Arkansas Nuclear One Emergency Planning
This website is provided for your use in an emergency. While the information contained in this website is mainly for use should an emergency occur at Arkansas Nuclear One, much of the material may be useful in other emergencies such as chemical spills, tornados or floods. This information was prepared by the Arkansas Department of Health, Nuclear Planning and Response Program in conjunction with Entergy Operations, Inc. and officials of Conway, Johnson, Logan, Pope and Yell Counties.
What is an Emergency?
Many things could cause an emergency at a nuclear power plant. State and local officials will be told about any emergency that could cause the nuclear plant to become unsafe. There are four classes of emergencies at nuclear power plants:
Notification of Unusual Event: This is the least serious emergency class. It means that something out of the ordinary has happened. People living in the area should not have to take any action.
Alert: This class means plant safety could become a problem. State and local officials will go to their emergency centers to follow the situation. The general public should not have to take any action.
Site Area Emergency: This class means the public might be affected. You might hear the Emergency Siren Warning System. Tune into your local radio station for information. State and local officials will take action to protect those living in the area.
General Emergency: This is the most serious emergency class. State and local officials will take action to protect people in the area. Stay tuned to your local radio station for instructions.
RADIATION AND ITS EFFECTS
Radioactivity is the property possessed by some elements that spontaneously give off energy in the form of waves or particles. Radiation may be alpha, beta, or gamma.
• Alpha radiation is the least penetrating type. It can be stopped by a sheet of paper.
• Beta radiation is emitted from the nucleus of an atom during fission. It can be stopped by thick cardboard.
• Gamma radiation is electromagnetic waves emitted from a nucleus and is essentially the same as X-rays. It can be stopped by heavy shielding such as lead or concrete.
HEALTH EFFECTS
Radiation is a normal part of our everyday lives. It is used in medicine and dentistry for diagnosis and treatment in the form of X-rays and gamma rays. Naturally occurring radioactivity is found in the soil, water, air, and building materials. In Arkansas, the average radiation exposure from naturally occurring and man-made radiation is up to 180 millirem * per year. Most studies indicate that radiation exposure of up to several thousand millirem per year result in no measurable health effect.
In the event of an accidental release of radioactivity from Arkansas Nuclear One, Entergy Operations, Inc., state and local government emergency plans are designed to minimize the radiation exposure to the public. This is accomplished by the use of sheltering, staying indoors or evacuation as possible protective actions.
*This does not include the contribution of naturally occurring Radon gas, which is currently being studied.
HOW A NUCLEAR PLANT WORKS
The uranium fuel in a nuclear reactor produces heat. Primary coolant water circulates through the reactor and picks up heat as it flows around the nuclear fuel. The heated water is pumped into a steam generator where the primary coolant gives off heat to water in a separate secondary system before it is returned to the reactor to be heated again.
The secondary water in the steam generator is converted to steam which is routed to a turbine. The steam rotates the turbine which is connected to an electric generator.
After the steam leaves the turbine, it is condensed into water by passing over tubes containing cool lake water and is returned to the steam generator to be heated into steam again. The lake water that is used to condense the steam to water is warmed slightly. It is returned to the surface of the lake, where its heat is given up to the atmosphere. Unit 2 uses the cooling tower to dissipate excess heat in the form of water vapor from the condenser cycle.

What About Sheltering?
Sheltering means to stay indoors. Close all doors and windows. Turn off sources of outside air. Close the fireplace flue if not in use. Remain indoors until told it is safe to go out. Use the telephone only for medical, fire, or other extreme emergencies! If traveling in a vehicle, close windows, air vents, and put the air conditioner on the maximum setting if needed.
Always listen to your local radio station or Tone Alert radio for further instructions.
What About Staying Indoors?
Staying indoors is very similar to sheltering. However, there are some important differences. Because the mid-summer heat in Arkansas can often climb well above 100 degrees, closing off your home without air conditioning could present more of a health hazard than the one presented in a release at ANO. Therefore, staying indoors refers to just that, staying indoors but with your air conditioning or heat running to keep you cool in the summer or warm on a cold January day. The filters in your home’s heat and air system will also act to filter some of the radioactive particulates that might be in the air in your area because of a release at the nuclear plant. The Department of Health believes this to be a logical and safe alternative to sheltering during weather extremes such as heat or snow and ice.
IDrive Arkansas
IDrive Arkansas will show you the location of each construction zone on the state highway system. Activate the live traffic / traffic camera features for a clear understanding of how traffic is moving up to and through each construction zone. Add the weather radar feature and determine the impact storms are having on traffic moving through construction zones. https://idrivearkansas.com/
Evacuation Route Signs
Signs marking designated evacuation routes are in place along state highways. These indicate the direction to the Designated Reception Centers where you should report in the event of an evacuation resulting from an emergency involving Arkansas Nuclear One.
Family Preparedness
Your family may not be together when an emergency occurs, so it is important to have a family plan. Your plan should include how you will contact each other if you are separated during an emergency. For example, have each family member contact other family members who live outside the Emergency Planning Zone (EPZ). Everyone must know the name, address, and phone number of the contact. You may have trouble getting through, so be patient.
Have two predetermined locations outside the Emergency Planning Zone (EPZ) where your family can reunite, if separated.
For additional planning information, you may refer to www.ready.gov.
What About My Pets?
For reasons of health and safety, it is strongly recommended that pets not be brought to any reception center, however, it may be necessary under certain circumstances to do so. To facilitate the reasonable accommodation of domesticated animals, measures designed to assure a safe stay at the center are required. Domesticated pets are defined as dogs, cats, birds, rabbits, rodents or turtles or animals traditionally kept in the home for pleasure rather than for commercial purposes and can travel in commercial carriers, and be housed in temporary facilities. Reptiles (except turtles), livestock and animals classified as "vicious animals" will not be accepted.
While pets will not be allowed inside the actual reception center, limited facilities will be provided for the housing of your domesticated animals nearby. Animals should be transported in and remain housed in, portable containment devices while at the reception center pet facility. Care of these animals, such as providing food and water, will be the responsibility of the owner. Veterinary care needed by individual animals will have to be provided by the pet's owner. Liability for any harm or damage caused by the animal while at the reception center facility will also be the responsibility of the owner. Also, bringing your pets to the reception center will delay your entry to and processing from the reception center. It is believed that pets would not be put in any danger should they be left behind, especially if pet owners have areas in which they can house their pets, such as an enclosed garage. Whatever radiation to which they might be exposed is not believed to be great enough to cause any physical harm to them. Also, the lower radiation levels that would be expected to be emitted from an accident at ANO might take many years to manifest into any health problems and since most pets do not have a life expectancy exceeding this time frame, the likelihood of them suffering from an illness brought upon them by exposure to radiation from a possible release from ANO is remote. The shock and turmoil of uprooting these animals from their normal surroundings might actually prove more harmful to them.
'Service Animals' will be accepted at all Reception Centers, however, the owners will be responsible for care and control.
Radiological Information For Farmers And Gardeners
This information was prepared to answer questions that farmers and gardeners might have after a serious accident at Arkansas Nuclear One.
Radioactive material might be released from the nuclear plant to the environment during a serious accident. It could fall onto soil, grass, or surface water, and then be taken into the food chain by plants and animals.
To protect dairy animals, use uncontaminated water and feed supplies. Move dairy animals off pastures and into dry feed lots.
Safe water will be the most important need for animals--even more important than feed. Since you may be away from the livestock for at least 48 hours, provide a 48 hour emergency water supply in livestock shelter areas.
Protect other water supplies from contamination. Cover stock tanks with plastic sheeting or canvas. Water in an open pond would be contaminated and should not be used until shown to be safe. Feed stored in sheds or silos or under a canvas or plastic cover should be used instead of letting animals graze. Feed stored outside, such as hay, that cannot be covered in time can still be used if outer layers are removed.
Suspected contamination would mean that produce must be checked before consumed. In most cases, garden foods may be cleaned by a thorough washing with water. Roots and tubers are not affected by surface contamination.
If you have been instructed to evacuate your farm, you may be allowed to return to feed and care for your livestock. Permission to return to evacuated areas must be obtained through your County Emergency Operations Center and the State Technical Operations Control Director. More information is available from your County Agent's Disaster Handbook for Extension Agents, published by the United States Department of Agriculture or by calling the Arkansas Department of Health at 1-800-422- 6630 (toll-free) or (479)968-7171. TDD users may call 858-7890 or 1-800-633-6413 or 711 after normal hours.
HOW WILL I BE NOTIFIED?
Within 15 minutes of the time an emergency is declared at Arkansas Nuclear One, Entergy Operations, Inc. must notify state officials. State officials can then notify the public of an emergency within 15 minutes by use of the Emergency Warning System. You will hear a steady siren signal lasting about three (3) minutes. If you have a Tone Alert radio, it will be activated. STAY CALM! When you hear the sirens, listen to one of the local radio stations listed below or the Tone Alert radio for additional information.
Sirens are tested each Wednesday at noon, excluding holidays or when severe weather is present.
HOW DOES MY TONE ALERT RADIO WORK?
Persons within ten (10) miles of Arkansas Nuclear One are notified of an emergency by siren and Tone Alert radio. Persons who live in an area where there are no sirens, or are hearing impaired, or require special notification are provided with these receivers FREE of charge. The system is operated in cooperation with the National Weather Service. This system is tested every Wednesday between 11:00 a.m. and 12:00 noon. If inclement weather persists, then the testing will be performed the next clear day.
All Tone Alert radios issued by this office have a battery backup feature which allows the user to install a battery. This will allow the radio to work during a power outage. You may install a battery if you desire.
WHERE DO I GET ONE?

WHAT ABOUT MY TELEPHONE?
PLEASE avoid using the telephone, if possible. All lines should be kept clear for emergency calls. You should use your telephone only to report medical, fire, or other extreme emergencies. The warning sirens, local radio stations and Tone Alert radio are designed to keep you informed during an emergency.
SEVERE WEATHER PROTECTION
The siren system around Arkansas Nuclear One can also be used to alert the public of severe weather. This can be done by local officials if necessary. If a weather warning is issued, stay away from windows, doors, and outside walls. Go to the basement or interior of the house. You may want to get under something sturdy and cover your head. If you're in a mobile home or a car, it is safer to leave and find a sturdier structure. If no shelter is available, then lie flat in a ditch or ravine and cover your head. If a flash flood threatens, avoid areas that are subject to sudden flooding. Do not attempt to cross a flowing stream where water is above your knees. Do not attempt to drive over a flooded road since you could become stranded and trapped. If your vehicle stalls, abandon it immediately and seek higher ground. People often drown while trying to rescue their car.
What about Schools?
Because evacuation of school-age children is of the utmost importance, schools will be notified before the general public. Parents should not attempt to pick up their children at the schools since this will create a traffic problem that could cause a delay in the evacuation of the schools. The students will be taken to a reception center. Each school will be evacuated to a specific reception center. Once children are registered at the reception center, they may leave with a parent or legal guardian. If it is necessary, students will be monitored for radioactive contamination. To determine the reception center to which each school would evacuate, please see the chart below. All reception centers are located at schools.*
