[en] Allan Hedin (SKB, Sweden) presented the current situation of the SKB programme. SR 97 was developed a few years ago and feedback of the international peer review was presented in a previous IGSC topical session. The primary function of the KBS-3 disposal concept is isolation, and the second function retention. Regarding the site investigation, two sites will be studied from 2002 to 2008. An application for the encapsulation plant will be submitted in 2006, supported, as regards long term safety of the deep repository in which the canisters are to be emplaced, by a safety assessment 'SR Can'. The SR Can report is planned by end 2005 and an interim report on methodology by summer 2004. The report will contain references to applicable regulations issued by SKI and SSI regarding long-term safety of deep repositories. The principal compliance criterion states that the annual risk for individuals should be less than 10-6. When developing the report, an audit of the NEA FEPs database will be used as a check list. One or more initial states of the system will be selected as the basis for the analysis, corresponding to a 'reference state' and 'deviating' states. Preliminary analyses are made in order to gain insight into the system evolution and to inform the subsequent choice of scenarios; a number of alternative scenarios will be identified. If evolution for a certain scenario implies canister ruptures, then a calculation of consequences will be performed. With respect to the handling of uncertainty, Allan Hedin noted that various approaches exist that may prove suitable for providing rigorous uncertainty analyses. During the discussion, it was acknowledged that one key step is to get feedback from the regulator on the selection of methodology for handling uncertainty before going forward. Regarding the initial state of the system, it was noted that the point in time for the initial state will depend on the component you are looking at. During the discussion the relevance was noted of having one report per aim, viz SR Can, to support the application for the encapsulation plant, and SR Site, to support a siting decision in 2008. The coupling between the biosphere and the other components was also noted as an issue in the discussion
