Radioactive waste repositories are designed to isolate waste from the living environment without human intervention over extended periods of time. Nevertheless, the intention is not to abandon the re...

放射性廃棄物は、医療・産業・研究・発電など幅広い活動から発生する。このような廃棄物はすべて、人の健康と環境の保護を最優先して安全に管理しなくてはならない。何十年にも及ぶ研究活動を経て、国際科学界は今では、高レベル放射性廃棄物を深地層最終処分場（DGR）に定置することが安全かつ効果的であると確信するに至っている。
各国政府は、それぞれが最良であると信じるエネルギー・環境政策を実施する絶対的な権利と責...

National radioactive waste management programmes are in various phases of siting facilities and rely on distinct technical approaches for different categories of waste. In all cases, it is necessary ...

National programmes for radioactive waste management require very large amounts of data and information across multiple and disparate disciplines. These programmes tend to run over a period of many d...

The NEA Clay Club has been gathering the key geoscientific characteristics of the various argillaceous formations that are – or have been – studied in NEA member countries in the context of radioacti...

The OECD/NEA Working Group on the Characterisation, the Understanding and the Performance of Argillaceous Rocks as Repository Host Formations, namely the “Clay Club”, examines the various argillaceou...

The diversity in classification schemes across countries has restricted the possibility of comparing waste inventories and led to difficulties in interpreting waste management practices, both nationa...

Many different estimates for the cost of radioactive waste disposal in geological repositories have been published. This study, aimed at the general reader, illustrates why the published cost estimat...

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...

The Preservation of Records, Knowledge and Memory (RK&M) Across Generations initiative was launched by the Nuclear Energy Agency in 2011 to foster international reflection and progress towards this g...

Radioactive waste inventory data are an important element in the development of a national radioactive waste management programme since these data affect the design and selection of the ultimate disp...

The NEA Expert Group on Fukushima Waste Management and Decommissioning R&D (EGFWMD) was established in 2014 to offer advice to the authorities in Japan on the management of large quantities of on-sit...

The feasibility and costs of spent nuclear fuel management and the consequent disposal of ultimate waste continue to be the subject of public debate in many countries, with particular concern often e...

Radioaktivt avfall av alla slag måste hanteras på ett ansvarsfullt sätt nu och i framtiden med hänsyn både till människors hälsa och till skyddet av miljön. Avfallet måste också skyddas mot intrång. ...

Most experts worldwide agree that radioactive waste disposal in engineered facilities, or repositories, located in appropriate formations deep underground, provide a suitable waste management option ...

In the deep disposal of radioactive waste, the presence of several barriers serving complementary safety functions enhances confidence that the waste will be isolated and contained to protect human h...

Ce rapport présente une synthèse des enseignements tirés par le Forum de l’AEN sur la confiance des parties prenantes (FSC) concernant la gouvernance de la gestion à long terme des déchets radioactif...

A major activity of the OECD Nuclear Energy Agency (NEA) in the field of radioactive waste management is the organisation of international peer reviews of national studies and projects. The peer revi...

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...
