Short answer: 2
More details: There have only been two full meltdowns, both in Ukraine (Prypait and Chernobyl). These were due to inadequate safety systems, as the USSR didn't exactly care about the safety of it's citizens. There have, however, been many partial meltdowns. These are usually due to one of the following:
• Simultaneous human and machine error (neither the machines nor the technicians noticed a problem).
• Massive human error (Human error so bad, the machines were incapacitated and couldn't detect the human error.
When adequate safety systems are in place (as they are in every operational power plant today as required by both the UN and the EU), on the off chance that something goes wrong, it can be fixed hours before anybody is exposed to radioactive material. Nuclear power is the safest non-renewable method of power production, and safer than every renewable method except for solar. It is also extremely cost effective, costing less in maintenance and fuel than coal, oil, gas, hydro, wind, tidal, and solar, and the same price as geothermal (but quicker and on a larger scale).

How many reactors in Chernobyl melted down?
One reactor at the Chernobyl nuclear power plant melted down in the 1986 disaster.
Are there nuclear power plants in Nebraska?
There are no licenced nuclear power plants in Utah. There is one research reactor at the University of Utah. Such a reactor is not licenced the way commercial reactors are, in part because they are supposedly incapable of melting down. They are used for a variety of purposes, including making radionuclides used in medicine.
Can you shut down a nuclear power plant?
Yes, nuclear power plant can be shut down.
How do nuclear cooling towers work to regulate the temperature of nuclear power plants?
Nuclear cooling towers work by releasing excess heat from the nuclear power plant into the atmosphere. Water is used to cool down the hot water from the reactor, which then evaporates and releases heat through the tower. This process helps regulate the temperature of the nuclear power plant and prevent overheating.
Why nuclear power plant is dangerous?
A nuclear power plant is no more dangerous than a fossil power plant. In fact, taking into account the global picture, it is less dangerous, from an economic, and an ecological standpoint. This may seem counter-intuitive, but the fact is that radiation hazard is mitigated by the dilution effects of the atmosphere and oceans and, looking at the big picture, nuclear power plants are safer than fossil power plants, hands down.

How can there be a nuclear disaster in Japan?
The tsunami wiped out almost all of Japan knocking down many buildings such as skyscrapers and nuclear power plants that were operating in Japan. The tsunami destroyed the nuclear power plants and radiation leaked out which caused a raging panic among the people of Japan.
Can you shut down a nuclear power plant?
Yes, nuclear power plant can be shut down.
How did the power plants on the map increase the danger of damage and risk to human life after the March 2011 earthquake?
They melted down and leaked radiation into the ground and the air.
What state is the safest distance from all US nuclear plants in the event of a nuclear melt down?
You would have to be atleast 30 miles away from an individual nuclear power plant to get away from the deadly amounts of radiation.

What continent has the worlds worst nuclear disaster?
Asia, specifically the Chernobyl Disaster in the former Soviet Union (Russia), in which a nuclear power plant went critical and melted down, rendering the city uninhabitable and causing radioactive clouds to travel globally.
Nuclear power plants in Ohio?
There were three of them, but one has been permanently shut down. (See link below)
Is nuclear power plants are bad for earth?
Not normally. If they melt down, they can cause extreme damage. But generally it is a source of good, clean energy.
