a) Moderator:
In the context of atoms and molecules, a moderator is a substance used in nuclear reactors to slow down fast-moving neutrons produced by nuclear fission. The slowing down of these neutrons increases the likelihood of their interaction with fissile material (like uranium or plutonium), thus sustaining the nuclear chain reaction. Generally, moderators are materials with low atomic mass, such as water, heavy water (deuterium oxide), or graphite. When fast neutrons collide with the nuclei of these lighter atoms, they lose kinetic energy, becoming thermal neutrons, which are more effective in causing nuclear reactions.

b) Breeder reactor:
A breeder reactor is a type of nuclear reactor designed to produce more fissile material (such as ___ ____ __________ __________ _____ _________ ________ ______ __________.
