[35] [38] As of 21 October 2011, the largest study on Fukushima fallout concludes that Fukushima was "the largest radioactive noble gas release in history not related to nuclear bomb testing. The release is a factor of 2.5 higher than the Chernobyl 133 Xe source term", although the "Xenon-133 [main noble gas] does not pose serious health risks ...
Globally, there have been at least 99 (civilian and military) recorded nuclear power plant accidents from 1952 to 2009 (defined as incidents that either resulted in the loss of human life or more than US$50,000 of property damage, the amount the US federal government uses to define nuclear energy accidents that must be reported), totaling US$20.5 billion in property damages.
A cover was constructed around the damage reactor of the Chernobyl nuclear plant. This helps in the remediation of radioactive material leaking from the site of the accident, but does little to protect the local area from radioactive isotopes that were dispersed in its soils and waterways more than 30 years ago.
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 ...
The Fukushima disaster in 2011 set off a wave of anti-nuclear sentiment globally, in the immediate aftermath. Critics pointed to the events as a wake up call that highlighted the inherent risks ...
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 ...
For the wrecked Fukushima Daiichi nuclear plant, managing the ever-growing volume of radioactive wastewater held in more than 1,000 tanks has been a safety risk and a burden since the meltdown in ...
