In 1979 at Three Mile Island nuclear power plant in USA a cooling malfunction caused part of the core to melt in the #2 reactor. The TMI-2 reactor was destroyed. Some radioactive gas was released a couple of days after the accident, but not enough to cause any dose above background levels to local residents.In 1979 at Three Mile Island nuclear power plant in USA a cooling malfunction caused part of the core to melt in the #2 reactor.

What happened to cause the Three Mile Island accident?
The accident at Three Mile Island 2 (TMI 2) in 1979 was caused by a combination of equipment failure and the inability of plant operators to understand the reactor's condition at certain times during the event.
Is 3 Mile Island still radioactive?
The fuel from Unit 2 was removed following its partial meltdown but an unknown level of contamination remains. “No matter how you cut it, Three Mile Island is a radioactive site indefinitely,” said Eric Epstein, an activist who's followed the site's legacy for four decades.
Can you go to 3 Mile Island?
Is the Three Mile Island Nuclear Accident Site Safe Today? It is completely safe to visit (or live) in the area, today. In 1979, the plant leaked radioactive iodine 131 gases.
Who owned Three Mile Island?
Exelon Generation, LLC The Three Mile Island Nuclear Station Unit 1 (TMI-1) was a 2,568 MWt pressurized water reactor that began operation in 1974 and is owned by Exelon Generation, LLC.
Does anyone live on Three Mile Island?
The Three Mile Island Incident Three Mile Island is just outside of Harrisburg, a place where many people still move today. Over thirty years ago, both human and mechanical errors brought on a partial meltdown in one of the reactors at the plant. Dangerous radioactive gases were released into the atmosphere.
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.

Why was Three Mile decommissioned?
TMI-2 Solutions acquired the reactor's licence from FirstEnergy in December. The reactor has been closed since 1979, when it partially melted down during the most serious accident at a commercial nuclear plant in US history.
