Research facilities operating advanced tokamaks have demonstrated sustained plasma stability at elevated pressure ratios, marking progress toward viable power-plant scale net-energy gain.
Superconducting Magnetics
The deployment of rare-earth barium copper oxide magnets has allowed experimental reactors to achieve higher magnetic field strengths within smaller physical footprints, significantly lowering facility construction costs.
Materials Degradation Challenges
Engineering focus is shifting toward plasma-facing components capable of withstanding intense neutron bombardment. Developing radiation-resistant tungsten alloys remains essential for continuous plant operation.
