Question

Why hevy water is used in fission thn water?

Answer 1

Heavy water is used in certain types of nuclear reactors, where it acts as a neutron moderator to slow down neutrons so that they are more likely to react with the fissile uranium-235 thanwith uranium-238, which captures neutrons without fissioning. ... They functioned with neither enriched uranium nor heavy water.

Answer 2

Answer:

• Heavy water can help keep such a chain reaction going.

• As each uranium atom breaks apart, it shoots out neutrons that can go on to split other atoms.

• But the neutrons are much more likely to trigger new fission events if they are slowed down.
