Moderator materials

Moderator materials are substances used in nuclear reactors to control the rate of nuclear fission. They work by slowing down fast neutrons produced during the split of uranium or other fissile materials, making these neutrons more likely to cause further fissions. Common moderator materials include water, heavy water, and graphite. They are essential for maintaining a sustained and controlled chain reaction, allowing the reactor to produce energy safely and efficiently. In simple terms, moderators act as moderators in a conversation, helping to keep the reaction steady and controlled.
