## Summary

The Nuclear Decommissioning Authority procured research and development and related consultancy services for its Legacy Waste Cave 5 requirement. This is a specialist services contract supporting nuclear decommissioning activity and legacy-waste management. The buying organisation is the Nuclear Decommissioning Authority, based at Herdus House, Moor Row, Cumbria. Delivery is associated with Moor Row, Cumbria, with the requirement also covering the United Kingdom and wider locations including Europe, the Channel Islands, the Isle of Man, British Overseas Territories and elsewhere. The named service category is research, development and consultancy services. The National Nuclear Laboratory was identified as the supplier for this requirement.

The procurement has reached the awarded and completed stage. The Nuclear Decommissioning Authority selected the National Nuclear Laboratory on 3 August 2026. The award value is £638,606.30, and the contract period runs from 1 April 2026 to 31 March 2027. The tender submission deadline was 3 March 2026 at 12:00 UTC. This was a selective procurement using a call-off from a framework agreement, rather than an open standalone competition. The procurement was classified as a services contract and was recorded as complete. The published outcome relates to one supplier and one requirement. No separate lot structure or award scoring criteria is stated in the procurement information.

This award indicates demand from the Nuclear Decommissioning Authority for specialist nuclear decommissioning research and consultancy focused on legacy waste and Cave 5. Suppliers considering comparable future work would need credible technical capability in nuclear waste management, decommissioning research and the consultancy support required to address complex site or facility requirements. Experience of working for nuclear-sector organisations, understanding of the regulatory and safety environment, and the capacity to deliver a technically demanding framework call-off would strengthen a supplier’s position. The stated suitability assessment did not identify this requirement as suitable for SMEs or voluntary, community and social enterprises, so competitors should expect the scale, specialist expertise and organisational capability associated with an established nuclear-sector provider.
