Question

Define nuclear energy power plant

Answer 1

A power plant in which the heat required to make steam and turn turbine s obtained by nuclear reactions s called a nuclear plant. The functioning of the nuclear power plant is explained below:
1.    Most of the uranium in nuclear fuel is U-238, but U-235 splits—or fissions—easily. In U-235 atoms, the nucleus, which is composed of protons and neutrons, is unstable. As the nuclei break up, they release neutrons and huge amount of energy.
2.    When the neutrons hit other uranium atoms, those atoms also split, releasing neutrons of their own, along with heat. These neutrons strike other atoms, splitting them and causing a chain reaction. When that happens, fission becomes self-sustaining.
3.    Heat produced due to fission is used to turn water into steam. The steam drives a turbine, which spins a generator to create electricity.
4.    Tremendous amount of energy is released due to fission. To control the amount of heat produced, rods are inserted among the tubes holding the uranium fuel control the nuclear reaction. These control rods trap the free neutrons thereby reducing  the number of Uranium atoms that split and hence reducing the heat produced.

Answer 2

Answer:

Nuclear energy is the energy produced when changes occur in the structure of the nuclei of atoms.
