After this process was completed, Ernest O. Lawrence from the university of California in Berkeley implemented a process i nvolving magnetic separation of the two isotopes. Finally, a gas centrifuge was used to further separate the Uranium-235 from the Uranium-238. The Uranium-238 is forced to the bottom because it had more mass than the Uranium-235. This Uranium was then transported to a laboratory headed by J. Robert Oppenheimer. Oppenheimer was the major force behind the Manhattan Project. He literally ran the show and saw to it that all of the great minds working on this project made their brainstorms work. He oversaw the entire project from its conception to its completion. Once the purified Uranium reached New Mexico, it was made into the components of a gun-type atomic weapon. The scientists were so confident that the gun-type atomic bomb would work that no test was conducted and it was first employed in military action over Hiroshima, Japan, on Aug. 6, 1945.
Once again the University of Chicago, under Enrico Fermi's direction built the first reactor. This led to the construction of five large reactors at Hanford, Wash., where U-238 was irradiated with neutrons and changed into plutonium. The plutonium was sent to Los Alamos.
There was a debate at Los Alamos about whether to test the new plutonium implosion' bomb before it was actually dropped. "Harvard explosives expert George B. Kistiakowsky and Oppenheimer both argued for such a test, but initially Groves was opposed. He was afraid that if the test failed, the precious plutonium would be scattered all across the countryside."(Szasz 26) Brigadier General Leslie R. Groves, the man the army placed in charge, was eventually persuaded. Hanford's plutonium production was increasing fast enough so that a test would cause little delay in time. They feared that if they dropped the untested plutonium bomb and it failed to work, "the enemy would find themselves owners of a gift' atomic weapon.
Nuclear bombs are similar to conventional bombs. ... These atoms are either split or fused to create new atoms. ... There are two main types of nuclear weapons, Atom bombs and hydrogen bombs. Atom bombs use fission as the main reaction. ... Hydrogen bombs use fusion as the main reaction meaning that the atoms are fused together. ...
The atomic bomb is a powerful, explosive nuclear weapon. ... These materials are usually separated within the bomb so that critical mass cannot be reached until the bomb is ready to explode. Once the chemical reactions within the bomb begin, the neutrons released by each reaction hit other atoms and create more fission reactions until all the material is scattered, or completely exhausted. ... The atomic bomb was first created in the early twentieth century. ... Groves designed and built the first atomic bombs, directed by J. ...
The history of the atomic bomb dates back to the early 1900's when Einstein's theory of relativity proved a basis for understanding nuclear energy and showed that the atom contained vast energy. ... They found that the split atoms released neutrons and energy. ... The hydrogen bomb uses the fusion of atoms and hydrogen to produce great heat and activity. ... First an atomic bomb explodes triggering the hydrogen and atoms. ... Then, deuterium and tritium atoms fuse. ...
By definition, a nuclear fission "is when a heavy atom is split into two atoms by a neutron hitting it." However, in nuclear technology, it is not sufficient to have a split of an atom, but rather, it is also necessary to have a continuous chain reaction that results as other neutrons are emitted by the atom. ... In addition to this, the nuclear fission of these atoms releases much more energy than that of other atoms or isotopes. ... Because there is no place for chance in exploding an atomic bomb, scientists will often increase the number of neutrons that are available to bombard the nucl...
The dropping of the atom bomb is one of the most controversial and unique events that has ever occurred in US history, and world history for that matter. ... Although the dropping of the bomb can be justified or refuted, depending in what one believes, there were indeed major political and military reasons as to why the bomb was ultimately dropped. ... Therefore, the atomic bomb would be saving numerous American lives from a rather tough invasion. ... Another political reason back in the US was that Truman was convinced that using the bomb would be a good idea. ... The dropping of the atom...
Fission is when a neutron can cause the nucleus of a uranium atom to break into two(Documentation 7). ... Uranium atoms are unusually large, so it is hard for them to hold together firmly. ... A U - 235 atom is so unstable that a blow from a single neutron is enough to split it and bring on a chain reaction. When a U - 235 atom splits, it gives off energy in the form of heat and Gamma radiation, the most powerful form of radioactivity and the most lethal. When a reaction occurs, the split atom will give off spare neutrons, causing other atoms to split, so actually, it is only necessary to ...
Three days later, the United States dropped a second atom bomb on the city of Nagasaki bringing World War II to an end. ... The discovery of the nuclear atom dates back to 1911, but its potential power was not realized until the late 1930s. The study of atoms as a weapon originated in Germany. ... Two years later, the United States replied by developing the Hydrogen Bomb, the predecessor to the atom bomb, which was 1,000 times more powerful. ... The atom bomb has left a permanent mark on the world, but it's not all bad. ...
The decision to drop the Atom Bomb created a huge impact on Americans and forever changed the way that other nations view the United States. ... Some of the main arguments in Alperovitz's book about the decision to drop the Atomic Bomb include whether or not it was really necessary, why an attack on civilians, and how does the United States justify using the Atom Bomb if they are against the notion of using chemical weapons. ... King, Commander in Chief of Naval Operations said. " I didn't like the atom bomb or any part of it." ... Atomic Bomb, or no Atomic Bomb, Japan would soon b...
