Chernobyl
Chernobyl, Ukraine, in 1986
One of the four reactors at Chernobyl
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).
The meltdown probably occurs due to loss of power, so the question does not make sense
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 Obninsk Nuclear Power Plant, which was the first nuclear power plant to generate electricity for a power grid in the world, did not experience a meltdown. It operated safely from its commissioning in 1954 until its closure in 2002. While there were some operational challenges and incidents during its lifetime, none resulted in a catastrophic failure or meltdown.
The largest nuclear plant meltdown happened at the Chernobyl Nuclear Power Plant in Ukraine on April 26, 1986. The explosion and subsequent fire released large amounts of radioactive material into the atmosphere, resulting in one of the worst nuclear disasters in history.

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.
Nuclear power accidents are a disaster. The 1986 nuclear accident at the Chernobyl Nuclear Power Plant in Ukraine was a catastrophic accident.
