‘Most promising’ nuclear fusion reactor design simulated by US supercomputer

Type One Energy Group used 250,000 computing hours on a Department of Energy supercomputer to design an advanced stellarator fusion reactor that optimizes plasma confinement through precise 3D shaping rather than brute-force approaches. The breakthrough simulations identified the most stable reactor design and accelerated development by at least one year, with the company targeting a 350-megawatt pilot plant by the mid-2030s.
