Basic economics of power generation, transmission and

For renewables, fuel is generally free (perhaps with the exception of biomass power plants in some scenarios); and the fuel costs for nuclear power plants are actually very low. For these types of power plants, labor and maintenance costs dominate total operating costs. In general, central station generators face a tradeoff between capital and

Nuclear Power Plant

Turbine Trip. A nuclear power plant is a thermal power plant, in which a nuclear reactor is used to generate large amounts of heat. This heat is used to generate steam (directly or via steam generator) which drives a steam turbine connected to a generator which produces electricity. Steam turbine is a common feature of all thermal power plants.
