The radiation dose rate emitted by spent fuel assemblies is a crucial parameter within the framework of proliferation resistance, and its accurate determination is hence of paramount importance. Recent calculations have shown some discrepancies with historical results for pressurised water...

The disposal of long-lived radioactive waste in a deep geological repository (DGR) is a scientifically and technically credible solution that meets the need for long-term safety without reliance on active monitoring and management. Nevertheless, it is important to assess the potential risks that...

This report aims to highlight the needs of integral experiments in the field of nuclear criticality safety, and to identify the available experimental facilities where such experiments could be performed. In order to identify existing experimental needs, the NEA surveyed international nuclear...

This report compiles and shares some of the lessons learnt from implementing post-Fukushima actions related to human and organisational factors (HOF), including at nuclear facility operating companies, technical support organisations, research institutions, and regulatory authorities. It...

Knowledge of basic nuclear physics data is essential for the modelling and safe operation of all types of nuclear facilities. The de facto international standard format, Evaluated Nuclear Data File 6 (ENDF-6) format, was designed originally for 1960s era punch-card readers. The replacement of...

With an electricity system defined by high shares of hydropower, large capacity for interconnection with its neighbours and low carbon intensity, Switzerland is well positioned to attain its objective of net zero carbon emissions by 2050. However, the exact pathway remains the subject of...

Following the accident at the Fukushima Daiichi Nuclear Power Plant, many countries began funding research and development on nuclear fuel designs with enhanced accident tolerance (ATFs). ATFs have improved designs, materials and performance features compared with those of the current generation...

Nuclear energy is an important source of low-carbon electricity and thus plays a significant role in avoiding carbon emissions. It has the potential to decarbonise the global energy sector even further by also providing heat for industrial applications and residential heating, which both...

Ten years after the Fukushima Daiichi Nuclear Power Plant accident, many lessons have been learnt that have helped improve preparedness for nuclear emergencies and awareness of the global risks that such accidents can entail. This includes a number of long-lasting, multidimensional impacts on...
