Subsystems, Enabling Infrastructure & Modular Heat
Picks-and-shovels: tritium handling, gyrotrons, breeding blankets, modular fusion-derived neutron sources.
Reactor design
Reactor subsystems supplier (architecture-agnostic)
Core tech focus
Fuel cycles, gyrotrons, breeding blankets
Key milestones
UNITY-1 fuel loop operational (2024). UK CCFE contracts (2025).
Explicitly does not build a reactor. Aims to be the 'TSMC of fusion' — supplying tritium fuel cycles, gyrotrons, and breeding blankets to every primary developer regardless of which architecture wins.
Architecture-agnostic. Every operational fusion plant — regardless of confinement scheme — requires tritium loops, high-heat-flux blankets, megawatt-class gyrotron heating, and power conditioning.
- Tritium handling at commercial throughput is a regulated, IAEA-supervised activity with limited operational precedent.
- Megawatt-class gyrotron commercial supply is dominated by a handful of vendors with multi-year lead times.
- Subsystem cost is largely architecture-independent — commodity scaling benefits every developer.
- Existing revenue streams (medical isotopes, radiography) de-risk capital deployment vs pure R&D plays.
Kyoto Fusioneering recognised early that whichever confinement architecture wins, every plant needs tritium loops, blankets, and gyrotrons. By dominating the picks-and-shovels market, they mitigate the physics risk borne by primary developers. SHINE demonstrates a critical transitional model: monetising fusion-derived neutron generation for industrial radiography and Mo-99 isotopes today, generating cash flow while iterating toward net-energy generation.

Who built Kyoto Fusioneering
Kyoto Fusioneering is the premier "picks and shovels" player of the global commercial fusion industry. Rather than competing to build a reactor core, this elite team focuses entirely on the critical engineering systems required to extract heat and fuel from any successful plasma. Anchored by Dr. Satoshi Konishi, a legendary global authority on tritium fuel cycles and breeding blankets, the team combined forces with deep-tech strategists Taka Nagao, Dr. Richard Pearson, and Dr. Shutaro Takeda. Together, they design and manufacture world-class gyrotrons, heat exchangers, and exhaust systems, supplying vital hardware to almost every major fusion developer worldwide.
