| event text =  
At 2354 EST, on January 26, 2020, officials with the State Emergency Operations Center and Newberry County, SC were notified of an apparent inadvertent actuation of a single siren in the VC Summer Early Warning Siren System (EWSS). 
[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.
This is a non-emergency notification of other government agency.  This event is reportable in accordance with 10 CFR 50.72(b)(2)(xi).
The NRC Resident Inspector has been notified.
The Licensee notified state and local agencies.
* * * RETRACTION ON 1/29/2020 AT 1502 EST FROM HANK KIRKLAND TO ANDREW WAUGH * * *
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.
The NRC Resident Inspector has been notified. Notified R2DO (Baptist).
