L’expérience internationale considérable accumulée au cours des 20 dernières années nous montre que les installations nucléaires peuvent être démantelées dans des conditions de sûreté, puis déclassée...

A “safety case” is the synthesis of evidence, analyses and arguments that quantify and substantiate a claim that a geological repository for radioactive waste will be safe after closure and beyond th...

Un « dossier de sûreté » est la synthèse des preuves, analyses et arguments qui permettent de quantifier et de justifier que le dépôt de déchets radioactifs en formation géologique restera sûr après ...

In November 2006, Hungary hosted the 6th National Workshop and Community Visit of the NEA Forum on Stakeholder Confidence (FSC). Participants included institutional authorities, local residents and s...

The OECD Nuclear Energy Agency (NEA) hosted an international symposium on “Safety Cases for the Deep Disposal of Radioactive Waste: Where Do We Stand?” in January 2007. The NEA has spearheaded import...

The presence of several barriers serving complementary safety functions enhances confidence that radioactive waste placed in deep geological repositories will be adequately isolated and contained to ...

Regulating the long-term safety of geological disposal of radioactive waste poses special challenges due to the very long timescales involved. This report has been prepared to help foster a common un...

L’une des principales activités de l’Agence de l’OCDE pour l’énergie nucléaire (AEN) dans le domaine de la gestion des déchets radioactifs est d’organiser des examens internationaux d’études et de pr...

This report examines the roles that storage plays, or might play, in radioactive waste management in OECD/NEA member countries. A better understanding of these roles provides valuable input to curren...

The Integration Group for the Safety Case (IGSC) of the Nuclear Energy Agency (NEA) is co-sponsoring a project with the European Commission to develop a greater understanding of how to achieve the ne...

The modelling of the key process of radionuclide sorption is of great importance in assessing the performance or safety of deep and near-surface repositories for radioactive waste. The first phase of...

A joint NEA-EC workshop entitled “Engineered Barrier Systems: Design Requirements and Constraints” was organised in Turku, Finland on 26-29 August 2003 and hosted by Posiva Oy. The main objectives of...

This report presents a consensus position in the form of a Collective Opinion of the Radioactive Waste Management Committee (RWMC) of the OECD Nuclear Energy Agency. It addresses the strategy for the...

Deep geological repositories of radioactive waste are designed and licensed based on a model of long-term safety which does not require the active presence of man. During the period of stepwise devel...

Regulating the long-term safety of geological disposal of radioactive waste is a key part of making progress on the radioactive waste management issue. A survey of member countries has shown that dif...

As part of its activities, the Regulators’ Forum of the NEA Radioactive Waste Management Committee has been examining the regulatory criteria for the long-term performance of geological disposal. In ...

The workshop was organized in Paris, on 1st-2nd September 1994, in co-operation with the OECD Environment Directorate. The focus was the concept of deep geological disposal and the associated non-tec...

Geological settings selected as potential host formations for the deep geological disposal of radioactive waste are chosen for, among other assets, their long-term stability and buffering capacity ag...
