Nuclear power plants and nuclear energy were born with the discovery of uranium. Uranium was discovered by the German scientist Martin Klaproth in 1789 (Uranium). The discovery of uranium led to future developments of new technologies such as nuclear power plants. Obninsk was a city built in 1946 by order of Josef Stalin to carry out research in the field of nuclear physics. German scientists captured during the Cold War helped Soviet scientists and others from around the world build the world's first nuclear power plant in 1954 (Miteva). Albert Einstein and Enrico Fermi both fled their respective countries to move to America. Einstein wrote a letter to President Roosevelt warning him of the dangers of atomic technology in Axis hands and pushing for atomic research. The project to build an atomic bomb was nicknamed the Manhattan Project. This project would employ 120,000 people and they would all have to keep it secret. It was so secret that Vice President Truman didn't learn about the Manhattan Project until he became president. In 1945, the first atomic bomb test was completed and the project was successful (Manhattan Project). The world would never be the same with the development of nuclear bombs and nuclear power plants. Nuclear power plants are changing the way the world works today. Today there are hundreds of nuclear power plants around the world producing energy. Nuclear power plants today are a controversial topic when it comes to providing electricity to the world. There are many who think that more nuclear power plants should be built and there are others who disagree and think that no more nuclear power plants should be built.
