There was a naturally occurring nuclear reaction in a uranium ore deposit in Oklo, Gabon some 2 billion years ago. The reaction generated heat for more than a hundred thousand years with a potential of a meltdown.
In recent history the Santa Susana Field Lab had reactor meltdown in 1959
EBR-I in Idaho had a meltdown on November 29, 1955. There were probably other meltdowns at the Idaho Reactor Test Site earlier in other test reactors (probably a good idea for a FOIA request).

When year and where did the wrost nuclear accident occura nuclear meltdown?
NRX was a heavy water moderated, light water cooled, nuclear research reactor at the Canadian Chalk River Laboratories, which experienced one of the world's first major reactor accidents on 12 December 1952. The reactor began operation on 22 July 1947 under the National Research Council of Canada, and was taken over by Atomic Energy of Canada Limited (AECL) shortly before the 1952 accident. The accident was cleaned up and the reactor restarted within two years. NRX operated for 45 years, being shut down permanently on 8 April 1993[3]. It is currently undergoing decommissioning at the Chalk River Laboratories site.

What are the economic disadvantages of nuclear power?
Disadvantages of Nuclear Power:· Nuclear Power generates radiation, which can be harmful or even fatal to infected people.· A nuclear meltdown can occur which will release massive amounts of radiation into the community.· Extremely radioactive nuclear waste is produced by nuclear power plants. This stuff can't be just thrown out. The US plans to move all its nuclear was to an underground dump by the year 2010. Currently it is stored in the plants.· Nuclear waste dumps can spontaneously combust without warning.· Nuclear reactors only last for about forty to fifty years, so where they are extremely productive, they break down and are costly to replace.· There are international dangers too. Some reactors produce plutonium which can be used to make nuclear weapons. If the whole world were to use these, they would have unlimited access to nuclear weapons.
In 1945 what happened with nuclear weapons?
1945 was the first year that a Nuclear bomb was successfully tested then used in combat.
