2.1 If any Step is answered NO, then IMMEDIATELY INFORM the SRO Ops. Supervisor, INITIATE a LCOAR or EDMR per applicable Tech.
Specs., and document in the COMMENTS section. If only One qualified circuit between the offsite transmission network and the onsite Class IE AC Electrical Power Distribution System is OPERABLE, then PERFORM S023-3-3.23, Attachment for A.C. Sources Verification.
2.2 Sync Circuit Check
[SR 3.8.1.1]
- Perform a Sync Circuit check per S023-6-2, Section for Checking Sync Circuit Operation, and verify that ALL of the following breakers are SAT:.
(Circle N/A for any out of.service breaker.)

LCO 3.8.1 for the affected Unit and Declare the associated Train EDG INOPERABLE. The INOPERABLE EDG should not be placed in Maintenance Lockout as this would make the EDG unavailable for a real accident. The EDG is considered INOPERABLE because it may not fulfill its function to sync to the 1E bus for EDG Surveillance Runs or during recovery from Loss of Offsite Power event.
