The purpose of our study is to estimate procedural fairness and distributive fairness of past decision-making process of the management policy for high‒level radioactive waste (HLW) and siting of repository in France. We conducted normative analysis by document review and interview survey with CLIS members and a sociologist participated in the public debate on HLW management policy in 2005 by CNDP. The results show that prior clarification when and how decision‒making of HLW management policy and siting of repository will be carried out in the step‒wise approach is important to enhance the legitimacy of the process. With regard to distributive fairness between generations, it is important to carefully consider responsibility of current generation and decision right of future generation in terms of equity and equality in the fair decision‒making process, because HLW management policy might depend on concept of distributive fairness between generations. It is necessary to carefully debate both interregional distributive fairness of negative legacy and economical distributive fairness in the fair decision‒making process, because they are inextricably linked together.本研究は文部科学省科学研究費基盤B(課題番号24402042,研究代表者 広瀬幸雄教授)の補助を受けて実施された
