A nuclear meltdown is an informal term for a severe nuclear reactor accident that results in core damage from overheating. A core melt accident occurs when the heat generated by a nuclear reactor exceeds the heat removed by the cooling systems. A meltdown is considered a serious event because of the potential, however remote, of radioactive material being released into the environment.
The worst nuclear disastors in history were the Three Mile Island and Chernobyl.
How do these disasters compare to whats happening in Japan right now?
