Nuclear energy was discovered in the process of creating the atomic bomb.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.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.This splitting of an atom produces a large amount of energy.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.(LeMay, Beall, Robblee, Brower, 1996) . Fusion is mostly used to create the hydrogen bomb.
