Answers

Answered by snehakumari1952005

Answer:

The moderator of a nuclear reactor is a substance that slows neutrons down. In traditional nuclear reactors, the moderator is the same thing as the coolant: it's water! When fast neutrons strike the hydrogen atoms in H2O, they slow down a lot (like a billiard ball striking another).
