A partial meltdown is a term for a type of severe nuclear reactor accident. In this situation, the cooling and safety systems of a reactor have failed to the point where the core overheats severely. In this instance, the nuclear fuel, which is welded inside tubes or plates, becomes so hot that it melts its way through the metal (called cladding) encasing it. This contaminates the whole reactor with highly radioactive material. A partial meltdown is generally contaned within the reactor vessel or the containment structure. But the reactor and associated cooling systems will end up highly contaminated with radioactive materials and be unusable.
A meltdown at a nuclear power plant occurs when the reactor core overheats to the point where the fuel rods melt, releasing radiation into the environment. This can lead to a loss of containment and the potential for widespread contamination. Emergency measures, such as cooling the reactor and preventing the release of radioactive materials, are taken to mitigate the impact of a meltdown.
There is no such thing as a blast radius of a meltdown, provided it is contained in the reactor pressure vessel. If the vessel bursts, then it's another matter, but it is most likely to crack and relieve pressure that way, so very unlikely to produce a blast.
A meltdown is when the uranium or plutonium fuel burns through the zirconium oxide outer layer of the fuel rod and melts down into a pool of molten radioactive material in the bottom of the reactor chamber until it burns through the reactor vessel and the ground until it hits the water table when it explodes in a cloud of radioactive material into the atmosphere and scatters all around the world.
Fukushima Daiichi had a partial meltdown in consequence to the tsunami of March 2011 in Japan.
During the Chernobyl nuclear power plant meltdown, temperatures reached up to 4000 degrees Celsius in the reactor core due to the uncontrolled nuclear chain reaction.
The Fukushima Nuclear Power plant is a Japanese nuclear power plant in which the reactor meltdown occurred after the tsunami and earthquake in 2011. It is a site of paramount historical global significance to the nuclear energy and safety sector.
The first controlled nuclear reaction took place in 1942 at the University of Chicago. The first nuclear meltdown occurred at the Chernobyl Nuclear Power Plant in 1986, which is 44 years later.
When fuel rods in a nuclear power plant's reactor core melt due to exposure to excessive heat, it is known as a meltdown. This can lead to the release of radioactive materials into the environment and poses serious safety risks.
The nuclear meltdown at Three Mile Island occurred in Middletown, Pennsylvania, United States on March 28, 1979. It was the most serious accident in the history of the American commercial nuclear power generating industry.
Chernobyl
The meltdown probably occurs due to loss of power, so the question does not make sense
Chernobyl, Ukraine, in 1986
One of the four reactors at Chernobyl
chernobl power plant meltdown
Chernoybl Nuclear Power Plant Meltdown Except that happened on April 26, 1986.
The worst nuclear accident occurred on 26 April 1986 at the Chernobyl Nuclear Power Plant in the Ukraine (under the management of authorities in Moscow).
When fuel rods in a nuclear power plant's reactor core melt due to exposure to excessive heat, it is known as a meltdown. This can lead to the release of radioactive materials into the environment and poses serious safety risks.
A meltdown occurs in a nuclear reactor when the core overheats and the fuel rods are damaged, releasing radioactive material. This can happen due to a loss of coolant, causing the fuel rods to become exposed and overheat. If not controlled, this can lead to a breach of the reactor containment and a release of radiation into the environment.

It didn't explode. Three Mile Island's Nuclear Power Plant in Pennsylvania experienced an almost complete meltdown.
Umm... I think it was the Three Mile Island accident
