Chernobyl Accident and Its Consequences

A Safety Comparison With the United States
Could a Chernobyl-type accident occur in the United States? A 2004 report by the National Academy of Sciences identified four key differences between the forces at play in the Chernobyl disaster and the U.S. nuclear energy program.
Safer Nuclear Plant Designs
All U.S. power reactors have extensive safety features to prevent large-scale accidents and radioactive releases. The Chernobyl reactor had no such features and was unstable at low power levels.
Stringent Emergency Preparedness Plans
Even with the Chernobyl reactor’s poor design, officials could have averted many radioactive exposures to the population with an effective emergency response. Key personnel at all U.S. power reactors work with surrounding populations on an ongoing basis to prepare for an orderly and speedy evacuation in the unlikely event of an accident.
Alert and Notification
Chernobyl plant operators concealed the accident from authorities and the local population and thus the government did not even begin limited evacuations until about 36 hours after the accident.
In the United States, nuclear power plant operators are required to alert local authorities and make recommendations for protecting the public within 15 minutes of identifying conditions that might lead to a significant release—even if such a release has not occurred.
The U.S. Nuclear Regulatory Commission posts resident inspectors at every nuclear power plant site to ensure the plants are following federal safety requirements.
Protecting the Food Chain
Since authorities did not promptly disclose details of the Chernobyl accident, many people unknowingly consumed contaminated milk and food. This would not be the case in the United States.
As it did following the Three Mile Island nuclear accident in 1979, the federal government would carefully monitor and test all food and water supplies that potentially could become contaminated. Under existing federal programs and regulations, the government would quarantine and remove from public consumption any unsafe food or water.
The accident at Three Mile Island caused the release of a small amount of radioactive material into the atmosphere, but it was too small to cause discernible health effects to the population living near the plant.
