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. Nuclear energy can also be released in nuclear fusion, where atoms are combined or fused together to form a larger atom. Typically, when uranium 235 nucleus undergoes fission, the nucleus splits into two smaller nuclei (triple fission can also rarely occur), along with a few. This reaction is controlled in nuclear power plant reactors to produce a desired amount of heat. When Uranium-235 absorb a neutron, a fission (or. When a neutron passes near to a heavy nucleus, for example uranium-235 (U-235), the neutron may be captured by the nucleus and this may or may not be followed by fission. This process is called a nuclear chain reaction. Nuclear plants use a certain kind of uranium, Uranium-235, as fuel because its atoms are easily split apart. 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. 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. All nuclear power plants use nuclear fission, and most nuclear power plants use uranium atoms. The fission reaction in U-235 creates fission products such as Ba, Kr, Sr, Cs, I, and Xe, as shown in the above equation, with atomic masses distributed around 95 and 135. Two forms (isotopes) of uranium are found in nature, uranium-235 and. In nuclear fission, atoms are split apart, which releases energy. In nuclear fission, energy is released when the nuclei of atoms are split apart.
