Picture: Nuclear Vs Coal
The
picture above is meant to compare the emissions produced by Nuclear Power plant
and Coal Powered steam Turbine Power plant.Power
generation accounts for about one quarter of total emissions of CO2,
the main culprit in global warming. But generally, now people concerned about
climate change lacked information about the emissions of different types of power
plant.
With
coal, when it is burned, carbon dioxide, sulphur dioxide, nitrogen oxides, and
mercury compounds are released. For that reason, coal fired boilers are
required to have control devices to reduce the amount of emissions are released.
The average emission rates in the US from coal fired generation are: 2249
lbs/MWh of carbon dioxide, 13 lbs/MWh of sulphur dioxide and 6 lbs/MWh nitrogen
oxide. In addition to emission is the mining, cleaning and transporting of coal
to power plants.
Burning oil at
power plants produces nitrogen oxides, sulphur dioxide, carbon dioxide, methane,
and mercury compounds. The amount of sulphur dioxide and mercury compounds can
vary greatly depending on the sulphur and mercury content of the oil that is
burned. The average emissions rates in the United States from oil-fired
generation are: 1672 lbs/MWh of carbon dioxide, 12 lbs/MWh of sulfur dioxide,
and 4 lbs/MWh of nitrogen oxides. In addition, oil wells and oil
collection equipment are a source of emissions of methane, a potent greenhouse
gas. The large engines that are used in the oil drilling, production, and
transportation processes burn natural gas or diesel that also produce
emissions.Nuclear power plants do not emit
carbon dioxide, sulphur dioxide, or nitrogen oxides. However, fossil fuel
emissions are associated with the uranium mining and uranium enrichment process
as well as the transport of the uranium fuel to the nuclear plant.
