⚛️
Add to dictionary

reactor

[rɪˈæktər ]

Definitions

Context #1 | Noun

nuclear engineering

A reactor is a device used to initiate and control a sustained nuclear chain reaction. It is a key component in nuclear power plants, where it generates heat through nuclear fission, which is then used to produce steam that drives turbines for electricity generation.

Synonyms

fission reactor, nuclear reactor, power reactor.

Examples of usage

  • The reactor core is where the fission reaction takes place.
  • Engineers monitored the reactor's temperature closely.
  • Safety measures are crucial in reactor operation.
  • The country invested in new reactor technologies.
Context #2 | Noun

chemical engineering

In chemical engineering, a reactor refers to an apparatus or vessel where chemical reactions are conducted. This can include various types such as batch reactors, continuous reactors, or plug flow reactors, depending on the reaction requirements.

Synonyms

chemical reactor, process reactor, reaction vessel.

Examples of usage

  • The chemical reactor needs to be optimized for efficiency.
  • They designed a new reactor for high-temperature reactions.
  • The production line includes several reactors working in tandem.

Interesting Facts

Science

  • In nuclear science, a reactor allows controlled nuclear reactions to occur, producing heat used to generate electricity.
  • Most power plants use thermal reactors, where heat generated from nuclear fission is converted into energy.

Safety

  • Modern reactors are engineered with multiple safety systems to prevent accidents, such as cooling systems and containment measures.
  • The incident at the Chernobyl reactor in 1986 highlighted the critical importance of safety in nuclear energy production.

Pop Culture

  • Reactor designs and concepts have inspired countless films and shows, often depicting futuristic technologies and energy sources.
  • In video games, reactors are frequently portrayed as power sources for massive machines or weapons, adding drama to the storyline.

Technology

  • Research into fusion reactors is ongoing, aiming to replicate the sun's process for nearly limitless clean energy.
  • Small modular reactors (SMRs) are a new technology being developed to provide safer and more versatile nuclear power solutions.

Origin of 'reactor'

Main points about word origin

  • The term 'reactor' comes from the Latin word 'reactio', meaning 'a response'. It emphasizes the idea of something reacting to produce an effect.
  • It first appeared in the early 20th century, primarily linked to the field of nuclear physics and engineering.

The word 'reactor' originates from the Latin word 'reagere', which means 'to act back'. It emerged in English during the early 20th century, primarily in the context of nuclear physics. The term gained popularity with the development of atomic energy and nuclear power, particularly following World War II. In its modern usage, it encompasses both nuclear reactors and chemical reactors, reflecting advancements in technology and engineering processes. The adaptation of the word to describe devices that facilitate reactions signifies a broader understanding of both chemical principles and nuclear science.
