Disposal of radioactive waste: can long-term safety be evaluated; Evacuation des dechets radioactifs: peut-on evaluer la surete a long terme

Technical Report:

Abstract

The long-term safety of any hazardous waste disposal system must be convincingly shown prior to its implementation. For radioactive wastes, safety assessments over timescales far beyond the normal horizon of social and technical planning have already been conducted in many countries. These assessments provide the principal means to investigate, quantify, and explain long-term safety of each selected disposal concept and site for the appropriate authorities and the public. Such assessments are based on four main elements: definition of the disposal system and its environment, identification of possible processes and events that may affect the integrity of the disposal system, quantification of the radiological impact by predictive modelling, and description of associated uncertainties. The NEA Radioactive Waste Management Committee and the IAEA International Radioactive Waste Management Advisory Committee have carefully examined the current scientific methods for safety assessments of radioactive waste disposal systems, as briefly summarized in this report. The Committees have also reviewed the experience now available from using safety assessment methods in many countries, for different disposal concepts and formations, and in the framework of both nationally and internationally conducted studies, as referenced in this report.

[Francais] Il convient d`etablir de facon convaincante la surete a long terme de tout systeme d`evacuation de dechets dangereux prealablement a sa mise en oeuvre. En ce qui concerne les dechets radioactifs, des analyses de surete portant sur des echelles de temps bien superieures a celles normalement retenues pour la planification sociale et technique ont deja ete effectuees dans de nombreux pays. Ces analyses offrent le principal moyen d`etudier, de quantifier et d`expliquer aux autorites competentes et au public la surete a long terme de chacun des concepts et sites d`evacuation choisis. Ces analyses reposent sur quatre principaux elements: la definition du systeme d`evacuation et de son environnement, la determination des processus et evenements susceptibles d`influer sur l`integrite du systeme d`evacuation, la quantification des incidences radiologiques grace a la modelisation previsionnelle et la description des incertitudes connexes. Le Comite de la gestion des dechets radioactifs de l`AEN et le Comite consultatif international de l`AIEA sur la gestion des dechets radioactifs ont etudie attentivement les methodes scientifiques actuelles permettant d`analyser la surete des systemes d`evacuation des dechets radioactifs, telles qu`elles sont brievement resumees dans le present rapport. Ces Comites ont egalement examine l`experience actuellement disponible par suite de l`application de methodes d`analyse de surete dans de nombreux pays, dans le cas de differents concepts d`evacuation et formations receptrices, et dans le cadre des etudes menees a l`echelon tant national qu`international, dont il est fait mention dans ce rapport.}
