What is the difference between Chernobyl and Three Mile Island?

Chernobyl was a design flaw-caused power excursion causing a steam explosion resulting in a graphite fire, uncontained, which lofted radioactive smoke high into the atmosphere; TMI was a slow, undetected leak that lowered the water level around the nuclear fuel, resulting in over a third of it shattering when refilled

How did they clean up Three Mile Island?

The cleanup at the Three Mile Island nuclear plant has ended after 14 years with a final puff of radioactive steam from the evaporator used to get rid of contaminated water from the 1979 accident. The steam, released at various times by the electric evaporator, carried tritium, a radioactive form of hydrogen.

Is 3 Mile Island still active?

Three Mile Island Generating Station Unit 1 (TMI Unit 1) permanently shut down on September 20, 2019, leaving a 45-year legacy of safe, reliable, carbon-free electricity generation and service to the community. It now enters a new era—the safe decommissioning and dismantlement of its components, systems and buildings.

Why is it called Three Mile Island?

Exelon says “TMI is so named because it is located three miles from Harrisburg International Airport.” The airport is in Londonderry Township, along the Susquehanna just upriver from Middletown. Someone apparently believed the island was about 3 miles long and people began calling it “ Three Mile Island .”

Is 3 Mile Island safe?

No immediate deaths or injuries were reported, and studies suggest that long-term physical health effects from the accident have been negligible, though this has been contested. What is clear is that the accident spurred sweeping safety regulations. The damaged reactor on Three Mile Island was never restarted.

Is Chernobyl still active today?

Early in the morning of April 26, 1986, the fourth reactor exploded at the Chernobyl nuclear power plant in Ukraine. 34 years later, Chernobyl radioactivity is still circulating. The long-lived radionuclides released by the accident mean the disaster continues decades on.

What is dangerous about nuclear power?

The Dangers of Nuclear Energy Meltdowns like the ones in Fukushima or Chernobyl released enormous amounts of radiation into the surrounding communities, forcing hundreds of thousands of people to evacuate. There is still no safe, reliable solution for dealing with the radioactive waste produced by nuclear plants .
