ANSWER

Why does the nuclear fusion reaction yield more energy than the nuclear fission reaction? Fission only produces more energy than it consumes in large nuclei (common examples are Uranium & Plutonium, which have around 240 nucleons (nucleon = proton or neutron)).

Why does the nuclear fusion reaction yield more energy ?

Fission only produces more energy than it consumes in large nuclei (common examples are Uranium & Plutonium, which have around 240 nucleons (nucleon = proton or neutron)). Fusion only produces more energy than it consumes in small nuclei (in stars, Hydrogen & its isotopes fusing into Helium).

Why do both fission and fusion release energy? While both fission and fusion release energy, the process and amount is very different. Fission exploits the instability of nuclei of heavy elements like uranium, which can be split using neutrons, producing fragments with a lower total mass. The difference appears as energy – courtesy of E=mc² – which is carried away by fast-moving neutrons.

Which produces more energy, nuclear fusion or nuclear fission? Elements heavier than Iron produce more energy through fission. Fission is when a large nucleus divides into smaller nuclei releasing energy. Certain elements such as Uranium-235 can be made to fission easily. So, the answer is fusion produces more energy if it involves light elements and fission produces more energy if it involves heavy elements.

Why there is more energy released in fusion than fission ?

The energy released has to do with the relative energy or binding energy per nucleon. Each fission reaction releases about 200 MeV of energy, but the initial mass is about 236 or 240 amu (after neutron capture). The fission reaction produces two new nuclei of masses about 143 and 90 amu and 2 or 3 neutrons.

Why is nuclear fusion 'stronger' than fission even though ? Because fission/fusion weapons are "staged" where the first fission core provides the energy to compress and heat the fusion fuel, the fusion stage can involve more fuel mass than the …

Why does nuclear fusion give off more energy than nuclear ? Nuclear fusion doesn't always give off energy though, production of the heavier elements actually is an endothermic reaction, it requires energy. Nuclear fission is the opposite, it is the splitting of a larger element into two smaller nuclei.

Why does the fusion reaction produce more energy than the ?

To answer this you need to look at the binding energy per nucleon graph as follows: Now lets look at fission. An example of fission is when a Uranium-235 atom is split by a neutron into a Barium-144 atom, a Krypton-89 atom and three neutrons. Now

DOE ExplainsNuclear Fusion Reactions Department of Energy? Nuclear Fusion reactions power the Sun and other stars. In a fusion reaction, two light nuclei merge to form a single heavier nucleus. The process releases energy because the total mass of the resulting single nucleus is less than the mass of the two original nuclei.

Why nuclear fusion is gaining steam – again? The main fuel for fission, Uranium-235, has 2 million times the energy per pound that oil does. Fusion may deliver up to seven times that or more . The fuel used for fission is extremely abundant.

Why only light nuclei are able to undergo nuclear fusion ? When you use heavier nuclei, they will have more protons, and so the coulombic repulsion between the nuclei will increase. The means that you need to put in more energy in order to fuse the nuclei together. Because this only detracts from the efficiency of the process, it is favorable to use lighter nuclei for nuclear fusion reactors.
