In atomic power plants – APP in short – the chain reaction of the uranium decay is allowed to run in a controlled way. The uranium rods in the reactor, which are bombarded with neutrons, are dipped in water, which slows down the neutrons and helps achieve a controlled nuclear fission. In addition, the fuel rods heat up the water to about 330°C. This heat is transferred in a heat exchanger to a second, non-radioactive water circulation, where the hot water evaporates and drives steam turbines. The energy is converted into electricity by means of the connected generators similar to other power plants.
