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.
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, caused by a persistent leak of borated water The Hanford Site, in Benton County, Washington, USA, represents two-thirds of America's high-level radioactive waste by volume.
The 2011 Fukushima Daiichi nuclear disaster, the worst nuclear accident in 25 years, displaced 50,000 households after radiation leaked into the air, soil and sea. [1] Deceased Liquidators' portraits used for an anti-nuclear power protest in Geneva. This image of the SL-1 core served as a reminder of deaths and damage that a nuclear meltdown ...
Steam explosion at Mihama Nuclear Power Plant killed 4 workers and injured 7 more. 4: 9: 1 July 25, 2006: Forsmark, Sweden: An electrical fault at Forsmark Nuclear Power Plant caused multiple failures in safety systems critical for reactor cooling. 0: 100: 2 March 11, 2011: Fukushima, Japan
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 ...
Shika Nuclear Power Plant (Japan) 1999; criticality incident caused by dropped control rods, covered up until 2007. [23] Blayais Nuclear Power Plant flood (France) December 1999; Forsmark Nuclear Power Plant (Sweden) July 2006; backup generator failure; two were online but the fault could have caused all four to fail.
Nuclear aspect: the damage must be related directly to nuclear operations or materials; the event should involve fissile material or a reactor, not merely (for example) having occurred at the site of a nuclear power plant. Primarily civilian: the nuclear operation/material must be principally for non-military purposes.
Nuclear components were not installed in the weapons. While flying over the Atlantic Ocean, the aircraft experienced a loss of power. For their own safety, the crew jettisoned two bombs which were never recovered. [9] Neither of the weapons detonated. The C-124 landed later with the other weapon and the nuclear capsule.
