Heavy water and __________ is one of the substance used as moderator in reactors.
- A Sea water
- B Titanium
- C Graphite
- D Cobalt
Answer & Solution
Correct Answer
(C) Graphite
Step-by-step Solution
Detailed explanation
A moderator's job in a nuclear reactor is to slow down fast-moving neutrons so they can effectively cause further fission. Graphite and heavy water are ideal for this because they have light nuclei that can absorb the kinetic energy of neutrons through collisions without…
