Two steps of a pyrochemical route for the recovery of actinides from spent metallic nuclear fuel are being investigated at JRC-Karlsruhe. The first step consists in electrorefining the fuel in molten salt medium implying aluminium cathodes. The secon

The solubility behavior of hexavalent neptunium (Np) was systematically investigated as function of [CaCl2] = 0.25–4.5 mol dm−3 [0.252–5.26 mol (kg H2O)−1] and pHm 8–12 (pHm = − log{m(H+)/mol (kg H2O)−1}) under oxidizing conditions adju

It has been proven, by the analysis of macroscopic amount of materiel pressed into pellets, that Raman spectrometry is a well suited technique to determine precisely the chemical compositions of uranium ore concentrates (UOCs), which is useful inform
