[en] Some of the essential contributions during 1999 in order to fulfil the performance goals specified by the Government in the directive for SKI's regulatory and supervisory activities are summarized below. 1. Swedish nuclear facilities must have a satisfactory defence-in-depth system which prevents severe incidents and accidents due to deficiencies in technology, organization or competence as well as which prevents or limits the dispersion of radioactive substances to the environment in the event of an accident; 'The Swedish Nuclear Power Inspectorate's Regulations concerning Safety in Certain Nuclear Facilities' (SKIFS 1998:1) specify the overall safety requirements. The regulations 1999, mark a significant change in regulatory and supervisory strategy. In several areas, more stringent safety requirements are being developed. A proposal for new SKI regulations for operating personnel at nuclear power reactors has been prepared. A proposal for changes to the regulations (SKIFS 1994:1) for mechanical devices has also been prepared. SKI has investigated the safety requirements that it must establish for reactors during the first decade of the new century and SKI has started work on formalizing these requirements. Proposed regulations for the final disposal of spent nuclear fuel and nuclear waste have been prepared. SKI's review of the power companies safety analysis reports have, in several cases, resulted in requirements on technical plant improvements. 2. Nuclear facilities and substances under Swedish jurisdiction must be given adequate protection against terrorist attack, sabotage and theft; SKI's inspections and evaluations have not detected any deviations from this goal. 3. The Swedish Government must, in co-operation with the competent international control bodies, have adequate information on, and control over, the possession, use of and trading in nuclear material and nuclear technology under Swedish jurisdiction so that such nuclear material and nuclear technology are not used in breach of Swedish legislation and Sweden's international obligations within the area of safeguards; Safeguards inspections and evaluations have shown that Sweden has fulfilled its international obligations. This has also been confirmed by Euratom's safeguards directorate and the IAEA. 4. The final disposal of spent nuclear fuel and nuclear waste must be conducted so that any leakage of radioactive substances to the environment on different timescales can be expected to be below tolerable levels, so that future generations are not subjected to greater risks to health and environment than those tolerated by society at present; During the year, SKI continued to develop competence and methodology for the safety analyses that are necessary in order to judge whether planned facilities fulfil these basic requirements. In December 1999, SKI started its review of the Swedish Nuclear Fuel and Waste Management Co's (SKB) safety assessment for a geological deep repository for spent nuclear fuel based on the KBS-3 concept (SR97). Together with SSI, SKI has also organized an independent international peer review of SR97. 5: The nuclear industry must conduct a research and development programme which is comprehensive and fulfils the intended purpose so that the safe handling and final disposal of spent nuclear fuel and nuclear waste are achieved, so that methods exist for the decommissioning and dismantling of nuclear facilities, and so that the required funds are set aside for the resulting expenses; In spring 1999, SKI completed the review of SKB's research, development and demonstration programme which is submitted every three years. SKI found that the programme meets the requirements of the Act on Nuclear Activities. At the same time, SKI proposed that the Government establish certain conditions for the continued programme, with the aim of ensuring that the municipalities that consider participating in the continued site selection process obtain an adequate basis for their decisions. The Government has decided the fees and guarantees which will apply to cover future expenses, largely on the basis of the proposals made by SKI following its review of the industry's cost-estimates. 6. Decision-makers and the general public must be well informed of nuclear risks and safety as well as of the handling and final disposal of spent nuclear fuel and nuclear waste; SKI has aimed to be a reliable information provider that maintains considerable openness and provides a high level of service to the media, politicians and the general public. SKI has also been able to meet the need for information in the municipalities participating in feasibility studies prior to the selection of a site for a spent nuclear fuel repository. 7. SKI must actively contribute to the development and reinforcement of international nuclear safety and proliferation work, especially within the framework of the European Union; Together with other regulatory authorities within the EU, SKI has evaluated the reactor safety situation within the countries that have applied for EU membership. SKI has also participated in the European Commission's evaluation of forms of co-operation within the EU within reactor safety and has actively worked for more effective co-operation. In summary, it can be said that much has been achieved during 1999 to attain the performance goals for SKI's regulatory and supervisory activities. The regulatory and supervisory strategy has been further developed and regulatory and supervisory work and other tasks are continuously being developed through the SKIQ quality assurance system
