Summary of the contracting process

The UK Atomic Energy Authority is initiating a procurement process for a tender titled "THOR magnet cooling system," which is in the planning stage. Located at the Culham Science Centre in Oxfordshire, the authority focuses on the development of cooling systems critical for the CHIMERA test rig aimed at emulating a nuclear fusion reactor environment. The relevant industry categories include engineering design services, recirculating coolers, water coolers, cooling-water pumps, refrigeration coils, construction work for cooling towers, and installation work of cooling equipment. Key dates for this procurement include a milestone for market engagement scheduled for 26th June 2026, with the procurement process set to advance further on 3rd July 2026. The tender process is poised to conclude with contract work starting from 7th August 2026 through to the end of December 2026.

This tender offers substantial opportunities for businesses specialised in cooling technology and engineering services, especially those with capabilities in designing and installing complex cooling systems. Small and medium-sized enterprises (SMEs) are particularly encouraged to participate, as the suitability criteria accommodate their involvement. The gross value of the tender is pegged at £120,000, creating a viable opportunity for businesses aiming to expand their operations in the field of advanced engineering solutions for energy applications. Companies adept in the sector and seeking to contribute to the pioneering field of nuclear fusion technology will find this opportunity to be aligned with their growth ambitions.

Notice Title

THOR magnet cooling system

Notice Description

CHIMERA is a planned test rig that aims to replicate the conditions inside a nuclear fusion reactor, excluding the radiation component. Magnets (static and pulse/vertical field magnet) are to be installed as part of the first phase of CHIMERA's installation (dubbed "THOR"). Cooling systems will need to be implemented to continually maintain four cryogenic compressors for the static magnet (SM), and to cool the VFM.
