Power Generation by Nuclear Power Plant

1. Power Generation by Nuclear Power Plant To understand how electrical energy is generated from nuclear energy in a nuclear power plant, along with the functions of each component involved in the process.

2. Theory A nuclear power plant works on the principle of nuclear fission — the process in which the nucleus of a heavy atom (like Uranium-235 or Plutonium-239) splits into two or more lighter nuclei when bombarded with neutrons, releasing a huge amount of heat energy . This heat is used to produce steam , which drives a steam turbine connected to an alternator (generator) , producing electricity . The working of a nuclear power plant is similar to a thermal power plant , except that the boiler (furnace) is replaced by a nuclear reactor , which produces heat through nuclear fission instead of burning fuel.

6. Kakrapar Nuclear power plant The Kakrapar Atomic Power Station (KAPS) is located in Gujarat, India, and features both older, operational 220 MW reactors and newer, indigenously designed 700 MW Pressurized Heavy Water Reactors (PHWRs). Units 3 and 4 of the newer 700 MW reactors have successfully achieved commercial operation, making them a significant part of India's goal for energy independence through domestically built nuclear power technology.
