#7
What is the main function of a nuclear reactor control rod?
To absorb neutrons and regulate the reaction rate
ExplanationThe main function of a nuclear reactor control rod is to absorb neutrons and regulate the reaction rate.
#8
Which of the following is a nuclear fusion reaction?
Hydrogen-2 combining with Hydrogen-3 to form Helium-4
ExplanationThe fusion reaction involves Hydrogen-2 combining with Hydrogen-3 to form Helium-4.
#9
Which nuclear reaction powers the sun?
Fusion
ExplanationThe sun is powered by nuclear fusion reactions, where hydrogen nuclei combine to form helium, releasing energy.
#10
What is the name of the process where neutrons released in a fission reaction trigger additional fission reactions in nearby nuclei?
Chain reaction
ExplanationThe process where neutrons trigger additional fission reactions is called a chain reaction.
#11
What is a breeder reactor primarily designed to do?
Produce more energy than it consumes
ExplanationA breeder reactor is designed to produce more energy than it consumes by creating additional fissile material.
#12
What is the name of the process where energy is released when atomic nuclei combine to form heavier nuclei?
Fusion
ExplanationThe process where energy is released by combining atomic nuclei to form heavier ones is called fusion.
