What are the disadvantages of fusion reactors?

Answer 1

The advantages of breeder reactors is that the neutrons from the uranium + plutonium expended in the reaction are used to generate more fissile material (plutonium and in some designs other fissionable transuranic elements). In other words you are getting two thing out of one. This allows nearly complete use of the uranium that was mined instead of just the 0.7% of it that is uranium-235 that other reactors are limited to using, reducing the waste of depleted uranium.

The disadvantages of breeder reactors are:

• It has to be cooled with liquid metals (e.g. sodium, potassium, NaK alloy)
• It is even more complicated and more expensive than normal reactors
• It has some potential for the misuse of the plutonium by terrorists, so will require more security

Answer 2

Advantages:

1) the neutrons from the uranium+plutonium expended in the reaction are used to generate more fissile material (plutonium). Thus you kind of get a two-for-the-price-of-one deal going there.

Disadavantages

1) has to be cooled with liquid sodium

2) even more complicated and expensive than a normal reactor

3) potential for misuse of plutonium by terrorists.

Answer 3

They can produce more fissile fuel than they consume, from U238 or thorium. However the fuel cycle has to involve chemical treatment of the irradiated material, which is a costly process with undesirable radioactive by products. At present there is no great incentive to develop such reactors but this could change in the future.

they create less radioactive waste.

Answer 4

There are many ways that a Nuclear Fission Reactor is used, 1) To produce Plutonium or Tritium for Bombs. 2) To generate Electricity.

A Nuclear Reactor generates Electricity that is clean and Cost efficient. But the Main disadvantage is That a steam or hydrogen-oxygen explosion can cause a lot of environmental impacts.

Answer 5

Some disadvantages of fusion reactors include the high cost of development and construction, the challenge of containing and controlling the extremely hot plasma required for fusion reactions, and the production of radioactive waste that needs to be managed. Additionally, fusion reactors are not yet commercially viable and it may take many more years of research and development before they can be widely implemented.

Answer 6

they don't exist yet. they're building one, but construction hasn't started yet.

Answer 7

A breeder reactor produce more fissile material than consume. I suppose that very serious disadvantages doesn't exist.
