The Kristallin-I performance assessment indicates that the Swiss concept for disposal of vitrified HLW deep in the crystalline basement of Northern Switzerland will offer sufficient safety. This conclusion is based on a scenario analysis and an associated consequence analysis using an extensive model chain. The planned system of engineered barriers is shown to be particularly robust and ensures that most of the radionuclide inventory decays to insignificance in the near-field--both in the base case and in most altered evolution scenarios. The geosphere barrier can also be very effective, but conclusive demonstration of this places strong requirements on characterization of the geosphere. The radiological impact on hypothetical individuals inhabiting the groundwater discharge area is estimated by calculating doses via a variety of exposure pathways, following dilution, transport and accumulation in the biosphere. Detailed evaluation of perturbations of the base case scenario and of altered evolution scenarios is currently ongoing.
