The Geothermal Rising (formerly the Geothermal Resources Council) is a professional educational association for the international geothermal community. [21] Therefore, comparison with other power generation methods is strongly dependent on assumptions about construction timescales and capital financing for nuclear stations. A JRC study measures the effects of high prices on poverty indicators from an innovative [52][53] Newer stations are designed for a 40 to 60-year operating life. [5], Nuclear power plants have a carbon footprint comparable to that of renewable energy such as solar farms and wind farms,[6][7] and much lower than fossil fuels such as natural gas and brown coal. WebThe energy efficiency of a conventional thermal power station is defined as saleable energy produced as a percent of the heating value of the fuel consumed. [46] The reprocessed uranium, which constitutes the bulk of the spent fuel material, can in principle also be re-used as fuel, but that is only economic when uranium prices are high or disposal is expensive. Coal is an impure fuel and produces more greenhouse gas and pollution than an equivalent amount of petroleum or natural gas. Only the most significant fuel source is listed for power stations that run on multiple sources. The main condenser is a large cross-flow shell and tube heat exchanger that takes wet vapor, a mixture of liquid water and steam at saturation conditions, from the turbine-generator exhaust and condenses it back into sub-cooled liquid water so it can be pumped back to the reactor by the condensate and feedwater pumps. It is commonly used as the speed control mode of the governor of a prime mover driving a synchronous generator connected to an electrical grid.It works by controlling the rate of power The condenser is a heat exchanger which is connected to a secondary side such as a river or a cooling tower.
