About 140,000 people evacuated the area. 663,500 people remained. There was a great deal of confusion in out and out incompetence over whether an evacuation should occur. It wasn't until late into the event, that the voluntary evacuation announcement was issued.
No one. There was even a class lawsuit in which a court found a "paucity" of evidence suggesting there was any physical harm suffered by anyone.
Scientific follow-up studies showed that no member of the public was injured by the accident except for stresses caused by emotion-charged news coverage.

You are probably thinking of the Three Mile Island plant reactor melt down in 1979
Three mile Island near Harrisburg,PA March 28, 1979
I think it is just the name of the river island where the plant is located, and was called that long before nuclear power was developed, but who named it I don't know, you would have to ask the local history group if there is one.
Just to let you know there WAS a meltdown of the reactor core, caused by incompetent operators removing cooling water then they should have been adding more! But the material from the meltdown was fully contained in the core as designed. The worst concern was the possibility of a hydrogen gas explosion (as happened in Fukushima Japan) breaching the containment building, but this was prevented.The term "complete meltdown" used above has no meaning in nuclear engineering, a meltdown is any amount of core melting. One concern with meltdowns is that there may be loss of control and a resulting increase of reactivity, but there can just as easily be a decrease of reactivity and an automatic shutdown depending on the reactor design.
There were many important events in 1979. The USSR invaded Afghanistan, there was a reactor fire on Three Mile Island in Pennsylvania, and the Sahara Desert experienced snow for 30 minutes.

The Three Mile Island accident in 1979
Three mile island was the site of the worst nuclear 'accident' in america's history. The reactor went into meltdown - releasing radioactive material into the atmosphere.
Three Mile Island The accident at the Three Mile Island Unit 2 (TMI-2) nuclear power plant near Middletown, Pennsylvania occurred on March 28, 1979.
