• Specification.15.3.0.C delineates additional conditions which must be satisfied to permit operation to continue, consistent with the Limiting l Cchcitit.rJ for Operatier stitsunts for power sources, when a nontal or emerger.cy power source is not operable, it specifically prohibits operation when one system, subsystem, train, component or device is inopersle because its nonnal or emergency power source .is inoperable and a redundant system,' subsystem, train, component or device is inoperable for another reason.

The provisions of this specification permit the action statements associated with individual systems, subsystems, trains, components, or devices to be consistent:

with the action statements of the associated electrical power source. It allows operatior te be governed by the time limits of the action statement associated

~with the Limiting Condition for Operation-for the normal or emergency power source, not the individual action statements for each system, subsystem, train, component or device determined to.be inoperable solely because of the inoper-ability of its normal or emergency power source.

For examp.le, Specification 15.3.7.B.1.e allows a 7 day out-of-service time .l for one: emergency diesel generator. If the definition of operable were applied

' without consideration of Specification 15.3.0.C., all systems, subsystems,

. trains ' components or devices supplied by the inoperable emergency power source wo'uld'also be inoperable. This would invoke the applicable action statements for

.each of the applicable LCO. .However, the provisions of Specification 15.3.0.C permit the. time limits for continued operation to be consistent with the state-unt for the inoperable emergency diesel generator instead, provided the other specifie{conditior.s are satisfied. In this case, the corresponding normal' power source.must be operable, anc all redundant systems.: subsystems, trains. -components,

,' and devices 'must be operable. or otherwise satisfy Specification 15.3.0.C (i.e.,

be' capable of performing their design function and have:at 1 east one normal or one emergency power source operable). If these conditions are not satisfied.

shutdown is required in accordance with Specification 15.3.0.A.
