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...

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

Generation IV International Forum (GIF) updates 

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...

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...

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...

The quality of the isotopic composition of plutonium fuel degrades as the number of recycles increases in thermal reactors. There are in addition incentives to better utilise fuel by increasing the b...

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...

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...

This study will focus on the economic drivers of production costs of Small Modular Reactors.

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

This study will assess the potential opportunities to harmonise and streamline the licensing processes of SMRs.

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 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 ...

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 NEA is organising the Sixteenth Information Exchange Meeting on Actinide and Fission Product Partitioning and Transmutation (IEMPT 16), from 27 June-1 July 2021. The meeting will be held in Russi...

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

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 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...
