The analysis laboratory in the CEA Atalante facility at Marcoule (France) performs numerous R&D studies carried out in glove-boxes or in hot cells. The samples are measured in liquid phase, aqueous or organic. The concentration of the main actinides of interest (U, Np, Pu, Am and Cm) are determined by XRF in a hot cell using a device built specifically for these actinides analyses via their L-line X-ray between 13 and 15 keV. For sample with U and/or Pu in high concentrations, the hybrid K-edge densitometer is used. New software were developed for these devices.
