The Kashiwazaki-Kariwa Nuclear Power Plant, in Niigata Prefecture, Japan, the world's largest single nuclear power station, was completely shut down for 21 months following an earthquake in 2007. [1] Erosion of the 150-millimetre-thick (5.9 in) carbon steel reactor head at Davis-Besse Nuclear Power Plant , in Oak Harbor, Ohio, USA , in 2002 ...
The plant with seven units is the largest single nuclear power station in the world, which now again is shut down due to the Fukushima accident. [47] 0: 1 Dec 2009: Hamaoka, Japan: Leakage accident of radioactive water. 34 workers were exposed to radiation: 0: Mar 2011: Fukushima Dai-ichi, Japan: The world's second INES 7 accident.
The world's first nuclear reactor meltdown was the NRX reactor at Chalk River Laboratories, Ontario, Canada in 1952. [22] The worst nuclear accident to date is the Chernobyl disaster which occurred in 1986 in the Ukrainian SSR, now Ukraine.
A nuclear meltdown (core meltdown, core melt accident, meltdown or partial core melt [2]) is a severe nuclear reactor accident that results in core damage from overheating. The term nuclear meltdown is not officially defined by the International Atomic Energy Agency [ 3 ] or by the United States Nuclear Regulatory Commission . [ 4 ]
Nuclear experts have warned of the risk of damage to the plant's spent nuclear fuel pools or its reactors. Cuts in power needed to cool the pools could cause a disastrous meltdown.
The Windscale fire resulted when uranium metal fuel ignited inside plutonium production piles; surrounding dairy farms were contaminated. [33] [34] The severity of the incident was covered up at the time by the UK government, as Prime Minister Harold Macmillan feared that it would harm British nuclear relations with America, and so original reports on the disaster and its health impacts were ...
A massive earthquake and tsunami caused nuclear meltdowns at the Fukushima Daiichi plant in 2011. The company, Tepco, has been pumping in water to the plant to cool down the reactor's fuel rods.
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 ...
