  • Nuclear Power for Everybody - What is Nuclear Power
    What is Nuclear Power? This site focuses on nuclear power plants and nuclear energy The primary purpose is to provide a knowledge base not only for experienced
  • Reactor Startup - Nuclear Power
    A reactor startup is a procedure, that comprises many points and changes of operational parameters and significantly differs according to certain reactor types
  • Definition, Principles Components - Nuclear Power Plant
    A nuclear power plant is a thermal power plant in which a nuclear reactor generates large amounts of heat This heat is used to generate steam (directly or via steam generator) which drives a steam turbine connected to a generator that produces electricity
  • Reactor Period | nuclear-power. com
    The reactor period, τe, or e-folding time, is defined as the time required for the neutron density to change by a factor e = 2 718 Definition of Reactor Period
  • Constantan – 45Ni-55Cu – Properties and Uses - nuclear-power. com
    In nuclear reactors, the thermocouples are positioned at preselected locations to measure fuel assembly coolant outlet temperature for use in monitoring the core radial power sharing and coolant But in this case, thermocouples must withstand neutron irradiation Thus, type E (chromel-alumel), or other special thermocouples are preferred Properties of Constantan – 45Ni-55Cu Material
  • Reactivity Coefficients – Reactivity Feedbacks - nuclear-power. com
    As the thermal power increases, moderator temperature and fuel temperature increase, causing a negative reactivity effect (from the power coefficient), and the reactor returns to the critical condition Positive reactivity must be continuously inserted (via control rods or chemical shim) to keep the power to be increasing
  • Fuel Cladding - Cladding Tube | Definition | nuclear-power. com
    Fuel cladding is the outer layer of the fuel rods, standing between the reactor coolant and fuel pellets A cladding tube is a corrosion-resistant material with a low absorption cross section for thermal neutrons, usually zirconium alloy
  • Reactor Shutdown | Condition SCRAM | nuclear-power. com
    The excore nuclear instrumentation system monitors the reactor’s power level by detecting neutron leakage from the reactor core The excore nuclear instrumentation system is considered a safety system because it provides inputs to the reactor protection system during startup and power operation
  • Gamma Rays Gamma Radiation - Nuclear Power for Everybody
    Gamma rays, also known as gamma radiation, refer to electromagnetic radiation (no rest mass, no charge) of very high energies Gamma rays are high-energy photons with very short wavelengths and thus very high frequency
  • DNB – Departure from Nucleate Boiling - nuclear-power. com
    Operation within the Nuclear Enthalpy Rise Hot Channel Factor – FNΔH limits prevents departure from nucleate boiling (DNB) during accidents limiting from DNB point of view For example, a loss of forced reactor coolant flow accident, a loss of normal feedwater flow, or an inadvertent opening of a pressurizer relief valve
