With the development of motor manufacturing technology, the expansion of the scope of electric energy application, and the rapid growth of the demand for electricity in production, power plants have emerged. There are many ways to generate electricity in power plants: thermal power plants that rely on thermal power, hydropower plants that rely on hydropower, and some power plants that rely on solar energy, wind power, and tidal power. Nuclear power plants that use nuclear fuel as energy have played an increasingly important role in many countries around the world.
