Research activities of INE address questions concerning long-term safety of high level radioactive waste disposal. Crucial fields of the German program for safe nuclear waste disposal, notably the geochemical aspects, are based on work performed at INE. Great expertise is available in actinide speciation by advanced analytical techniques, actinide geochemistry and migration.

INE is licensed and has the experimental and technical equipment for radionuclides of all types including reactor fuels. Laboratories are equipped to handle radioactive samples (HLW-glass, spent fuel, alpha emitters).

Actinide laboratories

Shielded hot cells (Spent fuel experiments)
Inert gas glove boxes (e.g. dedicated to migration experiments speciation)
Classical radioanalytical methods (a, b, g-spectroscopy, autoradiography)
ICP-emission spectrometry / Laser-ablation ICP-MS, ICP-mass spectrometry coupled to glove box, Ion chromatography, X-Ray fluorescence, X-Ray diffractometry)
Scanning electron microscopy, SEM

Actinide speciation techniques

Chemical speciation (e.g. Capillary electrophoresis-ICP-MS; Field flow fractionation-ICP-MS)
Speciation by laser spectroscopy: Time resolved laser fluorescence spectroscopy - TRLFS / Laser induced photoacoustic spectroscopy - LPAS / Laser induced breakdown detection - LIBD partly combined with controlled atmosphere glove boxes

Photoelectron spectroscopy, XPS, atomic force microscopy, AFM, AFM combined with glove box
Multifunctional X-Ray Absorption Fine Structure (XAFS) beam-line for actinides (see separate description)

Access requirements:

Security clearance and medical checks to ensure radiation protection requirements.
