![]() This is why fusion is still in the research and development phase – and fission is already making electricity. Department of Energy Fission vs Fusion Infographic-revised-01.zip CutOuts. Fusion: What's the Difference Download this infographic on fission and fusion or the individual fact cutouts below. The reasons that have made fusion so difficult to achieve to date are the same ones that make it safe: it is a finely balanced reaction which is very sensitive to the conditions – the reaction will die if the plasma is too cold or too hot, or if there is too much fuel or not enough, or too many contaminants, or if the magnetic fields are not set up just right to control the turbulence of the hot plasma. Office of Nuclear Energy Infographic: Fission vs. The test, dubbed ‘Ivy Mike’, had a yield of 10.4 megatons 450 times more powerful than the fission bomb detonated over Nagasaki. Unlike nuclear fission, the nuclear fusion reaction in a tokamak is an inherently safe reaction. The still greater energy potential of nuclear fusion was demonstrated seven years later when a fission bomb was used to initiate fusion reactions in the world’s first demonstration of a thermonuclear device. ![]() In conventional nuclear power stations today, there are systems in place to moderate the chain reactions to prevent accident scenarios and stringent security measures to deal with proliferation issues. Here, we discuss how the International Atomic Energy Agency has shaped the field and the events that have produced fusion’s global signature partnership. ![]() This chain reaction is the key to fission reactions, but it can lead to a runaway process resulting in nuclear accidents. The result of the instability is the nucleus breaking up, in any one of many different ways, and producing more neutrons, which in turn hit more uranium atoms and make them unstable and so on. Department of Energy Fission vs Fusion Infographic-revised-01. A nuclear fusion energy technology is a technology that produces energy through the process of nuclear fusion. It is triggered by uranium absorbing a neutron, which renders the nucleus unstable. Download this infographic on fission and fusion or the individual fact cutouts below. Niggol Seo, in The Behavioral Economics of Climate Change, 2017. Fission and chain reactionsįission is the nuclear process that is currently run in nuclear power plants. Fusion reactors mimic the nuclear process inside the sun, smashing lighter atoms together to turn them into heavier ones and releasing vast amounts of energy along the way. Both reactions release energy which, in a power plant, would be used to boil water to drive a steam generator, thus producing electricity. However, fusion is combining light atoms, for example two hydrogen isotopes, deuterium and tritium, to form the heavier helium. In fission, energy is gained by splitting heavy atoms, for example uranium, into smaller atoms such as iodine, caesium, strontium, xenon and barium, to name just a few.
