SMaRRt is a dedicated event at the European Research Reactor Conference (RRFM) 2026, created to strengthen collaboration between developers of Small and Advanced Modular Reactors (SMRs/AMRs) and the research reactor community.
As advanced reactor technologies move from design to deployment, the exchange of expertise and the use of existing research infrastructures are becoming essential to overcoming shared challenges.
The event will focus on the key technical challenges associated with the development and qualification of reactor technologies.

Info Point
SMaRRt 2026 – Venue
SMaRRt 2026 will take place in the Hilton Garden Inn Leiden.

Willem Einthovenstraat 3
Oegstgeest, 2342 BH, Netherlands
The Leiden Hilton Garden Inn is located just 15 minutes from Leiden city centre and central station (see Google Maps).
GETTING THERE
Amsterdam Airport Schiphol is just 15 minutes from Leiden by direct train (see Google Maps). Leiden Central Station is one of the ten largest in the Netherlands and offers convenient connections to high-speed rail services to Belgium, France, Germany, and the United Kingdom. The city is also ideally situated between the A4 and A44 motorways, providing easy access to international road networks across mainland Europe and the UK via North Sea ferry connections.
Leiden, the City of Science
Leiden is a historic and vibrant city known for its rich scientific and cultural heritage. Home to the Netherlands’ oldest university and the country’s largest life sciences cluster, the Leiden Bio Science Park, the city is a hub for innovation and research. With its charming canals, centuries-old monuments, and world-class museums, Leiden offers a unique setting for international conferences and is among the top five congress destinations in the Netherlands.

Call for Papers
SMaRRt is a dedicated event at RRFM 2026, created to strengthen collaboration between developers of Small and Advanced Modular Reactors (SMRs/AMRs) and the research reactor community. As advanced reactor technologies move from design to deployment, the exchange of expertise and the use of existing research infrastructures are becoming essential to overcoming challenges.
The event will focus on the key technical challenges associated with the development and qualification of advanced reactor technologies. It will provide a platform for in-depth contributions from the community—highlighting practical experience, ongoing projects, and cutting-edge research that drive innovation forward.
Call for Contributions – Share Your Work!
We invite all members of the SMR/AMR and research reactor communities to contribute to the discussion by presenting current projects and experience related to:
- Testing in extreme conditions (High-temperature, intense radiation, challenging environment testing)
- Expertise/experiences in the qualification of materials and fabrication technologies
- Building the future operating organisation of innovative reactors
- Use of advanced and innovative concepts, moderators, coolants and innovative combinations
- Advances in instrumentation, modelling and simulation that can reduce time & cost of fuel development
-
Safety approach and regulation
Interested in joining the discussion? Submit an abstract for a presentation slot in the technical sessions of SMaRRt. Don’t miss this opportunity to share your expertise and connect with key players from both the SMR and research reactor communities!
