Nuclear siren testing scheduled for Jan. 7 around Robinson Nuclear Plant
January 05, 2026Nuclear siren testing scheduled for Jan. 7 around Robinson Nuclear Plant
- Five- to 30-second quarterly test planned between 1 p.m. and 5 p.m.
- No public action required
HARTSVILLE, S.C. – Duke Energy and county officials will test the outdoor warning sirens around the Robinson Nuclear Plant between 1 p.m. and 5 p.m. on Wednesday, Jan. 7, 2026.
Why it matters: To ensure they are functioning properly, sirens will sound for five to 30 seconds. Anyone who hears a siren during scheduled testing does not need to take action.
- During testing, some sirens may be tested more than once. Follow-up testing after siren maintenance may be required after 5 p.m.
- Because this is a test, local broadcasting stations will not interrupt regular programming to broadcast EmergencyAlert System (EAS) messages. If there was a real emergency requiring the sirens to be sounded, local radio andtelevision stations would broadcast information to the public.
By the numbers: Duke Energy owns and maintains a network of sirens within 10 miles of each of its nuclear plants, including 59 sirens around the Robinson Nuclear Plant.
Emergency partners: Testing is performed in cooperation with emergency management officials in Chesterfield, Darlington and Lee counties, who are responsible for sounding the sirens.
