This initiative is in the planning stage, with a planned future notice date of 30 June 2022. The procurement involves the design of a fluidised bed chemical vapour deposition system intended for use in a controlled environment at the Preston site in the UK, with a budget of £1,500,000. Interested parties should prepare for an upcoming Invitation to Tender for the design, build, and installation of the equipment that meets specific operational requirements. This tender presents a significant opportunity for businesses engaged in advanced manufacturing and technical design, particularly those specialising in nuclear equipment and chemical processing. Companies with experience in constructing fluidised bed systems, handling radioactive materials, or working on nuclear licensed sites will be particularly well-suited to compete. The focus on innovative reactor fuel technologies aligns with the UK’s environmental goals, offering potential for businesses to contribute to and benefit from the transition to net zero carbon emissions by 2050. ## Notice NNL are seeking to place a contract for the design of a fluidised bed chemical vapour deposition system. The equipment should have a coating chamber diameter of around 150mm and be capable of coating 1-2 kg of 0.5mm diameter kernels of uranium dioxide (UO2) in a single batch. Each coating will need to be deposited from different precursors sequentially while at its operating temperature, ranging from 1200-1600degC. The expected precursors for the different coating layers are acetylene, acetylene/propylene mixtures and methyltrichlorosilane diluted in hydrogen. An argon carrier gas is also required for fluidisation. Due consideration will need to be given to the scrubbing of exhaust gases and to the safe operation of the equipment using these reactive precursors on a nuclear licensed site. ### Lot Information Lot 1 NNL are interested in developing capabilities for the manufacture of fuels for the next generation of advanced modular reactors to contribute to the UK's target of reaching net zero carbon emissions by 2050. A promising candidate reactor technology are high temperature gas cooled reactors, which have high efficiencies, passive safety features and potential for co-generation of hydrogen. The fuels of these reactors are termed coated particle fuels and consist of spherical particles (approx. 0.5 mm diameter) coated in successive layers of porous carbon, pyrolytic carbon and silicon carbide. The coating process is traditionally carried out using fluidised bed chemical vapour deposition equipment, in which the particles are suspended within a fluidised bed while deposition of coating layers occurs by reaction of suitable precursors.

An argon carrier gas is also required for fluidisation. Due consideration will need to be given to the scrubbing of exhaust gases and to the safe operation of the equipment using these reactive precursors on a nuclear licensed site. The system will need to conform to standards required for operation within a controlled area, with due consideration for handling of radioactive materials while loading and unloading the coater, contamination control and ease of maintenance. To support the drafting of a future Invitation to Tender for the procurement of design, build and installation services for a fluidised bed chemical vapour deposition coater, NNL request interested parties to respond with a summary of their current, existing capabilities. Respondents should also indicate if they would have the capability to build and deliver a system to the proposed design together with any prior experience of working on or supply equipment/services to nuclear licensed sites. ## Key Details | Field | Value | | --- | --- | | Publication source | Find A Tender Service | | Latest notice | https://www.find-tender.service.gov.uk/Notice/000796-2022 | | Notice type | Planning Notice | | Procurement type | Standard | | Procurement category | Goods | | Procurement method | Not Specified | | Procurement method details | Not specified | | Tender suitability | Not specified | | Awardee scale | Not specified | | All stages | Planning | ## Dates | Field | Value | | --- | --- | | Publication date | 11 Jan 2022 | | Submission deadline | Not specified | | Future notice date | 29 Jun 2022 | | Award date | Not specified | | Contract period | Not specified | | Recurrence | Not specified | ## Values | Field | Value | | --- | --- | | Tender value | £1,500,000 | | Lots value | Not specified | | Awards value | Not specified | | Contracts value | Not specified | ## Status | Field | Value | | --- | --- | | Tender status | Planned | | Lots status | Planned | | Awards status | Not specified | | Contracts status | Not specified | ## Buyer | Field | Value | | --- | --- | | Main buyer | CTM PORTAL FOR THE NDA SHARED SERVICES ALLIANCE | | Locality | SEASCALE | | Post town | Carlisle | | Postcode | CA20 1PG | | Country | England | | ITL 1 | TLD North West (England) | | ITL 2 | TLD1 Cumbria | | ITL 3 | TLD13 Cumberland | | Local authority | Cumberland | | Electoral ward | Gosforth | | Westminster constituency | Whitehaven and Workington | | Delivery location | TLD4 Lancashire, TLD61 Warrington | ## CPV Codes ### Divisions - 44 - Construction structures and materials; auxiliary products to construction (except electric apparatus) ### Codes - 44000000 - Construction structures and materials; auxiliary products to construction (except electric apparatus) ## Release History - 11 Jan 2022 at 17:12 - Planning - Planning Notice - https://www.find-tender.service.gov.uk/Notice/000796-2022 ## Notice URLs - https://sharedsystems.eu-supply.com/app/rfq/rwlentrance_s.asp?PID=15399&B=SELLAFIELD - https://sharedsystems.eu-supply.com/ctm/Company/CompanyInformation/Index/3510 - https://www.gov.uk/government/case-studies/shared-services-alliance-ssa-for-nuclear-decommissioning-estate ## Provenance This Markdown file is an alternate public rendering of the D3 Tenders contract record.
