Three nuclear power plant reactors in Japan are reaching critical conditions. If these three nuclear reactors can not be cooled down, they risk a meltdown and major catastrophy for Japan and the world. A partial meltdown was likely under way at a second nuclear reactor, a top Japanese official said Sunday, as authorities frantically tried to prevent a similar threat from nearby unit following a catastrophic earthquake and tsunami. Some 170000 people have been ordered to evacuate the area covering a radius of 12 miles (20 kilometers) around the plant in Fukushima near Iwaki. A meltdown refers to a very serious collapse of a power plant's systems and its ability to manage temperatures. A complete meltdown would release uranium and dangerous byproducts into the environment that can pose serious health risks. Japan dealt with the nuclear threat as it struggled to determine the scope of the twin disasters Friday, when an 8.9-magnitude earthquake, the most powerful in its recorded history, was followed by a tsunami that ravaged its northeastern coast with breathtaking speed and power. The quake and tsunami damaged three reactors at the Fukushima Dai-ichi nuclear plant, which lost their cooling functions necessary to keep the fuel rods functioning properly.
