kept a person's heart beating. Then we started to build more reactors and produce more of the substance but mostly for our nuclear weapons programs. Along with reactors, sometimes comes a meltdown which can produce harmful effects if it isn't controlled quickly enough. After such instances as the Hanford, Washington reactor meltdown and the accident in the U.S.S.R. at the Chernobyl site, no one wanted to hear about the use of plutonium. The United States government banned nuclear testing and also ended the production of plutonium.(Ref. 5) Now we are in a dilemma. We are in need of future sources of energy to power our nation. We are running out of coal and oil to run our power plants.(Ref. 7) We also need it to further our space exploration program. People need to understand the advantages to using plutonium and that the disadvantages are not as catastrophic as they seem. With the turn of the century on its way, the reemergence of plutonium production will need to be a reality for us to continue our way of life. In 1941, a scientist at the University of California, Berkeley, discovered something that would change our planet forever. The man's name, Glenn T. Seaborg, and what did he discover?, the element plutonium.(ref. 10) Plutonium, or Pu #94 on the periodic table, is one of the most unstable elements on the earth. It is formed when Uranium 235, another highly unstable element, absorbs a neutron. Plutonium is a silvery-white metal that has a very high density of 19.816 g/cm3.(ref. 10 ) It has been rarely found in the earth's crust but the majority of the substance has to be produced in the cores of nuclear reactors. Plutonium can be found fifteen different forms, or isotopes and their mass number can range from 232-246.(ref. 13) Radionuclide batteries used in pacemakers use Pu-238, while Pu-239 is used in reactors and for Nuclear weapons.(ref. 13) This paper will focus on the isotopes Pu-238 and Pu-239. Plutonium can be very advantageous for the United States. It can be used for several purposes. The three major advantages to using this element are for an energy source, power for nuclear propulsion in space exploration and thermo-electric generators in cardiac pacemakers. The first use for plutonium, nuclear power, is obviously the most beneficial use. Plutonium 239 can be used to power nuclear reactors. The average nuclear reactor contains about 325 kilograms of plutonium within its uranium fuel.(ref. 7) This complements the uranium fission process. With the continually decreasing supply of coal and oil to power our nation, we need a substitute to complement our energy needs and right now the best replacement is that of nuclear energy.(ref. 7) At the moment there are one hundred and ten nuclear power plants in the United States and they produce one- fifth of the nations electricity. Nuclear energy has been proven to be the cheapest, safest, cleanest and probably the most efficient source of energy.(ref. 7) Nuclear power plants do not use as much fuel as the plants burning coal and oil. One ton of uranium produces more energy than several million tons of coal and plutonium can produce much more energy than uranium.(ref. 12) Also the burning of coal and oil pollute our air and the last thing
