Reducing industrial carbon emissions is one of the most difficult challenges on the path to net zero by 2050 due to the magnitude of greenhouse gas emissions from the industrial sector and technical ...

All credible models show that nuclear energy has an important role to play in global climate change mitigation efforts (e.g. IEA, 2021; BNEF, 2021; IIASA, 2021). Despite clear analyses from many sour...

Hydrogen has the potential to play an important role as a sustainable and environmentally acceptable energy carrier in the 21st century. This report describes the scientific and technical challenges ...

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...

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...

Uranium is the main raw material fuelling all nuclear fission reactors today. Countries around the world use it to reliably generate low-carbon electricity, process heat and hydrogen as part of their...

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...

This handbook makes international guidance on estimating decommissioning costs more accessible by compiling material from two key reports: the International Structure for Decommissioning Costing (ISD...

All low-carbon solutions will be required to achieve the world's net zero targets. Nuclear energy has a role to play in meeting this need. A wave of innovation in small modular reactors (SMRs) is adv...

Small modular reactors (SMRs) are technologies capable of harnessing the energy from nuclear fission reactions to produce heat and electricity with power outputs typically smaller than 300 MWe, with ...

All low-carbon solutions will be required to achieve the world's net zero targets. Nuclear energy has a role to play in meeting this need. A wave of innovation in small modular reactors (SMRs) is adv...

One of the many lessons learnt about nuclear safety over the years has been that human aspects of nuclear safety are as important as any technical issue that may arise. The international nuclear comm...

The NEA Specialist Workshop on Advanced Measurement Method and Instrumentation for Enhancing Severe Accident Management in a Nuclear Power Plant addressing Emergency, Stabilisation and Long-term Reco...

The concept of improving nuclear safety versus maintaining it has been discussed at a number of nuclear regulators meetings in recent years. National reports have indicated that there are philosophic...

Each nuclear power plant, fuel cycle facility and nuclear research and test facility that is operating today will eventually reach the end of its useful life and cease operation. During the period of...

Contracted services are an integral part of the design, construction and operation of a nuclear facility. Changes in the nuclear industry sector, including varied availability of nuclear expertise, t...

Defence in depth (DiD) is a concept that has been used for many years alongside tools to optimise nuclear safety in reactor design, assessment and regulation. The 2011 Fukushima Daiichi nuclear power...

This report provides the results of the fluid structure interaction (FSI) benchmark, which was developed and performed by the designer and engineering company OKBM as part of NEA and ROSATOM activiti...

The Nuclear Law Bulletin is a unique international publication for both professionals and academics in the field of nuclear law. It provides readers with authoritative and comprehensive information o...

Common-cause failure (CCF) events can significantly impact the availability of safety systems of nuclear power plants. For this reason, several Nuclear Energy Agency (NEA) member countries initiated ...

The brochure provides background information about the NEA.

This document is intended to provide regulators, their technical support organisations and industry with a concise review of existing fuel experimental data at reactivity-initiated accident (RIA) and...

The Nuclear Energy Agency (NEA), in co-ordination with the Nuclear Regulation Authority (NRA) of Japan, hosted the “International Conference on Regulators’ Views and Priorities on Nuclear Safety and ...

This report outlines first the safety concerns and the regulatory basis for reactor water level measurement diversity and reliability in participating countries. After that the measurement methods an...

A healthy safety culture has long been considered essential to maintaining high levels of nuclear safety. Although safety goals across countries are similar, the operational realities vary due to a r...
