1. Euradwaste04 – Partitioning and transmutation - Panel discussion Transmutation and partitioning Fast neutron spectrum Critical Heterogeneous Homogeneous Thermal neutron spectrum ADS Global (all M.A.) TRU Selective partitioning Are nuclear systems too flexible ???

2. Euradwaste04 – Partitioning and transmutation - Panel discussion Criteria 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

3. Euradwaste04 – Partitioning and transmutation - Panel discussion Evaluation Evaluation ? Geological Disposal

4. Euradwaste04 – Partitioning and transmutation - Panel discussion Some statements 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
