UK Public Sector Contracts & Tenders

UKAEA aims to procure a molten salt flow loop with the ability to heat, pump and remove samples of test material and molten fluoride salt. The purchase of commercially developed equipment for this application is intended for rapid development of in-house operational skills and experience, as well as generation of scientific data on materials compatibility and salt chemistry.

The Authority wishes to commission an organisation to deliver a work package to provide a repurposed and refurbished 400/36kV private network that is sufficient for current and future UKAEA operations and private Fusion facilities after the closure of the JET experiment at the Culham Science Centre.

CALLIOPE is a specific work package related to preparation and tritium accountancy of samples for the THALIA project. As a part of CALLIOPE, it is required to develop and verify a new tritium accountancy method in FLiBe in addition to already established methods. This will assist in comparison of different methods against each other and validation of tritium accountancy for future processes.

UKAEA is seeking a 3-year contract (with the option to extend for 1 year) with a Consultant to conduct a series of audits agreed with the UKAEA Audit & Risk Assurance Committee annually.

Provision of a calorimeter to measure the tritium inventory for the H3AT Facility.

The UK Atomic Energy Authority (UKAEA) is regularly required to provide and install new installations, refurbish existing buildings, facilities and operational property from which it carries out its operations and provides services to tenants located on its site. UKAEA is looking to establish a framework with a number of suppliers to support in this aspect, complementing existing arrangements in support of the above. If you are a Supplier who is interested in tendering for this requirement please submit a message via the uk.eu-supply.com tendering portal under Quote ID 100109193.

Industry Simulation Software for UKAEA. Please see PME documents for more information.

UKAEA has set up the Technology Transfer Hub (TTH) to identify opportunities for technology transfer into the wider fusion market and other sectors, and to drive the commercialisation of fusion-related technologies and knowhow for the benefit of the UK economy. This Preliminary Market Engagement (PME) is to gather information to frame an invitation to tender to set up an Open Framework catering to the TTH, including expertise to help facilitate knowledge and technology transfer, IP commercialisation and the development and validation of novel technologies.

This Procurement Project is to create a Framework for the delivery of future projects relating to the Fusion Futures programme. This Framework is designed for the Fusion Futures Industry Capability programme but not limited to it.

UKAEA wishes to engage with cryogenic contractors, Small to Medium Enterprises (SME), designers and manufacturers for the supply of a liquid nitrogen (LN2) storage and delivery system for the Tritium Plant located in the new Hydrogen 3 Advanced Technology (H3AT) Facility at the Culham Campus.

A single lot consisting of the following items: Mechanical load frame for static, quasi static and cyclic mechanical loading. The load frame will have the mechanical infrastructure, control systems, and software capable of supporting numerous standard mechanical tests, specifically: tensile, compression, and low cycle fatigue. Optionally, the system may support testing for, ratchetting, creep, creep fatigue, crack growth in fatigue, and crack growth in creep. The load frame should include one or more load cells with a maximum capacity of 100 kN (unless justified otherwise), fixtures and gripping solutions for standard geometry specimens of the material families of interest at ultra-high temperatures: refractory metallic alloys, ceramics, and ceramic-matrix composites. The load string must be capable of operating up to the required temperature for at least one test, with the understanding that fixtures are consumable when operating at these temperatures. The load frame(s) should have appropriate test control systems (e.g. to control for strain on the sample at temperature) and sufficient working space to permit the insertion of vacuum and heating systems. A vacuum system compatible with mechanical testing at ultra-high temperature. There must be ports for test control, optical ports for the data-rich diagnostics and their calibration and additional ports to allow future flexibility in diagnostics. A gas introduction system to allow alternative atmosphere testing. A heating system to allow sample test temperatures up to at least 2,000 °C with a preference for an ability to test at temperatures of up to 2,500 °C for the material families of interest. The heating system must not limit the line of sight for the data-rich diagnostics. An appropriate cooling system to protect the load cell and fixtures, where required. Support with installation, commissioning, and training on the use of the above.

JET Decommissioning and Repurposing Waste Data System. 3.1. The United Kingdom Atomic Energy Authority (UKAEA) are seeking a new Inventory System to track radioactive materials generated from site activities, especially in reference to radioactive materials produced from the decommissioning of the JET tokamak system. The expected complexity and amount of material arising from this decommissioning, as well as longevity concerns, have prompted aspirations to move away from the current Microsoft Access based waste inventory system. Hence a replacement system is required which provides increased capability and greater security in application support. The Preliminary Market engagement is seeking general information around experience, the platform, hosting, maintenance, pricing models and indicative costs.

The UK Atomic Energy Authority has a requirement for the Design, Manufacture, Delivery, Installation and Commissioning of Three Large Megawatt Power Supplies to power and control the current within the Pc, P4 & P5 Magnet Coils on the MAST-U Tokamak Fusion Experiment. Further details of the requirement are available on the link in this notice.

The Fusion Opportunities in Skills, Training, Education and Research (FOSTER) programme is an ambitious national fusion skills programme delivered by UKAEA on behalf of the UK fusion sector. FOSTER’s mission is to train over 2000 people by 2030, ready to take roles within the fusion industry.

The main HV Pulsed Power supply to the Culham site is via a dedicated overhead line fed directly from the National Grid at 400kV and transformed down by three 90 MVA 400/36kV super grid transformers (SGT’s) normally operated in parallel. Original installation of the Super-Grid Transformers was installed over 40 years ago and original spares are practically non-existent. They are an aging asset, with cooling becoming more critical with weather and with the potential of new increased loading due to new customers on site. Therefore, replacement of the 5 remaining Blast Air Coolers is important to extend the lifespan of the equipment. The Blast Air Coolers provide cooling to the oil inside the transformer tank. There are 4 Blast Air Coolers located on each SGT, for a total of 12 units. In 2016, the first phase of this replacement was carried out, replacing 7 of the original units. This project is to replace the remaining 5 original units.
