Developing technology to harness nuclear fusion as a source of energy for heat and electricity generation is the subject of ongoing research, but whether or not it will be a commercially viable technology is not yet clear because of the difficulty in controlling a fusion reaction. Fusion is the source of energy in the sun and stars. Even though each fission reaction yields about ten times the energy of a fusion reaction, the energy per kilogram of fission fuel is less, because there are far. Nuclear energy can also be released in nuclear fusion, where atoms are combined or fused together to form a larger atom. Nuclear fusion is the process of fusing multiple atoms together, while nuclear fission is the process of breaking them apart. This reaction is controlled in nuclear power plant reactors to produce a desired amount of heat. This process is called a nuclear chain reaction. These neutrons continue to collide with other uranium atoms, and the process repeats itself over and over again. More neutrons are also released when a uranium atom splits. What did the experiment at NIF accomplish It crossed a critical threshold for fusion where the energy that the fusion reaction generated 3.15 million joules exceeded the 2.05 megajoules. 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. During nuclear fission, a neutron collides with a uranium atom and splits it, releasing a large amount of energy in the form of heat and radiation. Both fission and fusion are nuclear reactions that produce energy, but the processes are very different. All nuclear power plants use nuclear fission, and most nuclear power plants use uranium atoms. Download a free PDF for nuclear fission and fusion difference to clear your doubts. The primary fuel used is Hydrogen isotope. The primary fuel used during Fission in power plants is Uranium. In Fusion, extremely high amount of energy is required to bring two or more atoms to combine with each other. In nuclear fission, atoms are split apart, which releases energy. Learn more about nuclear fission and fusion difference in detail with notes, formulas, properties, uses of nuclear fission and fusion difference prepared by subject matter experts. With fusion, the phenomenon is reversed: two light atoms combine to form a larger atom. Fusion is the energy of the stars and the reason our sun burns bright. Fusion is a nuclear reaction in which two or more nuclei atoms combine to form a larger nucleus.
