The Fusion Energy Race: ITER to KSTAR — 2026-10-01
Commonwealth Fusion Systems locked in a record high-temperature superconducting tape supply deal this week, while China's BEST tokamak entered critical assembly phase and the U.S. pushed $135 million in fusion commercialization funding. ITER's path to 2039 deuterium-tritium operations remains on track despite decade-plus delays from original targets.

Top developments
Commonwealth Fusion Systems Secures Historic Superconductor Supply Chain
Commonwealth Fusion Systems signed a record supply agreement with Japan's Fujikura for high-temperature superconducting (HTS) tape—enough to span 6,200 miles—as the company prepares to build commercial fusion power plants. The deal represents a major de-risking of SPARC's supply chain and signals growing confidence in near-term commercialization timelines.
CFS Transitions from SPARC to ARC Commercial Plant Design
CFS is advancing detailed design and regulatory planning for ARC, its first-of-a-kind commercial fusion power plant, building on lessons learned during SPARC's demonstration phase. The pathway from proof-of-concept to utility-scale deployment is crystallizing as the company moves toward licensing discussions with the NRC.
China's BEST Tokamak Enters Critical Manufacturing and Assembly Phase
China's Burning Plasma Experimental Superconducting Tokamak (BEST) formally opened its campus in Hefei, Anhui and began assembly of critical main-device components, including toroidal field (TF) coil boxes manufactured by state-owned China National Heavy Duty Truck Group. The move marks BEST's transition from design to engineering endgame, positioning it as a key bridge between experimental research and demonstration fusion reactors.
ARPA-E Commits $135 Million to Fusion Commercialization Programs
The U.S. Department of Energy's Advanced Research Projects Agency–Energy announced $135 million in funding for fusion energy commercialization, supporting multiple pathways including magnetic confinement, inertial confinement, and alternative approaches. The investment signals sustained federal commitment to near-term fusion deployment and reduces reliance on venture funding alone.
China Achieves 100 Million Hydrogen-Boron Fusion Reactions Per Second
China's EXL-50U tokamak reported achieving hydrogen-boron (aneutronic) fusion with sustained reaction rates exceeding 100 million reactions per second, advancing non-traditional fusion fuel pathways that could eliminate neutron-related damage and tritium breeding challenges.
Local view
China (Sohu, 新浪科技): Chinese media coverage highlighted EAST's 20-year operational milestone and BEST's imminent "artificial sun" capability. Articles framed the projects as proof that "controlled fusion may not require waiting 50 years," emphasizing domestic supply-chain independence with locally manufactured TF coil components now in mass production.
South Korea (코리아타임뉴스, MoneyToday): Korean outlets covered the opening of Naju's Global Energy Forum 2026, positioning South Korea as a future fusion hub. Articles noted KSTAR's role in developing "24-hour fusion power plant" technology and emphasized Korea's pivot toward continuous plasma operation research rather than peak performance metrics alone.
Context & numbers
- CFS superconductor commitment: 6,200 miles of high-temperature superconducting tape from Fujikura
- ARPA-E 2026 fusion funding: $135 million across multiple fusion pathways
- China BEST campus: Campus formally opened with TF coil box batch production underway in Hefei, Anhui
- China EXL-50U: 100+ million hydrogen-boron reactions per second sustained
- ITER deuterium-tritium start: Delayed to 2039 (4 years from prior 2035 baseline); full magnetic energy target 2036

On the radar
- ITER Council November meeting: Formal adoption of updated baseline extending through deuterium-tritium operation phase expected
- NRC fusion-machine rule: Final regulatory guidance for fusion licensing anticipated October 2026
- Helion Polaris records: Temperature records by alternative fusion concepts (Helion) mark growing competition in magnetic confinement approaches
- ICF gain repetition: NIF's track record of repeated net-energy-gain shots (5.2–8.6 MJ yields in recent months) suggests inertial fusion moving toward repeatability thresholds needed for commercial viability
