The earthquake which was caused by 5 to 8 meters upthrust on 180-km wide seabed at 60 km offshore from the east coast of Tohoku resulted in a major tsunami. The earthquake took place on March 11, 2:46 P.M and initial estimates indicated that the major tsunami would have taken 10 to 30 minutes to reach the affected areas first.
The Fukushima I and Fukushima II were automatically shut down following the earthquake. Cooling is necessary to remove decay heat after a reactor has been shut down, and to sustain spent fuel pools. The backup aplomb process is powered by emergency diesel generators at the plants. After Japan is rocked by the 8.9 earthquake, the tsunami waves approaches Fukushima Dai-ichi thermonuclear plant. Inside are 3 reactors. Diesel generators are pumping water around the reactors to cool the fuel rods. But these generators must stay dry. The plants are impede by seawalls that are eighteen feet high.
But the seawalls prove no avail against the fourty-five foot wave. Swamped by the waves, the diesel generators are destroyed. in that respect is something very important that has to happen after an automatic culmination to immediately cool down the reactor. Now there is lone(prenominal) one back-up cooling system left, the battery operated pumps, but they just have an eight hour charge and time is tally out. Fukushima Dai-ichi nuclear plant is gradually leading to a nuclear meltdown. At
It was just an ordinary Friday afternoon. At 2:46 P.M. local time, Japan was struck with an 8.9 earthquake off the northeastern coast of the island. The quake struck right off of Honshu, which is...If you urgency to get a full essay, order it on our website: Orderessay
