The diagram illustrates the general stages of how electricity are created by nuclear power station and sent to the public.
Overall, it is a man-made, linear process which includes 6 main stages, beginning with boiling water to steam and ending with sending electricity to public by power grid (and) also releasing the water after the steam cools down back to nature.
The complete procedure is irreversible and linear. The whole process could be considered as the steam generator be the first stage and the power grid as the final stage. Meanwhile, the water will flow through the cooling tower and back to nature. In addition, the complete process can be divided into four main factors. The first as the containment building, the second as the turbine plus generator, and the third as the transformer with the power grid. The last one would be the cooling tower, which help dealing the water source in the end.
Overall, the process all start with the Uranium fuel which is inside the containment building to boil the water. Then, the steam is the final product for the first stage, which is passed down to turbine through the steam pipes. Next, the steam is the power to start the turbine. In the coming stages, the generator and transformer create the electricity, and the power grid is the final step to send the electricity to public. Meanwhile, the steam used for the turbine will reduce to high temperature liquid form and being sent to cooling tower for the last step before releasing to nature.
