## Summary

The contract "DSM to STEP Plasma control" was awarded by UK Industrial Fusion Solutions Limited, based at Culham Science Centre in Abingdon, United Kingdom. The procurement falls under the category of engineering-related scientific and technical services. Though it was procured via a direct method "Below threshold - without competition", significant progress has been made as the stage is marked complete and the contract was signed on 20th December 2024 with an active period from 21st December 2024 to 31st March 2025. The procurement aims to enhance system engineering methodologies for plasma control in fusion power plants, highlighting its strategic importance in the region of UKJ14.

This procurement process presents promising opportunities for businesses specialising in engineering, technical consultancy, and research and development services. Large-scale organisations with expertise in project management and system engineering for complex scientific domains stand to gain the most. The collaboration between UK Industrial Fusion Solutions Limited and TSM Engineering, a supplier based in France, underscores the cross-border business potential in the field of fusion technology, paving the way for innovative solutions and market expansion for skilled suppliers in related technical services.

## Notice

The purpose of this contract is to implement a system engineering methodology, based on the Design Structure Matrix (DSM) approach as defined in a recent paper (ref: [1]), to model plasma control interfaces, both within the plasma and with external plant systems. This will support the development of an interface model for a spherical tokamak based fusion power plant. In turn, this is expected to inform the selection of a tokamak sensor set that meets functional, redundancy and availability requirements for the plasma control needs of the STEP prototype plant.
