A nuclear reactor generates energy by using a chain reaction in which uranium, thorium and uranium-235 react to produce plutonium and then plutonium-238, creating a new nuclear energy source (NEN) that can be used to generate electricity. The basic principle is that the nuclear fuel (plutonium, uranium-235 and uranium-238) is placed in a water-cooled reaction vessel which is cooled via fission reactions. These reactions produce heat which drives a turbine – a machine that pulls or pushes air through a fluid with a specific speed according to the mass of the particles enclosed in the fluid. The machine can generate both electricity and heat (the same principle as that behind a lawnmower). This type of reactor does not produce toxic waste and as it produces both electricity and heat, has no emission limits and uses no fossil fuels. One key component to the process of converting nuclear energy into heat and power is the removal of heat, which takes some energy to do. Since some of the heat comes from radiation, there exists a risk of contamination and an overall higher energy consumption to do the same work. The Nuclear Power Plant Energy Cycle. The process for generating electricity is called the Nuclear Power Plant Energy Cycle. It is a complex chain, a process, whose elements are: – A fuel (nuclear fuel or fuel rods; the most commonly used is uranium-238); – Fission reactions (the most common are fission nuclei, the nucleus of which contains one or more neutrons, and the fusion of two nuclei), which create heat (this is an emission by the nuclear reaction); – Reactions associated with the cooling of the fuel rods and in which the heat is removed (this could be the use of water for cooling) and a reaction (which may be a reaction for the removal of some or all of the fission products or the addition of more fission products or some other process) where some of the heat produced is converted to electricity; The amount of heat is expressed in kWh. So, the amount of energy that is generated by a nuclear reactor is equal to the energy that is stored as heat in the reactor, in other words, the amount of power that is generated in a day. This total energy is referred to as the Electric Power Produced (EFP) by a nuclear power plant.
