This Powder—Not Gas—Could Rescue Nuclear Fusion

Posted by in category: nuclear energy

Researchers at Princeton University have found a way to make a tokamak nuclear fusion reactor safer using insulating boron powder. The new research appears in the IAEA journal Nuclear Fusion and comes from Princeton’s U.S. Department of Energy-funded Princeton Plasma Physics Laboratory (PPPL).

A tokamak, like the huge one that will reach 200 million Celsius in China next year, is a nuclear fusion plasma reactor where extremely hot, charged plasma spins and generates virtually limitless energy. The Princeton research examines the way boron powder can prevent one of the fundamental flaws in existing plasma reactor technology.
