Japan faces a nuclear crisis after the massive earthquake

The magnitude-8.9 earthquake and tsunami in Japan Friday initiated a serious nuclear power plant leakage and explosion.
In the massive earthquake, the cooling system of the Fukushima Dai-ichi plant was damaged and the government had to evacuate more than 45,000 residents within a 10-kilometre radius, the Asian Age reported.
The Asian Age reported that if the cooling system could not cool the fuel rods, it would become exposed and release radioactivity and finally it would be leading to a meltdown.
The official then decided to vent radioactive steam from a severely overheated reactor vessel but it caused a hydrogen explosion finally, the Star Tribune reported.
The Japanese broadcaster had quoted Tokyo University professor Naoto Sekimura said that there was a portion of the fuel may have melted but the reactor had already been stopped and is being cooled, the Asian Age reported.
However, if the temperature inside the Fukushima reactor vessel continued to rise, the potential risk still exists. The Star Tribune reported that some experts, who were interviewed by The Associated Press, saying any melted fuel would create the uranium and dangerous byproducts. Since the melted fuel will corrode the bottom of the reactor vessel and the floor of the already-damaged containment building, those byproducts then would start discharging into the environment.
According to the Star Tribune, another expert also said that the result of meltdown is the neighboring land would be unavailable for a period of time and a lot of first responders would die.
