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If the LCO Is met or is no longer applicable prior to expiration of the specified Completion Time(s), completion of the Required Action(s) Is not required, unless otherwise stated.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