On March 14, 2025, the Sustainable Nuclear Energy Technology Platform (SNETP) hosted its 3rd Project Portfolio Webinar, showcasing advancements in nuclear technology with a focus on three major SNETP-labeled research projects: LESTO, ESFR-SIMPLE, and TREASURE.

These projects, all under the ESNII pillar, are working towards the development of safer, more efficient, and sustainable Generation IV reactor technologies, each with a distinct focus on enhancing the future of nuclear energy in Europe.

Key Takeaways from Each Project

LEad-cooled Fast Reactor Safety and TOols (LESTO)

Focuses on improving Lead-cooled Fast Reactor (LFR) technology through passive safety systems, advanced simulation tools, and material durability research. It also explores integrating LFRs with renewable energy sources, including hydrogen production.

European Sodium Fast Reactor – Safety Improvements through Modelling, Prototyping, and Large-scale Experiments (ESFR-SIMPLE)

Aims to enhance Sodium Fast Reactor (SFR) safety and efficiency, including SMR adaptations, AI-driven monitoring systems, and innovative passive safety features like advanced decay heat removal.

Towards the European ALLEGRO Ultimate Reactor (TREASURE)

Works on the Gas-Cooled Fast Reactor (GFR) technology, particularly the Allegro Demonstrator, addressing challenges like coolant loss prevention, material durability, and heat storage for improved grid stability and high-temperature applications like hydrogen production.

Common Themes

The webinar highlighted three key themes across the projects:

  • Nuclear Safety: Focus on passive safety systems, material resilience, and advanced monitoring to improve reactor safety and efficiency.
  • Sustainability: Innovations aimed at reducing nuclear waste, improving fuel cycles, and supporting Europe’s clean energy transition.
  • Collaboration: Strong emphasis on European cooperation to accelerate innovation and ensure safe, efficient deployment of Generation IV technologies.

Looking Ahead

The webinar concluded with a productive Q&A session that highlighted the shared vision of advancing Generation IV nuclear technologies to support Europe’s transition to safe, clean, and efficient nuclear energy. This forward-thinking approach is crucial to securing a sustainable and energy-independent future for Europe.

Upcoming events, including the SNETP Forum and FISA-RADWASTE Conference in May 2025, will further discussions on nuclear advancements and cross-project collaborations.

Join us for the next webinar, in April 2025, showcasing cutting-edge projects focused on enhancing the safety, longevity, and operational efficiency of nuclear reactors across Europe. More information coming soon!
