UK Public Sector Contracts & Tenders

Industry provides simulation software and methods covering a wide range of capability, deployed across all engineering sectors, much of which will be invaluable for use in the design and operation of fusion reactors in a Fusion energy industry. However, the extent to which existing capability is sufficient to facilitate design and realisation of commercial fusion powerplants is not clearly defined. Industry Simulation Software for Fusion is a multi-year rolling project aiming to define Fusion relevant analysis and simulation case studies and use them as a formal basis to engage industry for evaluation of their simulation software capability and identify development needs. The case studies to be submitted will span the full range of domains relevant to realisation of fusion as an energy source, with a mixture of single and multi-domain scenarios and involving use of a variety of methods and techniques. A total of four case study areas are covered in this procurement exercise.

An activity-based pricing model will be used, with separate schedules for labour and equipment hire. Mandatory site visits will be required for all bidders. The contract value is approximately £200,000 with a target start date of August 2025.

This tender is to find supplier for Monitoring of facility stack and workplace tritium discharges to comply with site permits

Fusion offers potential future energy abundance yet is at the same time highly challenging. In the context of a fusion future full of opportunity, but also complexity, UKAEA wishes to learn more about potential future energy landscapes and ecosystems. In such energy ecosystems, fusion might enter in various ways, perhaps replacing technologies existing at the time (e.g. due to obsolescence/end of life), perhaps augmenting other technologies to address the increasing demand or aiming at affordable solutions for specific supply needs and characteristics not readily met by other technologies. In particular, uses of fusion might expand beyond grid electricity. UKAEA is interested to see what potential characteristics of fusion plants might help or hinder fusion deployment, as this can inform UKAEA’s future strategy.

The Contractor's scope shall include the design, manufacture, delivery, and functional demonstration (including all required testing, verification, and documentation) for two (2) off SPOT Arm Haptic Control System hardware.

Design, Supply, and Installation of a Liquid Nitrogen Storage and Distribution System for the H3AT Facility at UKAEA Culham Campus

IMPORTANT NOTICE – THIS IS NOT A PROCUREMENT TENDER Please note that this does not constitute a procurement tender as UKAEA are selling assets rather than procuring goods or services. This process does not fall under the requirements of the Procurement Act 2023 (PA23). Any references to tendering are for the purpose of ensuring a transparent and competitive sale process and are not subject to public procurement rules.

The United Kingdom Atomic Energy Authority (UKAEA) are undertaking the JET Decommissioning and Repurposing (JDR) programme, a multi-year programme in which the Joint European Torus (JET) fusion system will be decommissioned and key infrastructure is repurposed for further use. The JET tokamak, and the associated supporting systems, power supplies, diagnostic systems, and buildings represent a significant infrastructure for the JDR programme to handle. Due to the operation of a fusion system some materials require specialist management as either radioactive or chemically hazardous material. A key criteria for managing these materials is the storage of relevant information and the tracking of material. UKAEA are seeking a digital solution to aid with this information storage and tracking in the form of a material inventory system. Since the materials concerned will mostly be wastes, this is hence referred to as a ‘Waste Data System’ or ‘Waste Inventory System’ as is commonplace within the nuclear sector. UKAEA is a public body tasked with progressing fusion research and is hence free from excessive security considerations which often accompany sensitive nuclear materials associated with nuclear fission. UKAEA is seeking a design, build, host, and support contract for this system. It is expected that the design / build phase of the project is expected to consist of an initial period (~12 months), followed by a prolonged hosting and support functionality for an extended period. It is expected that this will be a combined period of up to 5 years. Please note the submission deadline for Stage 1 is 18/07/2025.

This is a Contracts for Innovation (previously SBRI) competition funded by the UK Atomic Energy Authority. The aim of the competition is to develop solutions to fusion energy challenges in two key priority areas. The competition has 1 theme: Novel shielding materials and technologies for fusion. We expect to fund a number of projects. Each project should be delivered by April 2026. Each project can range in size up to total costs of £250,000, inclusive of VAT. Please refer to attachments for the full competition guidance.

IT Cabling - UKAEA Culham Site. Constant office refurbishments and new installation requests involve installing new cables and removing existing obsolete cabling alongside with the existing data and power infrastructures. Any new complex builds e.g. a new building requires end-to-end involvement from a data contractor and includes not only the installation and commissioning of the LAN services, but also recommendations, advise and design. These require a specialised team that will understand potential challenges and hazards and follow health and safety, as well as building, regulations.
