Novel Approach

The paper proposes a multicriteria decision analysis (MCDA) framework for a comparative evaluation of nuclear waste management strategies taking into account different local perspectives (expert and stakeholder opinions). Of note, a novel approach is taken using a multiple-criteria formulation that is methodologically adapted to tackle various conflicting criteria and a large number of expert/stakeholder groups involved in the decision-making process. The purpose is to develop a framework and to show its application to qualitative comparison and ranking of options in a hypothetical case of three waste management alternatives: interim storage at and/or away from the reactor site for the next 100 years, interim decay storage followed in midterm by disposal in a national repository, and disposal in a multinational repository. Additionally, major aspects of a decision-making aid are identified and discussed in separate paper sections dedicated to application context, decision supporting process, in particular problem structuring, objective hierarchy, performance evaluation modeling, sensitivity/robustness analyses, and interpretation of results (practical impact). The aim of the paper is to demonstrate the application of the MCDA framework developed to a generic hypothetical case and indicate how MCDA could support a decision on nuclear waste management policies in a “small” newcomer country embarking on nuclear technology in the future.

Definition Of

A strong social and technical divide is particularly visible in the predominant understanding of technological innovation in modern societies. The field of Science and Technology Studies (STS) aims to overcome this divide, by focusing on the continuously entwined relationships between the social and the technical, that is, sociotechnical combinations. In this article, we argue that while it is reasonable to state that the social and the technical are entangled, it should be acknowledged that some issues are dealt with solutions that are more technical than others. A technical problematisation (the definition of an issue as a problem that is treated via a technical solution) is different to a social problematisation (the definition of an issue as a problem that is treated via a social solution) of the same issue. Our discussion is built upon examples from nuclear waste management, where the social–technical divide has been strong. However, more recently there has been a push for more democracy in technical decision making in this area, with much experimentation on public participation taking place. The only way these activities will successfully support such a democratising process is for them to be integrated into a renewed and explicitly acknowledged technical problematisation of proposed solutions.

Deliberative Processes

Despite increased legislative, political and social support for extended public engagement in environmental assessment, questions remain over the best means to integrate more analytic-deliberative processes within extended and fragmented decision-making frameworks. Using evidence from waste management decision-making in Britain this paper discusses institutional, cultural and technical barriers to effective integration of analysis and deliberation. The barriers are seen to limit effective participation intra decisions but particularly inter-decisions and hence to limit public impact on assessments and achievement of consensus on the optimum integrated waste management strategies. Institutional, technical and cultural barriers to effective process are discussed that compound the problems of enhancing public participation and promote maintenance of the status quo. Thus, environmental assessment still largely proceeds in advance of discussion with the public rather than through discussion with them.

Decision Making Processes

NUMO (Nuclear Waste Management Organization of Japan) has a responsibility for implementing geological disposal of vitrified HLW (High-Level radioactive Waste) in the Japanese nuclear waste management programme. Its staged siting procedure was initiated in 2002 by an open call for volunteer sites. Careful management strategy and methodology for the technical decision-making at every milestone are required to prepare for the volunteer site application and the site investigation stages after that. The formal Requirement Management System (RMS) is planned to support the computerized implementation of the specific management methodology, termed the NUMO Structured Approach (NSA). This planned RMS will help for comprehensive management of the decision-making processes in the geological disposal project, change management towards the anticipated project deviations, efficient project driving such as well-programmed R&D etc. and structured record-keeping regarding the past decisions, which leads to soundness of the project in terms of the long-term continuity. The system should have handling/management functions for the database including the decisions/requirements in the project in consideration, their associated information and the structures composed of them in every decision-making process. The information relating to the premises, boundary conditions and time plan of the project should also be prepared in the system. Effective user interface and efficient operation on the in-house network are necessary. As a living system for the long-term formal use, flexibility to updating is indispensable. In advance of the formal system development, two-year activity to develop the preliminary RMS was already started. The purpose of this preliminary system is to template the decision/requirement structure, prototype the decision making management and thus show the feasibility of the innovative RMS. The paper describes the current status of the development, focusing on the initial stage including work analysis/modeling and the system conceptualization.
