The Fukushima nuclear accident was a major nuclear accident at the Fukushima Daiichi Nuclear Power Plant in Ōkuma, Fukushima, Japan, which began on 11 March 2011. The proximate cause of the accident was the 2011 Tōhoku earthquake and tsunami , which resulted in electrical grid failure and damaged nearly all of the power plant's backup energy ...
The total amount of radioactive material still stored at Fukushima is about 8 times that stored at Chernobyl, and leakage at Fukushima continues. After cooling efforts at spent-fuel pool 4 were halted, due to an erroneous warning about the pool filling up, [ 176 ] the temperature of the pool rises to 90 °C and the dose rate 6 meters above the ...
As of August 2011, the crippled Fukushima nuclear plant is still leaking low levels of radioactive material and areas surrounding it could remain uninhabitable for decades due to high radiation. It could take "more than 20 years before residents could safely return to areas with current radiation readings of 200 millisieverts per year, and a ...
Japan on Monday marked 13 years since a massive earthquake and tsunami hit the country’s northern coasts. Nearly 20,000 people died, whole towns were wiped out and the Fukushima Daiichi nuclear ...
About 20,000 of more than 160,000 evacuated residents across Fukushima still haven't returned home. Decontamination work before the Tokyo Olympics meant to showcase Fukushima’s recovery led to the elimination of some no-go zones, but they remain in seven of 12 towns that had been fully or partially off-limits.
Japan marked the 13th anniversary of the massive earthquake and tsunami that triggered a nuclear meltdown and left large parts of Fukushima prefecture uninhabitable on Monday with a minute of ...
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 ...
In less than 16 hours, the reactor core melted [42] and dropped to the bottom of the pressure vessel, burning a hole through the vessel. By that time, water was pumped into the reactor in an effort to prevent the worst-case scenario – overheating fuel melting its way through the containment and discharging large amounts of radionuclides in ...
