Power Plant
How a Nuclear Power Plant Works
the fan blades of turbines, which turn generators that produce electricity. In
a fossil fuel plant either coal, natural gas or oil is burned to produce heat.
In a nuclear plant, uranium is the fuel.
The uranium is formed into cylindrical pellets that are smaller than a
thimble, but each one has the energy of nearly a ton of coal. The pellets
are stacked in fuel rods arranged into assemblies, which form a reactor’s
core.
A reactor starts when control rods in the assemblies are withdrawn and
fission begins. The fuel rods heat water circulating through sealed,
stainless steel piping pressurized to 2,300 pounds per square inch to
keep water liquid at 600º F. This sealed system passes through huge
vessels, called steam generators, heating a separate water supply into
steam. After it turns the turbine blades, the steam is fed into a condenser
and cooled by water from STP’s reservoir. The condensed water is then
pumped back to the steam generators and the cycle starts again.
