![]() ![]() ![]() Developing technology to harness nuclear fusion as a source of energy for heat and electricity generation is the subject of ongoing research, but whether 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. Nuclear fission and fusion By Pratimesh pathak Pratimesh Pathak 4K views11 slides. The energy released by fission is a million times greater than that released in chemical reactions but lower than the energy released by nuclear. Chapter 22.4 : Nuclear Fission and Nuclear Fusion Chris Foltz 4.6K views8 slides. The main difference between these two processes is that fission is the splitting of an atom into two or more smaller ones while fusion is the fusing of two or more smaller atoms into a larger one. This reaction is controlled in nuclear power plant reactors to produce the desired amount of heat. nuclear reactors Yogesh Sinkar 34.2K views33 slides. This process is called a nuclear chain reaction. Fusion, on the other hand, occurs when two or more light-weighted atoms fuse together, producing a larger and heavier atom. 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. These benefits are countered by the difficulty in harnessing fusion. Fusion offers an appealing opportunity, since fusion creates less radioactive material than fission and has a nearly unlimited fuel supply. All nuclear power plants use nuclear fission, and most nuclear power plants use uranium atoms. Some scientists believe there are opportunities to do so. ![]() In nuclear fission, atoms are split apart, which releases energy. ![]()
