In order to be useful in sustaining a reaction,the neutrons in a fission reactor must be

C)accelerated.
D)decelerated.

Question

Quizplus · Accepted Answer

Neutrons must be slowed down or decelerated in order to sustain a reaction in a fission reactor. This is because fast-moving neutrons are less likely to collide with and split the atomic nuclei in the reactor fuel. By slowing the neutrons down to thermal energies, they become more likely to cause fission and sustain the reaction.
