Fusion reactors have not been developed and built yet because it is a complex and challenging process to control and sustain nuclear fusion reactions at a scale that is practical for energy production. Scientists are still working on overcoming technical and engineering obstacles to make fusion power a viable and reliable source of energy.
Fusion reactors have not been built yet because it is challenging to create and sustain the extreme conditions required for nuclear fusion to occur, such as high temperatures and pressures. Scientists are still working on developing the technology to make fusion reactors a viable and practical energy source.
Challenges in controlling plasma at extremely high temperatures, finding materials that can withstand harsh conditions, and high energy costs required for research and development are some reasons why practical fusion reactors have not been developed yet. Additional factors include the complexity of the technology, regulatory hurdles, and the need for international collaboration.
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. If we were to perfect the technology and use it commercially, it would probably give the earth unlimited technology as it would have an energy output similar to that of a star.
"Expensive" is relative, since we have been unable to sustain a controlled break-even fusion reaction yet. So far, we have spent 10 billion euros attempting to do so, with another 100 billion budgeted in the next 50 years. If the theoretical concepts hold true, however, fusion power could well be the cheapest power on the planet.
Fusion reactors require extremely high temperatures and pressures to recreate the energy-producing reactions that occur in the sun. Containing and controlling these conditions in a stable and efficient manner has been a major challenge. Additionally, the technology needed to sustain a controlled fusion reaction at a scale large enough for practical energy production is still under development.

No. "Reactors" contain fission reactions. No useful way of containing fusionon an industrial scale outside the laboratory has been developed yet.Edit: Tomak fusion reactors currently produce 10 times the energy that is put into them. The historical increase into the gain of fusion reactors has bettered the increase of capacity of DRAMs. The only reason that that it "isn't out of the laboratory" is because when you build a fusion reactor, it is usually called a laboratory.
Most nuclear reactors are thermal-neutron reactors. A few fast breeder reactors have been built, but not many.
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.

The RBMK reactors at Chernobyl were probably the most unsafe reactors ever designed and built. They should never have been built.
In nature, the stars. Man made reactors have not been successful yet, but the most promising are the tokamak types, which are toroidal chambers where a plasma containing the fuel in gaseous form is heated to a very high temperature to produce fusion. You can read more in Wikipedia

It has not been developed enough to make this clear
Fission takes place in nuclear reactors, which are useful to produce electricity. Fusion has not yet been harnessed on earth, so the only place it happens is in stars
One major disadvantage of using nuclear fusion reactors is the challenge of controlling and sustaining the extreme conditions required for fusion reactions to occur, such as high temperatures and pressures. Additionally, the technology is still in the developmental stage and has not yet been deployed on a large scale for energy production.
Solutions? The most effective way to use nuclear power yet found is the PWR, with BWR a close second. These work well, but more advanced solutions will be developed in the future, like fast breeder reactors and fusion.
