Fusion Researchers Advance Toward Commercial Reactors

Researchers and engineers report accelerating progress toward practical fusion power, driven by recent tokamak milestones, materials research, and AI-enabled controls. In 2025, China’s EAST surpassed the Greenwald density limit, ITER received its final central-solenoid module in September, MIT launched the Laboratory for Materials in Nuclear Technologies in June, and private investment rose from $1.5 billion (2016–2020) to nearly $9 billion (2021–2025), strengthening commercialization prospects.
