3. Current status and challenges of the development of plasma-facing components

Rudolf Neu (MPI for Plasma Physics)

28/07/2025, 13:00

Invited Talk

The severe operating conditions for Plasma Facing-Components (PFCs) in future power-generating fusion devices require the development of advanced materials and components. PFCs must not only withstand high steady state power loads of up to 20 MW/m², but also a high number of thermal cycles and shocks. In addition, the design of PFCs and the selection of appropriate armour and structural...

2. Review of the tungsten thermal conductivity in a fusion power reactor

Sören Möller (FZJ)

Talk

Tungsten is considered a main candidate plasma facing material (PFM) for nuclear fusion power reactors. Its high thermal conductivity is considered a major advantage compared to other PFMs. Under reactor conditions, the thermal conductivity will deteriorate significantly below the 170 W/(mK) usually agreed at room temperature and without irradiation damage. In a fusion reactor, PFMs have to be...

19. Tritium Breeding Testing with an Intense DT Neutron Source

Lucas Jacobson (SHINE Technologies)

28/07/2025, 14:20

Talk

SHINE Technologies operates the Fusion Linear Accelerator for Radiation Effects (FLARE) high flux, steady state, 14 MeV neutron radiation effects testing facility in Janesville, Wisconsin, USA. FLARE is comprised of a neutron generator, a tritium purification system, an irradiation bunker, and related facility infrastructure. SHINE has evaluated the use of the FLARE facility to perform...

8. X-ray and neutron diffraction for characterizing lattice defects in irradiated structural materials

Tamas Ungar (The University of Miskolc, Miskolc, Hungary)

28/07/2025, 13:40

Talk

Structural materials in the nuclear industry operate within harsh environmental conditions. Cooling substances pose corrosion, irradiation produces a high density of lattice defects, and external strains cause fracture. The large density of lattice defects generated by irradiation causes embrittlement, leading to early fracture. The analysis of diffraction peak broadening, called line profile...

20. SHINE’s DT Fusion Neutron Source for Radiation Effects Testing

Ross Radel (SHINE Technologies)

Talk

SHINE Technologies operates the Fusion Linear Accelerator for Radiation Effects (FLARE) high flux, steady state, 14 MeV neutron radiation effects testing facility in Janesville, Wisconsin, USA. FLARE is comprised of a neutron generator, a tritium purification system, an irradiation bunker, and related facility infrastructure. The neutron driver and tritium systems are the same technology...
