The advantages of breeder reactors is that the neutrons from the uranium + plutonium expended in the reaction are used to generate more fissile material (plutonium and in some designs other fissionable transuranic elements). In other words you are getting two thing out of one. This allows nearly complete use of the uranium that was mined instead of just the 0.7% of it that is uranium-235 that other reactors are limited to using, reducing the waste of depleted uranium.
The disadvantages of breeder reactors are:
Some disadvantages of fusion reactors include the high cost of development and construction, the challenge of containing and controlling the extremely hot plasma required for fusion reactions, and the production of radioactive waste that needs to be managed. Additionally, fusion reactors are not yet commercially viable and it may take many more years of research and development before they can be widely implemented.
Advantages:
1) the neutrons from the uranium+plutonium expended in the reaction are used to generate more fissile material (plutonium). Thus you kind of get a two-for-the-price-of-one deal going there.
Disadavantages
1) has to be cooled with liquid sodium
2) even more complicated and expensive than a normal reactor
3) potential for misuse of plutonium by terrorists.
They can produce more fissile fuel than they consume, from U238 or thorium. However the fuel cycle has to involve chemical treatment of the irradiated material, which is a costly process with undesirable radioactive by products. At present there is no great incentive to develop such reactors but this could change in the future.
they create less radioactive waste.
There are many ways that a Nuclear Fission Reactor is used, 1) To produce Plutonium or Tritium for Bombs. 2) To generate Electricity.
A Nuclear Reactor generates Electricity that is clean and Cost efficient. But the Main disadvantage is That a steam or hydrogen-oxygen explosion can cause a lot of environmental impacts.
they don't exist yet. they're building one, but construction hasn't started yet.
A breeder reactor produce more fissile material than consume. I suppose that very serious disadvantages doesn't exist.
Nuclear fusion reactors do not exist yet as we don't know how to build them. All nuclear reactors are nuclear fission reactors.
Zero, there are no practical fusion reactors. All existing prototype designs for fusion reactors take far more energy input to make them run than they generate.
Plenty of cheap fuel, and no radioactive waste.
Fusion power is not yet practical for large-scale power generation due to challenges in creating and sustaining the extreme conditions needed for fusion to occur, such as high temperatures and pressures. Additionally, current fusion reactors are still in the research and development phase, with commercial-scale reactors not yet operational. There are also significant technical and cost challenges that need to be overcome before fusion power can be a viable energy source.
Fusion reactions have not been practical for widespread use in nuclear reactors because they require extreme temperatures and pressures to achieve sustained reactions. Overcoming these technical challenges has proven difficult and costly. Research is ongoing to develop and harness fusion as a sustainable energy source, but commercial fusion power plants are not yet operational.
No. Our reactors are fission reactors. We haven't yet mastered fusion reactors for power.
Yes, stars are fusion reactors.
Well, fusion bombs are, but fusion reactors should not be (if we can build them).
Nuclear fusion reactors do not exist yet as we don't know how to build them. All nuclear reactors are nuclear fission reactors.
Nuclear fusion is used as a potential source of clean and abundant energy in research and experimental reactors, such as ITER. It has the potential to produce electricity with fewer greenhouse gas emissions than fossil fuels, and it generates energy by fusing atomic nuclei together at extremely high temperatures. However, commercial fusion power plants are not yet operational.
There are fission and fusion reactors. However, at present (2016) there is no commercial fusion reactor which can produce more energy than is required to operate it.
Zero, there are no practical fusion reactors. All existing prototype designs for fusion reactors take far more energy input to make them run than they generate.
There are fuel pellets and laser beams inside fusion reactors. But note that we have not build a successful one. The technical problems are overwhelming at this point.

yes. If they ever perfect hydrogen fusion reactors, then maybe someone will have to come up with a clearer description, but until now, they are the same.
Nuclear fusion has been primarily used in research facilities and laboratories to study its potential for generating energy. It has not yet been harnessed for practical energy production on a commercial scale, although there are ongoing efforts to develop fusion reactors for this purpose.
