  1. Expert Group onImpact of Advanced Nuclear Fuel Cycle Options on Waste Management PoliciesA joint NDC-RWMC undertaking, with NSC supportprogress report by J.M. Cavedon, chairperson 8th Information & Exchange Meeting on Actinide and Fission Product Partitioning and Transmutation Las Vegas, 9-11 November 2004 NDC/RWMC EG Impact

  2. RWMC - Integrated Group for Safety Case statement • Conclusions of the IGSC Topical session”Potential Impacts of Partitioning and Transmutation on Long-term Waste Management and Disposal” 6 Nov 2002 • P&T will not eliminate the need for geological disposal of radioactive waste but has the potential to reduce volume, radiotoxicity and long-term heat production of the highest activity waste. • … • From the IGSC point of view, on the one hand no showstoppers for the new reactor concepts appeared even if there is not sufficient information on new waste types, on their characterisation, and especially on their long-term behaviour and in-situ performance. NDC/RWMC EG Impact

  3. RWMC- Integrated Group for Safety Case statement • Few, if any, full system studies have been performed to get the larger potential impacts picture including costs. From the IGSC point of view it is necessary to perform comprehensive systems studies and not to restrict the considerations to inventories and heat production of the highest activity waste. • If a society is to understand the implications of introducing this technology in the future, it must also be informed by studies of all aspects of the endeavour important to society, such as cost, land and resource commitment, and worker and public safety • Suggested interaction between RWMC and NDC is highly recommended, especially on the last two points NDC/RWMC EG Impact

  4. Mandate of the Expert Group „Impact“ • The study would aim at analysing a range of future fuel cycle options from the perspective of their impact on waste repository demand and specification. The study would focus on: • Assessment of the characteristics of radioactive wastes arising from advanced nuclear fuel cycle options. • Repository performance analysis studies using source terms for waste arising from such advanced nuclear fuel cycles. • Identification of new options for waste management and disposal. • Mandate approved both by NDC and IGSC NDC/RWMC EG Impact
