Kyoto Fusioneering and Amentum Announce Strategic Collaboration to Accelerate Global Fusion Commercialisation
Kyoto Fusioneering (KF), a world‑leading developer of engineering systems and technologies essential to commercial fusion power plants, has entered into a Memorandum of Understanding with Amentum, a global leader in engineering, programme management, and advanced energy technologies.
The agreement establishes a strategic framework for international cooperation across the United Kingdom, Japan and the United States, strengthening both organisations’ roles in advancing fusion energy commercialisation.
Under this agreement, KF and Amentum intend to pursue joint opportunities across major public and private fusion programmes, integrating KF’s confinement-agnostic fuel cycle, breeding blanket and plasma heating systems and its experience integrating them into fusion plant designs with Amentum’s established, technology-agnostic fusion engineering capability and expertise in systems engineering, plant integration, nuclear safety, digital engineering and programme delivery.
Together, KF and Amentum will explore opportunities to combine fusion engineering and expertise with advanced digital and AI-driven engineering and programme delivery tools. This has the potential to optimise design cycles, improve predictive performance and accelerate the transition from experimental systems towards commercially viable fusion plants.
Kiyoshi Seko, president and COO of Kyoto Fusioneering
“Building a fusion power plant will depend on collaborations like this one. Amentum brings nuclear engineering and programme delivery experience at the scale fusion programmes will need as they move towards construction. We look forward to working with the Amentum team to combine that experience with our fuel cycle, breeding blanket and plasma heating systems on programmes in the United Kingdom, Japan and the United States.”
Mark Whitney, president of Amentum’s Energy and Environment business
“The Amentum and Kyoto Fusioneering partnership comes at a pivotal moment for the global fusion energy sector. By combining Amentum’s capabilities with Kyoto Fusioneering’s advanced fusion technologies, we can help address the engineering and delivery challenges required to move fusion from experimental systems towards commercially viable power plants. This collaboration represents a shared commitment to accelerating the delivery of clean, secure and scalable fusion energy.”
