Radioactive waste inventory data are an essential element in the development of a national radioactive waste management programme since these data affect the design and selection of the ultimate disposal methods. Inventory data are generally presented as an amount of radioactive waste under...

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 differences exist both in the protection criteria being applied and in the methods for demonstrating...

These fact sheets present the radioactive waste management programmes of 20 OECD/NEA member countries. They include information about the sources, types and quantities of waste as well as how and by whom they are managed. References for further information are also provided for each country.

The concept of removing long-lived radioactive wastes from the human environment by disposal in deep geological repositories was developed several decades ago. In the intervening years, research efforts world-wide have increased our knowledge and understanding of how underground disposal systems...

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 disposal facility. It forms a central part of the safety case, and the results of the safety...

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-site waste with complex properties and to share experiences with the international community and NEA...

Regulators are major stakeholders in the decision-making process for radioactive waste management. The NEA Radioactive Waste Management Committee (RWMC) has recognised the value of exchanging and comparing information about national regulatory practices and having an informal, international...

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 disposal methods. Inventory data are generally presented as an amount of radioactive waste under...

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 intrinsic hazard of the waste decreases with time, but some hazard remains for extremely long periods....
