The NEA organised a virtual workshop on 7 October 2021 to explore the opportunities and challenges associated with High-temperature reactors for industrial heat applications.

The Generation IV International Forum (GIF) held its semi-annual Policy Group meetings from 18 to 28 October 2021 to review and discuss its ongoing work and activities.

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 NEA Working Group on the Safety of Advanced Reactors (WGSAR) held its biannual meeting via video conference on 21-23 April 2021, welcoming a new member representing Poland’s National Centre for N...

The Committee on Nuclear Regulatory Activities (CNRA) is an international committee created in 1989 to guide the NEA concerning safety in the regulation, licensing and inspection of nuclear installat...

The NEA organised a virtual workshop in collaboration with the Canadian Nuclear Safety Commission (CNSC) on 14-18 December 2020 to discuss the best regulatory practices that the nuclear sector can ad...

Generation IV International Forum (GIF) updates 

The quality of the isotopic composition of plutonium fuel degrades as the number of recycles increases in thermal reactors, requiring an increase in the total loading necessary in mixed plutonium-ura...

This study analyses the need for adjustments in or new developments of the fuel cycle for Small Modular Reactors.

The study will investigate what are the cogeneration capabilities of various advanced reactor designs, as well as the flexibility they may have to switch from electricity generation to heat productio...

The working group will be responsible for the programme of work in the CNRA regarding regulatory activities in the primary area of advanced reactors and associated installations. The term “advanced r...

Questions relating to the space, time end energy distribution of neutrons and radiation in different media are the domain of reactor physics.

NEA Working Group on the Safety of Advanced Reactors (WGSAR) meeting, 9‑11 October 2019

As part of the work of the NEA Expert Group on "advanced reactor systems and future energy market needs”, a workshop was organised on 4 September 2019 with the objective of better understanding how t...

NEA News is the professional journal of the Nuclear Energy Agency (NEA). It features articles on the latest nuclear energy issues concerning the economic and technical aspects of nuclear energy, nucl...

The workshop was held at the NEA Headquarters in Issy-les-Moulineaux on 28-29 May 2013, and gathered nearly 30 invited experts from 10 NEA member countries (Belgium, Finland, France, Japan, Republic ...

The NEA has studied multiple recycling issues associated with various reactor systems fuelled with mixed-oxide (MOX) and published a series of computational physics benchmarks. This has led to improv...

This report provides an overview of experimental facilities that can be used to address nuclear safety research issues in OECD member countries, and identifies priorities for organising international...

Although the recycling of plutonium as thermal mixed-oxide (MOX) fuel in pressurised water reactors (PWRs) is now well-established on a commercial scale, many physics questions remain. The main quest...

Studies on fast reactors have historically concentrated on their capability to use plutonium produced in thermal reactors as initial fuel, and subsequently their capacity to produce electricity while...

Attitudes towards plutonium management vary from country to country and from utility to utility: some regard plutonium as a liability and others as a valuable source of energy.

The purpose of this st...
