Fission products and unused fuel were lofted by the smoke of the burning graphite moderator. This fell back down as fallout (not much different from fission bomb fallout, although no nuclear explosion was involved).
Subject of an imaginative film in 1979, not a real fault
A meltdown can occur in a nuclear reactor when there is too much current flow, causing the fuel rods to overheat. This can lead to a loss of control over the nuclear reaction and the release of radioactive material.
In most reactors in the world, water is used to absorb heat released from the reactor.
An artificial nuclear reactor is a nuclear reactor that is created by man to utilize a nuclear reaction for energy, as opposed to natural nuclear reactors.
This is used in the nuclear reactor that is known as Boiling Water Reactor (BWR) in which heat produced by the nuclear fission in the nuclear fuel allows the light water reactor coolant to boil. Then, the nuclear reactor moisture separator is used to increase the dryness of the produced steam before it goes to the reactor steam turbines.
a nuclear reactor had a nuclear meltdown
This sounds like a nuclear core meltdown, reactor meltdown, or just a meltdown.
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.
The dangerous condition that can occur in a nuclear reactor and due to overheating is a nuclear meltdown.
A meltdown occurs when a severe failure of a nuclear power plant system prevents proper cooling of the reactor core, to the extent that the nuclear fuel assemblies overheat and melt. A meltdown is considered very serious because of the potential that radioactive materials could be released into the environment. A core meltdown will also render the reactor unstable until it is repaired. The scrapping and disposal of the reactor core will incur substantial costs for the operator.
Meltdown
A nuclear meltdown will be in process releasing radioactive material
It can happen if the reactor fuel rods overheat, and that can happen if they are not adequately cooled after the reactor is shutdown
