Entrée Usine Areva Malvesi
An entrée (, ; ) in modern French table service and that of much of the English-speaking world (apart from the United States and parts of Canada) is a dish served before the main course of a meal. Outside North America, it is generally synonymous with the terms ''hors d'oeuvre'', appetizer, or starter. It may be the first dish served, or it may follow a soup or other small dish or dishes. In the United States and parts of Canada, the term ''entrée'' refers to the main dish or the only dish of a meal. Early use of the term The word ''entrée'' as a culinary term first appears in print around 1536, in the ''Petit traicté auquel verrez la maniere de faire cuisine'', in a collection of menus at the end of the book. There, the first stage of each meal is called the ''entree de table'' (entrance to the table); the second stage consists of '' potaiges'' (foods boiled or simmered "in pots"); the third consists of one or more ''services de rost'' (meat or fowl "roasted" in dry hea ...

Narbonne
Narbonne (, also , ; oc, Narbona ; la, Narbo ; Late Latin:) is a commune in Southern France in the Occitanie region. It lies from Paris in the Aude department, of which it is a sub-prefecture. It is located about from the shores of the Mediterranean Sea and was historically a prosperous port. From the 14th century it declined following a change in the course of the river Aude. It is marginally the largest commune in Aude. But the capital of the Aude department is the smaller commune of Carcassonne. Geography Narbonne is linked to the nearby Canal du Midi and the river Aude by the Canal de la Robine, which runs through the centre of town. It is very close to the A9 motorway, which connects Montpellier and Nîmes to Perpignan and, across the border, to Barcelona in Spain. There is also a recently renovated train station which serves the TGV to Spain, Paris and Calais, which in turn connects to the Eurostar. Narbonne is only 10 km from Narbonne Plage (beach), but it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Uranium Tetrafluoride
Uranium tetrafluoride is the inorganic compound with the formula UF4. It is a green solid with an insignificant vapor pressure and low solubility in water. Uranium in its tetravalent ( uranous) state is important in various technological processes. In the uranium refining industry it is known as green salt. Production UF4 is prepared from UO2 in a fluidized bed by reaction with HF. The UO2 is derived from mining operations. Around 60,000 tonnes per year are prepared in this way annually. A common impurity is UO2F2. UF4 is susceptible to hydrolysis as well. UF4 is formed by the reaction of UF6 with hydrogen gas in a vertical tube-type reactor. UF4 is less stable than the uranium oxides and reacts slowly with moisture at ambient temperature, forming UO2 and HF, the latter of which is very corrosive and toxic; it is thus less favourable for long-term disposal. The bulk density of UF4 varies from about 2.0 g/cm3 to about 4.5 g/cm3 depending on the production process and the pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radioactive Waste
Radioactive waste is a type of hazardous waste that contains radioactive material. Radioactive waste is a result of many activities, including nuclear medicine, nuclear research, nuclear power generation, rare-earth mining, and nuclear weapons reprocessing. The storage and disposal of radioactive waste is regulated by government agencies in order to protect human health and the environment. Radioactive waste is broadly classified into low-level waste (LLW), such as paper, rags, tools, clothing, which contain small amounts of mostly short-lived radioactivity, intermediate-level waste (ILW), which contains higher amounts of radioactivity and requires some shielding, and high-level waste (HLW), which is highly radioactive and hot due to decay heat, so requires cooling and shielding. In nuclear reprocessing plants about 96% of spent nuclear fuel is recycled back into uranium-based and mixed-oxide (MOX) fuels. The residual 4% is minor actinides and fission products the latter of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thermal Organic Reduction
A thermal column (or thermal) is a rising mass of buoyant air, a convective current in the atmosphere, that transfers heat energy vertically. Thermals are created by the uneven heating of Earth's surface from solar radiation, and are an example of convection, specifically atmospheric convection. Thermals on Earth The Sun warms the ground, which in turn warms the air directly above. The warm air near the surface expands, becoming less dense than the surrounding air. The lighter air rises and cools due to its expansion in the lower pressure at higher altitudes. It stops rising when it has cooled to the same temperature, thus density, as the surrounding air. Associated with a thermal is a downward flow surrounding the thermal column. The downward-moving exterior is caused by colder air being displaced at the top of the thermal. The size and strength of thermals are influenced by the properties of the lower atmosphere (the ''troposphere''). When the air is cold, bubbles of wa ...

Uranium
Uranium is a chemical element with the symbol U and atomic number 92. It is a silvery-grey metal in the actinide series of the periodic table. A uranium atom has 92 protons and 92 electrons, of which 6 are valence electrons. Uranium is weakly radioactive because all isotopes of uranium are unstable; the half-lives of its naturally occurring isotopes range between 159,200 years and 4.5 billion years. The most common isotopes in natural uranium are uranium-238 (which has 146 neutrons and accounts for over 99% of uranium on Earth) and uranium-235 (which has 143 neutrons). Uranium has the highest atomic weight of the primordially occurring elements. Its density is about 70% higher than that of lead, and slightly lower than that of gold or tungsten. It occurs naturally in low concentrations of a few parts per million in soil, rock and water, and is commercially extracted from uranium-bearing minerals such as uraninite. In nature, uranium is found as uranium-238 (99. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
