TEPCO's Fukushima Daiichi nuclear power plant accident prompted extensive decontamination work. The decontaminated soil and incinerated ash generated by the process are scheduled for final disposal by March 2045 outside Fukushima Prefecture. The final disposal is unprecedented worldwide. Clarifying their acceptability will contribute to the final disposal of decontaminated soil and incinerated ash, as well as add knowledge about the perceived risk of low-concentration radioactive waste. A questionnaire survey was conducted to assess the psychological factors influencing final disposal acceptability. The results of the structural equation modeling demonstrated stable results, with risk perception decreasing acceptability, social benefits increasing acceptability, and personal benefits having limited impact. The initiative for the final disposal of decontaminated soil and incinerated ash can facilitate the reconstruction of Fukushima Prefecture after the disaster. Trust and intergenerational expectations are critical factors influencing the acceptability of this disposal. The responses were classified based on the relevance of moral norms using cluster analysis and moral foundations. The influence of each element on acceptability varied depending on the cluster. Trust was identified as the most influential factor in acceptability, regardless of the level of importance placed on moral norms.
东电福岛第一核电站事故引发了大规模去污作业。由此产生的去污土壤和焚烧灰计划于 2045 年 3 月在福岛县外进行最终处置。这在全球范围内尚属首次。明确其可接受性将有助于去污土壤和焚烧灰的最终处置，并增加对低浓度放射性废物感知风险的认识。进行了问卷调查以评估影响最终处置可接受性的心理因素。结构方程模型的结果表明结果稳定，风险感知降低可接受性，社会效益提高可接受性，个人利益影响有限。去污土壤和焚烧灰的最终处置倡议可以促进福岛灾区的重建。信任和代际期望是影响这种处置可接受性的关键因素。使用聚类分析和道德基础对基于道德规范相关性的响应进行了分类。根据聚类，每个元素对可接受性的影响不同。无论对道德规范的重视程度如何，信任都被确定为可接受性的最具影响力因素。
