Is fission or fusion used in nuclear power plants? which is more powerful? which is a cleaner source of energy? why do you think one used as an energy source in power plants while the other is not?

Nuclear fission

Explanation:

Nuclear fission is used in energy plants. In physics and physical sciences, nuclear fission reaction occur when there is a split in the nucleus of an atom. The process releases one or more neutrons in the case of the fissioning of a nucleus with a high mass number. A neutron with a suitable energy interacts with a nucleus to induce fission.

The fusion results in a generation of high heat and is difficult to control. Hence the limited use if not at all,

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.
