Nuclear waste becomes a political issue - Sweden 1972 Government Committee on Radioactive Waste 1976 Stipulation Act advised permission to start new reactors granted only if reactor owner: 1.has agreement for reprocessing of spent fuel and has demonstrated how and where absolutely safte final storage of the high-level waste obtained from reprocessing can be effected or 2. has demonstrated how and where absolutely safe final storage of spent, unprocessed nuclear fuel can be effected 1985 Central interim storage facility, Clab 1988 Final repository for low and LILW, SFR
Roles and legislation The Government The Swedish Radiation Authority The Swedish National Council for Nuclear Waste Environment Court Municipality The Planning and Building Act The Swedish Environment Code The Nuclear Activities Act The Radiation Protection Act The Financing Act

Nuclear waste becomes a political issue - Finland Accident at Three Mile Island lead to increased conserns Options: Reprocessing and foreign solutions (SF sent back to Soviet Union) High reprocessing prices/low uranium prices led to 2nd thoughts 1983 the Goverment defined a programme for direct disposal of SF in Finland 1994 Export and import of any nuclear waste was prohibited
Research and Development start in Stripa

Challenges different organisational cultures different time tables lead to different priorities at different times different regulations and differences in licensing procedures
Challenges comprehensive cooperation means effective ties between programmes problems/issues in one country easily move over to the other as well decisions in one country affect decisions in the other the regulators in the two countries have found each other as well moving from RD&D to industrialization will change the context of cooperation new options for cooperation will to open
Conclusion programme for geologic disposal of spent fuel is possible without excessive costs, but TVO s/posiva s programme owes a lot of its success to international contacts and cooperation information and experience provided by SKB has been of special importance access to international information and cooperation made it possible to focus the work on site and site-specific topics no language barrier to Swedish RTD information presently strong political consensus on solving the nuclear waste problems in the waste producer s own country in contrast to recommendations for foreign solutions in the early 1980 s sets constraints to international cooperation
General comments international contacts and cooperation make sense only in the context of a sufficiently extensive own programme information transfer and application otherwise difficult to realise with increasing stakes the fairness of cooperation also becomes important the ties created by close cooperation need to be acknowledged and accepted differences in the national contexts and conditions need to be acknowledged and may become increasingly difficult as the number of partners increases
