    Brief

    UK Fusion Energy Ltd seeks a contractor to develop comprehensive technical specifications and datasheets for key tritium fuel cycle components of the Spherical Tokamak for Energy Production (STEP) Prototype Plant. This contract requires rationalizing multiple sources of design information and creating standardized, accessible technical guidance for mature equipment including tritium-compatible valves, piping, pressure vessels, catalytic recombiners, molecular sieve beds, vacuum pumps, and depleted uranium storage beds. The specifications must provide sufficient technical depth to enable pre-qualification and early supplier engagement while remaining independent of final plant sizing and detailed interfaces. The contractor will document decision logic for selected design criteria, producing clear guidance that suppliers can interpret and apply during component development. Deliverables will establish a technical baseline for a potential supplier accreditation scheme being considered by UK Fusion Energy Ltd. This work is essential for advancing the STEP prototype toward commercialization by ensuring component specifications meet industry standards and enable effective supplier collaboration.
