There have been other meltdowns, notably in Soviet submarines and the icebreaker Lenin. It is thought that there may have been others that are either unreported or unconfirmed. Also, there are other ways nuclear material can be spread into the environment, such as happened at the Kyshtym disaster, in the Soviet Union in 1957, when an explosion released 70 to 80 tonnes of nuclear waste into the environment, or the Goiânia accident, in Brazil in 1987, when something less than a tenth of a liter of radioactive cesium was improperly distributed, killing several people and contaminating hundreds more.

Where and when did the nuclear meltdown at three mile island happen?
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.
When fuel rods in the reactor core of a nuclear power plant melt due to exposure to too much heat it is known as what?
nuclear meltdown .-. '
How do you stop or slow the nuclear reaction in a nuclear power plant?
Once a meltdown occurs at a nuclear power plant, there is no way to stop or slow the reaction. However, Nuclear power plants are the most technologically advanced power plants in the history of man-kind. The meltdowns themselves are incredibly rare, but if they do occur the immediate areas are instantly alerted and evacuated. The contamination of the surrounding area is typically not very quick to begin with, as the walls of structures of Nuclear Power Plants are very thick and designed to withstand nearly anything thrown at them. Of anything that could happen, a meltdown at your area Nuclear Power Plant should be at the very bottom on your list of concerns.
How does a meltdown occur?
When fuel rods in a nuclear power plant generate too much heat, they start to melt.
What is effect if nuclear reactor fail?
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.
What nuclear power plant had a meltdown in Ukraine?
Chernobyl

What was the most severe nuclear power plant meltdown?
Chernobyl, Ukraine, in 1986
Why don't they disassemble the Fukushima nuclear plant?
because its having a meltdown at the moment
How do you power a meltdown nuclear power plant?
The meltdown probably occurs due to loss of power, so the question does not make sense
What nuclear power plant had a meltdown in Ukraine in 1986?
One of the four reactors at Chernobyl
What is the danger of a nuclear plant meltdown?
The danger in a nuclear plant meltdown is that failure of the containment system may follow the meltdown, and this will allow highly radioactive material out into the environment. Let loose, this material can injure or kill exposed individuals, and it can render large areas of land uninhabitable for long periods of time.
Where did the worst Nuclear plant meltdown take place?
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).
What happend in chernobyl?
there was a meltdown at a nuclear plant that caused irrevoable damage and nuclear posioning for generations to come. It is still considered dangerous to go there.
