A metal alloy that protects fuel rods in nuclear reactors
  • noun
  • Specialized
: zircaloy
  • The cladding for nuclear reactor fuel rods is made of zircaloy due to its strength and durability.
  • Zircaloy-4 alloy
  • zircaloy tubes

Examples

  • Without the water, they may suffer a fire when the zircaloy cladding reaches over 2000 degrees F and spontaneously reacts with oxygen in the air.

Etymology

The word zircaloy is a modern name made from the metal zirconium and the word alloy, which means a 'metal mix'. So zircaloy literally means a 'zirconium metal mix', which explains why it is the zirconium-based alloy used to cover fuel rods in nuclear reactors.
