About the NIC
The Nuclear Information Center (NIC) provides an insider’s look into nuclear energy. Written by experts from Duke Energy's nuclear fleet, NIC articles feature nuclear industry insights including the benefits of nuclear energy, community events, emergency planning, videos and more.
Duke Energy’s Nuclear Fleet
By reliably providing power 24 hours a day, nuclear energy is an important part of the energy mix necessary to meet electricity demand. And, with no carbon emissions, it will remain an important clean energy resource for the future. Learn more about how nuclear plants work.
Duke Energy operates 11 nuclear units at six sites in the Carolinas. The combined generating capability of these facilities is approximately 10,700 megawatts. Duke Energy’s nuclear fleet generates approximately half of the electricity provided to its customers in the Carolinas, with production costs among the lowest in the nation.

Nuclear Emergency Preparedness
We always expect our nuclear stations to operate safely, but in the unlikely event of a nuclear station emergency, we want you to be prepared. Duke Energy’s highly trained and experienced employees work closely with states and counties to develop and routinely practice plans for handling emergencies.
To keep the public informed, neighbors who live within 10 miles of the station receive emergency planning information annually in a calendar mailed to their homes. In the event of a nuclear emergency, the public would be advised to tune to a local emergency alert station for further instructions and information.
To alert people outdoors, county officials will sound sirens located within the 10-mile area Emergency Planning Zones (EPZ) around the station. If you hear a loud, steady sound coming from one of the sirens around the nuclear station and it is not a siren test day, tune to a local radio or TV station. Hearing a siren does not mean you should evacuate.
2018 Siren Test Dates
Sirens are tested regularly to ensure they are working correctly. The testing is part of normal maintenance and no public action is necessary. Low- and full-volume siren tests are scheduled to occur on Wednesday mornings to minimize inconvenience for plant neighbors. Full-volume tests, which last up to three minutes, are conducted to make sure each siren works properly.

Brunswick, Harris and Robinson Nuclear Plants
Please note that siren testing times vary by plant but typically occur late morning around Brunswick and Harris and mid-afternoon around Robinson.
