Abstract
SKB has submitted RDandD Programme 2004 to SKI for review in accordance with the Act (1984:3) on Nuclear Activities. Based on SKI's review and the review statements received, SKI considers that: - SKB, and thereby the reactor owners, have fulfilled their obligations in accordance with paragraph 12 of the Act (1984:3) on Nuclear Activities, - Disposal in accordance with the KBS-3 concept seems to still be the most suitable way of disposing of spent nuclear fuel from the Swedish nuclear power programme. SKI would like to draw the Government's attention to the following evaluations and comments: - The question of who is responsible after the closure of a repository for spent nuclear fuel needs to be clarified. - SKB's plan of action is incomplete and its structure needs to be improved. The revised plan of action needs a more detailed account of the content of the basis for decision-making that SKB intends to present on different decision-making occasions. - As soon as possible, SKB should develop design premises for the canister and verify these premises in the next safety assessment which is planned for 2006. A clear and logical link between the detailed design premises for the canister and the

The revised plan of action needs a more detailed account of the content of the basis for decision-making that SKB intends to present on different decision-making occasions. - As soon as possible, SKB should develop design premises for the canister and verify these premises in the next safety assessment which is planned for 2006. A clear and logical link between the detailed design premises for the canister and the requirements on long-term safety of the repository is still lacking. - SKB should specify the limits for different parameters that are of importance for the canister function. The account must be based on an identification of defects that can occur and their consequences for canister integrity and repository function. - SKB should clarify how the work on KBS-3H (horizontal deposition of the canisters) is to be developed. An estimate of how much time and resources will be required is needed in order to prepare a body of material corresponding to that for KBS-3V (vertical deposition which is, so far, the most studied concept). - SKB should continue to participate in and contribute to the development of methodology for safeguards in connection with the disposal process. The area is the subject of considerable international interest and international developments should be taken into account, especially the process in Finland. - SKB should, already at this stage, initiate an analysis to evaluate technical protection systems for the monitoring of spent fuel canisters in connection with transportation. - The fuel area must also continue to be given a high priority in SKB's programme. The understanding of the fuel's reaction in contact with the groundwater has improved considerably in recent years. However, this understanding needs to be better demonstrated in the form of quantitative model studies of mechanisms and processes. - Prior to forthcoming licence applications, SKB needs to show, through practical experiments, that SKB's knowledge and modelling of the buffer function are adequate. - Prior to future licence applications, SKB needs to clarify and specify detailed requirements for the buffer and to ensure that there is material that can justify requirements and criteria for the buffer function. - Prior to forthcoming licence applications, SKB should present a concept for the backfill of tunnels that can be shown to have good prospects of meeting the requirements made on the repository function. Furthermore, SKB needs to prepare material that better justifies these requirements. - SKB needs to show how results from the Prototype Repository in the Aespoe Hard Rock Laboratory are to be used. - RDandD Programme 2004 lacks a clear link to the ongoing site investigations and research on issues of particular importance for assessing the suitability of the sites on different time scales. such as the occurrence of high rock stresses and saline groundwater. - The biosphere programme lacks clear links between site investigations and model development and a complete description of the models that are to be used in the safety assessment. - The development of models in the biosphere area must be prioritized and site data integrated into this work to verify the models in time prior to a licence application. Furthermore, the authorities assume that more long-term biosphere issues are being taken into account in SKB's new plan of action. - In its biosphere research, SKB should take into account the possibility of using radionuclide concentrations and flows as complementary safety indicators. - SKB should more clearly explain how it will ensure that studied climate scenarios will shed light on the most important climate-related stresses on the barrier function. - It is justifiable for the research conducted by SKB and Sweden in the area of PandT to maintain its current level so that international developments can be followed and to maintain and develop scientific and technical expertise in areas of importance for nuclear safety. - A clarification of the account of deep boreholes prior to the ultimate choice of a method and prior to licensing under the Environmental Code is needed. A comparison should be made with the KBS-3 method which utilizes safety assessment methodology including simple calculations. - SKB needs to intensify the work on decommissioning issues and in order to present detailed plans and considerations in RDandD Programme 2007. - SKB should investigate the shortest time required for the start of a licensing process for the disposal of decommissioning waste. - In the next RDandD programme, SKB should provide a more detailed description of the programme for long-lived low and intermediate-level waste. - SKB should take into account the viewpoint that long-term interim storage of waste while waiting for the construction of a repository should, as far as possible, be avoided and take this into consideration in its planning. - It is positive that SKB has incorporated social science research into its programme, since the findings from the research should be useful for the stakeholders to apply the research findings in ongoing and future consultation processes for an encapsulation plant and repository.}
