Public perception on safety is the key factor for achieving public acceptance of the high-level radioactive waste (HLW) disposal program. Past studies on public perception and HLW management have confirmed that the pubic do not share the confidence of the experts in safety and feasibility of HLW disposal. The importance of a more comprehensive approach to enhance acceptability of the HLW disposal technology is recognized.
This paper proposes a framework for inducing the implementers and regulators to improve compatibility of the HLW disposal technology with social values. In this framework, the implementers and regulators identify technical components which are subject to substantial influence from public concerns. Then, they manage these components through the following actions: (1) establishing policies, targets and plans to make these components compatible with social values, (2) developing and utilizing the components based on the above policies, targets and plans, (3) cheking the extent of compatibility through intensive risk communication and (4) improving the process of developing and utilizing the components. This framework requires information disclosure and evaluation by an independent body which are expected to intensify the incentive to take the above actions. Canada's environmental assessment review process regarding the HLW disposal concept suggests that this framework could work effectively.
