In An Emergency

View More Information

In the unlikely event of an emergency at the Duane Arnold Energy Center that requires you to take any action, you would be notified by the outdoor warning sirens and the emergency alert system. Outdoor warning sirens would sound throughout the entire 10-mile emergency planning zone.

  • When you become aware of an emergency, the best course of action is to monitor local radio or television stations for specific instructions.  While monitoring the situation, you should be preparing to either evacuate or shelter in place.
  • If you have questions about how to prepare or what to do, call United Way 2-1-1 or 1-866-469-2211 or from a cell phone 319-739-4211.
  • Take a moment to check-in with your neighbors to make sure they are aware of the situation. Please avoid using the telephone.
  • The 10-mile emergency planning zone has been divided into subareas. These subareas were established to help local officials provide clear evacuation and/or sheltering information for people in each subarea. If there were an emergency at the Duane Arnold Energy Center, it is unlikely everyone within the 10-mile radius would be affected. The area affected depends upon weather conditions, such as wind speed and direction and the severity of the situation.
  • Officials will broadcast up to the minute information during an emergency on local radio and television stations during all types of emergency events.
  • Hearing a siren or receiving an emergency alert does not necessarily mean you need to evacuate. Upon receiving an alert, go inside and monitor local radio and television stations for more information. The outdoor warning siren system is tested by local emergency management officials on the first Wednesday of every month. It starts at about 8:45 a.m. and tests both the public-address system as well as the steady and wail siren tones.
  • To supplement the warnings provided by the outdoor sirens and the emergency alert system, the public is encouraged to purchase a National Oceanic and Atmospheric Administration tone alert weather radio. These radios can provide valuable warning and information in any emergency.

Alerts and Warnings

View More Information

There are four emergency classifications at nuclear power plants. Each calls for a different level of response from plant and government personnel:

  • An Unusual Event is a minor incident such as severe weather and is the least serious of the four categories. Because of strict regulations, a number of events must be classified and reported as “unusual events” even though they pose no threat or danger to the public. Unusual Events do not require you to take any action.
  • An Alert is a minor incident that affects, or could potentially affect, reactor safety. There is the possibility of a small, limited release of radioactive material. It is rare for an Alert to require you to take any action. If action is needed, the emergency alert system will be used to notify you.
  • Site Area Emergency is a more serious incident such as a leak from the reactor coolant system. Radioactive releases are possible, but will not affect the areas beyond the plant property. If you need to take action, sirens will sound and the emergency alert system will be activated, alerting you to tune to local radio or television stations for official information.
  • General Emergency is the most severe emergency classification. Radioactive releases that could affect areas beyond plant property are possible. A major security event may also result in a general emergency. If you need to take action, sirens will sound, alerting you to tune to local radio or television stations for official information.

Sheltering In Place

View More Information

Sometimes, sheltering in place is the safest option. Sheltering in place means to remain where you are. If you are outdoors, immediately go into a nearby building.

If you are directed to shelter in place:

  • DO NOT pick up children at schools, preschools, or registered day care centers; emergency plans include special precautions for children in these facilities.
  • Tune to an official emergency alert radio station (600 AM or 96.5 FM), monitor the situation and prepare to follow additional directions from local officials.
  • If you have questions about how to prepare or what to do, call United Way 2-1-1 or 1-866-469-2211 or from a cell phone 319-739-4211.
  • Limit non-emergency phone calls. If you must use a mobile device, texting is preferred. This will help keep phone lines open.

If indoors:

  • Remain there until further notice.
  • Shut all windows and doors.
  • Turn off all ventilation (furnaces, fireplaces and air conditioners).
  • Cover open food containers.

If outdoors:

  • Go indoors immediately and follow the “if indoors” instructions.
  • Wash hands and face before eating and handling food.
  • Take a lukewarm shower, if possible.

If you are in your car, at work, or away from home:

  • Close car windows, vents, and shut off heating and cooling systems.
  • Turn your radio on to monitor the situation and follow directions.
  • If you are not home and your home is in an area being told to shelter in place, DO NOT try to go home. Leave the affected subarea(s) or enter a nearby building.
  • Stay where you are, monitor the situation and await further instructions.

Evacuation Information

Understanding nuclear energy

Nuclear power plants create steam to turn the blades of a turbine to generate electricity. Nuclear plants use uranium fuel in a process called nuclear fission. The fission reaction generates heat to create steam.

The uranium fuel inside the reactor is radioactive. It is securely contained and constantly monitored. The fuel is encased ceramic pellets which are stacked end-to-end inside long metal tubes. The tubes are assembled into fuel bundles that are immersed in water in the reactor core. The core is housed inside a nine-inch thick steel vessel. That vessel is inside a robust containment building made of steel-reinforced concrete.

Exposure to large amounts of radiation can be harmful to human health. However, given the nuclear industry’s strong commitment to safety, such exposures are extremely rare and unlikely.

Many monitoring devices placed in and around the Duane Arnold Energy Center can detect very small amounts of radiation. Plant operators are alerted if radiation amounts increase above the naturally occurring background levels. The operators then quickly notify state and county officials.

What is radiation?

Radiation is energy that is given off as a particle or wave. Radioactive elements are present naturally in small amounts throughout our environment. In the United States, natural sources, such as radon products, account for most of the radiation we are exposed to each year. Radiation also comes from medical tests such as X-rays, CT scans, and nuclear medicine studies. Normal everyday items such as smoke detectors also emit small amounts of radiation. Less than one percent of the radiation to which people are exposed comes from nuclear power plants.

If you have any questions or concerns about radiation, contact the Iowa Department of Public Health at (515) 281-3478.
