The function of moderators in nuclear reactor is to _________________?
Correct answer: A. Slow down the secondary neutrons
- A. Slow down the secondary neutrons
- B. Absorb the secondary neutrons
- C. Control the chain reaction
- D. None of these
Explanation
A moderator reduces the energy of fast neutrons produced during fission, increasing the likelihood that they will cause further fissions. It does not primarily absorb them or directly regulate the chain reaction.
