At the Fukushima nuclear power plant, the gigantic wave surged over defences and flooded the reactors, sparking a major disaster. Authorities set up an exclusion zone which grew larger and larger as radiation leaked from the plant, forcing more than 150,000 people to evacuate from the area.10-Mar-2021
What happened at Fukushima Daiichi and why it is significant?
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 did the Fukushima disaster affect the world?
More than one million buildings were damaged, and more than four million people lost their electricity supply. Many industrial facilities were affected, resulting in significant damage and irreversible environmental impacts.
Why did Fukushima explode?
The hydrogen explosion in reactor 4 was caused by hydrogen coming out from the spent fuel pool. In that pool, there were (and are) used nuclear fuel rods that released and still release decay heat. As the water level dropped, the used fuel rods were exposed to the air and hydrogen was formed.
What did we learn from Fukushima?
The overarching lesson learned from the Fukushima Daiichi accident is that nuclear plant licensees and their regulators must actively seek out and act on new information about hazards that have the potential to affect the safety of nuclear plants.
Why was Chernobyl worse than Fukushima?
Chernobyl had a higher death toll than Fukushima The toxic fumes not only contaminated the local vegetation and water supply near Pripyat (a Ukrainian city that was once part of the Soviet Union) but also poisoned nearby residents, some of whom went on to develop cancer.
Is Fukushima still leaking radiation 2021?
The radiation levels offshore of Fukushima have dropped in the years since, but some of the reactors there are still leaking. And over the last decade, TEPCO has continued to cool the fuel cores with water, which is contaminated by the process.
How much damage did Fukushima cause?
The earthquake and tsunami damaged or destroyed more than one million buildings leading to a total of 470,000 people needing evacuation.
What is the most radioactive place on earth?
2 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. Even though it's been nine years, it doesn't mean the disaster is behind us.
Where did the Fukushima Daiichi accident occur?
Fukushima accident, also called Fukushima nuclear accident or Fukushima Daiichi nuclear accident, accident in 2011 at the Fukushima Daiichi (“Number One”) plant in northern Japan, the second worst nuclear accident in the history of nuclear power generation.
