Sirens are the primary outdoor warning system for alerting the public of an emergency. In the unlikely event of an emergency to the nuclear station, Duke Energy would immediately notify federal, state and local authorities. These authorities could activate pole-mounted sirens located throughout the station's 10-mile EPZ.
If you hear a loud, steady sound coming from one of the sirens around the nuclear station, tune to a local radio or TV station. These stations will carry an emergency alert information (EAS) message from local officials to give you information and instructions on what to do.
Remember, hearing a siren does not mean you should evacuate. It simply means to tune to a local radio or television station for information. If sirens are sounding and you do not see or hear a message on radio or television, contact your county's emergency management office.
Please note: Regularly scheduled siren testing takes place on Wednesdays. Additional testing may occur at other times as part of ongoing maintenance.
To alert people indoors, radio and television stations will carry emergency information messages from local officials. Follow their instructions. Stay tuned. Remember, outdoor sirens will not necessarily be heard inside homes or businesses.
In an emergency, fire, police and rescue units may also patrol the affected area and sound their sirens, if necessary. Boaters also would be alerted via sirens, loudspeakers, etc.
Upon hearing a siren or emergency message, we also encourage people living in the 10-mile emergency planning zones to check with their neighbors to ensure they are aware of the situations – especially neighbors who may have special needs.
Emergency Planning Zones
It's important to know which Emergency Planning Zone (EPZ) you are in, because this will help you understand where to go in the event of an emergency. Check the map for the nuclear plant in your area and locate the zones where you live, work and/or go to school. In the event of an emergency, officials will announce specific instructions for zones. If there was an emergency at the nuclear station, it is unlikely everyone within the 10-mile EPZ would be affected. The areas affected would depend on weather conditions and the nature of the emergency.
Evacuations Routes and Reception Centers/Shelters
Under certain circumstances, people in specific zones might be asked by emergency management officials to evacuate. If you need help during an evacuation, contact your county emergency office. It is important that you go to a designated center/shelter, even if you do not plan to stay there. If you are not instructed to evacuation, stay off the roads to ensure emergency personnel can readily respond.
Use the map below to find your emergency planning zone, reception center/evacuation shelter and suggested evacuation route. Evacuation routes and reception centers/evacuation shelters for each zone are listed in the following document.
