FULTON – One of the emergency notification sirens surrounding the nuclear power plants in Scriba inadvertently activated during a thunderstorm this morning, possibly as the result of a lightning strike. There is no emergency at the three nuclear power plants.
Dale A. Currier, director of the Oswego County Emergency Management Office, said siren repair personnel from Exelon Generation responded to the site in the town of Oswego as soon as they were notified the siren was sounding.
The cause for the malfunction is under investigation; however a thunderstorm was occurring at the time the siren began sounding and initial indications are that the siren was hit by lightning.
The malfunction caused the siren to sound longer than the three minutes they are designed to sound.
Attempts to silence the siren through the radio-based activation system failed.
The other sirens are functioning properly.
The siren is one of 37 located within a 10-mile radius of the nuclear power plants in Scriba. A system of sirens and tone-alert weather radios is in place to alert residents in the event of an emergency.
During an emergency at one of the plants that would require protective actions for the public, the sirens would be sounded for three minutes to alert residents of the area to turn their AM/FM radios or televisions to local Emergency Alert System (EAS) stations for further information and instructions.
EAS stations are listed in the Emergency Public Information Calendar mailed to residents of the Emergency Planning Zone surrounding the plants and in local telephone books.
