## Summary

The procurement process, initiated by UK Fusion Energy Ltd, involves the development of technical specifications for the Spherical Tokamak for Energy Production (STEP) Prototype Plant tritium fuel cycle. This opportunity pertains to the industry category of technical analysis, consultancy, and management services. The procurement process is in the tender stage, with a submission deadline set for 3rd September 2026. The buyer, UK Fusion Energy Ltd, located at Culham Science Campus in Abingdon, is looking to standardise design guidance for tritium components, aiming for delivery in the United Kingdom. The contract, valued at £150,000, utilises an open procurement procedure, engaging suppliers through the Delta e-Sourcing platform.

This tender offers significant business growth opportunities for companies specialising in technical consultancy, particularly those with expertise in tritium fuel cycles. The contract demands comprehensive understanding and rationalisation of tritium design information, making it particularly suitable for businesses skilled in technical and developmental consultancy services. With a high emphasis on technical quality (80% weight), it caters to firms that can provide innovative and technically sound solutions. Moreover, it serves as a potential stepping stone for suppliers seeking accreditation in future schemes considered by UK Fusion Energy Ltd, further enhancing the long-term growth prospects for successful bidders.

## Notice

This contract establishes the requirements for development of a suite of equipment-level, near-preliminary design technical specifications and associated datasheets for key components within the Spherical Tokamak for Energy Production (STEP) Prototype Plant (SPP) tritium fuel cycle. The objective is to produce clear, standardised, and accessible technical design guidance for mature tritium components, presented in a format that enables interpretation and application by suppliers. The specifications shall remain independent of final plant sizing and detailed interfaces, while providing sufficient technical depth to enable objective pre-qualification and early supplier engagement. Developing the specifications will require a supplier to rationalise multiple sources of tritium design information and record the decision logic in selecting design criteria. Equipment for the scope is prioritised and includes tritium-compatible valves, piping and pressure vessels, catalytic recombiners, molecular sieve beds, vacuum pumps and depleted uranium storage beds. The output of this contract could form the technical baseline for a supplier accreditation scheme under consideration by UK Fusion Energy ltd.
