I found this article on Japan. And so the overheating came to be because of power failure.
If the reactor’s fuel rods aren’t cooled, the reaction can burn out of control. That’s what happened at the two Japanese plants after the quake and tsunami caused a power failure and the cooling systems malfunctioned. This overheating could cause radiation to escape and sicken many people.
