UK2 - Preliminary Market Engagement Notice
Summary of the contracting process

The Nuclear Decommissioning Authority is buying specialist radioactive-source services for the Home Office-led programme to remove and safely dispose of Caesium-137 high-activity sealed sources from medical and research irradiators. The work covers collection, dismantling, transport, storage and processing of irradiator units, removal of the sources, and packaging them for return to Sellafield’s Miscellaneous Beta Gamma Waste Store. The initial scope covers six irradiator units containing 12 sources, with an option to include three further units and six more sources. The units are Gammacell 3000 and IBL 437 models. Work may take place in the UK or abroad, but the sources are to be returned to Sellafield. The service is part of a voluntary scheme for source owners, supported by grants to replace sources with safer technologies.

The procurement is complete and Eckert and Ziegler was selected; the award is recorded as pending, while the resulting contract is active and was signed on 22 September 2025. The award date is 1 September 2025. The contract runs from 9 October 2026 to 24 September 2028, with an option to extend by one year with Authority approval. The award value is £4.5 million excluding VAT (£5.4 million including VAT). The contract recorded to date is valued at £110,873 excluding VAT (£133,047.60 including VAT). There was one lot and the open procedure attracted two valid bids. The award assessment weighted price at 25%; the remaining 75% covered technical delivery, experience and approvals, mobilisation, project organisation and social value. National security considerations may exclude suppliers whose proposals pose a risk.

This requirement shows the specialist capability the Nuclear Decommissioning Authority values for radioactive-source work: safe handling, storage, processing and transport of Caesium-137 sources and irradiator units, supported by suitable facilities, equipment and transport arrangements. Credible suppliers need the necessary consents and approvals for radioactive-material handling, storage, transport and any import or export, alongside robust safety, security, quality-management and emergency-response arrangements. The Authority also assessed detailed delivery planning, including interim storage capacity, contingency arrangements, workload capacity, health and safety plans, and the ability to interface with the 1648C transport package and disposable liner. Relevant staff experience, a clearly defined delivery team, evidence of previous performance and learning from experience matter. Suppliers should also be able to demonstrate reliable project controls and environmental measures, particularly for transport and waste reduction. National security suitability is essential.

Notice Information

Notice Title

The provisions for services to collect, transport, store and process existing High Activity Sealed Radioactive Sources (SRS) using a pre-determined disposal route.

Notice Description

The Home Office have established a programme for the replacement and disposal of Caesium-137 High Activity Sealed Sources (HASS), used in the medical and research industries, as part of a strategy to reduce the likelihood of a terrorist using high risk radiological materials in the UK. The Nuclear Decommissioning Authority (NDA) has been instructed by the Department of Energy Security & Net-Zero (DESNZ) to support the Home Office-led initiative by providing support and expertise knowledge for the collection of the HASS and managing the HASS through a suitable waste management route. The Miscellaneous Beta Gamma Waste Store (MBGWS) at Sellafield is the current waste management route for sealed sources in the UK. The programme is voluntary, meaning owners of Cs-137 sources (End-Users) within scope can apply to participate in the scheme to dispose of their sources and receive a grant for replacing with safer technologies. The programme will be delivered in phases as End-Users make their sources available for disposal. The NDA, with their trusted partner Nuclear Transport Solutions (NTS), is leading on the procurement and delivery of the first phase of this programme. This first phase of the programme will act as a pathfinder and lessons learned will be fundamental for the future success of the programme. The NDA are looking for a supplier, or consortium of suppliers, to deliver the first phase of this programme. The high-level scope of this procurement includes: * Number of Irradiator Units - 6 with the option to add a further 3 Irradiator Units * Number of Cs-137 sources - 12 sources in the 6 original Irradiator Units with 2 sources per Irradiator Unit, potential for a further 6 sources in the optional 3 Irradiator Units * Geographical area - United Kingdom * Models of Irradiator Units - Gammacell (r) 3000 and IBL 437 * Supplier to collect, transport, store and process the Irradiator Unit(s), ), in the UK or abroad, to remove the Cs-137 sources. * Pack the Cs-137 sources into the disposable liner and 1648C transport package for return to Sellafield MBGWS. The 1648C transport package is an NDA Group asset that is currently in the process of being licenced as a Type B(M) transport package, led by Nuclear Transport Solutions (NTS). The 1648C is widely and regularly received and managed at MBGWS at Sellafield. The proposed scope is likely to be broadly split into two delivery phases: Phase 1 * The Supplier is to complete all pre-collection activities to prepare the Irradiator Unit(s) for collection from the End-User premises including, but not limited to, obtaining all required permits and licences, coordinating on logistics and schedules and putting in place all health and safety requirements etc. * The Supplier is to dismantle the Irradiator Unit(s) and package the Irradiator Unit(s) for transport to the Supplier premises (in the UK or abroad) ensuring it has the required consents and permits to transport . * The Supplier will ensure they have all required permits and capacity to store the sources for up to 36 months on the Supplier premises in either the Irradiator Units or a suitable liner. * The Supplier will process the Irradiator Unit(s) to remove the Cs-137 sources and place into the appropriate liner. * Additionally, the Supplier premises will have the capability, or agree to develop the capability, to handle and interface with the 1648C and its accompanying liner once it has been licenced enabling the sources to be packed into the disposable liner for return to Sellafield. * The Supplier will pack the sources into the disposable liner and the 1648C transport package, when available. After completion of Phase 1, the Authority will have the option to exercise a break clause within the proposed contract should the Supplier not be required for return of the sources. In the event that the Supplier is not required for return of the sources, the Supplier commits to support the Authority in preparing the sources for return via an alternative route to be determined. Phase 2 * The Supplier will collect the 1648C transport packages and disposable liners from the UK and transport to the Supplier premises ready for return of the sources. * The Supplier will then load the sources into the disposable liner and subsequently the 1648C transport packages, onto the universal transport frame (UTF), and transport the sources back to the UK, directly to Sellafield. Please be advised that participation in this procurement process is subject to national security considerations. Suppliers may be excluded if their proposal is deemed to pose a risk to national security.
