La libération des sites d’installations nucléaires des contrôles radiologiques est généralement l’une des dernières étapes du déclassement. À ce jour, seul un petit nombre de projets en ont fait l’ob...

Any long-term radioactive waste management project is likely to last decades to centuries. It requires a physical site and will impact in a variety of ways on the surrounding community over that whol...

Tout projet de gestion de déchets radioactifs à long terme durera vraisemblablement des décennies, voire des siècles. Il nécessitera un site et influera de bien de manières sur la communauté environn...

L’environnement sociopolitique de la gestion des déchets radioactifs a connu de profonds changements ces dernières années. La concertation avec les parties prenantes est devenue l’un des principes di...

Un nombre significatif d’installations nucléaires devra être démantelé dans les prochaines décennies. Dans ce contexte, les pays membres de l’AEN accordent de plus en plus d’importance à l’implicatio...

Le Comité de la gestion des déchets radioactifs (RWMC) de l’AEN a mis en avant les fondements environnementaux et éthiques relatifs au stockage géologique et s’est prononcé sur sa faisabilité techniq...

À toutes les phases du cycle du combustible nucléaire, mais aussi lorsque l’on utilise des substances radioactives dans l’industrie, la recherche et en médecine, on produit des déchets radioactifs. L...

Le présent document donne une vue d’ensemble synthétique des avancées de la réglementation et des recommandations, aux niveaux tant international que national, et des initiatives internationales et m...

Alors que les programmes nationaux de stockage géologique progressent vers leur mise en œuvre, le concept d’« optimisation » et les exigences réglementaires associées suscitent une attention accrue. ...

À l’heure actuelle, on observe une variabilité considérable dans le format, le contenu et les pratiques d’estimation des coûts, que ce soit à l’intérieur d’un même pays ou lorsque l’on franchit les f...

La thématique de ce 7e atelier du Forum sur la confiance des parties prenantes (FSC) concernait la mise en œuvre du programme français de gestion des déchets de haute activité et de moyenne activité ...

L’expérience des projets de démantèlement de centrales nucléaires laisse entendre que l’on pourrait simplifier ces opérations si l’on y accordait davantage d’attention au moment de la conception ou p...

En ansenlig internationell erfarenhet som inhämtats under de senaste 20 åren visar att kärntekniska anläggningar kan rivas och avvecklas på ett säkert sätt när ett beslut väl fattats att avsluta drif...

Any significant decisions regarding geologic disposal of radioactive waste will need a comprehensive public review and a thorough involvement of all relevant stakeholders, such as waste generators, w...

Integrated performance assessments (IPAs) of radioactive waste repositories deep underground are made at different stages of repository development in order, for example, to allow full-scale developm...

GEOTRAP is the OECD/NEA Project on Radionuclide Migration in Geologic, Heterogeneous Media carried out in the context of site evaluation and safety assessment of deep repository systems for long-live...

In underground repositories for radioactive waste, significant quantities of gases may be generated as a result of several processes. The potential impact of gas generation, accumulation and migratio...

Reversibility of decisions is an important consideration in the stepwise decision-making process that is foreseen for engineered geologic disposal of radioactive waste. The implications of favouring ...

La réversibilité des décisions est un concept important dans le processus de décision par étapes qui est prévu pour le stockage géologique des déchets radioactifs. Les implications liées à la récupér...

This report, intended for a broad readership, provides a concise overview of the decommissioning and dismantling of nuclear facilities and associated issues in NEA member countries. It draws upon a d...

Cet ouvrage, à l’intention d’un large public, présente une synthèse de la situation du déclassement et du démantèlement des installations nucléaires ainsi que des questions connexes dans les pays mem...
