- Full-volume, three-minute test scheduled between 10 and 11 a.m. on Wednesday, Oct. 8
- No public action required
SOUTHPORT, N.C. – The outdoor warning sirens around the Brunswick Nuclear Plant will be tested between 10 and 11 a.m. on Wednesday, Oct. 8, 2025. This is our annual, longer-duration test of up to three minutes.
The 38 sirens within 10 miles of the Brunswick Nuclear Plant will sound at full-volume for up to three minutes. To ensure they are functioning properly, it may be necessary to test some sirens more than once. Follow-up testing after siren maintenance may be required after 11 a.m.
Testing is performed in cooperation with emergency management officials in Brunswick and New Hanover counties, who are responsible for sounding the sirens.
Because this is a test, local broadcasting stations will not interrupt regular programming to broadcast Emergency Alert System (EAS) messages. If there was ever a real emergency at the plant requiring the sirens to be sounded, local radio and television stations would broadcast information and instructions to the public.
