How Nuclear Reactor Control Rods Work and Why Rare Earth Elements Matter
Modern nuclear control rods provide rapid, precise reactivity control, allowing operators to insert or withdraw absorbers within seconds to manage power and execute emergency scrams. Rare‑earth elements such as gadolinium and samarium serve as high‑cross‑section burnable absorbers in fuel pellets, flattening reactivity over the fuel cycle. These elements also support high‑temperature magnets used in rod‑position sensors and drive mechanisms. The supply chain is dominated by China, which processes about 85% of global rare‑earth concentrates, creating strategic risk for nuclear utilities.
