What is the major disadvantage of using nuclear fusion reactors?

We don't have nuclear fusion reactors. We have not been able to sustain a controlled fusion reaction for more than a brief moment in time, and of more than a small amount of power.
Only the Sun and stars have controlled fusion reactions, and Hydrogen bombs have uncontrolled fusion reactions.
The problem is in maintaining the extremely high temperature and pressure required to sustain a fusion reaction, while at the same time containing the plasma that results from it. It is so hot that no container will hold it. We can build magnetic "bottles" so to speak, but the enormous flux required to do that requires super magnets, and that requires super-conductors and super-cold temperatures. Placing a super-hot plasma flow within the boundaries of a super-cold magnet is just not something we have accomplished yet.
We are working on it, but, barring any stupendous discovery, I think controlled fusion reactors are at least 50 or a 100 years away.

What is a major disadvantage of using nuclear fusion reactors?
Today these installations are not surely controlled.
How does URANIUM contribute to the ecomomy of the US?
Uranium is the major component of the nuclear fuel in the nuclear energetic reactors. Also United States use uranium for weapons.
What are drawbacks of nuclear fusion?
It takes a huge amount of pressure and temperature to get started and maintain stably. Fusion experiments kept going so far are highly inefficient and take more energy to do than they produce.
What are the uses of nuclear reactors?
Updated AnswerNuclear energy manifests itself as:radiation from radioactive decay of radioactive isotopes. In this regards, nuclear has a wide variety of uses in medical diagnosis & treatment , in agriculture, and in industry, or asthermal energy coming from nuclear fission. In this regards it is used for desalination of saline water, or for electric power production, or for driving marine ships or submarines.Answergenerally the genration of nuclear power source is very important for the developement of the nation in every aspect.BUT the major use is the power production , since our country lack in power sources ........
Is the nuclear reaction that takes place in a nuclear electrical generating plant exothermic?
I would imagine it is since the goal of an electric plant is to give off energy, and exothermic reactions release entergy. Both fusion and fission, the two major nuclear reactions, are exothermic.

What is the major source of energy the sun now produces?
Nuclear fusion.

Nuclear fusion.
Where does France stand as a nuclear power?
France is one of the major nuclear powers in the world today. Both in strategic defence and by far the largest in the production of electricity through nuclear reactors.

What is the major problem with fusion reactions as an energy source?
Problem on nuclear fusion is upon confinement of reaction in earth atmosphere. Nuclear fusion required very high temperature to initiate the reaction. Sustaining reaction is not easy. It is likely the earliest nuclear fusion will be available commercially by 2050. It is a little far future for the current energy crisis would reach it peak around 2040.
Major drawback to the use of nuclear power?
A major drawback to the use of nuclear power is that it produces radioactive waste. This waste can pollute water sources and kill organisms.
