Okuma, Japan -- Officials at an embattled nuclear power plant in the northeast of Japan are desperately trying to cool down a nuclear reactor in the brink of a possible meltdown after a failed shutdown in the wake of Friday's devastating M8.9 earthquake. According to officials from the Tokyo Electric Power Company (Tepco), cooling systems at another reactor inside the Fukushima I Nuclear Power Plant also failed hours after an explosion at reactor no. 1 occurred, stoking fears of a meltdown. The company has clarified that the explosion was caused not by a meltdown, but by hydrogen gas which formed after workers pumped seawater in the superheated reactor to cool it down. The hydrogen gas was allowed to escape in order to relieve pressure inside the reactor causing the explosion which destroyed the reactor's concrete housing but not the reactor itself.
