N2 - This report presents the results for the research programmes devoted to the study of the effect of a cement buffer on glass dissolution as foreseen in the Supercontainer. The Supercontainer Design with Ordinary Portland Cement has been selected as the reference design. In the framework of the Safety and Feasibility Case 1 (SFC-1) of the direct disposal of HLW glass in Boom Clay, the safety of the disposal system relies on the safety functions. For the HLW glass, this safety function is considered as latent in the first period after the repository closure (for ± 2500 years) and as a supplementary function thereafter. There is no specific requirement for the life time of the waste glass. Nevertheless, the stability of the HLW glass must be assessed and was therefore the principal objective of the research programmes 2004-2008 and 2009-2014. The programmes were meant to provide basic information on the glass stability in Supercontainer conditions. Together with literature data, this information is used to define reference glass dissolution rates for SFC1. The definition and argumentation of the reference dissolution rates is given in the level 4 technical SFC report on the vitrified waste release model.
