Explanation of the Process for updating the NSG Guidelines and Control Lists


The Nuclear Suppliers Group generally updates its Guidelines and Control Lists every year following its Plenary Meeting and informs of agreed changes to the Guidelines and Control Lists via its website for information purposes. This annual update has (only) a preliminary character.

Every three years, the NSG forwards consolidated changes (three Plenary Meeting decisions) to the IAEA for official publication as part of the INFCIRC series (INFCIRC/254 Part 1 and Part 2). 

States decide whether they implement changes to the Guidelines and Control Lists based on the annual publication of agreed changes to the Guidelines and Control Lists on the NSG website or wait for the IAEA publication.

The timing of implementation may vary across PGs according to national practice though all are encouraged to adopt changes in a timely manner.

At the 2023 NSG Plenary Meeting, the NSG maintained its focus on technical issues important to the implementation of the Control Lists, by exchanging views and agreeing on a number of proposals to clarify and update the NSG Trigger List and Dual-Use List.

The updated NSG Part 1 Trigger List and NSG Part 2 Dual-Use List as agreed by the 2023 NSG Plenary in Buenos Aires, Argentina (July 2023). Two documents explaining the rationale behind the latest changes to the Part 1 and Part 2 Control Lists can be found below.
