Preventing tungsten atoms from entering the plasma is one of the biggest challenges of modern nuclear fusion reactors, and researchers at Princeton Plasma Physics Laboratory (PPPL) may have found a solution to fix it.
The discovery, which uses boron powder to shield tokamak walls from the extreme heat of fusion, presents a solid strategy for achieving sustainable fusion energy, per a PPPL, U.S. Department of Energy, press release published on Monday.
“We’ve developed a new way to understand how injected boron material behaves in a fusion plasma and how it interacts with the walls of fusion reactors to keep them in good condition while they are operating,” Florian Effenberg, a staff research physicist at PPPL, said in the press release.
