Question

______ reactions generate thermal energy in a nuclear power plant as water is changed into steam

Answer 1

Fission reactions generate thermal energy

Answer 2

Answer:

Nuclear reaction.

Explanation:

Nuclear reactions are used in generation of heat in some power plants and thus those are known as nuclear power plants.

The fuel used in nuclear reactor is Uranium-235, which undergoes fussion reaction to give large amount of energy. this energy is in generation of steam in such plants.

thus nuclear fission is the main reaction in the nuclear power plants.
