What nuclear reactor went off in Japan?

Fukushima Daiichi reactors
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 much radiation did Fukushima release?

In 2014 Fukushima University’s Institute of Environmental Radioactivity said that the total amount of Cs-137 released was 20.5 PBq, 17 PBq to the air, and of the total, 12 to 15 PBq ended up in the Pacific Ocean. The 17 PBq to air, coupled with the I-131, would give 810 PBq (I-131 eq).

What happened to the nuclear plant in Japan?

Japan earthquake: Explosion at Fukushima nuclear plant. Read more about sharing. A powerful explosion has hit a nuclear power station in north-eastern Japan which was badly damaged in Friday’s devastating earthquake and tsunami. A building housing a reactor was destroyed, but authorities said the reactor itself was intact.

What happened to the Fukushima Daiichi reactors?

In July 2019 Tepco announced its decision to decommission the four reactors. Japan’s Nuclear & Industrial Safety Agency originally declared the Fukushima Daiichi 1-3 accident as level 5 on the International Nuclear Events Scale (INES) – an accident with wider consequences, the same level as Three Mile Island in 1979.

What happened to the Chernobyl nuclear reactor?

The resultant loss of reactor core cooling led to three nuclear meltdowns, three hydrogen explosions, and the release of radioactive contamination in Units 1, 2 and 3 between 12 and 15 March.

What kind of radiation was released from Fukushima?

(See also background on Fukushima Fuel Ponds and Decommissioning section below.) Regarding releases to air and also water leakage from Fukushima Daiichi, the main radionuclide from among the many kinds of fission products in the fuel was volatile iodine-131, which has a half-life of 8 days.
