UK4 - Tender Notice
Summary of the contracting process

The UK Atomic Energy Authority is commissioning engineering services to design, manufacture, commission and operate a tritium-compatible test rig. The rig must represent the operating conditions of the Authority’s Vacuum and Impurity Treatment System (VAC-ITS) and be operated at the contractor’s licensed facility. The work also includes examining materials that have been in contact with the test system after operation, with particular focus on polytetrafluoroethylene (PTFE). This combines engineering design and integration with specialist testing and materials examination. The work is for one integrated requirement, rather than separate packages, and the test facility is to be provided by the contractor. The Authority is a central government organisation based at Culham Science Centre in Oxfordshire; the test work is to take place at the contractor’s facility.

The buyer invited offers through an open procedure. The contract is for services, with one lot. The estimated value is £400,000 excluding VAT (£480,000 including VAT). The contract period is 21 December 2026 to 30 April 2027. The deadline for both clarification enquiries and tender submissions was 16 November 2026 at 12:00 UTC; the stated end of the award period is 2 December 2026. Evaluation is weighted 60% for quality and 40% for price. The quality criterion refers bidders to the procurement documents for its detailed requirements. Tender submissions may be made electronically, and the submission language is English.

This opportunity suits engineering contractors able to take responsibility for a complete test rig lifecycle, from design and manufacture through commissioning and operation. Bidders need access to a licensed facility capable of handling tritium and reproducing the relevant operating conditions of the VAC-ITS. The requirement also calls for suitable expertise and facilities to examine wetted materials after testing, particularly PTFE. It is therefore most relevant to suppliers combining nuclear or tritium-related engineering with controlled test operations and materials analysis, or to teams able to bring those capabilities together. The buyer marks the opportunity as suitable for small and medium-sized enterprises. The integrated scope favours suppliers able to coordinate engineering, safe facility operations and post-test examination within a single delivery.
