One of the key areas in fuel safety is the analysis of fuel behaviour under reactivity-initiated accident conditions. Reactivity-initiated accident fuel rod codes have been developed for a significan...

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 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...

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...

Energy markets will be significantly different in the future. The electricity generation system is becoming more diverse with the development of energy-related technologies including renewable energy...

Nuclear power plants are used extensively as base load sources of electricity. This is the most economical and technically simple mode of operation. In this mode, power changes are limited to frequen...

Climate change will create specific risks and challenges for nuclear power plants and the electricity system as a whole. Extreme weather events caused by climate change – such as floods, storms, heat...

Understanding the accident at the Fukushima Daiichi Nuclear Power Plant is important for safe and timely decommissioning of the reactors. This objective, together with the development of better compu...

Experimental facilities in nuclear energy are key to addressing safety issues. The recent loss of some critical infrastructure, from facilities to industry expertise, has therefore become a concern f...

The existing nuclear fleet remains the largest low-carbon source of electricity generation in OECD countries. In 2021 the average nuclear power plant had already been operating for 31 years and some ...

The world’s nuclear power reactors are ageing, with the majority approaching the end of their planned operational lifetimes in the coming years. The adequacy of funding for decommissioning and radioa...

As the Fukushima Daiichi nuclear power plant (NPP) accident illustrates, many challenges have to be faced in maintaining safety over the long term in a damaged NPP following a severe accident. These ...

Small Modular Reactors (SMRs) are gaining recognition among policymakers and industry players as a promising nuclear technology. SMRs can be defined as nuclear reactors with a power output between 10...

Nuclear Energy Data is the Nuclear Energy Agency’s annual compilation of statistics and country reports documenting nuclear power status in NEA member countries and in the OECD area. Information prov...

The Information System on Occupational Exposure (ISOE) is jointly sponsored by the Nuclear Energy Agency (NEA) and the International Atomic Energy Agency (IAEA). Since 1992, ISOE has provided a forum...

The decisions made about protective actions of people and the environment in situations involving exposure to ionising radiation have tended to be driven by subjective judgements about the health ris...

This volume is the 14^th in the OECD Nuclear Energy Agency (NEA) Chemical Thermodynamics series. It is the second update of the critical reviews published, successively, in 1992 as Chemical Thermodyna...

Uranium is the raw material used to produce fuel for long-lived nuclear power facilities, necessary for the generation of significant amounts of low-carbon electricity and other uses, such as heat an...

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...
