Large quantities of materials arising from the decommissioning of nuclear facilities are non-radioactive per se. An additional significant share of materials is of very low-level or low-level radioac...

Nuclear sites around the world are being decommissioned and remedial actions are being undertaken to enable sites, or parts of sites, to be reused. Although such activities are relatively straightfor...

This NEA Policy Brief provides a concise outline of the current outlook for final disposal of radioactive waste in NEA member countries. It describes the challenges, context, stakeholders and potenti...

Radioactive waste repositories are designed to be intrinsically safe in that they are not dependent on the presence or intervention of humans. In response to this challenge, the Nuclear Energy Agency...

INTRAVAL was set up as an international project concerned with the use of mathematical models for predicting the potential transport of radioactive substances in the geosphere. Such models are used t...

The Probabilistic System Assessment Group (PSAG) was established by the RWMC in January 1985 (originally under a different name) to help co-ordinate the development in OECD member countries of probab...

The international study INTRAVAL addressed the validation of models of the transport of radioactive substances through groundwater in the geosphere. The project started in 1987 on the initiative of t...

The development of radiation protection and of nuclear safety concepts have been somewhat separate. Traditionally, radiation protection has mainly focused on the protection of workers and members of ...

Low-level radioactive waste (LLW) arises in the normal operation of nuclear power plants and fuel cycle facilities, as well as from the use of radioactive isotopes in medicine, industry and agricultu...

The NEA Radioactive Waste Management Committee (RWMC) has underscored the environmental and ethical basis for geological disposal as well as its technical feasibility in a number of previous collecti...

La réglementation de la sûreté à long terme du stockage géologique des déchets radioactifs pose des défis particuliers en raison des vastes échelles de temps concernées. Ce rapport a été préparé afin...

As national geological disposal programmes progress towards implementation, the concept of “optimisation” and related requirements are receiving increased attention. Exchanges within NEA expert group...

Key concepts of radioactive waste management, such as safety, risk, reversibility and retrievability, carry different meanings for the technical community and for non-technical stakeholders. Similarl...
