How Control Rods Keep Nuclear Power Plants Safe

  1. Control rods regulate the speed of nuclear chain reactions inside reactors.
  2. They are made of materials like boron, cadmium, or hafnium that absorb neutrons.
  3. By capturing neutrons, control rods prevent runaway fission reactions.
  4. Operators raise or lower rods to balance energy output with safety.
  5. In an emergency, rods can drop fully into the core to stop fission instantly.
  6. This rapid shutdown is known as a SCRAM, a vital safety measure.
  7. Control rods work alongside moderators to maintain reactor stability.
  8. Without them, reactors could overheat and risk meltdown.
  9. Their precision ensures nuclear power plants produce steady electricity.
  10. Control rods are a silent but critical safeguard in clean energy production.
