Chapter 16, Problem 12TE

Solution

To determine: The significance of the energy of fission is used in a commercial power reactor.

Answer:

The heat is produce in commercial power plants by self-sustaining chain reaction.

Explanation:

Nuclei of the atom absorb the free neutron and become unstable by releasing the neutrons. The fragment of the nuclear by fission reaction takes a large amount of energy.

The neutron collides with fuel like uranium-235, the kinetic energy of the neutron is converted into the heat energy. The process keeps on repeating, and it forms a self-sustained chain reaction.

By self-sustaining chain reaction, the heat is produced in commercial power plants. The heat is transformed into steam, and it helps to rotate the turbine for producing electricity.

Conclusion:

Therefore, the heat is produce in commercial power plants by self-sustaining chain reaction.
