water-cooled reactor

Thân thiện

The engineer monitors the control panel of the water-cooled reactor.

Definition

Noun: A water-cooled reactor is a type of nuclear reactor that uses water as its primary coolant to remove heat from the reactor core.

Usage

This term is a specific technical compound noun used in the field of nuclear engineering. It describes a fundamental design characteristic of a reactor system. It is typically used in technical discussions, reports, and educational materials related to nuclear power.

Examples

• The most common type of commercial power plant is a water-cooled reactor.
• Safety protocols for a water-cooled reactor must account for the maintenance of coolant pressure and flow.
• The design of a water-cooled reactor differs significantly from that of a gas-cooled or liquid-metal-cooled system.

Advanced Usage

• The term is often part of more specific classifications, such as light-water reactor (LWR) or pressurized water reactor (PWR), which are sub-types of water-cooled reactors.
• In technical comparisons, the coolant choice (water, gas, molten salt) is a key differentiator, making "water-cooled" a critical descriptor.

Variants and Related Words

• Light-water reactor (LWR): A water-cooled reactor that uses ordinary water (as opposed to heavy water) as both coolant and neutron moderator.
• Pressurized water reactor (PWR): A common type of water-cooled reactor where the coolant water is kept under high pressure to prevent boiling.
• Boiling water reactor (BWR): A type of water-cooled reactor where the coolant is allowed to boil in the core, producing steam directly to drive turbines.
• Coolant (n): The fluid used to remove heat from the reactor core.
• Reactor core (n): The central part of a nuclear reactor containing the fuel and where fission takes place.

Synonyms

• Light-water reactor (This is a near-synonym for the most prevalent type, but not all water-cooled reactors are LWRs, e.g., some use heavy water).
• Hydraulic reactor (This term is very rare and not standard; "water-cooled reactor" is the universally accepted term).

Antonyms / Contrasting Terms

• Gas-cooled reactor: A nuclear reactor that uses a gas (like carbon dioxide or helium) as the primary coolant.
• Liquid-metal-cooled reactor: A nuclear reactor that uses a liquid metal (like sodium or lead) as the primary coolant.
• Molten salt reactor: A nuclear reactor that uses a molten fluoride or chloride salt as the primary coolant and sometimes also as the fuel carrier.
