How long is Fukushima uninhabitable?
100 years
A large area around the Fukushima nuclear power plant will be uninhabitable for at least 100 years.
How many people are still displaced from Fukushima?
Some 40,000 people are still displaced by the disaster, unable to return home to areas near the wrecked plant that are still off-limits due to radioactive contamination. The government has spent about $300 billion to rebuild the region, but safely decommissioning the plant will take decades and billions of dollars.
How many Fukushima reactors melted down in March 2011?
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.
Is Fukushima core still hot?
It has now fallen to around 90 °C, and temperatures in Units 2 and 3 are also hovering around 100 °C. The cooling water injected into the reactor cores is being heated to boiling point, so workers must continually replenish it.
What was bigger Chernobyl or Fukushima?
A 2013 study from Colorado State University found that Fukushima released about 520 petabecquerels of radioactive material compared with the 5,300 petabecquerels released by Chernobyl. While Chernobyl’s radiation spread throughout Europe, much of Fukushima’s radiation was released into the Pacific Ocean.
What happened to the spent fuel rods at Fukushima?
In November 2013, operators at the Fukushima plant started removing some 1,500 spent fuel rods from damaged reactor No. 4, which was not operational and was being used as temporary storage at the time of the accident.
How are spent fuel rods removed from nuclear power plants?
The spent fuel rods will be removed from the damaged reactor building in a four-step process. Using a remotely operated machine, workers at the plant will transfer the fuel assemblies one by one from the pool into an underwater transport container. The container will be sealed, cleaned, then loaded via crane onto a truck.
What happened at Fukushima Daiichi?
Eight years after a 9.0 magnitude earthquake triggered Japan’s worst ever nuclear disaster, work has begun to remove spent fuel rods from a reactor that went into meltdown at Fukushima Daiichi nuclear power station.
How long does it take to clean up a nuclear reactor?
Remotely controlled equipment is lifting fuel rods from a storage pool near reactor number three. The delicate work at the contaminated site is expected to take two years. The next phase of the huge clean-up at reactor three will be to remove molten nuclear fuel that remains deep inside.
