Question
The function of the moderator in a nuclear is to
- Stop chain reaction
- Absorb neutrons
- Reduce the speed of neutrons
- Reduce temperature
Hint:
The moderators are used in nuclear reactors to slow down the speed of neutrons.
The correct answer is: Reduce the speed of neutrons
- The moderators reduce the speed of neutrons.
- They are used in nuclear reactors to slow down the neutrons produced from fission.
- Water is a good example of a moderator used in nuclear reactors.
