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. Design of deployment methodology will be addressed at a later stage.FIND OUT MOREPlease download the challenge statement for full details of this opportunity.You can watch a webinar and Q&amp;A session with the challenge owners for more information and details of how to apply.<iframe class="ql-video" frameborder="0" allowfullscreen="true" src="https://player.vimeo.com/video/1068888289/"></iframe>The deadline for applications for this challenge is 3pm on Monday 14th April 2025.ASSESSMENT OF APPLICATIONSApplications are reviewed against set criteria by a panel of challenge owners, prospective end‐users from our partner organisations, and Game Changers project staff.

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.

Non-intrusive characterisation of legacy waste drum contents

In preparation for the long-term disposal of legacy waste on the Sellafield site in a Geological Disposal Facility&nbsp;(GDF), waste package contents must be processed into a suitable safe and passive form. To process and treat the waste in the most safe, efficient and cost-effective way, Sellafield Ltd needs to fully understand the chemical, physical, radiological and fissile nature of the waste within the legacy packages.This challenge is focused on waste packages that contain untreated and unprocessed Plutonium Contaminated Material (PCM). Key to this challenge is the ability to obtain the required characterisation without opening or disturbing the contents of the PCM drums.

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.

Lift it, shift it: An alternative approach to asbestos removal

A number of buildings and pieces of equipment due to be decommissioned at Sellafield contain asbestos. There is a high potential risk of operators inhaling asbestos fibres when dismantling asbestos-containing materials (ACM), so the building dismantling process at Sellafield is conducted under strict protocols for handling and transporting ACM.Any solution that can provide sufficient containment of ACM to allow transport of larger components for off-site disposal would reduce the extent of on-site dismantling required, reduce the risk to operators, provide significant cost savings and speed up decommissioning.

Sellafield Ltd requires a safe and cost-effective means to remove asbestos-containing materials from its site. This challenge is seeking solutions that provide encapsulation of these materials prior to their removal for decontamination and disposal.

Improvement of information management in Nuclear Safety Cases

The Nuclear Safety Case is the body of evidence that justifies and demonstrates that nuclear hazards are adequately managed, that operations are safe and that associated risks are reduced to As Low As Reasonably Practicable (ALARP). All related documents are subject to constant ongoing revision. There are no live links between these documents, which exist in a variety of formats.A solution is sought that accurately and efficiently manages the transfer of information within these Nuclear Safety Cases and associated documentation, as well as providing a verifiable audit trail for the changes it proposes.

Sellafield is a large, highly complex nuclear facility with a lot of structured data across its Nuclear Safety Cases, which require manual, resource-intensive processes to cascade changes.

CHALLENGE AIMSSellafield Ltd is looking for technology that can deploy an ultra-high pressure water jetting (UHPWJ) head or other tools into a vessel that can:<ul><li>Cover the full internal surface of the vessel including internal pipework and structures.</li><li>Operate from a nozzle to surface metal distance of 50mm to 100mm.</li></ul>The aim is to decontaminate the vessel by removing the entire internal surface layer of metal.Access into the vessel is achieved via 150mm inspection ports that pass through the 1.5m thick concrete cell wall, then through a 150mm diameter access port on the metal wall of the vessel itself.Technology is being developed to cut an access port into a vessel and then fit a removable access plug through which any technological solution could be deployed.Some vessels have open tops or engineered access ports, but many don’t and would need access to be created. Therefore, the smaller and lighter the solution the better.Aggressive chemicals can be deployed by filling the entire vessel undergoing POCO; however, this produces unacceptable volumes of effluent. The ability to spray chemicals onto the internal surfaces of the vessel would use less of the reagent and reduce the effluent challenge. Ultra-high pressure water jetting (UHPWJ) or electrochemical methods would remove the need for reagents, if the deployment challenge can be solved.FIND OUT MOREPlease download the challenge statement for full details of this opportunity.You can watch a webinar and Q&amp;A session with the challenge owners for more information and details of how to apply.<iframe class="ql-video" frameborder="0" allowfullscreen="true" src="https://player.vimeo.com/video/996576919/"></iframe>The deadline for applications for this challenge is 2pm on Wednesday 21 August 2024.ASSESSMENT OF APPLICATIONSApplications are reviewed against set criteria by a panel of challenge owners, prospective end‐users from our partner organisations, and Game Changers project staff.

Directional decontamination head deployment into large, congested, highly radioactive vessels

Post Operational Clean Out (POCO) of the Sellafield site requires the internal cleaning of large, highly radioactive vessels with complex internal configurations. Sellafield Ltd is seeking innovative solutions for deploying vessel cleaning heads and ultra-high/high-pressure water jetting or spray nozzles to apply decontaminating chemicals and foams inside these structures.The vessels' internal structures can include cooling/heating coils; fluid mixing and transfer devices; instrument dip-legs; internal vessels; and pipe support brackets. All of these internal structures require full surface decontamination. Any tool deployed to clean these internal structures would need to be able to navigate around them whilst cleaning them.

Sellafield Ltd is seeking innovative solutions that will deliver improvements over the current techniques used for deploying vessel cleaning heads into large, highly radioactive vessels with complex internal configurations.

Challenge statement - Fixatives for containment of alpha contamination in gloveboxes.pdf

CP_57 web.png

CHALLENGE AIMSSellafield Ltd would like to identify a fixative that securely fixes airborne alpha particles in place, along with an application method that can be deployed through a 150mm diameter glove port. The fixative solution must be chemically compatible with the glovebox materials, stable under ambient conditions and be as long-lasting as possible. Further details can be found in the “Functional Requirements” section of the challenge statement.Due to the risks of a breach of containment posed by ageing gloveboxes, a solution is desired as soon as practicable. As operations at the Analytical Services Laboratory at Sellafield, which contains many alpha contaminated gloveboxes, are being phased out, this further exacerbates the need for a fixative solution. Other methodologies have been trialled; however, Sellafield Ltd is looking to improve upon these.The ideal scenario would be the capability to coat a glovebox sufficiently for it to be transported without an outer box or crate. Treatment that enables an empty glovebox to act as a container for waste would be an added benefit. Due to the complex states of gloveboxes across site, and the resulting requirements on fixative technology, Sellafield Ltd understands this will be a challenge.FIND OUT MOREPlease download the challenge statement for full details of this opportunity.You can watch a webinar and Q&amp;A session with the challenge owners for more information and details of how to apply.<iframe class="ql-video" frameborder="0" allowfullscreen="true" src="https://player.vimeo.com/video/992847469/"></iframe>The deadline for applications for this challenge is 3pm on Thursday 15th August 2024.ASSESSMENT OF APPLICATIONSApplications are reviewed against set criteria by a panel of challenge owners, prospective end‐users from our partner organisations, and Game Changers project staff.

Fixatives for containment of alpha contamination in gloveboxes

There are approximately 800 gloveboxes across the Sellafield site, made up of a variety of materials such as steel, plastics and elastomers, that contain radioactive material including alpha particles. Due to the advanced age of many of the gloveboxes, they may fail within the next few years, leading to a breach of containment.Sellafield Ltd would like to explore options for effective, strong and durable fixatives that would provide containment of alpha contaminated material within gloveboxes selected for decommissioning, preventing the radioactive contamination from becoming airborne during preparation and transfer of the gloveboxes for processing.

Challenge statement - Non-invasive imaging of in-ground structures.pdf

Full Image Silo ws.jpg

CHALLENGE AIMSSellafield Ltd are looking for a solution to provide a 3D image/model of the subsurface around buildings where as-built records may not be as comprehensive as desired.It is anticipated that successful solution providers should be able to provide a desk study to demonstrate the feasibility of a non-invasive technique.Sellafield Ltd are interested in emerging technologies and techniques such as muon tomography, quantum hall sensing and quantum micro gravity. Please note that the scope of this challenge is not restricted to making use of these specific examples.It may be possible to deploy a device in one of the blind tubes, within the wider Sellafield blind-tube network, for a number of weeks before moving it to another in order to build up information and potentially stitch together surveys. It is acknowledged that there would likely be the need to reconstruct a significant amount of information for presentation or interrogation.A solution to this challenge would be considered to have broad applicability across the site and the mapping of buried services would provide an additional benefit.However, there is a current imperative to gather better information in relation to a known leak from a building on the Sellafield site, which is the single biggest source of in-ground contamination. The current leak from the Magnox Swarf Storage Silo Original Building (MSSS OB) and first extension was declared in 2019. The Magnox Swarf Storage Silos (MSSS) at Sellafield comprise an Original Building constructed in 1962 and three subsequent extensions constructed between 1972 and 1982. The silos contain magnesium cladding or ‘swarf’ that was stripped from Magnox fuel prior to reprocessing and stored under a layer of cover water. The leak rate is around 2.5m3 per day from the Original Building, which is embedded in the ground by approximately 6m.Due to the method of building construction and subsequent, poorly documented, interventions in the ground around the MSSS OB and first extension, the form of in-ground engineering is poorly constrained. There is evidence to suggest that engineering features may be influencing the migration of contamination away from the leak site, and gaining a better understanding of these features would help with developing mitigation strategies.The Original Building goes about 6m underground. Concrete screeding to stop the collapse of excavated slopes was used during construction and these features may be influencing leak migration. The first evidence of a leak occurred when building the first extension at which time considerable excavation and backfilling was undertaken. However, only limited records of the full extent of these works are available. The construction method used changed between the first extension and second extension being built.FIND OUT MOREPlease download the challenge statement for full details of this opportunity.You can watch a webinar and Q&amp;A session with the challenge owners for more information and details of how to apply.<iframe class="ql-video" frameborder="0" allowfullscreen="true" src="https://player.vimeo.com/video/933652837/"></iframe> The deadline for applications for this challenge is 4pm on Friday 26th April 2024 (revised from Friday 19th April).

Non-invasive imaging of in-ground structures

Sellafield Ltd is seeking technologies and approaches to identify the presence and composition of subsurface structures in the vicinity of buildings on the Sellafield site.Like many industrial sites of its age, Sellafield has a complex history of site use including the addition and removal of buildings over an extended period of time. This has resulted in a legacy of redundant physical forms both above and below ground level. This challenge is focussed on emerging technologies and techniques that can produce a 3D image/model of structures beneath ground, in particular around legacy waste storage facilities such as the Magnox Swarf Storage Silos (MSSS).

CC Informatics (CCI) has successfully demonstrated its innovative AssetScan technology to a group of 30 Sellafield staff, highlighting the potential of artificial intelligence to transform visual inspections in the nuclear sector.&nbsp;Held at the Centre of Excellence (CoE) Leconfield, the demonstration marked the conclusion of CCI’s proof-of-concept (PoC) project under the Game Changers open innovation programme. AssetScan was originally submitted through the programme’s General Application route, which allows solution providers to propose technologies that may benefit organisations including Sellafield Ltd, NRS Dounreay, and NRS Magnox.&nbsp;AssetScan is a patent-pending, trademarked AI product that automates the detection and measurement of defects in structural assets. Initially developed for use in the water industry, where it was applied to inspect masonry structures, the technology has now been adapted to suit the unique materials and conditions found on nuclear sites – including concrete, cladding and exposed steelwork.&nbsp;The demonstration outlined how AssetScan integrates high-resolution visual inspection data with photogrammetry and cutting-edge artificial intelligence. The process begins with either site-collected or provided imagery, which must meet specific criteria to enable accurate 3D modelling – namely image overlap and feature consistency across at least three views.&nbsp;Using industry-standard software, CCI constructs a photogrammetric 3D model of the structure. AssetScan’s AI engine, built on convolutional neural networks (CNNs), then processes the raw images to detect structural anomalies. These enhanced images are overlaid onto the 3D model, and orthorectified views of key surfaces are exported for post-processing and defect measurement.&nbsp;Throughout the PoC, CCI applied AssetScan to a range of Sellafield structures, with a particular focus on concrete and steel elements. The demonstration showcased the results of these trials, sparking insightful discussions among attendees about real-world applications in engineering and asset condition monitoring.<iframe class="ql-video" frameborder="0" allowfullscreen="true" src="https://player.vimeo.com/video/1094374220/"></iframe>"AssetScan represents a paradigm shift in visual inspection of large infrastructure, because our technology can be used to assess very large infrastructure holistically – which is something that a manual reviewer cannot do. It is a scalable solution that automates defect identification and tracking in huge image datasets – meaning more rapid detection of change, and provision of metrics that can assist human decision makers," said a CCI spokesperson. "We’ve demonstrated that AI, when combined with remotely collected survey data and 3D modelling, can significantly enhance the way visual inspection data is managed and reported on entire infrastructure systems – meaning better decisions, sooner, and resulting in better records to be kept for the future."As the nuclear sector seeks new ways to improve safety and operational efficiency, AssetScan stands out as a promising tool to support digital transformation in asset management. With its successful adaptation from the water industry to nuclear applications, the technology may soon play a vital role in supporting the long-term integrity of critical infrastructure.&nbsp;

The initiative focused on progressing the collaborative development of advanced <a href="https://www.gamechangers.technology/challenge/Condition_monitoring_and_inspection" rel="noopener noreferrer" target="_blank" style="color: rgb(70, 120, 134);">Condition Monitoring and Inspection (CM&amp;I) technologies</a>. These technologies are designed to monitor the evolution of nuclear waste and ensure the integrity of 3m³ waste storage boxes, crucial to Sellafield’s safety and environmental goals.&nbsp;At the heart of the project is the Range Resolved Hydrogen System, a state-of-the-art optical sensing technology being developed to detect and monitor hydrogen gas in nuclear waste stores. By using an upscaled Raman spectrometer, the system can detect hydrogen concentrations from distances up to 80 metres, providing real-time insights into gas evolution within storage environments.&nbsp;During the secondment, Charlotte worked alongside Fraunhofer experts to assemble and align the optical components of the system. The collaborative build phase included hands-on configuration of the laser-based detection apparatus, safety risk assessments related to laser usage, and preparation for upcoming field trials. This work plays a key role in developing an inactive demonstrator that will elevate the technology to Technology Readiness Level (TRL) 5, with elements of TRL 6.&nbsp;The placement not only advanced technical development but also fostered significant cross-sector learning. Sellafield staff gained specialist knowledge in optics and laser-based sensing, while Fraunhofer deepened its understanding of the complexities and operational constraints within the nuclear sector. The exchange sparked insightful discussions on procedural and cultural differences between industries, enriching both teams’ perspectives."I had a great time," said Charlotte Edge. "It was a very valuable experience being able to be hands-on with the technology and getting to explore new concepts. Thank you to Fraunhofer for this wonderful opportunity!"This secondment exemplifies the strength of industry-academic collaboration in solving some of the UK’s most challenging nuclear engineering problems. By combining Sellafield’s operational expertise with Fraunhofer’s technological innovation, the partnership is creating a path forward for safer, more effective nuclear waste monitoring.&nbsp;As testing of the hydrogen monitoring system moves forward, both organisations look to continue building on this successful collaboration – one that not only drives innovation but also strengthens cross-sector knowledge and capability.&nbsp;
