## Summary

The UK Atomic Energy Authority has successfully completed the procurement process for a contract titled "Simulation Software," which pertains to the IT services and software development category, specifically focused on the fusion energy industry. This award notice, dated 3 July 2025, marks the completion of an open procedure aimed at evaluating and developing industry-specific simulation software. This initiative is particularly focused on advancing design and operational efficiencies for fusion reactors. The procurement process had a tender period which concluded on 18 June 2025, with the contract period commencing on 19 June 2025 and ending on 20 June 2025. The total value of the contract amounts to £360,000, awarded to 11 companies across 4 frameworks, ensuring no single company received over £60,000. The services are to be delivered across various regions including the United Kingdom, Europe, and other specific territories.

This tender offers substantial opportunities for businesses, particularly those in the IT services and software development sectors, to engage with the evolving fusion energy industry. Small and medium-sized enterprises, as well as voluntary, community and social enterprises, are encouraged to participate given the project's eligibility criteria favouring these groups. Companies providing expertise in engineering simulation and software development services can greatly benefit from this project, considering the need for innovative solutions to support the design and realisation of commercial fusion power plants. The procurement method's open nature provides an accessible entry point for diverse businesses seeking growth in a high-tech, cutting-edge industry.

## Notice

Industry provides simulation software and methods covering a wide range of capability, deployed across all engineering sectors, much of which will be invaluable for use in the design and operation of fusion reactors in a Fusion energy industry. However, the extent to which existing capability is sufficient to facilitate design and realisation of commercial fusion powerplants is not clearly defined. Industry Simulation Software for Fusion is a multi-year rolling project aiming to define Fusion relevant analysis and simulation case studies and use them as a formal basis to engage industry for evaluation of their simulation software capability and identify development needs. The case studies to be submitted will span the full range of domains relevant to realisation of fusion as an energy source, with a mixture of single and multi-domain scenarios and involving use of a variety of methods and techniques. A total of four case study areas are covered in the procurement exercise which is now complete. 11 companies across 4 frameworks with no company receiving more than PS60k excluding VAT in total. Therefore this is an award notice only and not a call to competition.
