Tom Silko, (802) 258-4146, tsilko@entergy.com NUREG-1433, LCO 3.3.2.2 Required Action C.1 requires that THERMAL POWER be reduced to less than 25% RTP within 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />. This change adds a new Required Action and a corresponding Note to allow affected feedwater pumps and main turbine valve(s) to be removed from service. The change is necessary to allow components to be removed from service to fulfill the safety function without requiring a reduction in power to < 25% RTP. A similar Note is added to LCO 3.3.4.1 (EOC-RPT) (BWR/4 only)Required Action C.1 and LCO 3.3.4.2 (ATWS RPT) Required Action D.1 to provide the same clarification for when the associated Required Action is the appropriate Action.
This change is acceptable because it provides operational flexibility, which could prevent an unnecessary reduction in power to less than 25% RTP. For example, if the required instrument trip Function is degraded only to the point of rendering main feed pump(s) incapable of tripping on reactor vessel high water level, the affected main feed pump(s) and main turbine valve (s) can be removed from service (satisfying the safety function). In this condition, although the trip function is not considered OPERABLE, the safety function has been implemented and therefore, no additional compensatory actions are necessary. For LCO 3.3.4.1 (BWR/4 only) and LCO 3.3.4.2, the change is required to provide a consistent clarification of when the associated Required Actions are the appropriate Action.
The BWR/6 LCO 3.3.4.1 (EOC-RPT), Required Action C.1, is not modified because the Required Action is appropriate regardless of the source of the inoperability due to the MODE of Applicability of the LCO being exited by taking the recirculation pump(s) out of fast speed.

Final Resolution: Superceded by Revision TSTF Revision 1 Revision Status: Active Revision Proposed by: NRC Revision
Description:
There are only three instrumentation LCOs in NUREG-1433 which do not address the actuated devices. This revision inserts a Note over the associated Condition of each of these three LCOs (Feedwater and Main Turbine High Water Level Trip Instrumentation, ATWS-RPT Instrumentation, and EOC-RPT Instrumentation) to clarify the situations under which the associated Required Action would the be appropriate Action.
