Any substance used to remove the heat in a nuclear reactor. Usual coolants are light and heavy water, carbon dioxide, helium and liquid sodium.

"radiator fluid," 1930, from cool (adj.) + -ant.

A substance circulating through a nuclear reactor to remove or transfer heat. Most common coolants are carbon dioxide, water (light), and heavy water.

substance, usually a liquid or gas, that reduces the temperature of a system or piece of machinery.

A substance circulated through a nuclear reactor to remove or transfer heat. The most commonly used coolant in the United States is water. Other coolants include heavy water, air, carbon dioxide, helium, liquid sodium, and a sodium-potassium alloy.

A fluid used to remove heat. See Cutting fluid.

A substance used to cool the reactor and to slow neutrons. In most nuclear power plants, water is used for cooling to keep the reactor from getting too hot and to slow neutrons down so they are more l [..]

A U.S. Department of Defense (DOD) program established in 1992 by the U.S. Congress, through legislation sponsored primarily by Senators Sam Nunn and Richard Lugar. It is the largest and most diverse [..]

Also known as "antifreeze." A mixture of water and ethylene glycol that has both a higher boiling point and a lower freezing point than plain water.

The liquid or gas used to transfer heat from the reactor core to the steam generators or directly to the turbines.

Liquid used to cool the work and tool, and to prevent rusting or corrosion; cutting fluid or grinding fluid.

A fluid circulated through a nuclear reactor to remove or transfer heat generated by the fuel elements. Common coolants are water, air and carbon dioxide.

A common term given to the numerous cutting fluids or compounds used with cutting tools to increase the tool life and to improve surface finish on the material.

Any liquid run or brushed onto the cutting edge to dissipate heat

Fluid in a sealed circuit pumped through the core of a nuclear reactor to remove thermal energy to a heat exchanger. Coolants also used to cool car engines etc.

(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

Liquid used in cooling system to dissipate engine heat.

Liquid used to carry heat away from the engine. Sometimes called antifreeze.

The mixture of water and antifreeze that picks up heat from the engine and transfers it to the air passing through the radiator.

Also called antifreeze, this combination of ethylene glycol and water protects the climate control system by dispersing excess heat and preventing parts from freezing.

A liquid used to cool and lubricate glass while it is being cut or ground with a tool to prevent hot spots or fracturing of the glass.

Fluid used to remove heat. Commonly found in an engines cooling system.

A medium, usually a fluid, which transfers heat from a object.

a fluid used to remove heat. This term has broad application in any process which generates heat as a result of frictional or combustion processes.
