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.

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.
Normally in a nuclear power plant the heat generated by the fission process is drawn off to produce power. A nuclear meltdown occurs when the systems responsible for doing so are damaged or fail and the fissile materials (uranium, plutonium ect) used to generate energy in the plant get hot enough to melt themselves and their containers. When this happens not only is the core of the reactor damaged, making unusable until repaired, but the radioactive fissile materials could be released in to the environment.

Meltdown is a term that describes the melting of a nuclear-reactor core as a result of a nuclear accident

Nowhere as far as I can find. Perhaps you are thinking of the 1986 Chernobyl steam explosion and graphite fire. This was in the USSR and although the graphite fire melted much of the core, it was not a meltdown in the usual sense associated with nuclear reactors.

What happens to a stars nuclear energy generation change if the core decreases in temperature?
I guess everything melts at a certain speed, at about 1 mile of ice per hour. The chain reaction of nuclear particles gets out of control and carries on until the heat produced melts the metal of the place where the reaction is taking place and radiation is let out with an explosion.
