The Economist

Successive scandals, such as the failure to report coolant leaks, have since further undermined confidence in the industry.Such difficulties make building nuclear reactors more lengthy and thus expensive.

The Economist

As its name suggests, the VHTR is designed to run at very high temperatures, heating the coolant to around 950{degree}C, compared with 315{degree}C for a standard PWR, making it more thermally efficient.Like the SCWR, the VHTR will require the development of new materials.

The Economist

Although the helium coolant presents fewer corrosion problems than supercritical water, creating core materials and fuel casings that can withstand the high temperatures involved is a daunting task.

The Economist

(The vast majority of French cars are, after all, still using the old coolant).

The Economist

In May they will begin refrigerating the coolant to up to -40ºC.

The Economist

It was only a matter of time before some of them would have failed, and discharged significant quantities of radioactive coolant.

The Economist

It has a once-through uranium cycle, but instead of water it uses graphite as the moderator and helium gas as the coolant.

Expert writing Tips

Best practice

When describing technical specifications, be precise about the type of "coolant" used (e.g., water, ethylene glycol, or specialized fluids) to avoid ambiguity.

Common error

While both terms relate to cooling, "coolant" is typically used in contexts where heat is absorbed and transferred (e.g., engines), whereas "refrigerant" refers to substances used in refrigeration cycles where phase changes are involved.

Linguistic Context

The primary grammatical function of "coolant" is as a noun. It refers to a substance, typically a fluid, that is used to remove heat from an object or system. Ludwig AI confirms this usage through various examples.

FAQs

How is "coolant" used in a sentence?

"Coolant" is used as a noun to describe a substance that removes heat, as in, "The engine requires regular checks of its coolant levels."

What is another word for "coolant"?

Alternatives for "coolant" include "cooling agent", "heat transfer fluid", or "refrigerant fluid" depending on the context.

What is the purpose of using "coolant" in an engine?

The purpose of using "coolant" in an engine is to prevent overheating by absorbing and dissipating heat, maintaining optimal operating temperatures.

Can I use water instead of "coolant"?

While water can be used as a "coolant", it lacks the properties of commercial coolants, such as antifreeze and corrosion inhibitors. Therefore, it's generally not recommended unless in emergency situations. Consider the context whether "cooling agent" may be more appropriate.
