This study examined effects of a management policy and of site selection process for high-level radioactive waste disposal on acceptance of siting repository in a German case. Data from 1,000 German residents, assigned by population composition ratio of 16 states, were collected in 2018 by internet survey. We assumed three steps of acceptance: management policy, site selection process, and siting repository. We also hypothesized national consensus of the former two steps were relevant factors on the acceptances. Results indicated that national consensus of site selection process directly had an effect on acceptance of siting repository, while acceptance and national consensus of management policy had an effect on national consensus of site selection process. In addition, acceptances of management policy and site selection process had effects on procedural and interpersonal fairness, while national consensus of management policy and site selection process as well as acceptance of site selection had effects on distributive fairness.

The purpose of this research is to investigate the effects of compensation framing on acceptance of a high level radioactive waste (HLW) geological repository. The results demonstrated that there were no main effects of condition, which suggested that the framing of compensation had no significant impact on acceptance of a HLW geological repository.

This study examined the impacts of the Fukushima Nuclear Power Plant accident on the public acceptance of siting a disposal facility of high level radioactive waste (HLW). 1930 Japanese people completed longitudinal internet surveys that were measured before the Fukushima Nuclear Power Plant accident (in February, 2011) and after the accident (in February, 2012). Results indicated that the level of public acceptance of investigation for siting of geological disposal facility was decreased after the accident. Intergenerational subjective norm, social benefit and procedural fairness determined public acceptance consistently before and after the accident. Moreover, the perceptions of stigma and intergenerational subjective norm were altered dramatically after the accident. Our results show that the Fukushima nuclear accident reminds people of ethical problems of acceptance of geological disposal facility of HLW.
