LCO Applicability 1i1 3.0 3.0 LCO APPLICABILITY (continued)

I 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;
b. After performance of a risk assessment addressing inoperable systems and components, consideration of the results, determination of the acceptability of entering the MODE or other specified condition
  • in the Applicability, and establishment of risk management actions, if appropriate; exceptions to this Specification are stated in the individual Specifications, or
c. When an allowance is stated in the individual value, parameter, or

- 6ther Specification.

Tihis 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.

I LCO 3.0.5 Equipment removed from service or declared inoperable to comply with ACTIONS 1may be returned to service under administrative control solely to perform test4ing required to demonstrate its OPERABILITY or the OPERABILITY'of other-equipment, This is an exception to LCO 3.0.2 for the system retuirn>d to servicejundeo administrative control to perform the testing required to .demonstrateOPE.RABILITY.

LCO 3.0.6 When a supported sydtmLCOls not met solely due to a support system LCO not being met, the C6f.nditions and Required Actions associated with this supported system are noti required to be entered. Only the support system LCO ACTIONS are reiuired to be entered. This is an exception to LCO 3.0.2 for the supported system. In this event, an evaluation shall be performed in accordance with Specification 5.5.15, "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 saifety 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 systern, the applicable Conditions and Required Actions shall be entered in accordance with LCO 3.0.2.

When the Surveillance is performed within the delay period and the Surveillance is not met, the LCO must immediately be declared not met, and the applicable Condition(s) must be entered.

SR 3.0.4 Entry into a MODE or other specified condition in the Applicability of an LCO shall only be made when the LCO's Surveillances have been met within their specified Frequency, except as provided by SR 3.0.3. When an LCO is not met due to Surveillances not having been met, entry into a MODE or other specified condition in the Applicability shall only be made in accordance with LCO 3.0.4.

This provision shall not prevent entry into 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.
