This fact is the basis for the design of practical energy-producing fission reactors. In December 1942 at the University of Chicago, the Italian physicist Enrico Fermi succeeded in producing the first nuclear chain reaction. This was done with an arrangement of natural uranium lumps distributed within a large stack of pure graphite, a form of carbon. In Fermi's "pile," or nuclear reactor, the graphite moderator served to slow the neutrons. Nuclear fusion was first achieved on earth in the early 1930s by bombarding a target containing deuterium, the mass-2 isotope of hydrogen, with high-energy deuterons in a cyclotron.
German chemist Martin Klaproth discovered uranium in 1789 (“Outline History of Nuclear Energy” 1). Albert Einstein in 1905 discovers theory of E=mc2. In 1939 Hahn and Strassman show developments in harnessing nuclear fission (“Outline History of Nuclear Energy” 1). They showed that fission not only released a lot of energy but also released additional neutrons which led to a greater release of energy (“Outline History of Nuclear Energy” 1). British and US scientists concentrated on fission of U-235 which would lead to a new element of mass U-239 an atomic number of 94 in which would lead them to discover neptunium #93 and plutonium #94 which was based off the finding of the uranium element (“Outline History of Nuclear Energy” 1).

The Manhattan Project The Manhattan Project was the code name of the America’s attempt to construct an atomic bomb during World War II. It was named after the Manhattan Engineer District of the U.S. Army Corps of Engineers, because a lot of it’s earlier research was done in New York City. An atomic bomb is a weapon that uses the energy from a nuclear reaction called Fission for its destruction. The idea that mass could be changed into energy was predicted by Albert Einstein in the earlier part of the 1900’s. John D. Cockcroft and Ernest Walton confirmed this by experiments in 1932.
The incidents involving meltdowns have been few and far in between with a total of three occurring since the introduction of nuclear fission as a viable form for the production of electricity. All the byproducts from the production of the electricity are environmentally friendly with the exception of the depleted uranium. Using it would actually save the government and the average citizen an incredible amount of money. The dangers are few and far in between with many fail safes and precautions being implemented at the nuclear power plants. Nuclear power has the potential to completely replace the use of fossil fuel for the generation of electricity in the future.

In order to squeeze the two nuclei together, an atomic fission bomb is usually used. A fusion reaction releases about four times more energy per unit mass than a fission reaction. The United States supervised the development of the atomic bomb under the code name Manhattan Project, during World War II. The first nuclear chain reaction occurred in December 1942, at the University of Chicago. Soon after the first bomb test, atomic bombs were dropped on the Japanese cities of Hiroshima and Nagasaki in 1945.
(Wilkie) People know that despite efforts to keep control on the old Soviet stockpile and waste, terrorists are getting the plutonium and uranium needed to make nuclear weapons to kill masses of people. This is kind of the history of the nuclear & atomic bomb: (all from Williams) The first atomic bomb was thought up by Albert Einstein in the late 30's. In 1942 Enrico Fermi brought about first nuclear reaction with isotope Uranium 235. From this the Manhattan Project was brought about and took place in Los Alamos, New Mexico. Then July 16, 1945 near Alamogordo, New Mexico world's first atomic bomb was set off.

By nuclear emissions, England evades 40 million tons of carbon a year or 50% of what the cars in the nation drive. Green America, an anti-nuclear website points out the nuclear powered energy makes a lot of waste. Waste in fact is maybe the most negative thing about nuclear energy. But, through more advanced technology, waste may be able to be reduced to nothing. How a nuclear reactor works is a process called The Nuclear Fuel Cycle.
