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.

Why have no fusion reactors been built yet?
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.
What are some reasons why no practical fusion reactor has yet been developed?
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.
Why have fusion reactions 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. 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.
Is fusion energy expensive?
"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.
Is nuclear fusion used as an energy source in power plants?
Nuclear power plants use controlled atomic fission to generate electricity. Atoms of the fissile material are split and part of their mass is converted to energy in addition to neutrons being ejected from the nucleus. These neutrons impact other atoms within the fissile material which then release further energy and more neutrons. The reaction is controlled by absorbing most freed neutrons with material so an uncontrolled chain reaction doesn't occur like the atom bomb used in WWII. The energy released produces heat (and radiation) which heats liquid into steam turning turbines connected to electric generators to make electricity. The highly radioactive spent fuel is a dangerous waste product that must be warehoused for many lifetimes. Conversely, the simplest type of nuclear fusion, which may become a reality this century, converts hydrogen atoms into helium atoms and produces no radioactive waste products.
Why have no fusion reactors been built yet?
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.
Does nuclear fusion occur in nuclear reactor?
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.
Are there more fast breeder or thermal nuclear reactors?
Most nuclear reactors are thermal-neutron reactors. A few fast breeder reactors have been built, but not many.
Where has nuclear fusion been used?
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.
What are some reasons why no practical fusion reactor has yet been developed?
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.
What step was taken to insure the nuclear reactor was safe in chernobyl?
The RBMK reactors at Chernobyl were probably the most unsafe reactors ever designed and built. They should never have been built.
What are the reactors of nuclear fusion?
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

What are ideal places for fission and fusion?
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
What are the disadvantages of nuclear fusion for electricity?
It has not been developed enough to make this clear
What is a major disadvantage of using nuclear fusion reactors?
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.
What solutions have been found for nuclear energy?
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.
