Following a major earthquake, a 15-metre tsunami disabled the power supply and cooling of three Fukushima Daiichi reactors, causing a nuclear accident beginning on 11 March 2011 . All three cores largely melted in the first three days.
When was the Fukushima power plant meltdown?
The Fukushima accident was an accident in 2011 at the Fukushima Daiichi (“Number One”) nuclear power plant in Japan. It is the second worst nuclear accident in the history of nuclear power generation, behind the Chernobyl disaster.
What happened at the Fukushima nuclear power plant in 2011?
What happened at Fukushima? Systems at the nuclear plant detected the earthquake and automatically shut down the nuclear reactors . ... But soon after a wave over 14 metres (46ft) high hit Fukushima. The water overwhelmed the defensive sea wall, flooding the plant and knocking out the emergency generators.
Did reactor 2 explode in Fukushima?
Explosion. An explosion was heard after 06:14 JST on 15 March in Unit 2, possibly damaging the pressure-suppression system, which is at the bottom part of the containment vessel.
When did the Fukushima Daiichi nuclear disaster end?
The Fukushima Daiichi nuclear disaster occurred after a 9.0 magnitude Tōhoku earthquake and subsequent tsunami on 11 March 2011 .
Is Fukushima worse than Chernobyl?
Chernobyl is widely acknowledged to be the worst nuclear accident in history, but a few scientists have argued that the accident at Fukushima was even more destructive. Both events were far worse than the partial meltdown of a nuclear reactor at Three Mile Island near Harrisburg, Pennsylvania.
How many of the Fukushima 50 have died?
More than 22,000 people died or are presumed to have died in the disaster, which also destroyed tens of thousands of buildings, and catalyzed a triple nuclear meltdown, three hydrogen explosions and the release of radioactive contamination at the Fukushima No.

What is the most radioactive place on earth?
1 Fukushima, Japan Is The Most Radioactive Place On Earth
Fukushima is the most radioactive place on Earth. A tsunami led to reactors melting at the Fukushima nuclear power plant.
Is Fukushima in Tohoku?
The Tōhoku region (東北地方, Tōhoku-chihō), Northeast region, or Northeast Japan (東北日本, Tōhoku-nihon) consists of the northeastern portion of Honshu, the largest island of Japan. This traditional region consists of six prefectures (ken): Akita, Aomori, Fukushima, Iwate, Miyagi, and Yamagata.
How many Fukushima reactors exploded?
Following a major earthquake, a 15-metre tsunami disabled the power supply and cooling of three Fukushima Daiichi reactors, causing a nuclear accident beginning on 11 March 2011. All three cores largely melted in the first three days.
How long will Fukushima be uninhabitable?
A large area around the Fukushima nuclear power plant will be uninhabitable for at least 100 years .
How long did it take for the tsunami to hit Fukushima?
— March 11, 2011: A magnitude 9.0 earthquake strikes off the coast at 2:46 p.m., triggering a towering tsunami that reaches land within half an hour . The tsunami smashes into the Fukushima Daiichi nuclear plant, destroying its power and cooling systems and triggering meltdowns at three reactors.
Which reactor exploded first in Fukushima?
Hydrogen explosions
As workers struggled to supply power to the reactors’ coolant systems and restore power to their control rooms, three hydrogen-air chemical explosions occurred, the first in Unit 1 on 12 March, and the last in Unit 4, on 15 March.
How is Fukushima being cleaned up?
In 2022, workers will test a remotely operated mechanical arm to retrieve small amounts of fuel debris believed to be at the bottom of the Unit 2 reactor. The other major challenge is disposing of water that gets contaminated as it circulates through the reactors to remove residual heat from the fuel debris.
