diesel engine exhaust temperature " shutdown" and "declutch" shall be functionally tested monthly and calibrated annually.

'i e)
A loss of outside source of power and turbine trip shall be simulated at least once per refueling cycle, not to exceed eighteen (18) months, to demonstrate that the standby generators, automatic controls and load sequencers f
are operable. This surveillance may be performed in lieu of SR 5.6.1.b above.
l Basis for Specification SR 5.6.1 The purpose of the weekly test of the standby diesel generator is to exercise the engine by operating at design temperature and to demonstrate operating capability.
These tests will allow for detection of deterioration and failure of equipment.
The purpose of the loss of outside source of power and turbine trip test (SR 5.6.1.b), performed twice annually is to verify that the standby generator (s) are capable of starting automatically upon a simulated loss of outside power and turbine trip.
SR 5.6.1.e, performed at refueling intervals, verifies the same features as SR - 5.6.1.b but, additionally, verifies that the load sequencers automatically pick up required loads in the. event of a loss of voltage on the 480V essent.ial buses.
Speciff eation SR 5.6.2 - Station Etattery Surveillance The surveillance of the station and PPS batteries shall be as follows:
a) The specific gravity and voltage of the pilot cell and temperature of adjacent cells and overall battery voltage shall be measured every week.
b) The specific gravity and voltage to the nearest 0.01 volt, temperature of every fifth cell and height of electrolyte shall be measured every three months, c) The station and PP5 batteries shall be load-tested to
)
partial discharge once a year during plant shutdown.
j Basis for Specification SR 5.6.2 j
The type of battery surveillance called for in this specification has been demonstrated through experience to provide a reliable indication of a battery cell initial brerkdown well before it becomes unserviceable.
Since batteries will deteriorate with time, these periodic tests will avoid precipitious failure.
The manufacturer's recommendation for equalizing charge is vital to maintenance of the ampere-hour capacity of the battery.
As a check upon the effectiveness of this charge, each battery will be load tested to determine its ampere-hour capacity.
In addition, its voltage shall be monitored as a function of time. If a cell has deteriorated or if a connection is loose, tbs voltage under load will l
drop excessively, indicating need for replacement or maintenance.
