Summary of the contracting process

The public procurement process for the "2025 PVC Containment Items Tender" by Sellafield Limited, a sub-central government public authority, is currently in the tender stage. This procurement focuses on goods within the polythene waste and refuse sacks and bags industry category. The tender includes manufacturing and supplying Polyvinyl Chloride (PVC) containment items, necessary for handling radioactive and toxic materials at Sellafield's site operations in Warrington, UK. Interested parties have until 12th January 2026 to submit tenders, following registration on the NDA OneNDA eCommercial Systems platform via Atamis Project C10247. The outsourcing aims at a sole supplier for a streamlined supply process and reduced environmental impact, offering an estimated contract value of GBP 3,900,000 to GBP 4,680,000, with the contract running from June 2026 to May 2030.

This tender presents a significant growth opportunity for businesses experienced in manufacturing high-quality containment solutions, especially those compliant with stringent safety specifications. Companies skilled in the nuclear sector's demand for robust containment products are well-positioned to benefit. The opportunity to be a sole supplier under the open procedure not only heightens competition but also paves the way for SMEs to expand their portfolio within the nuclear decommissioning supply chain. The demand includes the production of PVC bags, tents, and other related goods, making it suitable for enterprises with capabilities in large-scale PVC production and quality assurance processes.

Notice Title

2025 PVC Containment Items Tender

Notice Description

Sellafield Ltd has a requirement to award a Contract for the manufacture and supply of Polyvinyl Chloride (PVC) Containment Items along with providing technical support for these items in support of Sellafield Ltd site Operations. This notice is to invite interested parties to submit a Tender for this scope of work, which includes information/interface checking, supply of materials, manufacture, assembly, inspection & testing at Contractor's works, packing, provision of documentation for PVC Containment items & Miscellaneous PVC items along with delivery. PVC Containment items include PVC bags such as posting bags and blister bags. These bags are used on the handling of, and safe interim storage of, radioactive and toxic materials of a hazardous nature and must therefore be of suitable quality of mechanical strength, leak tightness, material reproducibility and general finish. These items form the primary containment barrier layer between radioactive alpha material and the operator during glove box operations and maintenance. PVC items are used in production operations, retrievals and post operational clean-out plus long- and short-term storage of alpha bearing product and waste. PVC tents are also required under this contract. These are temporary containment features erected around the work area to prevent contamination. Invasive maintenance and repair or decommissioning operations generally result in disturbing contamination as part of the process, but these activities cannot go ahead without this containment. All PVC items produced must meet the relevant Sellafield Ltd Goods specification or be supported with the relevant concessions or manufacturing permits The items will be ordered as required as call off orders and there is no guarantee of volumes. There is a requirement for inspection across the goods specifications Full specifications and procurement documents for this tender are available to interested parties who register on Atamis project C10247, details on how to do this are contained within this notice. A preliminary Market Engagement (UK2) Notice has not been issued ahead of this Tender (UK4) Notice, this is because a Prior Information Notice (PIN) was issued under PCR2015 in January 2025 to inform the market of a Market Engagement Event to be held in February 2025, a link to this notice is contained in the following link https://www.find-tender.service.gov.uk/Notice/000995-2025 The event was run in Feb 2025. A copy of the presentation slides delivered during this market engagement event along with the summary Questions & Answer documents have been uploaded into Atamis Project C10247, under the Documents Folder 0.

The reasons for not splitting this requirement into several smaller lots are; * This option best enables the delivery of all CSF's. * The environmental impact will be less through having a single supplier as opposed to a multi-supplier contract i.e., reduction in deliveries and CO2 emissions. * Demand management will be better controlled through placing all orders through a single supplier, reducing the administration burden. * Market Engagement activities have confirmed that a single Lot with a sole supplier is a more attractive package to the market than multiple lots, enabling greater competition"
