For the purposes of this early market engagement, UK Fusion Energy Ltd is seeking responses from suppliers capable of providing engineering and technical knowledge to support complex, safety-critical engineering projects, deliver defined work packages supporting technology demonstration projects and industrialisation activities as described within 6.2. The proposed contract is intended to allow a Partner to support UK Fusion Energy by collaboration with potential other partners on the above work as well as with UK Fusion Energy. UK Fusion Energy is interested in understanding suppliers’ experience operating as a Strategic Partner / Integrator potentially supporting the development and management of a nascent supply chain.
