In 2013, in response to the Fukushima Daiichi nuclear disaster, the Nuclear Regulatory Commission ordered Duane Arnold "to install a reliable hardened venting capability for pre-core damage and under severe accident conditions, including those involving a breach of the reactor vessel by molten core debris" due to the similarity in reactor design.
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 Fukushima Daiichi Nuclear Power Plant (福島第一原子力発電所, Fukushima Daiichi Genshiryoku Hatsudensho, Fukushima number 1 nuclear power plant) is a disabled nuclear power plant located on a 350-hectare (860-acre) site [1] in the towns of Ōkuma and Futaba in Fukushima Prefecture, Japan.
Treated but still slightly radioactive wastewater from the wrecked Fukushima Daiichi nuclear power plant is being released into the Pacific Ocean in a process that began Thursday — more than 12 ...
Due to international reactions to the Fukushima Daiichi nuclear disaster, concerns have continued over the ongoing operations of Diablo Canyon which, like the reactors at Fukushima, is in an area prone to earthquakes and tsunami. The elevation of the Fukushima site is approximately 20 feet (6.1 m) above sea level, while Diablo Canyon sits on a ...
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 ...
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 ...
A wall of water over 15 meters (50 feet) tall slammed into the coastal Fukushima Daiichi nuclear power plant, destroying its power supply and cooling systems, triggering meltdowns in three of its ...
