3.0.1 Limiting Conditions for Operation and ACTION requirements shall be applicable curing the OPERATIONAL MODES or other conditions specified for each specification.
3.0.2 Adherence to the requirements of the Limiting Condition for Operation and/or associated ACTICN vithin the specified time interval shall constitute ccapliance with the specification.
In the event the Limiting Condition for Operation is restored prior to expiration of the specified time interval, coepletion of the ACTION statement is not required.
3.0.3 Vhen a Limiting Condition for Operation is not met, except as provided in the associated ACTION requirements, action shall be initiated within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> to place the unit in a M0DE in which the Specifica1[on oes not apply y placing 1.

Vhere corrective measures are completed that permit operation under the ACTION caqtires nts, the ACTION say be taken in accordance with the specified time limits as measured from the time of failure to meet the Limiting condition for Operation.
Exceptions to these requirements are stated in the individual Specifications.
3.0.4 Entry into an OPERATIONAL MODE or other specified applicability condition shall not be made unless the conditions of the Limiting Condition for Operation are met without reliance on provisions contained in the ACTION statements unless otherwise excepted. This provision shall not prevent passage through OPERATIONAL MODES as required to comply vith ACTION statements.
3.0.5 vhan a systen, subsystaa, train, component or device is determined to be inoperabis solely because its emergency power source is inoperable, or solely because its normal power source is inoperable, it may be considered OPERABLE for the purpose of satisfying the requirements of its applicable Limiting Condition for Operation, provided: (1) its corresponding normal or emergency power source is OPERABLE and (2) all of its redundant systes(s), subsystea(s), train (s),

In this case. this would mean that for one division the emergency power source must be OPERA 8LE (as must be the components supplied by the emergency power source) and all renunaant systas, subsystems, trains, components and devices in the other division must be OPERABLE. or likewise satisfy Specification 3.0.5 (i.e., be capable of per-forming their design functions and have an amergency power source OPERABLE).
In other words, both emergency power sources must be OPERA 8LE and all reoundant systems, subsystems. trains. components and devices in both divisions }
must also be OPERABLE If these conettions are not satisfied, action is recutred in accordaner. with this. specification.
In MODES $ or 6. Spectficatton 3.0.5 is not applicable, ana thus the individual ACTION statments for eacn applicable Limiting Conettien for Operation in these MODES must be adhered to.
