An overview on the recent advances in the field of high temperature studies of radionuclides in aqueous solutions will be given. Besides summarizing information on key technical aspects relevant for high temperature studies, the effect of increased temperatures on the complexation of trivalent actinides with chloride will be discussed in more detail, to illustrate newly derived in-depth understanding of the impact of increased temperatures on the (geo)chemical behaviour of trivalent actinides.

In the past 2 decades, X-ray absorption spectroscopy (XAS) and related synchrotron-based radionuclide speciation techniques have become indispensable, supporting issues in fundamental radiochemistry and nuclear waste disposal alike. The KIT Institute for Nuclear Waste Disposal operates two highly versatile beamline stations dedicated to investigating radionuclide materials by X-ray absorption fine structure (XAFS) spectroscopy techniques for samples with activities above the exemption limit.
