The Department of Physico-Chemistry at the CEA Saclay center has a large panel of analytical tools for applied research related to the development of sustainable nuclear energy. Experimental studies are carried out in several fields among which isotopic and element measurements of radioactive samples (including dissolved used fuels), and speciation of actinides in solution. Therefore the DPC is provided with analytical and chemical laboratories and especially a hot lab facility, composed of glove boxes and nuclearized instruments.

Part of the work at the DPC is focussed on:

  • the elementary, isotopic and radiochemical analysis, with high precision, on radioactive material
  • the study of speciation (characterization, coordination chemistry, measurement of basic thermodynamical and kinetic data…) of radionuclides and molecules in relevant media for nuclear fission energy.
  • the development and implementation of innovative techniques.

Within the TALISMAN network the DPC can propose the following techniques, all implemented in glove boxes:

Instruments for isotopic and elementary analysis of radioactive solutions:

  • Thermo-ionization mass spectrometry (VG II and Sector 54)
  • Multi-Collection ICP-MS (Isoprobe N) equipped with a reaction-collision cell
  • ICP-MS (Thermo Scientific X7) coupled with HPLC
  • Glove boxes for preparation and separation on gravimetric columns

Instruments for elementary analysis of solids:

  • Laser-induced breakdown spectroscopy (LIBS)

Instruments for speciation analysis of actinides in solution:

  • Time-Resolved Laser-Induced Fluorescence Spectroscopy (TRLFS) with tunable excitation and a temperature-controlled sample cell (0-80°C)
  • NanoElectrospray Mass Spectrometry (nanoESI-MS) with a triple quadripole for MS-MS
