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. <a href="https://forms.fis360.com/fis360ltd/form/GameChangerswebinarImmobilisingspringhangerassembl/formperma/ywK0ee71RvAKJP6IMgDo-wem-H2XUBcmB8nIwj-9NQU" rel="noopener noreferrer" target="_blank">Register to find out more.</a>

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.

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. Sellafield Ltd is seeking technologies to improve the efficiency of managing its Nuclear Safety Cases and these processes.

Challenge statement - Directional decontamination head deployment into large, congested, highly radioactive vessels.pdf

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.

UoN Snake web.png

The University of Nottingham’s (UoN) long-reach snake manipulator has achieved a landmark deployment at Nuclear Restoration Services (NRS) Dounreay, providing unprecedented access to areas inaccessible for decades. The success marks a significant step forward for modular manipulator technology that has been evolving through the Game Changers innovation programme since 2018.&nbsp;Developed through the Rolls-Royce University Technology Centre in Manufacturing and On-Wing Technology, the latest version of the snake manipulator represents a clear leap from earlier prototypes. Designed and built by UoN, with input and operational testing opportunities from NRS Dounreay, the device is capable of entering 30 mm apertures, navigating complex geometries, conducting 3D inspections, and carrying a sensor payload.&nbsp;In March 2025, the manipulator was operated on site by Ice9 Robotics with support from FIS360 Ltd and AevaSpec, a University of Glasgow spin-out. In a first-of-its-kind demonstration, the robot successfully navigated through a 30 mm aperture into a highly restricted area of the facility, capturing high-quality video and real-time radiation mapping data that will directly shape decommissioning strategies.&nbsp;<h2>From Prototype to Nuclear-Grade Tool&nbsp;</h2>The deployment builds directly on a March 2024 trial at NRS Dounreay, where the manipulator was first tested in an active nuclear environment. Learning from that earlier demonstration, the team has made substantial enhancements. These include:&nbsp;<ul><li>Improved LED lighting for sharper, clearer video capture&nbsp;</li><li>Increased manoeuvrability and payload capacity for greater operational flexibility&nbsp;</li><li>Integration of a miniaturised gamma radiation sensor from AevaSpec, delivering real-time dose-rate and spectroscopic data alongside visual imagery&nbsp;</li></ul>The sensor integration was a particularly important milestone. Co-developed by UoN and AevaSpec, the lightweight gamma detector was mounted without compromising navigability – something rarely achieved in confined-space robotic systems.&nbsp;Jason Simpson, Project Manager at NRS Dounreay, emphasised the operational impact:&nbsp;“The value of the snake manipulator lies in its ability to access areas previously out of reach, providing the critical data needed to shape decommissioning strategies and reduce risk remotely. By eliminating the need for intrusive investigative work, it delivers significant time and cost savings. For this project alone, the avoided costs exceed £1 million; if applied across other cells in the NDA estate, the potential savings could be truly substantial.”&nbsp;<h2>Engineering for Confined Space Challenges&nbsp;</h2>The manipulator’s modular design remains central to its adaptability. Length can be tailored from a few metres up to 20 m, combining low-cost, off-the-shelf components with 3D-printed connectors. Inflatable stabilisation balloons enable the head to lift and hold steady while carrying payloads, while a revolute joint provides fine vertical and rotational control for full 3D inspections.&nbsp;Such versatility is crucial in environments like Dounreay, where shielded hot cells, long stretches of ducting, and complex pipe networks were never designed with access or decommissioning in mind. Current solutions – borescopes or camera poles – offer only limited line-of-sight visuals near the ground. High-end snake-arm robots exist but are typically too large, too short in reach, or prohibitively expensive.&nbsp;By contrast, UoN’s system delivers a unique combination: small diameter, long reach, sensor integration, and low cost.&nbsp;Mark Crichton, Project Engineer at NRS Dounreay, highlighted the importance of the new insights:&nbsp;“The Snake ROV surveys have let us build up an invaluable picture of the cell underside infrastructure and services that have thus far evaded us through drawing searches.”&nbsp;<h2>A Growing Story of Collaboration&nbsp;</h2>The journey of the snake manipulator reflects years of sustained collaboration across academia, industry, and government. The project originated through the Robotics and AI in Nuclear Hub, where early trials with an aerospace snake robot highlighted the need for greater length and stiffness for nuclear deployment. Further development followed via the FIS360-managed Game Changers programme, with successful feasibility and proof-of-concept trials, leading to funding from the Robotics and AI Collaboration (RAICo) for continued development. Funding from NRS Dounreay then enabled the integration of radiometric sensing, ensuring the system was not just a vision but a working tool in one of the UK’s most challenging nuclear environments.&nbsp;Compared with the 2024 demonstration – when the prototype first solved a <a href="https://www.gamechangers.technology/news/Snake_robot_solves_40-year-old_nuclear_mystery" rel="noopener noreferrer" target="_blank">40-year-old mystery</a> inside a restricted-access cell – this latest deployment signals a maturing, nuclear-ready technology with clear commercial and cross-sector potential.<h2>Beyond Nuclear&nbsp;</h2>While nuclear decommissioning is a natural proving ground, the potential applications are broad. Aerospace, defence, petrochemical, and utilities sectors all face the same challenge: how to inspect and assess confined or hazardous spaces without exposing workers to risk.&nbsp;By bridging this gap, the University of Nottingham snake manipulator is not only helping to accelerate nuclear clean-up, but also laying the foundation for safer, faster, and more cost-effective inspection across industries.

Enhanced with radiation sensing and advanced manoeuvrability, the University of Nottingham’s snake manipulator has achieved a breakthrough deployment at NRS Dounreay – cutting costs, improving safety, and transforming access to previously unreachable nuclear environments.

Periscopic web 1.png

A pioneering camera and lens system developed by Ice Nine Ltd was successfully demonstrated to 16 key stakeholders from Sellafield Ltd at the RAICo1 innovation facility in Whitehaven. The ‘Periscopic’ system, a breakthrough in visual inspection for nuclear sites, is poised to revolutionise how confined and hazardous areas are inspected across the Sellafield site and potentially the wider Nuclear Decommissioning Authority (NDA) estate.The technology was <a href="https://www.gamechangers.technology/news/Innovative_technologies_receive_funding_to_enhance_asset_inspection_through_small_ports" rel="noopener noreferrer" target="_blank" style="color: black;">originally conceived</a> to address the “Asset Inspection through 19mm Diameter Access Ports” <a href="https://www.gamechangers.technology/challenge/Asset_inspection_through_19mm_diameter_access_ports" rel="noopener noreferrer" target="_blank" style="color: black;">challenge</a>. The technology demonstrated at the end of the proof-of-concept (PoC) project is a slender device capable of delivering sharp, colour, high-resolution imagery from areas previously considered too difficult or dangerous to access.<h2>Reimagining visual inspection in hazardous environments</h2>Many inspection zones at Sellafield are highly radioactive and notoriously difficult to access, presenting challenges for traditional electronic systems, which degrade quickly under such conditions. Conventional tools like borescopes and endoscopes are designed primarily for pipework and close-range viewing, often producing grainy, black-and-white images with limited detail.Ice Nine’s ‘Periscopic’ system is different.By drawing on the age-old principles of periscope design and integrating modern optical engineering, the system uses a series of lenses and mirrors to look through small access ports and view large internal spaces. Crucially, the camera hardware is kept outside the radiologically harsh environment, preserving image clarity and extending the system’s lifespan.“This is a game changer,” said one of the attending Sellafield stakeholders. “Not only does it give us eyes in places we’ve never been able to inspect before, but the image quality is a huge step change from anything we’ve previously used.”<h2>Demonstration &amp; industry reception</h2>During the live demonstration at RAICo1, attendees witnessed the Periscopic system in action. Feedback was overwhelmingly positive, with many praising the high image resolution and colour fidelity – a stark contrast to current inspection methods.<iframe class="ql-video" frameborder="0" allowfullscreen="true" src="https://player.vimeo.com/video/1110239730/"></iframe>A range of use cases was discussed during the event – environments where human access is impossible, and existing camera technologies fall short.The central Sellafield R&amp;D team who supported this recent project phase acknowledge the innovation’s potential for wider deployment and applications far beyond the original inspection challenge.<h2>Looking ahead: from concept to deployment</h2>The Periscopic project has been supported by the Game Changers programme, which funds novel technologies aimed at solving complex nuclear industry problems. With early feasibility and prototyping phases complete, Ice Nine is now preparing for further development, including hardware enhancements and features such as image stitching for panoramic views.Further on-site trials and active deployments will refine the system based on real-world requirements. With broad applicability across Sellafield and potential relevance across the entire NDA estate, this cost-effective, low-risk innovation represents a new frontier in remote inspection.“We’re incredibly proud of what we’ve achieved,” said a spokesperson from Ice Nine. “By combining centuries-old optics with today’s engineering, we’ve created a simple yet powerful tool that tackles a longstanding problem in a fresh way. We’ve really valued the input from Sellafield challenge owners that has enabled us to develop a relevant technology, whilst FIS360’s management has been vital in successful delivery of this project.”As Sellafield continues to prioritise safety, efficiency, and innovation, technologies like Periscopic mark a significant step forward – ensuring that even the most inaccessible corners of the site are no longer out of sight.
