The construction of the Radioactive Ion Beam (RIB) Facility SPES-DT, within the framework of the new European RIB panorama is under study at the Laboratori Nazionali di Legnaro. The present project will be devoted to the production of neutron rich exotic nuclei, by using the fission process induced by a 40 MeV proton beam, 200 {mu}A current, on a multi-sliced Uranium Carbide (UCx) target. The UCx multiple thin disks target, developed at LNL is designed so that the power released by the proton beam is mainly dissipated by irradiation. Following the idea of the existing HRIBF facility at Oak Ridge National Laboratory (USA) where a proton primary beam of 40 MeV is also used, our target configuration is an evolution which permits to sustain a higher power on target. A high number of fission products (up to 10{sup 13} fission/s) will be obtained, still keeping a low power density deposition inside the target. The whole facility, together with the details on the Direct Target configuration, will be described. Thermo-mechanical calculations, pellets preparation and characterization, effusion-diffusion model predictions for the estimation of the release fraction of different radioactive nuclides will be discussed. A scaled (1:5) prototype of the Target system has been built and tested recently at HRIBF.
