16th Information Exchange Meeting on Actinide and Fission Product Partitioning and Transmutation (16IEMPT)

The NEA is organising the 16th Information Exchange Meeting on Actinide and Fission Product Partitioning and Transmutation (16IEMPT) on 24-27 October 2023. The meeting will be held at the NEA offices in Boulogne-Billancourt, France, in collaboration with the International Atomic Energy Agency (IAEA).

The event is supported by the EU-funded PATRICIA project, the French Alternative Energies and Atomic Energy Commission (CEA), MYRRHA and the Japan Atomic Energy Agency (JAEA).  

Advanced nuclear fuel cycles to improve the safety, sustainability and economics of nuclear energy are under development internationally. Partitioning and Transmutation (P&T) is one of the candidate technologies to help reduce the heat, radiotoxicity and volume of radioactive waste. Recent developments indicate the need for embedding P&T strategies into advanced fuel cycles considering waste management and economic issues.

To give experts a forum to present and discuss state-of-the-art developments in the field of advanced nuclear fuel cycles and P&T, the NEA has been organising biennial information exchange meetings on actinide and fission product partitioning and transmutation since 1990.

Key dates

31 March 2023 Start of extended abstract submission
31 May 2023 Close of extended abstract submission
28 July 2023 Notification to authors
31 July 2023 Start of registration
15 September 2023 Close of registration
24 October 2023 Start of the 16IEMPT
27 October 2023 End of the 16IEMPT

The meeting will address scientific, as well as strategy/policy developments in the field of advanced fuel cycles and P&T. Different sessions will be organised to cover the following topics:

  1. International and national programmes: overview of national programmes in the field of advanced fuel cycles and P&T and activities carried out in international organisations
  2. Fuel cycle strategies and scenarios: scenario analyses, including economic aspects, for advanced fuel cycles and P&T
  3. Advanced reactors and accelerator-driven systems: coolants, physics, infrastructures, design and technology, flexibility, performance and safety
  4. R&D infrastructures for advanced fuel cycles and P&T
  5. Modelling and data: codes and data for advanced reactors, verification, in support of modelling, multiphysics...
  6. Advanced fuels for Pu management and MA transmutation: advanced fuel fabrication, handling and transportation, irradiation, characterisation, performance, PIE
  7. Advanced nuclear fuel recycling: aqueous and pyro separation processes for advanced reprocessing, minor actinide and fission product partitioning, including MSR systems
  8. Waste management for future nuclear fuel cycles: advanced waste forms, waste management strategies (including secondary wastes)
  9. Innovative utilisations of actinides and fission products: other uses of products or waste materials from advanced fuel cycles, isotopes for space power or medical use...

The meeting will consist of plenary sessions covering the technical subjects mentioned above. More details will be announced in due course.

Guidelines and registration

Extended abstracts

All participants willing to present a contribution (oral or poster) should submit an extended abstract (1-5 pages) by completing the submission form. A template with instructions is available in the download section.

Please note that you will need to log in using your NEA account or to pre-register if you do not already have one.

All accepted extended abstracts will be made available to the participants at the meeting. The official proceedings will be published afterwards.

Extended abstracts already submitted 

To ease and harmonise the submission and review process, all authors who submitted extended abstracts before March 2023 are kindly asked to resubmit them (after update, if needed) by completing the submission form.

Copyright form

All authors are invited to fill in, sign and submit the copyright form when submitting their extended abstract. The form is available in the download section.

Early-career scientists

Contributions from early-career scientists (aged under 35) are highly encouraged. The best extended abstracts will be chosen for oral presentation and the authors will be invited to co-chair some sessions.


All participants (presenters and non-presenters) planning to attend the meeting will be invited to complete the registration form. Registration will open in July 2023.

Further information


No registration fees will be charged. 


The meeting will be held in person at the NEA offices in Boulogne-Billancourt, France.

Working language

The working language will be English.


The proceedings of the event, gathering all the extended abstracts, will be published after the meeting.
