Nuclear power represents today an important source of energy, with its 436 nuclear reactors distributed worldwide, which produce around the 17% of the world total electricity production. An increasing share of nuclear energy is expected to cover the global requirements – increasing the present production up to a factor of 7 (or even more) worldwide up to the end of the century. This will present however a strong impact on fuel resources availability and price, as well as on nuclear waste production and permanent disposal issues. Scenario analysis provide a valuable tool in order to identify crucial issues of a development strategy, such as the fabrication and reprocessing capacity needs vs. time, the amount, composition and impact of the produced waste, the possible deployment path of a new technology according to the present facilities availability and technology. Scenario studies revealed very effective in the evaluation and comparison of the performance of the innovative systems (such as ADS, Fast Reactor burners and breeders, etc.), and thus they are performed today by many institutions all around the world. In the seminar a general introduction on scenario analysis and on its role in the resources evaluation and on the possible transmutation technologies performance evaluation will be presented. Then a general introduction to the COSI6 code, developed at CEA (Commissariat ŕ l’Energie Atomique et aux Energies Alternatives) - France, will be given. Finally some recent applications will be illustrated about the studies of the ADS EFIT and FR Critical Burners effectiveness for spent fuel waste legacy minimization in the European regional scenario.
Vincenzo Romanello graduated in 2003 in Nuclear Engineering (specialization: innovative nuclear plants) at the University of Pisa (Italy). Successively he worked at the development of a Monte Carlo model for the erosion-corrosion of ceramic materials in industrial furnaces. In 2008 achieved his PhD in Materials Engineering at the University of Salento (Italy). He is the main author of the CARL2.3 code, available at the NEA databank. Dr. Romanello worked on innovative LWR-HTR-GCFR symbiotic fuel cycles, publishing the results as technical papers at international conferences. From 2008 he works for KIT (Karlsruhe Institute of Technology), in Germany, in the IKET Institute (Institute for Nuclear and Energy Technologies), on innovative fuel cycle analysis and scenario studies. He is currently working in the field of scenario evaluation of the impact of innovative nuclear fast systems (ADS, FR, Hybrid) on uranium resources and waste minimization, both at regional and world level.
