NSG Part 1 and Part 2 Control Lists Updated

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). INFCIRC/254 Part 1 and Part 2 were last published by the IAEA in 2019.

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 2019 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 Control Lists.
