It’s been 12 years since the catastrophe at Fukushima Daiichi, and decommissioning the site continues to be a major headache.
Japan's Nuclear and Industrial Safety Agency gives new estimates of the times at which the reactor pressure vessels were damaged and possibly dropped fuel into the containment vessels: 5 hours after the initial earthquake for reactor 1 (20:00 March 11); 80 hours for reactor 2 (22:50 March 14); and 79 hours for reactor 3 (22:10 March 14).

Tepco-workers were able to enter the building of reactor 2 a month later where they installed and replaced a provisional gauge for measuring the water level inside the reactor. The results were disappointing, as 2 days later Tepco reported that it was still not possible to obtain accurate data on the water level and pressure from Unit 2.
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.

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 ...
Nitrogen injections were later repeated on the other units at Fukushima. [82] As the inside of the reactor building is now lethal to humans, a remote control robot was used to enter the building on 17 April and performed a series of inspections that lasted almost 2 weeks. [74]
One of the most notable meme NFTs is "Disaster Girl," which sold for a staggering $500,000. This image of a young girl smirking in front of a burning house became iconic online.
The Fukushima disaster cleanup is an ongoing attempt to limit radioactive contamination from the three nuclear reactors involved in the Fukushima Daiichi nuclear disaster that followed the earthquake and tsunami on 11 March 2011. The affected reactors were adjacent to one another and accident management was made much more difficult because of ...
