What do you think when you hear the word Nuclear? Bombs, Mass Destruction, Radiation? Ever think nuclear energy? On September 29, 1901, Enrico Fermi built the first nuclear reactor called Chicago Pile-1. Now almost all the nuclear and is responsible for 19.5% of all of the United States electricity energy today is used in the production of power. Power generated by nuclear energy is the third largest power source in the United States and is a renewable energy source. Nuclear Reactors are a good source of energy because It is possible to generate a high amount of electrical energy in one single plant while emitting relatively low amounts of carbon dioxide. Even while emitting low amounts of carbon dioxide it still produces a more efficient
