Presentation Transcript

  1. Transmutation and partitioning Thermal neutron spectrum Global (all M.A.) Heterogeneous ADS TRU Selective partitioning Homogeneous Critical Fast neutron spectrum Are nuclear systems too flexible ???

  2. Sustainability : Natural resources utilisation Minimising long-lived wastes Fissile material denaturation Reduced inventories in final disposal Reduced activity and radio-toxicity in final disposal Reduced inventories in the overall fuel cycle Reduced activity in the overall fuel cycle Economy Criteria

  3. Evaluation ? Geological Disposal

  4. Using PWR (TRU transmutation) : Medium term for TRU inventory reduction in reactor but strong impact on current fuel cycle facilities (some options are ruled out) Use of natural U resources Fissile material denaturation Using ADS : R&D needed for viability and feasibility Not sustainable per se Using FNR and global TRU recycling Sustainable 6 Gen IV systems : 4 fast neutron spectrum with global recycling of TRU Promising prospects for resolving new fuel cycle issues Some statements
