The correct answer is (b), Khopoli.
A nuclear power station is a thermal power station in which the heat source is a nuclear reactor. Nuclear power plants use uranium as fuel, which is a metal that is found in nature. The uranium is enriched, which means that the amount of the isotope uranium-235 is increased. Uranium-235 is the isotope that is used in nuclear reactors.
The uranium is then placed in fuel rods, which are inserted into the reactor. The reactor is a large chamber that contains the fuel rods and the moderator. The moderator is a material that slows down the neutrons that are released when the uranium-235 atoms split. The slower neutrons are more likely to hit another uranium-235 atom and cause it to split. This process is called nuclear fission.
When a uranium-235 atom splits, it releases two or three neutrons and a large amount of energy. The neutrons then hit other uranium-235 atoms, causing them to split. This process is called a chain reaction. The chain reaction is controlled by the use of control rods. The control rods are made of a material that absorbs neutrons. When the control rods are inserted into the reactor, they absorb neutrons and slow down the chain reaction. When the control rods are removed from the reactor, the chain reaction speeds up.
The heat from the nuclear fission is used to boil water. The steam then drives a turbine, which generates electricity. The steam is then condensed back into water and returned to the reactor.
Rawatbhata, Kakrapara, and Kaiga are all nuclear power stations in India. Khopoli is not a nuclear power station. It is a town in Maharashtra, India.
