![]() Understand the conservation laws that apply to nuclear reactions. Fission uses as fuel, fossil fuels, mainly Uranium-235 or Plutonium-239, and recently Thorium-232.All these nuclear fuels are limited resources, while fusion uses hydrogen that is a renewable resource. 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. Compare and contrast nuclear fission and nuclear fusion. ![]() And that is just if two neutrons create fission reactions each round. First off is the difference between fusion and fission Nuclear fusion is taking two atoms and combining them in to one atom, while nuclear fission takes one. Of course, each time fission occurs, more energy will be emitted, further increasing the power of the atomic reaction. \): When a slow neutron hits a fissionable U-235 nucleus, it is absorbed and forms an unstable U-236 nucleus. One fission will produce two atoms, the next round of fission will create four atoms, the third round eight atoms, and so on. ![]()
