Abstract
Procedure for the production of uranium metal, from an aqueous solution of uranyl nitrate containing at least 0.5 gram-molecule of free nitric acid per gram-molecule of uranium, characterized by the succession of the following phases: uranyl nitrate to uranous nitrate with hydrogen gas at room temperature, in the presence of a catalyst formed by a metal of the finely divided platinum group or distributed on an inert support; precipitation of the double fluoride of uranium and an alkali metal by adding at least 5.5 gram-molecules of aqueous hydrofluoric acid and 1.2 gram-molecules of an alkali metal salt per gram molecule of uranium; drying of double fluoride to a water content less than or equal to 1%; mixture of fluoride with magnesium powder in excess of the stoichiometric amount; formation by pressing at specific pressure greater than 0.5 ton per cm2 of a cylindrical tablet; reduction of the pellet, placed inside an induction coil in a container of non-conductive material that has not been hermetically sealed and filled with vibrating refractory powder, while during preheating in the course of the reaction and for a few minutes after In this case, the coil is supplied with a specific power of at least 2 Kw per Kg of uranium to be reduced and with a frequency such that a penetration of the induced currents is sufficient to ensure homogeneous heating of the tablet.
