Images taken by miniature drones from deep inside a badly damaged reactor at the Fukushima nuclear plant show displaced control equipment and misshapen materials but leave many questions ...
Normal radiation dose rates at the Fukushima I site as established by the stream of monitoring post readings in the 3 months preceding the accident. (03/01=1 March 2011, 1 Gray= 1 Sv for gamma radiation) [98] Radiation fluctuated widely on the site after the tsunami and often correlated to fires and explosions on site.
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 ...
TEPCO needs to find and repair the damaged parts of the reactor to recover melted nuclear fuel before TEPCO can begin the process of decommissioning the reactor. However high radiation often stops workers from entering the building. This scenario means it will take a long time to find the problems in the containment vessel. [62]
Watch a view of Japan's Fukushima nuclear power plant on Friday, 25 August, as it begins to discharge treated radioactive water into the Pacific Ocean. A massive earthquake and tsunami caused ...
The Fukushima prefectural government reported radiation dose rates at the plant reaching 1.015 m Sv/h. [59] The IAEA stated on 13 March that four workers had been injured by the explosion at the Unit 1 reactor, and that three injuries were reported in other incidents at the site. They also reported one worker was exposed to higher-than-normal ...
The prime example of a "major nuclear accident" is one in which a reactor core is damaged and significant amounts of radioactive isotopes are released, such as in the Chernobyl disaster in 1986 and Fukushima nuclear disaster in 2011.
The Fukushima workers had to be wary of radiation spiking—a sudden and unforeseen rise in radiation. [28] This threat forced the workers to evacuate for a short period of time on the morning of Tuesday 15 March 2011 when radiation detected at Fukushima rose to approximately 1000 mSv/h, [ 29 ] the highest level of radiation detected at any ...
