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.

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 nuclear nonrewable or renewable?
It cold be considered renewable as in some nuclear fission reactors; called breeder reactors; more fuel could be produced than what is consumed and on the other hand uranium is one of the most abundant minerals on earth crust and water. On the other hand, fusion nuclear energy is based on unlimited resources of deuterium and tritium.
Where does fusion primarily occur?
In the sun, mostly. Humans don't built fusion reactors because we haven't yet figured out how to get more energy out of the process than we put into it. Human nuclear power generation is fission-based. Fusion also occurs in modern nuclear bombs, although this is an uncontrolled reaction and not one that can produce useful power.
How do you find elements of nuclear fusion?
In nuclear Hydrogen bomb is based on the principle of fusion. In fusion two hydrogen fuses to form one helium.
Hydrogen bomb is based on the principle of?
nuclear fusion
Will nuclear energy ever run out?
Nuclear fission may do, though with fast breeder reactors we could make use of the large amount of Uranium 238 which is not useful at present, as we only use the U235 in the present type of reactors. In the long term (probably 100 years or so) nuclear fusion may be usable, and this really would extend nuclear power for thousands of years.
What is the chemistry background of nuclear fusion?
Nuclear fusion is based on the helium nucleus synthesis from two hydrogen atoms at very high temperatures.
What percentage of nuclear power plants in operation today are based upon nuclear fusion?
None of them do.
How do stars create all elements up to iron in their core. What if your answer?
The process is called stellar nucleosynthesis and is based on nuclear fusion reactions.
If uranium was to run out what other sources are available to replace it?
AnswerProbably the nuclear fusion AnswerThere are a number of reactor designs based on using thorium, and fuel assemblies using thorium as a primary fuel can be designed and built to be used in existing reactors.
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.
