An emergency notification siren went off Thursday morning at the nuclear power plants in Scriba, but there was no emergency, officials say.
The siren was inadvertently tripped by a passing thunderstorm, possibly triggered by a lightning strike.
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 siren went off for longer than the three minutes they are designed to sound, and attempts to shut the siren down through the radio-based activation system were not successful.
This siren is only one of 37 that surround a 10 mile radius of the nuclear plants in Scriba.
