[VC Summer Nuclear Station] VCSNS received a report of siren actuation from a local resident at approximately 2340 EST. The EWSS indication at the Emergency Operations Facility showed siren #35 had actuated. A reset of the EWSS was performed. VCSNS is working to confirm actual siren activation and troubleshoot the issue. This event is still under investigation.

The investigation of this event has concluded that EWSS siren #35 did not actuate. This conclusion was reached after interviewing residents who reside directly across the street from EWSS Siren #35, who confirmed that this siren did not actuate. Also, maintenance personnel investigations concluded that the local activation indication was erroneous, due to observed battery readings being normal. Had the siren actuated, its batteries would have been depleted or nearly depleted.
