The procurement type is service-oriented and involves collaboration with potential partners until 2029 for programme stage 2A evaluation.

This tender presents significant growth opportunities for businesses specialising in engineering, particularly those with expertise in tritium processing, systems and controls engineering, prototype design, and manufacturing engineering relevant to Fuel Cycle Systems. It is ideal for businesses that can offer strategic industrialisation and design integration services. Suppliers are encouraged to engage either individually or collaboratively, enabling them to contribute to substantial technology demonstration projects. As the work requires highly specialised skills in engineering services, including mechanical and electrical engineering, companies with relevant technical knowledge and experience in industrialisation activities are well-suited to compete and contribute to these pivotal projects in the fusion energy sector.
