Une approche multi-experts, multi-acteurs et multicritères : exercice d’application à la gestion soutenable des déchets radioactifs de très faible activité (TFA)

Overview & Synopsis

The energy and territorial transition in which French and European environmental policy is embedded raises the issue of sustainable management of radioactive waste. In this context, IRSN has launched an innovative deliberative action-research approach based on the issue of the management of so-called "very low activity" waste (VLLW). A multi-actor, multi-expertise and multi-criteria approach has been set up for this purpose. This paper proposes an overview of the contributions and limitations of the multi-actor and multi-criteria approach for the sustainable management of VLLW waste. These aspects are discussed following a three phases approach. The core methodology focus on the management scenarios that are considered by experts and stakeholders based both on a "reasoned" voting protocol and a multi-criteria hierarchical process (multi-expertise and multi-stakeholder). This paper presents at an early stage a way to frame a methodology.
