Some people believe nuclear power is a vital way to tackle climate change. A tomic energy has had a mixed history in the half century or so since the world s first commercial nuclear power plant opened at calder hall now sellafield in cumbria england in 1956 huge amounts of world energy have been produced from atoms ever since but amid enormous controversy. Here i am going to explain you the different types of power generating stations or power plant first let us know what is the function of a power generating station a power generating station or power plant uses various sources like hydel energy thermal energy diesel nuclear energy to produce bulk electric power here now we are going to discuss how the energy of radio.
The purpose of the water pool is to cool down the nuclear fuel and provide shielding from radiation. The nuclear fuel once used in nuclear power plant is removed from the reactor and stored in a pool of water for about 7 10 years. A nuclear power plant is a thermal power station in which the heat source is a nuclear reactor as is typical of thermal power stations heat is used to generate steam that drives a steam turbine connected to a generator that produces electricity as of 2018 the international atomic energy agency reported there were 450 nuclear power reactors in operation in 30 countries.
Steam is then generated in the heat exchanger which is used in a conventional manner to generate electric energy by means of a steam turbine. The heat released by the nuclear reaction is transported to a heat exchanger via primary coolant co 2 water etc. The schematic diagram of a nuclear power plant diagram is shown in fig.
A short summary of the process involved in nuclear power plant. The layout of nuclear power plant consists of a nuclear reactor steam generator steam turbine and condenser. In this post the nuclear power plant diagram with components used in nuclear power plant has been provided.
Enriched uranium typically is formed into 1 inch long 2 5 centimeter long pellets each with approximately the same diameter as a dime.
Nuclear plant diagram. A nuclear power plant is a thermal power station in which the heat source is nuclear reactor. Today we are going to read and learn definition working diagram layout advantages disadvantages and application of thermal power plant. At the bottom of the post you will find pdf that you can easily download. Nuclear fission of heavy elements such as uranium or thorium is carried out in a special apparatus called as a nuclear reactor.
A large amount of heat energy is generated due to nuclear fission. Rest parts of a nuclear power plant are very similar to conventional thermal power plants. It is found that fission of only 1 kg of uranium produces as. In order to turn nuclear fission into electrical energy nuclear power plant operators have to control the energy given off by the enriched uranium and allow it to heat water into steam.
That steam then drives turbines to generate electricity source.
