Answer:
Option (D)
Explanation:
In a nuclear power plant, the reactor core is comprised of various fuel assemblies. The nuclear fission takes place inside the core of the reactor, as a result of which the heat is produced immensely. This heat energy allows the water to boil and produces stream, which forces the blades of the turbines to rotate. This continuous rotation of the turbine blades ultimately generates electricity
It is one of the efficient methods as it is cheap, creates no pollution but it produces radioactive waste which is difficult to dispose of.
Thus, the excess heat in a nuclear power plant is used to rotate the turbines and produce electricity.
Hence, the correct answer is option (D).
