  1. Nuclear reactor - Wikipedia

    Just as conventional thermal power stations generate electricity by harnessing the thermal energy released from burning fossil fuels, nuclear reactors convert the energy released by controlled nuclear …

  2. NUCLEAR 101: How Does a Nuclear Reactor Work? - Department of …

    May 19, 2025 · Nuclear reactors are the heart of a nuclear power plant. They contain and control nuclear chain reactions that produce heat through a physical process called fission.

  3. Nuclear Power Reactors - World Nuclear Association

    Jan 7, 2026 · In a nuclear power reactor, the energy released is used as heat to make steam to generate electricity. (In a research reactor the main purpose is to utilize the actual neutrons produced …

  4. Nuclear Reactors: Principle, Types, Uses, Examples, Risks

    Jul 4, 2025 · What Is a Nuclear Reactor? A nuclear reactor was built with the aim of running, directing, and carrying out a nuclear chain reaction, which causes massive amounts of energy getting …

  5. Nuclear reactor | Definition, History, & Components | Britannica

    Dec 30, 2025 · In a nuclear reactor the chain reaction is maintained at a controlled, nearly constant level. Nuclear reactors are so designed that they cannot explode like atomic bombs. Most of the …

  6. Neutron induced fission releases energy plus extra “fast” neutrons. “Fast” neutrons are slowed down by a “moderator” such as water or graphite, allowing chain reaction to take place (rapid increase in …

  7. Nuclear Reactors 101: A Comprehensive Guide

    Jun 9, 2025 · Explore the fundamental principles of nuclear reactors and their significance in general inorganic chemistry, covering reactor types, fuel cycles, and safety measures.

  8. Nuclear reactors for dummies - by Alex Chalmers

    May 15, 2025 · In a PWR, nuclear fission heats water in a primary coolant loop kept under high pressure to prevent boiling.

  9. How a Nuclear Reactor Works | NEI

    When the reactor starts, uranium atoms will split, releasing neutrons and heat. Those neutrons will hit other uranium atoms causing them to split and continue the process, generating more neutrons and …

  10. Nuclear reactor - Energy Education

    A nuclear reactor is a system used to initiate and contain a nuclear chain reaction, and they have many useful applications. These nuclear reactions produce thermal energy through either nuclear fission …
