RCIC SystemB 3.5.3BASESACTIONS A.1 and A.2(continued)

If the RCIC System is inoperable during MODE 1, or MODE 2 or 3with reactor steam dome pressure

> 150 psig, and the HPCI Systemis verified to be OPERABLE, the RCIC System must be restored toOPERABLE status within 14 days. In this condition, loss of the RCICSystem will not affect the overall plant capability to provide makeupinventory at high reactor pressure since the HPCI System is the onlyhigh pressure system assumed to function during a loss of coolantaccident (LOCA). OPERABILITY of HPCI is therefore verified within1 hour when the RCIC System is inoperable.

This may be performed as an administrative check, by examining logs or other information, todetermine if HPCI is out of service for maintenance or other reasons.It does not mean it is necessary to perform the Surveillances neededto demonstrate the OPERABILITY of the HPCI System. If theOPERABILITY of the HPCI System cannot be verified, however,Condition B must be immediately entered.

For non-LOCA events,RCIC (as opposed to H PCI) is the preferred source of makeup coolantbecause of its relatively small capacity, which allows easier control ofthe RPV water level. Therefore, a limited time is allowed to restorethe inoperable RCIC to OPERABLE status.The 14 day Completion Time is based on a reliability study (Ref. 3)that evaluated the impact on ECCS availability, assuming variouscomponents and subsystems were taken out of service.

The resultswere used to calculate the average availability of ECCS equipment needed to mitigate the consequences of a LOCA as a function ofallowed outage times (AOTs). Because of similar functions of HPCIand RCIC, the AOTs (i.e., Completion Times) determined for HPCIare also applied to RCIC.If the RCIC System cannot be restored to OPERABLE status withinoverall plant risk is Ithe associated Completion Time, or if the HPCI System is[minimized.

Actions mustcontinue until OPDRVs are suspended.

Required Action F.1 has been modified by a Note stating thatLCO 3.0.3 is not applicable.

If moving irradiated fuel assemblies while in MODE 4 or 5, LCO 3.0.3 would not specify any action. Ifmoving irradiated fuel assemblies while in MODE 1, 2, or 3, the fuelmovement is independent of reactor operations.

Therefore, in eithercase, inability to suspend movement of irradiated fuel assemblies would not be a sufficient reason to require a reactor shutdown.

HATCH UNIT 1 B 3.6-92 !7l INSERT -Bases 3.6.4.3 Condition ETherefore, the plant must be brought to a MODE in which overall plant risk is minimized.

Toachieve this status, the plant must be brought to at least MODE 3 within 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months .Remaining in the Applicability of the LCO is acceptable because the plant risk in MODE 3 issimilar to or lower than the risk in MODE 4 (Ref. 6) and because the time spent in MODE 3 toperform the necessary repairs to restore the system to OPERABLE status will be short.However, voluntary entry into MODE 4 may be made as it is also an acceptable low-risk state.Required Action E.1 is modified by a Note that states that LCO 3.0.4.a is not applicable whenentering MODE 3. This Note prohibits the use of LCO 3.0.4.a to enter MODE 3 during startupwith the LCO not met. However, there is no restriction on the use of LCO 3.0.4.b, if applicable, because LCO 3.0.4.b requires performance of a risk assessment addressing inoperable systems and components, consideration of the results, determination of the acceptability ofentering MODE 3, and establishment of risk management

LCO 3.0.4 isnot applicable to, and the Note does not preclude, changes in MODES or other specified conditions in the Applicability that are required to comply with ACTIONS or that are part of ashutdown of the unit.The allowed Completion Time is reasonable, based on operating experience, to reach therequired plant conditions from full power conditions in an orderly manner and withoutchallenging plant systems.

With both RHRSW subsystems inoperable for reasons other thanCondition B (e.g., both subsystems with inoperable flow paths, or onesubsystem with an inoperable pump and one subsystem with aninoperable flow path), the RHRSW System is not capable ofperforming its intended function.

At least one subsystem must berestored to OPERABLE status within 8 hours9.259259e-5 days 0.00222 hours 1.322751e-5 weeks 3.044e-6 months . The 8 hour9.259259e-5 days 0.00222 hours 1.322751e-5 weeks 3.044e-6 months Completion Time for restoring one RHRSW subsystem to OPERABLE status, isbased on the Completion Times provided for the RHR suppression pool cooling and spray functions.

The Required Action is modified by a Note indicating that theapplicable Conditions of LCO 3.4.7 be entered and Required Actionstaken if an inoperable RHRSW subsystem results in an inoperable RHR shutdown cooling subsystem.

This is an exception to LCO 3.0.6and ensures the proper actions are taken for these components.

To achieve thisstatus, the unit must be placed in at least MODE 3 within 12 hour1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months sand in MODE 4 within 36 hours4.166667e-4 days 0.01 hours 5.952381e-5 weeks 1.3698e-5 months .

This SR does not apply to valves that are locked, sealed, or otherwise secured in position, since these valves are verified to be in the correctposition prior to locking,

sealing, or securing.

A valve is also allowedto be in the nonaccident

position, and yet considered in the correctposition, provided it can be realigned to its accident position.

This isacceptable because the RHRSW System is a manually initiated system. This SR does not require any testing or valve manipulation; rather, it involves verification that those valves capable of being(continued)
