The OECD Nuclear Energy Agency (NEA) organised a workshop on the “Management of Uncertainty in Safety Cases and the Role of Risk” in Stockholm, Sweden, on 2-4 February 2004. The workshop’s main objec...

Le problème clé dans le démantèlement des installations nucléaires est l’élimination progressive des risques, au moyen d’une série d’actions de décontamination et de déconstruction qui doivent être r...

All national radioactive waste management authorities recognise today that a robust safety case is essential in developing disposal facilities for radioactive waste. To improve the robustness of the ...

For the past several decades, the Nuclear Energy Agency Salt Club has been supporting and overseeing the characterisation of rock salt as a potential host rock for deep geological repositories. This ...

This report is aimed at safety assessors of deep geological repositories and at technical specialists concerned with radioactive waste disposal. It is intended to improve communication among interest...

A workshop entitled the “Handling of timescales in assessing post-closure safety” of deep geological repositories for radioactive waste was organised in Paris on 16-18 April 2002 and hosted by the Fr...

The analysis of the long-term safety of radioactive waste disposal systems requires the use of mathematical models and scenarios that simulate repository behavior in response to future events. This r...

A key challenge in the development of safety cases for the deep geological disposal of radioactive waste is handling the long time frame over which the radioactive waste remains hazardous. The intrin...

Safety assessment is an interdisciplinary approach that focuses on the scientific understanding and performance assessment of safety functions as well as the hazards associated with a geological disp...

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 ...

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 ...

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...
