As part of the “<a href="https://www.gamechangers.technology/challenge/Analytical_Services:_Novel_separation_and_direct_measurement_technologies_for_radionuclides_and_analytes" rel="noopener noreferrer" target="_blank">Novel Separation and Direct Measurement Technologies for Radionuclides</a>” challenge set by the Analytical Services department at Sellafield Ltd, the University of York is developing a cutting-edge detection system aimed at revolutionising how radioactive samples are analysed. The research team hosted a pivotal mid-project demonstration at the School of Physics, Engineering and Technology, University of York, offering challenge owners and stakeholders a closer look at their progress.&nbsp;The project, led by Dr Christian Diget, seeks to overcome the limitations in the nuclear sector of in-liquid identification of alpha-emitting isotopes – a critical need in nuclear energy and decommissioning. In comparison, traditional approaches require preparation and processing of samples, which can be inefficient and time consuming.&nbsp;During the demonstration, a group of 11 attendees – including representatives from Sellafield Ltd, Game Changers delivery partner FIS360, and members of the university’s research group – gathered to observe a live test of the device using a radioactive source. The event offered a unique opportunity to see the hardware in action, explore the detection principles, and have in-depth technical discussions around specific use cases at Sellafield.<iframe class="ql-video" frameborder="0" allowfullscreen="true" src="https://player.vimeo.com/video/1145326771/"></iframe>Christian Diget, Academic, University of York said: “Traditional alpha radiation detection is slow and complex. Through Game Changers, we're developing in-situ technology that simplifies the process and expands its use across Sellafield and beyond - bringing real-world impact to a long-standing challenge.”&nbsp;Alongside Dr Diget, key contributors from the University of York include Dr Jamie Brown, Dr Samadhan Patil, and PDRA Alex Marchant. Their collective work has focused on refining sensor selection, device fabrication techniques, packaging design, and testing the chemical durability of the sensor components.&nbsp;This demonstration marked the halfway point of the team’s 12-month proof-of-concept (PoC) project, which began after the successful completion of a feasibility study in 2024. In parallel, the devices are undergoing bench and in-laboratory testing at multiple sites internationally. These collaborations are already helping to validate performance under varied operational conditions and are a critical step toward potential deployment.&nbsp;With the promise of improving how radioactive liquids are analysed, especially in high-precision environments such as Sellafield, this technology could play a key role in the future of nuclear measurement, safety, and decommissioning.

The University of York showcased its emerging in-liquid alpha detection technology to Sellafield and partners, demonstrating live testing of the prototype and its potential to transform radioactive sample analysis and nuclear decommissioning.

Following the successful completion of <a href="https://www.gamechangers.technology/news/Three_projects_advance_to_proof_of_concept_stage_in_Sellafield's_drum_deformity_detection_challenge" rel="noopener noreferrer" target="_blank">feasibility studies</a> in 2024, three innovative projects have now delivered fully demonstrable proof-of-concept (PoC) solutions to improve the inspection of highly radioactive waste drums at Sellafield.&nbsp;Sellafield Ltd is responsible for the safe, long-term storage of approximately 23,000 stainless steel drums, each containing uranium-bearing intermediate level waste (ILW). These 500L drums are kept in Sellafield’s Encapsulated Product Stores (EPS) and require inspection to monitor their condition. Some drums have previously exhibited signs of deformation due to chemical reactions within the drum contents, prompting the need for improved, high-accuracy measurement and monitoring methods.&nbsp;Because of the radioactive nature of the waste, inspections must be carried out inside shielded inspection cells. Any new inspection technology must therefore either operate within these high-radiation, confined environments or function remotely through multi-layered lead glass shield windows.&nbsp;Enhanced inspection capability will provide Sellafield and industry regulators with greater confidence in its understanding of how these waste packages evolve over time. This insight will inform the requirement for future inspections and interventions, potentially leading to costs savings and efficiencies.&nbsp;<h2>The Game Changers Challenge</h2>In response to this <a href="https://www.gamechangers.technology/challenge/Identifying_deformities_in_500L_drums" rel="noopener noreferrer" target="_blank">challenge</a>, Game Changers – working with the Retrievals East River at Sellafield Ltd – sought novel approaches that could be rapidly developed and deployed to deliver improvements as soon as practicable.&nbsp;Out of 21 applications received, four projects were taken forward for 12-week feasibility evaluations. Of those, three were selected to progress into full proof-of-concept development.&nbsp;All three proof-of-concept studies have now successfully demonstrated viable technologies, and discussions are underway to determine which approach will move forward into further development and eventual deployment.&nbsp;<h2>The Three Successful Proof-of-Concept Studies</h2><h3>Amentum – Laser Scan of Drum on Turntable</h3>Amentum developed a system using two commercially available laser line scanners to capture a 3D profile of a 500L drum as it rotates on an inspection turntable. The technology achieves sub-millimetre (&lt;1 mm) dimensional accuracy while compensating for practical issues such as off-centre or tilted drums. Its simplicity and robustness make it an attractive solution for integration into existing facilities. Find out more about the inactive demonstration carried out at Amentum's Birchwood facility in May 2025:<iframe class="ql-video" frameborder="0" allowfullscreen="true" src="https://player.vimeo.com/video/1093739149/"></iframe><h3>Cerberus Nuclear – DrumSight 3D</h3>Cerberus Nuclear advanced its DrumSight 3D system, employing COTS pan/tilt/zoom cameras mounted inside the inspection cell. Bespoke software reconstructs a 3D model of each drum as it is lifted from its four-drum stillage, enabling accurate deformation measurements without the need for turntable handling. This method enables inspection of the drum base and reduces the risk of handling drums that may already be significantly deformed. Find out more about the inactive demonstration carried out in April 2025:<iframe class="ql-video" frameborder="0" allowfullscreen="true" src="https://player.vimeo.com/video/1093740014/"></iframe><h3>University of Bristol – Edge Detection Software&nbsp;</h3>The University of Bristol created innovative software that processes images from existing through-window camera inspections to automatically detect drum edges as the drum rotates. This enables accurate dimensional measurements without needing to place any equipment within the radiation environment, offering a non-intrusive and easily deployable approach. An active demonstration took place at Sellafield site in February 2025. Find out more in this clip from FIS360 Project Manager Ellen Barker as part of June's Game Changers Technology Talk:<iframe class="ql-video" frameborder="0" allowfullscreen="true" src="https://player.vimeo.com/video/1129842842/"></iframe><h2>Next Steps</h2>All three technologies have demonstrated strong potential not only for 500L drum inspection but also for Remote Handling Intermediate Level Waste (RHILW) visual inspection applications across the Sellafield site and the broader Nuclear Decommissioning Authority (NDA) estate.&nbsp;The next phase of developments will include system refinements and active trials to determine deployability, and integration potential, as Sellafield Ltd and Game Changers determine which solution offers the best balance of accuracy, practicality, and radiation tolerance for operational use.&nbsp;These proof-of-concept successes mark a significant milestone in the journey to enhance Sellafield’s waste management capabilities – a clear demonstration of how collaboration, innovation, and targeted challenge-led development can drive progress in one of the most complex industrial environments in the world.&nbsp;

Three proof-of-concept projects – from Amentum, the University of Bristol, and Cerberus Nuclear – have demonstrated innovative technologies for detecting drum deformities at Sellafield, improving remote inspection accuracy, safety, and efficiency in managing radioactive waste storage.

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.
