Summary of the contracting process

UK Research & Innovation (UKRI) sought an upgrade to the Siemens PLC-based cryogenic control system for Target Station 2 (TS2). The system is the central component supporting neutron moderation, so the requirement concerns specialist control-system engineering for cryogenic scientific infrastructure. The procurement was categorised primarily as goods, with associated electronic supplies and installation services for equipment such as steam generators, turbines, compressors and burners. Delivery was required in the United Kingdom. The work would suit suppliers able to integrate, upgrade and install Siemens PLC control technology in a demanding research or industrial environment, particularly where reliable operation of cryogenic systems and neutron-moderation infrastructure is relevant. UKRI, based in Swindon, Wiltshire, was the buying organisation.

The process reached tender: UKRI invited offers through an open procedure. The enquiry deadline was 30 June 2026 at 17:00, and the tender submission deadline was 17 July 2026 at 17:00. The contract period was 24 August 2026 to 24 August 2027. The estimated value was £500,000 excluding VAT, or £600,000 including VAT. Bids could be submitted electronically in English. The single lot was assessed on technical and quality considerations, weighted at 70%, and price, weighted at 30%. The tender has since been cancelled, and the award was cancelled because UKRI decided after internal discussion that no contract would be awarded. The published process therefore does not represent a current route to contract.

This opportunity was suited to small and medium-sized enterprises as well as larger specialist contractors. Strong candidates would have needed capability in Siemens PLC-based control-system upgrades, cryogenic control engineering and the integration of electronic equipment with existing scientific or industrial assets. Relevant experience in systems supporting neutron moderation, or in comparable high-reliability research, energy or process environments, would have been useful. Suppliers would also have needed to provide installation services alongside equipment supply, implying the ability to manage both engineered hardware and on-site implementation. The technical and quality weighting made demonstrated engineering competence, integration methodology, reliability and delivery approach more important than price alone. The requirement would therefore have been most relevant to specialist automation, process-control, cryogenic engineering and scientific-infrastructure firms, including capable SME delivery teams.
