In an article for EnergyBiz magazine, Benjamin K. Sovacool has some figures on the number of accidents and casualties caused by the nuclear industry:
One recent study published in the May issue of Energy Policy looked at major energy accidents from 1907 to 2007. The major accidents were defined as incidents that resulted in either death or more than $50,000 of property damage. The study identified 279 incidents totaling $41 billion in damages and 182,156 fatalities, with the number of accidents peaking in the decade between 1978 and 1987, which had more than 90 accidents. In terms of cost, nuclear plants ranked first with regard to their economic damage, accounting for damages equivalent to $16.6 billion, or 41 percent of all damages during the past century.
Contrary to the industry´s claim that nuclear facilities are safe, 63 major accidents have occurred at nuclear power plants. Twenty-nine accidents have occurred since the Chernobyl disaster in 1986, and 71 percent of all nuclear accidents, that is, 45 out of 63, occurred in the United States, refuting the notion that severe accidents cannot happen within the country or that they have not happened since Chernobyl.
Using extremely conservative estimates, nuclear power accidents have also killed 4,100 people. The nuclear power accidents have involved meltdowns, explosions, fires, and loss of coolant, and have occurred during both normal operation and extreme, emergency conditions such as droughts and earthquakes.
