Of the following, which does not belong to a nuclear reactor?
Answer
The correct answer is C: A mechanism to reduce CO2 emission. A nuclear reactor consists of a reaction chamber (core) where fission occurs, a heat exchanger to transfer heat to a working fluid, and a turbine driven by steam to generate electricity. Nuclear reactors do not emit CO2 during fission, so they do not require…
A.A turbine
B.A heat exchanger
C.A mechanism to reduce CO2 emission✓ Correct
D.A reaction chamber
Explanation
A nuclear reactor consists of a reaction chamber (core) where fission occurs, a heat exchanger to transfer heat to a working fluid, and a turbine driven by steam to generate electricity. Nuclear reactors do not emit CO2 during fission, so they do not require a mechanism to reduce CO2 emissions. Therefore, a 'mechanism to reduce CO2 emission' is not a component of a nuclear reactor.
