This thesis examines proton-induced radiation damage and sustainability of vanadium and copper-based target materials for High Current Accelerator-driven Neutron Source (HiCANS) applications, especially in the context of the High-Brilliance neutron Source (HBS) project at Forschungszentrum Jülich. Vanadium has been evaluated for 20 MeV proton irradiation target and copper is assessed for 3 MeV proton irradiation target or backing. [...]

Following the recovery of U and Pu from used nuclear fuel, Am becomes the primary contributorto the long-term radiotoxicity and heat load of the remaining high level waste.The AmSel (Americium Selective) process has been developed for the selective strippingof Am from PUREX (Plutonium Uranium Reduction Extraction) raffinate. It is basedon the combined use of two ligands with opposite selectivity and solubility, which workin a push-pull system, allowing a satisfactory separation of Am from Cm and all the lanthanides(Ln).
