How are nuclear power plants like other power plants?
Nuclear power plants works almost like a thermal power plant.
Instead of-boiler which gives heat here a atomic reactor gives heat..
In both cases steam is produced and steam drives the turbines.Turbines are coupled to Generator which convert heat energy to mechanical energy and generator converts mechanical energy to electric energy.
Fuel rods are kept in the reactor at critical mass with control rods and shut of rods in position..When the control rods are lifted the fission reaction starts and supply heat and the heat exchanges produce steam.
