Nuclear energy originates from splitting uranium atoms through fission. At nuclear power plants, fission is used to generate heat and produce steam to power turbines and generate electricity. Construction costs for plants are very high but operating costs have decreased over time. Nuclear power produces radioactive waste that remains dangerous for hundreds of thousands of years, and accidents like Chernobyl show the risks of contamination. There are also concerns about nuclear materials being used for weapons.

8. BIBLIOGRAPHYINTRODUCTIONNuclear power is energy which is produced with the use of a controlled nuclear reaction. Many nations use nuclear power plants to generate electricity for both civilian and military use, and some nations also utilize nuclear power to run parts of their naval fleets, especially submarines. Some people favor an expansion of nuclear power plants because this form of energy is considered cleaner than fossil fuels such as coal, although nuclear power comes with a number of problems which must be addressed, including the safe disposal of radioactive waste products.The process of generation nuclear power starts with the mining and processing of uranium and other radioactive elements. These elements are used to feed the reactor of a nuclear power plant, generating a reaction known as fission which creates intense heat, turning water in the plant into steam. The steam powers steam turbines, which generate electricity and feed the electricity into the electrical grid.When nuclear power is used to power something like a submarine, the reactor runs the engines, with the steam directly powering the engines. In both cases, the reactor requires careful supervision, because runaway nuclear reactions must be stopped as quickly as possible to prevent serious problems. Many nuclear power plants have extensive automated systems which help to identify potential trouble spots, and these systems can also re-routepower , turn off parts of the plant, and perform other tasks which make the plant safer and cleaner.
