OSTI ID:4824697
A process for recovering U from irradiated fuel elements also containing Al and Si is given in which solvent extraction of U is not materially affected by the presence of Si. The process is based on the solubility of Si in acid deficient aluminum nitrate solutions and comprises the steps of dissolving the fuel element in a limited quantity of HNO/sub 3/ such that the resulting solution is acid deficient and extracting uranyl nitrate with an organic solvent. The acid deficiency of the solution preferably is between 0.6 and 2 M. (D.L.C.)
