“Spent fuel Dissolution in Supercontainer conditions” Reporting period 2009-2012. Level 5 Report “Spent fuel Dissolution in Supercontainer conditions” RP.W&D.0060: Programme 2009-2014. Final report.

This report corresponds to the level 5 topical report, requested as a deliverable in WP4 and WP5 of the research plan RP.W&D.0060 (O/N reference LTBC03-SF-01), “Spent fuel dissolution in Supercontainer conditions: research programme 2009-2014”, as part of the framework agreement with O/N reference CCHO-2009-00940000 (SCK•CEN reference CO-90-08-2214-00). It presents the results of leach experiments with depleted and Pu doped UO2 in cement waters, to determine the dissolution rate and mechanisms of these matrixes, as part of the scientific basis for the selection of reference dissolution rates of real spent fuel for performance calculations in the framework of the Safety and Feasibility Case 1 (SFC-1) [ER-150] concerning the geological disposal of radioactive waste according to the Supercontainer design.
