UO2 is mixed with a dry bounder, zinc stearate, in several stages. At the first stage, 5-10 parts of the UO2 powder with a full amount of the zinn stearate required for the batch. At the second stage, the obtained mixture is mixed with 5-10 parts of the UO2 powder of the batch. At the third stage, the obtained mixture is mixed with the rest amount of the UO2 powder, and with U3O8, received after thermal oxidation of the UO2 defective tablets with an air. Aluminum oxide and graphite are mixed before the beginning of the reduction process.
Reduction is effected by high-frequency inductors through heating until a cake state.
Then the mixture is melted, playing the role of an anode. According to the newly-patented technology, centrifugal separation process at the first stage is carried out as a liquid flow upward. In accordance with the newly-patented technology, oil bubbles are kneaded under a dripping oil film. This method consists in deformation of the crystal by way of applying to it the mechanical load with its subsequent chemical pickling in a solution that selectively acts on defects.
