Reactor coolant

Definition

Reactor coolant is a fluid used in nuclear reactors to remove heat from the reactor core and transfer it to electrical generators and the environment. It plays a crucial role in maintaining safe operating temperatures within the reactor.

5 Must Know Facts For Your Next Test

1. The primary function of reactor coolant is to transfer heat away from the reactor core.
2. Common types of reactor coolants include water, liquid metal, and gas.
3. In Pressurized Water Reactors (PWRs), water acts as both a coolant and a moderator.
4. Coolant must maintain its properties under high radiation and temperature conditions.
5. A loss-of-coolant accident (LOCA) can lead to overheating and potential meltdown if not managed properly.

Moderator:

A material that slows down neutrons in a nuclear reactor, increasing the likelihood of fission.

Pressurized Water Reactor (PWR): A type of nuclear reactor where water is used as both a coolant and moderator, maintained at high pressure to prevent boiling.

Loss-of-Coolant Accident (LOCA): An event where the coolant is lost from the cooling system, potentially leading to overheating and meltdown.
