Nuclear reactor fuel contains ceramic pellets of uranium235 inside of metal rods. Before these fuel rods are used, they are only slightly radioactive and may be handled without special shielding. During the fission process, two things happen to the uranium in the fuel. First, uranium atoms split, creating energy that is used to produce ...

Yellowcake. The solid form of mixed uranium oxide, which is produced from uranium ore in the uranium recovery (milling) process. The material is a mixture of uranium oxides, which can vary in proportion and color from yellow to orange to dark green (blackish) depending on the temperature at which the material is dried (which affects the level of hydration and impurities), with higher drying ...

The uraniumbearing solutions are collected in a sump at the bottom of the mound and sent to the mill. Uranium is also produced by solution or in situ mining methods. This process involves circulating weakly alkaline or acid solutions through an ore body continued within a permeable sandstone aquifer.

The alternative, 'dry' process is used in the USA. In the dry process, uranium oxide concentrates are first calcined (heated strongly) to drive off some impurities, then agglomerated and crushed. At Converdyn's US conversion plant, U 3 O 8 is first made into impure UF 6 and this is then refined in a twostage distillation process.

A conventional uranium mill is a chemical plant that extracts uranium using the following process: Trucks deliver uranium ore to the mill, where it is crushed into smaller particles before being extracted (or leached). In most cases, sulfuric acid is the leaching agent, but alkaline solutions can also be used to leach the uranium from the ore.

The basis of the process is the formation of the stable 'uranyl tricarbonate1 complex ion, in which form the uranium passes into solution. To be able to dissolve in carbonate solution, the uranium must be present in the hexavalent (uranyl) state and it is. necessary, therefore, first to oxidise tetravalent (uranous) minerals.

The vast majority of nuclear power reactors use the isotope uranium235 as fuel; however, it only makes up % of the natural uranium mined and must therefore be increased through a process called enrichment. This increases the uranium235 concentration from % to between 3% and 5%, which is the level used in most reactors.
