Answer:

Fission reactors are used to generate electricity, but fusion is not yet practical enough to be used

Explanation:

The nuclear fission process a nucleus of a 235U heavy atom is bombarded with neutrons and disintegrates into two smaller nuclei, releasing some neutrons and energy, which can be used to generate electricity.

In the process of nuclear fusion the union of light nuclear produces heavier nuclei, this process is still in the experimental phase and there are no commercial reactors for the production of electricity.

Checking the different statements is correct :

Fission reactors are used to generate electricity, but fusion is not yet practical enough to be used

Nuclear fission reactors are used to generate electricity, but fusion is not yet practical enough to be used.

What are nuclear reactions?

Nuclear reactions are reactions which involves changes in the nucleus of atoms which produces large amounts of energy known as nuclear energy.

The two types of nuclear reactions are:

  • Nuclear fusion and
  • Nuclear fission

Nuclear fission reactors are used to generate electricity, but fusion is not yet practical enough to be used.

Therefore, nuclear reactions produce energy by means of fission reactions.
