Description Nuclear Restoration Services Ltd (NRS) is undertaking preliminary market engagement, in accordance with the Procurement Act 2023, in relation to the potential future procurement of the design, manufacture and testing of plant and equipment for a waste Transfer Corridor, in support of the decommissioning of the legacy Shaft and Silo ILW storage facilities at the Dounreay Site, Caithness, Scotland. This Prior Information Notice (PIN) is issued for information and engagement purposes only. It does not commence a procurement procedure and does not represent any commitment by NRS to award a contract. Background and Site Context The Dounreay Site represents one of the most complex decommissioning environments in the UK nuclear estate, combining legacy experimental facilities, constrained site conditions, and long term high hazard activities within a live, regulated nuclear site. The Shaft & Silo programme is expected to span multiple years and will require a breadth of requirements including Plant and Equipment for newly constructed facilities. NRS is exploring the ability to contract design and delivery of Plant and Equipment for a newly constructed Transfer Corridor, as part of the overall programme of works Indicative Scope Indicative requirements may include engineering design, manufacture and testing, operational and maintenance manuals, and delivery for the Plant and Equipment. There may also be a requirement for post-FAT storage. These requirements will enable waste to be safely transferred from the Silo to a new Shaft waste processing facility via a new Transfer Corridor, directly supporting their construction and commissioning. Note: The construction of facilities including the Transfer Corridor, and the installation of the plant and equipment, are outside of this procurement. The scope and delivery approach remain under development and may change.
