Tritium breeding technologies: validation at DONES

15 oct 2026, 11:00

Main Auditorium (CIEMAT)

107. IFMIF-DONES as a key facility for HEXA breeding blanket qualification

Sr. Jacobo Zegrí Reiriz (Lead of Tritium Breeding Blanket at Gauss Fusion GmbH)

15/10/26, 11:30

Gauss Fusion is an industrial fusion company based in Garching, Germany. The company is developing the system architecture and critical enabling technologies required to make fusion power plants buildable, maintainable and deployable. “GIGA”, Gauss Fusion’s gigawatt-class fusion power plant concept, provides the architecture baseline to enable a targeted integrated framework for identifying,...

122. Recent Progress in Kyoto Fusioneering's R&D on Fusion Blanket Components and Materials for IFMIF-DONES Testing

Sr. Mario Oliver (Kyoto Fusioneering UK Ltd.)

15/10/26, 11:45

In the development of breeding blankets for fusion power plants, it is crucial to create material irradiation environments that reproduce fusion-relevant neutron spectra and fluences. IFMIF-DONES will provide an irradiation environment with neutron energies and fluxes relevant to fusion applications, enabling the assessment of materials and components under conditions closer to those expected...

105. TBU-WCLL radiation parameters assessment on IFMIF-DONES facility

Fernando Mota (Laboratorio Nacional de Fusión, CIEMAT)

15/10/26, 12:00

The Water-Cooled Lithium-Lead (WCLL) Breeding Blanket (BB) is one of three concepts actively developed by EUROfusion as driver blanket candidates for the EU Fusion Demonstration Plant (EU-FDP). This reference design employs liquid PbLi eutectic as breeder material and water as coolant, integrated with EUROFER structures. Despite significant design progress, critical technologies—including...

110. LBVM geometrical configuration for permeation control optimization

FERNANDO ARRANZ (CIEMAT)

15/10/26, 12:15

One of the most relevant objectives of the Liquid Breeder Validation Module is the study of tritium permeation through structural materials considered for future nuclear fusion power plants, as well as the effect of permeation barriers applied to these materials.
Permeation is mainly affected by the temperature of the wall through which it occurs, following Arrhenius-type relationships....

118. Nuclear Reaction Analysis as a Qualification Tool for Hydrogen Isotope Retention in Lithium-Based Functional Materials for Fusion Applications

Dr. Norberto José Sobral Catarino (IPFN, University of Lisbon, Instituto Superior Técnico)

15/10/26, 12:30

The development of fusion reactors beyond ITER requires the qualification of functional materials capable of operating under intense particle and neutron irradiation while maintaining their structural and functional properties. Lithium-based materials are attracting increasing interest for advanced fusion technologies, including liquid-metal plasma-facing concepts [1], due to their ability to...
