Alternative skip handler for nuclear storage ponds challenge.pdf

Figure 1. FGMSP Pond.jpg

CHALLENGE AIMSSellafield Ltd is seeking solutions that can effectively interface with skips, move and reposition them within the ponds, and allow recovery of those skips into safer storage.The main aim is to allow movement of skips within the FGMSP without reliance on the SHM (i.e. so skips can still be moved when the SHM is in outage). Any solution must be able to work under the pond water conditions and accurately move the skips from stacks to the export cell and bay bogies around the pond.Additionally, the solution should be able to deploy with the sludge retrieval tools to enable the removal of radioactive sludge from the ponds.Within the stacks, it is acknowledged that some solutions may not be able to access skips adjacent to the pond walls or in the corners, and, whilst this would be preferrable, Sellafield Ltd still would be open to solutions that can only manage a limited number of skips.Whilst the FGMSP is the main focus, solutions that can be applied to the PFSP would also be desirable.The Legacy Ponds Programme is currently considering short-term solutions to enable skip movements for export from FGMSP due to the SHM repair outage, with the focus on short time to implementation. This Game Changers challenge is intended to address the longer-term need for performance and reliability as well as the ability to undertake all functions required of the current SHM.As Sellafield Ltd’s legacy ponds retrievals programme is currently ongoing, solutions that can be implemented within a 1–2 year timeframe would be advantageous. Full solutions or partial solutions that can enable a suite of different technologies in a retrievals toolkit are welcomed.

ADDITIONAL INFORMATION FOR THIS CHALLENGEWhat are the safety case requirements for the lift process, e.g. redundant load paths or seismic assessment?The current safety case has been assessed against the current system without wider consideration; hence new solutions would require an update to the safety case assessment and possibly subject to HAZOP review. However, this should not rule out innovation of new ideas. There may be some elements that are covered by the existing safety case, e.g. dropped loads for SHM will have been assessed based on skip remaining underwater.Ultimately, solutions will require more general balance of ALARP arguments based various parameters, e.g. dose, failure and recovery, space constraints, performance and reliability. For example, in comparison to a small floating platform, a 600t crawler crane lifting skips out of the pond would need a fairly compelling argument to justify.Is chemical analysis/composition of pond water available for material selection?The pond water is caustic dosed to pH 11.6 and contains various particulates from spent Magnox fuel corrosion. Various radiological species and competing ions are monitored, such as total beta, total alpha, Cs-137, Sr-90, Mg (total and soluble), Na, K, Ca. More detailed chemical analysis can be made available to successful applicants.If we're successful in the second phase and provide a viable solution, what's the estimated potential value?In terms of the value of an alternative to the SHM, we generally assess the number of years off programme as a measure of reduction in hazard and risk. In terms of monetary value, an order of magnitude estimate is available on the gov website (<a href="https://www.gov.uk/government/case-studies/quality-and-continuous-improvement-first-generation-magnox-storage-pond-fgmsp#:~:text=The%20information%20on%20how%20much,timescales%20extending%20into%20the%20future." rel="noopener noreferrer" target="_blank">Quality and Continuous Improvement - First Generation Magnox Storage Pond (FGMSP) - Case study - GOV.UK</a>) outlining "each year the project is extended an additional sum of approximately £60 million would be needed".

Alternative skip handler for nuclear storage ponds

Sellafield Ltd is seeking an alternative to the Skip Handling Machine (SHM) used in the First Generation Magnox Storage Pond (FGMSP). The FGMSP is an ageing and degrading facility and a high Hazard and Risk Reduction priority. Reliance on a single crane limits throughput, particularly during planned maintenance or unplanned outages. The challenge is to identify a solution that can safely operate underwater to move and position skips, work alongside or independently of the SHM, and potentially deploy sludge retrieval tools. Applicability to the Pile Fuel Storage Pond (PFSP) and other sites would be beneficial.An alternative skip handling solution would increase operational resilience by allowing skip movements and exports to continue when the SHM is unavailable, while also accelerating exports when used in parallel.

Sellafield Ltd seeks an alternative skip handling system for ageing nuclear storage ponds to maintain and accelerate skip movements and exports, supporting Hazard and Risk Reduction when the existing Skip Handling Machine is unavailable.

Immobilising spring hangers challenge.pdf

Spring hangers web.jpg

CHALLENGE AIMSNRS is seeking solutions that will support and immobilise structures that are currently supported by spring hangers.During decommissioning, NRS will need to remove all spring hangers, including those providing essential structural support. During this removal process, it is essential to provide alternative support for the structures that are currently suspended from spring hangers to maintain their structural integrity. These structures will need to remain in situ for a number of years whilst decommissioning operations are undertaken.Ideally, any solutions to this challenge would be applied remotely, although this is not essential. Where solutions cannot be applied remotely, the use of specialist rope access or other means that avoid the need for scaffolding structures for access are preferred.Ideally, solutions would be deployed in tandem with the protection methods described in the Current Practice section. Where this is not the case, solutions should also provide a means to prevent the ejection of spring hanger components in the event of tie-rod failure or spring-shatter/collapse.NRS has an immediate focus on the hardest-to-reach assemblies at Hinckley Point A, but that particular scenario is not the limit of application for successful solutions to this challenge.

Immobilising spring hanger assemblies for safe decommissioning

Nuclear Restoration Services Ltd (NRS) is decommissioning former Magnox nuclear power stations, where ducting in pressurised circuits was supported by spring hangers to absorb vibration and thermal movement. Larger, pre-compressed versions – constant load spring hangers – remain in use across sites, with around 1,000 still supporting essential ducting. These contain significant stored energy, posing a risk of high-speed projectile failure if released.During decommissioning, NRS must safely remove all spring hangers while maintaining alternative structural support to prevent ducting movement and ensure stability of suspended systems throughout the lengthy decommissioning process.

Moving waste materials within storage silo compartments

A significant challenge in the decommissioning of Sellafield site is emptying radioactive waste from the Magnox Swarf Storage Silos (MSSS). To date, the removal of waste material from MSSS compartments has been performed by the Silo Emptying Plant (SEP), which is only able to retrieve waste in the central area of a compartment resulting in the formation of a crater.Sellafield Ltd is seeking a new approach to managing the removal of this waste, which can either avoid craters being created or better manage them if they are created. Additionally, an accurate method to measure the waste bed profile could significantly improve the efficiency and risk management of waste removal operations.

Characterisation of fuel derived materials.pdf

SP_05 web.png

CHALLENGE AIMSSellafield Ltd is seeking solutions that can effectively identify and quantify fuel derived materials including:<ul><li>Magnox </li><li>Magnesium hydroxide </li><li>Uranium </li><li>Uranium corrosion products, which are predominantly uranium oxide </li></ul>These materials may be stored under dry, damp or underwater conditions, depending on the facility. It is understood that a single solution may not be viable to conduct characterisations under all of these conditions. Partial solutions that can characterise materials in any of the storage scenarios described are welcomed. To enable characterisation within the FGMSP, a solution must be capable of being mounted on a Remotely Operated Vehicle (ROV) or manipulator arm, to reach fuel derived waste that is stored under water.Wider benefits could be realised if a proposed solution can:<ul><li>Distinguish other materials such as steel and aluminium.</li><li>Perform characterisation at various processing stages to ensure materials are managed appropriately and allow for informed decision-making based on accurate data.</li><li>Characterise the compositions of materials in the MSSS compartments in-situ, prior to retrieval. This would allow for more streamlined retrieval operations and provide feedback to the current material transition models.</li><li>Identify small pieces of waste, typically between 8mm and 100mm in size, which would improve waste management and processing outcomes.</li></ul>As Sellafield Ltd’s legacy waste retrievals programme is currently ongoing, solutions that can be implemented within a 1-2 year timeframe would be advantageous.Whilst deployability of characterisation methods is a critical consideration, finding a solution capable of conducting the required characterisation of these fuel derived materials is the initial challenge.

Due to the presence of debris, welds and protrusions, this is likely to be narrower than 25mm at points throughout, with an expected minimum of 20mm.

Internal inspection of long and narrow pipework

Routine visual inspection of existing assets across the Sellafield site is important to understand their condition, identify any defects, and manage the risk of failure. Internal inspection of narrow pipework can be particularly challenging due to bends, corrosion debris, lack of lighting, and the length of pipes.One example of such pipework is an overflow drain line that services the Sellafield Sealines. This drain line must be inspected every 2 years to ensure there is no damage or blockage. A solution is required that can provide live HD colour video of over 40m of pipework with an internal diameter of 20mm, navigating grit/sand, protruding circumferential welds and multiple bends.

Sellafield Ltd is seeking a technology capable of conducting internal visual inspection of long, narrow, convoluted pipework, providing live HD colour video to assess condition, identify any defects, and manage the risk of failure.

In-situ real-time characterisation and measurement of materials for effective nuclear waste management

Waste on the Sellafield site must be classified and any hazardous properties identified before handling and disposal. Conducting measurements in situ enables faster, real-time data gathering and analysis, facilitating immediate decision-making regarding the treatment, storage, recovery or disposal of waste.With such varied waste materials at Sellafield, it is recognised that a ‘toolbox’ of different technologies may be required, preferably one that works over a wide range of environments, providing a large suite of data/analysis. Note that not all analysis requires a numerical value to be beneficial and determining an analyte to be below the relevant hazardous waste threshold may be sufficient.

Sellafield Ltd is pursuing innovative solutions to accelerate the characterisation and measurement of materials through in-field testing capabilities.

Amentum PoC pic.png

Amentum’s ThreadSafe project is showing the potential to revolutionise the way Sellafield Ltd manages Nuclear Safety Cases, improving efficiency in change management. Through a successful feasibility phase, ThreadSafe has already demonstrated its potential to automate complex information management tasks, reduce risk, and accelerate decision-making. With a 16-week Proof of Concept (PoC) now underway, the project aims to deliver a bespoke, scalable solution that provides a robust and verifiable “golden thread” across the entire safety case lifecycle.<h2>The Challenge: Making the Golden Thread Truly Golden</h2>Nuclear Safety Cases underpin every operational decision at Sellafield Ltd. They provide the evidence that hazards are controlled, operations are safe, and risks are reduced to as low as reasonably practicable (ALARP). Yet these cases are built on extensive, constantly changing documentation, a range of formats, and extensive manual cross-checking.The <a href="https://www.gamechangers.technology/challenge/Improvement_of_information_management_in_Nuclear_Safety_Cases" rel="noopener noreferrer" target="_blank">Improvement of information management in Nuclear Safety Cases&nbsp;challenge</a>, launched&nbsp;in July 2024, aimed to strengthen the accuracy and visibility of the Safety Case “golden thread,” reduce the time and cost of developing and maintaining cases, and introduce automation to free specialists from manual checking. It also sought to improve change control – ensuring a single update triggers all necessary revisions – and to deliver a solution compatible with existing Safety Cases and varied legacy formats.For Sellafield Ltd, improving Safety Case management is essential to accelerating its mission. Reducing manual effort, tightening consistency, and enabling data-driven updates all contribute directly to safer, faster and more efficient operations.<h2>The Technology: Secure, Smart, and Purpose-Built</h2>Amentum’s ThreadSafe stood out among the challenge applicants, with its proposal selected for a feasibility study. Unlike off-the-shelf systems, ThreadSafe offers a bespoke, Sellafield-directed capability built around a secure, on-premise architecture designed to operate within sensitive environments.The technology automatically identifies and maps relationships between engineering requirements, safety arguments, operational instructions, and associated documents using an ontology-driven, graph-based approach. Rather than acting as another document management tool, ThreadSafe is designed as a powerful information management system – treating information as an asset and enabling users to see contextualised links across multiple formats and repositories.<h2>Feasibility Success: Rapid Delivery and Early Impact</h2>Amentum delivered an early Minimum Viable Product within weeks – precisely the rapid turnaround the challenge owners hoped for. The working prototype showcased the core features required to demonstrate feasibility, including relationship mapping, automated insights and a functional user interface.By sitting alongside existing Sellafield systems, ThreadSafe proved it could be integrated without major disruption and could enhance, rather than replace, established processes. Feedback loops with Sellafield’s safety case professionals ensured that improvements were immediately incorporated, accelerating the tool’s maturity.<h2>Next Steps: A 16-Week PoC to Deliver a Working System</h2>Amentum is now midway through a 16-week agile PoC, focused on refining ThreadSafe into a fully functioning system tailored for Sellafield’s needs. Sellafield’s challenge owners describe the potential impact as “genuinely game-changing” – cutting time spent on checks, improving consistency, and enabling quicker, more informed decisions.As one Safety Case owner noted: “It’s been great to see the initial system developing so quickly – we can already see how it will support us in our work.”James Moore, Decommissioning Technology Oversight, Remediation, Sellafield Ltd, summarised the opportunity: “We believe ThreadSafe can provide this capability.”If successful, ThreadSafe could become a model not just for Safety Cases, but for managing complex, interlinked information across the Sellafield estate and beyond.

Amentum’s ThreadSafe project is transforming Sellafield Ltd’s Nuclear Safety Cases by automating document management, improving accuracy, traceability, and change control.

ThreadSafe – transforming the golden thread of Nuclear Safety Cases

MSSS web.jpg

A suite of innovative feasibility projects has been selected to improve solutions for one of Sellafield’s most persistent decommissioning challenges: moving waste materials within the Magnox Swarf Storage Silos (MSSS). The <a href="https://www.gamechangers.technology/challenge/Moving_waste_materials_within_storage_silo_compartments" rel="noopener noreferrer" target="_blank">challenge</a> – seeking new ways to avoid or manage crater formation and improve real-time imaging of waste beds to improve the performance of the current retrievals process – closed on 28 August, drawing a wave of fresh ideas. Five applications have been chosen for feasibility funding, with projects kicking off in mid-November.The work aims to enhance or rethink how waste is retrieved from silo compartments, enabling a flatter waste bed, safer operations, and more predictable excavation. Proposed solutions span robotic manipulators, buoyant grabbers, advanced imaging, and enhanced mechanical access systems.&nbsp;<h2>CRGI Solutions – Excavator Far-End Assist (EFEA)&nbsp;</h2>CRGI is developing a retrofit system intended to extend the reach of existing silo excavators to access difficult corners currently beyond central-point retrieval tools. The feasibility project will explore how the EFEA could improve access to residual cavities, help level waste layers, and reduce the risk of grabber entrapment, aiming to support safer and more complete waste removal.<h2>Forth Engineering (Cumbria) Ltd – Buoyancy Bag Mobile Grabber&nbsp;</h2>Forth is designing a manoeuvrable, thruster-equipped buoyancy-bag platform, incorporating a camera, spreader beam, and grabber. The feasibility study will test how the device could travel to remote areas within silos to reposition waste centrally for existing tools, potentially enabling full-area coverage and improved real-time imaging of the waste bed.&nbsp;<h2>Veolia Nuclear Solutions UK Ltd – SEP Waste Manipulator&nbsp;</h2>Veolia is exploring adaptations of its long-reach carbon-fibre manipulators for the project, to be used in waste movement, clearing, and inspection. The feasibility study will assess the potential reach of an existing manipulator and how it could be installed. This assessment will leverage VR digital-twin integration to enhance planning and operator situational awareness, while also evaluating the potential for tooling to support retrieval, cleaning, and size reduction.<h2>Brokk UK Ltd – Brokk Arm System&nbsp;</h2>Brokk is testing a concept based on its electric/hydraulic robots, designed to operate in hazardous settings. The feasibility project will examine how a standalone arm configuration could provide precise excavation and waste-handling capabilities, keeping operators at a safe distance and improving operational reliability within challenging silo environments.<h2>Taylor Kightley Engineering Co. Ltd – Underwater LIDAR &amp; Blast Centralisation&nbsp;</h2>Taylor Kightley is developing a combined approach using underwater LIDAR imaging and a water- or gas-blast system. The feasibility study will assess how these technologies could map waste surfaces accurately and actively re-centre dispersed material, supporting a level waste bed and potentially improving the predictability and efficiency of retrieval operations.&nbsp;These feasibility studies will help shape the next generation of waste-retrieval technology at Sellafield, underpinning safer, more predictable and more efficient decommissioning operations.&nbsp;

Five feasibility projects are exploring advanced robotics, imaging, and handling technologies to improve waste retrieval from Sellafield’s Magnox Swarf Storage Silos, enhancing safety, efficiency, and predictability while reducing operational risks and potential costs.

Five novel feasibility projects launched to tackle Sellafield’s silo waste challenge

Alpha web.png

The University of Bristol’s Hot Robotics long-range alpha imaging project has taken a major step forward with successful demonstrations in August and September 2025. Using ultra-sensitive cameras, the VisionAlpha camera system detected and localised alpha contamination both on-site and in a mock SNM store, proving its potential to make nuclear operations safer and more efficient.<h2>Transformational Technology for Safer Alpha Detection</h2>Alpha-emitting materials such as uranium, plutonium and americium pose long-standing challenges for nuclear operators. Traditional detectors require personnel to work very close to potential contamination, increasing exposure risk and slowing surveys.The University of Bristol’s system uses alpha-induced fluorescence, capturing the ultra-faint ultraviolet light produced when alpha particles excite nitrogen molecules in the air. Its ultra-sensitive cameras can detect this fluorescence from many metres away, allowing contamination to be identified remotely with millimetric precision. The system promises to reduce personnel dose uptake, accelerate survey operations, and lower costs – benefiting nuclear facilities, waste management, environmental monitoring, and defence applications.<h2>From Feasibility Study to Proof-of-Concept</h2>The project began with a 12-week feasibility study completed in March 2023. Following positive results, Game Changers funded a 12-month proof-of-concept (PoC) project starting in January 2024. During this time, the team also progressed through the Innovate UK ICURe programme, completing EXPLORE in January 2025 and gaining entry to ICURe EXPLOIT with business advisor/commercialisation support from FIS360’s Helen Bayram and Stuart Brown.<h2>Demonstrations Highlight Real-World Impact</h2>The first demonstration tested the camera on-site in an area of known alpha contamination. The system successfully localised contamination from safe distances, validating laboratory findings and confirming operational readiness.A second demonstration explored potential applications for stored nuclear materials. Using a mock-up Special Nuclear Materials (SNM) store, the team simulated alpha contamination on cans within storage channels. The camera accurately identified contamination at varying distances and intensities without the need to remove cans – a capability that could save millions in operational costs, reduce risk to operators, and streamline planning at facilities such as Sellafield.<iframe class="ql-video" frameborder="0" allowfullscreen="true" src="https://player.vimeo.com/video/1128829665/"></iframe>James Wilcock, SNM Strategy and Innovation at Sellafield Ltd said: “We’re extremely pleased with the success of this trial. The equipment has impressed us thoroughly and shown clear potential for future applications within Sellafield.” With Benedict Robinson, Remediation Technology &amp; Innovation at Sellafield Ltd adding: “After hard work by everyone involved, we were excited to see a positive result. We are already talking about potential applications.”<h2>Next Steps</h2>With two successful demonstrations completed, the next phase focuses on preparing the system for extended on-site deployment trials. Work will include improving robustness, refining the user interface, and integrating lessons learned from recent testing.From a speculative proposal to a proven demonstrator, the University of Bristol’s long-range alpha imaging system is now poised to transform alpha detection – making nuclear operations safer, faster, and more cost-effective across the UK nuclear sector.

The University of Bristol’s long-range alpha imaging project has taken a major step forward with successful demonstrations both on-site and in a mock SNM store, proving its potential to make nuclear operations safer and more efficient.
