RED-IMPACT After a comprehensive inventory of existing and foreseen nuclear fuel cycle facilities in Europe, including a review of worldwide ongoing R&D programs on P&T, and assuming the potential evolution of P&T technologies and advanced fuel cycles (including Gen III & Gen IV reactors and ADS), the project has estimated the effect of P&T on waste management when using existing deep geological repository designs. • WP1 : Review of waste management and transmutation strategies, selection of fuel cycles scenarios • WP2 : Feasibility of the industrial deployment of selected scenarios and their impact on waste management • WP3 : Assessment of waste streams, waste features, leach resistance, heat generation, reprocessing capability etc. for selected fuel cycles. • WP4 : Assessment of the benefits of P&T/C in advanced fuel cycles for waste management and geological disposal. • WP5: Economic, environmental and societal assessment of fuel cycle strategies • WP6: Synthesis and dissemination of results Summary of RED-IMPACT results on the Impact of P&T… IEMPT10 / Mito (Japan) E.M.
