What is Nuclear Energy used for

Nuclear Energy in all countries around the world is used mainly for energy, but because it is so hard to create and stabilize it is uncommon. For example France is run 80 percent by Nuclear Energy which is a good thing because it destroys the need for natural gas. Also unlike the other forms of energy, Nuclear energy gives of no co2 or any pollution into the atmosphere. Also through out the world there are many nuclear powered boats, the United States Navy has the most of them out of the world when it comes to aircraft carriers. But when it comes to vessels of war the Russians have all off them because the U.S stopped all the use of Nuclear Powered vessels.
