This procurement falls within the services category, specifically related to radioactive materials and mechanical engineering. The tender period concludes on 4th November 2019, and the contract is expected to commence on 15th November 2019, lasting until 27th March 2020. The services required will be delivered in the South East region of the United Kingdom. This tender presents significant opportunities for businesses specialising in engineering services, particularly those with expertise in heat exchange units and innovative material design. Small and medium-sized enterprises (SMEs) are encouraged to participate, especially those capable of developing preliminary concept designs for high heat flux heat pipes suitable for use in sophisticated fusion reactor applications. Engaging in this project could facilitate collaboration across industries, ultimately contributing to advancements in nuclear technology and services. ## Notice Managing the heat exhaust from a fusion reactor is one of the most pressing challenges facing those seeking to realise a commercial power plant design For spherical tokamak designs such as STEP, the compact nature of the device potentially increases the heat fluxes on the plasma-facing components and restricts the space for incorporating cooling when compared to conventional larger aspect-ratio tokamaks such as ITER or EU-DEMO. A fusion reactor heat exhaust is handled via a divertor, which needs to handle large heat fluxes (>10 MW.m-2) especially in the divertor target 2Heat pipes have been proposed as potential technology for fusion high heat flux components since at least 1972. Liquid metal filled heat pipes have been tested under fusion relevant heat fluxes as recently as 2018. Despite this, there remain significant outstanding questions before they can be considered as a feasible solution for the fusion heat exhaust problem The STEP Work Package 5 (Resilient Nuclear Components) wishes to harness industrial expertise in heat pipe design outside the fusion community and to identify whether this expertise can be applied to developing an innovative heat pipe concept design for the STEP divertor target. This design challenge is ultimately concerned with the feasibility of implementation for a heat pipe high heat flux handling solution within the divertor region of a fusion reactor. The UKAEA is seeking the assessment of innovative preliminary concept designs of a high heat flux heat pipe suitable for use as a STEP divertor target. The total duration of the activities of this initial contract shall not exceed 12 weeks and must be completed by March 2020. ## Key Details | Field | Value | | --- | --- | | Publication source | Contracts Finder | | Latest notice | https://www.contractsfinder.service.gov.uk/Notice/8d85eca9-fb80-467b-976c-e7f8ecc05444 | | Notice type | Tender Notice | | Procurement type | Standard | | Procurement category | Services | | Procurement method | Open | | Procurement method details | Open procedure | | Tender suitability | SME | | Awardee scale | Not specified | | All stages | Tender | ## Dates | Field | Value | | --- | --- | | Publication date | 7 Oct 2019 | | Submission deadline | 4 Nov 2019 | | Future notice date | Not specified | | Award date | Not specified | | Contract period | 15 Nov 2019 - 27 Mar 2020 | | Recurrence | Not specified | ## Values | Field | Value | | --- | --- | | Tender value | Not specified | | Lots value | Not specified | | Awards value | Not specified | | Contracts value | Not specified | ## Status | Field | Value | | --- | --- | | Tender status | Active | | Lots status | Not specified | | Awards status | Not specified | | Contracts status | Not specified | ## Buyer | Field | Value | | --- | --- | | Main buyer | UNITED KINGDOM ATOMIC ENERGY AUTHORITY | | Locality | ABINGDON | | Post town | Oxford | | Postcode | OX14 3DB | | Country | England | | ITL 1 | TLJ South East (England) | | ITL 2 | TLJ1 Berkshire, Buckinghamshire and Oxfordshire | | ITL 3 | TLJ14 Oxfordshire CC | | Local authority | South Oxfordshire | | Electoral ward | Sandford & the Wittenhams | | Westminster constituency | Didcot and Wantage | | Delivery location | TLJ South East (England) | ## CPV Codes ### Divisions - 09 - Petroleum products, fuel, electricity and other sources of energy - 38 - Laboratory, optical and precision equipments (excl. glasses) - 42 - Industrial machinery - 71 - Architectural, construction, engineering and inspection services - 73 - Research and development services and related consultancy services ### Codes - 09343000 - Radioactive materials - 38970000 - Research, testing and scientific technical simulator - 42511100 - Heat-exchange units - 71241000 - Feasibility study, advisory service, analysis - 71333000 - Mechanical engineering services - 71335000 - Engineering studies - 71336000 - Engineering support services - 71337000 - Corrosion engineering services - 71356200 - Technical assistance services - 73120000 - Experimental development services - 73220000 - Development consultancy services - 73300000 - Design and execution of research and development ## Release History - 7 Oct 2019 at 11:01 - Tender - Tender Notice - https://www.contractsfinder.service.gov.uk/Notice/8d85eca9-fb80-467b-976c-e7f8ecc05444 ## Documents - https://www.contractsfinder.service.gov.uk/Notice/8d85eca9-fb80-467b-976c-e7f8ecc05444 7th October 2019 - Opportunity notice on Contracts Finder - https://uk.eu-supply.com/app/rfq/rwlentrance_s.asp?PID=30408&B=UK Additional data - https://uk.eu-supply.com/ctm/Company/CompanyInformation/Index/72814 User / Company ## Notice URLs - http://www.gov.uk/government/organisations/uk-atomic-energy-authority ## Provenance This Markdown file is an alternate public rendering of the D3 Tenders contract record.
