coolant coolant  /ˈku lənt/


  • (n) a fluid agent (gas or liquid) that produces cooling; especially one used to cool a system by transferring heat away from one part to another


  1. If a water-moderated reactor loses coolant there may be overheating and even an explosion, but the reaction slows down when coolant is lost.
  2. Deprived of the coolant that controls its temperature, the reactor begins melting in its own heat.
  3. Most commercial reactors guard against meltdown by ensuring that the fuel is always surrounded by circulating coolant, usually ordinary water.


  1. Vitrified Grinding Wheels incorporate abrasive bond.

    While extremely porous, Vitrium3 Bond adheres strongly to grains, allowing grinding wheels to be used safely at speeds up to 80 m/sec. Wheel form retention and radius accuracy are optimized, minimizing dressing time and wear on diamond dresser and wheel. Free flow of coolant through porous matrix results in efficient chip clearance, avoiding wheel loading and clogging. Grinding burn is ...
