Strategic Objectives
• Master the metallurgy of refractory metals like tungsten and beryllium.
• Understand the atomic-level degradation caused by intense neutron flux.
• Explore cutting-edge solutions for heat exhaust and thermal management.
• Identify the material breakthroughs required for the success of ITER and DEMO.
The Core Challenge
Nuclear fusion promises infinite power, but the 'first wall' materials currently melt, erode, and fail under the most extreme conditions in the known universe.
