At Shika Nuclear Power Plant, an explosion occurred near the power transformer of the No. 2 reactor, while the transformer at the No. 1 reactor was rendered inoperable due to an oil spill. [ 113 ] [ 215 ] The site's 4 m (13 ft) high seawall was found to have tilted by around several centimeters following the earthquake. [ 216 ]
On 21 September 2011, Masanori Naitoh, director in charge of nuclear safety analysis at the Institute of Applied Energy, an expert commenting on the plan to contain the crisis at the Fukushima Daiichi nuclear plant, mentioned that the interior temperatures of the damaged reactors had to be checked to confirm cold-shutdown.
An attempt to use an extendable robot to remove a fragment of melted fuel from a wrecked reactor at Japan’s tsunami-hit Fukushima Daiichi nuclear power plant was suspended Thursday due to a ...
However, the tsunami following the earthquake quickly flooded the low-lying rooms in which the emergency generators were housed. The flooded generators failed, cutting power to the critical pumps that must continuously circulate coolant water through a nuclear reactor for several days in order to keep it from melting down after being shut down.
