The disposal of radioactive waste is a striking example with which to trace the changing relationship between technology, society and policy when dealing with societally relevant controversial issues. The change is characterized by a transition from a technocratic approach to an approach with more intense cooperation and public participation. We analyze the societal discourse of a failed disposal project for low- and intermediate-level waste at the Mount Wellenberg site, Canton of Nidwalden (Central Switzerland). Insights are based on a case study in 2006, with focus groups, expert interviews, a media analysis, a representative canton-wide postal survey and targeted in-depth stakeholder interviews. The article focuses on the relationship of safety and process aspects. The data suggest that both are prime issues and people recognize the need for disposal of radioactive waste in a technical system but only if a fair procedure is guaranteed. We conclude that a sound balance between safety and procedural aspects needs to be found and thus a functional-dynamic view of public involvement is necessary, i.e. distinct levels of involvement (ranging from mere information up to empowerment) must fit the corresponding technical and non-technical requirements of a stepwise decision-making process.

The accident at the Fukushima nuclear power plant in spring 2011 spurred Germany and Switzerland to phase out nuclear technology. To ensure future electricity supply, this phase-out requires a strong commitment to accept alternative production technologies and energy strategies. This study examined if and how laypeople's preference for electricity produced by nuclear power and the alternatives in Switzerland has been affected by the Japanese disaster. An online study was conducted in February (N = 69) and repeated in June 2011 (N = 57), applying the same questionnaire to both samples. The study included a preference rating task involving nuclear, gas, photovoltaics, wind power, and hydropower, and choice-based conjoint tasks. The conjoint tasks contained attributes such as production technologies and price instruments. Participants had to choose their preferred combination of attributes. The results show that laypeople's preference for nuclear power dropped significantly between February and June 2011, whereas their preferences for other technologies changed only marginally. Furthermore, the envisaged mid-term “stepping stones” of gas and electricity imports on the way to renewable energy have been highly unpopular and have remained so after the Fukushima accident. Transitioning from nuclear energy to renewable energy, therefore, will likely be challenging. [ABSTRACT FROM AUTHOR]

In major infrastructure projects, experts are usually regarded as responsible for producing and evaluating facts, whereas the public plays a role as far as values are concerned. In this study, we investigate the potential of values and value-related concepts in explaining acceptance of a deep ground repository for high-level radioactive waste in Switzerland. The study was in two parts, first, screening for relevant values using a questionnaire (N = 500) and, second, face-to-face interviews with 42 participants from the first part. Although the questionnaire could not predict overall acceptance on the basis of value concepts, interesting relative differences were nevertheless revealed between participants who were or were not affected by the potential siting of a deep geological repository in their own community. Additionally, the interviews offered insights into how values are related to the participatory process designed by the Swiss authorities. [ABSTRACT FROM PUBLISHER]
