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.
Serious nuclear power plant accidents include the Fukushima nuclear disaster (2011), the Chernobyl disaster (1986), the Three Mile Island accident (1979), and the SL-1 accident (1961). [11] Nuclear power accidents can involve loss of life and large monetary costs for remediation work.
Soviet submarine K-19 reactor accident 1961, July 4 More than 30 people were over-exposed to radiation when the starboard reactor cooling system failed and the reactor temp rose uncontrollably. Emergency repairs ordered by the captain successfully cooled the reactor and avoided meltdown, but exposed the workers to high levels of radiation. [17] 8
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.

September 30, 1999 – Tokaimura nuclear accident, nuclear fuel reprocessing plant, two fatalities. [9] August 9, 2004 – Mihama Nuclear Power Plant accident. Hot water and steam leaked from a broken pipe. The accident was the worst nuclear disaster of Japan up until that time, excluding Hiroshima and Nagasaki. Five fatalities. [9]
