Moreover, after separation, if the transmutation is not available, the actinides can be conditioned into stable dedicated solid matrices (Partitioning and Conditioning strategy). Yttrium-stabilized zirconia and thoria are discussed in the international nuclear community as candidates for the fixation of long-lived actinides as target material for transmutation and as stable materials for long-term final disposal. The aims of the following work are twofold: determine the impact of the addition of actinides, simulated by cerium on the properties of the matrices and study the possibility of synthesising homogeneous ceramics using simple fabrication routes. Within this framework, (ZrY)O_2_-_x-CeO_2 and ThO_2-CeO_2 powders with variable ceria contents (from 0 to 100 %) were synthesised by a co-precipitation method of nitrate solution. The influence of ceria concentration on the powder' properties, such as thermal behaviour and the evolution of material crystallisation during annealing, was investigated in detail by thermogravimetry (TG) coupled with differential scanning calorimetry (DSC) and X-ray diffraction (XRD). Both systems crystallise at high temperature in a stable solid solution, fcc, fluorite type structure and follow the Vegard's law for the complete range of ceria. For both systems a critical concentration of 20 mol% has been established. For ceria concentrations lower than 20%, the properties of the system are mainly controlled by the matrix. Pellets with different ceria concentrations were compacted from these powders by using different technological cycles. In order to obtain materials with reliable properties, the technological parameters of each chosen fabrication route, have been optimised. By employing mild wet methods (calcination at 600 C, wet-grinding in acetone and fractionation in acetone), (Zr,Y,Ce)O_2_-_x pellets with densities of up to 0.97 TD can be obtained. In the case of the (Th,Ce)O_2 system, pressing by repressing from non-milled powder was selected as the fabrication route, allowing the fabrication of pellets with densities of up to 0.98 TD. In both cases, materials with homogeneous repartition of pores, well formed grains and boundaries and good mechanical properties were obtained. (orig.) INIS Training Seminar 14-16 Novemner 20114

The GAMMASPHERE array was used for all the experiments in conjunction with a 4 chargedparticle detector arrays (MICROBALL, LUWUSIA) and neutron detectors (NEUTRON SHELL) to allow for the detection of rays in coincidence with the evaporated particles. An extended 60Ni level scheme is presented, comprising more than 270-ray transitions and 110 excited states. Their spins and parities have been assigned via directional correlations of rays emitted from oriented states. Spherical shell-model calculations in the fp-shell characterize some of the low-spin states, while the experimental results of the rotational bands are analyzed with configuration-dependent cranked Nilsson-Strutinsky calculations.
