![]() ![]() About 180 MeV of energy is produced in the fission of an. Meanwhile, fusion occurs only under extreme temperature and pressure.Īnother difference between fission reactions and fusion reactions is that the energy from fission can be controlled but it cannot be controlled in fusion. In fission reactions, a heavy nucleus is split into two lighter fragments and two or three neutrons. In fission, the chain reaction happens due to the interaction between neutrons and fissile isotopes. Though fusion produces more energy and it is less dangerous than fission reactions, fusion reactors are yet to be developed. In fact it is more costly to develop the conditions that are needed for a fusion reaction.įission happens because of chain reaction, and no chain reaction happens in fusion. Fusion also produces more energy and it may be three to four times greater than fission reactions. When comparing the radioactive waste produced by these two reactions, the radioactive waste that comes with fusion is very low than what is produced by a fission reaction. But if fission reaction goes out of control, a nuclear melt down can happen which can cause the emission of radioactive participles ion in larger quantities. Scientists from more than 50 countries have been trying to recreate it on Earth since the 1960s. Results: The main result is that fission reactions are always spontaneous (G < 0) since a lot of energy is released in the form of heat and the system moves spontaneously towards a more disordered state. The maximum damage of a fusion reaction is only the vaporization of anything in the vicinity of the reaction. Nuclear fusion is the process which gives the Sun its energy. ![]() If the reaction goes out of control in fusion, the whole process stops automatically as it cools down, which means that radio active participles do not spread out. Fusion requires tremendous energy to conjoin two nuclei.įusion reaction is considered to be more environmental friendly to produce nuclear energy. In terms of energy requirement for the two processes, fission only needs a low energy for splitting the atom, whereas fusion takes place only under massive energy. At the center of each atom is a nucleus (the plural of which is nuclei), where neutrons and protons are bound in close proximity together. They join together only if the active force between them is capable of overcoming the electrostatic force that binds it. Fission and fusion All matter is composed of atoms: incredibly small structures that house different combinations of three particles, known as protons, neutrons, and electrons. Fusion happens when two nuclei come very close together. Fission requires large Critical Mass and a slow neutron to initiate the process. Fission happens with heavy elements like Uranium and fusion evolves lighter elements.įission and fusion happen in different conditions. While fusion takes place in nature like stars, fission normally does not occur in nature. Though energy is released during both fission and fusion reactions, the main difference is that fission is the process of splitting of an atom into two or smaller particles and fusion is the fusing or joining together of two or more smaller atoms to form a larger one. Fission and fusion are two different types of reactions in which large quantities of energy are released. ![]()
