Objetivo The main objectives of the proposed project are to develop processes for the separation of minor actimides : 1. without the generation of secondary solid wastes. 2. minimising the majority of the drawbacks encountered in the previous processes mentioned above, such as the precipitation of radionuclides; difficulties in the stripping of the actimides from the solvent, etc... Consequently, we propose to following principles for the design of the processes: 1. develop molecules (extractants, diluents, aqueous reagents) that can be at the end of their use in the processes, converted into gases which can be released into the atmosphere (CHON principle). 2. no reduction of the acidity of the HLLW to be processed. Accordingly, the proposed separation strategy includes two routes and broad sets of measurable objectives : 1. the first route corresponds to a single cycle process for which we must establish the fundamental criteria using molecular design, synthesis and evaluation for the simultaneous selective extraction of An (III) from Ln (III) in HNO3 aqueous solutions (< 2M). 2. the second route includes several extraction cycles, the first to extract the actimides and lanthanides from the HLLW, and the second cycle to separate the An from the Ln. Some effort will be devoted to the Am/Cm separation accordi to the time available. The proposal objectives clearly comply with those of the programme, particularl A.2 Fuel Cycle Concepts and A.2.
