Question

In a nuclear power plant, excess heat is:

A. released into the air
b. reused by the nuclear reactor
c. absorbed and removed by water
d. used to power turbines and generators

Answer 1

Answer: In a nuclear power plant, excess heat is C. absorbed and removed by water.

Step-by-step explanation:

In any power plant, heat from the burning of fossil fuel or from the fission of nuclear fuel is removed by water. Water passes through the system and absorbs heat. Then it is returned to its original source. Thermal effects refers to the effect this heat will have on the source body of water.

Answer 2

Option (D)

Step-by-step 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).
