Callaway Emergency Communications and the Media 
If a radiological emergency occurs at the Callaway Energy Center, one of Ameren Missouri’s top priorities will be to provide timely, accurate information to the news media and allow media representatives to meet with and ask questions of Ameren Missouri personnel.
How The Media Will Be Notified
Ameren Missouri will provide initial notification of the emergency by fax or email to key media, including:

  • Mid-Missouri media
  • Wire services and the Missourinet
  • St. Louis media
We will also post media releases on

A radiological emergency at the Callaway Energy Center would be expected to generate an enormous amount of media interest. Therefore, our first priority will be to set up news briefings so large numbers of reporters can be accommodated and their questions answered at one central location.
In the early stages of an emergency, we recommend that the media not call the energy center or Ameren Missouri Communications personnel. Doing so will only delay our efforts to gather information and arrange news briefings to provide you with the most timely and accurate information possible!

How nuclear energy center emergencies are classified
Emergency action levels established by the Nuclear Regulatory Commission (NRC) come in four classes and are the same throughout the nuclear industry. They range from a minor energy center event involving no public danger to a more serious condition which might require protective actions for energy center employees and the general public. Each classification dictates a different response from county, state, and Ameren Missouri personnel.

  1. Unusual Event (minor) - Indicates a situation that is out of the ordinary and that could cause a reduction of safety at the energy center. Appropriate public officials and agencies are notified. No action is necessary for general employees or the public.
  2. Alert - Indicates events that most likely will affect the safety of the energy center to a minor degree. Public officials and agencies will be notified to go on standby. The energy center will mobilize its emergency response organization as a precautionary measure. There is no danger to the general public or energy center population and therefore no protective action is needed.
  3. Site Area Emergency - Indicates an event where actual or potential major failures of the energy center’s safety related equipment could cause radioactive releases to the atmosphere above the protective guidelines set by the Environmental Protection Agency (EPA) for radioactive releases. Local and state agencies activate their emergency operations centers and the emergency alert system is activated (sirens, tone alert radios, and reverse 911 telephone calls) to alert the public of the situation. Emergency alert system radio messages will broadcast on KTXY 106.9.
  4. General Emergency (major) - Indicates an event where safety conditions have deteriorated and significant releases of radioactive material beyond the energy center boundaries could occur. Local and state agencies begin necessary steps for public protection. Public alert systems are activated (sirens, tone alert radios, and reverse 911 automated call system). These messages provide the public with recommended protective actions.
