U.S. and Japan Prioritize Fusion Development in Technology and Prosperity Deal
On October 28, the U.S. and Japan finalized a Memorandum of Cooperation (MOC) regarding the Technology and Prosperity Deal, an agreement to strengthen bilateral collaboration across cutting-edge science and technologies. The commitment includes provisions for fusion as an industrial and economic imperative for two of the world’s largest economies.
The two governments committed the following:
Unlocking the Promise of Fusion Energy
“Appreciating the potential for fusion technologies to deliver safe, resilient, and abundant energy, the Participants intend to work together to facilitate a world-leading fusion industrial ecosystem. Areas of collaboration include supply chains for magnets and high-power components, fusion fuel cycle and blanket integration systems, neutronics modeling, and fusion materials. Participants intend to collaborate on fusion research and development, including the JT-60SA test facility, with the goal of supporting the commercial development and deployment of fusion reactors.”
The MOC moves beyond research to support the commercial development and deployment of fusion machines. The agreement is an important signal to the global market; by aligning efforts, the U.S. and Japan are taking concrete steps to create a robust environment for the fusion industry.
It outlines areas of collaboration that will benefit fusion in both countries:
- Supply Chain Resilience: Participants will work together on securing and developing supply chains for critical components, including high-power components and superconducting magnets – key for various types of commercial fusion machines.
- Core Systems Development: The deal highlights joint work on the fusion fuel cycle and blanket integration systems, which are needed for various approaches to breed tritium fuel and efficiently extract heat for power generation.
- Advanced R&D: The countries will collaborate on foundational scientific and engineering challenges, such as neutronics modeling and fusion materials development, enhancing machine longevity and safety.
- Joint Facility Utilization: The agreement supports R&D collaboration involving Japan’s advanced JT-60SA test facility, showing a commitment to utilizing existing, large-scale infrastructure to de-risk next-generation designs.
The FIA looks forward to continue working with government and research agencies in both nations to implement the MOC’s objectives and reinforce the positions of the U.S. and Japan in the global fusion economy.
