Abstract
Regarding the geological disposal of high-level radioactive waste (HLW) in Japan, there has been no widespread public debate. As no candidate site selection has progressed and it is long way to proceed the HLW disposal project. In order to overcome this situation, currently, technical one-way communication by experts is conducted under assumption of citizen’s lack of technical safety. The approach has been criticized as a ”Deficit model”, but because of its ambiguity, it is still discussed today. This paper applies the method of P2M theory to aim the public debate of the HLW disposal by analyzing the citizen’s policy preference change with 4 social acceptance factors (technical, institutional, economic and regional factors). The “Deficit model” communication case is tested and shows the limit of the current dialogue project of the HLW geological disposal which is placing too much on the technical safety.
