How will people learn if they need to take shelter or evacuate?
Persons located within about a ten-mile radius of a nuclear facility will be notified by means of sirens, tone-alert radios, and similar alert mechanisms. Persons living in the vicinity of a nuclear power plant must be advised annually regarding how they should respond and the procedures that they should follow. This is part of the licensee’s Emergency Preparedness Plan, which the NRC and the Federal Emergency Management Agency (FEMA) must review and approve.
