Worldwide, many nuclear accidents have occurred since the Chernobyl disaster in 1986. Two thirds of these mishaps occurred in the US.^[1] The French Atomic Energy Commission (CEA) has concluded that technical innovation cannot eliminate the risk of human errors in nuclear plant operation.
An interdisciplinary team from MIT have estimated that given the expected growth of nuclear power from 2005–2055, at least four serious nuclear power accidents would be expected in that period.^[1]
Globally, there have been at least 99 (civilian and military) recorded nuclear power plant accidents from 1952 to 2009 ……….Totaling US$20.5 billion in property damages. Property damage costs include destruction of property, emergency response, environmental remediation, evacuation, lost product, fines, and court claims.^[2] Because nuclear power plants are large and complex accidents on site tend to be relatively expensive.^[3]
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. history^{…………………………..}
