Аннотация:The National Cooperative for the Disposal of Radioactive Waste (Nagra) in Switzerland was established on 4 December 1972.It is a cross-generational project to dispose of radioactive waste 'once and for all', including specialists from several scientific disciplines and communication experts.In September 2022, Nagra proposed a site for a deep geological repository for radioactive waste.Looking ahead to steps such as underground experiments or the specification of the layout for the deep geological repository, it is clear that many more important steps will have to be taken in the years following the siting decision.Nagra will adapt to new challenges in terms of competence and organization.Good cooperation with the siting region is just as essential as working at a high scientific level.In Switzerland, Nagra has just proposed the site for the deep geological repository for radioactive waste.What does this mean for the affected communities, also in terms of participation opportunities?
