Nuclear Energy : The Good, The Bad, And the Debatable

By: Dr. Lana Aref

Excerpt: How is Nuclear Energy Produced? Nuclear energy is produced when an atom's nucleus is split into smaller nuclei by the process called fission. The fission of large atoms, such as Uranium 235 and Plutonium 239, produces a great deal of energy. In fact, the fission of 1 gram of Uranium 235 produces the same amount of energy as the combustion, or burning, of 3 tons of coal (1)! The energy produced by the fission of uranium or plutonium can be harnessed to produce el...
