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 health and the environment. The barriers include the natural geological barrier and the engineered...

This book, prepared by NEA member country experts, contains data and analyses relevant to nuclear power plant life management and the plants' extended, longer-term operation (LTO). It addresses technical, economic and environmental aspects and provides insights into the benefits and challenges...

This book presents the proceedings of a workshop entitled the "Handling of Timescales in Assessing Post-Closure Safety" of deep geological repositories for radioactive waste organised in Paris on 16-18 April 2002 and hosted by the French Institute for Radiological Protection and Nuclear Safety...

Since the accident at Chernobyl in 1986, many countries have intensified their efforts in nuclear emergency planning, preparedness and management. Experience from the NEA nuclear emergency exercises (INEX 1 and INEX 2) indicated a need to improve the international system of communication and...

High power proton accelerators are being studied for their potential use in the transmutation of nuclear waste. The Second Workshop on Utilisation and Reliability of High Power Proton Accelerators, organised by the NEA Nuclear Science Committee, placed special emphasis on accelerator-driven...

Interest in nuclear energy continues to grow in many countries as a means to ensure security of energy supply and to limit greenhouse gas emissions from the power sector. In this context, recyclable materials constitute an asset for broadening the resource base for nuclear fuel supply,...

When preparing the safety case for a deep geological repository of radioactive waste, the integration of wide-ranging information from multidisciplinary sources is a complex task. This has provided the motivation for establishing AMIGO, an OECD/NEA international project on “Approaches and...

Structural materials research is a field of growing relevance in the nuclear sector, especially for the different innovative reactor systems being developed within the Generation IV International Forum (GIF), for critical and subcritical transmutation systems, and of interest to the Global...

In this workshop proceedings, Spanish stakeholders and delegates from 14 countries discuss current co-ordination of radioactive waste management decision making in Spain. Findings were shared from Cowam-Spain, a co-operative research project on the involvement of local stakeholders, the...

During irradiation, nuclear fuel changes volume, primarily through swelling. This swelling is caused by the fission products and in particular by the volatile ones such as krypton and xenon, called fission gas. Fission gas behaviour needs to be reliably predicted in order to make better use of...
