Established in 1943 as part of the Manhattan Project, the site was home to the Hanford Engineer Works and B Reactor, the first full-scale plutonium production reactor in the world. Plutonium manufactured at the site was used in the first atomic bomb, which was tested in the Trinity nuclear test, and in the Fat Man bomb used in the bombing of ...
A re-creation of the experiment involved in the 1945 incident. The sphere of plutonium is surrounded by tungsten carbide blocks acting as neutron reflectors.. The demon core was a sphere of plutonium that was involved in two fatal radiation accidents when scientists tested it as a fissile core of an early atomic bomb.
A major accident might result in loss of life and severe health effects, and Groves was concerned that even a minor one could disrupt vital war production – particularly of aluminum – or require evacuation of the Manhattan Project's isotope separation plants. But spreading the Oak Ridge facilities over a larger area would involve the ...

Over thirty small communities were removed from Soviet maps between 1958 and 1991. [67] (INES level 6) [32] October 1957: Windscale fire, UK. Fire ignites a "plutonium pile" (an air cooled, graphite moderated, uranium fuelled reactor that was used for plutonium and isotope production) and contaminates surrounding dairy farms.
On July 16, 1945, Manhattan Project staff conducted the first-ever nuclear test, which, according to the National Park Service, spread radioactive fallout over an area approximately 250 miles long ...
The project was a key part of the Manhattan Project, the United States nuclear weapons development program during World War II. Its purpose was to convert natural (not isotopically enriched) uranium metal into plutonium-239 by neutron activation , as plutonium is simpler to chemically separate from spent fuel assemblies, for use in nuclear ...
The public will get a chance to tour B Reactor, the main attraction of the Manhattan Project National Historical Park’s Hanford site, before it is shut down for repairs later this year.. The ...
