  3. 3. Fuel Pellet (3.5%) Uranium Fual Pellet A typical pellet of uranium weighs about 7 grams (0.24 ounces). It can generate as much energy as 3.5 barrels of oil, 17,000 cubic feet of natural gas, or 1,780 pounds of coal
  4. 4. Fusion Powers the Sun
  5. 5. Nuclear Fission Nuclear fission is the process of splitting the nucleus of a heavy atom (target nucleus) into two or more lighter atoms (fission products) when the heavy atom absorbs or is bombarded by a neutron. A few radionuclides can also spontaneously fission.

  13. 13. Method of Nuclear Power PWR (Pressurized Water Reactor) In the Pressurised Water Reactor the core is surrounded by water and is enclosed in a very thick steel pressure vessel. The water, under high pressure, serves as both coolant and moderator. It is circulated to a heat exchanger(steam generator) where water in a separate circuit is turned into steam.
  14. 14. A Nuclear Reactor Core Method of Nuclear Power
  15. 15. Republic of Korea PWR (Pressurized Water Reactor)
  16. 16. PHWR (Pressurised Heavy Water Reactor) Figure is shows the Canadian-designed and built CANDU reactor. Instead of being in a pressure vessel, the fuel is in a number of pressure tubes within a reactor vessel called a calandria. Pressurised water or heavy water flows through the tubes and conveys the heat to a steam generator. Heavy water under low pressure fills the calandria, surrounding the pressure tubes, and acts as moderator. Method of Nuclear Power
  17. 17. BWR(Boiling Water Reactor) The BWR is characterized by two-phase fluid flow (water and steam) in the upper part of the reactor core. Light water (i.e., common distilled water) is the working fluid used to conduct heat away from the nuclear fuel. The water around the fuel elements also &quot;thermalizes&quot; neutrons, i.e., reduces their kinetic energy, which is necessary to improve the probability of fission of fissile fuel. Fissile fuel material, such as the U-235 and Pu-239 isotopes, have large capture cross sections for thermal neutrons. Method of Nuclear Power
  18. 18. BWR(Boiling Water Reactor) Method of Nuclear Power
  19. 19. Steam Turbine Method of Nuclear Power
  20. 20. Boiling Water Reactor Nuclear Power Plant A reactor behaves in a similar manner. As the reactor water is boiled, its volume increases, and the steam escapes at high speed through the outlet piping. The piping is designed so the steam strikes the cups on the turbine wheel; the wheel spins and its shaft turns the copper coil in the electrical generator. Method of Nuclear Power
