Helpful Information

  • There are several ways you could be notified of a problem at Catawba Nuclear Station:

    To alert people outdoors, county officials may sound sirens around the station. If you hear a siren, turn on your radio or television immediately. Tune to a local station that will carry an emergency information message. These stations will give you information and tell you what to do. HEARING A SIREN DOES NOT MEAN YOU SHOULD EVACUATE.

    To alert people indoors, radio and television stations will carry emergency information messages. Local fire, police and emergency officials may patrol affected areas within the EPZ broadcasting information via loudspeakers and/or go door to door to ensure residents are award of the situation. Follow their instructions. Stay tuned.

    Boaters also would be alerted. Officials will use any means necessary (e.g., boats, loudspeakers, etc.) to alert those on waterways and in recreational areas.

    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.

    In case of a problem, you will be provided specific instructions based on your location. Follow the instructions given on the radio or television.

  • Schools in the area around Catawba Nuclear Station have emergency plans for school children.

    In an emergency, school officials would be contacted by county emergency management officials.

    If an evacuation were ordered, all children attending school inside the 10-mile Emergency Planning Zone (EPZ) would be relocated to a designated pick-up facility for their school. This may be different from the reception center/shelters listed for the student’s home.

    Parents should pick up students at designated pick-up facilities only. Do not call or go to the schools. This will help avoid delays. All relocation schools/ pick-up facilities are more than 10 miles from the station.

    Your children will be cared for at the facility by school and county officials until you arrive. 

    It is important for parents to know in what zones their children's schools are located. To find out, locate the correct zone on the EPZ map (pdf, 190 KB) for your children's schools. Parents should familiarize themselves with the relocation schools/centers (pdf, 53 KB) for their children's schools.

    If your children are ever left home alone, make sure they know what to do in an emergency. Children should know their zone and be familiar with your family’s emergency plan.
