Definition

Noun: A BWR is a type of nuclear reactor where water serves the dual purpose of cooling the reactor core and slowing down neutrons (moderating). In this design, the water is allowed to boil directly within the reactor vessel, producing steam that is then used to drive a turbine for electricity generation.

Usage

The term BWR is a technical acronym used primarily in the fields of nuclear engineering and energy production. It is always capitalized.

Examples

• The power plant utilizes a BWR, which simplifies the design by eliminating the need for a separate steam generator.
• Safety protocols for a BWR differ from those of a pressurized water reactor (PWR).
• The company specializes in the maintenance of BWR systems.

Advanced Usage

• BWR technology refers to the engineering principles and systems associated with this reactor type.
• A BWR core specifically denotes the central region of the reactor where nuclear fission occurs and steam is produced.

Variants and Related Words

• Boiling Water Reactor: The full, non-abbreviated form of BWR.
• PWR (Pressurized Water Reactor): A contrasting type of nuclear reactor where the primary coolant water is kept under high pressure to prevent boiling.

Synonyms

• Boiling water reactor

Antonyms

• Pressurized water reactor (PWR)

Noun

1. a nuclear reactor that uses water as a coolant and moderator; the water boils in the reactor core and the steam produced can drive a steam turbine
