Abstract
Solids at the interface of mixer-settlers may disturb the extraction of U and Pu in the first extraction cycle of the Purex process. For the study of solids in nuclear fuel solutions 14 g of LWR fuel with a burnup of 45 000 MWd/tU have been dissolved in 7M HNO//3. The fuel has been irradiated for 4 years and cooled down for 2. 4 years. The solids in the solution were removed by 4 consecutive filtration steps with nucelpore filters after 2. 5, 20, 68 and 164 hours. The filter residues are characterized by x-ray microanalysis in a scanning electron microscope.
