![]() Fusion reactions are not easily controlled, and it is expensive to create the needed conditions for a fusion reaction. 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. Some scientists believe there are opportunities to do so. While fission is used in nuclear power reactors since it can be controlled, fusion is not yet utilized to produce power. The high-speed neutrons that are ejected become projectiles that initiate other fission reactions, or chain reactions. This resulting energy is then used to heat water in nuclear reactors and ultimately produces electricity. This splits the target nucleus and breaks it down into two smaller isotopes (the fission products), three high-speed neutrons, and a large amount of energy. During the process, a neutron is accelerated and strikes the target nucleus, which in the majority of nuclear power reactors today is Uranium-235. These neutrons are accelerated and then slammed into the unstable isotope, causing it to fission, or break into smaller particles. Fission takes place when a large, somewhatunstable isotope (atoms with the same number of protons but different number of neutrons) is bombarded by high-speed particles, usually neutrons. ![]() Just as cell’s divide, in fission an atom splits into smaller particles. Both fission and fusion alter atoms to create energy, but what is the difference between the two?įission, a term coined by scientists LIse Meitner and Otto Frisch, is named after the term “binary fission” in biology to describe cell division. The foundation of nuclear energy is harnessing the power of atoms by splitting apart, a process called fission, or combining them, called fusion. Inside the sun, fusion reactions take place at very high temperatures and enormous gravitational pressures. Look up during the day to see one of the most powerful examples of a nuclear reactor: the sun. "This includes public engagement and energy justice, diverse workforce development, a regulatory framework that engenders public trust and supports timely deployment, market identification, attracting investment and commercialization partners, export controls, nuclear nonproliferation, cybersecurity, international coordination, building critical supply chains and manufacturing capabilities, and waste disposition," Hsu said.Inside the sun, fusion reactions take place at very high temperatures and enormous gravitational pressures Department of Energy, said in a Senate hearing last month. Hsu, lead fusion coordinator in the Office of the Undersecretary for Science and Innovation at the U.S. "We must also prepare the path broadly for fusion commercialization, going well beyond R&D," Dr. Scientists have already managed to produce fusion reactions, but not without using more energy to trigger the process than they were able to produce through it.Īssuming scientists are able to achieve "net energy" - producing more energy than they use to create the fusion reaction - other things will still need to fall in place for fusion to become a secure, viable energy source for the world. It is also a byproduct of the nuclear fission process used in power plants around the world today. Tritium, which does not exist abundantly in nature, could potentially be produced by a reaction between fusion-generated neutrons and lithium.
