A widely used method in the planning of protective actions is to establish a stakeholder network to generate a comprehensive set of generic protective actions. The aim is to increase competence and build links for communication and coordination. The approach of this work was to evaluate systematically protective action strategies in a case of nuclear accident. This was done in a way that all key players' concerns and issues related to protective actions could be aggregated into decisions a transparent and equal manner. We have developed and tested an approach called Facilitated Decision Analysis Workshop. The work builds on case studies in which it was assumed that a hypothetical accident had led to a release of considerable amounts of radionuclides and therefore various types of countermeasures should be considered. Six workshops were organised in the Nordic countries where the key players were represented, i.e., authorities, expert organisations, industry and producers.
