Posted on November 15, 2018



Uranium Metal (U) & Depleted Uranium (DU)The highest member of the naturally occurring elements, uranium is of great importance as a nuclear fuel. Once thought to be quite rare in occurrence, it is now known to be more abundant than silver cadmium, or mercury. It is lustrous, silvery-white metal that is malleable, ductile, and softer than steel. Uranium is dense.uranium metal grinder,Preparation of uranium metal and dense UO2 shapes by the carbon .McClusky, James Keith, "Preparation of uranium metal and dense UO2 shapes by the carbon reduction of U3O8 " (1971).

Nuclear fuel - Wikipedia

Metal fuels have a long history of use, stretching from the Clementine reactor in 1946 to many test and research reactors. Metal fuels have the potential for the highest fissile atom density. Metal fuels are normally alloyed, but some metal fuels have been made with pure uranium metal. Uranium alloys that have been used.
