![]() ![]() The basic difference between nuclear fission and fusion is that in fission reaction, a heavy nucleus splits into two daughter nuclei with the emission of energy, while in nuclear fusion two lighter nuclei combine to form of heavy nuclei. ![]() Nuclear power plants exploit the process of fission to create energy. Nuclear fission and Nuclear Fusion are the Types of Nuclear Reactions. Under special circumstances (the attainment of a "critical mass") the emitted neutrons can split further atoms, which in turn bring about more splitting, producing a very fast chain reaction. While different, the two processes have an important role in the past, present and future of energy creation. In a typical reaction, an atom of uranium 235 absorbs a neutron and splits into two lighter atoms, barium and krypton, emitting radiation and neutrons. Fission is the splitting of a heavy, unstable nucleus into two lighter nuclei, and fusion is the process where two light nuclei combine together releasing vast amounts of energy. In a fission reaction, a heavy atomic nucleus is split into smaller nuclei, other particles and radiation. The two types of nuclear reactions used to produce energy are fission and fusion. Because of the principle of energy conservation the lost mass must reappear as generated energy, according to Einstein's equation E = mc². The free neutrons strike other uranium nuclei, creating a chain reaction.Ī nuclear reaction is a process in which atoms collide with other atoms and lose some of their original mass. Some of the fragments are chemical elements, such as barium or krypton, and some are free neutrons. When an incoming neutron strikes a uranium nucleus, it will break into fragments. Additionally, distinctions exist in the binding energies of the nuclear force of nuclear fusion vs nuclear fission. ![]()
