Question : In nuclear reactors, moderators are used to?
Option 1: Accelerate neutrons
Option 2: Absorb the neutrons
Option 3: Slow down the neutrons.
Option 4: Generate neutrons
Correct Answer: Slow down the neutrons.
Solution : The answer is to Slow down the neutrons .
Moderators are employed in nuclear reactors to delay or reduce the speed of fast-moving neutrons. The fundamental job of moderators is to increase the likelihood of nuclear fission by lowering neutron kinetic energy , making them more effective in sustaining a nuclear chain reaction.
