Short description of the work
The associated pooled facility (APF) CEA – ATALANTE was visited by the Ph.D. student Sebastian Bahl from 28/09/15 – 03/10/15. All proposed work could be carried out successfully. Before this time period, 4 Pu glass samples were cut from glass rods, embedded in a resin and optically polished for the planed experiments. One day was required to record Raman spectra of all four Pu doped borosilicate glasses in the box line of the ATALANTE facility. The evaluation of the data will be performed in Karlsruhe. The Pu glasses were then cleaned and transferred to a preparation glovebox. The sample holder cells, designed and constructed at KIT-INE, were on-site modified according to the preparation process requirements. The Pu glass specimens were mounted by Mr. Delrieu in the cells and all surfaces were checked for contamination. As one surface revealed a small increase in activity, the cell was replaced by a backup sample holder on which no contamination was detected after the preparation. The procedure required also one day. The last day, the U doped alumosilicate glasses were mounted in a similar sample holder. No contamination was determined. In addition organizational paperwork was done to prepare the visit of the Ph.D. student Pierrick Chevreux at INE for X-ray absorption measurements (XAS).
All sample holder containing glass specimens were finally prepared for transport and arrived safely and in time in Karlsruhe at INE. Samples were analyzed by high energy resolution X-ray absorption near edge structure (HR-XANES) spectroscopy in November 2015 at INE-Beamline by the help of young scientist Mr. Chevreux. The evaluation of the data will be done in collaboration of Ph.D. students Chevreux and Bahl.
