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.
9 August 2004: Mihama Nuclear Power Plant accident, 4 fatalities. Hot water and steam leaked from a broken pipe (not actually a radiation accident). [95] 9 May 2005: it was announced that the Thermal Oxide Reprocessing Plant at Sellafield in the UK suffered a leak of a highly radioactive solution, into secondary containment. [96]
The Unit 1 reactor on Three Mile Island, which closed in 2019, is adjacent to the Unit 2 reactor that experienced a major nuclear power accident in 1979
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 ...

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.
TMI’s Unit 2 reactor – the site of the nation’s worst nuclear power accident in March 1979 – is independent of Unit 1 and is currently being decommissioned by its owner, Energy Solutions ...
