Oswego County Nuclear Power Plant Emergency Siren Test Scheduled for June 6

June 2, 2023

Constellation will perform a test of its public notification system on Tuesday, June 6 at approximately 1 p.m. During the test, 40 sirens in the 10-mile radius surrounding the nuclear plants in Scriba will sound for three minutes.

Additional single-siren tests may be conducted throughout the day. Constellation tests the siren system on a monthly and bi-annual basis to ensure public safety.

Because this is only a test, no response by the public is necessary. In an actual emergency, the sirens would sound to alert the public to tune in to a local Emergency Alert System (EAS) radio or television station for information. Current EAS stations and other important emergency planning information for residents, workers and visitors within 10 miles of a Constellation nuclear power plant is posted on our website: constellationemergencyplan.info.

The Nine Mile Point Nuclear Station is a dual‑unit nuclear power facility that can produce more than 1,676 megawatts of carbon‑free electricity – enough to power 1.2 million homes. The nearby 842‑megawatt James A. FitzPatrick Nuclear Power Plant generates carbon‑free electricity for 625,000 homes. The stations are located about seven miles northeast of Oswego and 50 miles north of Syracuse.
