i APPLICABILITY BASES j
3.0.5 This specification delineates what additional conditions must be j
satisfied to permit operation to continue, consistent with the ACTION statements for power sources, when a normal or emergency power source is not OPERA 8LE.
It specifically prohibits operation when one division is inoperable because its normal or emergency power source is inoperable and a system, subsystem, train, component or device in another division 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 operation to be governed by the time limits of the ACTION j
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 that is determined to be inoper-1 able solely because of the inoperability of its normal or emergency power source.
For example, Specification 3.8.1.I requires in part that two emergency diesel generators be OPERABLE. The ACTION statement provides for a 7 day out-of -
l service time when one emergency diesel generator is not OPERABLE.
If the l
definition of OPERABLE were applied without consideration of Specification 3.0.5, all systems, subsystems, trains, components and devices supplied by the inoperable emergency power source would also be inoperable. This would dictate invoking the applicable ACTION statements for each of the applicable Limiting Conditions for Operation. However, the provisions of Specification 3.0.5 permit the time limits for continued operation to be consistent with the j
ACTION statement for the inoperable emergency diesel generator instead, provided the other specified conditions are satisfied.
In this case, this would mean that the corresponding normal power source must be OPERABLE, and all redundant systems, subsystems, trains, components, and devices must be OPERABLE, or otherwise satisfy Specification 3.0.5 (i.e., be capable of performing their i
design function and have at least one normal or one emergency power source l
OPERABLE).
If they are not satisfied, action is required in accordance with this specification.
As a further example, Specification 3.8.1.1 requires in part that two qualified I
circuits between the offsite transmission network and the onsite Class IE j
distribution system be OPERABLE. The ACTION statement provides a 24-hour out-of-service time when both required qualified circuits are not OPERABLE.
If the definition of OPERABLE were applied without consideration of Specification 3.0.5; all systems, subsystems, trains, components and devices supplied by the inoperable normal power sources, both of the qualified circuits, would also be inoperable. This would dictate invoking the applicable ACTION statements for each of the applicable LCOs. However, the provisions of Specifica-i tion 3.0.5 permit the time limits for continued operation to be consistent with the ACTION statement for the inoperable normal power sources instead, provided the i
