Glossaire :Nacelle [...] Nuclear reactor

Nacelle (see the French definition ): The nacelle is one of the parts of a wind turbine. It contains the equipment that produces electricity through rotor rotation.
Naphtha (see the French definition ): Naphtha is a product obtained from the fractional distillation of oil that is somewhere between gasoline and kerosene. It is classified as a light product because the hydrocarbons from which it is made have a lower molecular mass.
Natural radioactivity (see the French definition ): There are many radioactive elements commonly occurring in nature. The intensity of natural radioactivity is weak enough for life to develop.
Neutron (see the French definition ): Neutrons, along with protons, are the particles that make up the nucleus of an atom. They have no net electric charge.
Non-conventional oil (see the French definition ): The term “non-conventional” is applied for oil that cannot be extracted using conventional methods. There are two possible reasons for this. The first being that the oil is located in reservoirs which are difficult to access, for example in source rock, and the second being that the oil is too viscous or dense in nature. This includes extra-heavy oil, oil sands and oil shale.
Nuclear energy (see the French definition ): Nuclear energy is produced in nuclear power plants. The enormous amount of heat released during fission of uranium atom nuclei is combined with water to produce steam. This drives the turbines which then produce electricity. Nuclear energy accounts for nearly 80% of energy production in France.
Nuclear fission (see the French definition ): Nuclear fission is when a nucleus of an atom splits into two lighter nuclei (and into some elementary particles). This releases heat, which is a form of energy. This is the process currently used in nuclear power plants.
Nuclear fission energy (see the French definition ): Civil nuclear fission energy is used to produce electricity using uranium-235, a uranium isotope. This is an unstable and fissile atom, which means that its nucleus can split in half when bombarded by neutrons. This reaction gives off heat, radiation and one or more neutrons which in turn bombard other atoms. This is what is known as a chain reaction. The intense heat released is used to produce nuclear electricity.
Nuclear fusion (see the French definition ): Nuclear fusion is the process that produces the radiation energy of the sun and stars. The fusion of some light nuclei involves generating a heavier nucleus which gives off energy. The element that is usually involved in nuclear fusion is hydrogen, the lightest of all elements.
Nuclear fusion energy (see the French definition ): Nuclear fusion is energy that comes from the sun and stars. Two atomic nuclei join together to create a third heavier nucleus. This reaction releases a huge amount of energy. A temperature of 200 million degrees would be required to recreate this reaction on Earth! Via the ITER (International Thermonuclear Experimental Reactor) project, many countries are joining forces to prove that fusion could be an energy of the future. ITER will be located in France at the Cadarache research center for nuclear energy and testing will begin in 2018.
Nuclear power plant (see the French definition ): A nuclear power plant uses fission of atomic nuclei to produce heat, some of which is converted into electricity. A nuclear power plant works in a similar way to a gas-fired thermal power plant: the heat released by the fuel (uranium) heats the water turning it into steam. The steam drives a turbine coupled to an alternator, which produces electricity.
Nuclear reactor (see the French definition ): Located in the core of a nuclear power plant, a reactor is a type of huge boiler. It has 4 main components: a fuel (in which fission is produced); a heat-transfer fluid (that transports the heat produced); a moderator (which increases the success of the fission process, except in fast neutron reactors); and control rods (which control the fission chain reaction).
