DieseL fueL is also availaoLe to the Unic 2 tank from four Jnic I :-C turbine fueL oil storage :anKs (Jni: I canks).

This additional storage is comprised of three :-C turbine fuel oil storage canks ac approximacely 23.900 gallons capacity each, and one r-C

urbine vertical light-off fuel oil storage :ank ac approximacely 23,900 gallons capacity, for a cotal Unit I fuel oil storage capacicy of approximately 95,600 gallons.

(The Unit I 7-C turbine horizontal Light-off fuel oil storage tank capacicy is not available to the Unit 2 tank.)

Connections are provided for fuel oil transfer from the four Unit ' canks to

.he Unit 2 tank. Therefore, the minimum diesel fuel oil inventory available to the diesel generators from the total on-site diesel fuel oil storage capacity is maintained at all times to assure :he operation of one diesel generator at its rated design capacity for seven days.

"Rated design caoacty" for this specification is defined as operation at 2500 kW for 22 hours2.546296e-4 days <br />0.00611 hours <br />3.637566e-5 weeks <br />8.371e-6 months <br /> and 2750 kW for 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> in any 24-hour period.

A supply of 19,000 gallons of fuel will ensure the ooerack:n of boct diesels carrying rated design capacity for ac Least 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> or cne diesel for at Leasc 96 hours0.00111 days <br />0.0267 hours <br />1.587302e-4 weeks <br />3.6528e-5 months <br />.

An additional 15.000 gallons wiLl be available to assure an adequate fuel supply tor at Least seven days of operation of a single diesel generator ac its raced design capacity.

Rated design capacity for Chis specificacion is defined as operation at 2500 kW for 22 hours2.546296e-4 days <br />0.00611 hours <br />3.637566e-5 weeks <br />8.371e-6 months <br /> and ac 2750 k4 for two hours in any 24-hour period.

Station batteries will deteriorate with time, but precipitous failure is extremely unlikely. The surveillance specified is chac which has been demonstrated over the years to provide an indication of a cell becoming unserviceable Long before it fails.

The equalizing charge, as recommended by the manuEaccurer, is vical to maintaining the ampere-hour capability of the battery.

As a check upon the effectiveness of the equalizing charge the battery shouLd be Loaded rather heavily and the voltage monitored as a function of time.

Experience has shown chat this tesc should be repeated at ntervals to detect deterioration of cells.(3)

If a ceLL has deteriorated or if a connection is Loose, the voltage under Loaa will crop excessively indicating ralacement or = :a enance.
