The Dutch Institute for Fundamental Energy Research (DIFFER) is a research lab that is utilizing its device, Magnum-PSI, to test and develop materials that can withstand the extreme conditions inside future fusion reactors. The institute is exploring self-healing liquid metal layers as a potential solution for reactor wall protection. These layers can flow across a mesh structure, filling voids and restoring the protective layer when damaged. This self-repairing property can extend the reactor’s lifespan and reduce maintenance. DIFFER is also working on designing stable mesh supports for controlled flow and selecting suitable metals with high melting points and low volatility. The institute’s specialization in testing materials under intense heat and particle impacts makes it a crucial partner in the global efforts to realize fusion energy. Through Magnum-PSI, DIFFER is conducting experiments that simulate the harsh environment of fusion reactors, allowing researchers to analyze the behavior of materials like tungsten, which has a high melting point. The institute’s work has significant potential to contribute to the development of fusion energy.
Advanced, self-healing materials can safeguard fusion reactors against heat-induced damage.
