What happened in Fukushima
On March 11 there was an earthquake measuring 8.9 on the Richter scale, in northwestern Japan and generated a tsunami with waves up to 10 meters high, which hit the port city of Sendai.
Of the five reactors in Fukushima three were in operation, which automatically turn off the insertion of the safety bars.
According to the security design should serve the emergency cooling system, which he had two sources of energy to pump, diesel generator and batteries.
The tsunami destroyed leaving only the diesel generator batteries to extract waste heat is about 3% of the total heat of reactor when it was working. This battery only lasts 8 hours and in this case was insufficient. As the heat was excessive in the absence of cooling, melted some pods that enclose allowing fission products release, the damage was informed by the International Atomic Energy Agency (IAEA) is shown :
