Nuclear Power Plants MCQs

1.Identify the pair that represents secondary nuclear fuels from the options below.

Thorium-232 and Uranium-238Uranium-233 and Plutonium-239Uranium-233 and Plutonium-238None of the above

2.Identify the incorrect statement from the following:

In a heterogeneous reactor with solid fuel, the fuel is arranged systematically within the moderator.Thermal neutrons possess energies approximately equal to 0.025 eV.Neutrons classified as fast typically have energies exceeding 1000 eV.A fast reactor operates by utilizing a moderator to slow down neutrons.The primary disadvantage of using water as a coolant in nuclear reactors is its high vapor pressure.
