This is why scientists are trying to take advantage of fusion by working on cold fusion. In 1939, scientist began experiments, and one year later Enrico Fermi built the first nuclear reactor. Energy Input VS Energy Output Extremely high levels of heat are necessary in order to fuse the two nuclei of the atoms together. In fusion, two lighter atomic nuclei collide to form a heavier nucleus, releasing an astronomical amount of heat that can be used to generate electricity. Scientists continue to work on controlling nuclear fusion in an effort to make a fusion reactor to produce electricity. Fusion power vs. nuclear fission The other half of nuclear energy — the well-established nuclear fission — has proven itself to be a commercially viable alternative to fossil fuels. 3. The energy released by the process of fusion is around 3-4 times much greater than that of the energy liberated by the process of fission. These reactions release a very high amount of energy. At first, the reactor thermal output will be higher than the nuclear fusion power, as it also includes the heat released during the tritium production from lithium in the blanket and the recirculated power of the fuel heating. Instead of fusing lighter atoms together, it focuses on splitting them apart and is responsible for about 20% of all the electricity in the United States. In both reactions, the atoms are altered, and the end products would be completely different from the initial reactants. Naturally, scientists are trying to bring about a scenario whereby there is a net energy output surplus. They are opposing processes, and therefore very different. Nuclear fission releases heat energy by splitting atoms. Nuclear fusion and nuclear fission are chemical reactions that take place in the nucleus of an atom. While fission is splitting of a heavy, unstable nucleus into two lighter nuclei, fusion is the process where two light nuclei combine together releasing vast amounts of energy. Olivia is a Graduate in Electronic Engineering with HR, Training & Development background and has over 15 years of field experience. It is normally fission that is used in nuclear power reactors as it can be controlled. The reaction releases huge amount of energy. The word fission means "a splitting or breaking up into parts" (Merriam-Webster Online, www.m-w.com). In order for fusion to occur, you need a temperature of at least 100,000,000 degrees Celsius. It is a nuclear reaction that is just the opposite of fission as instead of splitting, here two light nuclei are joined together under extreme heat and pressure. Fusion releases the energy of the strong force (much stronger at short distances than the EM force) when the small pieces are captured and held into one nucleus. The word fusion means "a merging of separate elements into a unified whole". Nuclear Energy Nuclear energy can also be separated into 2 separate forms: nuclear fission and nuclear fusion. Energy is required to create the very high temp. Fusion is said to have taken place when two light nuclei combine together, releasing energy in the process. Though both nuclear reactions release huge amounts of energy, there are differences between the two types of nuclear reactions that will be highlighted in this article. All rights reserved. This is the same process that powers the sun and creates huge amounts of energy—several times greater than fission. Nuclear fission is a nuclear reaction in which the nucleus of an atom splits into smaller parts (lighter nuclei). This energy can be released in two different ways known as fission and fusion reactions. All rights reserved. Fission is the splitting of a heavy, unstable nucleus into two lighter nuclei, and fusion is the process where two light nuclei combine together releasing vast amounts of energy. The foundation of nuclear energy is harnessing the power of atoms. 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. Along with this, an enormous amount of energy is released, which is several times the amount produced from fission. Fission vs. Fusion – What’s the Difference? Fusion has the potential to deliver much more power than fission, but without the long-lasting radioactive waste. But it is a method only in experimental stages at present. Fusion takes place when two low-mass isotopes, typically isotopes of hydrogen, unite under conditions of extreme pressure and temperature. Fission is used in nuclear power reactors since it can be controlled, while fusion is not utilized to produce power since the reaction is not easily controlled and is expensive to create the needed conditions for a fusion reaction. Both fission and fusion are nuclear processes by which atoms are altered to create energy, but what is the difference between the two? Atoms of Tritium and Deuterium (isotopes of hydrogen, Hydrogen-3 and Hydrogen-2, respectively) unite under extreme pressure and temperature to produce a neutron and a helium isotope. Fission, which is the energy source in current nuclear power stations, involves splitting an atom’s nucleus. Both nuclear fusion and fission release very large and substantial amounts of energy and both share the same energy source, which is the atom itself. Nuclear fusion could be considered the opposite of what nuclear power plants use today, fission, the splitting of a nucleus of an atom into two or more smaller parts. Whether the reaction is exothermic or not, it is dependent on the binding energy of resulting nuclei.
