There was a reactor core meltdown. Pilots flying above it couldn't get near it without absorbing horrible radiation.

What city is like the city of Chernobyl today?

Chernobyl was the only large-scale abandonment of a city due to a nuclear disaster in history. By comparison, Nagasaki or Hiroshima could be used, as they were the sites of atomic bombings during WW2, but the people returned after the blast, regardless of the radiation. Unlike the latter examples, Chernobyl remained completely uninhabited after the 1986 nuclear meltdown at a power plant a few miles from the city. The population of Chernobyl was bordering on 10,000 people before the explosion, and the 2010 population census revealed that only about 500 people remained there after the meltdown.


In what ways did the incident at Three Mile Island differ from that at Chernobyl?

The Three Mile Island incident in 1979 was a partial meltdown resulting from equipment malfunctions and operator errors, with no immediate fatalities and limited off-site impact. In contrast, the Chernobyl disaster in 1986 was a full-scale meltdown caused by a flawed reactor design and operator errors, resulting in immediate deaths, widespread radioactive contamination, and long-term health and environmental consequences.


What does chernobyl and 3 mile islands have in common?

Both Chernobyl and Three Mile Island are well-known nuclear disasters that caused widespread environmental and health impacts. Both incidents resulted in the release of radioactive materials into the environment and raised concerns about nuclear safety and regulation. Additionally, they both led to significant changes in the nuclear industry and a reassessment of nuclear power plants' safety measures.


What were important political events in the 70's?

The attempted assisnation of president Ronald Regan, that happened in the early 80's. Robert Kennedy while running for president was shot in the 70's. Chernobyl (in Russia) biggest nuclear disaster, happened in the 80's. Berlin Wall (in Germany) came down, I think in 1989. I know there was some kind of gas shortage in the late 70's that was a big deal. Iran - Iraq war in late 70's, we were involved in something with some hostages.


How are the meltdowns at Chernobyl and Three Mile Island similar and how are they different?

In brief, both accidents involve gross failure of a nuclear reactor. The two reactors are of different types, so there are some things that are unique to each plant. Both had the reactor cores damaged catastrophically. And in both cases, radiation was released ourside fuel element cladding and outside containment barriers. What is different is that in the Chernobyl disaster, the atomic pile caught fire. I was built using graphite blocks for moderators. At Three Mile Island (TMI), there was no fire. The radiation released at TMI was some nasty stuff including fission fragments from failed fuel element cladding, but it was released in limited quantities. TMI was an accident. In Russia, things were different. It was a disaster. At Chernobyl, as the core burned, massive clouds of highly radioactive fission byproducts (from the failed fuel elements) were caught up in the fire column and swept aloft with the smoke and heat. This caused the surrounding area to have to be evacuated and some of it was actually abandoned. The small city of Pripyat became a ghost town. This newly constructed community of about 50,000 or so was abandoned. People just walked away. They literally left everything behind and departed with just the clothes on their backs. There were a number of fatalities at Chernobyl, and none at TMI. Some reactor workers and a number of emergency personnel responding to the fire died of radiation sickness. And a number of civilians lost their lives within a few weeks of the accident. One account logged by a helicopter pilot (several choppers dumped water on the fire from aloft) said that in the night, the column of smoke and debris from the fire glowed in the darkness due to the radioactivity. Helicopter pilots were among those who died as a result of their heroic efforts to douse the flames. Links are provided to relevant Wikipedia articles.
