The operation of a nuclear power plant seems complicated only at first sight. After getting to know better the operational processes it becomes obvious that in many respects the setup of a nuclear power plant is very similar to that of traditional thermal power plants. In both cases the heat released in the boiler/reactor is transported by means of some coolant and the steam is used for generation. Reaching the turbine blades, the steam brings them into motion and the generator in its turn produces electric energy from the kinetic energy. From here the steam goes to the condenser for condensation, where it is converted into the liquid state. The cooled water after pre-heating goes back to the boiler or, in the case of a nuclear power plant with a pressurised water reactor, to the steam generator.
