Event Details

RRFM is the annual meeting point for Europe’s research reactor community, bringing together experts, operators, scientists, regulators, and industry leaders from around the world.

In 2026, we are pleased to welcome you to Leiden, The Netherlands, from 20 to 24 April. 

The conference programme will feature high-level Plenary Sessions and a series of parallel Technical Sessions covering a broad range of topics related to research reactor technology, utilisation, safety, and management. 

 To enrich the experience, RRFM 2026 will offer three technical visits to leading nuclear facilities in the region: 

– NRG PALLAS site in Petten

– TU Delft Reactor Institute

– URENCO enrichment facility in Almelo 

 

In addition, two dedicated meetings will take place during RRFM 2026: 

  • IRIS – the International Radioisotope Supply Chain Meeting, a new global forum for the radioisotope production community to share progress, address challenges, and strengthen supply chains. 
IRIS 2026 International Radioisotope Supply Chain Meeting
  • SMaRRt, a meeting focused on building bridges between SMR/AMR developers and the R&D community to accelerate innovation through collaboration and shared expertise.

Technical Tours

On Friday 24 April 2026 delegates of the Research Reactor Conference (RRFM) 2026 will have the opportunity to participate in three technical tours: 

Technical Tour I – NRG PALLAS site in Petten – FULLY BOOKED

nrg

The NRG|PALLAS site in Petten is one of Europe’s foremost nuclear research centres, hosting the High Flux Reactor and advanced laboratories for materials research and radioisotope production. It plays a key role in supplying medical isotopes, supporting nuclear fuel and materials testing, and developing next-generation reactor technologies through the upcoming PALLAS Reactor.
Participants can choose between three expert-led visits:
  • The High Flux Reactor, one of the world’s most powerful research reactors and a global leader in medical isotope production and materials irradiation;
  • The Hot Cell laboratories, material research location, and radioisotope unpacking and dispatching, where state-of-the-art material research and isotope handling are carried out;
  • The construction site of the PALLAS Reactor, a facility designed to secure Europe’s future isotope supply and support research on fuels, materials, and reactor systems for next-generation nuclear technologies, including SMRs and medical applications.

Technical Tour II – URENCO enrichment facility in Almelo – FULLY BOOKED

Urenco Almelo Site

Urenco is a global supplier of uranium enrichment services and fuel cycle products for power generation.

This guided tour will follow a fixed route through key areas of the site, offering exclusive insights into the uranium enrichment process. Highlights of the visit include:

  • A look inside the control room,
  • The cylinder transport area,
  • The mass spectrometry room,
  • And a view of the centrifuge hall through a secure observation window.

Throughout the visit, informative animations will guide you through the technical aspects of enrichment, offering a deeper understanding of URENCO’s operations and its role in the nuclear fuel cycle.

Technical Tour III – TU Delft Reactor Institute – FULLY BOOKED

The Reactor Institute Delft (RID) operates a unique research facility: the HOR nuclear reactor. It is equipped with six horizontal beam-tubes in two sets of three at opposite sides of the core, mainly used for neutron scattering experiments. The two larger beam tubes are equipped with stacked-mirror neutron guides (neutron guide system) to obtain clean beams of thermal neutrons with low contamination by fast neutrons and gamma rays. The neutron guide system provides 4 neutron beams to the experiment hall, adjacent to the reactor hall. Measuring 25 x 40 m, this hall provides ample space with a low radiation background for beam experiments.

In 2024, a Cold Neutron Source is commissioned, providing cold neutrons to the experimental hall.

Finally, one of the beam-tubes is used by the source of variable-energy positrons (POSH), the positrons being generated by the hard gamma rays hitting the POSH target. These positrons are led into the experiment hall as well.

During the tour we will visit the research facilities in the experiment hall.
