Uranium

Uranium dioxide (UO 2) is the chemical form most often used for nuclear reactor fuel. Uranium-fluorine compounds are also common in uranium processing, with uranium hexafluoride (UF 6) being the form used in the gaseous diffusion enrichment process. Uranium tetrafluoride (UF 4) is frequently produced as an intermediate in the processing of uranium. Get price

Uranium: Its Uses and Hazards

Uranium-238 decays by alpha emission into thorium-234, which itself decays by beta emission to protactinium-234, which decays by beta emission to uranium-234, and so on. The various decay products, (sometimes referred to as "progeny" or "daughters") form a series starting at uranium-238. Get price

How is nuclear fission turned into electrical energy

Uranium pellets of the same length and diameter are arranged in rods, and these rods are gathered into bundles. The uranium bundles are placed in a container and submerged in water that acts as a coolant. The heat of the uranium bundles in the reactor core must be controlled to prevent overheating, which could cause the reactor to melt. Get price

Biofuels Basics

The heat breaks down biomass into pyrolysis vapor, gas, and char. Once the char is removed, the vapors are cooled and condensed into a liquid "bio-crude" oil. Gasification follows a slightly similar process; however, biomass is exposed to a higher temperature range (700C) with some oxygen present to produce synthesis gas (or syngas)—a Get price

Uranium Compound

Feedstocks for further uranium processing are dissolved in nitric acid to form a highly pure product that is converted to UO 2 (NO 3), 6H 2 O. The UO 2 (NO 3) 2 6H 2 O is converted to UO 3 by heating, reduced to UO 2 with hydrogen and finally converted to UF 4 with anhydrous HF. Get price

Data Processing

Data processing is the conversion of data into usable and desired form. This conversion or "processing" is carried out using a predefined sequence of operations either manually or automatically. Most of the processing is done by using computers and thus done automatically. The output or "processed" data can be obtained in various forms. Get price

Uranium processing

From alkaline solutions, uranium is most often precipitated by addition of sodium hydroxide, producing an insoluble sodium diuranate, Na 2 U 2 O 7. It can also be precipitated by acidification (to remove carbon dioxide) and then neutralization (to remove the uranium) or by reduction to less soluble tetravalent uranium. Get price
