The only place in which nuclear FUSION takes place is in stars (the sun included), and in the detonation of a hyndrogen bomb. If you are asking about nuclear FISSION (an entirely different process), restate the question.

Where has the process of nuclear fusion been occurring for over four billion years?
In the Sun's interior
Which one of these two process is still used today Nuclear Fission or Fusion?
Fission. Fusion has never been used on Earth, except for nuclear weapon tests.
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.
Why dont we use nuclear fusion in nuclear power plants?
Because no one has been able to produce a continuous fusion reaction so far.
What are the disadvantages of nuclear fusion for electricity?
It has not been developed enough to make this clear

What process occurs in a controlled fusion reaction?
In a controlled fusion reaction, a process of nuclear fusion occurs, but it is controlled, so that it does not grow uncontrollably, to become, for example, a thermonuclear bomb. Note: This has not been accomplished yet.
If scientists can utilize nuclear fission to create energy such as in nuclear electric power plants why can't they use nuclear fusion?
Because nothing to safely hold the process in has been developed yet.
What are the Application of nuclear fusion?
Nuclear fusion has been used for nuclear transformation, which is the production of new materials by fusion, and for the type of specific type of transformation called nuclear synthesis, which is the production of materials not normally found in nature. It has been used in nuclear bombs, specifically fusion bombs or hydrogen bombs. There is hope that nuclear fusion can be used to provide power for generation of electricity, though this has not yet been achieved in a practical system. There is a link below to an article on nuclear fusion.
Describe the energy of nuclear fusion?
Nuclear fusion has not yet been achieved on Earth but it is the process by which the un and stars are believed to gain their energy. At the moment nuclear reactors use nuclear fission, which is the splitting of radioactive nucleii. Nuclear fussion is the combining, or the fusion, of atoms which would release much much more energy. Many scientists believe that this is the way we need to go to solve the energy crisis.
Nuclear fusion opperratin?
Nuclear fusion on earth has not been achieved in any way that could produce power, but experiments continue.
What are two reasons that people have not been able to use nuclear fusion as an energy source?
Nuclear fusion is unsure now at industrial scale.

Is nuclear a renewable energy?
Nuclear fusion is not renewable. It requires hydrogen nuclei as an energy source, and once these have been used in fusion they are not naturally replenished. In fact, fusion power has a very high energy change, rendering it near impossible to reverse the process. A star, for example, is powered by nuclear fusion, and will eventually die out due to a lack of hydrogen.
Which stars do not have nuclear fusion occurring in their core?
All stars "burn" by the process of nuclear fusion. When fusion has been completed, the star dies. That can occur in several different ways and the interested party could look into the topic of stellar evolution. Neutron stars, black holes and white dwarfs are examples of end stages of stellar evolution. Some stars never really reach the stage of fusion and such large objects are called brown dwarfs. If Jupiter were not a planet, it might be deemed a brown dwarf.
