## Summary

The procurement process, led by UK Industrial Fusion Solutions Ltd, focuses on the development of a vertically straight fusion blanket segment demonstrator as part of their ongoing STEP programme. This contract, located at the Culham Science Centre in Abingdon, United Kingdom, falls under the engineering works and construction industry category. Currently in the award stage, the tender involves a contract awarded to Kyoto Fusioneering UK Ltd, valued at approximately £238,780. The procurement followed an open procedure, with key deadlines including the standstill period ending on 5th December 2025. The contract period runs from 10th December 2025 to 31st March 2026, aiming to innovate with ferritic-martensitic steels and assess the feasibility of large-scale fabrication.

This tender provides significant opportunities for business growth in the engineering and technology development sectors, particularly for firms experienced in metallurgy and advanced manufacturing techniques. Small and medium-sized enterprises (SMEs) with capabilities in engineering services, construction of complex structures, and those engaged in research and development can find this as a fertile ground for collaboration and expansion. The procurement necessitates expertise in project management, technical methodology, and innovative approaches to construction, making it ideal for businesses focusing on delivering high-quality, cost-efficient solutions.

## Notice

As part of the on-going STEP programme, continued development, learning and understanding of materials and systems is required. As such, the materials team have set out this requirement to better understand the proposed plan for the breeder blankets within the tokomak. This proof of concept, physical scaled demonstrator and broader technology understanding will benefit the programme and allow for further progress to be made. The scaled physical demonstrator that this project will deliver is to demonstrate the manufacturability of ferritic-martensitic steels in the form required to suit the Breeder Blanket design proposed herein. The demonstration will prove the engineering processes and techniques necessary for the scaled demonstrator and will identify feasibility of increased scale-up for manufacture of the large-scale fabrication of breeder blanket segments using Grade 91 steel.
