On the other hand, the fusion chain reaction only develops or occurs in extremely high-pressure and temperature environments maintained by the energy released during the nuclear fusion process. Although controlling or bearing this kind of impact and scatter process is challenging, setting up the basic conditions is rather simple. Fission chain reactions only start when neutrons break unstable isotopes. This nuclear reaction can merge light isotopes like 2H and 3H or numerous splits of heavier isotopes like uranium 235U. The outcome is an expanding chain of reactions that can soon spiral out of control. Speaking of the nuclear fusion vs fission difference, nuclear fusion and fission are chain reactions in which one nuclear event triggers at least one further nuclear reaction, and the chain reaction often goes on indefinitely. Now, we learn about the nuclear fusion-fission difference. The uranium atoms are bombarded with neutrons, which cause them to split and release additional neutrons that strike other atoms, setting off a chain reaction that further splits atoms and releases energy from heat and radiation. In a steel reactor vessel, sealed metal cylinders containing uranium are used to split atoms in power plants. There are no carbon emissions when uranium is used in this technique instead of fossil fuels to generate heat. This energy is discharged as heat and radiation. A nuclear power plant uses the heat from boiling water into steam to move a turbine and power generators to generate electricity. What is Nuclear Fission: Nuclear fission definitionĪccording to the nuclear fission definition by scientists globally, atoms are torn apart during nuclear fission to release the nuclear energy that holds them together. The highly energetic particles can overcome their inherent electromagnetic repulsion when they collide, fusing them and releasing enormous amounts of energy. Although these temperatures are ten times higher than those at the Sun’s core, they are necessary for the process because the gravitational pressure needed for it cannot be produced by the Sun itself.Īs auxiliary heating systems raise the temperature to the necessary levels for nuclear fusion (150-300 million ☌), the energised plasma particles collide and heat up. Strong magnetic fields are required to contain this plasma because it can reach temperatures of at least 100,000,000☌. High heat and pressure cause the deuterium atoms’ electrons to break free, forming a plasma. ![]() A fusion reactor, also known as a tokamak, uses a gas, typically deuterium, an isotope of hydrogen that can be extracted from seawater. ![]() However, it has proven difficult to create the necessary conditions in fusion reactors without using more energy than is generated. Like fission power plants, nuclear fusion plants use heat from atomic reactions to heat water, produce steam, power turbines, and generate electricity. No harmful, long-term radioactive waste or greenhouse gases are produced during this process, occurring naturally in the stars’ centres like the Sun. When it comes to the nuclear fusion definition, it creates energy by coalescing atomic nuclei instead of disintegrating them (similar to fission). Nuclear Fusion vs Fission: Understanding the Terms What is Nuclear Fusion: Nuclear Fusion Definition To avoid any instances where you use the two terms interchangeably, in this post, we learn all about nuclear fusion vs fission. The U-236 nucleus then rapidly breaks apart into two smaller nuclei (in this case, Ba-141 and Kr-92) along with several neutrons (usually two or three), and releases a very large amount of energy.Īmong the products of Meitner, Hahn, and Strassman’s fission reaction were barium, krypton, lanthanum, and cerium, all of which have nuclei that are more stable than uranium-235.Nuclear fusion and fission are two terms that might sound similar, but are actually pretty different in meaning. \): When a slow neutron hits a fissionable U-235 nucleus, it is absorbed and forms an unstable U-236 nucleus. ![]()
