    Brief

    Nuclear Restoration Services Ltd (NRS) is conducting preliminary market engagement for the potential procurement of design, manufacture, and testing services for plant and equipment to support a new Waste Transfer Corridor at the Dounreay Site in Caithness, Scotland. This Prior Information Notice is for information and engagement purposes only and does not represent a commitment to award a contract. Background: Dounreay is one of the UK's most complex nuclear decommissioning sites, combining legacy experimental facilities with constrained conditions on an active, regulated nuclear site. NRS is decommissioning legacy Shaft and Silo Intermediate Level Waste (ILW) storage facilities as part of a multi-year programme. Scope: The procurement will cover engineering design, manufacture, and factory acceptance testing (FAT) of plant and equipment for the new Transfer Corridor. Additional requirements may include operational and maintenance manuals, delivery, and post-FAT storage. The equipment will enable safe waste transfer from the Silo to a new waste processing facility via the Transfer Corridor, supporting construction and commissioning of these facilities. Note: Construction of facilities and installation of equipment are excluded from this procurement. Delivery approach and scope remain under development and may change. Interested suppliers are encouraged to engage with NRS during this preliminary market engagement phase.
