EN Revision Text: LOSS OF SIREN SYSTEM
The following information was provided by the licensee via email:
"On December 27, 2021, at 1014 EST, a system error in the site's Alert and Notification Siren System was identified, indicating a loss of the siren system affecting a greater than 25% of the emergency planning zone population. Review of the system's data logger indicates the system error has been present within the system since December 22, 2021, at 1245 EST.
"The fleet's telecommunications department has been contacted and is aware of the issue. In the event that a radiological emergency should occur at the Shearon Harris Nuclear Power Plant, Primary Route Alerting procedures will be put in use by the local jurisdictions.
"This condition is reportable as a Loss of Emergency Preparedness Capabilities per 10 CFR 50.72(b)(3)(xiii).
"The NRC Resident, state and local agencies have been notified."
* * * RETRACTION ON 12/29/21 AT 1630 EST FROM SARAH MCDANIEL TO KAREN COTTON * * *
The following information was provided by the Licensee via email:
"Further troubleshooting efforts identified that the Chatham County EOC Siren Activation Point remained capable of sending an alert signal to the sirens for the duration of the event described above. This ensures siren activation would be performed in a timely manner in the event of a radiological emergency. This Event Notification is therefore retracted, as no loss of emergency preparedness capabilities has occurred."
The NRC Resident and local agencies have been notified.

The licensee is a fixed radiography licensee and the source is exposed inside one of their main shops. The shop is not occupied, their [standard operating procedure] (SOP) is to have radiography work after hours when the work spaces are vacant. The area is secured by the radiographer/[assistant radiation safety officer] (ARSO) and his assistant. It appears the stand the guide tube was on fell [and] it is assumed the tube was damaged by the fallen stand. This is an initial report, more information will follow."
