Duke Energy to Test Sirens Around Catawba Nuclear Station

GASTON COUNTY, N.C. – Duke Energy plans to test its outdoor warning sirens around the Catawba Nuclear Station on Wednesday, April 8 at 11:50 a.m. The 89 sirens within 10 miles of the station will sound for three minutes. The public does not need to take any action, as this test is performed in cooperation with emergency officials in Gaston, Mecklenburg, and York counties, who are responsible for sounding the sirens.

“With so many people working at home who aren’t normally there and the anxiety around coronavirus in our communities, we want to ensure folks understand this is a normal, regularly scheduled siren test and there is not an emergency at the plant,” said Sara Collins, the Senior Communications Consultant at the Catawba Nuclear Station.

The purpose of the sirens is to alert people who are outdoors to go inside and tune to a local radio or television station for additional information. Because this is only a test, local broadcasting stations will not interrupt regular programming to broadcast the Emergency Alert System (EAS) messages. However, in the event of a real emergency at the plant, the sirens would be sounded, and local radio and television stations would broadcast information and instructions to the public.

Full-volume siren tests are performed on the second Wednesday of each quarter between 10:00 a.m. and noon. The sirens at the Catawba, McGuire, and Oconee nuclear plants are tested for three minutes in January, April, and July.
