In a nuclear reactor, the main purpose of the moderator is to
- A Initiate the fission process by giving away its neutron
- B Slow down the fast neutrons
- C Cool down the excess of heat generated in the reactor
- D Absorb excess of neutrons and control the reaction rate
Answer & Solution
Correct Answer
(B) Slow down the fast neutrons
Step-by-step Solution
Detailed explanation
The moderator helps slow down the neutrons produced by fission to sustain the chain reaction. Control rods can then be inserted into the reactor core to reduce the reaction rate or withdrawn to increase it.
