In this lesson, find out what each one is and how they work to create nuclear energy. Lesson Overview: Commercial nuclear power plants operate using fission. Fission vs fusion reaction. 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. In both fusion and fission, nuclear processes alter atoms to generate energy.
Reaction 5. You can check out the difference between the two in this infographic below. In a nuclear reactor, a neutron is absorbed into a nucleus (typically uranium-235). Main Difference – Nuclear Fission vs Fusion. They yield millions of times more energy than other sources through nuclear reactions.

When the nuclei undergo fission (the splitting of an atom) or fusion (when two atoms combine) tremendous amounts of energy is released. A nuclear weapon (also called an atom bomb, nuke, atomic bomb, nuclear warhead, A-bomb, or nuclear bomb) is an explosive device that derives its destructive force from nuclear reactions, either fission (fission bomb) or from a combination of fission and fusion reactions (thermonuclear bomb).Both bomb types release large quantities of energy from relatively small amounts of matter.

In both reactions, the atoms are altered, and the end products would be completely different from the initial reactants.Nuclear fusion releases a higher energy than that of nuclear fission.
Large amounts of energy are released when fusion occurs. The word fission means "a splitting or breaking up into parts" (Merriam-Webster Online, www.m-w.com). Unlike nuclear fission, the nuclear fusion reaction in a tokamak is an inherently safe reaction. In this lesson students will watch a video and read in order to be able to explain the difference between fission and fusion. Fission and fusion are two words that sound very much alike, but they're actually very different! Nuclear fission releases heat energy by splitting atoms. Being a nuclear reaction that turns one element into another without destroying the atoms (nuclear fission destroys the atoms to generate energy, while nuclear fusion turns one element into a heavier one with the release of clean energy in the process), nuclear fusion can be easily controlled and stopped when necessary. It may seem counterintuitive that energy is released both when atoms split and when they merge. Difference between Fission and Fusion. The energy harnessed in nuclei is released in nuclear reactions. Nuclear Fission and Fusion. Credit: Duke Energy. Extremely high temperatures (on the order of 1.5 x 10 7 °C) can force nuclei together so the strong nuclear force can bond them. Download this infographic on fission and fusion or the individual fact cutouts below. In physics, an action always has an equal but opposite reaction. "Nuclear fusion power could be a reality in 10 to 15 years." The thorium wildcard With the goal of clean energy in mind, the focus isn't only on nuclear fusion. They are opposing processes, and therefore very different. Nuclear fusion is a process in which atomic nuclei are fused together to form heavier nuclei. Fission was discovered in 1938 by the German scientists Otto Hahn, Lise Meitner, and Fritz Strassmann, who bombarded a sample of uranium with neutrons in an … Graphic by Sarah Harman | U.S. Department of Energy Fission vs Fusion Infographic (Long) Nuclear fission is the splitting of a large atomic nucleus into smaller nuclei. Fission and fusion are two physical processes that produce massive amounts of energy from atoms. What’s the difference between fission and fusion? Nuclear fission is the splitting of a heavy nucleus into two lighter ones. It was in 1952 that the U.S. government tested the first fusion bomb, but fusion reactors, as of May 2011, are still impractical. Nuclear fusion and nuclear fission are chemical reactions that take place in the nucleus of an atom. These reactions release a very high amount of energy.
