## Summary

The procurement process, managed by the United Kingdom National Nuclear Laboratory Limited (UKNNL), is currently at the planning stage with an upcoming engagement milestone scheduled for 17 August 2026. This initiative involves the purchase of laboratory equipment—specifically hoppers, screwfeeders, vibratory feeders, and rotary barrels—to support nuclear powder technology research and development. The equipment will be used within a laboratory fumehood in Warrington, UK. The total contract value is anticipated to be £150,000, with procurement taking place under the "goods" category. Interested parties must consider the flexibility and technical specifications required for these materials to be able to submit competitive bids.

This tender offers a growth opportunity for suppliers in the laboratory, optical, and precision equipment sectors, as well as those in machining and fabrication work. Small to medium enterprises (SMEs) may find this opportunity particularly suitable due to the equipment's bespoke requirements and flexibility demands. Suppliers capable of designing custom solutions or offering off-the-shelf products that meet the provided specifications will be well-positioned to compete. The emphasis on flexibility—such as interchangeable components and variable operational parameters—indicates a preference for innovative solutions, making this a promising opportunity for businesses keen on expanding their footprint within the UK's scientific research infrastructure.

## Notice

UKNNL is looking to purchase four pieces of equipment to support research and development activities relating to nuclear powder technology. The four pieces of equipment are Hoppers, Screwfeeders, Vibratory Feeders and Rotary Barrels. The equipment is required to be used within a laboratory fumehood. The fumehood has a 600 mm by 1200 mm (Depth x Width) footprint. Ideally, these technologies can be handled easily, making quick and easy switching of equipment into and out of the fumehood. It is expected that these technologies can handle/hold up to 1 litre of powder and performance over a short fixed duration (e.g. 1 l h-1 max flow rate). UKNNL would like to hear from suppliers who are able to design and machine these items to the suitable scale, or suppliers who have off the shelf solutions, meeting the sizing requirements stipulated. UKNNL are exploring the option of purchasing all four items from a singular supplier or from a multiple suppliers. Flexibility of equipment must be considered where possible, whether this is screw size in a feeder, or interchangeable hopper outlets. The key here is to allow UKNNL's powder capability to test as many scenarios as possible against different powders. Table 1 below captures where flexibility is of interest for different technologies. Hoppers * Interchangeable Hopper outlets, specifically different outlet diameters * 12.5 cm and 10 cm Hopper diameters * Coupling for outlet valve attachments Screwfeeders * Interchangeable screws with: o Different configurations o Varying pitches * Variable rotation speeds Vibratory feeders * Variable vibration frequency * Variable angles of chute * Variable chute geometries (e.g. cylindrical, rectangular) Rotary Barrels * Variable rotational speeds * Variable angles of incline * 12.5 cm and 10 cm diameters * Interchangeable 'inserts' (e.g. lifters, baffles) All * Where possible (and compatible), transparent materials to provide visual feedback
