LCO Applicability 3.0 3.0 LIMITING CONDITION FOR OPERATION (LCO) APPLICABILITY LCO 3.0.1 LCOs shall be met during the MODES or other specified conditions In the Applicability, except as provided in LCO 3.0.2 and LCO 3.0.7.

LCO 3.0.2 Upon discovery of a failure to meet an LCO, the Required Actions of the associated Conditions shall be met, except as provided in LCO 3.0.5 and LCO 3.0.6.

If the LCO Is met or is no longer applicable prior to expiration of the specified Completion Time(s), completion of the Required Action(s) Is not required, unless otherwise stated.

LCO 3.0.3 When an LCO Is not met and the associated ACTIONS are not met, an associated ACTION Is not provided, or if directed by the associated ACTIONS, the unit shall be placed In a MODE or other specified condition In which the LCO is not applicable. 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, as applicable, in:

Exceptions to this Specification are stated In the individual Specifications.

Where corrective measures are completed that permit operation In accordance with the LCO or ACTIONS, completion of the actions required by LCO 3.0.3 Is not required.

LCO 3.0.3 Is only applicable In MODES 1, 2, and 3.

LCO 3.0.4 When an LCO Is not met, entry Into a MODE or other specified condition In the Applicability shall only be made:

a. When the associated ACTIONS to be entered permit continued operation In the MODE or other specified condition In the Applicability for an unlimited period of time; (continued)

c. When an allowance Is stated in the Individual value, parameter, or other Specification.

This Specification shall not prevent changes in MODES or other specified conditions In the Applicability that are required to comply with ACTIONS or that are part of a shutdown of the unit.

LCO 3.0.5 Equipment removed from service or declared Inoperable to comply with ACTIONS may be returned to service under administrative control solely to perform testing required to demonstrate Its OPERABILITY or the OPERABILITY of other equipment. This Is an exception to LCO 3.0.2 for the system returned to service under administrative control to perform the testing required to demonstrate OPERABILITY.

LCO 3.0.6 When a supported system LCO Is not met solely due to a support system LCO not being met, the Conditions and Required Actions associated with this supported system are not required to be entered. Only the support system LCO ACTIONS are required to be entered. This Is an exception to LCO 3.0.2 for the supported system. In this event, additional evaluations and limitations may be required in accordance with Specification 5.5.11, Safety Function Determination Program (SFDP)." If a loss of safety function is determined to exist by this program, the appropriate Conditions and Required Actions of the LCO in which the loss of safety function exists are required to be entered.

When a support system's Required Action directs a supported system to be declared inoperable or directs entry Into Conditions and Required Actions for a supported system, the applicable Conditions and Required Actions shall be entered in accordance with LCO 3.0.2.
