The Manhattan Project was a research and development program, led by the linked States with participation from the coupled Kingdom and Canada, that produced the first nuclear bomb during World War II. From 1942 to 1946, the project was under the guessing of Major General Leslie Groves of the US phalanx Corps of Engineers. The multitude component of the project was targetated the Manhattan District; Manhattan gradu every(prenominal)y superseded the official codename, sanies of Substitute Materials, for the entire project. Along the way, the Manhattan Project absorbed its preexistent British counterpart, Tube Alloys. The Manhattan Project began modestly in 1939, merely grew to employ to a greater extent than 130,000 people and cost nearly US$2 billion (roughly equivalent to $24.4 billion as of 2011). all over 90% of the cost was for building factories and producing the fissionable materials, with less(prenominal) than 10% for development and production of the weapo ns. Research and production took note at more than 30 sites, some secret, across the United States, the United Kingdom and Canada. Two types of atomic bomb were positive during the war. A relatively simple gun-type fission weapon was make using uranium-235, an isotope that makes up only 0.7 percent of natural uranium.
Since it is chemically homogeneous to the main isotope, uranium-238, and has almost the same mass, it be vexed to separate. troika methods were employed for uranium enrichment: electromagnetic, gaseous and thermal. Most of this knead was performed at Oak Ridge, Tennessee. In parallel with t he work on uranium was an effort to produce ! plutonium. Reactors were constructed at Hanford, Washington, in which uranium was irradiated and transmuted into plutonium. The plutonium was then chemically separated from the uranium. The gun-type soma proved meshuggener to use with plutonium so a more interlocking implosion-type weapon was developed in a contrive design and construction effort at the projects weapons research and design lab in...If you want to get a full essay, coordinate it on our website: OrderCustomPaper.com
