Short description of the work
The work carried out at the KIT-INE Laboratories included the flow through dynamic experiments for elution of U-contaminated sediments from the decantation waste of a U conversion facility (3 columns in total). The eluate was analysed for U, Th, pH and Eh and selected aliquots were analysed for alkalinity, cations and anions. In one of the columns U-233 was injected to investigate the retention of U. Strong retention of U was observed in all the experiments. Solid characterisation of the samples was conducted in parallel, comprising XPS and synchrotron measurements. The synchrotron measurements included bulk and micro analysis by XRF and XANES.
