Nuclear fusion reactors do not exist yet as we don't know how to build them. All nuclear reactors are nuclear fission reactors.
Some advantages of using a fusion reactor to produce electricity are the abundance of fuel sources like hydrogen isotopes, minimal greenhouse gas emissions, high energy output, and inherently safe operation with no risk of runaway reactions.
Fusion reactors produce energy by fusing atoms together, similar to the process that powers the sun, whereas fission reactors split atoms. Fusion reactions in reactors have the potential for abundant fuel supply with deuterium and lithium, low radioactive waste, and enhanced safety due to the inherent characteristics of the fusion process. Additionally, fusion reactions do not generate long-lasting radioactive waste like fission reactions, making them potentially more sustainable in the long term.
In a fission reactor which has been operating at a steady power level, on shutdown the fission reactions stop at once, but the radioactivity of the fission products in the fuel still produces thermal energy. This is about 6.5 percent of the previous power level immediately, dropping to about 1 percent after 1 hour. In the case of fusion, there are no fission products so this comparison does not exist, in fact if fusion reactors can ever be made, this is one of the advantages over fission reactors.
Plenty of cheap fuel, and no radioactive waste.
You must realise that any claimed advantages are based on scientists predictions, and to some extent wishful thinking, as it is not even determined in engineering terms how a nuclear fusion plant could be built, what materials could be used, and how the heat would be extracted. However ever since fusion was proposed, scientists have been pointing out that it would produce much less radioactivity than fission does, and this is true, there would not be the spent fuel containing very highly active fission products that fission produces. There would be activation of structures in the plant due to the neutron irradiation coming from the plasma undergoing fusion. There are also consequences from needing to produce the tritium fuel, which is a dangerous substance to human health. So it all depends on future progress with ITER and further test rigs, but at the moment it is academic since it is very unlikely to happen within this century.
explain how a fusion reactor would be similar to a fission reaction
no
solar is a billion times better.
The reactor(s) at Chernobyl are fission reactors, and fission of fuel and fission products following the fire and the overheating of the core melted it down.

Fusion is the combining of two atoms to make one, fission is the splitting of an atom to make two.

Fusion power is the power generated by the nuclear fusion processes. Fusion power is a primary area of researc in plasma physics. For example, the sun is a natural fusion reactor.
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.
Plenty of cheap fuel, and no radioactive waste.
In my understanding, this is because a fusion reactor reacts deuterium to produce helium, which is not radioactive, whereas a fission uses uranium or plutonium, for example, which may react to form various radioactive isotopes. A fusion reactor may contain small quantities of tritium, in which case a radioactive isotope of hydrogen may be produced, but given that the majority of reactions occurring involve solely the deuterium, there is less radioactive waste produced.
