DIII-D partners with Kyoto Fusioneering on new power exhaust system
From the Energy digest for 2026-10-15
What happened: The DIII-D National Fusion Facility announced — in the week before the ANS report (published Oct 15, 2026, ~9:06 AM ET) — a public-private partnership with Japan's Kyoto Fusioneering to design, manufacture, install, and operate a new power exhaust system in the DIII-D tokamak, advancing a negative-triangularity approach toward commercialization. The effort builds on the company's partnership with Oak Ridge National Laboratory announced earlier in 2026.
What's genuinely new: A development of the fusion-race thread ("newgen — Fusion race: $10B bill, ENN's H-B groundbreak, UK sprint"), whose record so far holds capital closes, ITER hardware completion (Oct 5), and General Fusion's Oct 8 plasma milestone — this adds the thread's first US-tokamak supplier-hardware entry and a second named US-lab tie (ORNL, then DIII-D) for Kyoto Fusioneering, a new supplier name on the record alongside Japan's Helical Fusion. Negative triangularity as a commercialization vector is stated but uncharacterized in the captured summary.
Watch: install/commissioning timeline for the exhaust system; whether negative triangularity yields dated experimental milestones; further Kyoto Fusioneering expansion across US national-lab infrastructure; any DOE funding framing of the partnership.
