Comment related to nuclear plant by Tohoku Great Kanto Earthquake

The building of Fukushima Daichi Nuclear Power Station did not collapse though it encountered "Earthquake outside assumption" in which the specialist of the earthquake commented. Tsunami reached up to the fifth floor of a ferroconcrete building, and "Tsunami outside assumption" washed everything away. But the reactor building was healthy. The control system of the nuclear plant operated normally for the earthquake. And, the nuclear reactor stopped urgently and the dynamo worked by the steam boiled in the nuclear reactor also stopped safely. The cooling system had operated for several hours at least by the battery, though it became impossible to supply the power to control system of the nuclear plant from the outside and the diesel generator as the emergency electrical source, because its fuel tank was washed away.
Though it was on the way where the situation changed, we would like to pay our respects to the engineers who were able to hold back the accident at least. They exercise their imagination for the suppositive situation well. Whosoever could make an egg stand uprigh before Clumbus does! We admired that it is the one that can be prepared well when there is no model.
