1.0 INTRODUCTION
By letter dated June 4,1997, PECO Energy Company (the licensee) submitted a request for changes to the Peach Bottom Atomic Power Station (PBAPS), Unit Nos. 2 and 3, Technical specifications (TSs).
The requested changes would eliminate an inconsistency between emergency core cooling system (ECCS) operability requirements and the auto-start and protective trip bypass of the emergency diesel generators (EDGs) on an ECCS initiation signal during certain plant configurations.
Surveillance Requirement (SR) 3.8.2.1 will be annotated with a note which specifies +; hat the requirements for SR 3.8.1.12, SR 3.8.1.13, and SR 3.8.1.19 l are not required to be met when the associated ECCS is not required to be operable.
The Bases section for SR 3.8.2.1 will be revised to include the explanation for the note added to SR 3.8.2.1, and to indicate that the periods for which the ECCS sre not required are specified in Limiting Condition for Operation l
(LCO) 3.5.2, "ECCS - Shutdown."
2.0 EVALUATION Current TS 3.8.2, AC Sources - Shutdown requires two EDGs each capable of supporting one onsite Class 1E AC electrical power distribution subsystem be available during NODES 4, 5, and during movement of irradiated fuel assemblies in the secondary containment. As part of the compliance with this TS, SR 3.8.2.1 invokes the applicability of SR 3.8.1.12, SR 3.8.1.13, and l
SR 3.8.1.19 to ensure the operability of the EDGs in other than MODES 1,.2,
}
and 3.
SR 3.8.1.12 requires the verification that, on an actual or sian11ated l ECCS initiation signal, each EDG automatically starts from the standby condition.
SR 3.8.1.13 requires verification that certain EDG protective trips are bypassed on an actual or simulated ECCS signal.
