Fusion Energy - College Term Papers

Fusion Energy

A fusion reaction is one in which two atomic nuclei merge to form a
heavier nucleus. this is the process that happens in in the stars. In
average stars, like the sun, the process of fusion is converting hydrogen
nuclei (or protons) into helium nuclei. There is an enormous amount of
kinetic energy and gamma rays released in this process that heat the star's
interior, and this realease is what maintains it at the extreamly high
temperatures (greater than 10 million K) required to continue the fusion.

This process has been making the stars go for billions of years has
clear potential as a power source on earth. Once we have started the
reaction, Fusion requires no energy and ...

has been
some progress in discovering how we can use this. The two fusion reactions
that are the most promising both involve the heavier isotopes of hydrogen:

1) deuterium (composed of one proton and one neutron) Deuterium occurs
naturally as a minor constituent in all hydrogen-containing materials--such
as water--in quantities sufficient to meet all the energy needs of
societies for many billions of years.

2) tritium (composed of one proton and two neutrons). Tritium can be
bred from lithium by a neutron-induced reaction in a blanket that could
conceivably surround a fusion reactor. The western United States contains
large lithium deposits in the salts of dry lake beds, and much larger
quantities are dissolved in the sea.

Scientists are trying different combonations of these nuecli to make
fusion. The reaction that occurs with the greatest probability and at the
lowest temperatures involves the fusing of a deuterium nucleus with a
tritium nucleus to form a helium ...
