Nuclear Power

Producing energy from a nuclear power plant is very complicated.  The process of
nuclear energy involves the fission of atoms, the release of energy from fission
as heat, and the transfer of heat to electricity in power plants.

The process of splitting the atom is called nuclear fission.  Fission can take
place in many different kinds of atoms.  This explanation uses Uranium - 235,
the atom most commonly used in nuclear reactors.  The Uranium atom has many
protons, thus making it unstable.  Since the nucleus of the atom is so unstable
it wants to split itself apart, causing a spontaneous fission.  When the nuclei
of a Uranium atom splits apart, it splits into two atoms.  Commonly the nucleus
splits into Barium and Krypton; however, it can split into any two atoms as long
as the number of protons equals the original amount of the protons found in the
Uranium.  In addition, a mass amount of energy is released along with two or
three neutrons.  It is these neutrons that can begin a chain reaction, each
neutron that is given off could collide with another Uranium atom splitting it
apart.  Each of these fissioning atoms releases a very large amount of energy,
and some more neutrons.

This process continues causing a chain reaction withut any outside assistance,
and the Uranium has "gone critical"(Martindale, 794-195).  This chain reaction
is the basis for how nuclear power is made.

The amount of the energy that is given off in nuclear fission is astronomical.
To equal the amount of energy given off when splitting some uranium the size of
a golf ball, one would have to burn approximately twenty-five train cars full of
coal.  Presently, the planet contains twenty-five times more nuclear fuel
compared to fossil fuel.  On average, an atomic power plant can produce half a
million kilowatts of power.  As a comparison, a hair dryer takes about one
kilowatt (Jenny, 1-2).

The producing of energy from nuclear fission is very similar to using a very
common fossil fuel boiler.  The difference lies in the reactor, where the heat
is generated by fissioning material.  The most common of reactors is the
pressurized water reactor; however, there are many other types.

The pressurized water reactor is the most common reactor in the United States.
The reactor of a nuclear power plant is where the fissioning takes place.  The
Uranium is contained in fuel rods, each rod is sealed so no contamination occurs.
Many of these rods are then contained in...
