The fire lasted for days to weeks, and there is controversy over whether it was the fuel burning, nuclear decay heating or whether the graphite moderator that made up most of the core was involved. See Chernobyl Disaster , Note 1, for more discussion.
[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 ...
In 2011, an earthquake and tsunami caused a loss of electric power at the Fukushima Daiichi nuclear power plant in Japan (via severing the connection to the external grid and destroying the backup diesel generators). The decay heat could not be removed, and the reactor cores of units 1, 2 and 3 overheated, the nuclear fuel melted, and the ...
Europe's largest nuclear power plant was hit by Russian shelling early Friday, sparking a fire and raising fears of a disaster that could affect all of central Europe for decades, like the 1986 ...
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 ...
Japan is poised to amp up its use of nuclear power to meet national energy needs after a 13-year pause in the wake of the 2011 Fukushima disaster, according to a new strategy document released on ...
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.
At a small section of the Fukushima Daiichi nuclear plant’s central control room, the treated water transfer switch is on. A graph on a computer monitor nearby shows a steady decrease of water ...
