Nuclear Fusion occurs when nuclei combine to make the nucleus a greater weight. In fusion reactions, a small nuclei combine and release more energy than they do in the fission reactions. In fission reactions the large nuclei split into pieces. Fusion reactions occur at high temperatures such as 40,000,000 degrees Celsius. Fusion is used to produce nuclear bombs with the high temperatures in the bombs requiring them to initiate fusion reactions. An uncontrolled fusion device is the triggering device used for setting off a hydrogen bomb. All of these processes have no use, but they are a controlled generator of power. An example of Nuclear Fusion is the sun providing the most energy whether it be direct or indirect. In the sun there are many different type of hydrogen atoms and these atoms move around at different high speeds and come together to form helium when there will be more hydrogen atoms coming together they will create a higher form of helium called helium 4. …show more content…
Fission can also release enormous amounts of energy. Nuclear fission is used with a uranium-235 in which the nucleus splits up into smaller nuclei and releases many different neutrons. Nuclear fission can also be found in Atomic bombs just like Nuclear fusion. The bombs found in fission have such a device in them in which they start an uncontrolled nuclear chain reaction. Also, fission can be controlled in such a way that energy is slowly released into Nuclear reactors which use controlled fission in order to make useful energy. Most of the energy is formed by heat when the fission reaction is controlled within a nuclear reactor. Neutron moderation and neutron absorption are the two steps for the control of fission in a nuclear
