List of nuclear power accidents by country

[1] The French Atomic Energy Commission (CEA) has concluded that technical innovation cannot eliminate the risk of human errors in nuclear plant operation.

[1][5] 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.

[7] The 1979 Three Mile Island accident in Pennsylvania was caused by a series of failures in secondary systems at the reactor, which allowed radioactive steam to escape and resulted in the partial core meltdown of one of two reactors at the site, making it the most significant accident in U.S.

The accident occurred at the Chernobyl Nuclear Power Plant after an unsafe systems test led to a series of steam explosions that destroyed reactor number four.
