Nuclear power plants produce about 10% of the world's electric power. Nuclear power is a controversial energy source: it requires little fuel and creates no air pollution, but the radioactivity released during accidents at nuclear plants has caused deaths and environmental damage. Nuclear energy is generated by splitting (or fissioning) atoms of uranium or even heavier elements. The fission process releases heat which is used to heat water and produce steam to drive a turbine that creates electricity. includes The operation of a nuclear reactor is part of an interconnected set of activities which mining, milling and transporting uranium; packing it in the most appropriated form; building and maintaining the reactor and associated generating equipment; treating and disposing of These fuel. and interactive industrial processes and many activities require extremely sophisticated specialised skills.
