chain reactor

A chain reactor provides electricity for a large city.

Definition

Noun: A chain reactor is a type of nuclear reactor in which a controlled, self-sustaining nuclear fission chain reaction is used to generate energy. It is designed to maintain a steady rate of fission, where neutrons released from splitting atoms induce further fissions, producing heat that is then converted into electricity.

Usage

The term "chain reactor" specifically describes the core mechanism of energy production in a nuclear power plant. It emphasizes the self-sustaining chain reaction process. - The scientists worked to maintain the critical state in the chain reactor. - A chain reactor must be carefully controlled to prevent a runaway reaction.

Advanced Usage
  • "to operate a chain reactor": To manage and control the nuclear fission process within the reactor.
    • Only highly trained personnel are qualified to operate a chain reactor.
  • "chain reactor core": The central part of the reactor where the fission chain reaction takes place.
    • The fuel rods are housed in the chain reactor core.
Variants and Related Words
  • Nuclear reactor (n): The broader term for any device used to initiate and control a nuclear chain reaction. A chain reactor is a specific type of nuclear reactor.
  • Fission reactor (n): A synonym often used interchangeably with "chain reactor," highlighting the nuclear fission process.
Synonyms
  • Atomic pile: An early, less common term for a nuclear reactor.
  • Nuclear pile: Similar to "atomic pile," referring to the structure that sustains a chain reaction.
Related Phrases
  • Chain reaction (n): The self-propagating series of nuclear fissions. This is the fundamental process that a "chain reactor" controls.
    • The goal is to sustain a stable chain reaction within the chain reactor.
  • Reactor core (n): The region containing the nuclear fuel where the chain reaction occurs.
  • Critical mass (n): The minimum amount of fissile material needed to maintain a nuclear chain reaction, a key concept for chain reactor operation.
