Under the worst possible conditions, a meltdown can occur in a nuclear submarine. It is an event of low probability, however.
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.
No. There is no possibility whatsoever of a nuclear power plant having a nuclear explosion. It is not physically, or even theoretically, possible for the core to be brought into a super-prompt critical geometry and held there long enough to consume enough fuel to "go nuclear".
A nuclear reactor exploded in 1986 at the Chernobyl Nuclear Power Plant in Ukraine. The explosion released a large amount of radioactive material into the atmosphere, making it one of the worst nuclear disasters in history.
Chernobyl, Ukraine, 1986
Worst case scenario, if the Japan nuclear reactors have a complete meltdown, then there is a possibility that the radiation can travel in the Jet Stream to the western coast of the U.S. To protect yourself from the radiation, iodine supplements are available at your local drug store.
I think it was Chernobyl Nuclear Power Plant in 1986.Another Answer:Chernobyl was the worst. Fukushima Daiichi was second.
The Chernobyl nuclear accident.
The Chernobyl nuclear power plant exploded on April 26, 1986. It was the worst nuclear disaster in history.
Chernobyl is famous for the worst nuclear power plant accident in history.
We pretty much already had it.
The #4 reactor is the reactor at the Chernobyl Nuclear Power Plant (Pripyat, Ukraine) that exploded on April 26, 1986. It is still the worst nuclear accident to ever take place anywhere.
