KIT-INE, Karlsruhe Institute of Technology - Institute for Nuclear Waste Disposal, Karlsruhe, Germany

The Institute for Nuclear Waste Disposal (Institut fuer Nukleare Entsorgung, INE) belongs to the newly founded Karlsruhe Institute of Technology (KIT), a fusion between the Karlsruhe Research Center of the German Helmholtz Association and the University of Karlsruhe. INE research activities focus on the geochemical aspects of the long-term safety of nuclear waste disposal. Sound expertise and state-of-the-art, advanced analytical techniques are available for actinide speciation and geochemistry, investigation of actinide migration, as well as research into partitioning and the vitrification of high level liquid waste.

KIT-INE has a number of facilities available as pooled facility within the scope of the ACTINET-I3 Project. The active laboratories at KIT-INE are licensed and equipped for working with radionuclides of all types including reactor fuels and alpha emitters. The INE-laboratories with their state-of-the-art equipment and instrumentation are located in one building complex. The INE-Beamline for actinide research is also available as a ACTINET-I3 pooled facility for X-ray spectroscopy investigations and is located on the same KIT site, not far from the INE laboratories.

The following facilities and techniques are offered:

Actinide laboratories

  • Hot cells (Spent fuel experiments)
  • Glove boxes, partly with inert gas atmosphere (e.g., dedicated to migration experiments, speciation)
  • Classical radioanalytical methods (a, ß, γ-spectroscopy, autoradiography)
  • ICP-OES, ICP-MS, high resolution ICP-MS coupled to glove box, Laser-ablation, Ion chromatography, X-ray fluorescence, X-ray diffractometry
  • Scanning electron microscopy, SEM
  • NMR spectroscopy of actinide containing solutions, 400 MHz, variable temperature, 2-channel setup for multinuclear experiments
  • 400 MHz NMR spectroscopy of liquid samples

Actinide speciation techniques

  • Chemical speciation (e.g., Capillary electrophoresis-ICP-MS; Field flow fractionation-ICP-MS)
  • Photoelectron spectroscopy, XPS, atomic force microscopy, AFM
  • Laser spectroscopy
    - Time resolved laser fluorescence spectroscopy - TRLFS,
    - Laser induced breakdown detection - LIBD
    partly combined with inert gas glove boxes
  • Multifunctional X-ray spectroscopy (XAFS) beam-line for actinides (more...)
    - Experiments with activities up to 106 times the limit of exemption
    - Various detection schemes and sample environments
    - XAFS, GI-XAFS, PFY-XAFS, RIXS, micro(µ)-focused studies possible
