It's hard to compare the two because of the variety of fuels, and the corresponding variety of fission and fusion reactions. Currently we can't do fusion in a reactor like we can fission. That makes it hard to compare, too.
Roughly speaking, however, you'd get around 4x more energy per unit mass of fuel out of fusion. This is comparing the fusion of deuterium and tritium to Helium, with the fission of U(235) to Rb(90) and Cs(143).
Compared to the total energy in the fuel (i.e. a matter/antimatter annihilation reaction) even the fusion reaction only liberates about 0.4% of the total energy.
What else can I help you with?
How do nuclear fusion differ fundamentally from nuclear fission?
Nuclear fusion doesn't produce energy.
Which do you currently use nuclear fusion or fission?
I currently use nuclear fusion.
Where does nuclear fusion occur in a nuclear plant?
Nuclear fusion does not currently occur in nuclear plants. Nuclear plants use nuclear fission, where atoms are split to release energy. Fusion reactions, in which atomic nuclei combine to release energy, are not yet used commercially for electricity generation.
Is a nuclear power plant producing electricity an example of nuclear fusion?
No, a nuclear power plant producing electricity is an example of nuclear fission, not fusion. In nuclear fission, the nucleus of an atom is split, releasing energy, whereas in nuclear fusion, atomic nuclei combine to release energy.
What are the main reasons why nuclear fusion have not been used in nuclear reactors?
Well, scientists have been researching fusion reactors for over 50 years, but nuclear fusion is much more difficult to achieve than nuclear fission, which is what current nuclear power technology is based on. There are many reasons for this, but while there have been tests and advancements in the field, scientists have yet to a) create a sustainable and stable nuclear fusion reaction and b) create a reaction that has a greater output than input.
How is nuclear fusion an efficient energy source?
It isn't, yet.
What process produces the largest amount of energy given off by stars?
Nuclear Fusion
Is fusion chemical nuclear or mechanical?
Fusion is a nuclear reaction.
Is fusion nuclear energy or chemical energy?
Nuclear fusion produces nuclear energy
What is a nuclearfusion?
Nuclear Fusion, not to be mistaken with Nuclear Fission, is a process in which energy is created due to the merging or "fusion" of subatomic particles. The process is much more energy efficient, and produces larger quantities of energy than in a fission based process.
What causes lesser pollution - nuclear fission or fusion?
Nuclear fusion
How do nuclear fusion differ fundamentally from nuclear fission?
Nuclear fusion doesn't produce energy.
In nuclear fusion mass transforms into what?
In nuclear fusion mass transforms into energy.
Is strontium produced by nuclear fusion?
No Strontium is produced by nuclear fission not fusion.
Can americium produce nuclear fusion?
Americium was not tested to produce nuclear fusion.
Is the sun a nuclear fusion reactor?
Yes, the sun is a nuclear fusion reactor.
What is the significance of the fusion cross section in nuclear reactions?
The fusion cross section in nuclear reactions is important because it determines the likelihood of two atomic nuclei coming together and fusing to form a new nucleus. This process releases a large amount of energy and is the basis for nuclear fusion reactions, such as those that power the sun. Understanding and controlling the fusion cross section is crucial for developing sustainable and efficient energy sources.
