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.

This study examined the determinants of public acceptance of siting a repository for High-level radioactive waste (HLW), focusing on procedural fairness and trust. To examine the presumption, the study implemented a hypothetical scenario experiment that manipulated two factors: an opportunity of voice as an antecedent of procedural fairness and similarity value to the authority as a component of trust. Results indicated that affective reaction, procedural fairness, and trust determined public acceptance. A process analysis indicated that the effect of procedural fairness was strengthened when the trust on similarity was negative.

One reason of not being decided a candidate site for geological disposal of high level radioactive waste is that strong opposition occurs once a name of the place where residents live even if they can understand the necessity of the facility. Therefore, we hypothesized that people would accept the decision if they consent the decision way beforehand under the condition everyone can be involved in as a potential interest party (the ignorance of veil). A hypothetical scenario survey was conducted in Japan. The results revealed that the decision way and the decision under the ignorance of veil were likely to be accepted more than the current decision way even if they became candidate site. Moreover, the decision way under the ignorance of veil was evaluated higher procedural fairness, while the current way was low procedural fairness.

Japan Atomic Energy Agency (JAEA) has promoted the Mizunami Underground Research Laboratory (Mizunami URL) as one of generic URL to perform basic research of waste disposal technology for about twenty years. JAEA had carried out consultation activities with local people and community from 1995 when the plan of Mizunami URL opened at the time, because an early approach of JAEA caused a sense of social distrust and concern, which the study area of Mizunami URL would be candidate site of real repository. In this paper, we conducted normative analysis intended for the consultation activities from a viewpoint of procedural justice and distributed justice, used as the social psychological framework in terms of public NIMBY facility. The results show that it is important to develop local partnership, composed of representative local people and organization at early start and to support deliberation by local partnership in the aspect of information and financial administration.

This study examined determinants of public acceptance regarding siting a geological disposal facility for high-level radioactive waste (HLW) in France, where a candidate site has been selected following on a variety of public involvement activities. Data from 886 French residents were collected in 2014 by an internet survey that was performed near a district that is a candidate for a HLW repository and in an outlying region away from the candidate site. Results indicate that procedural fairness, intergenerational subjective norm, public benefit and personal benefit were significant factors for public acceptance in dealing with the NIMBY issue in addition to factors such as trust, risk perception and stigma, dealt with in previous research on risk analysis. Furthermore, personal benefit and affect had stronger impact on the acceptance than public benefit, procedural fairness and intergenerational subjective norm.

This study demonstrates the significance of "the veil of ignorance" to promote public acceptance of siting a facility for geological disposal of high-level radioactive waste, which fosters procedural fairness. We conduct a hypothetical scenario experiment in Japan and manipulate the decision way setting two conditions; one is present Japanese way that decides by application from municipalities or offer of the Government, the other is a Switzerland way that all regions have possible to be a candidate site starting from blank. The results indicated that respondents in Switzerland way condition accepted more and regarded the process fairer than those in present Japanese way condition. The potential of adopting the idea of "the veil of ignorance" is discussed.
