At nuclear power plants the heat to make the steam is created when atoms split apart called fission.
Basic nuclear power station diagram. The basic principle of a nuclear power station is the same as a conventional thermal power station the only difference is that instead of using heat generated due to coal combustion here in a nuclear power plant the heat generated due to nuclear fission is used to produce steam from water in the boiler this steam is used to drive a steam turbine. In a nuclear power plant heat energy is generated by a nuclear reaction called as nuclear fission 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. Today we are going to read and learn definition working diagram layout advantages disadvantages and application of thermal power plant. Unlike a fossil fueled plant the nuclear plant s energy does not come from the combustion of fuel but from the fissioning splitting of fuel.
In a nuclear power plant uranium is the material used in the fission process. In a nuclear power station heavy elements such as uranium u 235 or thorium th 232 are subjected to nuclear fission in a special apparatus known as a reactor the heat energy thus released is utilised in raising steam at high temperature and pressure the steam runs the steam. Nuclear power engineering section international atomic energy agency wagramer strasse 5 p o. That steam then drives turbines to generate electricity source.
A nuclear power plant is a thermal power station in which the heat source is nuclear reactor. Reactor concepts manual nuclear power for electrical generation usnrc technical training center 1 7 0703 fission like a fossil fueled plant a nucl ear power plant boils water to produ ce electricity. 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. When the process is repeated over and over it is called a chain reaction.
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. Enriched uranium typically is formed into 1 inch long 2 5 centimeter long pellets each with approximately the same diameter as a dime. Structure of nuclear power plant design characteristics in the iaea power reactor information system pris iaea vienna 2007 iaea tecdoc 1544 isbn 92 0 102507 6. Box 100 a 1400 vienna austria nuclear power plant design characteristics.
Except for the reactor a nuclear power plant is similar to a large coal fired power plant with pumps valves steam generators turbines electric generators condensers and associated equipment.
