After scientists conducted more experiments, they found that nuclear power was a clean and efficient way to produce energy. "The first nuclear reactor was created on December 2, 1942, at the Uni- versity of Chicago by Enrico Fermi." (Editors of Scientific America, 1995). The discovery of nuclear energy provided a new source of en- ergy and an alternative to the use of natural resources: such as coal, oil, water, and wood. At the same time, nuclear energy could be used in a destructive way, such as the atomic bomb. At that time, the discovery of a new source of energy was a very significant event. By using a small amount of plutonium and uranium, two radioactive elements, an enormous amount of energy could be ob- tained. Nuclear energy can be produced in two different ways, by the fission or fusion process. Fission involves the breaking up of heavier atoms into lighter atoms. In a nuclear fission reaction, two smaller nu- clei of approximately equal mass are formed from the splitting of a large nucleus. This splitting of an atom produces a large amount of en- ergy. This process is the most common form of nuclear power. Fusion is a method that combines lighter atoms into heavier atoms. In a nuclear fusion reaction, a large nucleus is formed from two small nuclei joined together. Fusion reactions are difficult to produce because of the repul-
