  2. File:PWR nuclear power plant diagram.svg - Wikipedia

    en.wikipedia.org/wiki/File:PWR_nuclear_power...

    English: Nuclear reactor: pressurized water type. Water is heated through the splitting of uranium atoms in the reactor core. The water, held under high pressure to keep it from boiling, produces steam by transferring heat to a secondary source of water. The steam is used to generate electricity.

  4. Control rod - Wikipedia

    en.wikipedia.org/wiki/Control_rod

    1943 Reactor diagram using boron control rods. Control rods are inserted into the core of a nuclear reactor and adjusted in order to control the rate of the nuclear chain reaction and, thereby, the thermal power output of the reactor, the rate of steam production, and the electrical power output of the power station.

  5. Reactor pressure vessel - Wikipedia

    en.wikipedia.org/wiki/Reactor_pressure_vessel

    A reactor vessel head for a pressurized water reactor. This structure is attached to the top of the reactor vessel body. It contains penetrations to allow the control rod driving mechanism to attach to the control rods in the fuel assembly. The coolant level measurement probe also enters the vessel through the reactor vessel head.

  6. Nuclear reactor safety system - Wikipedia

    en.wikipedia.org/wiki/Nuclear_reactor_safety_system

    A reactor protection system is designed to immediately terminate the nuclear reaction. By breaking the nuclear chain reaction, the source of heat is eliminated.Other systems can then be used to remove decay heat from the core.

  7. RBMK - Wikipedia

    en.wikipedia.org/wiki/RBMK

    Schematic diagram of an RBMK Schematic side view of the layout of an RBMK reactor core The reactor hall and piping systems of the RBMK reactor. The reactor pit or vault is made of reinforced concrete and has dimensions 21.6 m × 21.6 m × 25.5 m. It houses the vessel of the reactor, which is annular, made of an inner and outer cylindrical wall ...

  8. Nuclear fuel cycle - Wikipedia

    en.wikipedia.org/wiki/Nuclear_fuel_cycle

    A number of reactor designs, like the Integral Fast Reactor, have been designed for this rather different fuel cycle. In principle, it should be possible to derive energy from the fission of any actinide nucleus. With a careful reactor design, all the actinides in the fuel can be consumed, leaving only lighter elements with short half-lives ...

  9. Head (vessel) - Wikipedia

    en.wikipedia.org/wiki/Head_(Vessel)

    Vessel dished ends are mostly used in storage or pressure vessels in industry. These ends, which in upright vessels are the bottom and the top, use less space than a hemisphere (which is the ideal form for pressure containments) while requiring only a slightly thicker wall.
