The Three Mile Island accident was a nuclear meltdown which occurred at the Three Mile Island power plant in Dauphin County, Pennsylvania, United States on March 28, 1979.
A nuclear meltdown is an informal term for a severe nuclear reactor accident that results in core damage from overheating. A meltdown occurs when the heat generated by a nuclear reactor exceeds the heat removed by the cooling systems to the point which at least one nuclear fuel plate exceeds its melting point.
This sounds like a nuclear core meltdown, reactor meltdown, or just a meltdown.

Under the worst possible conditions, a meltdown can occur in a nuclear submarine. It is an event of low probability, however.
