NPP Model of a PWR type nuclear power plant. A nuclear plant is an industrial facility used for generating electricity from nuclear energy, which is characterized by the use of fissile materials that provide heat through nuclear reactions. This heat is used by a thermodynamic cycle to move a conventional alternator and produce electricity. These plants consist of one or more reactors, which are containers (usually called pots) inside which are housed rods or other geometric configurations of minerals with a fissile element (ie, that can fission) or fertile (which can become fissile by nuclear reactions), usually uranium and some plutonium fuels also generated from the activation of uranium. In the radioactive fission process, provides a reaction that is sustained and moderated by employing auxiliary elements dependent on the type of technology used.Cooling towers of nuclear power Cofrentes, Spain, ejecting water vapor. Nuclear power station in Rio de Janeiro, Brazil. Nuclear facilities are very complex structures for a variety of industrial technologies employed at the high security which gives them. The characteristics of the nuclear reaction are likely to be dangerous if you lose your control and proliferates Above a certain temperature at which melt the materials used in the reactor, and the occurrence of harmful radiation leaks by that or another cause. Nuclear power is characterized by producing, in addition to a large amount of electric power, nuclear waste that must hold in insulated tanks and monitored for a long time. In exchange, produces no air pollution from the combustion gases that produce the greenhouse effect, or require the use of fossil fuels for operation.However, indirect emissions resulting from its own construction, manufacturing of fuel and the subsequent management of radioactive waste (called management at all treatment processes of waste including storage) are not negligible. In Spain nuclear plants generate 21 of the electricity needed (REE).
