These light water reactors [2] drove electrical generators with a combined power of 4.7 GWe, making Fukushima Daiichi one of the 15 largest nuclear power stations in the world. Fukushima was the first nuclear plant to be designed, constructed, and run in conjunction with General Electric and Tokyo Electric Power Company (TEPCO). [3]
Units 1 through 4 at the plant. At the time of the earthquake, Unit 4 had been shut down for shroud replacement and refueling since 29 November 2010. [1] [2] All 548 fuel assemblies had been transferred in December 2010 from the reactor to the spent fuel pool on an upper floor of the reactor building [3] where they were held in racks containing boron to damp down any nuclear reaction.

On 24 March, electrical power (initially from temporary sources, but off-site power used from 3 April) was restored to parts of the unit which included the Main Control Room. [35] [42] The IAEA reported temperatures on 27 March at the bottom of Unit 2's Reactor Pressure Vessel (RPV) fell from 100 °C (212 °F) to 97 °C (206.6 °F). While ...
Highly radioactive water leaked from a treatment machine at the tsunami-hit Fukushima Daiichi nuclear power plant, but no one was injured and radiation monitoring shows no impact to the outside ...
[2] [3] Overall, the plant had 6 separate boiling water reactors originally designed by General Electric (GE), and maintained by the Tokyo Electric Power Company (TEPCO). In the aftermath, Unit 3 experienced hydrogen gas explosions and suffered a partial meltdown , along with the other two reactors ( 1 & 2 ) in operation at the time the tsunami ...
For the wrecked Fukushima Daiichi nuclear plant, managing the ever-growing volume of radioactive wastewater held in more than 1,000 tanks has been a safety risk and a burden since the meltdown in ...
On 28 December at a meeting in the city of Fukushima minister Goshi Hosono asked the local leaders of prefecture Fukushima for permission to build an interim storage facility somewhere in the county of Futaba near the two villages hosting the Fukushima Daiichi Nuclear Power Plant. Local residents, however, were seriously divided.
A drone almost the size of a slice of bread is Japan’s newest hope to get clearer footage of one of the reactors inside the tsunami-hit Fukushima Daiichi nuclear power plant where hundreds of ...
