Questions & Step-by-Step Solutions

What is the main component of a nuclear reactor that slows down neutrons? (2023)
  • Step 1: Understand that a nuclear reactor uses nuclear fission to generate energy.
  • Step 2: Know that neutrons are particles that help sustain the fission process.
  • Step 3: Realize that fast neutrons need to be slowed down to effectively cause more fission reactions.
  • Step 4: Identify the component in the reactor that is responsible for slowing down these fast neutrons.
  • Step 5: Learn that this component is called the moderator.
