Nuclear meltdown derived from a 1967 report by a group of nuclear physicists, headed by W. K. Ergen. In the event, Lapp’s hypothetical nuclear accident was cinematically adapted as "The China Syndrome" (1979). Nuclear meltdown A nuclear meltdown (core melt accident or partial core melt) is a severe nuclear reactor accident that results in core damage from overheating. The term "nuclear meltdown" is not officially defined by the International Atomic Energy Agency or by the Nuclear Regulatory Commission. However, it has been defined to mean the accidental melting of the core of a nuclear reactor, and is in common usage a reference
Nuclear power U.S. Army experimental nuclear power reactor at the National Reactor Testing Station in eastern Idaho, derived from the Borax Boiling water reactor(BWR) design, it first achieving operational criticality/connection to the grid in 1958. In 1961 During a manual removal of a control rod, it underwent a steam explosion and meltdown, which killed its three operators. The event was eventually rated at 4 on the seven-level INES scale. The 's liquid metal cooled reactor accident in 1968 resulted in 9 fatalities and 83 other injuries. The total global installed nuclear capacity initially rose relatively quickly, rising from less than 1 gigawatt
