Fusion Services

Oxford Sigma has developed a strong reputation offering specialist fusion services to the public and private sectors, assisting in materials and manufacturing, engineering design, and advisory services.

Fusion Materials

The fusion process creates incredibly harsh environments for reactor materials, where they can experience extreme temperatures, high radiation fields (neutrons and gamma rays), and highly corrosive environments (depending on design).

Oxford Sigma partners with both the public and private fusion sector on materials for fusion, enabling fusion reactors to be built in a timely and economically feasible manner whilst minimising technological risks.

Fusion Manufacturing

A major challenge associated with scaling fusion energy up from a scientific experiment to a commercial fusion plant is the manufacturing of large and often complex components. 

Oxford Sigma has expertise in tungsten, steel, exotic alloys, and refractory alloys manufacturing and joining for fusion devices. This covers covers first-wall tiles, divertor tiles, and breeder blanket components.

Fusion Design

Beyond the core fusion process within a reactor, there are a variety of components designed to effectively extract energy, shield sensitive components from the harsh reactor environment and produce fuel. 
Oxford Sigma develops and designs reactor components, including plasma-facing components, tritium breeding blankets, radiation shields and fuel systems, building up from user needs and systems requirements to a manufacturable and commercially relevant outcome. 

Fusion Advisory

The fusion industry is currently expanding at a high rate, requiring the input of external organisations including investors, governments, and the wider supply chain. 

As fusion specialists, Oxford Sigma advises a large range of organisations on the potential opportunities and risks within the fusion energy industry, communicating complex topics to a wide variety of audiences.
